Retrieving data is very slow with Windows 11. Using the very same PC with Windows 10 works fine (user says that it is the same driver). Wired access works fine. Performance against everything else is perfectly fine so far. On a speed test we get 300-400 Mb/s.
Using other Wi-FI cards seems to work fine.
We have tried most of the remedies suggested in various internet forums. Turning off Wi-Fi 6 changing settings, etc.
So far, it is impossible to see if jumbo frames is being used since the driver and the server network card might not allow access to the level where packets are transmittet. Hint : TCP Acks are invisible.
Any suggestions to what we can do do make the AX211 work for us?
Correction : AX411 changed to AX211.
