RT-AC68U: Firmware:380.68_4: IPTV Disconnects

[Arjen]

Hi, I've run into an issue while trying to replace the router provided by my ISP and provide all services through my own router. I would like to do this because the router provided does not support 5G wireless and the range of the 2,4 is poor.

Brief description of the issue
Intermitted connection with all channels. I have signal for 5 to 10 seconds. After losing the signal it can be recovered by changing channel, doing so immediately recovers the signal, but again only for 5 to 10 seconds. However, video on demand works without issues.

Notes

1. I cant use Movistar ISP profile, since it´s specifically for Spain. They use different routes and vlans. (Unless you know of a way to modify the profile)
2. Merlin firmware demonstrates the same issue across different versions. Therefore I also expect the issue to be a configurational issue, not a firmware issue.
3. Asus firmware doesn't work, as it doesn't allow for custom scripts. (and also the Movistar ISP profile is incorrect for Chile)
4. FYI: Static IP partially omitted in this post.
5. In Spain they have had success with this configuration (with their vlans and routes)
6. Reference: https://www.adslzone.net/postt404038.html

Any help would be greatly appreciated. Thanks,

Fixed. 3 changes:

2 additional static routes (services-start)

ip route add to 172.25.0.0/16 via $MOVISTAR_TV_GW
ip route add to 172.26.0.0/16 via $MOVISTAR_TV_GW

Added the following in dnsmasq.conf.add, not sure if this was really needed.

dhcp-vendorclass=ial,IAL
dhcp-option=ial,6,172.29.66.5
dhcp-option=ial,240,:::::239.0.2.10:22222:v6.0:239.0.2.30:222227

Instead of 3 subnets, I joined them in 172.0.0.0/8. Also added phyint disabled for ppp0 & vlan2 (internet)

quickleave
phyint vlan7 upstream ratelimit 0 threshold 1
altnet 172.0.0.0/8;
altnet 200.54.244.0/23;
phyint br0 downstream ratelimit 0 threshold 1
phyint ppp0 disabled
phyint vlan2 disabled

Everything seems to be working well now. Thanks to all for taking the time to read my post.
