Hello, I am having a difficult problem with my computer. For almost a year I have had no problems with the ethernet connection for my computer, but for the last two weeks I have been experiencing packet loss on both ethernet and wifi connections. I have also tried connecting (only via wifi because it is my only option) to a different network and the packet loss still occurs. It's very sporadic and can last for over a minute. The other devices on the main network work fine and it's isolated to my computer

I have tried; updating drivers, uninstalling drivers and reinstalling, uninstalling device and reinstalling, updating drivers from motherboard manufacturer website, restarting the router, a different port on the router, both ethernet and wifi, a different network, windows troubleshooter, disabling ipv4 and ipv6 separately, anti virus, disabling power management options, disabling qos packet scheduler, I believe one or two other things but I do not recall at this particular moment I am sorry. Every speedtest results normal speeds, and I've had pingplotter running, which I don't quite understand but I can see that every target has packet loss across almost every hop. I'm truly stumped, and I am going to be beginning classes soon and would very much like to be able to do them.

If anyone has any advice or knows what else I could try, please feel free to let me know. I do not understand networking all too much, and I have tried every solution I have come across on google and here for the week or so. I feel so defeated!

System hardware is B550M Mortar, Ryzen 5 5600x, EVGA Geforece Gtx 1070ti ftw, 16gb hyperx ram, 1tb Samsung 980 m.2 ssd with 120gb available, Corsair RM750 power supply (probably 3 years old, original to build and well maintained), my os is Windows 10 Home and is build 19045.5737. I have a usb mouse and keyboard and occasionally a usb headset, display port leading to my monitor, and a set of speakers that attach to the monitor with 3.5mm. Every driver is up to date as well as far as I know

Thanks :)

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition (original to build, new, refurbished, used)?

Disk drive(s): make, model, capacity, how full?

List all attached peripherals.

So if it really is only your computer then it should show loss between the pc and the router. If the problem was the router itself or beyond the router you would think it would affect other devices.

So I would first start with a simple constant ping to the router IP address. On ipconfig /all you should see it as your gateway ip.

It should in theory cause loss here. If it doesn't then it is even more likely it is some kind of software interfering with the data path. You could then try constant ping to 8.8.8.8. I would hope you see loss here. If not then you have some really strange issue that only affects certain kinds of traffic like say HTTP but not ping traffic.

The only reason for the ping is because my next recommendation is to boot a USB linux image. It will run from the USB stick so it does not impact your windows install. Although the ping command has slightly different options under linux it is pretty much the same test and can be done without installing any other software. Your goal here is to determine if the problem is some hardware issue or is some issue with the windows os or some other software installed. If you get ping loss under linux then you start to suspect bad hardware but I don't know what can affect both wifi and ethernet

Unfortantly in most cases all it does is prove it is windows fault. Finding out what in the massive pile of crap microsoft setting takes a lot of effort. You have already done the main things I tend to recommend like disable IPv6 and QoS software. At some point you get frustated enough to just reinstall windows being very careful no other junk is being installed. Be very careful with motherboard and video card firmware that comes with the device. It many times has other bloatware. The one that causes the most issues are the so called "gaming" network acelerators so be sure not allow it to install any of those.

A added idea although not very likely. Maybe there is some setting that in the router that is limited traffic for you mac address (wifi and ethernet would be different). Something like a firewall rules or partenal control setting.

Maybe factory reset the router. After that only set the wifi and admin passwords. I would disable any so called virus or firewall features if they are on by default. You basically want the router running NAT and not much else.

Thank you for replying. I found the gateway ip and am running pingplotter for it, the results yield an average latency of 1.2 and has a constant 100% Packet Loss. When I ping 8.8.8.8, I notice ~30% packet loss on all hops besides hop 11 which is *'d out with 100% Packet Loss, and hop 7 which is around 75-95% packet loss. I hope this information helps, I'm sorry that I do not know more

Do not use pingplotter use a actual ping command. It would be very rare that a router in your house will not respond to a actual ping command. Pingplotter is doing something different and I have many times seen it claim 100% loss which is impossible if you can even see nodes past it. Problem with pingplotter is people go "red bad must fix" and don't really understand what the tool is doing and why a lot of the results are not really valid. In addition pingplotter has to be telling even more lies. You say other devices are not affected. Since they all share the same path all device would see the same loss so something is not correct.

It all doesn't really matter. Even if say hop xx actually losing 50% of all the data passing through it you can do nothing about it. This is some router that is owned by some ISP that you likely have ability to even contact since you do not buy services from that ISP.

All you have control over is your router and your PC.

The only reason I meantioned ping of 8.8.8.8 was in case you see no loss to your router ip. That in theory says your pc is fine and your router is fine....but we know you have actual loss.

Again use simple ping commands since installing ping plotter into a USB boot image is not beginer thing. It is very easy to download the prebuild USB boot images it can get tricky to add software to one of these boot images.

So maybe cut to the end and reinstall windows. It likely will fix the problem even if you never learn why or what was messed up.
