Hello.

I Have an Archer C2 V1.
Sometimes the connection wi-fi is available, but my PC and phone can't connect.
The connection is there. 2.4ghz and 5ghz. Only don't connect.
I updated the firmware, but the problem continues.

Somebody know how to solve this problem?

Thanks

I have a modem connected too.
Modem of : 192.168.15.1
TPLINK 192.168.0.1

Can be a conflict between the two devices?
