This TP-Link 5 port 2.5G unmanaged switch is framed as a simple way to add faster wired networking without upgrading the whole home network. It fits well for NAS backups, Steam file transfers, and other local traffic when both devices support 2.5G, while the rest of the network can stay at 1G. The price is viewed as reasonable, and 2.5G is described as a practical middle ground versus pricier 5G or 10G gear. The main caveat is that the 15 percent Prime Visa back offer may not appear at checkout, and an 8 port version at $60 is preferred for most setups.

Common Questions (5)

  • Yes, especially if you frequently move large files or run backups to a NAS. A 2.5G link can make file transfers and full image backups noticeably faster than 1G, and it is a practical upgrade for home setups that already have 2.5G-capable gear.

  • Yes. You can plug only your 2.5G devices into the switch and they will communicate at 2.5G while the rest of your network stays at 1G or whatever speed your other gear supports. That makes it a low-effort upgrade for a router, mesh system, or existing switches.

  • Not for the full 5Gbps speed. To take advantage of the entire connection, you need switches and LAN gear rated at least 5Gbps; a 2.5G switch can still help individual devices on the local network, but it will not pass the full 5Gbps WAN speed.

  • No. The checkout screen may show only the normal 5% Prime Visa offer instead of the advertised 15% back, so the extra rebate appears to be inconsistent.

  • If you need more ports, the 8-port version at $60 is the better pick and was recommended over the 5-port model. The 5-port is still fine for a small 2.5G setup, but the 8-port gives more room to expand.

Motherboards and pre-built computers are more an more coming with 2.5G by default. Even access points now have 2.5G to accomodate faster speeds and more devices connected to it.

Yes, I know. Average user doesn't need 2.5G for their daily activities. But your computer might. For the more advance home users or those that care about not losing data may have a local NAS. Which may have automatic backups runing. It's a lot faster to do a full image backup over 2.5G than 1G.

$35 is good and happy to see the prices coming down.

Remember, high speed = high power consumption. Usually these devices used to be 5v and now its 9v, unless you have that much data to be transferred constantly as another user mentioned, you would not need it. I have a fairly large network at home including movie servers and NAS'es, Restic backup devices and StorjIO nodes. Multiple TVs streaming content such as news, YT, music, CCTV camers etc....... and I don't touch my 1GB limit, yes there are peaks but very few during the day.

What's the justification of getting this over the cheaper Chinese brands like Tenda, Real HD, and Brostrend? Is it just security concerns or is there a functional difference? I've seen the Real HD one for like $37 recently.

YMMV there, apparently - the 15% offer is not present when I check out with this. It just shows the normal 5%.
You have Prime card AND are a Prime member? Either the Chase or Synchrony will work

Could be useful if you're updating Steam games and transferring update files from one PC already updated... that said both PCs need 2.5G...

Most home user don't need more than 1 Gbps of speed. Those who need 2.5G or 10G are likely to be professionals who need to transfer large files over the network constantly.
If you do anything with media even 2.5 can be painfully slow. I'm surprised we're not already all using 10 by now.

If you have a NAS that you are frequently accessing and a fairly recent router/mesh/home network setup already with 2.5G ports then you will likely benefit from 2.5G even as a home user . Not a must by any means but a welcome upgrade for very little work and money
Can confirm, I have 2.5G networking for my homelab and transferring files/doing backups is noticeably faster.
I think 2.5G equipment is cheap enough for home use. 5/10G equipment can get pricey though

Quote from CrimsonPen992 View quoted comment :
A 1 gigabit port consumes/dissipates about 0.25W of power/heat. This means 16 ports of gigabit use about 8-14W. A 1600G port uses something like 25-30 watts per port for transmission and then 20-40 watts per port for processing, or 45-70 watts per port, meaning a 5 port switch would run 300W which is going to be spicy both in heat and noise. 10G RJ45 uses between 2.5-5 watts of power per port, which is is at least 10x what 1G uses and is still challenging to manage.

However, 10G SFP+ connections - fiber-optic 10G? It uses 0.1 to 1.5W per port when using fiber or DAC (the SFP+->RJ45 converters use up to 3W, which gets really hot and can burn ports out if there isn't enough active cooling, if you use them, ideally use the long range ones on short runs). It doesn't have to do as much processing as 10G RJ45 does, so it's much more efficient and the gear is often much cheaper. But home users don't do well with fiber and DAC cables top out at limited run lengths, so it's not widely adopted by home users.
Excellent writeup! Through trial and error and over time, I discovered what you've succinctly summarized and now run 1/2.5GbE over twisted pair throughout the house and 10G over DACs in the room with my servers/NAS

In my experiments, I discovered that I could run 10GbE over most CAT5e runs in my walls but the power consumption turned out to be more than I wanted to deal with.

This is super. Now I can run a high speed cable to my toilet desktop. The WiFi through the bathroom tiles and porcelain creates issues. This should make images & videos load quicker.
