I bought 6 xFi Pods and after working perfectly fine for about a month, they started dropping connections and going offline very frequently. Restarting the xFi router and pods several times did not resolve the issue. xFinity customer support replaced 3 of the 6 but I still had the same issues, at which point they gave up. I ended up unplugging all 6. A complete waste of ~$250. Did anybody face similar issues?
