Cannot log in to router from one Win7 comp but can from other; Inet OK

[WinUser7777]

Hello, experts:

I have a Netgear Nighthawk R7000 router and two laptops running Windows 7 Home Premium. I can't access the router's admin interface from one of the laptops, BUT I can do so without a problem from the other laptop. The IP address I type in is http://192.168.1.1., and I get the generic error page, "This page can't be displayed", in IE. I have also tried Chrome and Firefox. I can successfully ping the router from the Command Prompt. The IP configuration of the laptop (ipconfig from DOS prompt) correctly shows the default gateway at 192.168.1.1 and the laptop's IP at 192.168.1.2. The subnet mask correctly shows as 255.255.255.0, as do all the other IP parameters.

The Internet is working fine on all devices, including the problem laptop.

The laptop's IPv4 settings are set to autoconfig; DHCP enabled.

I have also tried a wired connection between the laptop and the router with a LAN cable with no success. The router fails to detect the laptop's wired connection: the corresponding LAN port light on the router lights up for about a minute, then dies.
I have also tried booting the laptop from a Ubuntu Linux disk, and the connection to the router's interface WAS successful and immediate, both wireless and wired.



Things I have already tried:

• Many, many hours seaching the various forums
• Restarting the laptop, router and modem in all possible successions many times
• Disabling the Windows firewall and Kaspersky antivirus
• Pinging the router at 192.168.1.1 -- the ping is OK, no packets lost
• Assigning the laptop a static IP (e.g., 192.168.1.6), then reverting back to autoconfig because of no success
• Resetting the router to factory defaults (again, can access the router from one laptop but not the other)
• Flushing the laptop's DNS cache from the DOS prompt using the netsh commands
• Uninstalling and reinstalling the wireless adapter driver and the wired LAN driver

Any help will be greatly appreciated. To me, the problem seems to be in this particular laptop's Windows network configuration, because:

(1) I can access the router's interface from the other laptop and even my phones
(2) I can access the router's interface from the problem laptop when running Linux/Ubuntu.

Attached are my ipconfig output and my IPv4 config snapshot.

Thank you all!

Welcome to the forum. Do you know is the router page uses JavaScript I have known this to happen if it does have you tried safe mode

Yes, the router page uses JavaScript. Yes, I have just tried Safe Mode w/networking and I still get "This page can't be displayed".

to make sure your hosts files is not hosing you, google "Blocking Unwanted Connections with a Hosts File"

also try internet explorer

Googled, downloaded and updated the hosts file. Using Internet Explorer. Still no connection to the router interface.

It's normally either antivirus or JavaScript corrupt disabling antivirus doesn't always work you may need to stop services does it load other JavaScript sites ok
