Whenever I login, my wifi works fine. Then about five minutes later, it disconnects. I try to reconnect, but it won't obtain a connection again until I 

/etc/init.d/network-manager restart

or unplug the wireless card and plug it back in. I am using a Ralink wireless usb card. I haven't been able to find anything on Google about this so I figured I would ask on here. Does anyone know why this might be happening?

I believe my driver is rt2800, but I'm not positive on how to interpret the lsmod. The part of lsmod with that in it is - 

Module                  Size  Used by

rt2800usb              22684  0 
rt2800lib              58925  1 rt2800usb
crc_ccitt              12667  1 rt2800lib
rt2x00usb              20762  1 rt2800usb
rt2x00lib              55301  3 rt2800usb,rt2800lib,rt2x00usb
r8169                  62099  0

So which driver am I using?

One possibility is you have some type of power management that is doing this. What is your wireless driver? And did you activate/install any power management tools? – Chan-Ho Suh Jul 11 '12 at 22:38
No I just did a fresh install to 12.04 before this happened. I'm not sure which driver I have, I edited the question to include some lsmod details. – Sterling Jul 11 '12 at 22:57
this will help somewhat askubuntu.com/questions/162524/wireless-card-power-management/… – penner Jul 12 '12 at 0:40
Thanks, it has appeared to help so far! Can you tell me which driver I have though? Is rt2x00usb the driver or is one of the others up there? – Sterling Jul 12 '12 at 17:11
