I found this Dell Quickset driver download and it let me enable my wifi. Thanks for your advice if it happens again I'll do as you said.
I bought a new router and configured it wirelessly thru my wifi. Everything was working fine. Got back on my laptop and nothing. I have checked bios, enabled thru device manager and reviewed the mobility but it is greyed out and won't let me turn it on. I have updated the drivers by connecting directly and still no wifi. I appreciate any help you and am willing to do everything possible to go back wireless. I also did a system restore before to no avail before I updated the driver. Thanks for any possible help.
