This SSID is a semi open net that functions as a guest net, so I have all kinds of clients connecting to it, with no issues.<BR />The customer have now bought some smartscreens from I3 technologies model is E-One86.<BR />These screens are a nighmare, some will connect and work fine, some will connect and just be thrown off again within 5 min, and some will not connect at all.<BR />I have alot of these faults from them.<BR />"EAPOL Failure: Previous Auth invalid"<BR />When I look at the fault, it looks like the AP sends Frame-1 in the 4-Way Handshake a few times without any response, so in the end the AP sends a Deauth packet.</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="tommy_kreutzfe1_0-1708423737290.png" style="width: 400px;"><img src="https://community.ruckuswireless.com/t5/image/serverpage/image-id/10819i3DB98B807719B787/image-size/medium/is-moderation-mode/true?v=v2&amp;px=400" role="button" title="tommy_kreutzfe1_0-1708423737290.png" alt="tommy_kreutzfe1_0-1708423737290.png" /></span></P><P>This is not something I have seen before, and must admit I'm abit lost here.</P><P>Anybody have any&nbsp;experience with these screens or this fault ??</P> Tue, 20 Feb 2024 10:15:43 GMT https://community.ruckuswireless.com/t5/Wireless-Questions-and-Best/Previous-Auth-invalid/m-p/75970#M2300 tommy_kreutzfe1 2024-02-20T10:15:43Z https://community.ruckuswireless.com/t5/Wireless-Questions-and-Best/Previous-Auth-invalid/m-p/94613#M2675 <P>Curious, Tommy, did you get to know what the cause for this info was?
