I'm using a Dell Latitude D630 running Windows XP SP3 and recently installed a Bluetooth card and downloaded the software from Dell's website. The Bluetooth works fine in that it pairs OK with my tablet and phone, but it also tries to set up a Bluetooth PAN and a new cabled LAN connection, which says the cable is unplugged. I don't know what this is for, but in the process my laptop can no longer use my cabled LAN connection to my router, only the wireless which works fine. Under Control/Network Connections the cabled LAN connection looks OK and I haven't changed any of it's settings, so don't know what to do to be able to used it again. I did try uninstalling the new cabled LAN, but if I re-start my Laptop it re-appears! Any ideas?
