do this one:
disconnect network when idle for 1 min
HKLM\Comm\CommMgr\Planner\Settings\
set "SuspendResume" to 58 00 00 00 33 00 99 00 88 00 39 00 58 00 39 00 29
add "CacheTime" value of 60
works awesome, i use it, and it disconnectes you from the network when your not using it.

oh and it solved the problem i had where i couldnt answer phone calls when i was connected to the network. it works good. when your connected to the network and you get a phone call. you will hit "answer" but it will take a few seconds for it to disconnect to the network and pick up the phone call.
