Xfinity Xpod

I purchase 3 Xfinity xpods and is been almost a month that I have them and they are green, connected but always display no device connected. I have 2 TVs, 1 pc, 4 laptops, 2 tablets, 4 phones and 6 streaming devices connected to only one gateway and signal drop in the first level of my home. How can I connect the nearest devices to the nearest xpods??..
