Go to network icon, select Edit connections, delete the settings for your wifi network. Then try to reconnect to create new settings. Or do sudo rm /etc/NetworkManager/system-connections/accesspointname and reconnect . Same thing – Sergiy Kolodyazhnyy Aug 8 '15 at 18:04
    
@Serg, I tried this option, but its giving the same problem again – naman arora Aug 8 '15 at 18:11
    
OK. Well, I guess we can go a bit further with this - run the diagnostic script, link the results here, and we will see. – Sergiy Kolodyazhnyy Aug 8 '15 at 18:18
    
Hi, I ran it, it just shows ########## wireless info START ##########, nothing else – naman arora Aug 8 '15 at 18:33
    
This is not right. Run it again. Follow the instructions. You should have info about your wireless card, drivers, and connections listed bellow that line – Sergiy Kolodyazhnyy Aug 8 '15 at 18:51

I believe the incorrect driver is installed. With a temporary working internet connection, open a terminal and do:

sudo apt-get purge bcmwl-kernel-source
sudo apt-get install firmware-b43-installer

Reboot and let us know if the performance has improved.

Exra credit, by the way, for posting the wireless script on Microsoft Drive!
