http://ubuntuforums.org – Hi, I updated linux headers from 2.6.28-17 to 2.6.28-18. After i rebooted my notebook (hp dv6646us) its wireless wasn't working anymore. So i went to Hardware drivers and it wasn't listed there anymore either. It always worked fine on 9.04, and was always listed there fine too (Broadcom STA). I am now back using 2.6.28-17 ... But anyone knows a solution for that issue? Cause really, now i am afraid to update as it is inserting bugs while it should be doing the opposite ... (Hardware)
