Failed internet and server

Hello,
My new imac is giving green lights for Ethernet, Network settings and ISP but red for internet and server. I have another mac next to it which is fine through the same connection and the phone and ipad are fine on the wireless from the same router so its a problem specific to the mac. I have booted the mac from a bootable hard drive of a clone of the previous mac and it connects fine with all green lights so its something to do with the mac settings. I have compared the two macs and the settings are almost identical, IP addresses not clashing but DNS server is the same.
I am tearing my hair out and am thinking of a factory reset but it has a fusion drive and Im not sure how to go about that. It also says on the apple site that if you are going to do a reset make sure you are connected to the internet... but that my problem in the first place!
I really hope someone can help.
Many Thanks.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Every now and then (every 15 minutes-half an hour or so), my internet fails. It says in the Diagnostics that the internet and server have failed. Happens on my sister's mac as well. Is this our modem?

Hi Patrick,
I'm starting to think it's either an AirPort card issue or something to do with the Mac OS. I have stopped using wireless as much as possible in my home (have wired up several new Ethernet outlets), and it sure is nice having Internet run at the speed it's supposed to all the time, and with no drops. Might be something to consider.
In the meantime:
Open System Preferences > Network > select AirPort > click on Advanced > TCP/IP > Configure IPv6 > Off > OK > Apply > Turn AirPort Off > Turn AirPort On
Open System Preferences > Network > select Ethernet > click on Advanced > TCP/IP > Configure IPv6 > Off > OK > Apply
(FOR LION: If you can’t see an option to turn ipv6 off, set it to link-local only.)

Internet not working - wifi connected but internet and server fail, ethernet cable doesn't work either

All of a sudden the internet on our Macbook Pro does not work. We connect through an Airport Extreme and other mac works fine. It shows that wifi is fully connected but when i go to diagnostics, i see the internet and server are failing. I tried connecting an ethernet cable and it doesn't work that way either. Have restarted and reset modem and router, nothing is working… help!

Hi ehamzic1,
Welcome to the Apple Support Communities!
I understand how frustrating it can be when your computer cannot connect to the internet. In your situation, you will need to isolate to find what is causing the issues connecting. I would recommend reading over and working through the attached article. The article should help you troubleshoot and resolve this situation.

Help! Internet and Server failure despite full connectivity

My internet access just completely stopped working recently. No matter where I am, neither Safari or Chrome will connect to the internet. I have tried to get on the internet using my home wifi and my campus internet and neither works even though it works for others. AirPort also shows full bar strength and says I am connected. Ethernet and FireWall say not connected. Network Diagnostics show that everything is green, except Internet and Server, which are red and say failed. IPv6 is set to "using DHCP" and "automatically" and the dns servers are 208.67.222.222 and 208.67.220.220. I have tried renewing DHCP lease and turning my computer on and off several times. I've emptied cache and all that. Also, nothing is checked under the proxies tab.
Someone please please please help me! I don't know how to fix this problem.

You MUST use the (Apply) button or close the window and save changes for these to take effect. Even at that, it sometimes takes a Restart to work properly.
If no joy from that, try using (Assist Me) > (Assistant) ...
...and set it up again from scratch, being sure to specify a new "Location", NOT Automatic.

ISP Problems - All network status LEDs are green, except Internet and Serve

System, Macbook Pro Airport Extreme, D-Link cable Modem.
Randomly I loose the internet. I run Network Diagnosis and it shows green for Airport Airport Settings Network Settings and ISP, but yellow and then eventually red for Internet and Server.
I run the Network Diagnostics and it usually will resolve the issue, but I'm wondering if I should be complaining to my cable company or changing some setting.

For anybody experiencing similar difficulties the solution was the security settings on the wirless router. I had to get Orange to access my Macbook remotley to change from wep to wap2.

IMac keeps losing ISP, internet and Server but still connected to wifi

My Imac keeps losing ISP, Internet, and Server but is still connected to the Wifi. To recnnect, I have to go into Netwrok Diagnostics - assist me. This is happening every twenty minutes or so (sometimes less). Can anyone help? I might add that we have recently moved house and never had this problem before.

Wifi problems seem to crop up a lot on here and unfortunately there doesn't seem to be a 'one fix' solution.
However, sometimes any one of the following can help although, unfortunately, not always. In no particular order:
Check wifi security - if it's WEP change it to WPA or WPA2 (preferably, as it's more secure)
Change the wifi channel on the router
Create a new Network Location: http://support.apple.com/kb/HT5289
Reboot the router
Also take a look at this link and the links within the article for other ideas. They mainly reference Lion, but still seem to be relevant to Mountain Lion:

My imac keeps losing ISP, INTERNET AND SERVER but still has WIFi

my iMac keeps losing ISP, INTERNET and SEVER but is still connected to the Wi-Fi and when I tern on the mac i have to connect it every time and it is on preferred net work its the Olney one then after I connect it works for about 20 min then stops and I got to network preferences and click on ASSIST ME - DIAGONSTICS and it shows ISP INTERNET AND SEVER ALL IN YELLOW.

Open System Preferences Network pane. In the sidebar, if you see things you do not use for networking, remove them (you can add them back later if they are ever needed). For example, if you don't use Bluetooth or FireWire for networking, remove them from the list of networking services. To do this, select the item on the list and click the minus sign at the bottom of the sidebar. You can leave Ethernet on the list.
NOTE: Bluetooth and FireWire networking is not related to their use for connecting devices.
Also, click on the gear icon at the bottom of the sidebar, and select Set Service Order. Make sure Wi-Fi (or AirPort for older Mac OS X) is at the top of the list.
Apply the change (and maybe restart your Mac as well). See if that makes any difference.

I cannot connect to Internet on Mac OS X 10.6.8 with any of my three browsers. Wi fi is working, modem and Ethernet working. Failed connection to Internet and server. What can i do to fix!!!!

Please help, I have tried unplugging everything.... Diagnostics etc...

Hi, this has worked for a few...
Though all of these steps may or may not be needed, I'm including them all.
Make a New Location, Using network locations in Mac OS X ...
http://support.apple.com/kb/HT2712
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 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.
10.4 instructions...
Is that Interface dragged to the top of Network>Show:>Network Port Configurations.
If using Wifi/Airport...
Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.
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.

80% failed internet and email server connections

We have two computers, mine described below and my husbands (iMac OSX 10.4.8 2GHz Intel Core Duo SDRAM, both with Airport extreme.)
we've had Adelphia High Speed Internet for a year with no problem; almost two weeks ago it switched over to Comcast and we've had trouble ever since. We've jumped through all the hoops Comcast put us through and a repairman came and gave us a new modem. He declared he knew nothing about Macs!! We are at a standstill now. Any ideas?
iBook G4 Mac OS X (10.4.8) 1.33GHz PowerPC G4 processor, 512MB built in memory

IS there a situation with Mac 10.4..8s that prevent it from functioning properly?
No
If that were so, why would we have had NO problem with Adelphia and when they switched over to Comcast it hasn't been working?
Exactly! It is a Comcast issue not a Mac OS issue.
Of course the real kicker is that the Mac OS has absolutely nothing to do with the connection between the AirPort Extreme base station (AEBS) and the Comcast modem. The AEBS works just as well with Windows as it does with the Mac OS. What story would they be giving you if you were using Windows?

Internet and Server is red

My wireless router is working perfectly fine.
I have tried turning it on and turning it off
but the red lights dont leave and I can't access the internet.
what can I do to fix this issue?

How can you be sure? What is its brand and model number?
but the red lights dont leave and I can't access the internet.
What "red lights" do you mean?
Please edit your "public profile" to include (a) your model of computer and (b) your operating system. Some of the advice you may need will depend on those details.

ISP, internet, and server failures constantly.

This has been happening for quite a while now, after 10-15 minutes I will always disconnect from the internet but still have full strength wireless activity.
This is not restricted to my home network as this happens at almost every wireless network I've used.
Does anyone know anyway to fix this?

My Macbook and my Neighbours is doing the same thing. Has been perfect for years, then about 3-4 weeks ago, its on & off etc etc. Hence me being on here looking to see if there is a known bug. Neighbours Macbook just the same, i.e. 3-4 weeks ago......

Is there any simple way I can find out whether my router or my mac air is responsible for dropping internet connection constantly? Often when I do the network diagnostic, the wifi light is green, but isp internet and server are either amber or red.

This is driving me crazy. The router (it came with the apartment) is a Fritz!Box fon Wlan 7240. I would be willing to buy an new airport if that would fix it. But in this country (Germany) you probably can't give things back.

This is not an alternative to Susan Howard's diagnostic questions, only an atempt to collect more data about your situation.
Do you have the instruction manual for your router? I ask because at some point it might be a good idea to reset the router. Turning it off for about 15 seconds then turning it back on helps sometimes. The more basic procedure (this is with my router) is to push the reset. But that would mean you have to re-configure the router with password etc. from scratch.

ISP Failed, Internet Connection Intermittent

     For a long time, my internet connection has gone through phases in which pages, images, videos, etc. stop loading something like every 1-2 minutes. I have seen gifs start loading incredibly quickly, in real time almost, then stop dead. Refreshing in this case yields an endless period of loading. I am fairly certain that this problem extends to all devices on my wireless network, but I rarely use two computers simultaneously, so I'm not certain of this. The problem is usually present for a few weeks at a time, then is stops happening for a month or two, if I remember correctly.
     Whenever pages fail to load, I have found that, by opening Network Diagnostics (System Preferences>Network>Assist me…>Diagnostics…), I can temporarily restore internet connectivity. The Network Diagnostics window usually has orange lights for ISP, Internet, and Server when I first open it, though ISP's light is sometimes red. As I proceed through the program, the lights usually change after I select my network from the list. Network Settings will sometimes turn red, at which time all the lights below it will turn red as well. Whether or not this happens, though, the lights end up as green, and I am told that my internet connection seems to be working correctly. Most of the time, my internet connection will then work for some time (the length of which may vary). I have pored over all of Apple's network troubleshooting articles, none of which have resolved my issue. I have restarted my router and modem in the past, though not recently. I do not believe that the problem lies in either my iMac or wireless router (Time Capsule, 2 terabytes, 4th generation or earlier), as my modem (or possibly cable splitter) seems the liklier culprit, but my landline phone service and cable television service has not seen any service disruptions (all 3 services operate over the same cable, and are provided by the same company).
     During a recent interruption of service, I used the ping command in Terminal to try to connect to the 8.8.8.8 server. The full text of the command and its output is as follows:
Rays-iMac-8:~ lorenzocastoldi$ ping 8.8.8.8

I followed this with a traceroute command to the same server.

I can't find much on this "sendto: No route to host" message, but the few forum posts I was able to find seemed to be made by users of the Linux operating system, or variants thereof, making me even more certain that the issue is with my modem, cable, or ISP. After running Network Diagnostics again, I got this

for ping, in that order. I believe I've heard that the second entry in traceroute, with the three asterisks, is my router. Whenever I run traceroute, entry 2 is always like this, and I think this is the case for other people as well. This would mean, if I am not mistaken, that the first IP address, 10.0.1.1, is the weak link. However, I do not know how to proceed from here. When I traceroute other websites, it always appears as IP address number one, and it is contacted before my router, if #2 is in fact my router. I have read that 10.0.1.1 is also a private IP address, though I do not know exactly what that would mean for me. I am tempted to think that this IP address may be my computer itself, but that wouldn't make sense. It may be my router, again, but I do not know this for certain.
Because this is an intermittent problem, it can be difficult to examine it in any detail, but I should be able to answer most questions about it. If anyone has any potential solutions, or even hypotheses as to the nature of the problem, please let me know. I cannot solve this problem on my own.
tl;dr: What is the 10.0.1.1

I acknowledge that service outages are common, but they shouldn't interfere with my computer's connection to my router, nor should they last for weeks straight or be temporarily resolved by running a diagnostic tool. Plus, my phone and T V would probably go down in that scenario, except for some very special situations. Electromagnetic interference is an explanation I hadn't considered before, but I don't run a cell phone or microwave all day, but only every other month. I'll look into it though—maybe I'll see how my computer communicates with my router during an interruption, or see if any large electronics are running at the time. However, my connection's been fine since I started this thread, when I restarted my base stations. Maybe that's all I needed to do after all. A strange issue nonetheless, though.

AirPort can't connect to Internet or Server

Hello everyone!
My mac's wireless was working more or less fine until 2 days ago, when suddenly it couldn't connect anymore. I know it's not a problem with the wireless connection itself, because we have 2-3 other computer connecting to it without any problems. When I go through the diagnostics, everything is indicated as green except Internet and Server, which often fluctuate between green, yellow and red.
I've had a browse for similar problems, and came across this discussion here: https://discussions.apple.com/thread/3044354?start=0&tstart=0
I followed the advice there and checked whether or not my mac could connect to specific IP addresses of websites, which it can. But other, normal internet addresses, it can't. However, the replier didn't give any concrete solution to the problem (or I just didn't understand it), so I made a new discussion page. If you have any suggestions, please help. I'm out of ideas.
Thank you!

Please try each of the steps that follow, in order, until resolved:
STEP 1
Create a New User Account
