I219-LM disconnecting

[Weathermin8]

Im running a minecraft server on my Prodesk 600 G4, and it is having this issue. Sometimes when someone teleports it will disconnect the computer from the internet. On the device manager it's saying that the ethernet is connected but there's no traffic. The server doesn't crash or anything, it's just the computer that disconnects. I tried asking for Intel to help but when they ran out of possible solutions they recommended i come here.

Below are some images of the issues I've found so far that might cause it

Disconnect from internet but no errors in device manager is symptom of driver or modem problem

I assume you have the tower versions of the 600 g4

A bios release came out last month and the "fixes" listed Realtek which I suspect is your network

https://support.hp.com/us-en/drivers/selfservice/hp-prodesk-600-g4-microtower-pc/21341167

Network drivers are listed both for Realtek and Intel so it is not clear which network card or adapter your system came with

What is your product id?

I actually have the mini desktop.

My product ID is 4FZ41UT#ABA

That product ID shows the following specs

You probably have one of the following

---

Intel 9560 802.11ac 2x2 with Bluetooth M.2 Combo Card vPro

Intel 9560 802.11ac 2x2 with Bluetooth M.2 Combo Card non-vPro

Realtek RTL8821BE 802.11ac 2x2 with Bluetooth M.2 Combo Card

Realtek RTL8723CE 802.11ac 1x1 with Bluetooth M.2 Combo Card

Since you have windows 10 make sure you have the win 10 bios dated Aug 15, 2022

https://support.hp.com/us-en/drivers/selfservice/hp-prodesk-600-g4-microtower-pc/21341167 (select win10 )

Please look  in the device manager and see if you have the intel wifi or the realtek wifi

If intel use driver https://ftp.hp.com/pub/softpaq/sp138501-139000/sp138639.exe  (Mar 2022)

if Realtek use driver https://ftp.hp.com/pub/softpaq/sp140001-140500/sp140207.exe  (july 2022)

Please update the WiFi even if your server is using hard wired ethernet

The hard wired ethernet drivers are intel "nic" https://ftp.hp.com/pub/softpaq/sp140501-141000/sp140671.exe  (jun 2022)

Alright so I downloaded and installed everything and it still is giving me this issue. It seems to be happening most when there is decent amount of stress on the server

Try the following at the device manager's hardwired ethernet adapter

Power management - do not let system power it off

Device properties: disable energy efficient ethernet

if the above does not help try the following.  Note that Offload enabled means the NIC handles the task, not the CPU.  Some chip designs cannot keep up with the workload and your modern CPU may do a better job.

Try disabling the Checksum offload first then the other offloads

You can try enabling or disabling the jumbo frame.  Normally it should be off

Shutting off the wake on line or wake on pattern match can reduce the burden of work for the NIC

You can look at your modem for broadband errors

Try some speed tests to see if improvements above make a difference

and you can use https://www.speedtest.net/

Even if not using Wi-Fi you should check for problem as degraded Wi-Fi indicts a modem problem.

You should be using cat6 cabling for your Minecraft server.

Nothings working. I've tried everything twice now and it's still happening. I'm debating buying a new download of windows 10 to another ssd and putting the server files on there.

Try drivers from Intel for the i219-LM device

https://www.intel.com/content/www/us/en/products/sku/82185/intel-ethernet-connection-i219lm/download...

Use the non-pro drivers, I am guessing the pro are for enterprise distribution and do not apply to you but this is a gues

Your upload speed is important when running a server.  What did those speed tests show and how did they compare to the following requirements

https://minecraft.fandom.com/wiki/Server/Requirements/Dedicated

Rather than replace HDD with SDD you might try a disk cache software.  Primo is free for a month and I used it on an Areas51 and on a Z400. You will still have to add an MVMe SDD in one of the m.2 slots or specify that Primo use part of the existing m.2 SDD to speed up the HDD

My kids ran a red faction server for a while but  other players notice they had no lag and and stopped using their server.

My upload speed is good. At 64 mbps upload and 5 mbps download it meets recommended requirements.

I donwloaded everything and its still happening. I assume it has to be my internet somehow
