Apple continues to document that iPad wireless issues on corporate networks are not widespread, but this does not seem to be the case. We have isolated iPad issues down to mixed modes - B/G, G/N, etc. If you run one standard (e.g. G) connectivity is stable, but when you run two standards on one band connectivity is incredibly unstable. This presents a challenge in a larger part of our environment because we use 1252's with G/N on 2.4ghz. Disabling N diminishes performance and disabling G limits the devices that can connect to our network.
We are currently using both WPA and WPA2 with PSK and/or certificates - both have challenges
Has anyone found a viable workaround for AP configurations or client side on the iPads themselves?
