We have a shared WiFi network for our hostel. After I upgraded to 14.04 that particular WiFi network is not getting listed in Ubuntu (other WiFi networks are listed and am able to connect).

However I'm able to connect to that same shared network with Windows on the same laptop. What could be the possible reason for only that WiFi network not getting listed?

I performed an iw reg set IN to set it to India.

The output to lspci -nn | grep 0280 is:

12:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11bgn 
Wireless Network Adapter [14e4:4727] (rev 01)

I performed scan for the network using iwlist scan . The network i want to connect to is not in the list but at the same time it is available in my mobile and other laptops near by.

First, find out which driver is installed:

lsmod | grep -e wl -e brcmsmac

This: Installing Broadcom Wireless Drivers suggests that the correct driver is brcmsmac. If you have wl, you will have much better performance with the former. Remove the incorrect driver:

sudo apt-get purge bcmwl-kernel-source

Reboot and let us hear the result.
