    Post bcm4306 performance

    I'm new to ubuntu, but not to *NIX. What brought me here about a week ago, is a final attempt at a functional wireless linux laptop. Failure meant giving in to the darkside, MicroSnot, and my old laptop's eventual death by bloatware... My preferred distribution of linux is Slackware, a decision made before ubuntu was thought of... Having previously failed at getting an Intel miniPCI ...11g working, I have since upgraded the miniPCI to a BCM4306. I did the fwcutter thing with no luck and more research led me to believe I needed to try NetworkManager. That meant significant effort with KDE & Slackware. Rather than do that I thought I'd see what the rest of the linux world was been up to. I eliminated a few other distributions for various issues and decided that unbuntu looked the most promising.
    After installing 8.04 desktop, I copied my b43 drivers and things looked promising but not yet functional. As soon as I turned on NetworkManager, wireless came up and connected with WPA. Part of exploring the minor variances of GMOME vs KDE, I soon discovered that the BCM4306 was capped at 1Mbps. After reading many tales of wireless woe here, I didn't feel as bad since my wireless is actually working, even if it's slow. While 1Mbps is OK for the average cyber-cafe, it's a irritant at home with 10Mbps Internet and the amount of file sharing I do... I've tried various things to bump the speed, but most result in non-functional wireless or even slower throughput.

    So finally the question... Is there any hope of getting the BCM4306 up to speed or should I just give up on a fast internal wireless solution for this laptop? I could switch back to the Intel ...g on ubuntu, that should at least give me a tick over 5Mbps, but still too slow for my home usage...

    If you have no problems with using NDISwrapper, that would be another option. Did you try to adjust the speed through iwconfig rate?

    yes, I tried combinations of 11M, 54M and auto. In some cases the throughput is slower, others it simply stops working even though is says it's connected.
