LTE problems, cdc-wdm0 not found

I have been using LTE on my turris for a few months and it has been working fine. Yesterday it wasn’t working when I got home from work, so I haven’t messed with the configuration. Double checking against the manual I found the uqmi-command but all it returned was.
root@turris:~# uqmi -d /dev/cdc-wdm0 --get-signal-info
Failed to open device

Looking through dmesg i found
[ 14.765890] usbcore: registered new interface driver cdc_wdm

Does anyone have clue of what the fault could be?

Update, using Schnapps I’ve rolled back to the config I had 2017-04-13 and now it’s working again. What have changed in the meantime?
