gd, i have mbp pro mid 2010 a1286 2,66 ghz i7. everything always worked fine with airport antenna but today i had issue. we went out with some friends out @ place w/ wi-fi. THE THING IS everybody had a signal except my mbp. i restarted the computer in windows, the same - it can't c the network, even i'm preety close to router. i got curious and tried my iphone. it could find this wi-fi hotspot @ 3 full bars and connect with no problem. even phone can connect but MACBOOK PRO can't ? well i have KisMac on my mbp, i ran it on my airportcard in active mode - nothing happens. passive mode - he can c the network with good signal but apparently can't connect because of passive mode. wtf ? any solution for this problem or it is hardware failure ?
