CAX30 - wireless speed
I just got a new laptop with an Intel Wi-Fi 6E AX211 160MHz wireless card. I cannot get beyond 1201 Mbps, which is the same speed my previous laptop hit. Is there something I could have set...

This is expected.
The CAX30 has supports 3x3 with 80 mhz channels, which gives the max link speed of ~1800 mbps. Note the 3x3 is the number of antennas (three transmit, three receive).
The AX211 is 2x2 (two transmit antennas, two receive). If the CAX30 supported 160 mhz channels, you'd get a max link speed of 2400 mbps. But since the CAX30 is limited to 80 mhz channels, the max link speed is half that (which is what you are seeing).

Thanks, Steven! That makes sense. My ISP is putting in fiber sometime this year, though they are not very specific as to a date! I don't imagine it would be a good idea to buy a new modem capable of faster speeds.

The modem itself should be able to handle 2 gbps+ service from your ISP. That is of course total throughput (shared across multiple clients).
As far as the laptop goes, so far we are talking about wifi link speeds. Actual internet throughput is quite a bit less - generally ~500 mbps. Personally I find that to be fast enough for a single client.
Each LAN port can support 1 gpbs (full duplex). So if it is practical to connect the laptop with ethernet, you would get higher speeds (assuming the ISP delivers 1 gbps or faster service).
The next step up would be DOCSIS 4.0, which isn't available yet.
