Friday
Model: Archer T4U Plus  
Hardware Version: V1
Firmware Version: 1030.52.731.2025

Hi, few days ago I noticed that my T4U Plus drops 5GHz connection.

I reinstalled official drivers, forced in devices menager Wireless mode to IEEE 802.11a/n/ac then to IEEE 802.11ac.

As soon I start downloading something or open firefox, connection drops. In wireless mode auto connection is capped to 2.4Ghz 144Mbps.

I checked 5GHz with my phone (Iphone 15), 5Ghz 300Mbps (OK).

My router is Orange Funbox 3.0, Wifi 5&2.4Ghz combined.

I'm using this combo (Router & T4U Plus) for 2 years and was absolutely fine.

Windows connection specs on wireless mode auto:

My question is if my Archer is dying or I did something wrong?

Hi,

 

Can you test if the 5 GHz stays connected after you separate the 2.4 GHz band and the 5 GHz band into two different SSIDs on the Orange Funbox 3.0 ?

  @woozle Yes, I've already tried that. For some time 5Ghz is active then it disconnects and switch to 2.4GHz. WiFi status bar shows weak signal 2/5 but for 2 years as I mentioned was everythink fine, strong signal (my router is directly below Archer). Every other device shows full signal exepts Archer. I've bought Archer TX55E, so I will tell you if new Archer is working correctly or it was something router problem related.

Unfortunately my archer died. Even on 2.4GHz it will turn off itself every 10 seconds.

New Archer works fine (320 Mbps) but I have problem event with it. TX55E comes with built in Bluetooth (via Motherboard internal USB) but Windows 11 in device manager reports Code 43 "A request for the USB device descriptor failed". I've tried diffrent connector (JUSB1, JUSB2), reconnecting cable to Archer, but problem remains. I've tried to install drivers for BT but of course installer returns no bluetooth card found.

So, now you have two USB devices that won't work on your computer?

 

I am starting to wonder whether there might be a problem with the USB controller of your computer?

 

Can you please plug the Archer T4U in a different computer to verify it is really dead?
