The AP is in FlexConnect/H

The AP is in FlexConnect/H-REAP.  

 

1.  Check the latency between the AP and the WLC; 

2.  Check the uptime of the AP.

Hi Leo, i have enable Link

Hi Leo, i have enable Link latency in one of the AP´s and i get this after some days

So, i remember that if we have Ap´s in mode flexconnect the latency must be less than 300mSec and minimum bandwitdh of 128kbps

 

with the image i cant say that the Ap´s sometimes experiments latency (for one reason, no matter what) maybe only for a few "minutes" and that's why i have disconnections of the AP´s from the WLC, right?
