changed router ip. now cant access routers web interface

reset the router to factory default, so you can access it again, now you want to use 192.168.100.46 as static WAN IP and not local IP. choose a local IP address from a fifferent range (e.g. 192.168.101.1)

"I had the same problem today. Changed the ip from 192.168.1.1. to 8.8.8.8 and then had difficulty in logging back to the router and also accessing the internet. (a) I right clicked on the wireless icon in the taskbar, (b) went to open network and internet settings, © clicked on Change Adapter Options (d) clicked on internet protocol version 4 (TCP/IPv4) (e) clicked on properties (f) use the following IP address (g) entered 192.168.1.1 (h) clicked on subnet mask and it got entered automatically (I) clicked on 'use the following dns servers' (j) entered 8.8.8.8 and 8.8.4.4. Finally, I clicked on validate settings upon exit. That's it. It found an error which windows troubleshoot wanted to know if it could fix it. I said yes.

After that I logged into the router using the new ip 8.8.8.8/login.html
Hope this helps. Regards NAZIM"
