Client associates and immediately disassociates

Hi,

 

i have an issue with a legacy b wireless client. We are migrating some old client devices from a Motorola Symbol wireless system to Aruba but one client fails to stay connected. The client works fine on the Symbol system so there must be a mismatch somewhere with the Aruba kit. I have enabled debugging but do not see anything useful in the log apart from the client does not report an IP address when being placed in a role (via derivation rule).  All the clients are statically addressed and all work aprt from this one. As soon as i switch back to Symbol it works. SNR is very good at >48

Some detail from the log below

Re: Client associates and immediately disassociates

 

Do you have band steering or spectrum load balancing  turned on by any chance ?

Thank you

Re: Client associates and immediately disassociates

No, neither are enabled, it is 2.4Ghz only

Re: Client associates and immediately disassociates

Can you please share the ACL s under the user role?
Thank you

If it is a Motorola device, please check out this article here:  https://arubanetworkskb.secure.force.com/pkb/articles/Troubleshooting/Why-Motorola-MC2180-bar-codes-is-unable-to-connect

 

If it is not, please tell us what make and model the device is..

The client bridge is a 3 Com CB3000 (I believe this used to be manufactured by Motorola). I enabled g rates but it had no effect and I also enabled 802.11d which again had no effect.

The client associates for a maximum of 3 seconds. I have forced the AP to several different channels but still no luck.

There are two other CB3000's that connect fine and as far as I can see have the same settings.

Re: Client associates and immediately disassociates

If you put all three 3-COM devices in the same area, would two of them connect and this other one would have a problem?  If so, I'd think you're wasting time troubleshooting it as an infrastructure issue and would go ahead and reset the device.

Re: Client associates and immediately disassociates

All 3 devices connect immediately to the Symbol infrastructure but one will not connect to Aruba when I switch the AP's. I will try resetting the problem device
