Missing Network Adapter Driver after reinstall Windows 7


Jan 18, 2014
Reinstalled Windows 7 because my computer was running way slower than usual. After, the device manager showed Ethernet Controller and Network Controller as missing so I cannot connect to the internet. I have a Toshiba Satellite C650D-007 model number PSC0YC-007026. I went onto the Canadian Support page under Drivers and could not find one called Ethernet controller or network controller. Am I looking for the wrong thing??

I encountered something like this before, been trying to rack my brain on how I fixed it..

Have you gotten a CD with whatever Modem you have? Also, did you check your Device Manager page (in Control Panel) to seeif the Network Adapter feature shows up, and scan for changes?

Sorry if I'm useless but I know it's always good to check your Device Manager, as well as using the CD that came with your Modem or MOBO (if you ever changed it).


He said his network controller was not showing in Device Manager.

You probably have at least one unidentified device showing in Device Manager, one of them is certainly your Ethernet controller. This is why you always locate your device drivers BEFORE you re-format your hard drive and re-install Windows.

What you're looking for on the first Toshiba link that RandomTox supplied is what Toshiba calls a "Lan Driver", assuming you've got the 32-bit version of Windows 7. If you have 64-bit Windows 7 then use his second link. In either case, download the Lan Driver to another computer and transfer it via flash drive or CD, then install it.
