Onboard ethernet dying after sudden +200Mbit spikes
7 replies, posted
I am so sick and tired of this and if I even attempt to google for that problem all I get is unrelated problems or sites being all like "don't use wifi and have no virus ok thanks bye"
To keep things short, this pretty much only happens in VRChat for some reason. The game constantly has to download stuff from their amazon servers, things like avatars and stuff. Thing is this ONLY happens after joining a world aka when the game starts downloading avatars. I assume the game opens a shitton of connections and my onboard ethernet just dies and stops sending or receiving packages.
I've tried limiting the download speed to around 50Mbit using NetLimiter which should be plenty for that game but it still occasionally happens to kill my internet. 95% of the time it gets back up by itself and starts working again after like 15 seconds of waiting, but it also happens that I just get a "no connection" error which forces me to restart. It's a bit less frequent but still even more annoying.
Things I've confirmed so far:
The router is not at fault. When trying to open the config page after the problem occurs it won't load on my pc, but the page loads on my phone and the internet everywhere else in the house works fine.
The cable has been put down here by myself but it's CAT5e and I've actually been officially trained in doing that so I trust my own skills and knowledge (especially after testing it with the tester) that the cable is not at fault. I haven't tested a factory made cable yet because the distance from the router to my pc is too long but once I get one I'll do that just in case.
My PC is clean and up to date. I'm not that illiterate.
This is how it looks like in the task manager when it happens. The graph doesn't bother with single sudden spikes but the stats in my router showed me it went the full 250Mbit which we are paying for. Hope it's obvious that after that spike happens there's nothing being send anymore.

Here are the network devices I have installed. Don't know why I have this WAN shit so that could be the cause but I would need to find what made those show up first and maybe remove it with that.

My way out of this is to get one of those usb to 1Gbit ethernet adapters for like 15€ but I want to avoid additional costs for now.
Thanks.
Can you check your router firewall logs? Or Windows event viewer logs? Perhaps one of them are detecting the spike as a DDoS attempt and is trying to counteract it somehow? Especially if the traffic is coming from multiple sources, instead of just one (like speedtest.net).
Try doing the same thing while pinging a local network device.
ping -t fritz.box
This should work for you. If the ping functions normally even during the spike, the issue could be related to the game starting too many downloads at once, therefore running out of external ports (which is especially an issue if you're under double NAT).
The windows even viewer log is actually a good idea, didn't think of that for some reason. My router is here not at fault because it doesn't block the traffic from one or multiple sources, if anything maybe it is doing that but in the reverse as in it blocks all traffic to my PC but keeps the rest of my devices free to do anything. That would be a bit of a weird way to tackle the issue though, because in my special case I use my phone for vr and have that get a video stream from my PC over the wifi to my phone. Its ghetto and weird but it works and the connection only dies at my PC so idk.
I can try it but if chrome takes forever to load a router config page because it cannot find the host I'm not sure what will happen. I'll try it anyway next time it happens again
Also I've noticed today, I had it happen again but I didnt read your replies yet so I couldn't test further, but a weird thing happened when I opened up the task manager during that. For a few seconds it couldn't load the network graph and it was just blank until it eventually refreshed and popped up again. Dunno why it did that
In addition if nothing else works or gives me a clear solution I will set my network to be 100mbit instead of 1gbit inside my router which can change the mode for each ethernet port there. I wonder if that will help.
If all else fails right click your Realtek adapter and "Uninstall device". Don't delete the drivers if given the option though. Right click at the top of the tree of this menu and "scan for new hardware" and the drivers should automatically re-install.

Might be worth downloading the device drivers from your motherboard manufacturer's website beforehand in case it can't find them again and you're stuck without an internet connection.
(I have all those WAN miniport devices showing too, so don't worry about those).
Ok so the event log gave me this weird error
The network driver detected that its hardware has stopped responding to commands
So I went ahead and googled it and found issues mostly related to vmware and its network drivers but there was one other guy who said that disabling the energy saving options stopped it from breaking.
I was also pinging my router but sure enough as expected it stopped pinging but it also gave a "generic error" message which was weird. I did uninstall the device and let it reinstall itself like you havoc and that didn't help so idk. If this is really fixed by disabling those power saving options then I don't even know anymore.

For anyone who comes over and gets the same problem where the ethernet just dies suddenly, disable the energy saving control in your network device. AKA do this:
1 - bottom left button there, might be called "details" in english windows, idk.

2 - top right, "configure"
https://files.facepunch.com/forum/upload/483/5d2f5cb7-9004-441b-a055-c8fe794f3b76/image.png
3 - top right tab
https://files.facepunch.com/forum/upload/483/7745ddec-3f2c-43ea-a226-0959e7199d0c/image.png
4 - and uncheck the first box (since it disables the other two anyway)

And voila, the issue is fixed. To make yourself feel better or if it still is crashing, deactivate and reactivate your network device or simply restart your PC, which ever is more convenient.

Thanks man. Glad you got it sorted!
