AE 5th Gen 2.4GHz Won't Connect

I have an Airport Extreme 5th Gen with 7.6.1 software.  It's always seemed a bit temperamental to me so when devices could not join the 2.4GHz network today, I decided to do a hard reset and re-enter settings.  Unfortunately, that didn't fix it: devices that formerly were able to connect on the 2.4GHz 802.11g are now unable to - I just get a 'connection error' message.  The 5GHz 802.11n side continues to function.  I need g for those devices that can't connect to n.


I have the Airport Extreme connected to a cable modem and it is creating the wireless network(s).  Although there are a couple of Airport Expresses connected to the network, these are only used for AirPlay and I have turned them off for the purposes of testing.  The networks are named differently and use automatic channels.


It occurs to me that the 2.4GHz problem could be due to interference, but I would appreciate a second opinion please.


Has anyone here encountered this kind of problem where the Extreme itself is faulty?  I have AppleCare, so could take it for a check at an Apple Store.


Any help would be greatly appreciated!

    Hi - you probably already know this so I am just speculating here - since the AU defaults to include g devices, it sounds like you might be having a security issue - the AU defaults to WPA2 Personal - are you able to match this with your g devices? - WPA/WPA2 Personal is more compatible if you can't do WPA2 Personal - see the following password equivalents if necessary - I always use simple 8 character passwords for compatibility.

    The AU also defaults to a WPA Timeout of 60 Minutes - this can be an issue with older devices and security types - some people set it to a higher number but this might make your network more vulnerable.

    If the above does not apply then I would have the Extreme checked out.
