Attempting to Reconnect / Disconnection Bug?

Technical Support
1

Hey folks.

I have been having some severe issues with StarCraft II lately. I am experiencing extremely high ping spikes (800+ ms) and I frequently disconnect from multiplayer games, where a message displaying the following pops up: ‘Attempting to Reconnect’. I will reconnect after some time and my ping will return to 30-40 ms, but this issue happens every couple of minutes and has resulted in making the game unplayable for me and a frustration for people playing with me.

Now, here’s the thing: I have ZERO issues playing other games. I play World of Warcraft, Total War games, Diablo IV, Warcraft III, Star Wars Battlefront II, and a plethora of other online multiplayer games via Steam and other platforms. I maintain low ping in all of these games and my connection has never dropped when playing them.

My issue with StarCraft II seems to have started when I received a new modem. I am currently using the Hitron Technologies CODA-4589-CGO, which is a modem/router combo. However, I’m not even using Wi-Fi; I’m plugged right into the wall using an ethernet cable. My ISP is Cogeco, I have high-speed internet and I maintain a 800-1000 Mb (80-100 MB) connection. I have read that netgear equipment can have issues with StarCraft II, but I haven’t read anything about Hitron modems or routers.

Interestingly enough, when these ping spikes and subsequent disconnections occur (with a waiting to reconnect message with a surrender option), my internet connection is normal and I have even maintained an online connection in World of Warcraft and other games while StarCraft II has supposedly disconnected.

I have tried renewing my IP address, flushing my DNS, using Google’s public DNS, and attempted to add some TcpAckFrequency DWORD files to my registry, yet nothing seems to fix this issue for me.

This issue prevents me from playing the game online, which is quite sad as it is one of my favourite games. If anyone has any suggestions or resolutions, please reply.

that suggests that you have energy efficient ethernet active. it is always active by default and not compatible with starcraft 2. you need to go to device manager and find your network card, then go on settings and turn it off. one more thing: it some times turns back on after a windows update.

Thank you for the response, I’ll give that a try later today. Interesting that StarCraft II would be incompatible with a default feature, though I’ve never disabled this option in the past prior to encountering this issue.

i do not know why it is like that. starcraft 2 is not the only game that struggles with it however, it affects star trek online as well which is also from 2010. could be that it was made standard after starcraft 2 was released.

Update:

Unfortunately, my adapter does not possess an option to disable EEE. I’m not even sure it is enabled by default. However, I fiddled with a few other settings that could help, such as disabling Large Offset Load for IPv4 and Checksum Offload for IPv6. The issue is still frequently occurring despite these changes.

My network adapter is the Ethernet Controller I225-V, if that helps.

if the option is not on your list, then it is enabled and not possible to disable. most network cards have the option of turning it off however. it could however be that they removed that option in windows 11. i do not know, as i do not have windows 11. microsoft also does not recommend windows 11 for gaming. microsoft recommends either windows 10 or windows 12 for gaming. they told me. they never designed windows 11 for gaming in the first place. i never asked them why however. recommended operating system according to blizzard is windows 10 however. you could try windows 10 compatibility mode and see if that works. you could also search for a solution specific to windows 11. how to disable energy efficient ethernet windows 11.

Howdy!

andreasasp StarCraft II fully supports Windows 11 home/Pro. I won’t delete your comment but I do want to be clear Windows 12 isn’t out yet.

We have seen issues with specific Intel® Puma™ CPUs in the past. If you are certain, this issue started with the new modem with no other changes like a new ISP or was swapped out, troubleshooting a different issue. You may ask the ISP to swap the device with a different model.

If you purchased the device yourself, then consult with the manufacturer to ensure the firmware is fully up to date, and to troubleshoot the device itself.

We should play it safe and ensure you have completed basic troubleshooting following the steps Here. Run a Ping Plotter while playing to capture a disconnect then post the link back here within code blocks:

Thank you.

Any suggestions for my issue? My ping doesn’t even spike every time I experience the disconnecting issue in StarCraft II. According to the in-game interface (ctrl+alt+f), my ping remained between 20 - 40 ms when the supposed disconnections were occurring the last two or three times.

I have not modified my game files, nor do I experience any disconnection issues with any other online game I play. This seems to be an issue with StarCraft II itself, considering that my internet is fully functional when my connection with StarCraft II drops.

Should I be requesting a new modem and router?

I also ran a few packet tests, I’m not sure what to make of them:

Zuvykree’s 2nd paragraph is where the suggestions for your issue starts.

Ahh my bad, I skimmed over the response poorly.

Can anyone glean anything from my pingplotter data? The last share is the most recent issue, which occurred today just a while ago.

Is anyone at Blizzard on the StarCraft II team investigating this issue? This seems to be a StarCraft II issue, considering that I don’t experience this with other games. If it’s an issue related to how StarCraft II interacts with certain modems or whatnot, something should be done about StarCraft II.

Hey Deathborn,

The problem lies in the 3rd party modem so there’s nothing that Bliz can look into.

The issue isn’t just with SC2. There’s been articles written by tech writers because the modems cause issues with many apps. For example,

Comparing SC2 to other apps isn’t a good comparison because not all apps make the same demands of the network.
