Bluetooth keeps crashing on Dell Inspiron 1545

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

First step is to download and install the latest Bluetooth driver from Dell.
In this Support page you will find, under Network, the module "Wireless 365 Bluetooth Module", dating from december 2009. Download and install.

Then run Windows Update and see if there is any optional (or non-optional) update that relates to Bluetooth. Install if found.

Reboot a couple of times and check if the problem persists.
If it does, then further steps may be called for.

By the way, is the laptop still under warranty?

EDIT

The article Fixing Intel Wifi Link 5300 AGN Drop on Dell Latitude E6400 contains some advice that you should look into. The most useful recommendation is apparently to disable Bluetooth from the BIOS, which doesn't prevent Windows from using the wifi card but keeps the BIOS from interfering.

Yes, it is still under warranty, I would just like to avoid taking it in and being without it for any time if possible. – ProfK – 2010-10-05T14:58:48.660

Have you done everything else I described? – harrymc – 2010-10-05T15:25:49.567

Yes @harrymc, I found the latest BT driver package on my machine, it had recently come down via a Windows update. I tried a manual install of the driver as well, to no effect. I still lose the BT connection at random times and need to restart. – ProfK – 2010-10-22T04:26:00.263

Have you tried with multiple bluetooth devices? Like a headset or mouse/keyboard? It could be related to the specific device you're connecting with. – Adam – 2010-10-22T04:35:41.083

@ProfKaos: I edited in some interesting advice I found. – harrymc – 2010-10-22T06:12:00.303

@Harry, I only have the one BT device, my phone, which I do actually also suspect, but I've never known Nokia to give problems in this area. It is however a lower end phone, so maybe. – ProfK – 2010-10-23T05:32:30.527

I last used BT 6 months ago and my BT icon is still in the tray. I wonder if the icon is set to always show or only when notifications? – harrymc – 2010-10-23T07:59:42.097

@harrymc, it's set to to always show. I've checked that multiple times. I'm going to borrow a phone and compare the robustness of the link with that phone. Otherwise I must suspect my laptop's actual BT hardware. – ProfK – 2010-10-27T12:53:45.800

An addition to what harrymc said; maybe this is trivial, but just just make sure you are not too far from the computer. I think normally bluetooth is best in 10 meters radius.

nothing is ever trivial solving a problem like this, thanks, but my phone is always right next to my laptop when I use it to connect. – ProfK – 2010-10-28T12:01:08.650
