I have two laptops at home. With one I am able to net connect wireless. The other machine do not connect to net. Router manufacture suggested that the issue is with my machine & it has got a fixed IP address & so it is not allowing router password to be assigned to it. (Not sure what it means)
I am able to connect to net on this machine only when I am connected with cable.
Can anyone help me with this.

Does it have a fixed IP? If so, why?

Yes, It has fixed IP address. I have no idea why. I need help so that the IP address can change when connecting with wireless router. Thanks for your help in advance
