Ubuntu – 15.04 32 bit unstable wifi

So this has been a long time problem that I hoped would get fixed with some software updates. My desktop machine has been having wireless connectivity problems since an update on 14.10 and now I have installed 15.04 and replaced the network adapter yet my problem remains. Replacing the network adapter seemed to help but not completely resolve my problem. I can connect to my wireless access point but the connection periodically just drops and I have to restart the computer to get it back. Now for some basic info to help:

ifconfig
