Wifi is working fine for some time then it stops working. Wifi icon shows that all is fine, but there is no connection and I can not disable wifi through GUI. Network Tools GUI utility also don't start up. I am not able to restart or disable wifi through the console because some console programs like sudo, iwconfig, ifconfig stop working too when those lags appear (after I launch the program nothing happens and ctrl+c escape sequence also don't work, so I am forced to kill the terminal program). I am using ndiswrapper and wg311v3 driver.
Thanks in advance for your answers.

I'm having the same problem - completely fresh install a few days ago of 64 bit Ubuntu. I have a USB wireless card that I'm using WUSB54GC. The symptoms are exactly the same as the OP, network activity stops including the green light on my card. The indicators look completely normal except the lack of Internet.

I can fix the problem by removing the USB cable from the NIC and waiting a few seconds. This gets me pretty much instant access again, until the problem rears its head again within the hour usually.

I'm pretty sure my issue is related to using Transmission to download a torrent. The problem doesn't seem to happen or nearly as much if I'm not pegging the Internet connection with Transmission.

OP...you wouldn't happen to be downloading torrents would you?

Could you give me the output of these Terminal commands?

sudo /etc/init.d/networking restart
sudo ifconfig
sudo iwconfig
sudo nm-tool
lsb_release -s -c
uname -a
