This could be caused by power save, which is disable by default
in the driver but some programs/distribution seems to enable
it without user knowlage. First check:
$ iw dev wlan0 get power_save
and if PS is enabled, disable by:
$ iw dev wlan0 set power_save off
and check if problem still happen.

This does not make sense as 3945 device is handled by
iwl3495 (iwlegacy) driver, not by iwlwifi.
