http://ubuntuforums.org – I've had this issue on two separate machines. I'll be surfing the internet, then I'll all of a sudden I'll lose my connection to my route. GNOME wireless applet says I'm still connected and when I check ifconfig I still have an IP. But when I try and ping my router it says "Destination Host Unreachable". I'm having this issue on a Toshiba L670 and a Toshiba NB505. Sometimes I can disconnect and reconnect and get it working but it only fixes it for a moment. Other times it won't reconnect. I try bringing the wireless card down, ifconfig eth1 down, and then back up but that work (Hardware)
