A: I have a question of my own: Why are you still on Ubuntu 12.04? There is no reason to be. Rather upgrade to 18.04 and enjoy the benefits. If you have an application that runs only in 12.04, use Virtualbox and install 12.04 in there. The problem with VLC on Ubuntu 12.04 is, if you want the latest, you will need to build it yourself. Ubuntu 12.04 no longer receives any updates. | A: I have a question of my own: Why are you still on Ubuntu 12.04? There is no reason to be. Rather upgrade to 18.04 and enjoy the benefits.

A: Most Lenovo laptops are made for Windows only, and Lenovo locks down their BIOS's so that you can not install a friendlier Linux-compatible WiFi card. Restarting the laptop or WiFi router will solve the issue. If your laptop accepts a proprietary driver for WiFi, use that. Should you have the proprietary driver installed, uninstall it and test. You could alternatively also replace the Wifi card with a decent one, just do your homework first. | A: Most Lenovo laptops are made for Windows only, and Lenovo locks down their BIOS's so that you can not install a friendlier Linux-compatible WiFi card.
