This is the right place to ask. The driver you are using is from staging, and I
don't know much about it, but let's see what we can do.

Please provide the output of the command '/sbin/lspci -nn | grep Realtek'.

In addition, please post the output of the command 'sudo /usr/sbin/iwlist scan'.
I'm guessing at the location of iwlist on your distro. If the command is not
found, then the patch is wrong - change it to match your system.
