Internet Speed is Lower Than it Should be
Hey all I have tried various searches to find an answer for this, called Comcast, Asus, Netgear, had techs out and so far, nothing, but let me tell you what is going on.
Last week I had 900mbps download from Comcast and they upped it to 1000mbps, but I was still getting 800mbps-940mbps on my desktop when I ran a speedtest.
Late last week I upgraded to Comcast's 1200mbps package and because my old modem maxed out at 950mbps or around there, I updated it to the Netgear Nighthawk CM2000 which has the ability to do up to 2.5.
My desktop motherboard is the ASUS ROG STRIX Z490-A which has a built in 2.5 NIC.
My router is the Netgear Nighthawk Raxe290. I have a cat8 cable going from the modem 2.5 port to the 2.5 internet port on the router. I then have another cat8 cable in port 1 of the router going to my desktop.
I changed the NIC on the desktop in device settings to use full duplex 2.5.
When Comcast tested the speed in the house and at the modem it was coming in at 1350-1400mbps. When I do a speedtest on the router I am also getting 1350-1400mbps; however, when I do a speedtest on my desktop I am only getting 700-900mbps. The same is true on my Alienware m2 laptop that I believe also has a 2.5 nic.
I am really not sure why I am not getting that full 1200mbps+ speed I should be getting from Comcast. I tried calling Netgear today, but they transferred me around and after being on hold for over an hour two separate times I just hung up. If anyone has any experience fixing this or advice, I would be extremely appreciative!
Thanks!

For testing, have you connected your 2.5 Gbps port on your desktop directly to the 2.5 Gbps port on your modem? You would have to power down both your modem and computer, then power up the modem and allow it to boot followed by the desktop to establish the connection. If your throughput testing matches your performance plan, Comcast has done their part.
Looking at the specifications on your router, it only shows one 2.5 Gbps port on the back. It can be configured as a 2.5 Gbps WAN connection. The other yellow port (#1) is a 1 Gbps connection as are your other LAN ports. Normally a 1 Gbps port runs at about 93-95% efficiency, thus you are seeing the nominal 940 Mbps throughput.
It looks like I won't get the speed I want with this router wired, but what if I bought a wireless card for it, since the wireless for 5ghz and 6ghz seem to go beyond the 1mbps?

Maybe. I do not own any Wi-FI 6 or 6E hardware. What specifications seem on paper are seldom matched in the real world.
Comcast just increased the specified download throughput of my plan from 800 to 1000 Mbps. With over provisioning I should see around 1.2 Gbps. I do not have any downstream hardware to test once I get past my modem. I cannot imagine doing anything to saturate that connection and plan to downgrade it in exchange for a higher upload throughput.
