I have 2 computers at home, a Windows Vista and a Mac Leopard. I just have a single-user modem that I got from my Internet Service Provider, so it only allows me to connect one of my computers at a time. When I connect my Windows Vista to the modem, the Ethernet light turns on and I can connect to the Internet with no problems at all but when I connect my Mac Leopard, the Ethernet light won't turn on at all.

Thank you in advance!

In my office network I have connected 5 PCs through a router. I want to expand the network with another 5 PCs but I don't have a switch. I have DSL modem. Can the DSL modem be used as a switch or not?

I have an older 3 story  house with wireless internet. The internet is fine on the first and second floor. I have the router in my office which is located on the first floor. The trouble I have is that it gets spotty up on the third floor where the bedrooms are. A friend had suggested a d-link net booster and I wanted to know if that's something a novice could tackle setting up on her own or if I would be better off just having someone come out and do it for me. I'd hate to lose all of the settings already programmed into the router.

As part of my telephone service, I'm using dial-up connection in order to connect to the Internet. When I try dialing the connection, I received this error as shown above. I already tried restarting my computer and connect my dial-up but still, the same error appears. It worked fine last week.

What must be the problem? What should be done for me to connect my dial-up?
