I have TP-link TD W8151N modem n router ADSL2+ .
I am unable to open 192.168.1.1 .
But when I ping 192.168.1.1 from cmd I recieve replies .
No username or password box is promoted when I try to open the IP .
I tried reset it many times but again I am facing this problem .
After reset it opens but after sometime it again stops to open that page .
I switched it off and when after sometime I switched it on .
I was again able to open the 192.168.1.1 page but again after sometime it didn't open .
Try to clear your browser cache or you can use other web browser like mozzila firefox or others..
If still cannot login to your router, try to hard reset button using a sharp object such as the tip of the pen or the needle or paper clip, press and hold for 20 seconds, release and wait until the router reboots.
