I have a Alienware m17x with said card, last week my network card started acting up. when I reboot my computer it tells me there are no networks available (and there are PLENTY including mine) i run diagnostics says everything is fine.
If i uninstall my Broadcom 802.11n Network Adapter and then reinstall it TA DA! it sees every network fine but then i have to click on mine and re enter the network key. everything is then fine, untill i reboot my laptop. Then it is the exact same thing again, nothing i can do seems to "fix" whatever is wrong so everytime i have uninstall and reinstall the network card and retype the passkey.
This happened to me a year back and I totally forget what it was that I did that "fixed" it.
Can you run an ipconfig /all log and post it back here?
What is a Dell Service Tag and how do I locate it?
