Hello all,
i recently updated my Ubuntu from 12.10 to 13.04, The problem is when ever i restart my laptop i am unable to connect to internet. So what i do is i install "bcmwl-kernel-source_5.100.82.112+bdcom-0ubuntu3_amd64" from installation cd, every time i reboot.
is there is possible permanent solution for this?

Hi Archit!

Please post output of :

Code:

lspci -nn | grep 0280

If it is "..... BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] ...", then try this post : http://ubuntuforums.org/showthread.p...9#post12629619

PS:
By the way, which installation cd do you install those packages from? Because they are not on my 13.04 DVD, instead a newer version.

Code:

 lspci -nn | grep 0280
02:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01)

pool/restricted/b/bcmwl/bcmwl-kernel-source_5.100.82.112+bdcom-0ubuntu3_amd64.deb

Until driver compilation every thing was alright

Code:

cp wl.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless

my modules folder showing me this

Code:

3.5.0-17-generic  3.5.0-27-generic  3.8.0-19-generic

where to copy?

Hi, it should copy by it's self with the command

cp wl.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless

leave `uname-r` just the way it is, no need to fill in any data.

post back if you have any more errors.

thanks.
