Q1: “What is port forwarding and how do I set it up?”

The firewall in a home networking router blocks all incoming traffic unless it's related to outgoing traffic. Port forwarding allows designated incoming UDP or TCP traffic (identified by a port number) through the firewall. It's commonly used to allow remote access to a device or service in the home network, such as peer-to-peer games.

These homegrown guides provide more information about port forwarding (and its cousins, DMZ and port triggering) and how to set it up:

Q2: “What category cable do I need for Ethernet?”

CAT 5e, CAT 6 and CAT 6A are acceptable for most home networking applications. For 10 Gbps Ethernet, lean towards CAT6 or 6A, though all 3 types can handle 10 Gbps up to various distances.

Contrary to popular belief, many CAT 5 cables are suitable for Gigabit Ethernet. See 1000BASE-T over Category 5? (source: flukenetworks.com) for citations from the IEEE 802.3-2022 standard. If your residence is wired with CAT 5 cable, try it before replacing it. It may work fine at Gigabit speeds.

In most situations, shielded twisted pair (STP and its variants, FTP and S/FTP) are not needed in a home network. If a STP is not properly grounded, it can introduce EMI (ElectroMagnetic Interference) and perform worse than UTP.

Q3: “I bought this flat CAT 8 cable from Amazon but I’m only getting 95 Mbps”

95 Mbps or thereabouts is a classic sign of an Ethernet connection running only at 100 Mbps instead of 1 Gbps. Some retailers sell cables that don't meet its category’s specs. Stick to reputable brands or purchase from a local store with a good return policy. You will not get any benefit from using CAT 7 or 8 cable, even if you are paying for the best internet available.

If the connection involves a wall port, the most common cause is a bad termination. Pop off the cover of the wall ports, check for loose or shoddy connections and redo them. Gigabit Ethernet uses all 4 wire pairs (8 wires) in an Ethernet cable. 100 Mbps Ethernet only uses 2 pairs (4 wires). A network tester can help identify wiring faults.


Q4: “Why won’t my Ethernet cable plug into the weird looking Ethernet jack?” or “Why is this Ethernet jack so skinny?”

TL;DR In the next link, the RJ11 jack is a telephone jack and the RJ45 jack is usually used for Ethernet.

RJ11 vs RJ45 (Source: diffen.com)

Background:

UTP (Unshielded Twisted Pair) patch cable used for Ethernet transmission is usually terminated with an RJ45 connector. This is an 8 position, 8 conductor plug in the RJ (Registered Jack) series of connectors. The RJ45 is more properly called a 8P8C connector, but RJ45 remains popular in usage.

There are other, similar looking connectors and corresponding jacks in the RJ family. They include RJ11 (6P2C), RJ14 (6P4C) and RJ25 (6P6C). They and the corresponding jacks are commonly used for landline telephone. They are narrower than a RJ45 jack and are not suitable for Ethernet. This applies to the United States. Other countries may use different connectors for telephone.

It's uncommon but a RJ45 jack can be used for telephone. A telephone cable will fit into a RJ45 jack.

Refer to these sources for more information.

RJ11 vs RJ45


Q5: “Can I convert telephone jacks to Ethernet?”

This answer deals with converting telephone jacks. See the next answer for dealing with the central communications enclosure.

Telephone jacks are unsuitable for Ethernet so they must be replaced with Ethernet jacks. Jacks come integrated with a wall plate or as a keystone that is attached to a wall plate. The jacks also come into two types: punchdown style or tool-less. A punchdown tool is required for punchdown style. There are plenty of instructional videos on YouTube to learn how to punch down a cable to a keystone.

There are, additionally, two factors that will determine the feasibility of a conversion.

Cable type:

As mentioned in Q2, Ethernet works best with CAT 5, 5e, 6 or 6A cable. CAT 3, station wire and untwisted wire are all unsuitable. Starting in the 2000s, builders started to use CAT 5 or better cable for telephone. Pop off the cover of a telephone jack to identify the type of cable. If it's category rated cable, the type will be written on the cable jacket.

Home run vs Daisy-chain wiring:

Home run means that each jack has a dedicated cable that runs back to a central location.

Daisy-chain means that jacks are wired together in series. If you pop off the cover of a jack and see two cables wired to the jack, then it's a daisy-chain.

The following picture uses stage lights to illustrate the difference. Top is home run, bottom is daisy-chain.

Home run vs Daisy-chain (source: bhphoto.com)

Telephone can use either home run or daisy-chain wiring.

Ethernet generally uses home run. If you have daisy-chain wiring, it's still possible to convert it to Ethernet but it will require more work. Two Ethernet jacks can be installed. Then an Ethernet switch can be connected to both jacks. One can also connect both jacks together using a short Ethernet cable. Or, both cables can be joined together inside the wall with an Ethernet coupler or junction box if no jack is required (a straight through connection).

Above diagram shows a daisy-chain converted to Ethernet. The top room has a simple Ethernet cable to connect both jacks together for a passthrough connection. The bottom room uses an Ethernet switch.


Q6: “Can I rewire my communications enclosure for Ethernet?”

The communications enclosure contains the wiring for your residence. It may be referred to as a structured media center (SMC) or simply network box. It may be located inside or outside the residence.

The following photo is an example of an enclosure. The white panels and cables are for telephone, the blue cables and green panels are for Ethernet and the black cables and silver components are for coax.

Structured Media Center example

One way to differentiate a telephone panel from an Ethernet panel is to look at the colored slots (known as punchdown blocks). An Ethernet panel has one punchdown block per RJ45 jack. A telephone panel has zero or only one RJ45 for multiple punchdown blocks. The following photo shows a telephone panel with no RJ45 jack on the left and an Ethernet panel on the right.

Telephone vs Ethernet patch panel

There are many more varieties of Ethernet patch panels, but they all share the same principle: one RJ45 jack per cable.

In order to set up Ethernet, first take stock of what you have. If you have Ethernet cables and patch panels, then you are set.

If you only have a telephone setup or you simply have cables and no panels at all, then you may be able to repurpose the cables for Ethernet. As noted in Q2, they must be Cat 5 or better. If you have a telephone patch panel, then it is not suitable for Ethernet. You will want to replace it with an Ethernet patch panel.

In the United States, there are two very common brands of enclosures: Legrand OnQ and Leviton. Each brand sells Ethernet patch panels tailor made for their enclosures. They also tend to be expensive. You may want to shop around for generic brands. Keep in mind that the OnQ and Leviton hole spacing are different. If you buy a generic brand, you may have to get creative with mounting the patch panel. You can drill your own holes or use self-tapping screws. It's highly recommended to get a punchdown tool to attach each cable to the punchdown block.

It should be noted that some people crimp male Ethernet connectors onto their cables instead of punching them down onto an Ethernet patch panel. It's considered a best practice to use a patch panel for in-wall cables. It minimizes wear and tear. But plenty of people get by with crimped connectors. It's a personal choice.


Q7: “How do I connect my modem/ONT and router to the communications enclosure?”

There are 4 possible solutions, depending on where your modem/ONT and router are located relative to each other and the enclosure. If you have an all-in-one modem/ONT & router, then Solutions 1 and 2 are your only options.

Solution 1. Internet connection (modem or ONT) and router inside the enclosure

This is the most straightforward. If your in-wall Ethernet cables have male Ethernet connectors, then simply plug them into the router's LAN ports. If you lack a sufficient number of router ports, connect an Ethernet switch to the router.

If you have a patch panel, then connect the LAN ports on the router to the individual jacks on the Ethernet patch panel. The patch panel is not an Ethernet switch, so each jack must be connected to the router. Again, add an Ethernet switch between the router and the patch panel, if necessary.

If Wi-Fi coverage with the router in the enclosure is poor in the rest of the residence (likely if the enclosure is metal), then install Wi-Fi Access Points (APs) in one or more rooms, connected to the Ethernet wall outlet. You may add Ethernet switches in the rooms if you have other wired devices.

Solution 2: Internet connection and router in a room

In the enclosure, install an Ethernet switch and connect each patch panel jack to the Ethernet switch. Connect a LAN port on the router to a nearby Ethernet wall outlet. This will activate all of the other Ethernet wall outlets. As in solution 1, you may install Ethernet switches and/or APs.

Solution 3: Internet connection in a room, router in the enclosure

Connect the modem or ONT's Ethernet port to a nearby Ethernet wall outlet. Connect the corresponding jack in the patch panel to the router's Internet/WAN port. Connect the remaining patch panel jacks to the router's LAN ports. Install APs, if needed.

If you want to connect wired devices in the room with the modem or ONT, then use Solution 4. Or migrate to Solutions 1 or 2.

Solution 4: Internet connection in the enclosure, router in the room

This is the most difficult scenario to handle because it's necessary to pass WAN and LAN traffic between the modem/ONT and the router over a single Ethernet cable. It may be more straightforward to switch to Solution 1 or 2.

If you want to proceed, then the only way to accomplish this is to use VLANs.

  1. Install a managed switch in the enclosure and connect the switch to each room (patch panel or in-wall room cables) as well as to the Internet connection (modem or ONT).
  2. Configure the switch port leading to the room with the router as a trunk port: one VLAN for WAN and one for LAN traffic.
  3. Configure the switch ports leading to the other rooms as LAN VLAN.
  4. Configure the switch port leading to the modem/ONT as a WAN VLAN.
  5. If you have a VLAN-capable router, then configure the same two VLANs on the router. You can configure additional VLANs if you like for other purposes.
  6. If your router lacks VLAN support, then install a second managed switch with one port connected to the Ethernet wall outlet and two other ports connected to the router's Internet/WAN port and a LAN port. Configure the switch to wall outlet port as a trunk port. Configure the switch to router WAN port for the WAN VLAN, and the switch to router LAN port as a LAN VLAN.

This above setup is known as a router on a stick.

WARNING: The link between the managed switch in the enclosure and router will carry both WAN and LAN traffic. This can potentially become a bottleneck if you have high speed Internet. You can address this by using higher speed Ethernet than your Internet plan.

Note if you want to switch to Solution 2, realistically, this is only practical with a coax modem. It's difficult, though, not impossible to relocate an ONT. For coax, you will have to find the coax cable in the enclosure that leads to the room with the router. Connect that cable to the cable providing Internet service. You can connect the two cables directly together with an F81 coax connector. Alternatively, if there is a coax splitter in the enclosure, with the Internet service cable connected to the splitter's input, then you can connect the cable leading to the room to one of the splitter's output ports. If you are not using the coax ports in the other room (e.g. MoCA), then it's better to use a F81 connector.


Q8: “What is the best way to connect devices to my network?”

In general, wire everything that can feasibly and practically be wired. Use wireless for everything else.

In order of preference:

Wired

  1. Ethernet
  2. Ethernet over coax (MoCA or, less common, G.hn)
  3. Powerline (Powerline behaves more like Wi-Fi than wired; performance-wise it's a distant 3rd)

Wireless

  1. Wi-Fi Access Points (APs)
  2. Wi-Fi Mesh (if the nodes are wired, this is equivalent to using APs)
  3. Wi-Fi Range extenders & Powerline with Wi-Fi (use either only as a last resort)

TP-Link potential U.S. ban discussion

237 Upvotes

[Edit: Added AI summary because some people were not aware of the situation.]

Please discuss all matters related to the potential ban of TP-Link routers by the U.S. here. Other, future posts will be deleted.

The following is an AI summary:

The US government is considering a ban on TP-Link routers due to cybersecurity concerns and potential national security risks.

Why the consideration?

Security flaws

TP-Link has had security flaws and some say the company doesn't do enough to patch vulnerabilities

Links to China

TP-Link is a Chinese company and some are concerned about its ties to China

Chinese threat actors

Chinese hackers have broken into US internet providers, and some worry TP-Link could be compromised

TP-Link's response

  • TP-Link says it's a US company that's separate from TP-Link Tech in China

  • TP-Link says it's working with the US government to address security concerns

  • TP-Link says it doesn't sell routers in the US that have cybersecurity vulnerabilities

What happens next?

The fate of TP-Link routers is still uncertain

If the government decides to ban TP-Link, it might replace existing routers with American alternatives

As noted, no ban has been instituted, nor is it clear whether some or all TP-Link products will be included.

Issues with wall jacks in new home

Post image
12 Upvotes

I am (largely) clueless when it comes to networking stuff. We just moved into our new home and have been having some issues with the Ethernet ports around the house. We were able to connect the ONT on the ground level to the router on the 2nd level with a wire in our control box to a port in the 2nd floor office. When they installed the box, they originally connected all the wires for a phone patch panel (I think?) for some reason. We had them come back out and add RJ45 caps to the wires instead. I am now trying to feed back from the router using a second port we have in the office to a switch in the control box. I’m able to see connection but the switch flashes orange.

When I connect a device it says Ethernet and has an IP but there is no actual connection to the internet. I used a tester and it looks like pin 1 is not lighting up. I re-capped the end of the cord in the box myself (surely I did it right lol) and the result was the same. I pulled the piece out of the wall and it looks like it’s a keystone jack which is something I’ve never messed with. Is this likely where the issue is? Any other suggestions?

I have tested the cord I’m using router to wall and tried a different cord. This all seems fine. I also directly connected the switch to the router and it also seemed fine

Unable to use walljacks for ethernet

Thumbnail

50 Upvotes

Howdy all. I’ve reached my capacity in trying to figure out how to achieve an ethernet connection in my bedroom/office by using the walljacks.

For context:

I have a 3 story place -

Garage on the bottom floor has the ONT box with my tp link switch connected to it along with the 4 cables connected to it for the 4 ethernet walljacks that are available upstairs.

Middle floor - lounge ethernet jack where my net gear xr1000v2 router is connected. This allows me to get wifi so that tells me my current configuration is somewhat right.

Upper floor- bedrooms with ethernet jacks.

My problem- the top floor ones are not working.

Any tips would be appreciated- thank you!

Need help planning outdoor Wi-Fi coverage for a 2-acre property

3 Upvotes

Hi everyone,

I know questions like this have been asked many times, but since mesh Wi-Fi tech keeps evolving and getting more accessible, I’d love to get some fresh input.

I recently bought a property that's about 2 acres in size, and I'm planning my Wi-Fi setup. The house is small (under 1000 sq ft, single story), so I don’t expect coverage issues inside. However, I’d really like to have reliable Wi-Fi outside, especially at the pool and in the garage.

🧾 A few details:

  • I’m located in Canada, but feel free to share US product links — I can likely find the Canadian equivalents
  • I’ll have 1Gb fiber internet
  • The garage is ~30 ft from the house
  • The pool and outdoor kitchen are ~100 ft from the house
  • Cell reception is weak
  • Running Ethernet cables is not an option — wireless is a must

🎯 My goals:

  • I work from home and need fast, reliable internet inside
  • I’m installing a Sonos system across the property (house, deck, pool, garage), so I need stable Wi-Fi for high-quality audio streaming
  • I don’t need full 1Gb speeds everywhere, but I want enough bandwidth in key areas for video and audio streaming

🤔 What I need help with:

  • What kind of router would you recommend for inside the house?
  • What’s the best current (and affordable) way to extend Wi-Fi reliably to the garage and pool area? (Mesh system? Extenders? Repeaters?)

I'd prefer to start with a budget-friendly setup and upgrade over time if needed.

Thanks a lot in advance for any advice!

Unsolved Looking for help with utp cabel

Thumbnail

Upvotes

Hi all!

I have utp sockets all around the house, and they are led to a router. Sockets looks fine, and wiered in type B. On the router end it is type B as well (right, white cable). But nothing works :D

So I bough a tester, nothing fancy a simple one where LEDs are lighting up one after another. I have a cable, which I guess connected like type B (left).

With only the cable and the tester it works fine. But when I connect the remote part of the tester to the socket with my cable, and master part to the end at the router it won’t light up.

If the type would be mixed up, leds would ligh up but in different order on the remote and master part of it. If there is a break in the cable it should light up red ( I think, I don’t have a broken cable to test it.)

What could have been gone wrong? My tester cable mixing up everything? Or the one at the router end are wiered wrong? As much as I see on the router end the claws are in, and touching the cable.

Wall RJ45 issue

Upvotes

Hi, total noob here.

I just moved in to a new appartment and I'm trying to figure out why this ethernet plug does not work.

When I plug a cable in any computer it says "No cable is connected" (yes, the other end is connected to my switch), so I removed the wall plate and this is what I see.

I know nothing about cabling so I can't tell if something is wrong. Any idea what could be the problem?

Mobile Broadband Antenna UK

Upvotes

Hey all been lurking for sometime and this is most likely a silly question but don't want to make an absolute mess of it.

I've got a directional antenna so I'm hoping this alone should help fix in on a single mast

So I've been testing on my mobile and it seems I'm bang in the middle of two masts 0.5 miles either way; one serving 4G the other 5G I want to ask if a directional pointed towards the 5G mast shouldn't face any problems picking up the less desirable mast?

Sounds stupid I know because the answer is in the name... Thanks 🙏 Just wanting to make sure.

Advice UDM Pro 192.168.1.0/24 subnet to Mikrotik 10.10.0.0/24 subnet

Upvotes

Hey guys,

I'm trying to span my networking knowledge and I have been at this for a couple days. I am trying to use a mikrotik CRS310-1G-5S-4S switch that will be for my Homelab network using the subnet 10.10.0.0/24. My main network is my UDM pro on the 192.168.1.0/24 subnet.

What I've done so far to configure this is using static routes to point to the mikrotik switch and vise versa.

UDM Pro Static Route: Dest. 10.10.0.0/24. - next hop: 192.168.1.5
Mikrotik static route: Dest. 192.168.1.0/24 - Gateway address: 192.168.1.1
I've set a bridge on the mikrotik for ether1 and gave that bridge a 192.168.1.5 address
I've set the IP for ether1 to 10.10.0.2/24
I've set the IP for SFP1(server1) to 10.10.0.8

Anytime I try to connect to a server on 10.10.0.8 it opens the mikrotik gui. I understand this may be a simple solution for some but networking isn't my strong suit. I've probably worked on this too long and am missing something.

Advice AT&T Fiber routing in new apartment

Thumbnail

42 Upvotes

I moved to a new apartment and got an AT&T fiber service, but the fiber box is in a very inconvenient location (closet of the bedroom on the opposite side from my setup). There’s a patch panel (I think) next to the fiber box and a series of cat5e+ outlets around the apartment. I have almost zero networking knowledge and am looking for advice on whether or not it’s possible to use this patch panel or the pre installed blue ethernets to somehow run a gigabit Ethernet signal to the Ethernet outlets around the apartment. I’ve attached photos of the panel, the patch panel, and one of the outlets.

Wifi router recommendation

Advice for buying wifi router

Good morning, I own a fixed line subscription to Fastweb with the proprietary modem (nexxt). I would like to know if you think it is possible to use another modem that has the function of connecting to a SIM card with internet access in case the wifi signal is interrupted (for security issues). Could you please recommend a router that is able to do this? (And, I don't know if it exists or but if there is a router with built-in UPS for the same reason as before) Thanks to all

Rede local

Uma dúvida, desinstalei meu whatsapp e quando fui reinstalar apareceu essa imagem, sendo que esse wifi (que tá riscado) é da casa do meu ex. Eu não entendo nada disso, mas ele trabalha no provedor de internet aqui da minha cidade. Isso é só uma ilustração genérica, ou minha rede tem algo a ver com a dele?

Unsolved IP Netzwerke verbinden.

0 Upvotes

Nach langem suchen habe ich beschlossen mein Problem zu teilen. Also ich bin komplett unerfahren mit Netzwerken da ich Elektriker und kein Netzwerktechniker bin.

Die Problematik ist folgende :

Wir haben eine Photovoltaik Anlage verbaut die ziemlich groß ist. Jetzt hat der Netzbetreiber ein Fernworkgateway installiert und uns Vorgaben gegeben wie die Dinge miteinander kommunizieren sollen.

Hier einmal die Angaben die gegeben sind

Ist:

(Heimnetz) 192.168.1.0/24 über LTE Router RTU955 Im Heimnetz ist ein SMA Data Manager Und im Heimnetz ist der Wechselrichter

Das vom Netzbetreiber gegebene Netzwerk ist 10.0.0.0/30

In dem 30er Subnetz sind alle Teilnehmer belegt bis auf einer, der dann eine Komponente aus unserem Heimnetz werden soll.

Jetzt die Besonderheiten.

  • Wir haben keinen Zugriff auf das Gateway des Netzbetreibers 10.0.0.1

-Unser Data Manager soll die 10.0.0.2 bekommen und nach IEC 60870-5-104 kommunizieren können.

-wenn der Data Manager die 10.0.0.2 bekommen hat wollen wir aber trotzdem noch auf den Data Manager in dem 192er Netzwerk drauf zugreifen können und Fernzugriff gewährleisten.

-Der LTE Router und das Fernworkgateway sind über LAN Kabel miteinander verbunden.

-mit einer Routing Option vom 192er auf den 10er konnten wir auch einmal die mac Adresse von 10.0.0.1 sehen, also das schien schon geklappt zu haben.

Und nun bin ich ein wenig überfordert wie genau die Einstellungen vorzunehmen sind.

Wenn noch Angaben benötigt werden kann ich diese gerne geben, sofern ich diese besitze.

Advice Switching out hardware

0 Upvotes

I’m switching my parents modem out from an all-in-pne from xfinity that they’ve been renting for too many years.

I got a surfboard modem and to link archer WiFi router.

But I realized their existing modem/router has a telephone jack that they run their home phone out of. Is there an adapter that I can put from the WiFi router that is a cat jack male to make it a telephone jack female to work for their home phone?

Unsolved Unable to ping but fine wifi connection

1 Upvotes

So basically i was trying to connect my windows laptop to my mac minecraft LAN server, yet i was unable to connect at all. At first i thought it was because of bad ports or something but i realised that i cant connect to ANY minecraft server, not hypixel, aternos, etc. So i tried pinging some servers, and none of them worked. at first i tried my mac, then google, then cloudflare. EVERY SINGLE ONE OF THEM returned with general failure but peculiarly, when i try pinging on mac its totally fine and even weirder i can still use the internet perfectly fine on that windows laptop. does anyone have any idea what is happening?

Advice Ubiquiti UniFi AC Pro Standalone Dropouts

1 Upvotes

Hi all,

So I am very new to home networking and just starting out, I installed a Ubiquiti UniFi AC Pro as just a standalone device as my house is only small powered by POE now for the past 2 years it was running great and have had zero issues, however in the past month I started to notice the wifi would disconnect every 10-15 minutes and as the weeks went on it go worse to the point it's now every 1-2 minutes. I connected to my modem wifi network and no issues but as soon as I connect back to the Unfi access port it's starts again.

Just wondering if anyone has any ideas where I should start?

Thankyou

New home internet

Post image
1 Upvotes

Hello all,

Moving into our new home. We have these connections in three different rooms (see picture) (one on each floor).

I’m old school. You have coaxial cable to modem, modem to router and pray it covers the area. So this is all new to me.

I’ve been looking into WiFi mesh like Eero Max 7 or Orbi 970. But what would be the best way to set up internet with our own equipment? For context we will probably use Xfinity and have numerous smart devices, game consoles etc. our TVs are smart, but we actually use Apple TV to stream all the services (Disney, Hulu, Max. Etc)

Any input, advice or suggestions on 1) ensure adequate WiFi through our 3,500 sq ft (about 1,000 per floor) and 2) make use of these ethernets to help minimize the strain on WiFi.

Thanks!

Looking for an inexpensive UPS with removable batteries

6 Upvotes

I'm looking for a relatively inexpensive UPS that supports "generic" replacement batteries (i.e., 12v 7ah, 6v 4.5ah, etc.) Something that doesn't require expensive proprietary rechargable batteries.

Unfortunately, it seems like many of these sorts of UPS's are rather costly and geared for business network racks.

Any suggestions for home-network UPS's that fit this criteria?
