** Package changed: network-manager (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/889110 Title: macbook pro 6,2 wireless very unstable Status in “linux” package in Ubuntu: New Bug description: Wireless on MBP 6,2 is (and always has been) very unstable. Wired, there is no problem. When I do 'tailf /var/log/kern.log' I get many retry's with (what seems to me) debug info or memory dumps. At home (with one access point instead of the university roaming network), wireless is 95% stable, but since I saw these 'dumps' in the kern.log file, I thought it might be a software issue anyway. It now can take several minutes before a successful connection is made.
