I have a new dell inspiron 15R with intel i5 3210m processor.
When I toggle the wireless switch on it shows bluetooth on but no wireless networks are shown even when the network is available and connecting on the other windows os.
So what to do ? I want to install some updates on my ubuntu system and I only have wireless connection.
SO Please Help me to get connected.
