I have several air-pci352 cards used with a 1200 AP. I was wondering if the air-lmc350 module(contained on the pci card) can be replaced to support 802.11g. We are upgrading the 1200AP to 802.11g when available.
You can upgrade an AP1200 from 802.11b to 802.11g by replacing the internal Mini-PCI radio. This upgrade module will be available in November. This will require an IOS upgrade as well, also available next month. You can additionally add an 802.11a CardBus radio to achieve dual band support.
