Improve wifi reliability after resuming from suspend

Browse source 
Using the old script I regulary	had the	problem, that after resuming
from suspend (or hibernate) the wifi would just break. The only way
to fix it was to restart network manager, or disable it in the GNOME
network settings.

I am not a 100% sure *why*, but this change greatly improved the wifi
stability after resume. I am running this for like 5 days now and
didn't see the wifi breaking once. I suppose, that `modprobe` vs
`modprobe -i` is what makes the difference.
