I have recenty installed ubuntu 14.04 LTS 64 bit. My university provides cyberoam wifi connection. After 5 seconds to 1 minute, internet stops working and then wifi disconnects. I have to disable wifi and re-enable to connect with the network again.

lspci

gives following:

Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01)

I have already done this

echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi
sudo sh -c 'echo "options iwlwifi 11n_disable=1" >> /etc/modprobe.d/iwlwifi.conf'

On ubuntu 12.04 and windows, wifi is working fine.

EDIT:

I followed this link
my PCI.ID is 14e4:4365 rev 01 . So Special Case #2 . Tried steps as mentioned but still same problem.

I am facing this problem only on my college cyberoam wifi network. Problem is with ubuntu 14.04 because this network is working fine with ubuntu 12.04 and windows.

  • I am sorry that it didn't work. May be someone else will be able to help you. Please [edit](http://askubuntu.com/posts/609184/edit) your question and add the PCI.ID up there along with the steps you followed from previous answer (put in a link in the question), and errors if any. some people don't go through the comments. – user68186 Apr 20 '15 at 17:10
  • I have same problem. Looks like it's a bug in the driver. Check this thread https://bbs.archlinux.org/viewtopic.php?id=193129&p=2 I'm trying to apply solution for Ubuntu. – Fyodor Oct 22 '15 at 22:00
