Ethernet is incapable to the internet

Hi,
my MacBook Air is 2013mid, OS 10.10
Few days ago, I could surf the internet through my Apple USB Ethernet Adaptor via cable line. However, it did not work since 3 days ago.
I cannot figure out what's going on currently. And I only surf the internet through WiFI now.
Could you help me fix this problem?
I did not upgrade anything recently after I upgrade to OS 10.10. Thanks for your help.

Connect the printer to the router usung the Wireless Setup Wizard on the frot of the printer.
Your computer will be able to connect to the printer as long as the computer is connected to the same rouer (yes, even with an Ethernet cable, it will be able to communicate with the printer).
Let me know what operating system you have and what router you are using and I can provide more specific help.
Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.
I am employed by HP

How do I use the airport express to connect a remote PC via ethernet cable and access the internet via wireless connection, How do I use the airport express to connect a remote PC via ethernet cable and access the internet via wireless connection

Trying to connect my xbox to the airport express. Have wireless in home and do not have a ethernet point behind tv/xbox. How do I configure the airport express to connect to my wireless network and then the airport express can use its connection via ethernet to connect the xbox to the internet.

Is your AirPort Express Base Station (AX) a 802.11n model? If it is, you can reconfigure it as a wireless Ethernet bridge or ProxySTA. This would allow the AX to join another wireless network and have its Ethernet port enabled for wired clients, like the Xbox 360.
To activate ProxySTA, you must set up the Express to join a wireless network and then enable the Allow Ethernet Clients setting; both settings are located in the Wireless tab of AirPort Utility.

Does my airport express need to be plugged to an ethernet to connect to the internet?

I am trying to set up my airport express so it can be connected to the wireless internet in my home, but no necessarily through ethernet chord so I can use the speakers with it in the other room.

Your Express does not require an Ethernet connection in order to gain Internet access. It must however be connected to another router that does via a wireless connection.
However how you would configure the Express to do so would depend on, whether or not, that other router is another Apple product (Express, Extreme, or Time Capsule).

Multiple ethernet networks show and the internet doesn't function on T400 with windows 7 64bit

Hello all we are having an issue with several T400 notebooks which i hope someone can help with.
the first symptom is no internet connection on the wired port-wireless has been turned off so it doesn't interfere with testing.
the network and sharing center shows multiple networks on the local area connection, one work (a domain), one public why the public one is there i don't know.
ipconfig shows it is getting an ip and dns through dchp and they are proper but two gateways are showing up one proper the other 0.0.0.0 this is where it is dying (i think)
i've done a route -p delete 0.0.0.0 but it doesn't persist through reboots for some reason.
so every reboot you have to run the route -p delete (administrative cmd prompt required) and then a release and renew and it works properly until it is next rebooted.
Does anyone know a way to get rid of the 2nd network? Beside the "public network" shows local area connection same as beside the work network if i disable one it disables the adapter and neither works.
Thanks for any help you can offer.

Time Capsule won't connect PC to the Internet

I'm sure there's something simple that I'm not doing but I can't get my PC to pick up the Internet from my Time Capsule. The TC is wirelessly connected to a BT HomeHub and is backing up my MacBook over Time Machine but why won't my PC, which is connected to the TC via an Ethernet cable, pick up the Internet?
Am I trying to get it to do something that just can't be done? Once TC is joined to another network, can it not then act as a bridge via an ethernet cable to provide internet access?!
I've wasted many an hour trying to get this to work, but to no avail.

Did you happen to upgrade to 7.6.3 on the TC?
That would be pretty funny if the new firmware causes all non-apple wireless products to drop out.
I think we could get a very big fight going over such a thing.
Although I don't know the reason.. apart from that dreadful firmware.
Apple names are a problem.. why it should hit now after working fine I am not sure.
But you need to do a full factory reset to the TC.
Then give it all SMB compatible names.. (ie comply with windows networking).
That means short, no spaces, pure alphanumeric.
That will include TC network name, wireless names (different name for 5ghz) and hard disk share name.
You should use WPA2 Personal security. With a pure alphanumeric passkey of 10-20 characters.
Use fixed wireless (radio in Apple Speak) channels. For 2.4ghz there are only 3 non-overlapping. 11, 6, 1 and test them in that order. 5ghz doesn't usually matter so much but test down low.. say channel 40 and up high 157.. or ones near that in your country.
Tell me if you still have issues..
And go back to 7.6.1 firmware. Hold down the option key and select previous firmware if you are on 7.6.3

Airport Network Doesnt Connect to the internet!

Hi,
I recently had a long powercut in my area and when the power finally came back on my netgear router would no longer connect to the internet and not even push out a signal (the ethernet cable still feeds internet when plugged directly into the macbook however). I figured the powercut damaged the router and replaced it with the new Apple Base Station Extreme as I already had an Express extending my network via another ethernet cable upstairs which worked fine.
The problem is still there with the new router. I have set the new network up in Airport Utilitly and the Extreme and Express dont always work. More often than any other issue is the the Internet is flicks from green to orange. The internet ethernet cable I plug into the Extreme clearly feeds internet but as soon as I plug it into the base station I get nothing (im assuming there may have been nothing wrong with my netgear router now and a problem with my connection).
I have reset the Extreme and Express many times and it works for a while (sometimes), but then I try to connect my ipad/iphone or smart TV to the network and it drops out. All products are apple apart from the TV. So frustrating as I never had these problems before this particular powercut!
Here are some screen shots of my network:
1) This is with the internet plugged directly into the macbook
2) This is with the ethernet cable (which feeds the internet) plugged into the Extreme (and etherent cable from extreme into mac book otherwise you sometimes can see the base stations). With this picture I couldnt access internet or base stations settings.
Sometimes however the system does work and then suddenly drops out. I have checked my DSL modem/router which feed the internet and there are no problems with it. It doesnt seem consistant at all. How can it suddenly work then drop out? This happens as soon as I connect another device like my ipad as well, then I have to reboot all over. I cant imagine that every device in my house are broken! My network has gone to pot!
Sending this with the ethernet plugged into my mac book direct haha!
Would be most grateful if anyone can help!

Cannot connect 2 macbooks to the internet through AEBS?

Hi,
I have 2 Macbooks, Airport Extreme Base Station & a 320T D-link router. My ISP is plusnet who uses PPPoA settings on the d-link router. So i have set the router up and when i connect it to the Macbooks directly via ethernet i can access the internet. But once i connect the d-link router to my AEBS i cannot connect to the internet? Both Macbooks can see the base station but they cannot access the basestation. If i put the base station in bridge mode the light will go green and one can connect to the internet but obviously i want both to connect! I am unable to put the d-link router in bridge mode as my ISP does not support this as the router will only work on the PPPoA settings to retrieve the IP's etc from Plusnet. I have spent countless hours on the phone to apple and changing settings but to no success. I have spent more money to buy the d-link router as i had a netgear D111MP router previously but i read that it was a poor product to go with the AEBS. So the issue does not lie with the router?
If anyone can help i would appreciate it so much as this has become so frustrating!
Many thanks!!

Thanks Duanne, problem is that i have bought the netgear DM111P and the d-link 320T and found out that they cannot work for some reason. So i have spent £70 on both modems/routers plus the £119 on the AEBS. It's just a bit annoying when i have spent a lot of time and money on something which i was hoping would be as simple to set up as all the other apple products.
By the way i'm not having a go even though it sounds like it! The main thing on my mind is to get my AEBS working. Would it be possible to advise me on a router that will work well with my AEBS to solve this issue i am having? Also one that can use the PPPoA settings from my ISP? This would be greatly appreciated as i don't want to go out and buy another router and find out it doesn't work.
Also if i get a router that can do this what would be the setup of my AEBS?
Thank you for your time on this!

Airport Express not connecting to the internet via cable modem

Hi. I need help. I just bought an airport express to get wireless internet and airtunes. I connected everything and ran the airport utility. Everything is good, so it says. I can play music through my stereo using airtunes, but when I try to get on the internet I get nothing. My macbook recognizes the network, but I can't load any pages. I've tried unhooking the ethernet from the express and unplugging the power from my modem, then plugging my modem back after about 30 seconds, then reconnecting the ethernet to the airport after another 30 seconds but still, nothing.
Does anyone know what I'm doing incorrectly? When I connect my macbook directly to the modem via ethernet I'm on the internet just fine. Thanks!!!!

Do you have the Express setup to distribute IP addresses?
If you do, you might turn it off in the Airport Utility.
Also check you IP address on your MacBook.
Make sure it is not self-assigned or something different than what your provider (cable modem) usually assigns you...

I am connected to a time capsule both wirelessly and through ethernet...and state of the time capsule is solid green...the internet however doesn't work...The internet works fine when directly connected to my macbook pro but it won't work through the tc

I have deleted time machine preferences...restarted the modem a bunch of times, restored time capsule to it's original settings...after I first set it up in Airport Ulitity its shows a page quickly that states there is a internet problem, but the page quickly goes away before I can read what it says exaclty and states the internet connection problem is resolved...
However it's not resolved, I'm also having trouble doing a back up to my time capsule...I recently purchased a new macbook and retrieved/restore what was on the time capsule to the new computer...that worked fine...wireless worked fine...however when I tried to back up the new macbook...it would faii stating that there isn't enough room on the TC to do a back up...
I didn't end up keeping the new macbook, I was just using it/trying it out while my current macbook pro was being repaired (logic board)
Ever since I got my current macbook back from repair...my backups have failed due to their not being enough space to perform the back up...in the past the back ups would happen and old back ups would be replaced...
I think this has to do with my current computer having a new name after the repair..."Adam's macbook pro 2" vs "Adam's macbook pro"
The internet was working fine wirelessly through the TC a day ago, but it wasn't allowing my other laptop that was connected via ethernet access to the internet...I had a self assigned IP address error then...I don't have that problem now, but it's not transmitting internet at all...even though it's in a solid green state.
I have no problem completely wiping out my TC including the previous back ups on it...just don't know how to go about it...I have restored it to factory settings a bunch of times and created the network from scratch...just hasn't fixed the issue
Is there more prefences files I should delete

If the modem is also a router, either use the modem in bridge and run pppoe client on the TC.. that is assuming ADSL or similar eg vdsl. If it is cable service.. and the modem is a router, then bridge the TC.. go to internet page and select connect by ethernet and below that set connection sharing to bridge.
Please tell us more about the modem if the above gives you issues.

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.

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.

My macbook pro will not connect to the internet via wifi or ethernet connection

Hey guys just a few days ago randomly my 2011 macbook pro stopped connecting to the internet. My girlfriends macbook still connects fine as well as both of our iphones and my tv. Under network in system prefrences wifi is yellow and says self assigned ip, however ethernet says that it is connected with a green light but safari nor any other internet using applications will work. I even tried downloading google chrome from my girlfriends mac book and moved to my computer via flash drive but still no go on the internet. Please help me.
-thanks

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then either copy or drag it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}'
Copy (command-C) the selected text to the Clipboard. Then click anywhere in the Terminal window and paste (command-V). Post the lines of output (if any) that appear below what you just entered. You can do that by copy-and-paste as well. Omit the final line ending in “$”. No typing is involved in this step.
Step 2
Repeat with this line:
sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|edu\.mit|org\.(amavis|apache|cups|isc|ntp|postfix|x)/{print $3}'
This time you'll be prompted for your login password, which you do have to type. It won't be displayed when you type it. Type it carefully and then press return. You may get a one-time warning not to screw up. You don't need to post the warning. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
launchctl list | sed 1d | awk '!/0x|com\.apple|edu\.mit|org\.(x|openbsd)/{print $3}'
Step 4
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of every login item' 2> /dev/null
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

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.
