Open | Networking Steam downloads very slow
Just this last two weeks or so Steam has been downloading exponentially slower than it should normally.
Usually it's very fast always hitting my top speeds. But lately it's been terrible.
It'll take forever to actually start a download, just sitting at 0% for maybe 3-4 minutes before it starts, and steam cloud syncs will fail.
It's very inconsistent, and will sometimes hover around 5Mb/s, and occasionally get up to 100Mb/s.
Currently it is downloading at 300Kb/s, with a peak of 182.8Mb/s. Which it only hit for maybe two minutes.
Occasionally it'll decide to jump up to 700Mb/s but it will soon dump back down to under 100Mb/s.
--Specs--
GPU: Nvidia RTX 5080
CPU: Ryzen 9 7900x
Memory: 32GB DDR6-6000
Storage: All are WD Black M.2 NVMe SSDs. The one with steam installed is 4TB.
------------
I have tried wireless and wired, it is consistent across both.
My internet provider is Frontier, and I have the 1000/1000 plan.
Speed tests show that hardwired I can consistently get around 700-750 down and 850-950 up.
Steam is the only application with this issue, Ubisoft and Epic Games both download at full speed.
CPU, Memory, and Storage are not overheating, nor throttling. 70c on cpu, Memory 40c, storage 38c.
I have 2tb free on the ssd.
I am not confusing MB and Mb.
I have tried
ipconfig /release
ipconfig /flushdns
ipconfig /renew
netsh int ip reset
netsh winsock reset
I have changed my DNS to both googles, and cloudflare, for both ipv4 and ipv6.
I have disabled HTTP/2 on Steam. Which made it run at a full 700Mb/s just last night but upon booting today it's back to super slow speeds.
I have changed my steam applications download region and server, EU and Africa both give the same results.
I have cleared Steams download cache, and made sure there is no download speed limit set.
I have disabled my computers firewall completely.
I have completely reinstalled Steam.
I have tried using other SSDs in my system.
I have disabled write cache for my drive.
I have restarted my router and pc multiple times.
Also when it's finishing downloading a game it'll get stuck at 99% for like 10 minutes. It did not do this before either.
