Hi,

I've attached the two outputs as Working.txt and Not Working.txt. I've also
attached a screenshot of the diff for convenience.

Also, I'm sure now there's some kind of glitch involved. I can get the wifi
to disconnect every time by lifting the computer in certain ways or just
even by squeezing the front gently. However, it also seems to disconnect
when playing gaming and getting very hot.

Shaking the computer some more gets the wifi back sometimes. Suspend/resume
takes it back almost every time. Reboot takes it back every time.

Does it seem remotely possible to be caused by software/firmware/drivers?

Regards,
Kim
