Hi all,
I´ve just encountered some curious behaviour of my web-stick “Huawei E 3372 LTE”.
Normally, the connection - once established - is very reliable and I´ve never run into any problems so far.
Well, what just happened was this:
The already existing connection to a 4G network seems to have shut down - all by itself - as suddenly the blue LED was blinking (an established connection is indicated by a permanent blue light).
Hmm, so I waited for a little while, perhaps 20 secs. or so, and the connection was re-established - all by itself again.
Getting curious I looked at the logs with the help of lnav
and found those entries:

I´m afraid I´m not clever enough to make sense of these logs. No idea why “address record” was withdrawn (more than once) and then freshly registered…
I´m pretty sure I didn´t trigger anything off manually. Could it be that the stick lost connection because of any potential problems with the cellular tower (just guessing)?
Perhaps one of you folks can make more sense of it?
Thanks a lot in advance and many greetings.
Rosika
