I don't know if the BT router gives priority to TV traffic or not.
I don't use the BT TV that much so can't comment.
The stock firmware of the access point works fine, so I think it's just the OpenWRT firmware. I'm almost certain it's related to software packet steering whereas the stock firmware uses hardware for this. Hopefully support will come soon.
sorry for the thread revivalā¦..
New issue surfaced tonight. I am getting severe issues with all channels. heavy pixelation etc and stuttering.
I have changed nothing with the setup/config. Has anyone else had issues? Possibly due to a EE box update etc. I tested the original BT hub and worked fine so definitely related to my Flint 2 router.
EDIT: Currently seems fine. Possibly intermittent. Will update if it happens again.
Iām trying to run IPTV behind OpenWrt using igmpproxy. The internet connection works fine and some IPTV channels load correctly, which suggests multicast is partially working. However, many other channels do not work at all or fail to stream, even though they work perfectly on my ASUS RT-AX53U using the same ISP connection and identical network setup.
On the ASUS router, IPTV works when I enable the built-in IPTV settings with the following options turned on: Use DHCP routes (RFC3442 & Microsoft), Enable multicast routing, Enable IGMP Snooping, Enable Fast Leave, and keep UDP Proxy (Udpxy) disabled (set to 0). With these settings, all channels work normally and the IPTV is stable.
here are openwrt configs.
