Re: Client disconnects randomly

Hi Colin,

 

the one being debug is an android but customer also report seeing this behaviour in apple devices.

ArubaOS ver 6.5.2.1, i will suggest them to upgrade if we cannot make any sense from the log.

open encryption.

Re: Client disconnects randomly

Is the client using 20/40 or 80 mhz channels?

Do they have "Drop Broadcast and Multicast" enabled on all of their Virtual APS?

Re: Client disconnects randomly

all 20. i turned off all channel bonding.

"Dynamic Multicast Optimization", "Drop Broadcast and Unknown Multicast", and "Convert broadcast arp to unicast" are all enabled

Re: Client disconnects randomly

You should enable user debugging to see why your clients disconnect.

EDIT: You already did that..

 

Looking at the debug, it says that your client just ages out (does not respond).  You should open a TAC case so that they can gather more detailed information.

Re: Client disconnects randomly

alright i'll do that.

also, they are using RAP bridge mode, does that affect the client connection and roaming quality?
