Q: Airport Express Set Up to Extend Wireless Signal

I have a new iMac that's linked by ethernet cable to a modem and to a Netgear router.  The house is two-story and thus the wireless signal is not very strong in some first-floor rooms (the iMac is on the second floor).  I bought an AirPort Express to extend the wireless signal, but can't get it to be recognized by the iMac.  I have installed the Airport Utility software and asked the Airport Utility to search for existing Airport bases.  It can't find any, even when I have the Airport Express base plugged into an outlet in the room with the iMac.  For extending the wireless signal, is there more to do besides plugging the Airport Express base into an existing outlet?  I don't need it for remote printing, loud speakers, etc.

Sorry, I just used my network as an example that the AirPort Extreme or Time Capsule alone may be all that you need. However, I would recommend that you get either and use it in conjuction with your AirPort Express to create an extended network.

    Greetings!

     

    The irony here is I AM using a non-Apple router (Buffalo Air Station Nfiniti) on a 64 eMac to boost a wifi signal and it works very well with minimal fuss -- but I can't get my XP Dell 260 to use it!

     

    This wireless router's IP is 192.168.11.1 (ON) and 192.168.11.100 (OFF), and I've spent hours with the Connection Wizard thing on XP trying to create a ethernet path to the router but I can't find a configuration that states an ethernet path or channel. The modem lights normally and other machines can pick up and connect with its signal but there's no real transmission, the receiver machines getting:

     

    Firefox can't find the server at http://www.acorn.com.

    Check the address for typing errors such as ww.example.com instead of http://www.example.com

    If you are unable to load any pages, check your computer's network connection.

    If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

     

    Ironically, the router works just great on the Macs, which has both Airport on to receive signals from a cable TV wireless router and also has its shared Ethernet connection on, and the ethernet side requires no IP configuration like it seems you must on the XP's internet connection page. The router in question just plugs in the Mac and transmits just fine. I would use the Mac for this purpose but I really wish to use the Dell.

     

    The Dell's fail network configuration after many trials:

     

    Wireless Connection 3

    LAN / High Speed Internet

    Connected, Firewalled

    802.11n USB Wireless LAN Card

    IP 169.18.2.7

    Subspace Net 255.255.0.0

    No Default Gateway

    =====

     

    MAC's working Config:

     

    Airport

    DHCP

    IP 192.168.0.14

    255.255.255.0

    Router 192.168.0.1

     

    Ethernet

    DHCP With/Without Manual Address

    IP 192.168.11.1

    255.255.255.0

     

    Oddly, the Mac's Network panel states: "The cable for built-in ethernet is connected, but your computer does not have an IP address and cannot connect the internet." Yet it does!

     

    Any assistance would truly be appreciated!
