It is my first Wifi Router. I to be able to have both 2 & 5Ghz band
I struggled a bit at the internet connectivity at first, and I'm just wondering why I was not able to change the LAN IP address range ...
So I don't know if it is a bug or what I did wrong : but when I tried to change the Address range of my Archer C7 , It did not want to change (using LuCi interface)
Network → Interfaces → Edit → 192.168.2.1 → Save and Apply => Failing
Hopefully for me my DSL modem were easier to move to 192.168.2.x
Note : I figure out the solution after investigation (I agree I'm a newbie), thanks to Troubleshooting hint : https://openwrt.org/docs/guide-quick-start/ts-internetconnectivity
