Arris NVG599 Passthrough Setup for Eero Pro 6E

I have the Internet working on the Eero Pro 6E and I have passthrough setup.  Do I need to change anything?  Speedtests show 90mbps but downloads are slow for files and only reaching about 26mbps.  I can't tell for sure if the Eero is giving out the IP addresses or it the Arris is:    This is my ip address connected to the Eero.   Link-local IPv6 Address . . . . . : fe80::8d0b:bf7:c92:d78c%4
   IPv4 Address. . . . . . . . . . . : 192.168.4.24
   Subnet Mask . . . . . . . . . . . : 255.255.252.0
   Default Gateway . . . . . . . . . : fe80::6697:14ff:fe16:6db2%4
                                       192.168.4.1

but on the IP Allocation tab, it shows this:  192.168.1.64 / eero
