Sky max hub - no internet - green blinking light

[Hopeful1]

You need to describe what colour the LED is showing and whether it is a solid light or flashing

If it is flashing, is it a slow blink or a fast strobe.

And if you can, open a web browser to the IP of the browser and post a screenshot of the firmware version

@Owais1 , @Christ_protein , @mk7249, @eching 

Please post the Model number (should be visible on the outside of the modem) and post the firmware it is running (you will find this when opening an 'admin' session in a web browser that is pointed to the LAN IP of your router).

I want to check something.

Thanks in advance

When you say this"I have no idea what the engineer meant but the DSLAM in the companion digital cabinet generate the VDSL signals which carry digital data from the cabinet to your home by using a series of high frequency carriers.  The  modem stage in the router converts those back into a digital signal and passes those to the router stage. Where there is still a POTS analogue voice service that is split in the main cabinet and goes back to the exchange over copper cables. etc"

It really matters not, I am telling you that if I plug in a SR102, I get Sky broadband connection. When the Openreach engineer tests the connection with his test modem, through my socket and down to the Sky backbone, he gets a connection.  Please, take it from me, the infrastructure is there and it's working. 

here is a picture which will show you the engineer's tester,  I have partially blurred out the Sky IP and my unique line number.

I hope this will help you let go of the equipment side of things and instead focus on the software side of things:

You are mentioning MAP-T and NAT.  AFAIK NAT is applicable to my home network.  It is the router's way of funneling several consumer devices, to one single publically visible IP address, without exposing the consumer devices.  Essentially, my Sky IP176.248.x.x is translated to 192.168.x.x (and a port)  You are now adding MAP-T to the mix, where you seem to indicate that the translation and mapping goes a step further, by including the DHCP side of things.  Interesting

The problem is simpler than that, after a firmware update on the white SR213, the modem is no longer able to obtain a public IP address.

Do you have a white Brick?  If so, can you a photo showing the model number and a screenshot showing the firmware?  Can you also go to the maintenance page and show your IPv4 address (albeit blurred).  That would really help me understand a few things.  (And just to make sure you understand what I am saying:  The original firmware allowed for this Map-T to work, but after an update, no IP address can be obtained.  That to me means we are dealing with a firmware issue, not a hardware/architecture issue.

You say: "Given there are many hundreds of thousands if not millions of each model of hub the fleet can be running more than one release this is entirely normal. Sky do not give details of what each release includes.".  Show me.  Show me numbers of how many White Hubs are out there, as s relative, as a proportion and how many of these are not in session, or have not been for 48 hours.  Otherwise, I have a stat for you: these are brand new, being sent out for new customers, and there aint 6 million new customers!

You say: "One of the perks of being a forum superuser is we have access to other Sky staff including in this case a briefing by the chief network architect".  please could you ask your network architect, to explain in what scenario the MAP-T would not be negotiated and "the system" would fall back on traditional IPv4.  I'd love to see if this is possible with a white SR213.  For sure, the SR102, simply does not support the MAP-T protocol and presto, I have a solid connection.

You say:"This is massively off topic for this thread the green flashing led on a SR213 cannot be caused by IP addressing issues it is a failure to negotiate a connection.."

Please can you point to a document which details what conditions need to be met, for the green light to slowly pulse?  Can you also hypothesise why there would be a failure to negotiate a connection?

Please, upload the photos as requested above, I think it would help in us getting a common understanding of my issue and your knowledge

Thanks

@Hopeful1 I give up.

@Chrisee 

before you give up, do you think you could give the information I need to prove or disprove my theory?

Your signature says you have a Sky SR213(white Wifi Max hub), could you dump info on your firmware?
