Ethernet connected, no internet?

2009 27" iMac running 10.8.5, standard specs, new hard drive. I moved a few months ago and started using Ethernet instead of WiFi. When my ISP installed the cable I had issues connecting from the get-go -- network prefs show a stable Ethernet connection and the router is working, but no internet. The first few times this happened I was able to solve it by deleting the systemconfig folder; later it turned out my hard drive was going bad, so I had it replaced and thought the issue was fixed. But this morning I booted up only to find myself without internet once again, and my old trick isn't working this time. Please help!

Diagnostics may narrow down the problem ...
Open System Preferences > Network
Select your connection on the left then click: Assist Me
Then click Diagnostics
If any of the buttons are red, click Continue.

Ethernet connection to Internet not working

I have a mac mini (pre wireless) connected to a siemens gigaset se587 wlan DSL router via Ethernet cable. This worked fine when I set it up a couple of weeks ago. Now the mac mini has stopped connecting to the Internet. The router is working: I can still connect to Internet wirelessly on my iPhone and can still run airtunes on an Airport express from the iPhone remote app.
My ISP (tiscali) don't support mac and have been useless. Apple support also can't work it out.
I've reset countless times and tried setting up a new connection and the mac can recognize the router it just won't open any web pages!
Please help - I'm tearing my hair out!

This could be a DNS server issue.
Following the suggestion in this post (thanks AndyO!) to enter an IP number directly would give us more info:

If it is a DNS server issue, then switching to DNS server like OpenDNS might help resolve it:

Airport Express does not allow ethernet connection to internet

I use my Airport Express to stream music to my speakers from iTunes, but I find that I cannot access the Internet via the ethernet modem connection. What is the deal?

Hello Stonegroove. Welcome to the Apple Discussions!
In order to use the Ethernet port on the AirPort Express Base Station (AX) to access the Internet, the AX would have to be configured as part of a Wireless Distribution System (WDS).

Resetting Time Capsule - network is OK, but no longer connects to internet

I've set up my TC in the past and it's worked fine, but periodic printer or router updates have caused problems and I think I need to completely reset it.
My setup is an ISP-suppled Orange Livebox Mini router connecting to the internet, an iMac plugged in by ethernet (connects to internet OK) and my TC connected to this router by ethernet. My MacBook Pro then connects wirelessly to the TC network. This setup means I don't need to have two wireless networks, I can disable the Livebox router's wireless network and use only the Time Capsule wireless. However, that's not working. I can create a wireless network with my MacBook Pro but the TC is unable to get an internet connection despite being connected by ethernet to the router. I think I need a total reset but even when I do a manual reset by sticking a pin in the tiny button on the back of the TC, when Airport Utility finds the TC to recreate a wireless network, I find the old settings. I feel this is, or should be, simple stuff as I managed to set it up before, but this time it's just not happening. For a long time I thought this was just a problem with wireless settings on my Lexmark printer and waited for the Apple/Lexmark updates to come through, but now I think my TC settings need to be flushed out. One thing that looks odd to me is the IP address on the TC. It's 169.xxx.xxx.xxx, I thought it should be nearer the range specified by the Livebox router, something more like 192.168.x.x
thanks.

Oh joy and happiness, I solved it myself, and I owe it to the community to give some details for the benefit of anyone with the same problem searching on terms like Orange Livebox Mini.
I solved it by racking my brains till inspiration came - that it was a very very well hidden setting on the router itself that was the problem, nothing to do with Time Capsule. I had called Orange to fix this before, but had forgotten that this little setting needs changing from its default every time you reset the router.
When you have to reset your Orange Livebox router, they more than likely won't ask about your entire setup, they will get one of your computers working by connecting it by ethernet to the primary ethernet port, numbered '1' on the back and with a red stripe next to it. But there are two, number 2 has a yellow coloured stripe and if your main computer, in my case the (desktop) iMac right next to the router goes into ethernet port 1, you will want to connect your Time Capsule into the second, yellow ethernet port. However, that port is not set to work automatically for anything to connect to, it's set up for digital tv. You need to go into your Orange admin page for the router, found by going to 192.168.1.1 on your browser and logging in (remember 'admin' is the magic and default password to get you in. If you have to do a manual reset because you changed and forgot your password, the magic word gets you back in). Once logged in, select 'services' in the menu on the left, then 'digital tv' and then select the 'disable' button. I know, you'd never have found it and never have guessed that's what you need to do to open up the second ethernet, but you now have two ethernet ports into the router and your TC goes into the second work.
Also wanted to say that my TC has actually been flawless in its performance. Not always easy for simpletons like me to set up, but the hardware has always worked. Printer updates and, I think, Apple OS updates remain a problem as they can throw the printer off, but I must remember to keep my nerve - TC is basically right on, it's just the various different ways to get at it - Network Diagnostics, Airport Utility that confuse me.

Airport Extreme set-up - Ethernet connection ok but wifi connection doesn't see the internet

I'm trying to set-up a new (5th Gen) Airport Extreme 802.11n Wi-Fi to replace an existing TRENDnet router.
It's connected to a Motorola cable modem with Optimum internet service.
When I hard wire my laptop (Windows) through ethernet I get internet access. However when I try to connect via wi-fi on the laptop the Airport Utility displays 2 errors: Internet not available and No DNS server.
When I try to connect my ipad, when I select the Wi-fi network I see the network and it tries to connect but continues to cycle, with the wi-fi icon appearing in the top line then disappearing before returning. In the Airport utility on the iPad I see the same issues listed as on the laptop.
In the airport utility under the internet connection, "Connect using" is set to "ethernet" and "connection sharing" is set to "Off(Bridge mode)"
Appreciate any help.
thanks

I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Power-up the modem; wait at least 10-15 minutes.
Power-up the base station; wait at least 5-10 minutes.
Power-up your computer(s).
In this basic configuration, computers connected to the base station, either by wire or wireless (as appropriate for the base station type), should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options.

Time Capsule won't connect to internet, says ethernet isn't connected

I have the 2013 Time Capsule + Airport. I tried setting it up as normal, connecting the ethernet cord to the WAN port and to my charter modem. During setup it sticks on the screen saying that the ethernet cord isn't connected. I have done everything trying to fix it. I've reset the modem, the time capsule, tried to redo the set up, tried skipping the setup and power cycling the sytem. I've unplugged the modem for an hour, turned off wireless to all laptops, unplugged the time capsule, and then powered the modem on and let it run for over half an hour. Then I started the time capsule, let it run for half an hour. Tried to see if it could connect to the internet, nothing. It keeps flashing amber. The ethernet cord works, as does the modem, as I can still use my old Belkin router that I was hoping to replace with this time capsule. It's just the time capsule. I'm losing my mind trying to get this thing to work. My modem doesn't have a reset button, so that won't do it. If there are any terminal commands that might fix it I'm open to trying that as well. Anything, at all, would be helpful, because I have no idea why this thing won't work.

Is your charter modem also a router?
When you plug the ethernet cord in, does the ethernet connectivity light come on.. both on the modem and on the TC port.. ?
Try setting up the TC in total isolation.
Reset it to factory.. the full method.. ie power off the TC.. Hold in reset.. power on the TC, without releasing reset. Keep holding in reset for 5-10 sec until the main LED goes to rapid flash mode.. then release it.
Do not plug between the TC and modem.. but you can run the cable to the computer..
Do a full manual setup.. this is a bit tricky.
After a full reset the TC will come backup in router mode with an IP address of 10.0.1.1 and the ethernet plugged into the computer should show 10.0.1.2
Make sure ipv6 is set to link-local.. it is important.
Now open the airport utility.
Go to configure other.
Type in the IP address. (Password is not needed after a reset but if you do it is public)
Now you will get the manual setup screen.
Go to the base station page and give your TC a simple name.. eg TCGen5
These are my setup which is older one.
Go to the internet tab and choose dhcp.
No picture required I hope.
Go to the wireless page and setup wireless. In your case TCGen5 is also a good wireless name.
Or you can give separate names to the two bands. TC24ghz for 2.4ghz
And TC5ghz for the 5ghz band.
Now finally the most important screen.. Network.
Is the modem a pure modem.. no router.. pick the top option.. DHCP and NAT.
Is the modem a router as well, pick the bottom option. Off (Bridge Mode).
Then do update of the TC..
Plug it into the Modem.. WAN port of the TC.. make sure the ethernet connectivity led come on..
Open the Airport utility and see if it has got an IP on Internet tab.. no luck.. take the TC back to apple for testing. Faulty out of the box is happening.

How do I use my ethernet connection for printing on my LAN and use my Wifi on a different router and ISP to connect to the internet?

I'm in a small office, and I have to use my ethernet connection to connect to the networked copier to be able to print, but connection to which I hooked my Time Capsule is literally 20x faster when connecting to the internet.
How can I tell the computer to use the ethernet connection to print, while everything else should go through wifi?
I have been manually going back and forth changing the order in Network Preferences between ethernet and Wifi, but I'm know there must be an easier way. Thanks for your help!

A packet going to Apple is not local. It is going to 17.149.160.49 -- So it is sent to the topmost working connection to be Routed and sent to the Internet.
A packet going to a local computer or other device that is on the same subnet (has an IP address very close to the topmost IP Address of your computer) gets sent out that port as well, but is sent directly to that computer on the local subnet, since no Routing [changing of Addresses} is needed.
A packet going to a local computer or Printer or Network Attached Storage device that is not on the topmost subnet, but is on a secondary subnet such as the second network connection would be sent directly to that computer, since no Routing is needed.
I do not understand why two Routers have the same IP Address if they are not cross-connected. That makes everything very difficult when it should be simple.

Airport Network status says Internet failed and I can not connect wirelessly. Ethernet connection works fine. Why can't I connect?

A few days ago, my Airport Express wireless connection stopped working. The network status lights for Internet and Servers are RED and indicate failure. My Ethernet connection works fine. Any idea what my problem is?
Thanks,
LivingSuccess

You could try a Safe Boot - restart holding down the shift key until the grey progress bar appears. When it's booted restart as normal from the Apple menu.
If that doesn't help you could try an SMC reset:
SMC Reset
Shut down the computer.
Unplug the computer’s power cord and disconnect peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.

My wi-fi worked fine on Airport Express two days ago. Now the light is green, but I can't get the Internet on my satellite connection. I've checked Network Preferences, Aiport Express menu, and the satellite tech support. The Ethernet connection works.

My wi-fi connection from my iPad via the Airport Express Base Station on my home computer worked just fine until yesterday morning. I have a Macintosh G5 with a satellite connection. I could not get an Internet connection. After using the Network Preferences and Aiport Express applications several times, then unplugging and replugging in the computer, satellite modem and Airport Express module, checking the satellite dish for any obstructions, and so on, the computer still wouldn't connect to the Internet. (The green light was on in the Airport Express module.) I called the satellite company technical support division last night. The tech couldn't find any problem with the satellite connection. When I plugged the satellite modem cord directly into the Ethernet outlet on my computer, I could pick up the Internet.
Today, the Airport Express module still has a green light but still doesn't connect to the Internet. The only thing I can think of is that lights went out for about 15 minutes yesterday morning. All of my electronics, except the Aiport Express Base Station, are on surge protectors. Why would the Airport Express module still have a green light if it was damaged by the electrical outage?
I bought the module in 2009. I have never had problems with Apple equipment before this. Is this base station fixable?
I would appreciate your suggestions.

Hello everyone. I too have experienced the same problem Mary described starting on the same day she mentioned January 12. I have a G5 iMac, a G5 mini-mac, and a G4 laptop. They were all working fine but all have mostly the same problem now in that the G4 does not connect at all and the G5s connect once in a while after restarts but do not maintain the connection. In my case there was no power interruption. In fact, the G4 laptop was not even connected to the home power connection. My iPad2 and iPhone 4s wireless work fine and a wireless PC and Android tablet work fine as well. The G5 and G4 work fine on an ethernet connection. ISP tech support (AT&T u-Verse) was very generous with their time in trying to solve my problem although it was established early on that their connection and equipment was working fine and that the problem was with my computers. They walked me through a manual reset of all the particulars on IP addresses etc. so the problem was not related to that either. In the end ISP tech support concluded that the problem must lie with the Airport driver. For some reason it changes the IP addresses to an incorrect address so it cannot connect. Indeed when I tried the diagnostics on the G4 I got a window Pop-up that said an application had reset my settings. (In retrospect I seem to recall that I may have gotten that same message early on with the G5s but at that time I did not think much about it and went about trying to reset the settings but that process never concluded well) I think that the problem may be that there must have been an update of the Airport software that was not backward compatible with the G5 and older Macs. I mention all this for two reasons. First, perhaps someone out there who knows better than I do how to bring this to Apple's attention and perhaps they will address this. Second, I would be curious to know whether there is anyway one can return a configuration on Macs to some earlier time period (as you can on PCs) when everything worked and then leave it that way foregoing any subseqent upgrades or any subsequent apps?

I lost the lan ethernet connection of an older windows 7 pc to my 3 Terabyte router when adding a new local printer to the pc. How do i set this up again so the PC is recognized and can get to the internet again through the time capsule?

I recently added a new printer to a 2005 vintage PC that is running windows 7. It used to go through a router in my wifes upstairs office to the time capsule by wired ethernet (cat5) but when I added her new local printer thought I would network it, big mistaked, lost all my ethernet connection and she cannot get to the internet. Wireless not an option. How do i set up again the ethernet connection and i will only USB the printer locally this time for the windows pc?
Tried windows diagnostics, and besides telling me to reset everything and turn router off and on etc. I am in an endless loop.
Other Mac products are not impacted by this issue.

I see no direct connection.. a printer and the computer setup for internet are not related.
But it sounds like the router in the wife's office is now in the wrong mode..
If you have an existing main router replace the second router for a switch .. that is the easy way.
Otherwise you need to bridge the router if it has that option.. most do not. Or use wan bypass.. where you turn off the dhcp server in the router and fix its ip to match the range of the main router.. this is the hassle of using router as a switch.
BUT I am making a huge number of assumptions.
What I need is the full network layout.. a quick picture would help.
I need main modem.. main router.. (maybe same box or different).. make model and current IP address and how dhcp is setup.
I need secondary router.. if that is what it is, IP and settings.
I want the printer type and model. How it is connected.
BTW I much prefer to see a network printer plugged into the network rather than usb.. it is only a matter of sorting the IP settings and driver pointing to the network rather than local.
Or you should think of it as a broken washing machine and call the technician.. who could fix the whole lot in an hour.

My Mac Mini is not connecting to internet through the ethernet

Had an issue with my internet provider, which was resolved after a month.....at this point my internet is not connecting through the ethernet cable (no router is being used, from modem directly to mini mac).....ERROR:YOU ARE NOT CONNECTED TO THE INTERNET
When checking on the Network Preferences it shows the ethernet connected but it does not show the Router IP nor the DNS Server.
If i run diagnostics ...ethernet is green, network settings is yellow and the the rest is red (how do i fix this network settings)
If i try to run the NETWORK SETUP ASSISTANT and tried using
IP 192.168.1.33
Subnet mask 255.255.255.0
Router 192.168.1.1 (even though i don't use a router, but this was the last set up i saw working)
DN S Server 192.168.1.1
It takes for ever as configuring but does not do anything
Please advise what am i doing wrong or missing here......
I've read people selling their equipment, taking it back, using their warranty.....i don't think it is something the serious but still i'm not going anywhere with my troubleshooting
HELP!!!!

Deleted the previous ethernet and added a new one (System Preferences/Network).....did not work
At this point in diagnostics it show Ethernet and ISP in green, Network Settings in yellow leaving Internet and Server in red.
It's a bit frustrating because it did work fine until a week a go and since then have tried several things and....nothing
Not interested in buying a router because of this issue......any other work around?

How to connect ipad to internet over Windows box on ethernet connection

Due to available infrastructure, I would like to use internet (if it is possible) on my iPad over Windows box connected to internet.
Is there any solution?
THX Duke

Connect Ethernet cable to Airport Express to generate Wi-Fi for iPad.

Automatic switch over from wired ethernet connection to wireless (different internet networks)

I have an Imac connect to 2 different internet service providers 1) a wired connection via ethernet giving a 10mbps download speed but unfortunatley the signal can randomly drop for a period of seconds, minutes or even hours, which I then have to manually disable the ethernet connection and switch to the wireless provider, a tedious task..
I was wondering if there is a way whereby i can set the ethernet conection to automically switch to the wireless connection during the periods explained above?
Thanks for your assictance.
David

OK, thanks for the update.
Let's try to figure out which device is actually providing the PPPoE service. It will be either your modem or the AirPort Extreme router.
Normally, the PPPoE connection service is established on the modem by using a web page for configuration. If you have setup the PPPoE service this way, then the AirPort Extreme must be set to Connect Using -- Ethernet.
Please use your computer to check some settings as follows:
Macintosh HD > Applications > Utilities > AirPort Utility
Click Manual Setup > Click the Internet icon
Look for the Connect Using setting near the top of the page
It will be set to either "Ethernet" or "PPPoE"
Which setting do you see?
Note...if you are still using OS 10.4.x as you indicate, this may not be the path to find the setup information. It may be in an older application on your computer called AirPort Admin Utility.
Sorry, I can't remember much about 10.4.x, so you may need to look around a bit on your computer.

Airport Extreme has ethernet connection but no internet connection

I am having an airport extreme connectivity issue that has yet to be resolved. For me, the cable modem (a Motorola Surfboard) recognizes the airport extreme (I have the round white saucer one) but the airport extreme, despite giving me an 'ethernet' connection (that also shows up as full signal strength in the menu bar), cannot connect to the internet, no matter what I do.
Seems the airport extreme is not recognizing/picking up the ip address of my computers.
The airport base station is recognized by airport utility, has an ID and I can name it as well as create a network, but no matter what I do and despite being told that I am connected to the internet via ethernet, there is no connection to the internet.
I have a dual G5 desktop hooked up directly to the cable modem and am trying to wirelessly connect a new macbook pro intel core dual.
Each computer can access the internet when directly hooked up to the cable modem, but neither can access the internet wirelessly.. so it's not the computers, nor is is the cable modem. I called Time Warner, all is fine with that connection.
Both my ethernet cables work (checked them both). So it must be the airport extreme.
I was on the phone with apple tech support for 5 hours yesterday!!! They made me run through all the things I did myself. From trying to reconfigure and rename the airport to completely resetting the airport. None of this worked.
And right now I'm on hold for a multi-media product specialist with apple tech support.
But they didn't do a thing for me yesterday so I'm hoping someone on here may know what to do.
I think I need a new airport extreme. Anyone???

Hello Laura, Jim, Richard...
Now my internet connexion work on my AEBS (Airport Extreme Base Station)... It seems that (for me) DHCP was the problem...
DHCP server (10.0.1.x) activated on the AEBS conflict with DHCP server (192.168.1.x) activated on the modem.
Before the AEBS 5.7 update (i made yesterday) this configuration with two DHCP servers with different IP addresses worked well... but not now...!
So, i disabled the Modem DHCP server. I rebooted the modem and the AEBS and success, my internet connexion worked again...
I used manual setup with fixed IP, submask, DNS to connect the AEBS to the modem...
I hope this could help you, Laura and Jim...
Sorry for mistakes, i'm french mac user

Connected to internet via ethernet but server not responding

I have browsed some threads on this topic but none gave me an answer, and my set up is not quite the same as those that I've read. I don't want to hijack another thread and confuse the readers. I would be very grateful for help on this issue.
I have connected a G3 imac to a G5 imac with ethernet cable and both are configured for file sharing following the instrauctions on this help site. Both machines communicate and file sharing is okay.
Now I want to share the dial-up internet connection of the G3 with G5 over this ethernet connection. I have configured both machines following instructions on this site. At the moment file and web sharing is enabled on both machines.
In sharing preferences/internet internet sharing is turned on on the host (the one connected to the internet)
In sharing/firewall personal web-sharing is checked on both machines
In built-in-ethernet/TCP/IP config IPv4 is off on both, although i have tried it with IPv4 set to using DHCP on the host, and then on both
No proxies are set
I have tried it with Appletalk both on and off on both machines
In network status internal modem is at the top of the list on the host and ethernet is at the top on the guest and both say that they are connected to the internet. The ethernet appears as connected to the internet with green light even when the host computer is not connected to the internet.
Yesterday I was able to browse using IE in windows XP running on virtual PC on the guest (G5) but this is the only time it's worked and I don't know what i did for that to happen. I only wanted to run a software activation on the G5 but the message unable to establish a connection appears.
I followed the help in virtual PC to share the Macs internet connection with windows, but havn't been able to connect to internet using the browsers on the OS X system. Tried altering browser preferences as well with no joy.
Everything works fine on the G3
I don't know where to go next.
imac G5 Mac OS X (10.4.3)
