“Only one ethernet port works on this modem I cant connect multiple devices. Is it the modem or my internet service provider? I have Xfinity”

• Depending on your situation, this is most likely as designed. The multiple ports on the back of the router do not function as ports on a router. The ports are for either routers that support Link Aggregation, or if you have multiple IP addresses from Xfinity (generally only if you have a business account, and pay for it). Here is an article from Motorola about the multiple ports: https://motorolamentor.zendesk.com/hc/en-us/articles/115010589128

• I use this modem on my computer for internet instead of renting the Comcast/infinity modem. I also have a netgear hub for other devices with my computer

• Correct. There is one ethernet port on the modem. To connect more devices, I connected a router to the modem (which also gives me wireless).
