Q: G4 (800MHz) connects to airport network via N300 wireless modem but won't bring up a browser page (Safari or Firefox)

G4 (800MHz) connects to airport network via N300 wireless modem but won't bring up a browser page (Safari or Firefox) - so the connection is there, everything says its a goer  - I get a clear black signal icon in the menu bar on top, and a clear signal strength in the Internet connect dialogue box -  - but when I run either of the browsers, it just says 'not connected to internet' - even for the 'software update'.
the N300 is a Netgear N300 Wirelsess Modem Router (model DGN2200) - ADSL (802.11 b/g/n)

    tests to try:

     

    -- have you tried connecting by cable?  What happens?

     

    -- Set your dns to 8.8.8.8 and 8.8.4.4  This is the google dns server.  generally faster.

     

    Check out your settings. 

    apple > system preferences > network

     

    Double click on network connection you are using.

     

    Pick the TCP/IP tab.

     

    Verify that you have a DNS Server.

    You can use

    harddrive > applications > utilities > network utility

    to diagnose the situation.

     

    You can ping google.com.

    If pinging 17.254.3.183 works but pinging Google.com doesn't. You have a bad DNS Server address.

     

     

    I use Google.

     

    Google provides free dns lookup.  Their numbers are:

    8.8.8.8

    8.8.4.4

    Is the wireless frequency available to the old PPC G4 800MHz computer compatible

    with any of those provided by the newer model base station choices? I doubt it.

     

    Usually one of the issues is secure settings, as they are obsolete in the old hardware

    limits and later ones generally do not apply. Try Ethernet to go online, then look for

    a vintage AirPort express (early version) or other AirPort Extreme, and set it up for

    use with the older gear so anything newer will not be compromised by running your

    entire wireless network with no security at all. WEP, WPA, and the series of frequency

    available to the older hardware is where the problem very likely is now.

     

    Good luck & happy computing!

    yep -have to give this a go.
    already have an older airport card - but it could well be those WEP security things 
    Found out it does work via ethernet. I was going to try an externalUSB Wireless dongle -whenIfind it - but then rremembered that the old 800Mhz was only USB1

    Thank you very much for your input and for replying

    I think you might be right about ti being a security thing.

    A USB wireless adapter should (normally) work even under USB 1.1, but at a limited speed. For Internet connections below approx. 10 Mbps this could be OK. However, the main problem with the USB adapters is that they need special drivers, and this will be an obstacle for early operating systems. Always check the system requirements for a particular USB device.

     

    A good alternative would be a wireless Ethernet bridge (also known as a gaming or media adapter) connected to the Ethernet port of the desktop computer. A wireless Ethernet bridge (typically) works without special driver software, and can thus be used under almost any operating system. Modern devices (Netgear WNCE2001 and Linksys WET610N are merely two examples) can handle the latest security standards.

    Well, you apparently DO learn something new every day    - wasn't aware at all of this  "wireless Ethernet bridge" - lots of other ideas for workarounds, sure, but not this - so thank you; I'll go research it!

     

    cheers
