G4 MDD won't connect to internet
Greetings! I hope someone can help! I have a G4 MDD 1.25 GHz DP running 10.5.8. Earlier tonight, it stopped connecting to the internet for no reason I could discern. I had used it on the internet (both with Safari and Firefox) with no issues all day. The machine is connected via ethernet, through a switch to a wired/wireless router. I had put it to sleep, and reawakened it maybe 15-20 minutes later, and when I did so, found that it would not load web pages, etc. Safari reported you are not connected to the internet. The network panel under System Preferences reported that the machine was connected to ethernet, but had a self-assigned IP address. Network Diagnostics told me I was not connected to the internet, and that it could not repair the connection. I tried restarting the machine, but no joy. I tried re-booting both the switch and the router, with no joy there either. The thing is, that 2 other machines (a BW G3, a windows desktop) are networked via the same switch to the same router, and a windows laptop wirelessly to the same router, and throughout all of this they have had no issues connecting to the internet. I tried swapping out ethernet cables, and connecting to different ports of the switch, but the results were the same - other machines connect to the internet fine, the MDD will not. Thinking that something may have been corrupted, I tried re-starting the MDD with a firewire drive containing a clone I had made yesterday (when there were no issues) of the startup drive. Same result as before - no internet connection. I have noticed since then, that, when I restart the machine, for the first 3-5 minutes the System Preferences network panel will report a self-assigned IP address. Then, after a few minutes, it will report a real IP address and the address of the router. Furthermore, the BW G3 will show up under the Shared heading on the left hand side of an open hard drive window. But if I open a web browser, it spins forever and reports (Firefox) that it could not find the server, or (Safari) that I am not connected to the intenet. It seems clear to me that the problem is not the router or switch, because other machines connected to the same router and/or switch have no problem connecting to the internet. Furthermore, it doesn't seem to be an electronic problem in the MDD, because it does report that it is connected to the ethernet, and eventually gets a valid IP address, and it sees the other mac on the network. So, any ideas about what is wrong with it, and what I can do to fix it? I will be very grateful for your wisdom and suggestions! Thanks, Fr.

Was there any lightning? If there was the onboard Ethernet may be shot.

Re: G4 MDD won't connect to internet
Alex: No, no lightning, or any other catastrophe. Besides, as I mentioned in my original post, the machine is reporting a connection to the ethernet, and is seeing the network at least so far as to see the BW G3 under the sharing heading. Also, now there is no delay in seeing the ethernet connection and reporting a valid IP address. So, the machine connects to the network, gets a valid IP address, sees the other Mac on the network, but won't connect to the internet. Any other ideas?

Re: G4 MDD won't connect to internet
Alex and Ken: I did check all the physical connections, and they were fine. And again, as I mentioned in my original post, the machine reports being connected to ethernet, and gets a valid IP address, and sees the other Mac on the network. Also, the appropriate link and activity lights come on on the switch when the Mac is started. The mac is getting the valid IP from the router. If it is a network config problem, then why do the other machines (BW G3, windows boxen) connected to the same router via the same switch have no problem connecting? And how would I fix this?

And again, as I mentioned in my original post, the machine reports being connected to ethernet, and gets a valid IP address, and sees the other Mac on the network. Getting a valid IP is not an indicator of a good internet connection. It is merly a hint that the DHCP server works. A DHCP server distributes IP addresses for all the computers in the network that connect to it. Having a DHCP server is one of the duties of the router. A switch works on the hardware level of the IP protocol and as such it doesn’t make a difference if the computers are connected one on earch ethernet port of the route or through a switch. Also, the appropriate link and activity lights come on on the switch when the Mac is started. The mac is getting the valid IP from the router. So the ethernet part works. You get an IP. All should be fine, right? If it is a network config problem, then why do the other machines (BW G3, windows boxen) connected to the same router via the same switch have no problem connecting? And how would I fix this? Well, my router has the “feature” to “[allow|deny] internet access for new devices”. This would result in a similar behavier as you describe: the machines that are already known by the router (your other machines, BW G3 and Windows PCs) are allowed internet access, whereas the new device, which happens to be your new Mac, is not. As I’m saying, this is only one possibility. I assume we are talking IPv4 here? Other routers allow or disallow internet access for specific IP ranges, i.e. 192.168.0.1 though 192.168.0.50 are allowed WAN, whereas 192.168.0.51 through 192.168.0.255 are allowed LAN only. (WAN = wide area network, i.e. everything external to the internal network, i.e. the internet) (LAN = local area netork, i.e. your internel network, where you can “see” the other computers) Note that some routers use different IP addresses, like 10.0.0.138. You should see the setup of you router if you type its IP address in a browser (like Safari or Internet Explorer): http://10.0.0.138 http://192.168.0.0 Though it could be also a configuration problem on the Mac OS X side of you new Mac, I think that the very likely explanation is a network (i.e. router) configuration problem. In order to help: 1.) What IP addresses do your computers get from the router (through DHCP)? 2.) Which router do you use? 3.) What is the IP of the router and the IP ranges for the devices (via DHCP)? 4.) IPv4 or IPv6? 5.) Which Mac OS X is on the new Mac? Is it a fresh installation?

You may need to delete your system network configuration preferences file. If you can get an IP address, and see local systems, then the issue is either your system cannot find the gateway address to access IP addresses beyond the LAN or the network mask is wrong. Since both of those are sent by the DHCP server along with your IP address, either your DHCP server is messed up (the router) or the network configuration is wrong. Check the settings against a working mac. Also do the other, working systems function after a reboot? or if you select 'Renew LEase' in the TCP/IP settings in the Network control panel? DHCP is only important at the time an address is handed out; typical home routers give out addresse setting s with very long lease times, so the mac doesn't actually ask for a new address that often. -- Bruce Johnson Wherever you go, there you are B.

Re: G4 MDD won't connect to internet
Bruce, Mac User, and Ken: Thanks for all your help and suggestions! After posting my last reply, I shut down the MDD and took a nap for a couple of hours (I was up till 4:00 AM). When I started it up, it took a bit longer than usual, and there was a lot of disk activity. So I let it go, and even after it had, to all appearances, completed start-up, there was still a lot of disk activity, really churning. It was clear that the machine was doing something, although I had not opened any applications. So I let it do its thing, which took about 10 minutes. When the machine had stopped al the disk churning, I checked the network panel in System Preferences, which reported a valid IP address. I fired up Safari, and, halleluia, it loaded my home page. Browsers are surfing the web just fine now. I had done/changed NOTHING. It seems that OS X fixed the problem all on its own. I just wish it hadn't cost me a few hours of sleep in the meantime. Any ideas on what the OS might have done, or what the problem may have been? Thanks again!

Re: G4 MDD won't connect to internet
After doing everything that John has suggested (even pull oput the ethernet card and clean it and reseat it), I would go to System Pref then click on Network and change the settings to AirPort only (shut everything else off)... I had an iBook Clamshell do this to me many of times, once I changed it to AirPort only it never did it again!!! I think something happens when it goes to sleep that causes it (it must be confused when it wakes and doesn't remember where it was before it went to sleep LOL) -Original Message- From: John Carmonne carmo...@aol.com Sent: Jun 16, 2012 8:43 AM To: g3-5-list@googlegroups.com Subject: Re: G4 MDD won't connect to internet On Jun 16, 2012, at 5:22 AM, Alex Sciortino wrote: Was there any lightning?
