Internet crashes while hosting a server locally (with lots of block changes)
Hello, I've hosted a server for years through a hosting service and have been looking in to building a dedicated machine to run in my home. I've been running tests on my PC before doing so and have run in to a problem I can't find a straight answer to.
I can get the server up and running, as well has having players connect without issue. However, after I try to stress test the network by either generate a lot of chunks, or lighting a bunch of TNT, the internet on my machine stops working. When it happens, it's like my upload speed stops first. Other devices in the home connected to the same router via ethernet and wifi have no issues. While watching the network portion of my Task Manager, "Send" immediately goes to 0kbps while "receive" continues to have indicate data is transmitting. While in Discord voice chat I can hear players who were on the server say "it crashed" but they can't hear anything I'm saying. After a moment the entire internet connection on my PC stops working all together. Someone mentioned it could be a bandwidth problem, but I'm not sure how I'd investigate that. The plan with my ISP allows for 20mbps up, so as far as I know that should be enough.
The only way to get my internet working again is to restart my entire PC. Does this sound like it could be a problem with my network/ISP, or perhaps just my modem? Or could there be some setting I'm overlooking in the server config files?

There was a known bug with certain Intel NICs that was causing this. Try to manually set the speed of the nic to be Gigabit instead of 2.5Gbps
@Azander
What's a NIC?
(sorry I can probalby google this)
No worries mate, its the network adapter in your pc
Gives you internet
Cool, thank you, I'll do some searching on how to do this 🙂
I was able to find the option to change the speed value on my NIC. It was on auto, but do you happen to in order to make it gigabit? The top option probably?
1.0 GBps Full Duplex
Awesome, thank you for your help! I'll give this a try 🙂
Np, ping me if it works
Oh and you do have the Intel NIC
I can see at the top
ye that should fix it
Sweet, I'll let you know in a few hours when I get home if it work 👍 ❤️
If it requires PC restart it’s not ISP or your modem pretty much guaranteed, I think Horus might be onto something
Thank you, that's good to know. I've got a new modem/router on the way to see if it fixes it. I've been meaning to ditch my ISPs rented router anyways lol
No luck. I lit a few thousand TNT with another player on the server and it still disconnected after making that change
Though, I didn't think to restart my PC before trying the test
I know it's a known bug, not sure if my fix is 100% gonna support the kind of load you're doing tho
If you just Google "Intel i225-v minecraft" maybe someone has found a better solution
Sounds good, will do 🙂 If there's too much load on a server could it crash any machines connection like that I wonder?
The i225-v bug is centered around outside connections basically overloading it with not much data and for not much reason
It's the only chip I've heard doing that
A perm fix would be a new network card, like a internal pcie one
Or moving to a host, free ones like Google and Oracle exist as well
Awesome, thank you. Not that it's related to this post, but I'm ultimatly trying to test my network before building a dedicated machiene to keep at home. This connection error has scared me in to buying all the pieces of the machine but if I can be confident it's my hardware causing the issue that makes me happier
Looks like a network card is only $20, if I really want to test my network before building it, I could just get one to put in my PC first I guess
Yeah they're cheap and easy to install, and not as cumbersome as swapping the motherboard for a different onboard nic
You just got unlucky with the Intel issue
