Sometimes, if a friend adds themselves to my Minecraft game, it breaks my connection and makes things go wrong.
Sometimes, if a friend adds themselves to my Minecraft game, it breaks my connection and makes things go wrong.
I decided to set up a modded Minecraft server for my friend. The internet worked fine at first because I could join from outside. But right after that, my ethernet connection started crashing. I can't turn off the adapter, and the computer stops even when I try to run the repair tool. The only way to fix it is a full restart of the PC. This problem happens exactly every time without any other issues before or recently. That feels weird because I used to have this exact setup for a Dyson Sphere Program server about a month ago, and Minecraft servers on the same motherboard worked perfectly then too. Do you guys know how to troubleshoot this? Maybe there are specific tests to run that could give me more info so I can figure it out? My computer is built with Windows 10, a Gigabyte X570 AORUS PRO WIFI ATX board, an AMD Ryzen 7 3700X processor, and a RTX 3060Ti graphics card. It has four sticks of RAM. I had this problem for two or three years already. Sometimes my USB power gets cut out randomly, so sometimes I also had to turn off the XMP setting because my computer started crashing on startup (BSoD). That feels like it could be the main reason. After checking some online forums, people keep talking about faulty ethernet adapters that shut down as a safety measure if they get too much traffic from outside. Does that sound like what is happening here? Or is everything just failing because the motherboard itself is breaking down? Any help would really mean something to me. Thanks!
I assume if you try to run some fixes, your computer will reply to commands and let you see things. I guess you can stop the minecraft server code even though it isn't connected yet. It's hard to tell what the troubleshooter is doing; it would be nice if it showed the commands it tried instead of just doing them. Do you see any errors in the event viewer? Can you run simple commands like IPCONFIG /all? Is the ethernet port turned off or does it look active with a proper IP address? If everything looks good, what happens when you try to ping your router's IP? I've never heard of an ethernet port turning itself off because of traffic. That sounds like a bad idea since someone could use that disabled port as a denial-of-service attack on any network you can reach locally. When I checked if you had 2.5 or 1gbit speed, they bundled CFOSspeed with that motherboard. That program causes all kinds of strange problems; I've never heard it hang the machine but I would uninstall that software. It's unfortunate that forcing a failure isn't much simpler. If for example you could boot a USB linux image that also had issues, you might suspect a hardware problem. In any case, a pcie ethernet port is pretty cheap to replace.
I don't see CFOSpeed on my screen or in the system, so it probably never got installed here. The problem only happens when my friend logs into their server instead of me, so I can't really test this right now. Let's try again later and check what ipconfig shows up as well as a router ping. A good chance is that swapping out the PCIe ethernet card would help, but since I already have problems with the motherboard, it might be easier to just buy a brand new one instead of fixing these upgrades. Could it also be because of memory? I did buy two separate RAM kits back 1-2 years ago and tried really hard to match them up by same brand, model, speed, and timings. I installed the second kit about a year ago, but everything worked fine until my computer started BSoD-ing a few months ago when XMP was turned on.
Get something like memtest86 and run it for a while. People use it to check timing settings but it finds bad memory all the time. Bad memory usually makes things slow down or make computers crash. I'm not really good at fixing motherboards, so I don't know if there are tools that will tell you what's wrong.
"Ports seem like they are working because the computer can talk to the server, but right after that happens, my internet connection stops working fast." I'll tell people to check Reliability History and Event Viewer in Windows for error codes, warnings, and any messages that come before or when the crash happens. These tools give more details but they might not help much if there are no errors to find. The next step is harder because it needs a computer with lots of memory and good CPU power. Use Task Manager and Resource Monitor (use both, but only one at a time) to watch how well things run on the system. First, check while the machine is working normally. Then ask a friend to join in. See what happens... Hopefully you'll find something that leads up to the crash. It will take some trial-and-error testing and lots of time and effort. And you need someone who wants to help. Be careful when trying things out: change only one thing at a time. Tell us about what you see.
I ran a memtest earlier today and it seems to have passed three times without any mistakes. I also tried making my computer crash right away with a friend, then looked at the ipconfig settings, and the Ethernet card showed up as usual, just like it normally does.
Honestly, I'm completely lost on what I want here, so I'll attach my event viewer and reliability history logs to this reply. Hopefully someone smarter than me can figure out what is happening. Also, did not notice anything too weird in the task manager or resource monitor - except for my ethernet traffic spikes when my friend connected to the server. Actually... there doesn't seem to be a file upload option? I have a Google Drive link here, but most people don't like downloading stuff from random folks lol: https://drive.google.com/drive/folders/1...sp=sharing If there is a better way to share them with you, please let me know.
Take pictures and put them on imgur at www.imgur.com. Also, send me your router ping results here.
Reliability history didn't appear to show anything (the crash occurred around 9:37 pm), and I'm not sure which logs to show for Event viewer. Upon trying to select everything, it just crashes and says the input is too big lol. Any idea which logs I should select? Also here's router ping, ipconfig (not sure what is safe to show lol sorry), as well as task manager during the crash (the big spike is when they first connect I believe).
