Changing Password

Hello, this is not my field of expertise but with a little help I’m hoping you can help me.

I have a Cnpilot R200p. It had been reset and went back to default. I figured out the default password but how do I change the default password to something I want and also how do I change the network wifi name. I figured out how to log on to the setting page but on my mobile phone, am I able to do it on my mobile phone or do I have to do it on a computer?

I hope you understand, this is not my field but it’s better if I learnt than call the net guy to come out because he’s not very reliable. Oh I have satellite internet I don’t know if that makes a difference or not.
