Using an Airport Express as wireless repeater
I have recently bought a new Netgear N900 (WNDR4500) router but like my old router, I still have a weak WiFi signal towards the rear of the house so I have looking into WiFi range extenders/repeaters. Most repeaters I've looked at (including a Netgear) rely on WiFi to connect to the main router which I don't really want. We have an Ethernet switch already situated in the back room so I ideally want a WiFi repeater to connect to the main router directly via Ethernet.
The Apple Airport Express appears to allow this type of connection though "roaming networks" according to Apple's website but I cannot find a straight answer as to whether it'll work, using this method, with non-Apple routers such as my Netgear.
Can anyone advise as to whether I can extend my Netgear router's WiFi range with the Airport Express connected to it via Ethernet, keeping the same SSID, password, etc?
Thanks in advance for any advice.
