xfinity stream app says not in home network
My xfinity stream app does not recognize my roku stick or (on some channles) my amazon fire stick as being on my home network. Xfinity stream works when I use it on a browser on my chromebook. Before I put the archer A7 in as the router and used the M5 in router mode, there was no problem. However, even when I plugged my roku ultra in directly to the A7 with a hardline, it sill said I wasn't in my home network. Please help. I need the A7 for my son's xbox chat, so I can't go back to M5 as router.
