Windows 7: Laptop suddenly will not connect to Netgear R6300 router

Laptop suddenly will not connect to Netgear R6300 router

Hi everyone!

I've come across a problem connecting my laptop to my Netgear R6300 router. It all started out of the blue, yesterday. For some reason my laptop refuses to connect to the router. It sees the SSID, but when you try to connect it will error out stating windows can not connect to.

I tried power cycling the modem, router, laptop. No dice there.
Tried resetting the router. Nope.
Tried using a restore point to go back to before I updated recent windows updates. Didnt work.
Tried uninstalling the wireless card through the device manager, rebooting, reinstalling. Didn't work.

I'm currently on my desktop, which is wired. No issues there. Also my tablet and cellphones connect to the router without any problems. It's only the laptop. This lead me to believe possibly a faulty wireless card inside (which would suck). So I setup my cellphone as a hotspot. Sure enough, the laptop connected just fine!

Something is getting in the way of the laptop and router not playing nice with each other.

Running Win 7 64bit
Norton Antivirus

Any other ideas?

It sounds like you covered most of the obvious problems here.

Did you try deleting the old wireless connection profile then create a new one with the current SSID, password etc. You can do this through the Network and Sharing Center, then left side go to "Manage Wireless Connections" Sometimes the profiles get corrupted and need to be redone.

If you can post a screen shot of the ipconfig/all it would also be helpful.

Yes, I did try deleting the profile.

Here's my ipconfig.

Yep, no connection showing up here at all. DHCP is also turned off for the wired connection so I assume you are using a static IP for that.

Try running the file below which will reset the network stack, renew the IP and flush the DNS among other things, it will also reboot your system after it runs. Let me know if this changes anything.

If this machine connects to the cell phones hotspot as you say then most likely there isn't anything wrong with the network adaptor. You did mention resetting the router but it sometimes requires a 30-30-30 reset in order to get routers working again. After this it's required that you set up the router again using the correct SSID, security should be WPA2 personal and encryption which should be AES.

Yes I realize that you have other clients connected wirelessly but this logic does not always pan out like you would expect.

I tried the 30 30 30 reset. Still will not connect wirelessly.

In this case I would suspect that Norton is somehow involved so you might want to try disabling Norton for the time being.

I don't know. I may try just uninstalling Norton and see what happens. If that doesnt work I may just go for a full reformat/install (painful).

When you remove Norton you must use the special uninstall tool for it or else any problems Norton may have caused won't be fixed.

You might also try running the system file check by running the following command in an elevated command prompt.

Code:
sfc /scannow
