I suggest you test your RAM as a good starting point. Ubuntu comes with Memtest86+ which is accessible from GRUB

markus (markus-n3) said : #2

memtest came back clean, no errors there. Any other suggestions?

Manfred Hampl (m-hampl) said : #3

For diagnostic purposes please provide the output of https://help.ubuntu.com/community/WirelessTroubleshootingProcedure

Jeremy (wa113y3s) said : #4

I would suggest filing a bug report against package bcmwl-kernel-source as this happens quite often
