WIFI and Hell

For lack of time, the gist of this whole affair is described as follows: if you have a Realtek Wireless Card on your computer (most probably, on your laptop) and your Linux distribution doesn't seem to play well with it (no WIFI, connection drops randomly after a few minutes, etc), go ahead and do this:

1. Clone 'rtlwifi_new' package from GitHub -- these drivers are polished and work much better than the ones built in the kernel
2. make
3. sudo modprobe -rv rtl(driver)
4. sudo make install
5. sudo modprobe -v rtl(driver)

In my case, my WIFI card is the model RTL8821AE, so the driver's full name is 'rtl8821ae'. God bless the Holy Open Source brotherhood of programmers!
