I find it ironic that modems and routers are still 'stuck' with 1gBASE-T ports. Currently, the only way to attain multi-gig (in this case, only 2 gig) connectivity from a standard modem or router is the use of link aggregration via Cat cables. Sad.It is very important to note that USB 4.0, HDMI 2.1 and DisplayPort 2.0 all have about the same throughput (approximately 40 gigabit). Ethernet is somewhat stuck at 10gBASE-T, 10 gigabit (because it is typically used over longer distances).
Having all this duplicate technology is a complete waste of time and just encourages dotard, foot-dragging types to hang on to obsolete technology.
