I am seeing this problem as well (using wl module).
from lspci -vvnn: 03:00.0 Network controller [0280]: Broadcom Corporation BCM43225 802.11b/g/n [14e4:4357] (rev 01)
By deinstalling bcmwl-kernel-source, the brcmsmac module activates and I can access channel 13. However, the connection seems to drop a lot and (for example) I cannot watch youtube videos.
