Hi folks, at the moment I can only source my Internet at home via WiFi as opposed to normal LAN cable … how can I use (configure) the Omnia so that it still behaves as my home router?
First off all do you have turn on wifi on the router ?
Well you can try to use google as it is actually very easy to do with LUCI web interface.
It is described in plain english here https://openwrt.org/docs/guide-user/network/wifi/relay_configuration
Needless to say there are another option to use mesh network with more wifi AP involved but you need to configure a bit more. Described here https://openwrt.org/docs/guide-user/network/wifi/mesh/start
