I'm trying to help a friend who has an iMac G5 running OS 10.4. with an ethernet connection and a Netgear router.  AT&T/SBC is her ISP.  She had no connection to the Network at all but I've didled with the settings including re-installing the router software.  Now, she has an unstable connection to the Internet but neither Safari nor Firefox will load any site even when everything says it's connected. 

 

When I run Network, Assist Me, Diagnostics, all lights are green.  The modem will then occasionally flash red and lose the Internet connection even while I'm looking at Network Diagnostics showing all green and connected.  Then the modem will find and return to solid green for Internet.  Throughout all the solid green connections, Safari/Firefox will not go out and find and load any bookmark or new site.  I assume I've missed something in the Network settings that's causing the instability and failure to run a browser.

 

Any suggestion to correct the Network settings would be appreciated. I assume that will fix the browser problem.  Thanks.

 

BTW- She says it started when AT&T/SBC announced they were making email connection changes this month but I'm uncertain how that would change her ability to connect to the Internet.  I think they're separate issues.  Hopefully, I can fix the email problem (settings) when the Internet issue is resolved.

iMac, OS X Mountain Lion (10.8.4)

    10.5, 10.6, 10.7 & 10.8…

     

    System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.

     

     

    10.5.x/10.6.x/10.7.x/10.8.x instructions...

     

    System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.

     

    The interface that connects to the Internet should be dragged to the top of the list.

     

    For 10.5/10.6/10.7/10.8, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...

     

    208.67.222.222

    208.67.220.220

     

    (There may be better or faster DNS numbers in your area, but these should be a good test).

    Click OK.

    The interface that connects to the Internet should be dragged to the top of the list.

     

    10.4 instructions...

     

    Is that Interface dragged to the top of Network>Show:>Network Port Configurations.

     

    Also might try putting these in Network>TCP/IP>DNS Servers:, for that Interface...

     

    208.67.222.222

    208.67.220.220

     

    Apply. These Servers have been patched to guard against DNS poisoning, and are faster/more reliable than most ISP's DNS Servers.

    BTW- I just noticed that my Service Order was not set properly and hasn't made a difference ... so ... can it be that as a fix?

    It could be, OSX tries from the top down for Internet, and may try the wrong order, yet it seems DNS is part of the issue.

     

    Also, to possibly save a trip...

     

    PRAM reset, CMD+Option+p+r...

    In fact, do 3 in a row, takes a bit of time.

    OK, good luck... looking forward to hearing good news!

  • rccharles Calculating status...

    Is this wired or wireless?

     

    If wireless, turn off password until you get it to work.   Try an ethernet cable connection.

     

    You need to get some other device connected & see if that device works.

     

    I had my iPad and a hotspot so was able to search and enter 2 ATT/SBC DNSs.

     

    Not sure what you are saying here.

    Now, she has an unstable connection to the Internet but neither Safari nor Firefox will load any site even when everything says it's connected.

     

    You can download these browsers at your place. Put on a dos/fat32 drive.  Do not expand.  On the mac double click. In general, drag to applications folder.  Or drag to shortcut icon.  Might have to double click on the resulting folder or virtual disk drive.

     

    Well, this isn't the communications problem, you'll need to ensure you have the latest browswer.  FireFox doesn't work with all sites.

     

    I run TenFourFox on Tiger.

     

     

    TenFourFox -- It's a port of the latest FireFox to run on older hardware and software.

    "World's most advanced web browser. Finely tuned for the Power PC."

       --  works for me on 10.4.  Supports 10.5

    alternative download site:

    http://www.macupdate.com/app/mac/37761/tenfourfox

     

    OmniWeb uses the lastest Safari framework.  The open source WebKit. Other browsers like Safari and iCab use the OS version of WebKit.  The OmniWeb downloaded dmg includes it's own copy of the latest WebKit.

    Could be a hardware problem with ethernet port / cable / rouer / isp.

     

    This might help narrow down.

     

    You can use

    harddrive > applications > utilities > network utility

    to diagnose the situation.

     

    # see whether software is defined correctly

    ping 127.0.0.1

     

    # ping you router address.  Will have to look for address.

     

    You can ping google.com.

    Result:

    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

     

     

    BDAqua suggests in a post.

    You can use OpenDNS for looking up web addresses.

    Put these numbers in Network>TCP/IP>DNS Servers for a try...

     

    208.67.222.222

    208.67.220.220

     

    I think they now pretend you need to join to use, but you don't.

    (Please note that you do not need to a joint Open DNS to use it.)

    While 10.x.x.x and 192.168.x.x are equally valid for intranet addresses.  192.168.x.x is more commonly used by home routers in my experience.

     

     

    blue apple > System Preferences... > Network

    Sometimes I get this screen.  Double click on your connection, in my case built-in Ethernet.

    Picture 1.png

     

    The Router address displays when displaying TCP/IP.

    Picture 2.png

     

    You can also issue the trace router to google.com or any other address.  Will display routers addresses for those routers who want to be known.

    She had no connection to the Network at all but I've didled with the settings including re-installing the router software.  Now, she has an unstable connection to the Internet but neither Safari nor Firefox will load any site even when everything says it's connected.

     

    Could try reseting the router to factory defaults.  It's usually a small button or insert paper clip on the routers.

     

    I know for a fact that FireFox barely works on on 10.4.  FireFox is very down level.  FireFox 3.6.23 works with google.com ( the main search page ).

     

    Don't know what version of Safari, but you need to last released version of safari.

     

    you need to get a more currrent version of a web browser.

  • rccharles Level 5 Level 5 (5,150 points)

    Give Att a call when you are out there.  You need to find a laptop and see if that works with her setup.  Have her contact here neighbors.

     

    Thanks for hanging in, Robert.  I've done her Network address. It shows 10.0.0.1, or 2, or 5, and I've done Renew DHCP Lease and it resets the address, usually one number up.  And the Router IP also shows up in the same format.

     

    I have the 9 digit IP address for the Netgear router, and her current AT&T DNS addresses.  I need her 9 digit IP address, perhaps resetting all of them to that format would do it.

     

    What?

     

    In the first paragraph you said her ip address was 10.0.0.1.  The version 4 tcp/ip number is 32bits. The number is in the form of:

    0-255.0-255.0-255.0-255

     

    There is the hardware MAC address for each ethernet card. It is 48 bits. You can configure a router to filter on the address.  I've never had a need to know what my MAC address is.  MAC is in all upper case.

     

    Picture 3.png

     

    I don't know how to find her 9 digit IP address.  Is there a way to identify her IP address when I can't connect to the Intermet?  All Network Diagnostic lights are green, and the modem lights are green through the Internet light.  There is very little going on with the activity light but some when it's trying to go out to a site.

     

    Why do you think the number is 9 digits?  There are no 9 digit number associated with Internet addressing ( at least not on the top of my memory. I'm not an internet heavy. )   Of course, by chance the number could be 9 digits in the actual possible 0-255.0-255.0-255.0-255

     

     

     

    Anyway, I gave screen shots of in an above post.

    blue apple > System Preferences... > Network screen. 

     

    All the numbers are there.

     

     

    Her mail needs to be reset to the new AT&T settings or I'd try that to see if I could connect there to see if it's just Safari.  Safari is updated and so are all other available Software updates.  I've run Permissions, reset the PRAM (3 times), reinstalled the Router software, rebooted (several times each) the router, the modem, the computer, and I've unplugged connections.

     

     

     

    I'll see if I can search the changes AT&T wants made to email settings and see if I can check the validity of the Internet connection lights that way. Needless to say, clicking on the link in her email message from AT&T re: how to make changes, goes nowhere.

     

    Ping will tell you what is going on.  Mess with one thing at a time.

     

    But ... right now, what I need most is a way to find her 9 digit IP address w/o connecting to the Internet.

     

    See above.  Do not know of a 9 digit number.  & you state her ip address in the first paragragh.
