I have a Zyxel C1000Z from CenturyLink that I had been using for wireless in my home. That device sucked, so I turned its radio off and connected a Linksys E1000 v.2 running the newest version of Tomato I could get on there. I'm not a network engineer, and am confused how to fix my problem. When I turn this setup on, I can't connect my Xbox One (running wirelessly) to my laptop that is serving as the Plex server. Everything I've read tells me it's an issue with the secure connection that Plex requires.
Can someone help me understand what/how I need to configure everything to get this to start working again?
