Postby Zavulon on Wed Feb 13, 2013 4:12 pm

Hello,

I have a Dell XPS 17 (Jan 2012) and following is output from mintwifi:

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

Ii seems power management problem, hibernation or much downtime can turn off the wireless, look at this.

Disabling power management seemed to solve the problem.

But I was wondering, I only found to disable power management on wifi, but can you tune power management instead?

I think Yes, look for power management on your netbook, now I'm using PC that does not have this option.
