People do care, it's just that time is limited, and people are busy. Whilst nobody has provided this advice, the usual "My device doesn't work and I'm not using the latest version of the driver" / "My device doesn't work and I'm using my own patches" advice is to use the bleeding edge Compat Wireless, without any extra patches, and see if the problem can be reproduced with that. See here: http://linuxwireless.org/en/users/Download Compat Wireless is the current wireless stack re-packaged to be compilable on older kernels. Give it a shot, tell us if it works.

After this warning I can't connect to an AP anymore, I have to unload and reload the brcmsmac module. Thanks for your time. -- Francis ^ permalink raw reply [flat|nested] 9+ messages in thread
