Hi christopher, just updated the Bios and still having the issue.

The only workaround I found so far is to disable wireless, then rmmod
the iwlmvm & iwlwifi modules, then insmod the module again and enable
wireless again.

  with laptop unable to open a single socket.

  What I expect to happen?
  If I connect to a wireless network and the AP works fine, keep connected to that wireless network and being able to send and receive packets between the AP and the computer.

  What happened instead?
  After a few minutes or some times hours, some times start dropping packets, sometimes it doesnt work at all.
