dmesg

Hi there,

this problem has happened for a while now, started with kernel 4.14.1.

this issue seems to happen when a website is struggling with a chocking issue
at their end.  how ever at my end it intermittently disconnects and i am unable
to use the connection at all until next reboot.

i sometimes find my modem router has crashed with such problem.  need to reboot
that too.  i have a NetcommWireless NF10W.  i have not changed the firmware it
came with, and can't find any new firmware.  so i am a little confused to what
this problem might be.

i am enclosing several files to help diagnose this issue.  let me know if you
need more information.
