I have a small home network - a server and 3 desktop PC's; I have a cable modem, a Netgear 5-port 10/100/1000M GS605 network switch, and I recently installed a new Apple Airport Extreme 802.11n WiFi router to replace a seemingly failing Linksys router. I did not take care to connect the ethernet cables as before as the Airport had at least one fewer ports. Now my network is not functioning. Can you help with some basic directions?
I am connected to the Internet with my MacBook laptop picking up a wireless signal from the router. Sometimes I connect via an ethernet cable and also pick-up the wireless signal for an iPhone and iPad.
