Hi,

since kernel version >= 3.4 wireless became extremely slow (download
rates of about 90k/sec when downloading a new kernel from kernel.org
instead of >1MB/s)https://bbs.archlinux.org/viewtopic.php?pid=1146085

There is a thread on archlinux
https://bbs.archlinux.org/viewtopic.php?pid=1146085 where people observe
the very same. Kernel 3.3.X was the last known good one.

*Sometimes* download rates are OK but most of the time they are not.

$lspci | grep Broad

04:00.0 Network controller: Broadcom Corporation BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01)


Any ideas?
