I have an Inpsiron 1545 running Vista. A couple of days ago, it stopped detecting wireless networks.
When I run the windows diagnostic to check why it can't find any networks, it says that the wireless function is turned off. It's not though -- I've tried turning the wireless on and off using f2, restarting the computer, etc, but it doesn't help.
It's not an issue with my router -- I live in an apartment, so the laptop could typically detect all my neighbors' networks. The internet connection works fine via a cable.
I'm wondering if I need to replace the wireless card, or if there are other things I should try. Thanks.
