ip addr shows the wlan0 interface has the IP adress 192.168.1.65 given 
by the router (is it also a modem ?).
The gateway and nameserver (written in /etc/resolv.conf) should be the 
IP adress of the router.
If the router adress happens to be 192.168.1.1 there is a potential 
conflict with eth0 interface IP address.
