Problems getting AX6000 to connect to Win 11 desktop

[Euroscpetic]

Hi All

Have recently installed above router to improve WiFi throughout house, particularly son’s bedroom. Am using it in access point mode so that I can retain our digital phone, which needs to be connected to Sky SR203 router. (We have FTTP) 

The only glitch has been getting a Windows 11 desktop to connect to either the 2.4 or 5Ghz networks. It often disconnects and then struggles to reconnect. (“Can’t connect to network message”) We only have bog standard three bed semi, no think walls. The router is positioned at foot of stairs and bedroom at top.

I think it may be more to do with the WiFi adaptor in the pc. I replaced the old one with a TP link AC1200 and had issues getting that to work with the original set up. Had to keep resetting/uninstalling adapter etc.

The only other thing I can think off is Firewall/anti virus. I turned off during router installation but assume these should be good to run now?

Any advice/fixes would be greatly appreciated.

Thanks

Hi again

Further update. It miraculously started connecting (on WPA3) around 30mbps. Changed to the combined WPA3/4 and now connecting at 40mbps. 

The AC1200 is an Archer T4E. Don’t know if that makes a difference. Advertised as pci Express Adapter. Didn’t realise it was 9 years old, as just bought new from Jeff Bezos. 

When I check WiFi adapter properties (events), it shows  disconnections as “device not started (RTWlanE01)”.

The FW version is 3.0.0.4.388_33404-gaac0095. Not sure where to get bios, or check it’s up to date.

Thanks again

Amazon UK has the Archer TX20E, and you can return/exchange the T4E if I'm not mistaken.

Quite clearly T4E on box. I think I may have resolved it now. I downloaded and installed drivers from to link website, and it’s connecting at 100mbps now-no dropouts so far. 

Thanks for your help.

Tp link.

It's probably because Mr Bezos gets a vast amount of sales here, but Amazon has free shipping for above certain shopping cart $ amount, also free return shipping, and no restocking fee...
