Comment 17 for bug 775281

Same problem with Dell XPS 16 and Dell Studio 15. Got wifi working again by uninstalling Broadcom driver in "Additional Drivers", rebooting, and then reinstalling Broadcom driver. Sorry - I am not very technical but thought my "fix" may be of interest as it was not listed previously. I did not have this issue on the two machines prior to 11.04 (cat walks across the keyboard all the time).
