MIB for WNAP320 V2.1.1

Hello,

I know that it's kind of stupid, but here is my problem :

I got some WNAP320 running at a client company, and I'd like to monitor through SNMP how many clients are associated with each one. I know that the OID should be ".1.3.6.1.4.1.4526.100.7.9.7.5.1.8.24.1" but the resulsts I get are not consistent with what the web interfaces show me, so I was wondering wether it could be cause by the old firmware (they all are 2.1.1).

I know the obvious solution would be to upgrade them all, but I can't right now, and can't find the MIB for 2.1.1.

Is there any way of finding the MIB for older versions of the firmware ? Or just the OID for clientAssociation...

I've tried contacting support but there is a wrong redirection there so I hope someone who knows the answer will be kind enough to answer me !

Thanks in advance
