LAN PORT DISCONNECTING

[#1]

Did the speed test of the xbox port by connecting my laptop to it ... 

Realtek RTL8821CE 802.11ac PCIe Adapter  72200000

Mean anything ???? 🤷‍♀️🤷‍♀️

[#2]

I noticed with the technical log extract the MAC address for the Xbox changed, looking further it switched from a wired connection on Port 2 to a wireless connection. Was this done deliberately?

Are both the wired and wireless connection enabled?

It might be helpful to look at the Hub Two log, can you export a copy and attach to a post please?

Yes both are enabled - should i disconnect from the wireless network whilst the ethernet is in? File attached 

[#4]

I would only enable the interface you need to use.

I'll take a look through the event log to see if anything looks odd.

Dan.

[#5]

Will do!

Thank you appreciate the help 

[#6]

I see you performed a reset of you Hub so the history goes back to that time.

14:31:20, 05 Apr. Reset button pressed - full factory reset

The xbox does appears to be connected more wireless than wired on the 5th April, but today it has been switching between wired and wireless, so disabling the interface not being used will be a good thing to try.

HTH

Dan.

Edit: - 14:58:50, 06 Apr. System start Button press (PowerButton)

Did you restart the Hub for any reason?

[#7]

Yes I will do that. I have had him on wifi majority of the time as it saves upset when it disconnects mid game but with the open reach engineer coming today I plugged the Ethernet in to show him the issues. Yes that was him rebooting the system after he ‘fixed the problem’

@Sheppy127 

I suggest that your efforts are best directed at the LAN speed flip-flop between 10mbps and 100mbps when this device (AIUI) should be doing 1Gbps.

This thread is interesting ... Xbox One lan port detected as 10Mbps - Microsoft Community

Ok so its sounds like an hardware issue on your Xbox network port ( its very rare but can happen…)

So if you are sure that you did all steps from https://support.xbox.com/xbox-one/networking/connection-solution and if the ethernet cable from the console is detected as 1000 Mbps on your router with another device. Go to https://support.microsoft.com/devices , register the serial number of the console (if not done yet) then raise a repair order.

Looks as though that thread ended with returning the Xbox to the repair centre.  Thus the scenario I suggested previously is not unheard of.

This sounds similar - Xbox Ethernet Connection Fluctuating - Microsoft Community

This is interesting too - Another post about Xbox One S internet speed - Microsoft Community - take the game out of the equation and test the Xbox performance as suggested.

There seem to be many reports of variable performance - Xbox Series X slow download speed - Microsoft Community

I would strongly recommend that you disable either the ethernet or the wifi on the Xbox.  You already have it speed flip-flopping on the LAN connection, the last thing you want is a different network connection for it to flip-flop with.

You suggested that you have another Xbox - is it the same model?  When that is connected to the same ethernet cable so you see the speed changes in the router log?  (See the "Wire Lan Port 2" log entries).

Another observation worth taking a look at is the Xbox's nessing around with its MAC address - it is the same for both the LAN NIC and the WiFi NIC - these are hard ware devices, so they should be different ... unless the Xbox is messing with them.  I seem to recall that a couple of the above threads recommended disabling MAC address spoofing.

@Townman 

The log file I viewed the Hub thinks the Xbox has disconnected

16:09:15, 06 Apr. Wire Lan Port 2 up, Speed 10 Mbps
16:09:12, 06 Apr. A device disconnected from Ethernet port 2
16:09:12, 06 Apr. Wire Lan Port 2 down, Speed 10 Mbps
16:09:11, 06 Apr. A device connected to Ethernet port 2
16:09:11, 06 Apr. Wire Lan Port 2 up, Speed 100 Mbps
16:09:09, 06 Apr. DHCP device Disconnected: 192.168.1.115, 28:16:a8:f4:b4:3d, XBOXONE
16:09:08, 06 Apr. A device disconnected from Ethernet port 2
16:09:08, 06 Apr. Wire Lan Port 2 down, Speed 10 Mbps

Another example

15:26:57, 06 Apr. Wire Lan Port 2 up, Speed 10 Mbps
15:26:54, 06 Apr. A device disconnected from Ethernet port 2
15:26:54, 06 Apr. Wire Lan Port 2 down, Speed 10 Mbps
15:26:53, 06 Apr. A device connected to Ethernet port 2
15:26:53, 06 Apr. Wire Lan Port 2 up, Speed 100 Mbps
15:26:47, 06 Apr. A device disconnected from Ethernet port 2
15:26:47, 06 Apr. Wire Lan Port 2 down, Speed 10 Mbps
15:26:45, 06 Apr. A device connected to Ethernet port 2
15:26:45, 06 Apr. Wire Lan Port 2 up, Speed 100 Mbps
15:25:47, 06 Apr. A device disconnected from Ethernet port 2
15:25:47, 06 Apr. Wire Lan Port 2 down, Speed 10 Mbps
15:25:46, 06 Apr. A device connected to Ethernet port 2
15:25:46, 06 Apr. Wire Lan Port 2 up, Speed 100 Mbps
15:25:33, 06 Apr. ARP [del] br0 192.168.1.115 28:16:a8:f4:b4:3d
15:25:30, 06 Apr. DHCP device Disconnected: 192.168.1.115, 28:16:a8:f4:b4:3d, XBOXONE
15:25:29, 06 Apr. A device disconnected from Ethernet port 2

So for whatever reason the Hub sees the xbox disconnect, to me points to an issue with the either the network cable or the xbox  network interface (NIC)

What is noted that the device never negotiates a speed above 100Mbs which it should, again points to the xbox, unless there is a setting to set the network card speed.

For an experiment I disconnected a device on my hub and this is the sequence of events

19:37:38, 06 Apr. A device connected to Ethernet port 1
19:37:38, 06 Apr. Wire Lan Port 1 up, Speed 1000 Mbps
19:37:31, 06 Apr. DHCP device Disconnected: <ip address>, <mac address>, <hostname>
19:37:31, 06 Apr. A device disconnected from Ethernet port 1
19:37:31, 06 Apr. Wire Lan Port 1 down, Speed 10 Mbps

What has to be remembered the device work without issue at another location, possible with a different router model.

The event log I reviewed did not show any evidence of MAC spoofing as only two MAC address were noted.

192.168.1.115  28:16:a8:f4:b4:3d wired
192.168.1.117, 28:16:a8:f4:b4:3f wireless

If the disconnects continue the next step is to disconnect the network cable and try wireless

As an experiment I would suggest connecting the xbox via 1000Mbps switch connected to the Hub Two

I am concerned about information overload!

Edit I have found problems with BT Smart Hub 2 which match the issue reported here.

[#10]

Thank you all for responding...

I have disconnected wireless, leaving him wired via ethernet and he seems to be working for more than 5 minutes ATM! (Dont speak too soon!) I have looked at some of the links posted - wish i was the guy complaining of only get 200mbps! 😂😂

The openreach guy plugged his testing machine thing into the back of the xbox today to test the port and said the port had no issues.. ? he didnt tell me speeds etc but said it was working. I will look into a costs for a repair though! I will get the other xbox out this weekend, its the model before this one but worth a shot! The only thing on the xbox troubleshooting i have not tried is resetting the xbox to default settings but keeping games etc which i have tried to avoid but think i am left with no choice but to try now. I wouldnt know where to start with disabling the MAC address spoofing? is that in the hub manager or on the xbox settings? 

He was working fine on wifi yesterday, and since the open reach visit we are getting better wifi speeds so i will end up reverting back to that if it continues but i cant let this issue win! something so simple as plugging in a bloody cable to a device should work and its frustrating me that it doesnt more than anything else! should be plug and play!! 

When you say connect via 1000mbps switch - do you mean one of these things? 

https://www.amazon.co.uk/TP-Link-LS1005G-Wallmount-Ethernet-Splitter/dp/B07VWB347G/ref=asc_df_B07VWB...

if so - i tried that before and it changed his nat type to strict which i managed to overcome but then the same issue kept happening with the connection dropping out.

@Dan_the_Van 

Can you please post a linky to the BT Smart Hub 2 report ... I am sure that it will be of interest to @bobpullen 

Thanks.

@bobpullen is there anything which remote support can inspect here which is not available in the technical log?

As an approach to issue elimination, can you offer any input to the problem reported back in the earlier part of the thread where the attempt to use the Hub One failed related to UPnP settings? https://community.plus.net/t5/Broadband/LAN-Port-Disconnecting/m-p/1914644#M356078

[#12]

@Dan_the_Van spoke too soon! just booted him off!! So strange how it will work for so long and then just disconnect.. 

he had about 2 hours out of it earlier before dropping! (we have tears now as he was winning the game!!! 🙈)

@Sheppy127 

yes the switch is fine, I have a 8 port version.

Time to try wireless.

@Townman 

I'll have a search in the morning as now away from my pc 

[#14]

Iv reverted him back to wifi for this evening, will try the other xbox tomorrow and go from there!

This issue is consuming too much of my time, mainly because i wont give in and i now need a beer!!

Thank you all for being so helpful  

Hopefully @bobpullen may be able to assist more too, issue with ringing support is you dont speak to the same person twice and it can get very frustrating having to explain everything again despite having tickets open with the issue etc. 

[#15]

@bobpullen 

There is a pattern here which looks consistent, does it give us any clues...

• Wire Lan Port 2 up, Speed 100 Mbps
• A device connected to Ethernet port 2
• Wire Lan Port 2 down, Speed 10 Mbps
• A device disconnected from Ethernet port 2

This occurs 3 times followed by

• Wire Lan Port 2 up, Speed 10 Mbps
• A device connected to Ethernet port 2
• ... and then we get connected

This looks like attempting to negotiate 100mbps with a device which should do 1Gbps and after repeated failures settles on 10mbps ... until the next break.

What would you suggest to progress the investigation here please?

@Dan_the_Van 's suggestion of putting a 1Gbps switch between the Hub Two and the Xbox, would if that worked somewhat substantiate the possibility of a Hub Two - Xbox interaction!
