Is The Xbox One Gigabit Port Artificially Rate Limited?

I've been wondering for a while why I don't see speeds above 100Mbit on my Xbox One. When I first got it, it made sense, since I had it hardwired to my Wireless-N router that only had 10/100 ports, and I had a 150Mbit internet connection and even regular
PC's and such on Wi-Fi tested out around roughly 100Mbit.

About 18 months ago I bought a Linksys EA6500v2, which has gigabit ports, but still had the same 150Mbit internet connection. So at that point I was figuring with TCP/IP overheard, network congestion, and such that hitting right around 100Mbit was about
right. Even of my Wi-Fi devices it rarely hit much above the 100Mbit mark.

Now fast forward a bit more and I've upgraded to a 200Mbit connection that tests out fairly close to 200Mbit on Wi-Fi, and Linksys also sent me the new EA8300 just a couple weeks before the public release to test out and keep. So far it's been a pretty decent
AC2200 router. One of the changes to the EA8300 is a reporting function built into the UI that will give me the specs of any hardware connected on the Ethernet ports, including supported speeds.

According to the EA8300 the Xbox One is reporting that it's only capable of negotiating a 10/100 speed. I've hooked up other hardware that is 10/100 and 10/100/1000 and so far it reports every other device correctly as far as the listed support.

So is this a case of an issue with artificial rate limiting in the firmware or should I be seeking a replacement console via my local Microsoft Store or via support?

:)

 

Install disc on usb, play disc on int hdd?

SATA2 maximum transfer rate up to 300 MB/s

USB 2.0 maximum transfer rate up to 35 MB/s artificially limited to 16MB/s by xbox itself due to rest of the throughput reserved for kinnect and other USB ports. There is a reason why Rockstar mandates installation of the first disc on hard drive and its
called bandwidth.

 

Ethernet not Gigabit!?

Ok I've had my XBOX one for a few months now connected to my Gigabit network and am convince that Microsoft has falsely advertised the console as having a gigabit Ethernet port. Every device in connected to my 24port Netgear gigabit switch is connecting
at full gigabit speed. However the XBOX One does not. Now when I go into m y Netgear console and look at the connections for VLAN, and other connections this device does not show a gigabit connection no matter what port it is plugged into. How do I change
the settings for the XBOX One Ethernet port? Or like so many other owners am I going to be forced to sell it for a PS4? This kind of false advertising is what causes consumers like me to just give up on a brand!

 

Hey there Mountain Dew,

What happens when you hook the console up to the modem directly and eliminate any devices in between? Also, are you using an original model Xbox One or the Xbox One S? Are you by chance in the Xbox One insider program and testing new dashboard builds as
well?

Let us know!

I can verify that the Xbox One is capable of link speed up to 1.00 Gbps

This sounds like a layer 1 issue, namely the cable itself.

You never mentioned if you were using the very same cable to troubleshoot link speed on different devices.

Make sure you you have at least a Cat 5e or Cat 6 cable connected with your console, and make sure the cable is not faulty.

Don't fall for the patch cable that came with your console. Mine only used 2 pair of wires (100BASE-TX).

 

Note: My post is mainly concerned with link speed and not throughput. Therefore, the speed of the link has nothing to with IP packet overhead or congestion, as these pulses are only sent, from an Ethernet device, when there are no frames being sent or received.

 

I've tried both direct to modem and via the router. It's an Xbox One.

I am in the Alpha Ring.

Speeds test about the same (within 2-3%)

 

I've tested with Cat5, Cat5e. and Cat6. i have tons of known good cables in boxes everywhere.

Purely as a pedantic () FYI Cat5 can do 1Gbit for link, but not necessarily for sustained throughout. The other devices I have that support 1Gbit all link at 1Gbit on all 3 cable types on the same router.

All my cables are 4-pair. I use the cable that came with the Xbox for my Sony home theater system that only has a 10/100 connection and I only use the network functionality on it to check for updates periodically.

BTW guys, thank you both for the replies. I sometimes miss the days when I was MS internal and could just ping a colleague via Lync or ****.

I'll do another direct to modem test run when I have time tonight or tomorrow.

 

Cat5 cable adhere to 10BASE-TX and 100BASE-TX standard. Even though a Cat5 cable can potentially break speeds greater than 100 Mbps, the Cat5 cable itself haven't been tested for purposes greater than what the standard adhere to.

You know, there's an easy way to test the speed of a link through Windows 'cmd'.

If you have 10/100/1000 network adapter on your PC, simply connect an Ethernet cable between your PC and Xbox One.

Bring up 'cmd' and type the following command (or paste): wmic NIC where NetEnabled=true get Name, Speed

The numbers are presented in bits.

 

I know. I just haven't had the time to sit down and do that as of yet.

My router also reports link status though and is reporting it correctly for all other devices, so I was tending to trust it. I'll do that as well once I get a decent amount of time at home (might be able to tomorrow) and will report back in.

BTW (again me being somewhat pedantic) but you might want to re-read the specifications on cable ratings. Cat5 on a 4-pair wire supports Gigabit as part of the standard. It's in the actual standard itself. I just don't trust most Cat5 cables for the throughput.
Not to mention most modern 4-pair Cat5 cables are actually Cat5e, just not labeled as such.

That being said I prefer Cat6 for most things just to be sure.

 

The "Cat 5" standard I'm referring to is the 1995 TIA/EIA-TSB-67 (old class D), which is certified for data rates up to 100 Mbps. It may, or may not, support rates up to 1000 Mbps.

If the cable you are using is labeled, as according to the 1999 TIA/EIA-TSB-95 (new class D) standard, than, regardless if it reads "Cat 5" or "Cat 5e", it's an enhanced version of Cat 5.

Prior to TSB-95, return loss and The Equal-Level Far-End Crosstalk (ELFEXT) were not defined for performance specifications, which also depict the old class D standard.

So, even though your Cat 5 cable can outperform speeds greater than 100 Mbps, it shouldn't be said that all Cat 5 cables (according to the TSB-67 standard) will.

Back to where we were before you had to drag in Cat 5 into the picture, how did the test go?

 

I believe we can close the thread. I'll just ping some friends from my days with Xbox.
