If you suddenly can’t connect to your modem-router in the Windows operating system and receive an Error 651 notification then don’t start with the complicated explanations and suggested fixes that are littered across the Internet. Here is the simple fix that worked for my situation.
The first thing you should do is reset the router. That’s simple: poke a pin into the reset hole on the router and hold for ten seconds until the lights change. This puts the router back into factory settings and you can use your CD to set the home network back up in a few minutes.
Then, if you still receive the 651 Error notification in Windows you just need to reinstall the drivers.
To understand device drivers consider that all computer operating systems are different. It would be difficult to write permanent code for a modem/router, for example, that worked perfectly on all operating hardware all of the time. So little programs called drivers are written to match hardware with the operating system. It’s like a piece of a jigsaw or a Lego in code that operates as a translator between the device and the operating system.
The next step is to locate the device in the Device Manager within Windows. Click the device in the Device Manager and select the tab marked Drivers. Uninstall the driver.
The next step is to get some Cat 5 cable and connect your computer directly to the modem/router using connection number 1 on the router. Your computer should automatically locate the appropriate driver for that hardware via the working Internet connection and the 651 Error should be solved.
It’s fine to try all those complicated solutions recommended in forums by people trying to be overly smart among peers. However, none of these complicated solutions worked when I tried them. The simplest answer was to re install those drivers. Hope it works for you, too.
