Update for LTE modem on LAX20 router

[LNG2000v5]

The Router Update page under Advanced > Administration on the LAX20 router has two tabs: Router Update and LTE Update.

It appears that the LTE Update tab is for updating the LTE Module, but it has never found any new version when I click the button to check for updates on the Internet (I have had the LAX20 since March 2021). There is also an option to manually upload and install an update.

Where on Netgear's site is the download for the LTE module located? I had no trouble at all downloading the .zip file with the latest firmware from the LAX20 support page and installing it on the Router Update tab, but I have not been able to find any download for the LTE module.

If anyone knows where to find the LTE Module download, please let me know!

Thank you!
