13.10 BCM4313 network problems after update

Question

I have a problem with my network adapter after upgrading from 13.04 to 13.10. The adapter works for literally several seconds after I establish the connection but then it looks as if it got clogged somehow.

This is what I see amongst my devices:

~$ lspci | grep -i wireless
02:00.0 Network controller: Broadcom Corporation BCM4313 802.11bgn Wireless Network Adapter (rev 01)
~$ uname -a
Linux bubek 3.11.0-12-generic #19-Ubuntu SMP Wed Oct 9 16:12:00 UTC 2013 i686 i686 i686 GNU/Linux
~$ lsmod | grep 80211
lib80211_crypt_tkip    17387  0 
lib80211               14040  2 wl,lib80211_crypt_tkip
cfg80211              401436  1 wl

Now, how does is behave. Let's assume I connect to my wireless network and straight after I get connected I ping the default gw:

~$ ping 10.1.0.1
PING 10.1.0.1 (10.1.0.1) 56(84) bytes of data.
64 bytes from 10.1.0.1: icmp_seq=1 ttl=64 time=226 ms

From 10.1.0.16 icmp_seq=45 Destination Host Unreachable
From 10.1.0.16 icmp_seq=46 Destination Host Unreachable

What has happened over here? Is there any possibility I can get it working? The only way I could write that post was that I used my phone and USB tethering :)

Thanks for any tips in advance!

Solution

Please try:

sudo apt-get purge bcmwl-kernel-source
sudo modprobe -rv wl
sudo modprobe -v brcmsmac

if there are any errors please continue with the commands then reboot. your wireless should be working now.

Also, you should probably report this as a bug in launchpad so that it can be fixed.

Thank you. This solved my problems with BCM4313 wireless on an Asus laptop after I updated it to Ubuntu 13.10 and the wireless stopped working with some hotspots (newer ones, I assume, as it worked with an old wrt54).
