I had weird issues like this when I was upgrading across different versions in stable. So I imagine you need to print the settings you put in IPFire through the web gui, and download and install the Jan21 download and reload the settings. Because I don’t trust it backing up the settings across different versions. Maybe this is unnecessary, but at least you have a paper copy of your settings.
The I would go a step further and change the distro type to testing and use the new Linux kernel because they did fix a few usb drivers and my usb ethernet (ASIX) works correctly. I did update from 189 to 190, but some of the default firewall rules were different than it should be and the previous 190 iso I downloaded in December had the same issue when I loaded it on a replacement machine.
