Hi,
I am new here exploring if I can use NanoPi M4 as a router+access point using its 5Ghz WiFi for other clients to connect to.

Are there any better recommendations than NanoPi M4 ?

I want to set up a few features on the router:

1- Wireguard
2- PPPoE
3- 2.4Ghz & 5Ghz WiFi
4- AdGuard (Does FriendlyWrt offers this ?)
