Are you suspending during that time?  What driver are you using and what
wifi hardware do you have?  Do you see the messages "sleeping..." or
"waking up..." in the NetworkManager logs in /var/log/daemon.log
or /var/log/NetworkManager.log?

NM scans at *most* every 2 minutes unless it's been altered by the
distribution.  Your case sounds like either stupid drivers or a
well-known-but-supposedly-fixed D-Bus bug with the suspend/resume
scripts.

- if you see sleeping/waking up in the logs then it's likely a driver
problem
- if you dont' see sleeping/waking up but you do see other NM messages,
then it's likely the d-bus thing which we can further diagnose.
