I always use advanced settings. Configuration steps are the same as innacomm cos they are almost the same since broadcom.
What i did: go to advanced setup, delete everything under WAN and ETH if possible, then under WAN create interface with vlan 500, priority 0 but name INTERNET (case sensitive and v impt be exact), choose pppoe and enter credentials + custom dns. Done.
Repeat same thing for hypptv, create interface vlan 600 name IPTV, choose Bridging, done.
Then go to advanced setup, interface grouping, assign lan port 4 to iptv interface.
Lastly, delete every entry under the QoS settings page, disable ipv6 everywhere, enable upnp (optional)
Once everything works and your wireless ssid + password + channel ok alr, pls DO NOT ever try to change the config again. Keep backup of the config file to be safe. This router firmware is the most shitty i have ever seen, worse than all of the tm router. This aztech is just a beefed up innacomm that support turbo and fast wireless lmao
Done with some of the settings, but still not working.
