My network isnt working!

[George.Storm]

Hi,
I have set up a wireless internet network in my home, and so this computer is directly connected to the router via an ethernet cable, and then we have two laptops, one with wireless builtin in, and the other with an adaptor, that should connect to it wirelessly.
However, even though at one point they both worked, now, neither of them work at all, and it does not matter what time you try to connect to the network with them, they both say, that you only have no or limited connectivity, and so may not be able to connect to the internet.

Can anyone help me as to why this might be happening?

Thanks

Hi,

Thanks.
