Speed and coverage great - when it works. Extended features flaky.
Was very easy to set up as a replacement for the Vodafone router. LAN and WiFi speeds are great. However - will refuse to deliver data to WiFi devices sometimes, even though it's showing as a solid connection. Cannot get it to block any services using firewall rules. Parental controls sometimes go rogue and block access outside of the times specified. Sometimes not all Internet is blocked during "outage" hours. Awaiting assistance from ASUS. Will update review if it turns out I failed to read the manual properly.
