Yesterday I received my new BT TV box to which I have subscribed to the full package, on installation I hit a major problem that I wonder if anybody could assist me with.
I have a BT Hub sited in my Dining Room (don't ask it's where the BT Engineer decided to instal the incoming land line socket) this is then connected to a BT Flex 1000 unit via the Ethernet cable and the second Flex 1000 is connected into a socket behind the TV.
Connected into the Flex 1000 behind the TV into Ethernet Port 2 is my NOWTV box (which I am keeping so I can watch the F1 via Sky Sports) this set up has worked without any issues or problems for at least one year and with great picture quality. Until last night.
So I connect the BT TV box up following the instructions on the box, plug the Ethernet cable into Ethernet Port 1 on the Flex 1000 and turn on the system. Great the BT TV box says its updating etc so whilst its doing this I decide to watch a program on my NOWTV box except now the picture quality is rubbish and then it just disconnects and dispite me trying to reconnect it, it fails to connect.
In the meantime the BT TV box has done its upgrade and is now in setup mode, great all the Freeview channels are there but NO premium channels - the box is not connected to the internet. So I try again with the same results, no connection on both the BT TV box and NOWTV box. Lights on the Flex 1000 are blue for Ethernet and red for data.
I phone BT and one hour later and many presses of the link button and disconnections the NOWTV box work again but not the BT TV box.
This morning when I take a look at the Flex 1000 units the Ethernet connection is blue and the data is red.
the chap I spoke with last night did a connection test and all was well and I did a speed test on my phone app and it was showing a 50Mbps download speed.
Solved! Go to Solution.
Welcome to this user forum.
I suspect it due to the way that the BT Flex 1000 is dealing with the multicast stream that is needed for the extra BT YouView channels. They may not be able to handle this.
The only ones recommended fror BT YouView, are the BT Mini Connectors.
Thanks for taking the time to reply, looking at the mini connectors what is the difference between them and the Flex 1000 - they seem the same plus when I ordered the BT Tv package last week I said I had Flex 1000's and I was told that would be fine.
Its unlikely the order team would know the difference, as its not a speed issue, but an issue with multicast.
If the BT YouView subscription channels do not work, even with the NowTV box disconnected, then that proves that the Flex1000 units are not compatible.
If Data is RED that indicates low transfer speed. Try a factory reset to start with.
Also these where produced in 2015 or earlier which might have been before BT used multicast transmission.
The problem that a lot of devices have with multicast is that it can totally flood the network unless switches, PLAs etc can handle IGMP Snooping which basically means knowing which device requested the transmission & direct it to that device only.
I'd suggest probably the PLAs that @Keith_Beddoe has mentioned and then at the receiving end a 5-port TP-Link SG105 switch. I suggest that switch because both my son & I use them for this very reason and they're plug&play and not expensive.
I think its possible that the mini connectors, which have two Ethernet ports, may have IGMP snooping enabled. That would allow another device to connect to the second Ethernet port, without interference with the YouView box on the other port.
So an additional switch may not be needed.
As the mini connectors are heavily discounted at £20, via the TV team, I would try those first, before buying anything else.
Based on your comments I have just spoken with a BT (tech) guy in Belfast who said that the Flex 1000 and the Mini Connectors do the same thing, it is probably a configuration that is wrong with the Flex 1000 and suggested I contact the BT specialists - which I will do.
With regard to the red data light and low transfer speed, I think this is a red herring as the speed with all my other items is normal, with the exception of the NOWTV box running slow last night when the BT TV box was pluged in.
and suggested I contact the BT specialists - which I will do.
That will cost you money, as their service is not free, its £10 a month.
I doubt very much that they will be able to help.
You would be better off with the £20 mini connector offer.
Right so when I got home last night I did a little more experimentation and if I run a long Ethernet cable to my Home Hub and set up the BT TV box it connects to the internet and picture quality is fine.
The issue as I see it is with the Flex 1000 extenders the RED data light is lit up which as far as I'm aware is low download speed.
However when I do a speed test using an app on my phone I have a fast download speed, so what has changed?
My thoughts are this, when BT sold me the BT TV package as a sweetner they also upgraded my Broadband package to the fastest speed available in my area which went live Tuesday, and it has been since then that I am having the problems.
Prior to Tuesday my Flex 1000 extenders were working fine with a solid Blue light lit on both data lights, now since Tuesday I have solid Red lights lit. This is irrespective of Ethernet cables plugged in or not.
Any thoughts please?
