Windows 7: Internal network adapter not recognized

13 Aug 2014   #1

Win 7 Home premium 64bit
Internal network adapter not recognized

I've been dealing with this issue off and on for a while so I'm hoping somebody knows how to fix this! I have a Lenovo Ideapad Z575. I recently installed a clean copy of Win7 Home premium 64 bit and was able to update all drivers except for the wireless lan one which I downloaded from the Lenovo site. There are no warning/caution symbols in the device manager except for bluetooth.

The problem I have is twofold. First I have been experiencing intermittent connectivity with the wireless connection itself. In some cases it shows no networks available even though I have a phone, other computer, roku, etc that are all connected to the network no problem. Disabling and re-enabling the device through adapter properties will usually "fix" it so that I can connect but it's really annoying. I had disabled the power saving option and that didn't seem to help any.

The more pressing issue now is that I can't even update the driver because I get an error that says "Driver install/uninstall need your Wireless Adapter to be inserted into your PC. Please make sure your Wireless Adapter is in your PC." It's an internal wireless card so I have no idea what the issue is. The available networks icon with the yellow star in the system tray will flash that there is a network available for a few seconds but then it has been changing back to no networks found before I can even connect. The card properties show its a Ralink TEchnology 802.11n wireless card in pci slot 6.

Might just be a hardware failure from the get go, but can internal wireless cards even be replaced on a laptop? If so Thanks for any help you can offer.

Any advice would be appreciated. Thanks!

Quick update -

After searching around online it sounds like this is a common problem with this laptop/wireless card. I'm not the most knowledgable guy about this stuff, but would upgrading the wireless card fix the problem? I'd have to mod the bios too since Lenovo has the black/white list for wireless card but that might be the easiest solution?
