WiFi stops working after a certain time period
Posted: Sat Nov 17, 2012 1:23 am
Hey everyone,
My wifi simply shuts down after a while. The computer keeps trying to connect but is unsuccessful. It keeps asking me to re-enter the password over and over again, but fails to establish a connection. I know its a mint problem because my windows laptop doesnt do that (and neither did this desktop when I had windows).
So the sudo /usr/lib/linuxmint/mintWifi/mintWifi.py results that i got (this is when everything is working fine):

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service smbd reload
Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the reload(8) utility, e.g. reload smbd
