For a week I can’t use my wireless. This problem makes me installing fresh Ubuntu Karmic Koala in my lapie for 3 times, sadly
.
First of all, if your system same as my own, just try this trick. But if different, hmm, try with google
.
I found this trick from Ubuntu Forum posted by chenxiaolong, thanks chenx, you save my lapie.
So, open your terminal, and check your wireless first :
lspci | grep Broadcom 03:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)
If your wireless looks like that, let’s continue :
#install linux backport : sudo apt-get install linux-backports-modules-karmic #blacklist ssb module : sudo echo "blacklist ssb" | sudo tee -a /etc/modprobe.d/blacklist-ssb.conf #blacklist wl module : sudo echo "blacklist wl" | sudo tee -a /etc/modprobe.d/blacklist-wl.conf #restarting your system : sudo reboot
That’s all, after restarting, enjoy your wireless ![]()
