Leopard Wireless Dropouts - Tried all reccomended forum fixes - need help

Question

I need to add my name to the list of people who are having genuine problems with the wireless networking in leopard. I am the primary systems admin for a school, and responsible for maintaining an install base of over 250 intel macbooks. Since upgrading to leopard we have had many many wireless issues.
We have 3com wx1200 wireless controllers running numerous 3com 3750 and 2750 access points. The security is WPA2 with PSK authentication (though I can shut the security right off without any improvements in reliability). Macbooks will consistantly drop the connection to the wireless requiring a "turn airport off" and "turn airport on" to re-establish the connection, which works about half of the time.... Many times the machines need to be rebooted. It seems as though our original core duo macbooks are the most affected, though the problem exists on all our macbooks running leopard. (currently 10.5.5) *Rebuilding any of the affected laptops with tiger instantly clears up any problems*. No tiger machines, and no windows machines have any issues with the connection drops. I've tried every documented suggested fix on the numerous other threads here where people are having this exact same issue. I've eliminated all the variables and my problem seems to be leopard alone, or perhaps leopard in conjuction with this particular wireless infrastructure. Regardless, it's time that this problem is officially acknowledged and that some strides are made to remedy it. I'd be very happy and available to work with apple engineers on this problem. I can provide whatever logs or dumps you need.
This is one of two unacknowledged widespread issues that is shooting us in the foot. We are also plagued by the problem where faulty parental controls partially restrict access to secure sites (in our case google docs). This bug is also all over the forums and goes unresolved.
Any ideas or suggestions (other than permissions repairs, keychain repairs, and upgrading router firmware - it's all been done!) would be most appreciated!
Cheers,
Neil

Answer 1

These are actually user to user forums - a place for fellow Mac users to get together and swap troubleshooting ideas.
However Apple Engineering does not read these boards on an official basis, so we can complain about something all day but until it makes its way through AppleCare to engineering it won't get on the engineers' work queues.
The other way to file a bug is to register for a free Apple Developer Connection Online account, which will then allow you to file bugs via the Apple Bug Reporter.
