Wifi (pci) disconnect when computer idle. Fedora 14, wifi RaLink RT2561/RT61

Hello All,

I have a problem with my desktop pc for which I bought a wifi card (Dlink dwl g510, chip RaLink RT2561/RT61). Fedora 14 detected it automatically and wifi seems to work great on the machine.
The problem comes when I try to ssh into my machine from my laptop over the wireless. If I don't use the desktop computer for a while, it will stop responding to ping, and will only respond again if I go to the computer and use the internet. (It never shows the network as disconnected, so it doesn't loose the signal).

So from this I deduce there is some sort of idle poweroff happening, but when I type iwconfig I get this:

Code:

wlan0     IEEE 802.11bg  ESSID:"***"  
          Mode:Managed  Frequency:2.462 GHz  Access Point: ***  
          Bit Rate=48 Mb/s   Tx-Power=20 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=50/70  Signal level=-60 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

which says there is no power management activated. I can't find any error or log about this problem, so any suggestion on where to look for clues would be very welcome!

Thanks ahead for any help,

Btw, could this be a driver bug?
