I don't have warranty on my modem. The model number that I have is SBG6700-AC. I've had it for a few years. In the past, I've always used this IP address http://192.168.0.1 and was able to login into the router using admin and password to go in and change the SSID along with the password. For some reason whenever I attempt to log in with that IP address on my laptop or smartphone, I get the message:
This site can’t be reached192.168.0.1 took too long to respond.
Try:
Checking the connection
Checking the proxy and the firewall
Running Windows Network Diagnostics
ERR_CONNECTION_TIMED_O
I really want to change the SSID along with the password. Is there another way I can change the SSID and password?
