Can't Connect to Internet via Ethernet Cable.

Hi
I've looked around but haven't found anyone with exactly this problem. I can't get my MacBook Pro to connect to the internet via ethernet at my dorm. I am on the same connection with the same cable on a different computer right now, so I know that is not the problem. When I plug the cable in to my MacBook Pro it tells me that the cable IS connected, but when I try to go on a site on either Safari or Firefox, it takes a couple minutes trying and then tells me that I don't have a connection. I guess the problem lies somewhere between the connection and the browser. I am using DHCP (I don't know what that means but that's the default and other posts have said to make sure that that's what one is using) and the "connect using PPPoE" box is not checked. My ip starts out 192 etc. so I assume it isn't self-assigned. I WOULD LOVE ANY HELP YOU CAN OFFER.
I just got back to school today and this is already making this semester pretty awful.

I am having the same issue. Everything was working hunky-dory but then just up and stopped. The Airport works ok, but considering I am leeching off someone else's across the hall, that is not the most reliable solution.
In my Network Diagnostics, the Ethernet connection is given a green light, but the it seems unable to find the internet at all.
I have reset the router several times, restarted my computer several times, and various combinations of the two, as well as changing ports and cables etc...
any suggestions?

Can't connect to Internet via ethernet

I have two brand new 11" MacBook Airs. I can connect to the internet via ethernet on one and not the other. I little back story...
I previously had two 13" MacBook Pros and had the same issue – one could connect to the internet via ethernet and one couldn't. I used migration assistant when I upgraded to the new MBAs, so I believe I carried over a setting from the previous "problem" comuter to the new one. Interestingly, both of my MacBook Pros connected to the internet via ethernet just fine until, for reasons unknown to me, one day one would no longer work.
When I look at diagnostics, the lights are (from top to bottom): green, yellow, green, red, red
Is it possible to revert some ethernet networking setting to factory?
Thanks for any help you may be able to provide.

The same thing has happened to me, it just stopped working. No, I've had this problem for a long time with this machine, but the other day I was downloading some large files, and all the files dropped down to nothing, internet was gone.
It will connect to Wireless, but now I'm even having problems with that.
If I plug in the Ethernet cable but set it to use AirPort, it won't find the web. I have to unplug the cable and it will use AirPort -- not good when I need to access hard drives! It had been working with it plugged in, but it just stopped. (I don't know if it was using the Ethernet or the AirPort at the time.) I wasn't messing with any settings at the time.
Tried restarting, running diagnostics, using different browsers, various websites, didn't help.
It's a MacBook 2,1 -- 2.0 GHz, Intel Core 2 Duo -- 10.4.11
I have a G4, same OS, using the same router, same settings, everything. G4 works perfectly.

IMac Won't Auto Connect To Internet Via Ethernet Cable

I'm Using An iMac OSX Leopard, And When I Turn On My Computer The Internet Isn't Connected Even Though It Works. I Get Server Not Found In Safari And Firefox. I Have To Unplug The Ethernet Cable And Plug It Back In For It To Work, But If I Turn Off The Computer When I Turn It Back On It Doesn't Work Again. When I Open Diagnosis Everything Is Connect Except For Internet And Server Until I Unplug The Ethernet Cable And Plug It Back In. I Tried Using WiFi But The Same Thing Happens; The Internet Works, But It Doesn't Auto Connect Even Though The Computer Is Set To Remember The Network And Connect Automatically. There Is No Firewall On. Are There Any Solutions? Thanks For Your Help.

Have you tried System Preferences/Network/Assist Me/Assistant?

Macbook Pro suddenly will not connect to the internet via ethernet cable.

I know this is a long shot... but I figured I would give it a try.
My macbook pro suddenly does not connect to the internet via ethernet cable. Please bear with me, as I am not very tech-savvy - I will try my best to describe the symptoms!
I connect to the internet via ethernet (we don't have wifi). It was working before I went to work, and when I came home I suddenly couldn't get anything to work (I know everyone says this, but I truly didn't mess with anything). Internet browsers just think for awhile and then turn up the 'You are not connected to the internet' error.
I went into my network preferences and curiously, the 'Ethernet' shows a green dot and says 'connected'. However it says 'Authentication server is not responding' underneath the last part that says '802.1X: WPA: eduroam' (I think that is my user profile).
When I go into my 'security' settings I can see that my firewall is off, so that shouldn't be causing any problems.
I've tried restarting the router and computer itself many times. Diagnostics just gets to a certain point and reports back 'Network Diagnostics cannot fix the current networking problems.' I've also tried switching to a different ethernet cable, and I tried both cables out on a PC laptop and it connected without issue. Additionally, I brought my macbook along to a friend's house and it connected to his wifi just fine, so the problem appears to just be with ethernet connections.
I know it's hard to troubleshoot this kind of thing without being there and having a look at the computer yourself, but any tips wouild be greatly appreciated.

As I mentioned above, I am not very tech savvy so I have no idea why a wireless protocol would be showing up there, I'm just listing everything I see in hopes that someone might know something I can try. This is why I am asking for help here - I'm not sure what has happened that has made me unable to connect, especially since it seemingly occured while nobody was using the computer.
I guess I should clarify that I'm not a total hillbilly- normally my firewall is set to 'on', but I set it to 'off' to try and troubleshoot the issues here as I was told that sometimes it can interfere with the computer's ability to connect to the internet. If this is not the case and firewall does not affect anything, I will turn it back on while I try to fix this.
I have tried the method you mentioned above a few times - I actually contacted my ISP earlier this week and they recommended resetting the router like that. They didn't mention any known network issues.

"Connected to internet via Ethernet" ... but won't work

Looks like I have it set up correctly. Says "Connected to internet via Ethernet", yet I am getting absolutely no internet. Where have I gone wrong?
Oddly enough, it even says this when there is no ethernet cable plugged into it and is blinking amber.
What is going on?

Assuming you have a cable or DSL modem cabled to the Airport Express ethernet port... pull power to both the modem and the Airport Express for five minutes (or up to thirty minutes if you can stand it). Then plug power into the modem and wait a minute. Then plug power into the Airport Express and wait a minute. Hopefully your connection with your ISP will now have reset, and the Airport Express will get an IP address and show a solid green status light.

Can't connect to internet via MacBook Pro to Airport Extreme

I can't connect to internet via MacBook Pro to Airport Extreme. I reset AE and modem (power down and back up again). Some computers on my home network will connect fine and others won't. The ones that won't don't populate the DNS server or the Search Domains. AE shows up on all the machines. I have one computer also connect to AE via ethernet and it has the same symptoms. Why do some Macs connect and others don't. Even when I get them to connect when I shutdown or put in sleep mode over night I lose the internet connection and have to start all over. Very frustrating.

Regrettably no replies. I have struggled with this for days with no success and I have given up on the Airport Extreme. I have found several other Forum posts with very similar problems and no one seems to have a solution to this. It seems other wireless routers work better than the Apple product. I was able to get my old Linksys wireless router reset and it is set up and working well. The Linksys router does populate the DNS servers and domains where as the AE does not. Apple engineers should look into this. If I am mistaken and there is a fix for this someone please let me know, otherwise my AE will probably appear on Ebay very soon.

IMac G5 won't connect to internet via Ethernet

So i have an iMac G5 that isn't connecting to the internet via ethernet.
I have already taken a look through all the Network Preferences, tried going through the network port configurations and setting all of that up again, created a new location for it.
I tried turning off the modem, and letting it restart - restarted the iMac - tried to set up all of these settings again.
I also created a test user account to see if it would work there - still nothing.
I hooked my own 17" MacBook Pro to it and it works perfectly. I never had to go through any settings on mine - it just worked as soon as i plugged the Ethernet cable in.
So the modem itself works - because my computer works. What else could be the problem?
I went through the Network Diagnostics on hers - all green dots and it says that the internet connection is working perfectly. It gives me an IP address - but it still won't load a webpage, and it tells me there that i am not connected to the internet. I am all out of ideas.
If anyone can help me with this it would be greatly appreciated. Thank you so much!

What OS you using? 10.5?
My memory of 10.5 is fading so you may need to figure out the vague instructions.
To make this easier to type Macbook Pro = MBP
When testing disable wifi & use ethernet on both machines.
Are both set to use DHCP? Or are you using manual settings?
Compare the IP addresses of the MBP & the iMac when they both use ethernet.
Compare the subnet masks too just to be sure nothing is different.
Does the iMac do any local networking at all? (e.g. is iTunes or File sharing visible on it). see *
Does it see the MBP in the sharing sidebar or can it connect to anything on the local network?
Have you connected the MBP to the iMac using the exact same cable that the iMac connects to the router?
Does the MBP work if connected to the router using the iMacs ethernet cable?
* You will need to enable file sharing to see the shared Mac in the sidebar (or have mother service shared). Enable it in System Preferences > Sharing whilst you test.
If you are have local networking in a functional state it could be…
DNS - what is the iMac DNS set to on each Mac?
Are either of them showing a grey DNS entry in System Preferences > Network? That means the router is supplying that info.

Can't connect to Internet via Airport

I have a PPPOE ISP account. Before upgrade to Lepoard, just fine. Now I can only connect to internet using cable via my router moderm. I cannot connect my wireless router.
The wireless router will appear to be connected but it said self assigned IP. If I hardcode an IP eg. 192.168.11.2 to it. The Airport status will become connected but still cannot dial into my PPPOE account. An message no PPPOE service will appear. But if I plug in the LAN cable, everything work fine. Why this happen? My wireless router work fine with my Window XP and my Mac (before upgrade to Lepoard) What configuration should I change? I am an idot to networking. I have download all patch and has tried boot to safe mode etc.
Anyone can help?

By power downs do you mean Sleep?
One thing that might work is to set the IP to Static in Network>Configure IPv4>DHCP with Manual Address.

Time Capsule connected to internet via ethernet and static IP address

Hi! I'm at my wits end and getting no help from my IT department. I want to use my Time Capsule to create a wireless network within my office. I can directly connect my TC to the internet via ethernet and an assigned static IP address. However, doing so I'm unable to connect to the internet using the created wireless network on my laptop. I've tried using the bridge option for sharing as well as the "sharing an IP address" and neither configuration is working. any thoughts?

I have the same setup; my ISP uses static IP only. No probs configuring a LinkSys router but with TC it's not obvious where to plug in the info. Can't ping the TC router via IP address to setup directly like the LinkSys which would be simple. Is the out of box router address really 10.0.1.1 on the LAN side? I want to use the 192.168 sequence and have changed it but still no success as I can't determine where to put the static IP! Can you give me something specific? By the way, it works fine thru the LinkSys router in Bridge mode.
Thanks,

Have new satellite L500 laptop that can't connect to internet via a Ethernet cable

This laptop can connect to a wireless network but when we try to connect using the Ethernet cable we get a limited connection unknown network message.
I am getting all my information second hand from a niece I bought the laptop for who has it at university. She has had tech support out from the university and they say its a configuration issue on the laptop and not problem with the cable or connection.
I have read on some websites that Norton anti virus could be an issue? But I had removed this and installed Kapersky. Any ideas?

This laptop can connect to a wireless network but when we try to connect using the Ethernet cable we get a limited connection unknown network message.
The wireless connection uses essentially everything necessary except the plumbing.
Which Satellite L500?

Can't connect to Internet via Airport but CAN via Ethernet

Yeah so I have tried TWO different of my AX's and can not connect to the internet via EITHER even though Network Status says "you are connected to the internet via Airport". But, if I hook the ethernet cable directly to the computer from the modem it connects to the internet fine. What am I missing. Oh yeah, and on one of the AX's the "music" tab does not appear next to the "WDS" tab thus not allowing AirTunes on that AX, any ideas on that too? PLEASE HELP!!

CONNECTED!! After resetting the modem, llike you suggested, I am able to get the wireless network back up and running, BUT...I am still having problems with one base station not showing the "music" tab and thus not letting me stream music to it. When I hit "configure" the tab shows for a quick second then disappears. Any idea?

HT4889 I can connect both computers via ethernet cable?

I recently bought a new retina display MacBook Pro and have files and applications I want to transfer over from my big clunky Mac to my new laptop for college (audio engineering).
I want to save some money and not buy a firewire or wait like 5 hours to transfer everything via my wi-fi network so is it possible to use the ethernet cable to transfer everything?

Yes. The Mac's Ethernet ports are autopolarizing and will self-assign an IP address from the 169.x.x.x reserved pool. However, I fail to see how you are going to plug in an Ethernet cable to a Retina Mac without an adapter.

Airport Time Capsule 3TB can't connect to modem via ethernet

Hi all,
Thanks in advance for any assistance on this issue ...
I am having extreme difficulty in connecting my Airport TC to my modem via ethernet. Ideally, I want to use it to extend the range of my wifi, as well as back up my machines.
I can't get the AP TC to add on to an existing network in initial set up as , even though the option is available, the Airport Utility (6.3.2) doesn't seem to keep it selected, and wants to create a new network.
When I create the new network, my internet connection drops out, even though the modem indicates that it is connected. I then edit the internet connection in AU by telling it to extend the existing network (add in the SSID etc) which picks up the internet connection again, but then the Airport TC drops out, and all I get is a blinking amber light and a message saying no configured Airport Base Stations detected, continuing to search.
I have no doubt that it is something I am or am not doing. I have soft, hard and Factory reset the TC, reset the modem, changed cables, pretty much everything my tiny brain can think of.
I have looked through the support pages and follwed thier advice, with no luck.
Help please.

I can't get the AP TC to add on to an existing network in initial set up as , even though the option is available, the Airport Utility (6.3.2) doesn't seem to keep it selected, and wants to create a new network.
"Add" would be used for a wireless connection....and you indicate that you are using Ethernet to connect the existing modem/router and Time Capsule together....so the correct setup would be to create a new network using the exact same wireless network name and password as your existing network.
Connect an Ethernet cable from one of the LAN <--> ports on the current modem/router to the WAN "O" port on the Time Capsule.
Here, I am assuming that the TC will be located at least a room or two away from your main wireless router. If it is located any closer, there will likely be wireless interference issues between the two routers. The wired connection between the modem/router and Time Capsule must be maintained.
AirPort Utility will suggest a setup that looks somewhat like this.....except you will see a Time Capsule instead of an AirPort Express as illustrated below:
Network Name would be the name of your existing wireless networik
Base Station Name is a device name that you want to call your Time Capsule
Password is the wireless password of your existing wireless network
Verify confirms that password
Click Next and the setup utility will auto configure things for you in a minute or two
When you see the message indicating Setup Complete, click Done and you should have a green light on the TC.

Can't connect to internet via router and airtunes at the same time

Can anyone help me connect to the internet via my BT Homehub, and play AirTunes through my Airport base station at the same time? I can only seem to do one at a time.
I've seen the articles about setting up clients etc but don't get it. Using the Airport Assistant utilty doesn't really help either. Would like someone to go through the steps I need to follow.
Thanks

To set up AirTunes on the AirPort Express Base Station (AX), connect your computer directly (using an Ethernet cable) to the Ethernet port of the AX, and then, use the AirPort Admin Utility to check these settings:
AirPort tab
- Base Station Name: <whatever you wish or use the default>
- Wireless Mode: Join an Existing Wireless Network (Wireless Client)
- Wireless Network: <select your BT Homehub wireless network>
Music tab
- Enable AirTunes on this base station (checked)
- Enable AirTunes over the Ethernet port (optional)
- iTunes Speaker Name: <whatever you wish>
- iTunes Speaker Password (optional)
In iTunes:
iTunes > Preferences... > Advanced > General
- Look for remote speakers connected with AirTunes (checked)
