@richpriest They are TP-LINK switches. I've not tried directly from downstairs M5 to my pc. As that would mean nothing else has internet. Think my family would kill me 😂 I'll try it Saturday when...

I'll preface this by saying, I don't expect a resolution, but would love one. This issue only seems to effect 1 game, on my PC. PS5, PS4, other pc games, are all fine. Was all fine for maybe 9 months...
