Here's the deal: yesterday I tried to join an 802.11b network that, previously, I had no problems joining. Now, I get the frustratingly uninformative "There was an error joining the Airport network "[network name]." I'm using a 12" PowerBook with an AirPort Extreme card. The WAP I'm trying to connect to is a Netgear router. However, I'm pretty sure the hardware isn't to blame; the connection worked perfectly a day ago, my brother's iBook can still connect, and I have the same problem trying to connect to other nearby networks.
So, I'm thinking it's a software problem. I'm running 10.3.4, with Airport 3.4.2. A few of my more computer-adept friends looked at all the logs yesterday, and determined that there was a "lock" in place that shouldn't be... or something. I should have written down exactly what they said. Needless to say, I'm looking for a fix that won't require an OS reinstallation.
So, please help. I'm getting sick of this 4-foot ethernet cable. It's a poor replacement for wireless freedom.
Thanks in advance,
Joe
