Dear sir,
Good day.
If you're aiming to optimize performance, these settings are well-suited for modern deployments. However, ensure compatibility with legacy devices in your environment before deploying.

Best regards,
Lex

Hi Lex
Yes my objective setting is to improve performance speed local transfer for client to NAS via Wireless. Before optime rate-set i've only get speed below 3Mb/sec (file transfers). After optime by disabling low data rate better up to 10Mb/sec in radio 5Ghz. Can the mcs rate-set below still change and at what number exactly?

Dear sir，
Good day.

• Increase the number of spatial streams if the hardware supports it (e.g.,
  rate-set 11ac mcs-support 39
  for 4 spatial streams).
• Enable wider channels (e.g., 160 MHz for 802.11ax).
• Ensure the environment supports advanced features like MU-MIMO and OFDMA effectively.
  

Best regards,
Lex
