I've now seen several posts, including mine, with regards to people having problems upgrading their AP1200's with 802.11g modules:
This leads me to beleive that there may be some counterfeit modules out there on the market and so I was wondering if there is a facility on CCO to check the serial number and validity of the module I purchased?
I've fortunately been able to upgrade my AP with a genuine Cisco, however I'd still be curious to find out how geniune the 'faulty' module is, which I still have in my possesion.
If it proves to be counterfeit, then I'd happily supply the details of the reseller to Cisco!
Expensive lesson learnt!
