Wi-fi disconnecting after a while

[Mauricio]

Hi, I'm new to Linux Mint. I'm using Mint 9 i386 with Genome and have a Realtek RTL-8185 Wireless card.
I used it for a long time in Windows with WPA and never had a problem, but now I switched to linux and it can't work for a long time without disconnecting.
I just installed Mint yesterday and it disconnects after a while if I'm using WPA (seems to last a while longer with WEP). I had the same problem in Ubuntu, and I tried a millions things there to make it work, without luck. Whenever it disconnects I have no other choice but to restart the computer. I'm not using ndiswrapper (but tried it on Ubuntu without luck).

Running lspci -vvnn I get this for the wi-fi card:

And running mintWifi.py I get this:
