I am pretty new to Ubuntu and been using it along with windows 7 since past few weeks. I manage to resolve all those preliminary issues with WiFi adapter(Drivers and all) after a fresh Ubuntu installation. But today it asked for a software updates(not 13.10, just a regular update i believe). I updated and restarted my PC. Since then its not showing any WiFi connections at all. I checked in the additional drivers section in the software updates tab but its all empty. I have a D-Link USB WiFi adapter. The following command gives no output in the shell.
sudo lshw -C network
I remember it used to give some details about my network earlier, but its not showing anything at all. One more thing, the Fifi USB adapter is working fine in windows 7 and also when booting it from Ubuntu Live USB.
