Hi There,
Been trying to setup my VMG3925-B10B router up for BT and youview.
Currently, I have setup my router, it has Internet Access and the boxes are connected to them. The YouView boxes have internet access, an IP Address, and can even use the apps, such as NetFlix, BT TV etc, with no issues.
Unfortunately, however, my internet channels are not working.
I have enabled IGMP and MultiCast, and they are all present and set, but it still wont pick up internet TV. I include a copy of my config file from the router, if its any help, but I cant see why TV wont work, the YouMax states there is internet connection, the apps work...
Any Advice? or is this the wrong area to ask in?
I Include screenshots of each of the settings pages, in order to try and see if anyone can spot something I havent?
I have uploaded it to my google drive as I cannot find a local upload option for a zip file, when I have 52 images...

Thanks

Sorry, what do you mean by ‘internet channels’? :-)
You are in the right place and I am sure someone will be able to help you out.
And welcome, if I haven't said it already!
If some services work and others don't it could be because they use different protocols. One live (approx) TV service may well be using IP multicast. Or it could be using who knows what, there was a recent thread where I myself asked about how for example BT’s TV services work.
You might have a ‘VLAN’ setting somewhere in your router setup/config settings relating to the DSL connection, and it might be an idea to dig around to see if you can see that and check that it is as the ISP says it should be. It may not be there, so don't think you are going mad if you can't find it.

I believe IGMP is rather fussy and that for the VLAN tagged as 101 the 802.1p parameter needs to be set as 1.

Youview internet channels (provided by BT TV, Talktalk TV, Plusnet TV) use Multicast, not the more commonmy used Unicast.
On Demand works but the internet channels just refuse to play.
Routers require IGMP v3 and Multicast support. It can be awkward setting up some non ISP routers.
-
Am I right to question whether MLD & default gateway is missing a tick here?
Also, disable UPnP and NAT-ALG.

Google says yes all over :baby:

Hi guys and thanks for your replies:
@Weaver: I refer to the Internet Broadcasted "Extra Channels" - things like Discovery, Nat Geo, Kids Channels etc (none freeview / aerial delivered). All the IPTV channels are failing. I configured the VLAN to 101 as required and defined in BT threads. That said, I can access the likes of the Netflix, BT On Demand Video streaming applications installed on the box. I have had a look at those threads, and started a seperate thread in the BT Youview chat, with the same details and screenshots. The only thing I can no longer find on the interface, though appears in a config file - appears to be removed from the firmware - "Enable Concurrant WAN", so I tried creating a new connection bridging the VDSSL and ETHWAN.
Also, thanks for the welcome.
@burakkucat, I will try to put the 802.1p to 1 and see if it makes any difference. Is this in a particular location?
@spring, I wasnt sure as I dont believe BT use IPV6 on my router, but also I use only IPV4 on mine. As for the query of 802.1p I have already tried this, and it didnt work, but I did change other settings - as you say, google says it all over - so I tried it and it wasnt successful.
Thanks for your ongoing thoughts!

Followed that one as well @tubaman, thanks for your suggestion though.

Sorry if I'm not following along, but have you changed this setting or not? You ask where to put it, then say you have already changed it. Its under Network Settings -> Broadband -> VLAN. I dont know for sure but I would assume it requires a resync to take effect.

So it is all about getting multicast going, it seems. An ISP with clue might come in useful at this point but some will just tell you to go away if you are not using their standard or even mandatory modem-router.
A bit of a side issue:
If you get IPv6 from your ISP now then I would absolutely definitely get it set up and use it in preference as you will have an easier NAT-free life. You might need some magic runes from your ISP as I don’t know how they choose to deliver info such as your IPv6 prefix - ie tell your router over the network what address block has been allocated to you - or whether it is a static IPv6 prefix (hopefully!) and you can just enter the right value into your router, configuring the address range manually so no concerns about methods of delivering the info as you already had it. Ditto with info about DNS servers delivered over who knows what mechanism, as there are several possibilities. I have used IPv6 for a long time and I just configured all the right numbers into my router by hand.
Some of the big ISPs are finally waking up and beginning to deliver IPv6 to their users.
-
Thanks Folks,
@Johnson, I haven't yet, at work and need to test it as soon as I can.
@Weaver - Agreed, I tried to ask BT, but they are very much of the "pay for the Home Hub 6" attitude.
-
BT users’ forums might be useful too if you get stuck, but there are definitely people here who really really know this stuff. I cannot help because I know nothing about BT, their multicast TV system or this model of modem-router, so I am as much use as a chocolate teapot.
[My ISP, Andrews and Arnold (aa.net.uk), doesn't deliver multicast over the public internet (although not the same thing). AA has thought about it and asked customers about it but no-one is asking for it.
I use Netflix, Youtube and Amazon video (plus very occasionally Apple’s whatever it’s called store) for TV programs and movie downloads, on my big iPad, and I don't ever use a telly. My dear wife has a big telly and a Freesat box and this provides us with a huge amount of extra bandwidth because BBC / ITV / C4 and so on are not eating my pay-for-what-you use DSL internet connection. But I am in bed all day every day.]

I've noticed you are using Wireless rather than Wired on the group interface named YouView, if you do then by all means necessary, disable Enhanced Multicast Forwarding in the wireless page, and after doing so shut down all network devices and then back on.
[Post Ive written prior to realizing Wireless might be used to connect the YouView and recalled Enhanced Multicast Forwarding is enabled by default on a VMG1312-B10A]
I was just going with the flow on the MLD tick according to the screenshots :)
It can be many things though that's true, hope the sneaky cause is found.
The sure way would be trial and error on this and other devices, and may be off-putting for some xD
If the PPP connects without dual stack then I would backup the config, then try configuring all the router for IPv4
Edit: You might have to use an older firmware for Con-current WAN.
Odd fact: Disabling IGMP sometimes make IPTV work.
Is it possible to create a bridge? Someone said it made it work, I'm wary that I'm imagining impossible things :)
-
Thanks for your reply @Spring, I cant find the enhanced multicast option, but the youview boxes are connected wired, not wireless. Which page were you referencing? I need to correct this!
-
Also attached the group interface settings that you posted, in case someone spots a misconfiguration.
In addition I'm starting to think it may be firmware/telnet-command-required/other devices -related. What other devices can you configure?
There have been some seemingly mythical anecdotes suggesting resetting to factory default and starting again a few times had eventually worked. Doubt it though.
Is ROM-D cleared?
Edit: Is the TV WAN interface MLD/default gateway enabled and set to Bridge mode? The MTU I assume is max 1498 and not 1500 ?
Edit2: You should be using the Supervisor account for all things on the router & I hope ROM-D was cleared. Re-configuring to use IPv4-only could help. I'll look at the telnet manual however because this is puzzling.
-
Don't think it has been mentioned but I have seen a couple of devices that only use multicast on one lan port (1 or 4 normally) so may be worth checking.
Edit: Doesn't appear to be the case from the user manual.
-
You're right, it does make sense to use LAN1/LAN2 for the bridge interface and connect the Youview to LAN1. Whilst the default group is on LAN3/LAN4, and the device that needs LAN access to the VMG3925 which has more multicast needs, connected to LAN4.
(https://kitz.co.uk/routers/images/VMG8324_rear_bridge.png)
If this wouldn't be solved a firmware downgrade [to AAVF.10 (http://ftp://ftp.zyxel.fr/ftp_download/VMG3925-B10B/firmware/VMG3925-B10B_5.13(AAVF.10)C0.zip)], reconfiguration & con-current wan setup [present in v10] would be worth a shot.
Edit: Con-current wan is more than worth a shot. Very high chance to be the culprit.
Edit2: Does someone by chance have the 3925 CLI manual? Not important but useful for OP.
-
Sorry folks, havent had a chance to look at this, hoping to get back around to it soon!
- ROM D is not cleared, as I have no idea how to do this, or no knowledge it was to be done....
- TV WAN MLD I believe is enabled, will double check though
- MTU1 I believe is 1498 as this I believe was its default value
- The admin account had its password changed and is the only account I am using at this time.
- I have two Youview boxes which I am trying to connect to my port. I currently have one connected on port 1 and one connected on port 4
-Con-current Wan, though located via downloading config to file (and searching the file) appears to be a redacted option on the interface in the new version 13, so I may well need to downgrade, but unfortunately I can not find any version 10 instance anywhere :(
-
You need to find the supervisor password to clear ROM-D
