So I have windows 7 on a dell with wireless internet that works fine....till a few days ago. For no reason, i could no longer  connect to my computer. It recognizes that the connections are available, but it can't do it wireless. The only way I have internet now is though a cable cord, which makes me realize that it's something wrong with my computer. I tried a system restore to before the problem SHOWED up, but that did nothing. I also tried looking at the boot menu at startup and flipped on and off the wireless internet connectivity abilities, which did fix my problem for a day, but not anymore. I also tried troubleshooting it through windows, but all they said is that i just can't connect wireless. I'm concerned that it may be malware or something else, and i've been scanning with everything I have, but I'd love some suggestions about what's causing this and how to fix it.
Thanks guys!What do you mean you've looked at the boot menu? Is this a laptop or DESKTOP? Have you tried reinstalling wireless card drivers? at the startup of the computer, you can run memory diagnostic and choose which drivers to run, and so on. And honestly, I don't even know where to look to find the software to reinstall it. The strangest thing is that now I found out that my computer is only having problems with my internet at HOME. I went to a friend's place and for some wierd reason it worked just fine. But i've already tried resetting my router and suchDo you have anything else to connect wirelessly? If you do, does it connect fine? Can you POST your router specs?
