Answer #1
The only way I know is to login to the router trough your browser..But you need to know the username and password…

Answer #4
first, find what your local ip is
it’s probably something like this
192.168.1.xxx
or
192.168.0.xxx
or
192.168.2.xxx
then replace the last 3 numbers with another number (1-255) and ping all of them
