[paullongy326]

hi all i hope this helps people has i was on windows 11  and did factory reset on superhub   i restarted  and found slow speeds terrible slow speeds 

i also had a windows up date at same time  i found something with a bug on win 11 that mesed ethernet auto tune up 

here are 2 commands in elevated (admin)command prompt to try 

first run this netsh interface tcp show global

if its disbaled or anything but normal run this command 

netsh int tcp set global autotuninglevel=normal

i tried all sorts until i came across this i hope it helps everyone

Thanks for this - it might well come in handy in future.

One small point: you don't need to run as admin to query the interface so you can execute the first netsh command at a normal (unelevated) cmd/powershell prompt which might be safer for folks that are just trying to diagnose connectivity problems.

Cheers.
