The following question/answer was taken from a past Wireless Tech Talk. Does anyone know if this includes the 4800 AP when upgrading from 11b to 11g? Or is this for 340's/350's only!
What is required to upgrade AP's from .11b to 11g., then from .11g to .11a? The migration from 802.11b to 802.11g is expected to be accomplished via a firmware upgrade, however, from 802.11g to 802.11a will require a hardware change, as it will use a different radio.
