WPA2_PSK-TKIP limits bandwidth to 54Mb/s

1 SSID configured with WPA2_PSK-TKIP limits the client bandwidth to 54Mb/s as PHY Rx rate. And this is due because TKIP is an old encryption method...

No way to have WPA2_PSK_AES_TKIP or equivalent to ensure on the same SSID the TKIP compatibility for legacy at 54 and for n or ac to have more than 54Mb/s bandwidth ?

The limit for TKIP was a WiFI Alliance requirement for about a year. The requirement was removed several years ago.
