Hey folks,
I'm having issues with WiFi on my Macbook Air 6,2. I'm able to connect using both the broadcom-sta-dkms and bcmwl-kernel-source drivers (hooray!). When I first connect, I have the same speeds as I get on OSX (20-50mbps), but after about 30 seconds of being connected, the speed drops off to 1-2mbps and stays there.
I've tried many things: different drivers, disabling power management, using WICD instead of network manager, turning off IPv6, disabling 802.11n, but the problem persists. I really hope I can find a solution as 1mbps means no more Ubuntu
Here's the wireless-info output:
