Hello, 

I have Archer TX3000E in my PC windows 11 and I have Archer C9 router

Only about a month back I start having a very strange issue, every time I connect my PC to the router, I cannot access the internet direclty it givs me DNS PORE issue or something like this, it takes about 30-60 sec then internet will start working.

I tried to investigate this issue but then I found that the issue is not limitted to the internet acess actually every time I connect my PC to the router wifi all devices connected to the router will be disconnected for a few secounds and then reconnected again thats include (WAN, LAN, WIFI) so every thing are disconnected. 

I checked other devices Mobile and laptop and other pc connected via LAN, when disconnect or reconnect them nothing happend, so the issue is only hapening with my PC.

I tried and used another router huwaui and checked if the same thing will happen, but acutlly there was no issues.

I though my Archer C9 router has gone defect so I decided to buy a new one (Archer AX55).

Today I recieved the new router and replaced my old one, however again I am facing the same exact issue, The moment I connect my PC to the router wifi all devices will be disconnect.

I though maybe my windows has some issue so I deleted all VPN apps, and deleted all network adapters and did a network reset, and restarted the PC but still I am having the same issue.

I think there is some issue between the tplink adapter (TX3000E) and tplinks routers which is causing this issue.

I did everything I could without sucess, please support
