Quick background: I installed Linux Ubuntu 12.04 on a Dell Inspiron 3520 after uninstalling Windows 8. A friend suggested to do this as opposed to buying a laptop with Linux pre-installed. Everything except the wireless card works.
When I load up the laptop, I see a wireless animation as if it's trying to locate the wireless connection (for a while, then it goes blank), but no connections appear under the wireless option (under "Edit Connections" then "Wireless").
What I've tried: - Doing ndiswrapper. Failed. - Installing a few kernels for realtek. Failed.
