Using GL-AR750 as router connect to nbn box from 100M ethernet, connect all computer from wifi. shows no internet connection. Can PPPoE, get IP address, Ping, nslookup and traceroute looks good but couldn’t open any web page from internet as well as using apps access internet. Take cable from GL-AR750, using pppoe dailer on computer, it works. so what can I do to fix this issue?
