I have a Mac Powerbook. Why do I get error messages when trying to join Airport networks?

Question

It even happens with networks that don't require passwords...

Please re-post and tell us what the error messages say.

Then, maybe we can help.

Answer 2

Make sure you have your software up to date. There have been several Airport updates. Also, get macstumbler, it's a freeware program. It does a better job of telling you the signal strength and password protection of wireless networks. Anything below a 30% and you will have difficulty locking in the signal. Also try rotating the Powerbook a bit, because of the metal case, the antenna gets blocked from the signals sometimes.
