Fedora 13 - Can't Access Wireless Network


Hello,

I got a development machine with Apache installed. Everything was configured correctly, machine was running perfectly for some time, but today, suddenly I lost connection to my Wireless network.

Now I simply...can't access it. All details are correct, I even turned off MAC Addresses validation to make sure it's not my AP configuration fault. Nothing helped.

Any ideas what could happen? I did not update any libraries/packages. Just got disconnected from my network and cannot access it anymore.

To give more informations: I'm using Broadcom wireless device and b43 driver but I don't think this can be an error. Logs tell me nothing.

This isn't exactly your problem, but sounds similar enough to a problem that I saw on a wired network. The network was configured for DHCP. A 24-port switch was being used to connect approx 10 computers (which were being purchased along with the switch).

Before the Acceptance Test Procedure started, the switch was isolated from the company's network. For two days of testing everything worked properly. Then everything downstream of the switch stopped talking on the network.

The problem turned out to be "expired" IP addresses. One by one, the hosts (connected to the switch) tried unsuccessfully to renew their network addresses... only to find that they couldn't communicate with the domain name server (upstream from the switch).

Running WireShark on your Fedora box might shed a clue.

I was trying to analyze it for few hours, without any success.

When I try to connect this network (btw. it's not visible on the list, I had to add it manually) after few seconds it prompts me for WPA password.

In /var/log/messages I can find:

Basically, it tells me nothing. I also tried to disable WPA in my AP Control Panel, still does not work. Maybe someone of you guys will be able to see something important in this logs.

Of one more thing, it does not matter if I use DHCP or not. Still no connection.
