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.
