Ethernet connection and airport failure

I'm studying abroad in Madrid, Spain, and I'm having difficulty with my internet access. On campus, the IT director put in the airport location and password, and it won't log on. It says "failure to connect." Other Macs in the building are working fine, but mine. I noticed that when I open 'Internet Connect,' the status under Airport says "Computer to Computer." Also, at my residence, my ethernet connection is not working. I plugged in another Mac into my port, and it worked fine. I tried putting in the TCP/IP for Ethernet manually (IP Address, Subnet Mask, Router, and DNS servers), without success. I always get a message reading "unable to find host." Any help would be greatly appreciated!

Luz, talk to the IT staff, the base stations that you are using need to "know" your PB's card address, in the airport utility, how many base stations can you see? Also make sure that in the airport setting, you have removed the "allow this computer to create networks" tick, this can cause havoc in some networks and get your machine booted off.
best wishes

Sharing Ethernet Connection Through Airport

Is it possible to share your Ethernet connection through airport so that two computers can connect to a single connection without the need of a wireless router? I know that this is possible on XP, but I am somewhat new with OS X and cannot seem to figure it out. Does anyone have any suggestions?

Open the Sharing preference, click on the Internet tab, select the connection to share from the drop down menu, then check the ports that will share the connection.
You will find additional info by selecting Mac Help from the Finder's Help menu and searching on the appropriate term.

It seems like Ethernet backup and Airport backup goes in different ways

Since one month a go, I've been having problems with Time Machine backup over Time Capsule.
When I run Time Machine through Ethernet, there is no problem. Fast and clean. In the Console there is not any error message.
I unplug ethernet cable, start airport, and in the next copy appears: "Bulk settings atributes failled", several times. Few backups after it will appear problems with a "file path" and few after will appear "deep traversal".
I plug the Ethernet cable, disconnect airport and I forced to re-index the image bundle. Few backups correct with Ethernet. Unplug ethernet, connect airport, and again the same history.
It seems like Ethernet backup and Airport backup goes in different ways.
Permissions are corrected and there is no problems in any disc with First Aid.
¿Any idea?. Thanks in advance.

I am having the same issue. I have three layered elements as three columns in the body of the page. When I add the farthest right element it pushes the other left elements to the bottom of the page. There are aren't any other elements on the page.
Is this a CSS issue? I thought about exporting to Dreamweaver and fixing it there but would like to take the easy route first.

I have a Mac pro with osx ml in a Ethernet connection and a apple tv with a wireless, there is no way I can see the airplay in my Mac pro

Mac Pros don't support Airplay. Only some post 2011 Macs do, MAc Pros aren't amongst them.

You could try Airparrot software as a workaround.

Solution for Apple TV 2, Xfinity router, Ethernet connection and Home Sharing

I have read over the past week the problems people have been having configuring their Apple TV and Home Sharing. I was experiencing the same issues as others....until tonight. I finally got it to work with an Ethernet connection. Previously, I was only able to get it to work via wifi and home sharing would drop after awhile.
1) Xfinity router settings. Like others I was suspicious if the Xfinity router was causing the issues because of the separation between wifi network and Ethernet network. It's not the router problem. I disabled the firewall. Enabled port forwarding. Gave a static IP address to the Apple TV. Added forwarding of ports
   123 TCP
    3689 UDP (all other support says this should be TCP but searched through and found a thread that suggested changing to UDP...this was the key)
    5353 UDP
    80 TCP
    443 TCP
    53 TCP
DMZ is off
Device discovery is disabled
Port triggering is disabled.
The wifi is setup and functional using DHCP. Lease time is 1 week.
RESET ROUTER AFTER ENTERING CONFIGURATION.
2) Mac computer. As of this posting the latest version of iTunes installed. Latest Safari version. All programs updated. Turned on Home Sharing. Turned off firewall. Gave Mac a static IP address. Set Mac for hard drive to never sleep. Set monitor to sleep after 15 minutes. Set date and time to automatically find based upon time zone. ( Apple TV needs to be set to the same time zone as computer and set to manual). Enabled file sharing amongst users on Mac.
3) Apple TV. Ethernet connection. Configured TCP/IP to static IP address I configured on router for the Apple TV. Turned on AirPlay. Set date and time to manual and set as the same time zone as the computer with iTunes. Turned on Home Sharing. Using latest version of Apple TV.
Once the router was reset ( not restored and not just resetting the wifi. A complete router reset), the Apple TV found my iTunes library. It's been running now for over an hour and no drop in the home sharing. Working beautifully. I will be testing in the next couple days allowing the Apple TV to sleep, turning the firewall on the router to a minimal setting to see if it changes anything.
Just tested the AirPlay from my iPad 2 to the Apple TV while the Apple TV is connected via ethernet connection and it works. At this point it appears that the setup is correct and complete with no errors.
As a side note, the Ethernet connection between my router and Mac is via commercial devices using the power outlets as the wiring.
Hope this helps many of you that were/ are struggling to get this to work like I was.

spma3,
Appreciate your further message. As you say "it's not fixed", but at least your solution appears to be a viable workaround!
My Cisco RVS4000 Router will permit me to forward ports for up to 15 applications. Of these, thirteen already have default entries added, although none of these are presently Enabled. For example, here's just 2 lines...
Application           HTTP        NTP
External Port          80           123
Internal Port           80            123
Protocol                TCP          UDP
IP Address            No entries at both
and the Enabled box for both is unchecked. In fact none of these 13 possibilities is Enabled.
To do what you are advising, I would need to...
1) Enable the above Port 123 entry, changing it from UDP-->TCP.
2) Add new entries for 3689 UDP & 5353 UDP... using the two free slots at the end of the table.
3) Select three of the default entries, and reconfigure them for 80 TCP; 443 TCP; 53 TCP, all as per your guidance. And Enable them.
Now, my present setup here has...
1) My PC is wired straight to Port 2 of the Router, and has a Static IP Address set.
My new ATV2 is hard-wired into the same subnet, albeit thru a series of switches, and again a Static IP is set. My understanding is that hard wiring an ATV automatically disables its WiFi.
3) My wife's iPad2 is set for DHCP, so it can pick up an IP Address when on the move. It connects into the LAN using one of two WAP4410N Wireless Access Points. Ch-1 & Ch-6, with same SSID and security stuff set up on both. The WAPs in turn are wired in, again with Static IPs set. So depending where she is in the property she can connect with excellent signal strength, reaching the ATV2 by WiFi+LAN.
On the Router DMZ is OFF, Port Range Triggering has no entries, nothing is Enabled, so is OFF. No idea about Device Discovery!
Home Sharing is ON for the PC, ATV2 and iPad2, with the same Apple ID/Password set for each. It does work, just not consistently as it should.
So to fully implement your idea, all I need to do is to enter these details. But I am unclear which IP Address I should put in at each new Single Port Forwarding entry field. Certainly not the iPad2, as its DHCP allocated value will change. Is it the ATV2 or the PC? Not sure, please clarify.
BTW, I have no plan to deactivate my AVG Firewall on this PC. It is happy to pass all traffic related to iTunes, so cannot see this as a factor. Time zone same on all equipment.
I tried with just 3689 UDP and 5353 UDP yesterday, and things were definitely better. I used 192.168.20.227, the IP Address for the ATV2.
Look forward to your answer.

Can I use Ethernet for Internet connection and Airport express for printer

How / can I use Ethernet for Internet connection and use an airport express to set up wifi for printer and Apple TV?
Macbook Pro. OS X 10.9.4

I've never tried it, so I don't know what the results will be.
However, you can move Ethernet to the top of the Services list in Network System Prefs which will cause it to be the Internet source. There is a command in the gear menu to set the Service order. However, after thinking about it, if there isn't an internet connection via Wi-Fi, it might automatically drop down to the Ethernet connection.
Then, you can set up your Wi-Fi so that it doesn't connect to the Internet, as Linc stated. How to do that would be dependent on the Router.

ITunes 10.6.3.25 on ethernet connection loses airport express speakers but iPhone 4 airplay works

Hi,
I have started experiencing a problem this past week (Aug 2012) that I see sometimes reported here. When I run iTunes 10.6.3.25 on a Win7 machine that is connected by ethernet to my router, the airport express speakers would regularly disappear. I can always connect to these airport express via airplay from my iPhone 4. In fact when the airplay speakers disappear from iTunes on the ethernet-connected machine, I can reliably make them reappear by turning on the Music app on the iPhone. But after a while the airplay speakers would disappear again. On a Win7 laptop connected via wifi to the network the same version of iTunes seems so far not to exhibit the same problem.
Has anyone discovered what the underlying problem is or found a solution?

I ran into the specific problem in another thread. There are more than 100 connections from the apple TV's to iTunes. You can do a netstat -a (windows or Mac), and verify the problem. iTunes is smart enough to stop allowing more than 100 connections but stupid to allow the ATV to create so many connections.
Now for what you really want! Set all of your ATVs to wifi only. Even setting the iTunes host to wifi might help also. I think that wifi is more unreliable, and forces connections to drop, keeping the count under 100.
I also turned off ip v6. That could help you also. I originally had problems on a Mac mini, and built a windows 7 box to try to fix the problem. The wifi trick worked on both platforms. Several of us have bug reports into apple. I have a wired house also, and am very angry to NEED to use slow wifi to overcome this problem. The ATV gen 3 has been able to keep up with 1080p over wifi, so it doesn't hurt too much. What really hurts is spending over 40 hours troubleshooting this bug.

More ethernet connections for airport express

I am looking to hook up an ethernet switch to an Airport Express to provide additional ports to connect devices such as a printer (which doesn't want to function consistently in Wi-Fi mode), and possibly a Blu-Ray player. Any problems with my thinking here?

As long as you have verified that the Ethernet port has been enabled on lthe AirPort Express, you can connect an Ethernet switch to the Express to accommodate additional Ethernet devices.
Keep in mind that your "Ethernet" connections will only support as much bandwidth as the wireless network allows. This will likely be far less than a direct wired Ethernet cable connection from the main router to the Ethernet devices.

OR
Networking with a Windows PC
This document provides an overview of options for connecting a Macintosh to a PC or other computer on the same network. In this article a "PC" is a computer using Microsoft Windows with an AMD or Intel microprocessor.
Summary
There are several ways to connect to a Windows PC. First, you must physically connect the two computers to a network, which may be as simple as a single cable connecting the two. Once this is done, you must start some type of sharing (or file service) on at least one of the two computers.
The computer that is sharing is known as a server. The computer that connects to it is called a client.
To connect, the client computer just needs an application program that can connect to the type of service being offered. Sometimes this application is a built-in part of the operating system, such as the Mac OS X Finder or Windows file browser.
When you connect two computers together, it's useful to understand what is meant by "client" and "server." Though the idea conveyed by these terms is simple and generally consistent, there is an important variation on each: Any computer that offers a service is a "server" in that context. However, the term is also used to describe a computer or operating system that has been designed expressly for that purpose, such as Mac OS X Server. In addition to describing the computer, "client" is also used to describe the software used to connect to a particular service. A Web browser, for example, is an HTTP client.
For greatest convenience in a work environment, you may want everyone on the network to be able to freely connect to each other's computer. This would mean you need to achieve bi-directional service, in which each computer can both share to and connect to another computer. In the example of a Mac OS X 10.2 computer and a Windows 2000 computer, this is as simple as turning on sharing at each computer. In other examples below, additional software may be required to achieve this.
Making a physical connection
The physical components of an Ethernet network are compatible with computers that use many different operating systems--such as Mac OS, Microsoft Windows, Linux, and UNIX. You can connect all of these computers to the same physical network, which may be wired or wireless (AirPort, for example).
Making a service connection
Services are designed for various tasks, such as transferring files, webpages, or print jobs. Common examples that you may use are:
AppleShare (also known as AFP, Personal File Sharing, Apple File Service)
File Transfer Protocol (FTP)
Hypertext Transfer Protocol (HTTP, used primarily for webpages)
LPR (Line Printer Request, common for printing)
SMB (Windows file sharing)
To get two computers on the same network to communicate with each other, you must identify a client-service relationship that they have in common. When you have computers using different operating systems on your network, it may help you to list the services offered by each operating system. You could then list the services each operating system can connect to using its built-in client software, such as the Chooser (Mac OS 9), the Connect to Server command (Mac OS X), the Windows file browser, or a Web browser. If you identify gaps in the desired client-service arrangement, third-party software may provide the missing components, thus adding possibilities that do not exist "out-of-box." Here are several examples:
For each example scenario, other options exist. Before you can connect, a service must be intentionally turned on at the computer that offers it. For more information, see the documents linked below.
Connect Windows 2000 to Mac OS X 10.2, 10.3, or 10.4
Mac OS X 10.2 or later offers Windows File Sharing (SMB). Windows connects to SMB.
Connect Mac OS X to Windows 2000
Windows 2000 offers SMB service. Mac OS X 10.1 or later can connect to SMB service in the Finder.
Connect Windows 2000 to Mac OS X 10.1
Mac OS X 10.1 can offer FTP service, found in Sharing preferences. Windows 2000 can connect using any standard FTP client, which includes many Web browsers.
Connect Mac OS 9 to Mac OS X
Mac OS X offers file sharing service (AppleShare). Mac OS 9 can connect to AppleShare from the Chooser.
Connect Windows 98 to Mac OS 9
Mac OS 9 can offer HTTP service, which can be used to transfer either Web pages or files when configured properly. Windows 98 (and many other operating systems) can connect with a standard Web browser.
Connect Mac OS 9 to Windows 98
Windows 98 offers SMB service. If you install third-party SMB client software on Mac OS 9, then it can connect to SMB.

Sharing ethernet connection with airport card from ( iMac 17" intel)

I have recently upgraded from a 800 15" iMac to a new 17" intel iMac - before the upgrade it would share the ethernet connection to the internet with sharing and broadcast the signal to my FW800 powerbook ( or any other mac in the house ( no problems)
Now with the new Imac set up I enable sharing ethernet connection to computers using airport ( same as before) I can see the computer ( sharing the connection) in the airport menu of my FW 800 PB - when I try and connect I get an error message ?
Looking for any tips or direction? I searched this forum ans apple support pages and did not find an answer... PB = OS 10.3.9 - Imac = OS 10.4.5

Hey thanks for the welcome!
The error message said " there is an error in connecting to ..."
OK ( after just checking it again) go figure - I turned off sharing ethernet connection to computers using airport on the iMac - and turned it back on and voila! I am now connected using the PB - ??? Must have been a reset issue?
lets see if this is a solid connection...
Thanks for the fast reply!

Ethernet Connection and Receive Airtunes?

Hi
Here is my set up:
- iMac connected wirelessly (g) to router
- router connected by ethernet (via Homeplugs) to Apple TV
My problem:
I want to keep the ethernet connection to the Apple TV because syncing is quicker (I guess the distance between the router and the Apple TV is too long to be able to sync effectively wirelessly). However, I also want to be able to use the Apple TV as an airtunes speaker from my iMac. This doesn't seem to work. Is the fact that the ethernet cable is plugged into the back of the Apple TV stopping it from receiving the signal? Can I force the signal to go to the router and then down the ethernet cable?
Any help appreciated.
Thanks
Spencer

The problem is not the ethernet and wifi mix, you should be able to use the tv as airtunes speakers. I'd take a look at your network settings as a possible cause.

Ethernet connection and 'shared' option in finder window!!!

I am relatively new to mac and everyday I see something that I don't understand, like the other day I connected to internet using ethernet cable and 'shared' option appeared in finder window with all kinds of people and devices listed. It never happened when I connected through wireless. What does it mean? Are other people able to see my computer and the content on it? Any explanation would be appreciated.
Thanks

Hi
It's either a PC or some other Hewlett Packard device connected to your network or on another network (probably wirelessly) you're connected to. It's in the Shared section of the Sidebar because it's either broadcasting itself using Bonjour or more likely NetBios. You can choose to not see this option by disabling it in the Finder Preferences.
It's also possible it's your router/gateway/wireless access point.
If you've not enabled personal file sharing and you're not in the habit of handing your account password out to all and sundry, there's nothing to worry about.

Lightening strike killed Ethernet connection and more?

Lightening killed my ethernet connection. I saw a post that said a 3rd party replacement board would do. I installed it (Sonnet's Presto Gigabit 10/100/1000 PCI) and I still don't have a connection. Internet provider's modem talks and my Mac 10.4.2 sees the new board but no connection. Reloaded OS to not avail. Everything else works fine. Any advice?

I too read the various reports on xlr8yourmac about the NetGear GA311. My husband had purchased this card to try in my son's PC that had lost its NIC card in the lightning storm as well. It didn't solve the problem on that machine. I found another post on Amazon by a reviewer who said he is an Apple Certified System Administrator. His report was that the GA311 should work in Tiger 10.4 and later without a driver.
I've now tried the card in my G4 Sawtooth, similarly impaired by the storm, and after multiple, varied attempts to set it up with the Network preferences am unsuccessful. Network preferences recognized that the device was in the PCI slot and attempted to set it up. It just can't seem to complete the task.
Now I'm wondering if there may be some other related damage on the machine that would affect its ability to connect to the Internet. Does anyone have any ideas about that? What other components are part of that capability on the G4? Can I try replacing an additional component while also replacing the card?
Thanks for reading this post and sharing your feedback! I really want to get my wonderful G4 fully operational again. I have my new MacPro up and running now and its wonderful, but it won't run the majority of my Classic compatible software, like QuarkXpress 5, Flash 5, etc. I would like to continue having access to those programs.
