For about 8 months, I have been teathering my BlackBerry Storm2 to run my home computer (Windows XP). I recently bought a new computer with Windows 7. It will occasionally run at 3g speeds, but most of the time it doesn't. I spoke with tech. support several times and got nowhere. Is there anything I can do to get back my 3g speeds or is there a solution coming soon? Any info would be greatly appreciated.
