WELL AFTER ALL OF THESE TASKS and NEW SWITCH ASSEMBLY   IT DID NOT WORK!!!!   that is until I discovered that the FIX for Bluetooth not appearing in device manager and not working is a DELL utility found here [URL]#Issue2   this worked for me when EVERYTHING ELSE INCLUDING NEW SWITCHES ETC DID NOT.   Ignore the operating system it is for it worked on my vista and on my friends windows 7. It restored my bluetooth and was also the cause of my wireless problems IF ONLY I HAD DISCOVERED THIS WEEKS AGO   Elly  
Hi Can anyone help me please  i have XPS M1530 windows vista and recently started to get this problem with wireless internet connection. I have been thoruogh all the testing with ISP even had a new router and can connect with LAN no problem.   I have intel (R) Wireless wifi link 4965AN and Marvell yukon 88E8040 PCI-E fast ethernet controller.   Dell diagnostics says the wireless device is disabled but it is not disabled in device manager? Intel diagnostics says the hardware radio is off but the radio button is switched to on on my laptop.   I have reinstalled the drivers and not being very technical cannot think what to do next.   Any help would be most appreciated than you so much.   Elly
Wifi switched off will come on intermittently then switch off again?
