RT-AC56U Firmware 3.0.0.4.380.7743 issue with IPTV.

[follower]

ASUS RT-AC56U Firmware version 3.0.0.4.380.7743 issue.

Model: AC56U
Firmware: 3.0.0.4.380.7743
After update: I cleared NVRAM.
Issue: Waiting for the signal for random channels shortly. There was no issue with previous version 3.0.0.4.380.7378. I tested this issue with two AC56U. But the result was same.

What's wrong with this firmware?
Does anybody have this issue?

I just installed this version on my AC56R and so far I haven't had any problems though to be honest, I'm not familiar with IPTV. WiFi works just as it did before as does WAN/LAN.
