My internet MAYBE?

Hiya peeps! Just a real quick question? I have had my portal for a few months now, and I love it! It’s definitely coming in handy as my HDIM port is broken and my TV can’t receive the picture until I get it repaired. The question is, what are some ways to have you portal keep connection without kicking me out I have went AFK in many games and feel like I am playing on a psp with the choppy graphics lol. I have looked it up and the net says try and use a Ethernet cable. Will maybe grab one this week. I don’t understand because I don’t have connection issues on other internet when I am out and the internet that I use while out is weaker then mine. I made sure to get internet for three gamers in the house, could be all the devices that’s connected or maybe upgraded internet? Anyone else dealing with this issue?

Thank you for your help! You rock!
