I was able to resolve the issue by using a different router. There are some other settings in the old router like “NAT filtering” that I didn’t try changing.
What kind of Router did you have before? Because i’ve been wondering if its my router, but It seems odd that it only effects Starcraft2, and my current router is pretty new.
We’re seeing some reports on the same problem with Comcast and Spectrum users. We’re tracking this issue on our end since most tests are coming back as completely clean, which may be related a specific router or chipset for the router that we’ll want to keep track of.
@minkcv, would you happen to have your old router model to provide? Also, what’s the new router model?
@ PhoenixMW, could you provide the router/modem that you currently have? Could you also check if the QoS/WMM/UPnP is enabled and see if disabling this helps?
[Edit] It looks like these reports are happening with Netgear routers. The information requested above will be greatly appreciated so that we can confirm the trend we’re seeing with Netgear routers 
Yea my Router is a Netgear WNDR3700v5 — N600, which I tried to update its drivers, which I did but it appeared to have no affect. Id also like to note that my set up is Wired… Straight into the Router. I would test it into the modem but the modem only has one ethernet slot.
Btw, I made a Forum post where I listed all the forums that seem to be having the same issue, from atleast Oct 2019, before idk if there were any posts. I made it because ive been playing with this bug from atleast around Dec 2019. Which ive just been putting up with, because its so random I couldn’t figure out a solution.
Heres the link to it
A long series of Attempting to reconnecting Forums and issues that seem unresolved - #3 by Leviathan-1945
Thank you so much, PhoenixMW! I’m adding the model over to our tracking and checking out your post
For anyone else experiencing this issue, please include the following:
- Does enabling QoS help at all?
- What is the router/modem model?
- What internet provider are you using?
We have seen QoS issues with Netgear routers in Overwatch PvE, which enabling the QoS helps with. We are seeing this trend with Comcast and Spectrum at this moment, but the title has been updated to reflect this with netgear routers in case we can find a consistent trend.
Yea idk, I’ve haven’t tried messing with the QoS or anything like that, but that is because I’m not a Tech guy, or at least not a networking one. Which is why I tried to just ignore the issue, and just try to win all my games under 5 mins.
I’m glad you guys found that list helpful, I found it kinda weird how all these forms had the same issue, but no one ever gave a for sure solution.
Though, I would like to note, my issue is new, like for me Dec 2019, which fits the timeline that I put into the other post. Because before hand, I’ve had Spectrum/Netgear with Starcraft 2 and I cant recall having this bug at all.
However, online i’ve found some older posts when looking up Starcraft 2 and attempting to reconnect from around 2014 (if I remember right). They seemed to also have the same issue, and their solution was some sort of port forwarding to specific ports.
We just started seeing this trend recently since folks are returning back to the game. We’re still gathering information and what helps in the mean time The “attempting to reconnect” issue is a generic message since it can be caused by other connection issues, so old posts will exist though the issue may be different.
In this situation, we have seen a consistent trend in reports along with the same description of disconnecting within 5 minutes, which matches up with how mitigation tends to work. Ports likely wouldn’t cause the specific disconnections after 5 minutes, but there is a guide on this external portforward website if you wanted to give it a try.
We’re gathering ticket reports along with forum reports so hopefully we’ll see some additional reports here. I’ll update here if we find anything new with our ticket reports
Hey I am having the exact same issues. Give or take around 5 minutes into the game I have the attempting to reconnect message pop up. Sometimes this happens every game, or sometimes I get multiple games before this occurs.
I am using a NetGear router.
I have a direct wired connection into my computer with a brand new CAT 6 cable.
I tried to set up a Qos on my router but have no idea if I did it correctly… the game dropped the first game after I tried to set it up, so either it didn’t work or I did it wrong.
I should note that I have no issues playing BF5, or watching videos or streams. This appears to be an issue only with Starcraft, although I could have just not experienced the issue with other things.
This has been going on for months.
Thank you, Bairdo, for your report! It looks like this might be happening with other ISPs other than the two we’ve noted. I’ll add this over to our tracking for this issue!
Could you provide the Netgear model that you’re currently using?
Also by chance, does disabling the audio help with this issue? It’s an odd workaround and not ideal, but the audio bit can impact connections at times.
I am using a Netgear AC 1750 (R6350).
I just dropped out of my last game. I will try the no audio and see how it goes.
My internet provider is Execulink.
Just an update. A while back I changed my audio setting in game from medium quality to high. Just changed it back and so far so good. I will report if the problem happens again.
Ok that did not solve the issue.
I am having the same issue. Starcraft has become unplayable as I disconnect from every game I enter. I have a netgear router r6220.
Thank you for giving that a try, Bairdo! Have either of you tried toggling the QoS setting mentioned above? Either by enabling or disabling the setting to see if it may help?
I tried it with no apparent success. I will try again. The game disconnects are other times too. The last game just disconnected at 15:30.
Thanks for giving that a try, too, Bairdo! We’re tracking for more reports on the issue and what else might be causing the constant disconnections. If there’s anything new that comes up, I’ll share it here!
This is not ideal by any means, but the only resolution that I’ve personally seen with this issue is by replacing the modem. Hopefully, this won’t be necessary if we can find a different fix for this.
