We currently have an Aironet 1200 running the most current IOS that we need to upgrade to use WPA2. From what I have read I need to upgrade the hardware to support WPA2 and AES. Has anyone had any experience with the upgrade? We also have some 1100 series APs that take the same hardware upgrade. Should we upgrade those also?
Re: 1200 series 802.11b to 802.11g upgrade for WPA2?
If you upgrade to the current "g" radio, you'll be enabled for AES/WPA2.
You can verify your hardware revs from the Web GUI, under Interfaces | Radio 802.11G | Detailed Status.
It should be something like "Radio AIR-MP31G" (or better) for WPA2.
Installation is not too much of a headache ... I always get a little nervous with those tiny antenna connectors on the radio board ... be very careful to align them properly before applying any pressure ... they're pretty easy to damage.
