Do you get any response from sudo iwlist scan

IF not see if the radio is turned off : sudo rfkill list

If it is try sudo rfkill unblock wifi

According to the rfkill listing your wireless LAN (wlan) is not blocked either in software of hardware.

Go back to the ifconfig listing. Both eth0 and wlan0 are shown as UP and RUNNING. Both are working but compare the inet addr. Eth0 is connecting to the router/modem. I do not think that wlan0 is connected to the modem.

On my system eth0 has inet addr: 192.168.1.64 ans wlan0 has inet addr: 192.168.1.65

I do not fully understand the significance of this but I do think that the different inet addr in your case is significant.

Regards.
