Qualcomm Atheros Wireless Connection frequently disconnects

[sonicking]

I posted my issue on a forum and provided some relevant information: https://ubuntuforums.org/showthread.php?t=2360973

Basically, my wireless connection drops on its own frequently. I have to manually re-connect. Someone on the ubuntuforum says my signal level swings too much and this is a bug.
