CM1200 Modem to RBR20 Speed Issue

I've been having speed issues.  Xfinity tech was here earlier and tested 1255 directly off the coax.  He could not pull a reading from the modem directly. I have the Orbi connected directly and the speed I get via the app (iPhone) is ~495/42.  I think that reading is not via wireless, but directly from within the Orbi to the modem.  If so, then clearly I am losing a lot of speed.

 

Can anyone direct me on the steps I need to take to close that gap?  I just updated the Orbi firmware.

 

Thank you,

    With a wired ethernet PC directly connected to the CM modem with out the RBR online, what is your speed seen with Ooklas installable speed test app? Then try with a wired PC connected to the RBR in line with the CM modem. 

     

    WiFi speeds will max out at around 400-500Mpbs on 5Ghz AC due to the 2x2 antenna design on phones and pads. 4x4 antenna design can't see over 500Mpbs.
