    eth1 is wireless. It is also DHCP. Is it connected to a wireless switch/AP? If it is connected does this wireless switch/AP provide DHCP? Without DHCP you are not going to see any IP Addresses. doesn't matter that the interface is up.

    It's wireless card that used to automatically connect to SSID when I had windows on it. At that time using same router I was able to get the IP.

    So I was thinking I should get the same connectivity when I installed linux on this laptop. How do I troubleshoot as to why I don't see IP? Other things look ok, but I am doing it for first time
