The same here, "Error sending C_SCAN: enqueue_hcmd failed" and "BSM uCode verification failed at addr" and all the other niceties, for this good ol' piece of hw that have been working flawlessly under other OSes, so it's definitely a sw issue.
I don't really hope for getting a solution, but anyway, won't hurt to mention. Additionally, if you let me comment on the issue policy here: * this bug has been reported more than 2.5 years ago * it affects several Ubuntu versions * it affects a lot of users (more than 54, just not everybody registers for adding a 'meetoo') * it makes the OS virtually unusable (i know, still can ping localhost, hooray) * nobody has taken any steps to solve it, *not even asking a fine question* * the ticket hasn't even been assigned to anyone * and its importance is still 'LOW' That last word 'LOW', my dear Sirs, is the exact quality of the support here, not because of the lack of success solving the problem, but because not even being interested in trying to. Since this OS is free, I got exactly the worth for my money, so I don't complain, but whenever I'll happen to need *paid* support for some company IT business, hell sure that it won't be Canonical whom I'll contact in the first 100 place. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1408963 Title: [Xbuntu 14.04, 14.10 and 15.04] Network manager stops working: iwl3945 0000:03:00.0: BSM uCode verification failed at addr ...; wlan0: deauthenticating from... by local choice (Reason: 3=DEAUTH_LEAVING), Status in network-manager package in Ubuntu: Confirmed Bug description: From time to time, the system loses all wireles networks and kubuntu network manager applet goes blank - not even one network is shown.
