Hi,

I did some further researches, but still no progress. 

I found an TL-SG105e v5 switch and connected it with one of the LAN Ports of my ER7206 Router. After that I connected the Telekom Media Receivers to the little 5 port switch. But the result was the same. After a few seconds, the screen freezes. 

Eventually I could set up the little switch between the Speedport "Modem" and the ER7206 Router, but then I would lost the possibility to reach the Media Receivers from my mobile phone, that's connected over the AP/24port Switch, right?

Best regards,

Lars

Hi, 

here are some screenshots of my Omada configuration. 

The connection to the Media Receiver is now back on Port 5 of the SG2428P switch.

Router settings:

VLAN for the media receiver: 

The profile (nothing tagged/unteagged... is that correct?):

The mapping to the Port of the Switch: 

And I just saw, that there is a Switch option to enable VLANs... I didn't change anything there, tv is disabled?

IGMP snooping is disabled for the other VLAN interfaces, except LAN. Can't do changes there...

I would be so happy, if you have an idea, what I can try as next steps. The internet connection, LAN, Wifi, telephone, everything runs perfect but without TV I get no approval from my wife :-)

Best regards,

Lars

Try to enable igmp proxy on router

@shberge thanks for the reply. I tried it, with IGMP proxy enabled, but it didn't work. On the screenshot you see my last attemp with disable the proxy. 

@Orandus 

I'm pretty sure you did everything right, but you probably need to have IGMP Proxy on the router.
I do not have any IPTV self so I can not help you with the testing either, to me it sounds like there is a bug in the firewall.
It has not been completely without problems with ER7206 and ER605, I have probably never in my 25 years in IT had so many problems with a router before.
but tp-link is working hard to fix the issues so I think it will be fine in the end.
You should contact tp-link support if you have not done so. they may be able to help you. you can meet them this e-mail adress support.smb@tp-link.com
it's nice if you post the solution here if you find any solution.

@shberge yes, I'll try the support now. My hope was a fast answer out of the community with: "Hey, set this to that and it will run", but it seems to be not so easy :-) I'll come back, when I have a solution. Have a nice weekend!

Hi,

today I got answer from support: It's a known issue between ER7206 and the Deutsche Telekom Media Receivers. They are working on a fix and will deliver it in the near future. 

I asked, what "near future" means and if there is no work around, but they didn't answer the first question and answered that there is no work around, but a german R&D team is working on it... Was not the solution I expected.

I'm wondering, if I should enable the Router functions of the Telekom Speedport again and put the ER7206 as second Router (double NAT) behind it. Then I could connect the "TV" ports directly with the Telekom Router and the rest of the network with the ER7206. Is a dirty solution and I'm not sure if it works... And I have no connection from my mobile phone to the Media Receivers.

Best regards;

The support asked for a TeamViewer debugging session and sent a debug patch to me. It seems, that there will be some progress on that topic. Will come back after the session this week.

@Orandus Hi,

Is there something new here, because I also have the same problems, but I use the ER605 as a router. IGMP proxy is activated with V3 and IGMP snooping in the IPTV VLAN as well, but after about 10 seconds I get a jerky picture and then a freeze frame with an error message. According to the system check, everything should be OK. I also use the 401 and 201.
