BCM4312 stuck at 1-5 Mb/s

[Tamakizu]

i installed the firmware with fwcutter information provided in my dmesg it works pretty stable just at very slow speeds. If i'm really close to my access point i'll get 5Mb/s and if i move rooms it's usually at 1Mb/s.

I had the same problem with a broadcom 4318, a recent update (kernel upgraded to 2.6.24-17) fixed this problem for me, hope it was fixed for you too.

Glad it is fixed for you now i must confess i decided to reinstall on release date and this time did it with ndiswrapper which worked for me so i cant confirm.

I have the kernel 2.6.24-17 and l still have the same issue. I'm only getting 1mb from my wireless. This problem have been going on for a long time, is not one going to fix it? I've read dozens of posts that go back for months. Please fix this guys. Thanks.
