you could update your JVM to 1.5.0_07 as it is as far as I know recommended for Wifi 3.0.
It is usually a problem within the JVM or within some native libs (pam, trayicon, …) which you’'ll find in the hs file.
Sun recommends to use the latest java version as a lot of exception / segmentation faults are claimed to be managed much better with the latest version.
And you could of course post the content of the hs file so one can look at this problem you see.

I have upgraded Wifi to 3.0 on Wednesday and i think i dont have 07 java (will check this later). Was working, though only few people were connected after upgrade.
