I ran the setup and everything seemed to work okay. My computer (running Windows 7) as well as my brother's (also 7) who is a few feet away from me are using wired connections. My friend on his laptop (Vista) behind me connected wirelessly. My father (Vista) has a LAN cable that runs down to the basement, but he CANNOT connect now. This is the same exact setup we used previously, and I can't figure out why we are connected but he is not. I can see everyone else in the network when I go to the network control panel. We've tried restarting his computer, re-plugging his LAN cord in and plugging it into a different port.
On a side note, I attempted to download a new firmware update for the router, and I think it updated? The browser got stuck on "restarting router" and I had already watched the light restart...and my computer somehow didn't have internet while the two behind me did. I ended up logging off/on my windows profile and then re-connected my LAN cable from the router and that seemed to do the job for me.
Any ideas how to get my father's computer connected from the basement? He has the oldest computer of all of us, and we are already setup for his wired connection but just cannot establish him in the network.
