This firmware was installed on the modems at the factory. Trying to improve the operation of the modem, updated to version RUT2M_R_00.07.02.7
The modem has stopped registering on the network
Other firmware versions RUT2M_R_00.07.01.4 and older do not enable 3G data transfer mode
Where can I download firmware RUT2M_R_00.07.01.6?
