Entire LAN goes down when playing Microsoft Flight Simulator
As the title says my entire LAN goes down as soon as I start a flight in Microsoft Flight Simulator. I've been away from the sim for a while and recently picked it up again and I haven't had this issue before. If I bypass the router and connect my computer directly to the fiber converter the problem goes away, but somehow the X60 doesn't seem to cope with MSFS at all. My computer is connected with cable to the main unit and I have a 250/250 fiber that I have no other issues with at all. I've turned off all network protection features in the router and have the QoS set to 1000/1000Mbit with all service types to the right, I've been fidling with this but nothing helps. And I have restarted the router of course.
Anyone else have this issue? Any solutions?
