TP-Link Archer T2U (AC600) Dual-Band WiFi 5 Nano USB Wireless Adapter

It gave good speed for 5 minutes on my Media PC (41 Mbps versus over 140 Mbps+ for my laptop), but then dropped to 0.7-1.4 Mbps. When I ejected the nano it was physically hot.

Now, this may be a dud unit, but heat was often mentioned on the tplink forum I turned to; a concerning issue. Another thing I noticed was that the claim you can "choose" 2.4 or 5 Ghz is an untruth. If you broadcast separate SSID's then yes, but if there is one signal, the T2U defaults to 2.4Ghz (my guest network is 5 Ghz but when I tried that, all I got was 1.4 Mbps!).

Again, when I turned to the tplink forum this came up as an issue too. The T2U may present as being new tech but this is old technology and a worrying sign upon opening is that it came with a CD-ROM! When I installed the driver online as I was looking to upgrade from my 2011 receiver, it dated from 2020. After this, the connection was up and down like a yoyo, so I updated the driver, and Windows downloaded one from 2024. As speed was non-existent (heat I respect), I uninstalled and reinstalled the drivers, but the 2024 version I had vanished, leaving me with the stock 2020 driver that is buggy.

Conclusion
I put my 2011 wifi 2.4Ghz receiver back in the media PC and instantly doubled my speed (ok to 4Mbps). The T2U Nano is not a recommended product and I am returning to PBTech for a refund.

I recently purchased the TP-Link Archer T2U (AC600) WiFi adapter to upgrade my old desktop PC, and it's been a game-changer. The installation was incredibly easy – just plug it into a USB port, and it was ready to go.
I use it for everyday use and online streaming and gaming. The compact size is a huge plus, as it doesn't block other USB ports, and it's so small that I can leave it plugged in all the time without any hassle. The performance has been consistently reliable, with no dropouts or connectivity issues.Overall, I'm very happy with this purchase.

I have used this company’s products for many years. Great range (distance) especially considering the tiny USB module. Relatively inexpensive considering features.

Used for 6 months. Started disconnecting from wifi and data slowed. Completed a speed test - Download has dropped right off 1-2MB. My Iphone X is 10 times faster. Uploads are similar speed.

I bought the first one on 30-Sep-2021. It broke down mysteriously around 20-Jul-2022.
I bought the second one, on the same day. By Aug-2022, it too stopped working, all of a sudden !!!!

Their firmware seem to have a bug and don't get installed/loaded.
On linux, dmesg shows:

This wifi USB works really well with Debian 12. It is not plug and play though, it requires a driver installation. Once the driver is installed , it works flawlessly.

Was easy to set up and works well. Now we can choose where to put our old computer, free of cables. Was easy to set up and works well. Now we can choose where to put our old computer, free of cables.

The product works great, but internet is necessary for the driver installation if your PC doesn't have a CD drive, which is a little annoying, but the product works great once it's set up.

Worked great after downloading the driver. Worked great after downloading the driver.
