Yesterday a Vodafone technician came in and installed the new FibreX modem and installed the Vodafone router, but we have a Asus Ac3200 router for our websites which we installed in. He told me that to get it connected to the internet via the Asus router I needed to set vlan tagging on. The Vodafone router he installed worked fine straight away but when the asus router installed we got internet but very slow, and now it has fully dropped out and not coming back. Doing some research the Asus router has a setting that is like Vlantagging apparently IPTV in the router settings.
How do I configure this? i have set it to manual settings
