rt270 disconnects and no reconnects

[jbcfarina]

When I use all the band(transmission or browsing too many videos) it disconnects after few minutes and it doesn't connect again until I reboot.

I could use N and WPA2 by following this thread. If it is possible to reconnect without reboot would be a possible workaround

(I use Ubuntu Karmic x_64)
