IR302 firmware

IR302 firmware

Hi, i recently bought 9 routers IR302 and 3 of its has a lower firmware v3.5.50, the others has v3.5.59.

Where can i found the newer firmware (in the download section only are available the v3.5.50), the problem that i have is when i try to import the configuration from a newer version to a previous gives an error (in both network and router configuration).


Thanks.
