AirCard 785S problems: DHCP not working, factory reset not possible, does not connect to to mobile n

I have an AirCard 785S, no network lock, bought in Italy and working perfectly for about 6 months both in Italy and Germany.   Suddenly a message "Update failed" appeared. I never asked for an OTA...

Hi,

 

Can you please confirm what AC785 SKU you have.

SKU version is printed on label under the battery.

If you purchased the unit in Europe, then it is unlikely that you bought a Telstra SKU.

The firmware download link you've referenced will only work on Telstra SKU'd devices.

 

What state is the unit currently in?

Does it power up and can you access the internal web page on 192.168.1.1?

If so, can you confirm the firmware version currently on the device.

And can you check that your APN is still set correctly.

 

Thanks

Steve

    Hi, thanks for the reply.

     

    The unit is:

              NetGear Aircard 785S
    SKU: AC785-100EUS
    TA: 100-19123-01R15

    bought in Italy.

     

    As I said in my post,

    • The unit boots
    • I can connect to it throuth USB tethering, but only IF I set a fixed IP in my laptop
    • This is the info output (private infor blanked out):

    • I cannot change ANY parameter in the configuration:
      • I can set a new value for a parameter in the web UI
      • I save it (apparently)
      • It does the usual reboot
      • After the reboot everything is back as before: apparently it cannot write the new value in the memory
    • I CANNOT do a factory reset: it say "shutting down", but it gets stuck there forever, until the battery is flat or I remove it.
    • The APN is correct, but this has also nothing to do with the problem.
      The device should be able (and it was able) to deliver a DHCP IP also if I am not connected to the GSM/LTE network.
    • Anyway, it stays forever in "connecting"

    Thanks for the help.
