Although, there is one old software package that can do it on older systems (not likely this is of any help and isn't a free option). The supplicant scans both frequencies, looking for the best SNR characteristics. Your experience isn't unusual as most .11a APs don't provide a hot enough signal to beat the .11bg SNR offered. In most of our companies implementation we see the opposite, but is likely due to our higher RSSI on .11a channels than seen in most all legacy implementations. Not surprising as we use a high gain antenna. Not a sales pitch here - just wanted to point out that different infrastructures will produce different behaviors. Any survey software should allow you to see the SNR characteristics for your area - this should give you a hint of what's going on with the supplicants on your notebooks. On 2/12 Apple delivered an update to Leopard 10.5's wireless drivers. After the update you should see the revs below. 1. Atheros - Wireless Card Firmware Update should be at: 1.3.2 2. Broadcom - Wireless Card Firmware Update should be at: Broadcom BCM43XX 1.0 (4.170.46.3) 3. Intel - Didn't have one at the time of this writing. You might want to try this update as the drivers solve some issues they had with MAC clients slowing their connection speeds over time and not moving to higher speeds as conditions improved. You may also find this changes your supplicant's behavior. Jon 303-808-2666 ...THE ONLY TRUE WIRELESS SWITCH...the Air is the Network...

Anyone by chance knows Leopard on MacBook or Pro (with 802.11a/b/g/n card) wireless preference: does it try a/n first? or b/g/n first? and is there any way to change it? thanks in advance. We have 802.11a and b/g available with same SSID, and find Leopards only connecting to b/g, not a.

I knew 10.5.2 was coming, just didn't realize it was actually here. It is frustrating that something that's 190 MB in size (the 10.5.2 "patch") has so little real information available on it. I dig around on several Mac forums to no avail, and find Apple's site to be almost worthless in this respect- does anyone know where any real detail on Mac updates might be available? Also- am seeing just as many trouble reports as fixes attributed to 10.5.2 during random searches- hopefully it really does help and not set us back even further.

Other MAC users across campus report improvements in wireless functionality on their Macs since the update. Sorry I do not have more specific information.

I'm also getting a sense that the newer Mac laptops (both MacBookPro and Air) that have 11n built in may be somewhat dodgy on our Cisco LWAPP network, though so far the evidence is circumstantial at best. Is anyone else seeing Mac-specific wireless issues? Regards- Lee Lee H.
