⚠ Disable IPv6 protocol ASAP

[GR-BlacK||KnighT]

Recently, I enabled Ipv6 protocol from Network adapter settings and made use of it with the automatic default ipv6 addressing from windows 10 control panel settings.

I had no problem for a week with all softwares and downloading or browsing content until steam started to updating games.
I got a limited cap of download speed to 1.2MB/s while I have 8MB/s on all other applications except steam.

I recommend to all steam users to disable the ipv6 protocol from network adapter settings within the windows control panel because it seems steam forces ipv6 protocol over ipv4 when both are enabled and eventually it has a download speed throttling due to several bugs.

If any similar issue occurred to anyone please comment this post.
If someone knows how to solve this problem, please speak your mind.

Help is needed asap from steam devs

THANK YOU!
Last 2 weeks had problem with it.
Took me some time to realize it was because of steam.
Same for me, when steam started to download anything, it made DNS crash which made all devices at home not be able to use internet, even my pc which uses ethernet cable couldnt, only one funny thing was that even if steam continued to download with much lowered speed compared to my internet's max speed, rest of steam's features couldnt connect to internet either
But tried turing off IPv6 and it worked, in a sec got full download speed and can browse internet on my phone.

Thank you really much
Hope more people will see this one

This bug exist over a millennial and Steam devs can't even fix it somehow. So the best solution is to turn off ipv6 addressing module from your net adapter.

Are the people that have seen and experienced this issue still being ignored and this issue being treated like it is not a thing?

If I have IPv6 enabled on my NIC(Windows 11) it will sometimes tank the internet for EVERY SINGLE OTHER DEVICE in my house wired or wireless, while using nowhere near the max amount of bandwidth I have. This just happened again so I finally had to dig a bit.

Near as I can tell it's been an issue for years and just ignored, but one solution suggested that seemed worth trying.

Turning off IPv6 on my network adaptor fixes this problem. I can have downloads going fast, and it stops murdering my network. I agree with the theory in this post that the way Steam does things in the back end is F'd and if you have IPv6 enabled it tries to send it as IPv4 causing a tons of problems which is what is tanking your internet hardware. I don't understand networking enough to try to explain it beyond that, but with what I do understand, it makes some kind of sense.

It sounds like Steam is the one that needs to change or update something on their back end here. Disabling IPv6 is not a good solution long term.

I will recommend against it. In west europe ipv6 is widely used as the IP. We connect to websites using ipv6 and they id us with ipv6.
Yes most ISPs currently hand both an IPv4 and IPv6 option, but its clear ISPs are trying to hop over to IPv6, at least over here.

If you live over here I don't think you'll encounter connection problems or download stability.


Edit to note:
Yes there are a number of people who noticed their connection experiences with the steam client, improve when they disabled IPv6.
One commonality I noticed for those is that they also get the Steam Client connected through the Akamaized CDN.
So I wonder if that is related.

With latest steam client beta am seeing steam loose connection. It just freezes with white background to client window as it tries to reconnect to steam backbone. There are definitely server side issues as well as steam runtime issues client side. Only Steam looses connection. Windows os still has internet connection and not local network issue.

This thread highlights many issues are occuring here in western europe causing huge latency and timeouts - both game breaking issues.. https://steamcommunity.com/groups/SteamClientBeta/discussions/3/3763356482612086141/
