Step 2

Now, unplug all the cords and cables which are connected to the router and computer as well. Wait for a few seconds and then replug all the cables.

Step 3

Finally, connect the plug to the power source and then turn it on again.

Finally, after completing these steps, check whether the error code still persists or not.

Create a New Dial-up Connection:

Another process is to create a new dial-up connection on your device. This is also a very helpful way to check whether the modem is set properly to the bridge mode or not.

If your device has already been a dial-up connection, you can try to create a copy to resolve the issue. Do as follows:

Step 1

At last, try to connect the network again to verify whether you are getting the Netgear router error 651 or not.

Fix 3: Reset TCP/IP on your Windows
