Can't connect via wireless...adapter not working?

I'm having an issue connecting to the internet via wireless on my Studio 1555 running windows 7. Sometimes it can detect wireless networks, and sometimes it cannot (red X over wireless symbol). Our router is working fine according to my housemates, and I can get on the internet via physical connection using an Ethernet cable. What's especially odd, is that sometimes when I first turn on my computer, I can connect to the internet briefly (open my homepage), and then it disconnects/shuts off. This only happens occasionally and gives me false hope, ha!

What I've already tried:
1. double checking my wireless was on (via F2)
2. Making sure my power settings were not shutting off wireless
3. Tried updating my IP...but couldn't because I got "no operation can be performed on wireless network connection while it has its media disconnected:
4. Got a "device is working properly" from device manager

Here is what I got from ipconfig /all

C:\Users\Allison>ipconfig /all
