I have also tried upgrading from 3.13 to 3.18 kernel. It did not solve the problem.
After going through a lot of articles, today saw this bug, and the workaround given in tlue's post. I have tried it now. Wifi is up from last 22 minutes. I will update here after using it for sometime. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1297286 Title: Wireless connection keeps disconnecting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1297286/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
