Attached you find the log of my connection attempt. Modem Manager GUI
now says its connected to LTE ("LTE (ETSI 27.007: "E-UTRAN")"), but I
have a very slow ping:
> rtt min/avg/max/mdev = 40.334/411.215/2735.942/452.501 ms, pipe 3
and % packet loss.

speedtest.net from the desktop tells I have a speed of ~1,4MBit. The
mobile phone nearby (using the same operator) has a speed of 5.3Mbit,
and browsing is pretty fluent (so it seems like there are no packet losses).

Do you see anything in the log that could be the cause of the problem?
