This is where I'd start.
Is a new cable modem helpful?

DOCSIS 3.0 4x4 should be able to get you at least 90mbps easily instead of 22mbps. I had similar problem with my old router in the middle and it turns out the old one can only handle 40mbps before packets are dropped. It would work fine for non video conference wifi or ethernet if I throttle it down to 40mbps down and 5mbps up. New router (even a cheap one for this era) should easily handle 100mbps as long as it has a gigabit ethernet port on the WAN side.
Have you log into your modem and see what is the dB on your 4 channels down?

Can't log into my modem, it's 192.168.100.1 and the rest of my network is 192.168.1.x.
Direct hookup isn't working for some reason... have what I think is a pretty plain jane DHCP setup that I would think should translate to WAN easily.
Cable is mostly 2002 era Cat 5. Do get gigabit speeds between my (in-basement) NAS and good computer when using a gigabit switch. Have a huge roll of 5e and crimpy connectors though.

You can 'hard code' your IP address to 192.168.100.X to access it. It won't do much good as Spectrum locked us out of them (at least with many modems).
Clone the router's MAC address into the PC. Or power down the modem for 30 minutes so the cable company will forget the old MAC and let you use a new one.
You'll have to add a 192.168.100.x IP (x not 0, 1, or 255) to the Ethernet port to log into the modem when connected directly. When using a router the router considers every request for an IP outside 192.168.1.X to be the Internet and sends it to the modem by default.
Cat5 is usually fine for gigabit if the length is not too long.

Renew your IP after you plug your pc into the modem.
Try a Cat 5e cable

It's only got 100Mbit interfaces, CAT5 is more than sufficient for 100Base-TX FD.
Most big-name (like Commscope, Berk-Tek, etc) cat5 works just fine at gigabit speeds, too.

I haven't seen CAT5 for sale in ages, it's all CAT5e or CAT6. I only buy CAT6 because it would be ridiculous not to at this point, but for short runs, regular CAT5, as @mk378 noted, can do gigabit speeds. It simply lacks the twists per foot to do it over significant distance.
I have an Arris TM822G 8x4 telephony cable modem. It provides a POTS interface for a landline. I bought it used for around $35 shipped last year. It's on Xfinity/Comcast and I get every bit of the 200mpbs I'm paying for, and then some. I'm also using a Mikrotik RB750Gr3 for my router. I have a separate access point.
There is still a lot of CAT5 installed in buildings. It will actually work up to the rated distance of 100 meters for gigabit.
The reason that the CAT5e spec was needed is because some cable manufacturers (not reputable ones--likely the same ones making the CCA/copper clad aluminum junk today) were making cable that barely met the cat5 specs and would not work reliably at gigabit speeds.
I still have a couple rolls of Commscope CAT5 in the basement, I bought them in the early 2000s and wired my old house with it at that time, and later used those runs for gigabit. Worked fine.

Yes, I'm dealing with some of it in an older medical building right now. There's a ~300ft run of CAT5 that goes under the parking lot that definitely won't do gig-E, no idea who the vendor was, but that's the issue, you really don't know if they were overly generous with the twists per foot or barely met the standard because CAT5 never needed to be qualified to carry Gig-E. Even with CAT5e I have seen wild variability. CAT6 seems to be more consistent. Belden does an excellent job of very tight twists, I've been very happy with their medical-grade cabling.
So yes, some CAT5 will do Gig-E, some won't, If you are nursing along some aging infrastructure before doing a refresh, sure, see if it works, but my point earlier was simply that I haven't seen CAT5 for sale in ages so for somebody buying cable now, they likely aren't going to have that as an option anyways, it'll be CAT5e or CAT6.
Unless that's a flooded cable designed for undergound use, it's probably waterlogged and wouldn't work for gigabit even if was cat6...

It's in a conduit, it's outdoor rated cable from what I can gather and it never actually goes outdoors. It goes from a wiring closet in the main building into the conduit and that conduit comes out in the basement of another building across the lot. There's 4 runs in the conduit, doesn't appear to be any obvious signs of moisture in it, but it does look like it was relatively cheap.
Electricians have a saying:
There are only two kinds of underground conduits. Those that have water in them and those that will have water in them.
In my experience it is true, and doesn't just apply to underground conduit.

I'd generally use fibre for that type of run, but I've inherited this.
You'll likely find this amusing:
The service to the remote building was originally 6Mbit ADSL. In a consolidation effort I removed numerous extraneous services and replaced with 500Mbit dedicated fibre. I carved off a separate VLAN for that building and immediately discovered it wouldn't do 100Mbit out there and packet loss was pretty high. Best I could manage was high 40's. I rate-limited the port to 25Mbit which seemed to be a functional workaround, not a big deal, as it was only a student using the service as a tenant in the upper floor of the building, but it certainly highlights some of the exciting things you can find with legacy wiring.
I just got a new modem and Cat 5 cables came with it.
Found the cable to my office and good computer was wired up as a crossover, 36145278. LOL.
Still did gigabit before, and gigabit now. 52-ish MB/sec to the NAS and its 7200 RPM HDs.
This could explain why the direct connection to the modem was no good, though. My router must have been auto-compensating.
But, now, the kids are online with school, so further experiments must wait.

That's wild, mine came with CAT5e. My wholesalers don't even stock CAT5.
