[SOLVED] Wireless fails to connect after resuming from sleep
Posted: Thu Jan 03, 2013 11:55 pm
Just installed Mint 14 on my laptop and having some issues with wifi when I resume from sleep. I've spent the last few days searching for people with similar issues, reading logs, but haven't had much luck on my own. I should mention that I've tried this on two different access points, one 802.11G the other .11N and the fore with WPA-PSK, the latter network is open. Here's my mintwifi output:
Here are some solutions I've tried and they've failed:
Looking through logs have revealed only these suspicious looking entries:
/var/log/syslog
/var/log/pm-suspend.log
Seems to be it would be something to do with the system waking up from sleep, but I'm not sure where to start. Any suggestions would be greatly appreciated. Thanks in advance.

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
