[Bug 1432659] Re: HP Pavilion 13-b208tu w/ Broadcom BCM43142 Wifi unstable, panics
Router firmmware has been updated, although I don't think that can help
us diagnose the fault.
I wasn't able to reproduce today through normal use, but am able to
trigger a failure using suspend/resume. Is this the same bug, and maybe
a pointer to an ultimate fix?

Title:
HP Pavilion 13-b208tu w/ Broadcom BCM43142 Wifi unstable, panics
Status in bcmwl package in Ubuntu:
Confirmed
Bug description:
This new laptop's wireless connection (HP Pavilion 13-b208tu, Broadcom
BCM43142) is disconnecting every few minutes. This corresponds to
panics and tracebacks in the kernel log.
The laptop was freshly installed with Ubuntu 14.10 (Utopic), and
disconnections were seen. I then upgraded it to Ubuntu 15.04 (Vivid
developement release), and am still experiencing the problem. The
Broadcom proprietary driver is being used, and seems to be the only
one available for this device.
