My MacBook Pro's Airport Extreme card usually recognizes ~15 wireless signals (I live in an apartment building), now it picks up none. If I try to manually access my own wireless network (which works fine for my flatmates' computers), it says "There was an error joining the AirPort network". It doesnt seem to care that the network normally has a password, it just gets an error. Max OS X v 10.4.11 AirPort Extreme firmware version 1.4.4 maybe it's just broken? if anyone has any insight i'd sure appreciate it!
