Hi David,

I've had similar issues with this version of the driver.
Unfortunately, I can't offer you an explanation nor a reliable
solution but what I've found to get it to work is to use the load
script instead of modprobe that comes with the driver distribution
to load the driver, then sometimes I need to run iwconfig eth1 essid
<> a few times to get it to stick.  If that fails and you've been
trying a few things to get it to associate, try rebooting.  I've
found that many times it'll associate right up after a fresh reboot.

I think where things may get messed up is switching from one wireless
network to another and an extra reboot (at least to me) seems to help.

Maybe someone who's more familiar with how wireless works on Linux can
give a more reliable explanation and/or solution?

Thank you very much!
