macbook pro, mid 2010: wifi dropping out

[scotthew1]

My wifi drops out randomly sometimes lasting hours sometimes barely one. I think it might be a hardware issue, but the fact that a reboot fixes it has me questioning that slightly. Does anyone have any suggestions for things that might fix it via software before I'm sure it's hardware that needs to be replaced?

Things I've tried:
Turning the wifi off and back on again. This puts the computer in a confused state where it doesn't seem to know if the wifi is on or off. See picture [1]
Choosing a different network. It'll drop out both at home and on campus routers.
Deleting the wifi as a service in the system preferences and re-adding it.
Reseting the SMC.
Reseting the PRAM.
Reinstalling Mavericks.

While having the computer in a position that you've had problems at and connected to your Wi-Fi, option + click on Wi-Fi in the menubar. What is your "Transmit Rate"?

I'm waiting for it to drop again, but while it's been working I've seen it range from 108 - 216. What would you expect when it's not working?

I can't view that info when it's not working.
