faced with issue when 3 of my tv can not connect to wifi network, I am using Archer C7 and 19.07.2.
Configuration simple as hell and android phones can connect and use internet over open and encrypted network. In the same time all three tv's can't connect to open wi-fi (Different brands Sony, Skywarth, android tv box).
Here is my wireless file:
I disabled Ipv6, disable adblock, but looks like problem on hardware level.
I tried to use different channels (1,6,7,11), I tried 5 Ghz and 2.4 Ghz. Tried different countries, different power transmission. No luck.
Maybe someone faced the same and know where is the problem.
Looks like the culprit is simultaneous LAN and WIFI connection. Just removed LAN and could connect to open network. Strange, it never was a problem on old TP-Link WR-1043nd. Anyone can help, how I can be connected with lan and wifi in the same time.
There's no reason to connect a TV by LAN and wifi at the same time. When it's possible to use LAN, do that as it is better performance. So the TV is probably set up to use the LAN connection preferably and not use wifi when LAN exists.
No. My device are always connected to wire. But sometimes (rarely) I turned on wifi network. Never was a problem on my old 1043nd (19.07.2). But it is a problem with new acrcher C7. If this is something that cannot be configured in right way let's forget it. But I am pretty sure it used to work before
