Thak you normis, but I have a question and my example...
Is not a repeater, is a Client with an IP (wireless) and a AP, with new ip, and all the firewall rules in the mk....
It isn't just a repeater it's full working parallel Client + AP mode. I think, MKT guys just called it so to make it clear for masses.
You can use the
Repeater Setup tool, and then change they SSID's and bridge/unbridge these interfaces arbitrary. Or you can just add
VirtualAP interface (with it's very own SSID, security profile, lan or address) upon physical
Station mode wlan interface. And, just saw it, you can make it vice versa cause there is
Virtual Client interface!
So update your RB to the 6.35 + repeater package and add a virtual client interface over the physical wlan, configure it as fallback gateway and you're ready. All you have to do is to enable AP on the phone then bad weather going.
I have a similar internet backup config on my open-wrt. And now we can have it on our RBs which is nice.
