Hey, I have an airport express, one of the ones before the n spec, and every few weeks it needs to be unplugged and replugged in in order to work. The modem is fine, all the macs are asking for a new password, even though the light is green... it still just requires to be unplugged and replugged in to get it working properly again. Is is just getting old? Is there a setting i can fiddle with? Thanks, r.
