Re: SSID sometimes dissapear

Does this happen to both bands?  Possible that there are radar events causing the 5GHz radio to cease transmission for a time whilst it checks a new channel.

Is it only happening to 1 x ssid or all?


If my post is helpful please give kudos, or mark as solved if it answers your post.

Hudaya,

 

What are you using to see the SSID?  Sometimes if there is alot of congestion in the wireless spectrum, collisions would make an SSID seem like it has disappeared.  In addition, the device that is looking at the SSIDs could miss beacons based on its own scanning algorithm.  I have seen this mostly outdoors with alot of interference and with android devices.

Re: SSID sometimes dissapear

We need more information.

 

What version of Instant?

 

How many SSIDs are you broadcasting?

 

What is the minimum and maximum transmit power of your access points?

 

Do you have Broadcast Filter ARP or Broadcast Filter all enabled?

 

Are clients on the 5ghz band also getting disconnected

Re: SSID sometimes dissapear

On the commandline of the controller, you should type "show log system all" or "show log wireless all" to see if there is any evidence of something that could be wrong..
