Hello All.
Newbie with a question I haven't found an answer to.
On a Dell Precision M6300 with Broadcom BCM5756 I did an update from 10 to 11.04.
Prior to the update, the wireless worked fine, now it is non-functional.

I see that BCM43** based wwireless cards are 'supported' and my BCM5756 is not on the
'supported' list.

Does this mean I'm SOL on wireless at this version level? Is there a work around? Should
I wait for 11.04 updates?

Currently I'm looking at a roll back to 10 but if someone has a solution, I'd sure like to re-up to
11.04.

Thanks
