How do you know the settings are configure exactly the same? Did you manually configure every setting through a "stare-and-compare" process or did you export the WLTNA from the MC9190 and import it into the MC92N0? If you're manually configuring the devices by hand then you are missing a ton of settings that are buried in the Emulation Parameters that aren't exposed in the device based configuration.
It sounds like you need to re-configure the Number of Sessions setting from the default of 1 to 2.
I have exported the WLTNA from MC9190 to MC92NO. Even tried re configuring the Number of Sessions setting from the default of 1 to 2.
is there any other settings.
