My xbox one is updating a game (COD) and the download speed is 2.99 mbps. When I speedtest...

I have no issues with connecting to xbox live. I have done i speedtest the results where Ping = 42ms,

Download Speed = 9.76 Mbps

Upload Speed = 0.68 Mbps

Your upload will always be lower then yoir download

You have to contact your isp to find out your upload when you see 1gbps

That's just download. And at giga bit not giga byte

1000/8 is your true download speed and yes wifi and distance from the data Center affects your speeds

When testing on speedtest you gotta remember it's your connection to the speed.test servers not xbox

And speedtest. Isn't your download speed at mBps

That's your mbps

Just a bit more information, as I was typing out my Original post I was also downloading a 1410 Preview update on my Xbox One.

While the update was downloading I ran a speedtest at www.speedtest.net. It showed my ping at around 245ms with download speeds at 2.5mbps upload speeds at 0.80mbps.

Now that the update has finished downloading my ping is now back to 19ms. Download is back to 16.25mbps and upload is back to 1.25 mbps. Yes I have crappy speeds, but I have NEVER had this problem with Xbox Live.

Still not solved

Same issue here:

Xbox One:

Download Speed: 86,34 Mbps

Upload Speed: 94,03 Mbps

Packetl loss: 0%

MTU: 1480

Latency: 148ms

I live in Amsterdam and location is set to United Kingdom

Now let see what speedtest say:

Amsterdam

Download speed: 86,21 Mbps

Upload speed: 94,82 Mbps

Packet loss: 0%

Latency: 4ms

London (by Vodafone UK):

Download speed: 87,10 Mbps

Upload speed: 94,42 Mbps

Packet loss: 0%

Latency: 12ms

Online gaming is no issue, but streaming to Twitch results in a laggy stream...

I’ve been noticing very slow download speeds on my Xbox Series S. I have a fibre network connection, and ran a speedtest showing around 950 MBps download and 950 MBps upload. When i download a game or app on Xbox, that number drops to around 50-100 MBps. It sometimes gets to 350-400, but it’s rare. Are the microsoft servers just slow?

Where did you perform the througput test? On your Xbox?
