Err...well, I'm using the ethernet now. My wifi router is still on, while the yellow cable is attached from my broadband to the mac.
When I try to access the 192.168.1.1, it says I cannot establish a connection to it.
Can you connect directly with the ethernet cable to the router?
Well, I managed to connect into the wifi, but I'm not sure it's ours.
Question: Does the wifi automatically assign a password to itself?
Cause I used this 192.168.1.1 link, but it redirected me into a wifi that has it's own password.
That would be the router password. If you didn't change it, it should be whatever the default is (probably "admin" for the user name and "admin" for the password.)
