XFi Pods

I have had my Xfi Pds for several weeks now, they say they are connected and are all named, but not one device in my home is actually connected to any of the pods and all my dead spots are still dead. Any ideas? As much as they cost, i expect them to do something, but have yet to see a customer that they work for. Help, i need the wifi coverage to work farther because i have several kids doing online school from different areas of the house.
