Hi Sccrmnstr, xFi Pods speeds apply just as WiFi speed applies when you aren't connected directly to your modem: You will see faster speeds when connected directly to your modem via ethernet cable. All other WiFi connections via WiFi or router (in this case, the pods) will see varying speeds.
However the drop you mentioned is alarming so I am going to send this over to the team for deeper investigation.
I can take a deeper look into the signals you're getting, in order to access your account, can you please verify your first and last name, full street address, and the phone number or account number associated with your services in a private message?
