Unable to access router's configuration page (192.168.1.1)

The router is a TP-LINK TD-W8951ND.

I tried to access the configuration page through Wi-Fi and through wired connection both didn't work. I tried restarting (the problem has been persisting for a while actually) i also tried using a different browser and different computers but all without luck.

The default gateway is 192.168.1.1 and the ping works well. I can't seem to figure out. Any help would be appreciated.

I had similar problem and accidentally found the solution for it. This is how I solved my problem to view router home page.

First in windows go to control panel> Network and internet

from the Network and Sharing Centre go to View network computers and devices inside that window you can see your router device. Using third mouse key open menu in your router device icon and select first option View device webpage. It should open 192.168.1.1:xxxxxx page with your router home page. I am guessing that 192.168.1.1 requires certain port to open the router home page.

It’s probably because the router firewall is enabled and prevents the other devices to connect to it. In this case you have to reset the router (by pushing the reset button with a pin or power off then power on after about 15 seconds). When the router comes up, you can access the admin page only for about one minute. In this period, you have to login the admin page, open the firewall tab, check the disabled radio button and save the new setting. Perhaps you have to do this procedure more than one time, because the connection may be lost sooner than you can change the firewall setting. During connecting to the admin page, you have to refresh the http://192.168.1.1 address page (by pressing F5) again and again to be loaded. After you have changed the firewall setting, the router admin page will be accessible in a normal way.
