next gen speed configuration - CM3000 and RAX70

Hi,

Next Gen Speed Tier is available in my area and I got a modem off this list that works for that.

I had an xfinity tech visit and he can pull 1800MB download and ~400MB upload directly off of the coax cable.

However, I max out at 900 down / 300 up. I have the most expensive xfinity plan (e.g. theoretically 2gig down).

When I log into my modem (Nighthawk CM3000) this is what I see:

When I log into router (Nighthawk Tri-Ban AX8 RAX70) this is what I see:

I tried changing the settings in the modem to enable port aggregation but the only thing that after the modem rebooted is kick me off the xfinity system.

I then had to chat with xfinity support to get them to reconnect me - but I couldn't get them to do that with the next gen speeds allowed.

I do not want to rent an xfinity system. I have too many IoT devices and need to be able to manage my own network.

Does anyone know how to set this up so that I can achieve the speeds that should be possible here?

Thank you

update that I think I configured this properly now. my problem was that I didn't connect from port 1+2 on modem to 3+4 on router and then I had to do the setup in router + modem before connecting the second cable.... so the sequence was:

[1] connect router to modem via the yellow jacks on both

[2] on modem activate aggregation (and wait for it to reboot) (advanced --> ethernet port agregation --> enable)

[3] on router basic --> internet --> ipv4 tab - WAN preference - multi -gig (1+1).

[4] connect an ethernet cable from port 3 on router to port 1 on modem.

[5] transfer the ethernet cable from the yellow jack on modem to port 2

if you did correctly a blue "WAN aggregation is active will appear. "
