I have a fairly new Asus RT-AC68U which I currently use, and an older D-Link DIR-825 which isn't being used.  Turns out I need to use the D-Link.

 

I unplug the Asus and plug in the D-Link into my PC.  I got to 192.168.1.1, and see the following:

 

Settings have been updated. Web page will now refresh.
Changes have been made to the IP address or port number. You will now be disconnected from RT-AC68U.
To access the settings of RT-AC68U, reconnect to the wireless network and use the updated IP address and port number.

 

What?  I am not logged into the Asus router.  Maybe it is cached in the browser.  Do a hard reset on Chrome, but still there.  Maybe I have some special built in wireless in my desktop.  Unplug the router, but still there.  What can possible cause this?

 

Then I do some searching and find D-Link typically uses 192.168.0.1.  Try it again, but just get the blank "There is no Internet connection".  When I try running Windows Network Diagnostics, it says an Ethernet is not connected, but I clearly see that there is.

 

Guess my issues can be one of the following:

  • The Asus router still has some strange control over my PC even though it is unplugged.
  • I shouldn't be using 192.168.0.1 but something else.
  • D-Link is dead.
  • Maybe I am using a CAT6 cable, but the DL-825 uses CAT5.

 

Any thoughts?

Have you tried resetting the D-Link router to it's factory defaults?

 

You could also try clearing some of your network configs on the PC.

 

From a command prompt try the following:

 

netsh interface ip delete arpcache

 

ipconfig /flushdns

Thanks Rang0,

 

Yes, tried resetting D-Link router to factory settings.  If memory was correct, hold the button down for say 6 seconds, and it should reset, right?

 

Also, tried your flushing cache and dns commands, and Asus was still alive and kicking...  Crazy!

Is your PC set to use DHCP?

If yes, use the command:

 

ipconfig /renew

Yes it was.

 

First was plugged into the D-Link router, ran the command, and it shows as being disconnected.

 

Still want to figure out why the Asus router keeps on coming back from the dead.  Went back to the Asus, ran the command again, plugged in the old router, and it still shows the Asus page.  Crazy!

 

Guess Windows must just have some persistent caching which doesn't go away if there isn't a connection.   Maybe just time to get a new old backup router!

It is not clear to me...but have you cleared the browser cache after you switch from the Asus to the D-Link router?
