Do u have another ethernet cable we can try with the iptv box?

I have already tried that. Doesn't change anything. I have to go next door every time I make a change you suggest.It will boot to inner portal I am sure because it does that after I default which I have done several times. What will I do after it goes to inner, reenter portal and save?
 
And we have a winner. I works direct from modem. Maybe I need a new ethernet cable going to the box a router? Because, remember it was working fine up until July 2. That router also supplies the iks stb. She says it has been freezes a lot. Thank you, thank you thank you. Now info to fix router issue?
