Today my ADSL was down, so I was using Bluetooth to connect to my phone for extended periods. Twice the connection Bluetooth connection just dropped, and no Bluetooth icon was found in the tray. Neither was any Bluetooth device present in Device Manager. I reinstalled the Bluetooth software from the Dell CD that came with the machine, and it worked for a few hours more, then down, again. Restartng the machine doesn't help, nor does killing the BTTray.exe process and starting it again.
Any ideas anyome?
I'm running Windows 7 Home Premium
