Windows 7: Wireless network adapter suddenly not working

Wireless network adapter suddenly not working

I have had my HP Pavilion dm4 for a year and a half now, and when my school gave me a copy of Windows 7 Enterprise (it came with Win7 Home) I installed it and all the necessary drivers, and everything's been running smoothly - til now.

Tonight all of a sudden my Internet connection showed that it was connected but had "limited connectivity" - aka no Internet. So I restarted my router - no luck. Then I restarted my computer, and my F12 wireless button showed orange - meaning that wireless capability was turned off entirely. It wouldn't turn back on even if I pushed the button, so I went into Control Panel and did some diagnostic thing and it forced the wireless capability back on and it worked again. For about an hour. Then the button went orange again and the diagnostic couldn't turn it back on.

So, I went into wireless connections and disabled and reenabled the actual connection rather than the adapter, and it worked again - for about another hour. When it went off again, the disabling/reenabling didn't help.

I don't think it should be a driver problem seeing as I can make it turn back on for certain periods of time and it's worked fine until now. Does anyone know what to do?

Do you have iTunes or AVG installed on this system?

If you can post a screen shot of the ipconfig/all from this machine it would be helpful.

I'm not sure what AVG is, so I don't think I have it, haha. I do have iTunes installed but it's never caused problems before and I don't usually run it unless I'm syncing my iPod. It wasn't running at the time of the issue.

I would be happy to post a screenshot of the ipconfig /all but when I type that into Run it opens and then immediately closes again, not sure how to keep it open long enough for a screenshot.

You would type ipconfig/all into an elevated command prompt in order to get the network stats. If you can use the snipping tool to post a screen shot it would be helpful.

IP Address - Locate and Find for Your Computer

The iTunes can turn into a problem at anytime because of a service it installs called Bonjour which causes networking problems on a regular basis.

AVG is an anti virus software that has a wireless filter that also causes problems but if you don't have it install your ok.

You will need to go into Windows services > run then type services.msc, locate the Bonjour service and Stop the service then reboot your machine. This is just to eliminate that as a possible problem. Your iTunes will still work.
