After upgrading to 12.04 LTS, I am seeing TX errors popping up in
ifconfig. I am using a Broadcom4313 wlan controller.
lsmod | grep wl gives:
wl 2646601 0 lib80211 14040 2 lib80211_crypt_tkip,wl
The wlan is connected but the speed is less than 10 KBps.
Capabilities: Speed: 1Mb/s
But my net connection is 15Mbps !!!
