Ours worked great until the last week. Speeds throught the pods dropped from an average 50mbps to below 2 mbps. Only thing I can guess that that the latest modem update hosed them up.
When I unplug the pods, even with a weaker wifi signal, I can get over 200 mbps through the modem a the same location so the xfi pod is definately the problem.
Xfinity has no clue why this is happening and just gave me $20 credit which bites because I paid over $120 for the three pods
