[Kernel-packages] [Bug 1069766] Re: 14e4:4331 Slow transfer speeds with BCM 4331
Jussi Pakkanen / Seth Forshee, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If it remains an issue, please just make a comment to this. As well, as a potential WORKAROUND, would the Broadcom drivers provided via https://launchpad.net/ubuntu/+source/bcmwl provide improved performance? ** Changed in: linux (Ubuntu) Status: Confirmed = Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1069766 Title: 14e4:4331 Slow transfer speeds with BCM 4331 Status in “linux” package in Ubuntu: Incomplete Bug description: The BCM 4331 wireless chip has slow transfer speeds compared to OSX.
