HI Gerry,

As you are business client please contact us via email directly. Someone will take care of you.

Until now we only have report for AR300M lost configurations but Not MT300N. MT300N use Nor flash which is very stable.

There is only one situation that MT300N will lose it configuration: the flash is full because too many data is written in it.

By the way, please let the users upgrade to firmware v2.261 which is just released.
