I have been experiencing this in both 13.04 and 13.10.  My desktop
computer has a micro usb Belken N300 wireless adapter and if there is no
constant activity the network stops responding.  If I reselect my
wireless SSID it will reconnect and the network regains traffic until
the activity stops again.  I have found leaving streaming data in the
background, like large ftp file transfers, has been my temporary
solution.  Happy to help out where I can but I'm not sure where to start
looking.

I have tried changing my wireless channel, turning off IPv6, forcing
static ip and dns.  Any help is greatly appreciated.
