I installed 3 xFi pods about a year ago. Since then, connectivity has been good and speeds have been blazing. Until recently. Some devices are still getting blazing speeds (> 400 MB/sec) but intermittently in some parts of the house, especially near xFi pods, speed has been inconsistent. Sometimes excellent, sometimes very slow (2 MB/sec) or not at all. I replaced the modem/router and did other troubleshooting and finally decided it must be the xFi pods. I unplugged all the pods and immediately speeds on all my devices increased. Couldn't find good info on website on how to troubleshoot pods. Should I try to re-install? or take them back to the store? or ??
