About four days ago after installing routine Ubuntu updates, my wireless networking (and I believe networking in general) does not initiate on boot. It takes on average 6 reboots before networking starts again. Not sure if I am doing something on the user end that initiates a change.
Here are some logs recorded while networking was not working:

I'm not sure what is going on that the networking would sometimes not work and once in awhile start working.
Also, the last two restarts I have disabled networking before restart, and enabled after boot up, and networking has worked. ?
Thank you for the help. Let me know for any more logs please!
Edit June 28: After updating Ubuntu again networking is not working at all... Any ideas???
Edit July 31: Same symptoms after many updates. Am able to get wireless occasionally on reboot, and haven't found any pattern so far as to why.
