AEX not recognizing internet via ethernet cable

This is an odd one.
I'm housesitting and my friends have a dsl box with ethernet out to connect to the net. If I plug the ethernet cable into my computer I'm online, period.
If I plug my AEX into the ethernet cable, I can't access the net. I can connect to the AEX fine, but it doesn't recognize that there's an internet connection.
When I plug my AEX into the ethernet cable at work, it connects to the net immediately.
Any idea what to do to resolve this?
Thanks,
Tom

A couple of reasons may be causing this:
1. Since you switched out the device (computer vs AX) connected to the DSL modem, you might have not provided enough time for a complete power recycle...so that the modem can "recognize" the AX.
Modem/Router Power Recycling - Quick
o Power-off the DSL/Cable modem, Internet router, & computer(s); Wait at least 5 minutes.
o Power-on the DSL/Cable modem; Wait at least 5 minutes.
o Power-on the Internet router; Wait at least 5 minutes.
o Power-on the computer(s)
If this fails to get the modem to "recognize" the Internet router, then try the "Full" version.
Modem/Router Power ReCycling - Full
o Power-off the DSL/Cable modem, Internet router, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
o Power-on the DSL/Cable modem; Wait at least 30 minutes.
o Power-on the Internet router; Wait at least 5 minutes.
o Power-on the computer(s)
2. The ISP requirements for Internet connectivity may be totally different (PPPoE vs DHCP) between your friend's network and the one you use at work.

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.

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?

Internet via ethernet cable not recognised: just wireless

Hi -
I have an ethernet cable that supplies my internet, but Windows Vista (Home Premium) will only let me access a Wireless connection (of which I don't have one!).
Can anybody help?
Thanks!

anch66,
Could you please provide a little more information. Who is your Internet Service Provider (ISP) and what are their minimum system requirements?
Our G3 that connected to the web for years with OS 8.1 no longer connects because we changed providers. Juno requires OS X to load pages. We can connect to the server with the right settings but then it does nothing to load a page because the minimum OS requirements are not met.
Gmail is similar. It requires OS X to set up an account. I had my son set up the account on his G5 and then we could access it with OS 8.1 on the G3. The devil is in the details.
Do you have a second hard drive or a partition on your drive to give you a backup if the upgrade does not go well. Buying an install CD would give you a little better upgrade path.

Really frustrating - Macbook not recognizing built-in ethernet cable

I am a college student who purchased the macbook one year ago
My macbook is not recognizing the ethernet cable plugged into it.
I thought it was the ethernet cable itself but I tested my roommate's cable and it wasn't also recognized (his computer's internet works fine)
This is frustrating because I am relying on the college wireless and the signal is flaky at best from my dorm
I am guessing that either some harddrive or software is messed up
Anyone can help me?
Do I have to go to the apple store? My warranty is expired and a very busy semester is about to start so I don't want to send it in for a long time

Have you used the MacBook in multiple locations in the dorm (on the same subnet)? If you connect through a mini-hub or -switch (rather than plugging directly into the Ethernet port provided by the school), the hub or switch may be holding on to the MacBook's MAC address even when the MacBook is disconnected. When you then plug in in another room, the school's networking equipment may think that the same MAC address (the same computer) is connected on two ports at once -- which just doesn't work. You may get an IP address, but be unable to do anything; or you may get a 169.x.x.x IP address. The school's networking folks can look at the network infrastructure equipment -- the big switches in the wiring closets -- to see if the MAC address is registered on multiple ports.
The best solution is to replace those bad min-hubs or mini-switches -- they shouldn't hang onto MAC addresses for computer that are no longer connected. But if that's not an option (or just to test the theory), unplug (power off) every hub or switch you have plugged into, and see if you can get online after powering them up again. You would have to power cycle the hub or switch every time you use one.
Another test is to try to connect somewhere else on campus, on a different subnet. If it also doesn't work on another subnet, the solution described above does not apply. There are other potential culprits, such as the subnet running out of IP addresses, rogue routers installed by other students, and needing to register for the school's network, misconfigured network settings, and of course, defective hardware. You might try starting up from the MacOS Installer disc and running the Network Utility to rule out misconfigured network settings.

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 will not connect to the internet via ethernet cable anymore.

My MacBook apparently decided the other day that it no longer desired to connect to the internet through an ethernet connection; it still works perfectly through a wireless network. I am a university student and so there is wireless almost everywhere so it's not so bad, but I cannot connect in my dorm and it's becoming a bit of a pain. I have tried to connect through several known working ethernet ports and no matter what my computer thinks it's not even plugged in. It's even more strange because I just woke up one morning and it was no longer working. Everything else it totally normal, save this one little inconvenience. Any ideas?

So I'm having the same problem. I woke up one morning and my macbook's ethernet connection suddenly stopped working. For some reason It wont recognize the cable.... I have tried 3 different cables and theses cables work with my sisters PC so I know the cable is not the issue. Im also living in college dorms which seems to be a commonality with this issue. I've searched for answers all over and I really don't have the time to make it to the mac store anytime soon. My wireless works but it's not allowed in my college dorms for security reasons(lame). Please help!...
Apple needs to formally address this issue.

Want to connect MacBook Pro to the internet via ethernet cable for the first time?

I Plugg the cable for Ethernet> Then I type my IP adress> don't know what to type in these blanks:
Subnet Mask, Router
What DNS?
I want to plug the cable for Ethernet then see the internet work?
=

We cannot answer your questions.. and the method looks wrong.. why are you doing it manually.. just use dhcp and see if it works.
There is hardly a modem or router out there that doesn't have dhcp setup for automatic setups.
If it is manual then there is no way we can give you the values..
They are determined 100% by the network you plug the computer into.. and the setting of that network.
Tell us more if you supply modem router.. and ISP info and why it is not working with dhcp we might be able to help further.

Internet via Ethernet - new password from ISP, problem to connect now

Hello folks,
switched to Mac 1 year ago and found alot of great information in this forum. Thanks first !
But I´m also facing a problem:
(white iMac C2D OSx 10.4.11)
I used to connect to the Internet via Ethernet Cable and my DSL-modem (PPPoE). iMac also connected to Internet automatically. Great so far.
But then I got a new password from my ISP.
I changed it in the System preferences (also checked in Keychain, correct one is in there) and now my problem:
- when I go <...>-icon, click "open internet-connection", and then click manually "connect", my Mac connects to Internet
- when I go to <...>-Icon, then directly click "connect" -> no connection possible -> password not accepted ?!?
- when I activate "autmatically connect to Internet when needed" in the PPPoE options -> also not possible -> password not accepted ?!!
Is the old password stored somewhere on my Mac? I also tried to delete my ethernet connection and set up a new one, but I´m always facing the same problem? What´s wrong here ?
Hope you guys can help me !
Thanks & best regards from Germany,
Satch

Just followed your instructions and created a new 802.1x connection, entering my data etc. When I click "connect" status says "connecting" and that´s it, nothing happens.
What I don´t understand is, why do I have to create some sort of new and different connection. I mean, everything was working fine with "Ethernet (integrated)" until I changed that damned password. Isn´t there a possibilty that the old one was saved in a chache (or system file etc.)?
Too bad, it´s really the first problem I face in my one year plus Mac experience!

PowerMac G4 will not connect to the internet via ethernet

I am normally a very mac savy person, but I cannot get this to work...
I have an Airport Express connected to speakers, a USB printer and an ethernet hub, which is connected to a cable modem and also a PowerMac G4 via ethernet. There is also a wireless iMac thrown into the mix. All hardware has up-to-date software.
The wireless iMac gets online, prints and plays music wirelessly.
The wired PowerMac G4 will not connect to the internet via ethernet, it is killing me.
I have gone through all the settings and cannot figure this one out. I really appreciate all advice.
Thanks,
G4 Mac OS X (10.4.8)

Hi pradagirl,
Welcome to Apple Discussions!
Leaving the other peripherals out, tell us the connection sequence from the G4 outbound.
Also, you might gain more insight at the Networking Forum

EA6900 Internet Connection Issue - Desktop connected via ethernet cable

Hi there,
I have an HP p6837c, 64-bit OS with Windows 7 Home Premium. It is directly connected to the EA6900 via ethernet cable. My internet connection constantly drops (as in variably every 5 seconds to 5 minutes) then re-establishes itself. I have no internet connection issues when directly connected to the modem. All of the wirelss devices that are connected via the EA6900 are working without any issue. My husband's laptop, which has Windows 8.1, functions with no problem when directly connected to the EA6900 via ethernet cable. We've tried swapping out the cable. We've tried adjusting the MTUs per Support's suggestion. Nothing has solved the issue
Any thoughts on what the issues might be? Settings? The version of Windows? Any help would be much appreciated!

Internet Service Provider and Modem Configurations
What ISP Service do you have? Cable or DSL?
What ISP Modem Mfr. and model # do you have?
Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
What ISP Modem service link speeds UP and Down do you have?
Check cable between Modem and Router and PC, swap out to be sure. Link>http://en.wikipedia.org/wiki/CAT6 is recommended.
Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask.
I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. For cable Internet, RG-6 coaxial cable is needed, not RG-59. Check for t.v. line splitters and remove them as they can introduce noise on the line and lower the signal going to the ISP modem. Connecting to the ISP modem could result in a false positive as the signal to the modem could be just enough to that point then adding on a router, could see problems. The router operation is dependent upon getting good data flow from the ISP modem and the modem is dependent upon getting good signal from the ISP Service.
Router and Wired Configurations
Setup DHCP reserved IP addresses for all devices ON the router. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting and maintain consistency for applications that need to connect as well as mapped drives.
Ensure devices are set to auto obtain an IP address.
If http://en.wikipedia.org/wiki/Ipv6 is an option on the router, select Local Connection Only.
PC 3rd Party Security Software Configurations
Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.

Wirelessly
Just select the option to make your AirPort Express join an existing network in the setup process

My Apple TV will not update to the latest software, dose anyone know what the problem is, I've reset, tried to do it wirelessly as well as while connected via Ethernet cable.. Both have resulted in the same message!!

My Apple TV will not update to the latest software, dose anyone know what the problem is, I've reset, tried to do it wirelessly as well as while connected via Ethernet cable.. Both have resulted in the same message!! Update unsuccessful, current software version is 5.1 (5201) . I've rented a movie recently and does not appear in my movie list, but I have been charged for this movie, can someone help me out with these issues.

If your problem persists get yourself a micro USB cable (sold separately), you can restore your Apple TV from iTunes:
Remove ALL cables from Apple TV. (if you don't you will not see Apple TV in the iTunes Source list)
Connect the micro USB cable to the Apple TV and to your computer.
Reconnect the power cable (only for Apple TV 3)
Open iTunes.
Select your Apple TV in the Source list, and then click Restore.
If when you choose restore you get a message that the device cannot be found, download the file below
Apple TV Software Restore 5.1.1 (2nd generation)
Apple TV Software Restore 5.1.1 (3rd generation)
Then hold down the option key while choosing restore and select the downloaded file when prompted.

I have att u verse modem and it wifi was not working. So i got netgear wifi an d i connected my apple tv via ethernet cable to att uverse modem . i did not want slow dowm my wi fi speed. Now airplay is not working .

i have att u verse modem and it wi fi was not working. So i got net gear wi fi and connected to att modem . i connected my apple TV via Ethernet cable to att uverse modem . i did not want slow down my wi fi speed. My Apple phone is on Netgear wifi .Now airplay is not working .

Make sure that the Att Modem goes to the netgear router via ethernet cable. Then connect your Apple Tv with a ethernet cable to the back of the net gear router. Airplay wants it to both be connected to the same device, usually.

I recently purchased a MacBook Pro and transferred data from my MacBook via Ethernet cable. I did not consolidate my accounts and kept using my MacBook. Can I update the data transfer now using Ethernet and can I consolidate my accounts?

I recently purchased a MacBook Pro and transferred data from my MacBook using Migration Assistant via Ethernet cable. I was confused about consolidating my accounts, so I continued to use my old MacBook. Can I now update the data transfer using the same process and begin using my new MacBook Pro exclusively? How do I consolidate my existing accounts?
Thank you.

Of course. It does everything it did before Yosemite. You just won't be able to send or receive SMS messages with it.
