As Phil points out, it's driver/client dependent. If you control your client population, you will likely be able to pre-configure them to your preference.
In response to another posting, I would prefer to have a b/g network for voice only and 802.11a for data only, but most are unable to pull that off. Why that approach? Because 802.11b/g generally has better propagation characteristics and if the network was designed for 5 GHz, the 2.4 GHz coverage is likely very good, which is what the weaker radios in a Vo-Fi devices need. Second, data clients will likely consume much more data than voice clients, and so the large number of non-overlapping channels at 5 GHz facilitate good channel planning and reuse. But because there are so many 802.11b/g clients, implementing a network this way is unrealistic.

Our laptops choose the a network over b-g every time (same ssid on a Cisco LWAPP deployment). All laptops are Dell Latitude models.

Has anyone doing the same run into problems or special consideration that must be minded when running 'a' and 'b/g' side-by-side? On one school's wireless site I found mention of a problem where workstations with 'a/b/g' cards will always select the 'b/g' network over the 'a' network if both use the same SSID. The way they overcame it was by giving the 'a' network a new SSID. Has anyone else had this problem or found a different way to overcome it?
