Seems like a great suggestion - but no internet access from affected machine. That's the real problem. I can update drivers with the best of them-- unless it's the ethernet drivers so it's impossible to establish any kind of network or internet connection.
Is the motherboard info on the Dell specs? Have access a different Windows machine with working wireless. Perhaps I can usb it to the affected machine?
Instead of using the updater, use the find driver myself.
Thanks so much for your help! Worked perfectly. Selected the correct driver at Dell, downloaded then copied over to usb, transferred to completely buggered machine and presto, installer saw the problem, installed itself, restart and my friend was back in business! So glad I found you all.
