IMac PPC :: Why Can't Connect To The Internet
Apr 30, 2012
After more than 5 years of having to constantly reboot my router because of lost connections to the Internet, I thought it would be time for a change. So I purchased a new Netgear router that works great with my mobile devices, including a PC notebook I have on my home network. (I should note that while all the other devices on my home network would lose their connection, the iMac somehow never did.)
However, when it came time to connect my iMac G4 I ran into some trouble. The iMac recognizes the new router and the WiFi signal strength is perfect, but I was unable to connect to the Internet. I opened the Network utility in Preferences to try to check the settings, and the following error message appeared:
<<Your network settings have been changed by another application.>>
What happens is, even though I click OK to clear the message, it keeps on reappearing on an endless loop; the only way out is to Force Quit the Network utility. Although this problem occurred with my older router, I was still able to connect to the Web; now I can't.
Info:
iMac (Flat Panel 2003), Mac OS X (10.4.11), Airport card installed.

I've got a couple of week old imac and I'm having huge internet issues. Pages don't load fully and sometimes don't load at all. No problems on my macbook.

My mother-in-law has an old Blueberry iMac which works ok except it won't connect to the internet/LAN. It is the computer, because the cable that used to connect the iMac to the internet is currently connected to a different computer and it works perfectly. The iMac runs Mac OSX 10.3.9. Has something died inside the iMac?

Daughters imac desktop upstairs has always had a weak connection (takes a few times to get started) but has been used this way for 3 years.
Of late she cannot get connected unless she brings it down to next to the router, and often dosen't work unless she plugs in the ethernet cable.

My wireless connection from my iMac to my AT&T router was working fine. Recently my 27" iMac (using Snow Leopard 10.6.8) cannot connect to the internet.The IP automatically getting assigned (using DHCP) is 169.254.21.210.The AT&T router is also connected to a Windows 7 PC and that is connecting to the internet without an issue. The IP that should be getting asigned is: 192.168.I am typing this "issue" using my daughters Mac Book Pro which is next to the iMac that has the connection issue. Obviously the Mac Book Pro is working fine. Shouldn't be a location issue. Also have used 2 other Mac Book Pros successfully as well as a Windows laptop from work. All work fine. Just the iMac is not working. Have setup the network connection again to no avail. I have used the Network "Assist me" option with no success.I also connected an Airport Extreme Base Station to the AT&T router with hopes of connecting.The iMac sees the Base Station (and also the AT&T router) but fails to connect to my ISP.Does anone have some experience in this area? Why is the Mac assigning a 169.254... ip address?

How can I setup my iMac so I can connect to it's hard drive, files, etc over the internet? I'd like to connect to my iMac at home from my macbook while not at home. I'm familiar with connecting to my iMac from the "shared" section in the finder while i'm at home and in my home DSL network, but how would this work if I'm outside of my home DSL network?

My father in law had a power failure at the house, and since then, he cannot connect to the internet via DSL Modem connected via ethernet cable. Being that he is 1000 miles away, I am trying to diagnose via phone. System Info: Imac 17", purchased new around 2006- Intel chip, running Tiger OS
Symptoms:
- Cannot connect via ethernet
- When searching system profiler, "Built-in Ethernet" shows up, but no MAC address
- In Network settings, he can see the various connection ports, but cannot check the box on "Built-in Ethernet" to turn the port on... won't let him.
- Wireless is not an option, I don't want to be 24/7 tech support
Diagnosis? I am thinking that the power surge may have fried the ethernet port on the motherboard.
Repair Solution: Planning on picking up the Apple USB Ethernet adapter. I know it doesn't have the correct drivers to run on Tiger, but found a driver online that claims it allows use of the usb adapter on Panther on up.
Questions - Does this sound like a fried ethernet port? Any other easy diagnostic tests I can do? Does the USB adapter sounds like a decent solution?

I've tried resetting the router and various other things that I found on the internet. I know its not a router problem as I am using my MBP to post this discussion. It won't even connect to the router's internap page.

One fine day, my iMac running Mavericks 10.9.2 has stopped connecting to internet over WiFi. it is self assigning an IP to itself and refuses to do a DHCP handshake with my router. My other wifi devices can connect to this network without any issues. So us the same iMac when it runs Windows 8.1 on the boot camp partition. I have tried the following fixes, but to no avail:
1. Delete the location
2. Delete networks
3. Reset DHCP
4. Restore Mac to a previous restore point where it used to connect to internet without any issues.

i can't connect to the internet via my ethernet cable, but this is a weird case. What's weird about it is that all my settings are O.K. (appletalk on and set to ethernet, tcp/ip set to ethernet, dhcp) and my iMac is recieving a 192 address, but it still can't connect to the internet. The dhcp settings are correct, because they are the same settings used on all my other devices (at least those that use internet anyway), and they all connect to the internet just fine. Whether via an ethernet cable, or Wi-Fi.
Info:
iMac, Mac OS 9.2.x

I have recently had to stop using my wireless router and connect directly from my modem to the WAN port on my computer. However, I can only achieve an internet connection when I direct connect into my PowerBook G4. When I try to connect into my iMac, I get nothing.

I have a macbook a little over a year old. It's my first mac and I love it. Yesterday though it started acting really weird. I first noticed that it was really, really hot and the fan was running. I turned it off and back on and here's what I found out:
Applications are being deleted from macbook. ITunes, IPhoto, iChat have clear question marks over icon. There are 8-10 blank spaces in the Applications folder where applications have been deleted. However, data is still there (ex. pictures still there, but no iPhoto).
Internet= Says I have internet but wont connect.
Cannot open " System Preferences" or "Internet Preferences".
If connected to home computer will connect to internet and allowed to open internet preferences but still no system preferences.
If shut down....takes a while to come back on and starts up 2-3 times.
Also "Preview" is gone. Now " ColorSync Utility" opens.
Is this my hard drive dying? I'm tech challenged, so any help would be greatly appreciated.

I'm running OSX 10.5.8 on a Macbook Pro, and today I've been unable to connect to the internet via ethernet or wi-fi, unless I'm in safe mode. Then everything seems to work as it should, which makes me believe that this is a software issue rather than a hardware problem. I've tried making a new account with administrator priveleges, but that doesn't solve my issue. Does anyone have any advice on how I can connect to the internet under my normal user account, rather than in safe mode? I should note that I won't be able to get my hands on my repair CD or perform a clean install of OSX because that stuff is at home, and I'm in college. Also, I'm at a university and don't have a router. I just use the campus-wide wi-fi. Finally, my roommate has no problem accessing the internet in our room via ethernet or wi-fi, but I do. Thanks for the help everyone.

currently I connect to the internet by doing this: Go to System Preferences / Network. Then I select my internet provider name on the left pane and finally click on the Connect button. That's all. This internet profile has a PPoE service name, an account name and a password. My internet connection uses a cable DLink router (it's not wireless).
Question:
1) Does the password I mentioned above mean that my neighbors can't access my internet, or are they able to do that and, in this case, I need to set another password somewhere else?
2) If I need another password, how and where do I set it,

I have a blackbook (intel core 2 duo) and I can connect to my landlord's wireless network (they have a netgear wgt624) but I can't actually use the web (Safari or Firefox will just "think"). I've tested the diagnostics and it confirms that my mac can connect to the network, but it cannot connect to the internet. The network uses WPA personal and it has a 19-aphanumeric passphrase.
*Also - would it be possible for me to extend the wireless range (and make it possible to browse the web) if I used my own 2wire wireless modem to connect to the netgear wgt624?

I am a Mac novice and just got an old Mac G4 w/ 10.2 on it. It has no wi-fi hardware. I want to connect it to my US Robotics 8054 wi-fi router, to which my XBOX360 and Windows XP PC are already successfully connected (all with wires... not using the wi-fi feature of the router).
I've connected it and Safari can't get to the WWW. On the Network control panel it says "Location = Automatic, Show = Built-in Ethernet, Configure = Using DHCP."
What else should I be looking for to get this bad boy up and running?

I don't understand this. We have three profiles. On two of them, we can connect to the Internet with Safari. However, we cannot on the third. We've tried both Safari and Firefox. It says I cannot connect to the server. What do I need to do to fix this?

My Dad is currently unable to connect to the Internet with his Mac.
He's using Mac OS X Version 10.4.11. It connected fine this morning but he's been unable to connect this afternoon or this evening. A message keeps popping up saying: "Could not find a PPPoE server". I've tried running through the wizard for setting up the connection but it doesn't seem to work.
I've been using my PC online all day with no problems.

Yesterday, I attempted to wirelessly connect to the internet and I am getting "your computer is being managed by The Gaines Family6 (that's my host computer)". I thought it was my router so I unhooked everything and started over and still the same thing.

I've been using Safari for awhile and it's been working fine. However, the Macheist chat stopped loading the past few days, and I know it's just me, because other people can connect. So I thought I would download Firefox to see if that would work, but when I type in a webpage in Firefox, it would just give me a blank white page. So I thought it was just a bad preference file, so I deleted it, but Firefox did the same thing. So I downloaded Firefox 2, and the same thing happened. Now I was a little freaked out, as you can imagine. Then I downloaded Camino, and the same the happened-a blank white screen! Only Safari can connect to the web.

Randomly my nice old G4 PowerMac, running 10.4 stopped connecting to the internet. Checking the Ethernet settings, it isn't seeing any information.
My cable modem and router are both fine. The router is wireless, and computers receiving the wireless signal work fine. I hooked the modem up directly to the Mac, and it still wouldn't see it.

I just moved into a new apartment, set up new internet and router, but I have trouble accessing a lot of websites, like [URL]. All my friends are using PCs, and I'm the only one on Mac. None of their computers have trouble going to the same sites, but I'm stuck watching a blank screen.
I researched around, but I cannot find a solution to this. I've tried pinging websites, running the command line to flush the DNS cache, but nothing has worked. Is there some sort of system preference I have to set on my Mac, such as lowering security features, to access the sites I use the most?

Today I happened to come across an old blue and white Power Mac G3 at a local thrift store, and I'm wondering how to connect it to the Internet. It has what looks like an Ethernet port on the back, but the cable won't fit. What do I need to connect it?

Anyways, I have a MBP 13" (new model) and I have a PS3.
Previously, I used a Windows7 laptop and I used to connect my PS3 to internet using an ethernet cable, while my laptop was connected to internet through a 3G USB modem. Now I need to connect my PS3 to net using the 3G USB modem, except I'm using a MBP. It doesn't matter if it's using an ethernet cable or making a WiFi connection between my MBP and PS3.
