RUT950 disconnected from the web

Since Yesterday the modem was working correctly, after update the computer to latest windows 11 ARM64 patch, preview of 23h2, and after reboot computer the RUT 950 lost the internet connection.
this happened some time ago with the SIM1 bay, but I exchanged to SIM2 bay and there were no problem and connection stabilised till yesterday.
to be sure that was not the computer I bring from home one Zyxel LTE-4506-M606 and I used the SIM card of my RUT950, and the connection is perfect. so, I guess that should not be a problem of security system, etc. should be a problem of the modem itself.

the modem is installed in my boat, and I really need the internet access for update of navigation software, o.s., charts, etc. and also, comms.

Hello,

The first screenshots shows that the mobile data is disconnected. However, the logs show that mobile data is connected. The logs also show that the LAN port speeds are changing. Hence, could you please clarify if the issue is with the mobile connection or the connection to the device via cable?

Have you tried connecting to the device via WiFi?

Kind Regards,

Hi,
after event id 3202 of the log is clearly shown that mobile data are disconnected and I was unable to surf internet, neither retrieve mail, etc. I’m windows 11 user and the network icon exchanged at that time from the networked PC to unconnected world.
I tried many situations with PC, of course I activated the WLAN in my PC via router with no success.
I exchanged the SIM card to the mentioned router Zyxel, and the connection was correct, so, there was not a problem of SIM card.
I also did a tethering with my mobile and no problem.
I did some restarts of the modem with no success, always showing me in “data connection” as “disconnected”.
on the next day by error, I recover the initial setup of the router, instead of another newer configuration and after that the connection was stablished, to say that I nearly have to configure the option from the scratch, because I have on the boat some fixed IP according MACs. and some other options too.
I have the modem version of the attachment, is there another newer version?

also, in case how to download and apply?, because in the router web page and switching setup as “advanced” I cannot find the option CLI (Command Line Interface), but never mind because I have installed in my computer Putty for windows ARM64 (computer is running also in windows 11 Pro ARM64) so I can do it if necessary, accessing with that software.

To remark, that in that situation, I was able to access the router from the computer either LAN either WLAN, I never lost the connection with the router, bearing in mind that I have software that uses the router as switch and that software was working correctly retrieving the data from the sources but of course not getting data from the web.
is the case that I have one NMEA 0183/N2K/LAN multiplexer connected to router and serving data to my computer (LAN) and my tablet (WLAN) via UDP. and those connections were active and working while the problem raised, the only thing that none of them were able to retrieve data from the web.
also at that time, when I arrive on board the mobile connects itself to the Wifi boat’s network and at that time was connected too but telling me that Wi-Fi network has no internet access.
some minutes before I was working with mobile checking parameters of setup of the router via its Wi-Fi without any problem.

Hello,

Just to confirm, the connection is functioning correctly after you reset the device to its factory settings, correct?

As for the modem’s firmware, it’s generally not advisable to update it unless you’re experiencing problems connecting to your mobile operator. Therefore, if the connection is working fine following the reset, I recommend avoiding any updates to the internal modem’s firmware.

Kind Regards,

Yes,
the connection is working now.

what really, I find tricky to edit are the APN data and to go to advanced configuration to set static IP of devices connected, I didn’t remember how to do it from last time I did it, but after investigating a little bit at last I’ve done it.

thanks for the info of modem firmware.

Hello,

I am glad to hear that the device is working properly now.

If you have issues with some of the configurations, you can always refer to our wiki page here. The search functionality on the wiki can be used to find relevant information.
