Subject: Re: BCM4313 & brcmsmac & 3.12: only semi-working?

Hi Arend,

sorry for my late reply, it took me a bit to get the modules compiled with 
your patches. Here is the information from my card. During this test I had 
very bad performance with my wifi connection with big latency and lots of 
packet loss.
