So I have an airport express that extends one of my networks. Can I use an ethernet cord on this and plug it into my computer for Internet? Please help ASAP. Thanks!
You sure can. I use AP Express devices in my house to extend the network to devices that don't have wireless.
As bamf-hacker says, yes you can. You can actually use both ethernet ports (on the latest version), even though one is set up as a WAN port... if you?re using the Airport Express in "bridge" mode (wirelessly extending your network), both ports area available for ethernet connections.
