Laptop can't communicate with Airport
My main issue with this is that I can no longer stream music from the laptop to the Airport - iTunes cannot find the Airport either.
When I did a factory reset of the Airport, it showed up in Utilities again - but when I try to configure it, I get an error message (error code -4).
I CAN configure the Airport (and send iTunes music to it) with my other computer, also a PC but a stationary one. It is connected with cable to the same router as the Airport. Both computers have Vista and the same versions av iTunes and of the Utilities program.
I tried plugging the network cable that normally goes into the stationary computer into the laptop - but no go. The result was the same, Utilities can't find the Airport.
So the problem sure seems to be in the communication between the particular computer (the laptop) and the Airport. I tried turning the Windows firewall off, but it doesn't help.
Any ideas what could be wrong? Like I said, it worked fine until a week ago. I think the problem started after an iTunes upgrade, but I am not 100% about that.
Any help would be much appreciated! Thanks!
