Title:
14e4:4727 Broadcom BCM4313 random AP disconnects and network hang
Status in Linux:
Confirmed
Status in linux package in Ubuntu:
Won't Fix
Status in linux package in Arch Linux:
New
Bug description:
Using the brcmsmac driver I'm experiencing random AP disconnects and
network hangs. I can usually come out of a hang by reconnecting using
the network manager. I'm unable to try the STA driver as this appears
to be uninstallable at this time although I would prefer to use the
free driver.
I got a lot of the following in kern.log during the issues

Description: Ubuntu precise (development branch)
Release: 12.04
02:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n
Wireless LAN Controller [14e4:4727] (rev 01)
Subsystem: Broadcom Corporation Device [14e4:051b]
Flags: bus master, fast devsel, latency 0, IRQ 17
Memory at d0400000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: brcmsmac

My main workstation is also running precise with an Atheros 802.11n
card and various other wifi devices that work fine so I'm almost
convinced it's not the router which is a BT Home Hub v3.0
Please let me know if you require further information.
