R7100LG not coming online after firmware update to 1.0.0.78

Question

Hi!My R7100LG is not coming online after upgrading it to the latest firmware version 1.0.0.78. Same happens with 1.0.0.76 and the latest verison that works is 1.0.0.72. In fact, it seems that the router does not recognize its LTE modem with the latest firmware. See pictures below.Another forum post suggested to do a firmware reset after updating to the latest firmware - to no avail. Has anyone had the same problem and/or found a solution? Thank you!

It works with firmware version 1.0.0.72, please see pictures above. Sim card does not need reauthorization.

what LTE modem is it connected to?&nbsp;
That's kind of key as a double nat can cause issues.&nbsp;

My post refers to the internal LTE modem of the router, that is, no external device is connected.

Does it work on any firmware?&nbsp;
did you try contacting the LTE provider to see if the sim card needed to be authorized again?&nbsp;

plemans · Answer

Might be your ISP doesn't allow a hot swap of sim cards and the firmware change causes it to look like a different device.&nbsp;
That's why I mentioned having them re-authorize. I can see 1 version of firmware having a bug but if all the newer ones do, it makes me wonder if the ISP is picking it up as a different device.&nbsp;
