Here is the scenario. I have an AP 1200 with an 802.11a and 802.11b antenna. As most would guess, when you leave the a antenna range, the dual-band client falls back to the b antenna. But, when the client comes back in range with the a antenna, it will not negotiate back to the a antenna. Does anyone know of a quick way to negotiate back to the a antenna without going through the many steps of disabling and enabling your wireless nic? I have some users, who know enough to cause problems, complaining about this.
