t420 my wifi not enabling

I am currently running win7 x64 on the t420 with the Intel(R) Centrino(R) Ultimate-N 6300 AGN. Now when I first turn on or restart my computer, the my wifi works perfectly. It allows me to create the PAN and connect up my desktop(send files from laptop to desktop). The only issue I have is that if I run the computer for a few days or I enter sleep/hibernate and resume windows, the my wifi does not work, however the regular wifi does. In other words, I am no longer able to create the PAN but still have internet access. Anyone else have this problem? I have tried everything, that includes flipping the wifi power switch, disabling and restarting services, disconnecting and reconnecting from my normal wifi connection, enabling and disabling wifi through software, but nothing short of a restart seems to bring the my wifi PAN connection back to life. If anyone has any insight it would be grealy appreciated. I'm using the intel proset software provided by intel(its up to date) because the lenovo version would crap out from time to time. I believe the lenovo driver version also had this problem.
