Packet loss between my PC and modem
So I'm trying to figure out why I'm experiencing some pretty heavy packet loss within the past few days that seems to be affecting only my desktop PC. I have a Netgear Nighthawk AC3200 Wi-Fi Router with DOCSIS 3.1 Cable Modem, that is roughly 10 feet away from my desktop PC. My PC has an ASUS ROG Strix Z490-E motherboard with an Intel Wi-Fi 6 AX201 adapter. Speedtest results average around 650Mbps down/25Mbps up. I'm not really sure what to do here. I have done a factory reset on my modem-router, updated my wifi driver, reset network settings on my PC.. can't think of anything else.
Here is a trace to a videogame server (Valve Matchmaking Server (Virginia srcds1155-iad2 #4) 162.254.192.147);

A lot of questions about routers are generic. In this case you are asking about connection issues with a cable modem.
You might get more help, and find earlier questions and answers specific to your device, in the appropriate section for your hardware. That's probably here:
Cable Modems & Routers
I will ask the Netgear moderator to move your message.
In the meantime you could visit the support pages:
Support | NETGEAR
Feed in your model number and check the documentation for your hardware. Look at the label on the device for the model number.
You may have done this already. I can't tell from your message.
I mention it because Netgear stopped supplying printed manuals and CD versions some years ago and people sometimes miss the downloads.

There have been driver issues with Intel's Wi-Fi 6 devices.
- sh1roAspirantI haven’t had any issues before with the Intel Wi-Fi, so I’m not sure what to do here. I have tried multiple driver versions, including one that was released a few days ago, version 22.100.0.3.

Do you see same loss with a ethernet connected PC to the back of the modem with ALL other devices disconnected and WiFi turned OFF on the modem to test?
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute then back ON.

- sh1roAspirantI don’t have a long enough ethernet cable to reach my PC, so I ordered one and it will be here tomorrow. In the meantime, I went out and checked the cable from the modem to the outside cable. There are no visible issues that I could see, no splitters, etc. Xfinity was out before due to a complaint of low connection speed and they recommended that we purchase this modem router. Everything else was fine according to them.

Update: I have peformed a test using an ethernet connection and the problem still exists. Reinstalled Windows as well.

What trace do you see with just 1 wired PC connected to the modem and with ALL other devices turned OFF and disconnected from the modem. Turn OFF the wifi radios on the modem as well. Use the pingplotter.com site to test. Do not get with a game server.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute then back ON.

https://www.duckware.com/tech/solving-intermittent-cable-modem-issues.htmlOut of curiosity, I plugged a brand new M1 Mac Mini into the modem/router using the ethernet cable and gave packetlosstest.com a shot. According to that site, there are zero dropped packets, but 44% were late (1321/2999). Average latency of 53, 6ms jitter. I can see that some packets had response times upwards of 177ms, while the best ones were 46ms. I turned off wifi radios prior to testing, ensuring all devices were disconnected. I also noticed that there is no known ISP service box from what I could see, as the coax cable that enters my home runs up the side of the house and is then suspended in the air, connecting to a utility pole. I tried another coax coupler in case that was the problem, but no change. I checked again for any splitters and did not find any, nor did I find any cable line issues after performing a thorough physical inspection. Confirmed that the coax cable up to the modem is a high quality RG6 cable, and did another one-minute power cycle on the modem. I think I am running out of ideas here.
