I've recently ordered a Dell TrueMobile 300 bluetooth adapter from dell for my inspiron 600m. I have succesfully installed it with the latest driver and got it running. The problem with it now is that my PC seems to be slowing down with the bluetooth switched on. Even playing a song in winamp will have some lag for a second or so frequently. The song seems to jump a sec or two with bluetooth switched on. This goes same with video playback. The bluetooth is working fine connecting with my handphone but i'm very frustrated with the lag. When i eventually turn off the Bluetooth (Fn+ F2) this problem goes away! so i can assure this is a problem with the bluetooth. I have tried reinstalling the driver but am facing the problem. I have also tried using the original Windows XP driver (plug and play drivers) but am facing the same problem. The only way i can solve the problem is to switch off the bluetooth. Does anyone face this problem? How could i solve this problem? Any help would be much appreciated! Thank you.
