Model: Archer T4E
Hardware Version:
Firmware Version: 2024.0.2.101

Hi all,

 

I just installed a TP-Link Archer T4E wireless adapter on a new PC build, but it is randomly dropping the connection to the 5GHz band.

 

I've had some luck reconnecting by either shutting down/turning back on the computer or disabling the device in Device Manager and then re-enabling. Though most times I'm just met with a "Cannot connect to network" error in Windows. (2.4GHz band usually works with this adapter, though it does throw the "Cannot connect" error occasionally as well)

 

I've tested with different devices (tablet and laptop) and they are able to connect with no issues. The laptop has actually been running on that same 5GHz wireless connection for about a year now, and I've never had issues with the signal dropping, and still don't. (Laptop not on/connected while having issues with the desktop connection)

 

The computer is physically in the same location as the laptop was, the router is in the laundry room, across the hall, maybe 25-30 feet away. The only obstruction between the adapter and the router is a wall and a door.

 

I'm at my wits end, I've tried uninstalling/reinstalling drivers, using the generic windows drivers (the ones installed with fresh windows install), using the TP Link drivers, resetting router, and nothing seems to work. In any case. 

 

Any suggestions would be highly appreciated.

 

Edit: If it matters, the router is an Arris SBG10

Try this driver to see if it clears up your 5G issues: link

 

You will need to manually install the .inf file for your respective system.

Yeah same here, worked perfectly for a year then all of a sudden been dropping randomly and would not connect. Even though it shows full signal it just keeps dropping. The TP Link from Tony is a even older driver from 2016 and honestly worked no better then current one. Even Windows own driver doesn't function any better. I think it could be a issue with Windows 10 in some update. I don't have another PC to test the T4E card in. Pretty much have to move on to some other solution.
