Sadly, yes, it is a BCM4318. I've tried moving further away from the AP, as well as decreasing the txpower output.. neither seemed to help any. I suspect something else may be the cause of the poor performance that I'm seeing. I'll try to rule out the card as a problem tonight by setting up an Ad-Hoc network under Windows XP. If I observe good performance then maybe b43 is the issue... In which case.. I'll start the painful process of comparing the Windows driver to b43. If I find any discrepancies, I'll send them to the reverse engineers to be posted with the rest of the specs. Then maybe you or someone else can make the appropriate changes to b43.
