Hi all, this seems like a basic question but I have had no joy from contacting TPG and I am tearing my hair out.   I have recently purchased the Deco XE75 mesh system, but setup fails every time.  I get through all until it tries to connect to the internet and it tells me it won't.  When I called TPG support, they said the system wasn't "compatible with my service" and sent me a link to devices that are.  The TP-Link Deco is listed in that link!  (Although not specifically the XE75.)   Support also said it's because the Deco doesn't have a dedicated WAN port on the device however, the TPG customer support page for the device (see link below) tells me to plug into the ethernet port 1 then the Gateway port on the NBN box, which is what I am doing.   https://support.tpg.com.au/how-set-tp-link-deco-nbn-   The only difference between the instructions in the above support page and what I am doing is that the installation fails before I can go into the "advanced" step (although I think the app is a newer version now as the screen shots look a bit different).   Can anybody please explain to me like I'm an idiot why my Deco XE75 is "incompatible with my service"?   Thank you, Katrina   ...
