RUT950 --- LTE not connected / not stable

NETWORKING SOLUTIONS
1

Hello,

Unfortunately I am very frustrated at the moment because I now have the second router with the same error.

I bought a second-hand vehicle in which an RUT950 is installed. After a factory reset, I installed the latest firmware and inserted the new SIM card (tested in a mobile phone).

No connection was established for about an hour. Then, however, when playing with the APN, it worked for a minute.

Status now:
Connection is established after a few minutes, then persists for 2-6 minutes and then drops out. LEDs go out and apparently the interface is restarted.

All stable firmware versions have been tested, no improvement.

Please support me

Thank you

Troll

Can you upgrade to 07.06.16

And then make sure you’re on IPv4 only and Auto APN

Please try suggestion from @TeWe. On the hand, module firmware is very old and can cause some issues here.

Done!

Now, it is even more unstable.

LED:

  1. flash green/red → 5-10 sec
  2. flash green and indicate reception (4 LED) → 15-40 sec
  3. goto 1.

Can you reset one more time to factory defaults before going anywhere else?
After factory reset, IPv4 and Auto APN again.
Let’s see how it goes then.

I did the update - since then it works reliable.
