Comment 43 for bug 292450

I have an hp laptop with broadcom 4321 a/b/g/n mini-pcie module and wl driver.
when i first turn the computer wireless works great but after some time i start to get this message and wireless becomes very unresponsive (very high latency) or non responsive at all .

#dmesg

[ 3697.456749] TKIP: RX tkey->key_idx=2 frame keyidx=1 priv=f4606540
[ 3700.983579] TKIP: RX tkey->key_idx=2 frame keyidx=1 priv=f4606540
[ 3701.102287] TKIP: RX tkey->key_idx=2 frame keyidx=1 priv=f4606540

[ 3703.322491] TKIP: RX tkey->key_idx=2 frame keyidx=1 priv=f4606540

I also noticed that this driver also displays some strange results concerning tx power, much higher than it should (can this be why i've read that ubuntu kills broadcom wireless cards ?)

#sudo iwlist txpower

eth1 2 available transmit-powers :
   0 dBm (1 mW)
   25 dBm (255 mW)
          Current Tx-Power:32 dBm (1496 mW)

also i can not set this driver to activate the European extra channels 12 & 13 with adding

options cfg80211 ieee80211_regdom=EU

to /etc/modprobe.d/options

even though this activates a/n features in wireless it looks like a very chity driver from broadcom guys. didnt try other drivers for this wireless card

this is very annoyng

if i use an external usb wireless pen with zydas chip, wireless works great but sometimes crashes X when it is activating

thank you
