hi,
i've got a bunch of 1242 (SKU: cisco AIR-AP1242AG-A-K9) standalone APs and would like to re-use for a client that requires WPA2 for their security requirement.
it currently doesn't support WPA version 2 although it supports AES CCM.
i did some searching and was pointed to use 12.3.8JEC. my question is would the IOS c1200-k9w7-tar.123-8.JEC3.tar will work or is it compatible with my 1242 AP?
the 12.3.8.JEC notes only specified to work on a 1232AG. was wondering if someone tried on the said AP and if it worked before i suggest buying new AP.
