I have an Airport Extreme base station (802.11n/g) and I use an Airport Express (802.11g only) to extend the network throughout my apartment as part of a WDS bridge. Most of my devices connect to the Express just because it's closer, but I don't get great reception anywhere (thick brick walls). If I replace the Express with a newer "n" enabled version, would there be any benefit in range to my "g" devices?
I guess what I'm asking is if "g" devices can connect to the Airport Express, which then in turn connects to the base station using the superior "n" standard, like this:
iBook ---> ( 802.11g) ---> Airport Express ---> (802.11n) ---> Airport Extreme
...or if the device is "g" only then does the connection have to remain in the "g" mode all the way back to the Airport Extreme base station?
I'm assuming that the "n" standard would have a greater range and signal strength than my current "g" network. I hope my question makes sense!
