Maybe if there's some way to check the history of installed updates I can then track down which might have caused the 5100 to enter this mode of frequent disconnection. I can pinpoint the day when this started happening a few months back. But the issue can't be soley in my wireless router because every other computer, hand held device etc works perfectly and as I said, so does my USB plug-in. I noticed that the Intel adapter worked flawlessly for several hours at another location last week. It doesn't make sense that these problems wouldn't present out of the box if it wasn't a situational issue. Yeah, I too purchased a Medialink USB wifi adapter and it works flawlessly, but I'd much rather have my onboard 5100 agn perational.

There are three other laptops in the home which work just fine and never drop connection. I have not made any changes in the last 12 months to my wireless network settings in the router or on the computer. I have tried using the latest version driver from the Intel site (13.4.0.9) and that has the same problem as the version that is the latest on my laptop vendors site (13.0.0.107). Sometimes the scan will not find it and all I can do is re-boot. I try scanning for hardware changes and sometimes that will find it and I can re-enable it. Sometimes when I go into device manager the adapter isn't even listed. Now it is disconnecting as often as every minute or two. A few weeks ago it was disconnecting one or two times a day. I go into device manager and disable the adapter and re-enable it and it works fine for a bit and then disconnects again. I boot the computer and the light will be blue. On my laptop there is a light that shines blue when connected and orange when not connected. The Intel WiFi Link 5100 AGN adapter keeps dropping connection.

I'm having a problem that just started with my 2 year old laptop.
