The AP will not advertise certain MCS rates so the legacy devices will not be able to connect. Although you need to be careful with this setting - the RF should be very clean and the device should be in good proximity to the AP to make it work stable.

In the n-strict mode a frame header is used which older clients (= not 11n) can not understand. Therefore these clients see no wireless traffic but noise in the air.<BR /> <BR /> Because of these clients can't read the preamble they do not know how long it takes to transmit the frame and simultaneous transmissions can happen.<BR /> <BR /> Fri, 23 Feb 2018 05:42:00 GMT https://community.extremenetworks.com/t5/extremewireless-identifi/what-does-quot-n-strict-click-to-enable-the-802-11a-mode-of/m-p/30190#M408 StephanH 2018-02-23T05:42:00Z
