I've never tried this before and after hours of working at this I'm seeking help.

I have two desktops, one a Sony Viao and the other a Dell.

I have a wireless router which the first computer (sony) is plugged into and it works fine. I ran an ethernet cable from the second computer to the wireless router which I thought would grant me access to the internet and ultimately file sharing but I cannot get it to work.

Any suggestions. I have never attempted this before.

Thanks much
