    Running a GT-AX11000 with a Draytek Vigor 130 on a BT 80/20 FTTC connection.

    Have solved the dreaded IP6023 issue with some tweaking of the Draytek settings.

    Now have a problem with the 4K stream flooding the router.

    The traffic analyser shows outgoing wired LAN traffic of approx 8000KB/s. Oddly the incoming WAN traffic is nowhere near this level, it’s more like 200KB/s. So something is not right.

    Any combination of AI Protection. QOS and Denial Of Service enabled/disabled does not improve anything. Strangely with AI Protection disabled CPU usage goes up.

    Have sent feedback to Asus.

    Any suggestions or advice?

    Thanks

    Q. Nice Router, did the 4K stream flooding the router happen prior to your tweaking on the DrayTek Router?

    Also, is DrayTek in full bridge Mode or PPPoE Passthrough?

    Prior to tweaking BT IPTV stream wasn’t working at all.

    Changing the Draytek to bridge mode is what got the IPTV working.

    Had this problem on a DSL-AC68U but that was due to the CPU maxing out while stupidly trying to provide AI Protection on the IPTV stream. With AI Protection off the 68 could cope admirably.

    I’m not convinced that AI Protection is working correctly. The way it is switched on and off is really odd. You can turn off AI Protection at the main toggle but it still appears to be running (according the the Router Risk Assessment Scan) if Malicious Sites Blocking, Two -Way IPS or Infected Device Prevention and Blocking are toggled on. AI Protection also does not appear to actually do anything when switched on, nothing showing in the logs.

    CPU is not maxing out but I’m not sure I trust what it is showing.

    Sounds like you have set up the DrayTeK as I would have, are yo connected via Wifi or wired and if not already,  ensure IGMP Snooping (proxy) is enabled  and see if this helps (LAN > IPTV)?

    AiProtection for DSL-AC88U, does seem to show same characteristics as your GT-AX11000, On even when it should be Off, and way to much packet inspection from/between LAN based appliances/devices.

    If issues are via wifi, under Wireless > Professional, there should be option to Enable IGMP Snooping etc. or at least there is this option on my RT-AC86U.

     

    If pos, turn off AiP  and reboot router and only enable once 4K streaming / flooding is working etc. ;-)

    4K streaming via wired LAN and Powerline adapters.

    Enable multicast routing (IGMP Proxy) is enabled for LAN

    Will try turning off AIP completely and rebooting to see if that makes a difference.

    Thanks :-)

    I assume you are on Firmware Version 3.0.0.4.384.5252 ?

    They key with AiP, is if it is On or Off, then Memory usage is higher with AiP On than Off (Linux Stuff)

    I assume nothing else has changed since you removed the old DSL-AC68U and replaced it with the GT-AX11000 etc? and I assume it was 4K running prior?

    Yes on 5252.

    Nothing else has changed.

    Powerline adaptors are TP Link 1200, they work fine.

    4K was working fine if AiProtect was turned off on 68.

    Interesting, hopefully disabling AiP on your GT-Ax11000 and a reboot will help identify the possible issue?

    If you do manage a reboot  and 4K works, let me know so I can have a chat with ASUS regarding AiP and DSL-AC68U / GT-AX11000.

    OK so fully disabled AiP and rebooted. Sadly no difference.

    Tried just about every combination of settings I could think of, still no difference.

    Find it really odd that the Traffic Analyser doesn’t show the incoming traffic but the wired LAN shows the outgoing traffic.

    If you can get Asus to shed some light on this I will be very grateful.

    This is a very new router so I guess it’s entirely possible that it’s one of a number of bugs that will be ironed out in the coming months.

    Yes, that’s my thought also, but will ask ASUS for clarity.

    I assume you have tried a different port on the router and also tried a wire between router and 4k device, if pos, just for testing? but do agree likelihood it is the router at fault, but that’s the sort of response ASUS would give, so planning ahead ;-)

    Not sure I have a long enough cable but will have a dig around and see if I’ve got anything suitable lying around.

    If there is anything else that Asus need from me please let me know.

    Have solved the issue after a lot of work and swapping of kit and cables.

    An extremely frustrating process full of false hope as the 4K picture settles then degrades again.

    Tried every setting under the sun on the router.

    Jumped technology with the Powerline setup from 1200Mbps AV2 to 2400Mbps G.hn.

    Tried various new Cat 6 and 7 cables to rule out local interference.

    Double and triple checked the Draytek settings although tbh there was nothing to change once in bridge mode. Yes it was running latest BT firmware.

    Then as a last gasp I swapped out the Draytek for a BT HG612 and hey presto, rock solid picture.

    Looking at the traffic monitor somehow the multicast traffic was doubling and also spiking even higher when using the Draytek.

    Thanks @Six for your time and efforts, as we chatted offline and for others reading this thread, looks like DrayTeK 130 even with BT (latest) approved firmware, is causing issues with IPTV streaming, after @Six switched out DrayTeK modem (bridged) and swapped in BT HG612 modem (Stock BT Firmware) streaming (4K) streaming worked for IPTV as expected.

    My Note: DrayTeK 130 Modem in UK may have BT IPTV (4K UHD)  streaming issues ?

    Are you running 384 firmware for DT 130 and check your pass through mode on Internet Access>MP0A/Static or Dynamic IP> check at bottom Bridge Mode Box is Ticked.

    In my router AC86U under LAN>IPTV> Microsoft and Enable multicast routing (IGMP Proxy) Enabled.  No other setting used.  4k streaming IPTV Netflix and Prime Video and BT Sports all work fine.  (I too had to reuse my old BT OR modem to check which worked.) is you TV Smart and have WiFi to setup… and not use the wifi plugins… also my dratek 130 is on my router for stats… via its own web browser.  I have used dsl 68u and dsl 88u, the latter would not work IPTV unless i changed the QOPS and set upload to 18mb/s to get a picture but then WiFi on both channels would not work… also echo alexa would only work on channel 36, but now they find their own channels.. weird right… really like the 68u and the 86u is so much better.

    Hi Mharv

    The Draytek 130 had the latest BT firmware and was correctly set up in Bridge Mode.

    IPTV settings were also correct (note that GT-AX11000 does not have an option for IGMP Snooping on wired LAN).

    I’ve a long history with Asus routers, most of the suggested settings you will see posted on forums today come the results that I and a few others arrived at after some experimentation years ago.

    The DSL-AC68U had issues with handling BT 4K if any of it’s extra features were switched on (Ai Protection etc.) The CPU would get overloaded resulting in the WiFi slowing down to a crawl, particularly on 5GHz. Switching everything apart from the Firewall and DDoS Protection off helped.

    In this case the CPU is much more capable, the CPU is not maxing out and the WiFi is not grinding to a halt. What appeared to be happening was that the Multicast transmission was swamping the BT IPTV box, leading to very bad breakup of picture and sound. That Multicast traffic appeared to be doubled when using the Draytek (according to the Traffic Monitor on the router). Using the HG612 the traffic appears to be halved and the problem goes away.

    Note this only causes an issue with the BT Sport 4K UHD channel 433, all the other IPTV channels (the HD ones) will work without issues with the Draytek in Bridge Mode.

    You are right that this is all very weird.
