I have an Airport Extreme connected directly to the internet and in another part of my house an Airport Express 802.11n. It is an extended network and works fine. (most of the time) I have some tenants in another part of the house and they are getting a weak connection from the Base Station. I want to use an older 802.11g Airport Express I have lying around to extend the network into their area for stronger signal strength. A short term solution until I hard wire something there. The thing is, the AEp 802.11g does not have an option for extending a network only joining a wireless network or participating in a WDS network. The firmware on the unit is 6.3. The 7.6 firmware seems to be only for "n" wireless devices. I set it up for joining a wireless network and plugged it in next to a laptop in the apartment...nothing. No boost in signal strength at all. What am I doing wrong?
