EAPOL Failure: Unspecified

Question

We are having random periods where users connect to the WiFi but do not get an IP address from the DHCP server.  They show connected with no Internet, but they have a local IP address. Below is the PCAP.

After an hour or two the problem seems to go away.  Rebooting the AP does not help.

The AP is a R550, version 7.1.1.520.830.  I get an error "Create case An Unknown error occurred. We are working to resolve the problem." when I try to submit a case.  What do you mean by WLAN type?

Hi teib2334

What is the controller and AP version that you currently are on and the WLAN type in use ? The above data shows post roaming 4 way handshake is success but a deauth is sent. We would need more debug data to further look into this. But first thing would be to make sure you are on the latest recommended SW. Also if you want quick resolution please log in a case with us using https://support.ruckuswireless.com/contact-us
