CBR40 Xfinity Upload Speed Droppped
I started with Xfinity provided modem/router with new service 1000 Mbps. I used the provided modem/router for a week worked perfectly. I have two desktops wired and a iPhone. In that first week I ran SpeedTest on SpeedTest App on all devices & desktops. I was usually getting 900 Mbps down / 40 Mbps up on desktops and about 500 Mbps / 30 Mbps on iPhone.
I was trying to improve the coverage to work in the downstairs area and bought the Orbi CBR40. Instation went fine, except my Speeds on same desktop and devices have dropped. Desktops now about 725 Mbps / 6 Mbps & iPhone 500 / 5 Mbps. The download speeds are fine its the upload on all devices (wired & wireless that has dropped from 40 Mbps to 6 Mbps. Again same cables, devices, desktops, etc. I even unhooked and rehooked the same wires, devices, etc to Xfinity rental unit and the upload speed went back up to 40 Mbps.
The setup is Cable (Xfinity) into Orbi CBR40>wired directly to desktop.

Have the ISP check the signal and line quality UP to the modem.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.What FW is currently loaded on the CBR40...
Be sure your speed testing with just 1 wired PC connected and no other devices connected or streaming when your speed testing.
Be sure Armor and Circle, QoS Access Control or Traffic Meter is not enabled.
