Hi,
I just installed 19.07.5 on a D-Link DWR-921 and then activated the LTE modem as described here in the 'alternative configuration' section.
So far, everything looks normal. However, there are some warning messages in the system log.
Unfortunately, I don't have the knowledge to understand them. Can somebody please take a look at them and tell me if there is a problem? Thank you
These are the lines I mean (if it is necessary to post the complete system log, please tell me):
