Packet Loss only on One PC

[FThay]

I've been having some issues over the past week at least (since Oct 9) where my computer experiences regular packet loss. This causes videos to buffer, but more noticeably, lag and rubber banding when online gaming - which makes it extremely frustrating to play at this point. This wasn't happening prior to Oct 1, and I wasn't using my PC from then until the 8th. So there hasn't been any hardware updates on my end that may have caused this issue to my knowledge.

This also only occurs on one PC in the house. The other PCs and phones seem to hold their Internet well and are not experiencing packet loss on the regular. This happens at all times of the day, during peak hours and when I'm the only person actively using the network at home during off hours.

My motherboard is the MAG-X570-TOMAHAWK-WIFI and these are things I've already tried to help fix the issue:

1. Restart the router

2. Resetting IP config and flushing DNS through cmd prompt

3. Update all my drivers to the latest versions (as of Oct 16)

4. Updated my BIOS

5. Uninstalling and reinstalling WiFi drivers.

6. Moving the PC closer to the router

I've been running trying to run ping, tracert, and pathping to www.google.com as a base line. Ping is where I'm seeing some packet loss with "request timed out" and it always aligns to when I get rubberbanding spikes while in game.
Wired connection is working fine - however, I can't have wired connection at the moment since the place it needs to be has no wiring set up currently.

Ive run ping, tracert, and pathping to www.google.com showing consistent packet loss when Ive run the commands a couple of times the past few days.

Trace complete.

The pathping 1% losses differ between runs - sometimes more or less number of nodes - but shows some combination of them.

I've also been running PingPlotter and these are some results from about 5 hours

I would love to have consistent Internet again without all the packet loss spikes. The other working PC is connected to the same network via WiFi, and consistently shows NO packet loss when running ping, pathping or PingPlotter.

Good morning @FThay,

Thank you for being so diligent and posting all of your troubleshooting steps thus far.

Since you've narrowed this issue down to just one PC through process of elimination and the issue does not occur over Ethernet or on any other device, that would indicate there is something wrong with the WiFi module in this specific PC. 

In this case, since you've already attempted to reinstall the drivers, I would recommend replacing your network card in this PC.

Regards,

RogersCorey

@FThay I searched the Internet for "MAG X570 TOMAHAWK WIFI slow" and got a ton of search results.  In one case, a Comcast customer reported poor Wi-Fi performance while connected to their Xfinity gateway, and they "fixed" the problem by putting their gateway into bridge mode and using their own router.  Another person, who has a Netgear router suddenly started experiencing slow throughput and "fixed" their problem by downgrading their router's firmware.

I have a completely different motherboard but had all sorts of problems fixing my Wi-Fi performance issues when using Intel ax200 and ax210 Wi-Fi modules and Technicolor XB7 and XB8 gateways with their Broadcom Wi-Fi chipsets.  I could not get a stable connection.  When I looked at the details about by Wi-Fi connection, I could see the RSSI fluctuating constantly, as did the data rates on the link.

There are times when the Wi-Fi chipsets and drivers on the PC and on the Wi-Fi Access Point do not play nicely together.  When I was an early tester of the XB8, I could only attain something like 230 Mbps on a good day, and experienced a ton of packet loss.  Things got better (1 year, 9 months ago) when we started getting really solid firmware for the XB8.  It took a while longer to get a stable driver release from Intel but when that happened, I was able to attain almost 1.9 Gbps of throughput on a Wi-Fi 6E connection at close range.

What model of Ignite Gateway do you have and how fast is your Rogers Internet service?  Also, can you confirm which Wi-Fi module your motherboard uses?  Given that none of your other devices are experiencing Wi-Fi connectivity issues, it's almost certain your PC's Wi-Fi hardware and drivers are causing the problem.

I have been that exact model of motherboard in my main system since it came out. It has been solid! What WiFi drivers are you using? The ones from MSai or the ones from Intel? If you are using the MSI drivers. Completely uninstall them and install the latest ones from Intel.
You will also want to check the settings for the WiFi adapter. Turn off all of the power saving trash enabled by default and make sure it is set to maximum performance. Make sure your midem's WiFi is set to a specific chamnel and not auto, and make sure your wireless networks are separated into 2.4GHz, 5GHz, and 6GHz to minimize other devices from impacting what that PC is doing.

[FThay]

I'm pretty sure I have an XB8 router, my plan covers up to 1.5 Gbps, but it's a little slower since I'm decently further from the router and on WiFi. I'm just more concerned about the packet loss and stability that seemed to show up out of the blue. As another user suggested, I'll try installing driviers from Intel instead of MSI, if not, then it's more likely than not a hardware issue.

[FThay]

Thanks for your suggestion, I didn't think to try using drivers from Intel over MSI's website. Unfortunately, it didn't help with anything and the issue seems to be the same. The modem's settings on the XB8 are completely locked down so I can't adjust any of the WiFi settings outside of name/password. Might be the WiFi care in the PC after all.
