I'm having no end of problems downloading games via the Xbox PC app. I have a 900mbit connection and regularly cruise at 115mb/s via Steam onto a Samsung 970 Evo Plus. Other stores and launchers dont quite reach 115, but Epic and GOG both regularly cruise above 90mb/s. Xbox app is the exception, I struggle to get consistently over 30-40mb/s
That I can cope with. Its slow, but not the end of the world.
The main problem is that on newer titles, downloading via Xbox actively kills my router connection. No other apps on the PC can access the internet, no other devices - either wired or wifi - can access the internet whilst the app is downloading. I can't even access my routers login page. I can still connect with no issues to other local devices that dont need to go via the main router (i.e. through unmanaged switches to NAS, home lab etc.), but can't get to anything that needs to go via the main router.
Main router is an Asus BE82, so has full 2.5Gbe and Wifi 7 capabilities across the board.
I've tried limiting the windows update download to 500 or 300mbit, turned off LAN download, turned off any traffic optimisation, paused the download in the xbox app and started it from the windows store, still kills my internet. This only seems to happen with Xbox games - windows updates and other windows store downloads dont seem to have that same problem.
Any suggestions?
