I have two R8000 routers and use them as AP. Recently, I switched a new modern and my internet stoped working .
Symtoms: I can access some websites, but most websites are not accessiable.
After I reset routers and try many different things, I found I cannot set both routers in AP mode. They will fight each others and cause the symtoms above.
In this case, I removed AP mode from one routers. everything works fine by now (half day). However, I have many devices and they cannot communicate eachother properly without the AP mode.
Router1 (AP mode): Device1, Device2, Device3
Router2 (Not AP): Device4, Device5, Device6
Symtons: The Device4, 5, 6 can take with 1,2,3. but cannot do the opposite way.
If both routers in AP mode, then network will crashed in hours (sometime immediately, sometime not). One group of devices can access website, another group cannot.
