Hello!
Recently I've upgraded from "VDSL2" to "VDSL2 MAX", which came with it's own modem and router. (This is in Australia if it makes a difference).
Intermittently the connection to the internet will drop out. I've reported the issue to the ISP, who has sent technicians out 5 times. Both the router and modem have been replaced. They've tested the line and found nothing wrong. I have troubleshot all of the devices on my end and confirmed it's not something happening on my end.
But since it's been 5 weeks of barely usable internet I feel like I need to do all the troubleshooting I can to see if I can find any hints to give to the ISP.
The thing that has me very confused is if I stream a game to multiple friends using Steam remote play together over the internet (https://store.steampowered.com/remoteplay#together) the connection will survive the rest of my internet dropping out for about a minute.
So I'll be on Discord, talking to my mates. Suddenly Discord drops out, I can't load any web pages. But somehow my PC can still stream the game, I can see my friends reacting to things that are happening in the game.
My first thought was that DNS is unavailable. But even after updating my DNS to Google DNS on both my PC and the router the issue is still happening. If the line was unstable I figure streaming a full game to friends would break first?
Does anyone know of what could be causing it?
