Can you follow the "Boot options" instructions on the following wiki to enable additional output on boot:
https://wiki.ubuntu.com/DebuggingKernelBoot As mentioned on the wiki, it would be great if you can attach a log file which may have captured any messages you see. If you are unable to capture a log file, a digital photo will work just as well. As a last resort you can even copy messages down by hand. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1249086 Title: Wireless dies out constantly on 13.10 Status in “linux” package in Ubuntu: Confirmed Bug description: The wifi disconnects constantly. It can take an hour or five minutes. I originally used the normal Network Manager, case in which the connection i was connecting to would actually disappear from the list until i requested the Network to be disabled and enabled again. I changed to Wicd, following a suggestion in another report and the disappearance of the connection was fixed, though it would still disconnect. Everytime the connection is about to drop, the computer laggs. This problem began during Kernel 3.5. I used to boot to that in order to avoid it and the wifi worked flawelessly. Unfortunately with Salamander, that Kernel doesn't start the graphics properly (I get a funky X instead of a mouse pointer). After 3.5, I tried every kernel that was out as they were periodically updated, until 3.11, to no avail. I realize this is a bug diplicated from this bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1115998 and this bug: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1181011 that use my same laptop and present the same problem. Unfortunatelly both bugs have expired. Plus, bug report ettiquete states to file a bug per machine :D Needless to say, I'm not nerdy enough to bisect kernel (read that term for the first time right now) but I'm ready to learn :) Help me Obi Wan Kenobi's, you're my only hope!!
