I don't like USB wifi at all. the antennas are tiny and have very poor gain or efficiency. you want to get an internal mPCI-E card or whatever it is your laptop expects, as that will connect to the built in antenna which runs along the top of the screen on most laptops and will give you FAR better signal gain resulting in better range, and faster transfers -- john r pierce, recycling bits in santa cruz ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Every time I encounter big enough trouble about some chipset to have to learn a bit about its internals, I usually learn about its engineering flaw. BCM43xx has the following one: the chip internally is 32 bit, though it sits on 64 bit bus. (Take that with a grain of salt, it's been long time since I looked into that crap). Once I discover the flaw, I add particular hardware in my black list and do my best to not buy anything containing it. Broadcom as a whole is not in my black list, they have great hardware, but their BCM43XX is, even if they corrected their design flaws since. I would replace that if possible (Intel would be great candidate), or use USB adapters others suggest.
