I have a new just out of the box Dell Studio PC with Windows 7 64 bit OS.
Unable to install a Netgear router model DGN2000 using the enclosed installation cd or the netgear installation web site www.routerlogin.com. All I get is error code 651 when the router tries to connect to my internet server (att.net) Have tried installing router manually and using the automatic settings. No luck with either. Netgear and ATT are no help. Got cut off while on the phone with Dell techs today. Anybody have a solution?
Wow made me work for this one. Apparently this has been an issue and like normal micosoft is aware of it and is currently working on a solution in the meantime I went to many, many forums and they all tried a lot of stuff and none of it seemed to work...except this one from http://www.ehow.com/how_4815578_install-netgear-wireless-router-cd.html he says to install it without using the cd to work around this issue, out of the billions and billions of forum threads I read this seems to be the only one that worked all the others said at the bottom that they tried what was suggested and is trying to contact att support...apparently with very little success which really isn't surprizing as they do acknowledge the issue and are currently working on a solution..sounds familar, eh? Hope this works for your
Turn off your computer and modem.
Locate the Ethernet cord that runs from your modem to your computer. Unplug the end from your computer.
Take the unplugged end and plug it into the Ethernet port on the back of the Netgear router.
Plug the Ethernet cable that came with the router into the LAN 1 port on the back of the router. Plug the other end into the Ethernet port on the back of your PC, the same port you unplugged the Ethernet cable from in Step 2.
Plug in the modem and turn the power on. Wait 2 minutes.
Plug in the router. Wait another 2 minutes.
Turn on your computer and check the lights on the front of the router. All four lights should be lit. If the third light is not lit, check the Ethernet connection from the router to the modem, making sure it is secure and the modem is turned on. If the fourth is not lit, check the Ethernet connection from the router to the PC, making sure the connection is secure and the computer is turned on.
Open your Internet browser and type "www.routerlogin.net" into the address bar.
A login window will open and ask for a username and password. Enter "admin" for username and "password" for the password. This is the default setting for Netgear. If it does not work, check the paperwork that came with the router.
Once you connect to the router, a setup wizard will open. This setup wizard will walk you through the final process of configuring your router.
Firstly, there are several reasons for the cause of error 651 and at the same time, there are different solutions for each of them.
One of the ways to fix this error is IPv6 connection
Open Network and Sharing Centre and select your connection and click properties
Uncheck Internet Protocol Version 6 (TCP/IPv6) and click Okay
Restart your device and check if it fixed the issue. If not, check this guide to know other possible solutions
