Does not go outside the network

Hi to all,
with my Mikrotik LTE from few days, I was experiencing difficulties connecting to the internet, but rebooting RouterOS solved it.
Yesterday, in an attempt to solve the problem I decided to restart RouterOS.
From that moment on I was unable to reconnect to the internet, despite the reboots.
The router is active and accessible via eth, but does not allow browsing web.
I have always used the ssh connection and deactivated any other visual interface.
Could you help me to solve this issue or give me the right way to look into?

Many thanks!

6.42.10 ? That’s an old version …

RBSXTR:
Have you checked the LTE interface ? Is it connected ?

What is the output of
/ip route print
?

The results of the ping point to missing route, not to a connection issue (it would give timeout or host unreachable).

Also, if you could briefly describe your setup it would help, you are connecting via LTE/SIM card, don’t you?

Maybe the issue is on the LTE interface side?
V6
/interface lte info once
or
V7
/interface lte monitor
should give an overview of the situation.

If the gateway/route exists but the interface is down the route will not be in use.

6.42.10 ? That’s an old version …

Yes I know.
But when I asked if the upgrade was safe they replied "sometimes the router becomes a brick… :frowning:

Seems disabled:

Thanks!

I have an SXT LTE (same routerboard, same memory, same storage) and it runs 7.12 just fine.
You don’t have to move to ROS7 if not needed but I would advise to move to at least 6.49.10.

Can you provide following output:
terminal

/inter lte
export file=anynameyouwish

Move file to PC, remove serial number and any public WAN IP info (shouldn’t be there) and then post that file here in between [__code] quotes for easier readability.

I would like to upgrade, but do I run the risk of losing the current settings and having to reconfigure the machine, or worse bricking?? :neutral_face:

Not good.
There is a thread with a few commands to try (suggested by SiB):
http://forum.mikrotik.com/t/lte-cat6-modem-disconnecting-every-2-3-minutes/135493/1

There also reports there about issues with the contacts of the SIM holder/tray, that is another thing to check.

Good suggestion from jaclaz.

Ofcourse it is always advised to make a backup and export your config before doing an upgrade (move those files away from the device !).
But not everyone does it…(guilty too, only when it is a critical device with not really straightforward config, I will make those files and move them away).

Upgrade to latest 6.49.10 should not cause any harm. Quite rare to see problems being reported there (and those are usually the ones you see, success is rarely communicated).

Oh, ok!
You have me put on the right way!
In the next days I will check sim contacts and what if water got into the router! It has currently been sitting on top of the roof weathering the elements for years!

I was interested in understanding if it could have been hacked but the problem seems to be another..

Again (if I can fix it), do you consider the update safe? Do I lose my settings?


Thanks again!!

Thanks again an again!
