I have an old C7v2 to that was the basis of my household's network until I upgraded to an EdgeRouter + Unifi APs. The C7 was fine for a while but in the end got extremely unreliable, even in partial roles as only a router (with wifi disabled) and then later as only a an AP (with the DHCP server disabled). Currently it's unplugged because any time it was turned on, devices would roam to it and get stuck there with no connectivity. I should try upgrading it to the latest OpenWRT and see if things are any better.
