@ auron777 QOS and NAT boost not working together. You must disable NAT boost in order to use QOS...

I'm asking why QOS and IPTV cannot enable together. Not QOS and NAT boost. DLink router like DIR850L can enable QOS and IPTV/VLAN together. Heck even Archer C5 can enable IP QOS and IPTV together too. So why this Archer C7 v4 cannot?? And I expect previous Archer C7 v3 can enable QOS and IPTV together by looking at their interface..

finally v2 upgrade to v4? thanks

V4 hardvare also have serious problems with NAT boost. If PPPoE connection drops or restart, after reconnecting, the router becomes unstable and download speed drops under 50Kbps and some websites are unavailable. Everything comes to normal after a reboot and keeps until next PPPoE drop/restart. If hardware NAT is disabled the problem will not occur when PPPoE drops/restart, but download speed is limited to 300mbps. And TP-LINK not hurry to resolve the problem...
