https://community.extremenetworks.com/t5/extremewireless-identifi/what-does-the-f-mean-in-the-protocol-column-on-the-active-client/m-p/44556#M3760 I have two C5210 controllers in HA running 09.21.16.0013 code. Running 1300+ mix of 3610, 3715 &amp; 3825 APs I just noticed that the Active Client reports are showing some users with "2.4n|F" and some with "5.0n|F" in the protocol column. I don't recall ever seeing the "|F". Does anyone know what this means?<BR /> <BR /> <P class="fancybox-image"><span class="lia-inline-image-display-wrapper" image-alt="68812faaaab143579dbd004bd3eec4ba_RackMultipart20170410-38863-1t3agfb-Capture_inline.png"><img src="https://community.extremenetworks.com/t5/image/serverpage/image-id/573iE0DD5D34218BABF4/image-size/large?v=v2&amp;px=999" role="button" title="68812faaaab143579dbd004bd3eec4ba_RackMultipart20170410-38863-1t3agfb-Capture_inline.png" alt="68812faaaab143579dbd004bd3eec4ba_RackMultipart20170410-38863-1t3agfb-Capture_inline.png" /></span></P><BR /> <BR /> Thanks,<BR /> -Rich Pacheco Tue, 11 Apr 2017 01:13:00 GMT Rich_Pacheco 2017-04-11T01:13:00Z https://community.extremenetworks.com/t5/extremewireless-identifi/what-does-the-f-mean-in-the-protocol-column-on-the-active-client/m-p/44556#M3760 I have two C5210 controllers in HA running 09.21.16.0013 code.
