Connecting iMac to Network via Ethernet Cable and Airport Express

I've tried reading through the various posts to solve this and haven't had any luck. Any help is deeply appreciated.
I have an Airport Extreme as my main 'base' for our wireless network. I purchased an Airport Express today with the notion of using it to extend my network in the following way: I want to connect an iMac and a printer to the Express (using Ethernet and USB cables respectively) and have the Express serve as a remote for the Extreme base. I have found a number of websites saying this is possible, but none explain how to. I tried the WDS option, which failed to work. I later saw posts here saying that was not the optimal scenario. I'm afraid the 5Ghz/2.4Ghz settings combined with Airport ID addresses has pushed me past my competency!
Thanks in advance for your help and a festive St. Patrick's Day!

Temporarily, power down the AirPort Express and concentrate on the AirPort Extreme to make sure that it is functioning correctly, can get an Internet connection, etc.
A complete power cycle of the network is often useful when you have been making changes. Power everything off, order is not important.
Wait a moment, (or wait 5-10 minutes if you have cable modem), then power up the modem first and let it run a moment by itself. Then power up the AirPort Extreme the same way.
Check your settings using AirPort Utility - Manual Setup
Click the Wireless tab just below the row of icons
If the Wireless Mode setting is "Create a wireless network", make sure there is a check mark next to "Allow this network to be extended"
Note the exact setting for Security that is being used
Update to save any changes
Post back when the AirPort Extreme is functioning correctly as above and we'll tackle the AirPort Express

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.

Connecting to Server 2003 via Ethernet vs Routher/Airport Express on PB-G4

A co-worker at the non-profit arts group where I volunteer can connect her Powerbook G4 to our Dell server and get to network drives via Ethernet fine. Also has access to Net finee via Safari through server to cable modem. When connected to the lINKSYS wireless router to the server, the network drives are not available. A Dell laptop works fine in this configuration. What is causing Finder not to see the Dell Server network drives when connected via the router, but to see them when connected via E'net??

Thanks, but one of my questions is related to what it says in the documentation as follows:
"When the base stations receive power and a network connection over the WAN port, the USB port is disabled. You can connect the Ethernet LAN port to a computer or other Ethernet device, but power does not travel to the Ethernet LAN port. "
So if my set up is as I describe is my USB port disabled? (does my network connection receive power/connection over the WAN or the LAN?

Out of the blue, my ITouch is unable to access my wireless network ONLY when my PC has been turned on (PC is connected via Ethernet cable, and has no wireless capability as far as I know). What gives? It works fine when the PC is off.

Out of the blue, my ITouch is unable to access my wireless network ONLY when my PC is on (the PC is connected via Ethernet cable, and has no wireless capabilities that I know of). What gives? When the PC is turned off, everything is totally fine. I\m stumped.

Does the iOS device connect to other networks?
Does the iOS device see the network?
Any error messages?
Do other devices now connect?
Did the iOS device connect before?
Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on your router
.- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- Wi-Fi: Unable to connect to an 802.11n Wi-Fi network
I suspect a problem with your router. Try changing the security. First use no security as a test.
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem and it does not connect to any networks make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

I CANNOT PRINT FROM MY IPHONE 4 TO MY BROTHER 8890DW PRINTER WHICH IS CONNECTED TO MY TIME CAPSULE/NETWORK VIA ETHERNET CABLE???

Why can’t I print from my iPhone 4 to my brother 8890dw printer which is connected to my time capsule/network via ethernet cable??? My iPhone does not even locate my printer,even though I have no problem printing from my Mac to the same printer.

Typing in all caps indicates shouting, is considered rude and is difficult to read. Many simply do not read such posts.
You would need an airprint enabled printer or an app that proides printing function.

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 transferred files and photos from MacBook to iMac via ethernet cable and using migration assistant. However every time I transferred, it created a separate user and it transferred all files and photos again and again. So now I have 3 users accounts ?

I transferred files and photos from MacBook to iMac via ethernet cable and using migration assistant. However every time I transferred, it created a separate user and it transferred all files and photos again and again. So now I have 3 users accounts with all files and photos saved 3 times on same iMac !! Any idea how to avoid this ?

Yes, you ran into a very understandable problem.
When you use Migration Assistant, it cannot over-write the account that you happen to be using at the time. Upon migrating accounts, it will tell you that it is going to create a new one, but that message is easy to miss.
If you have three identical accounts, log in to the account you want to keep, and delete the redundant ones in System Preferences > Users & Groups.
Now that you know, the easiest way to migrate accounts is to use Setup Assistant when you first get a new Mac. That eliminates any possibility for this to occur, but most people are so eager to use their new Mac that they elect to migrate later.
That's OK too, but in that case you would want to create a temporary account whose sole purpose is to run Migration Assistant so that you may migrate your old one with an identical name. Be sure to give the new account Administrator privileges. When that finishes you would log in to the newly migrated account, and delete the temporary account.

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.

I have a 3rd party hard drive with movies on it ,it is connected to my airport extreme. The AE is connected to my tv via ethernet cable. Can I stream my movies to the Tv ?

I have a 3rd party hard drive with movies on it ,it is connected to my airport extreme. The AE is connected to my tv via ethernet cable. Can I stream my movies to the Tv ?

Not without a player..
The AE is a dumb file server.. the hard disk you plug in is an even dumber hard disk.
There are no smarts in this setup.. not even DLNA. So the TV would have to be an extremely smart one to read raw files on a network drive.. none do that I know of.
A solution is WD live TV.. it can read files from just about any file source on network and play them to the TV.
Nothing apple makes will do that.. ATV is a streamer not a media player. Everything in the Apple world is tied up with itunes. So you must have a computer running itunes to use it.
You can download a more generic player for ipad, and put that as part of the network.. but you still need ATV to display the video.

Sorry, but it is not possible to "extend" the Guest Network using either wireless or an Ethernet connection.

Connect HP laserjet 2100TN to Imac 10.8 via ethernet cable

I want to connect my old HPlaserjet 2100tn to my new imac os 10.8 computer. Apple and HP say it is compatible. The printer was hooked to my G5 via the ethernet cable and worked fine. There is no usb hookup for this printer that I can find.
I am able to find an IP address for the printer via network, the print/scan finds the printer and adds it, driver is in place (after some searching from apple) and everything looks good. Only problem is it does not print. Get error message saying the printer doesn't exist and some other similar messages.
Have spent way too much time talking with apple and HP andit apears I know more about this than them anyway. It's too big a challenge I think.
Do I need to run through my router (old airport base staion that works just fine...looks like a spaceship) which has a port for another ethernet cable? My internet is wireless, this printer in not wireless capable (IR though..old), but can I hook it in and operate that way without srewing up my wireless internet?
Come on...someone has the simple answer to this question. Just want to use my old postscript laser printer every now and then.
Thanks for your help.

This may not help at all, but I have an HP Color LaserJet 2605dn, and one day it just stop being part of my network, as far as I could tell. Would not print, could not be found on the network, even after manually putting in network information.
I reset the printer. I did a NVRAM initializer and a Super NVRAM initializer. I found out how from the service manual for the printer.
I the setup the printer again, like I had taken it out of the box new.
Runs fine. Prints, is found on the network, can use the web based software it has in it.
Maybe this may work for you.
Good Luck.

I am having difficulty connecting apple tv to our network via ethernet cable.

I am trying to connect to an apple tv on our office network. It seems to pick up the network configuration but doesnt connect when I turn on home sharing. We have a proxy server for connections to the internet so I dont know whether this is the show stopper or something else like incorrect setting of date and time. I thought I could set up and use the apple tv without a connection to the internet. Any advice would be appreciated. If an internet connection is absolutely necessary may be I could set up an Airport that talks to our proxy server.

COMPUTERS SETTINGS means AppleTV is not accessing the Internet network.
By "changing the lead" I assume you mean you've made certain you are using a proven / known working Ethernet cable and you've also attempted, unsucessfully, to connect via WiFi ?
If those things are true it sounds like you need to consult the school network administrator for onsite assistance.
I ran into this problem once but did not have time to work through it. I will duplicate portions of your problem today to see if I can better resolve your question

Connecting HP Laserjet 500N using ethernet cable and router

I had my HP Laserjet 5000N connected to my wireless router via ethernet cable. It worked fine. But then I changed routers and can't remember how to reestablish the connect.
Can anyone help?
Thanks

no problems.
There is a priority order when multiple networking interfaces are available.
Ethernet is higher than Airport in the order.
If both ethernet and Airport interfaces are connected to the network, then ethernet becomes the primary networking interface.
If nothing is plugged into the ethernet port, then Airport will get control.

Deskjet 6940 connected via ethernet cable to Airport, will not print

Hello,
I used to run my HP Deskjet 6940 printer using a USB connection. I recently installed an Apple Airport Extreme so I can print wirelessly. As required, the printer is now connected to the Airport using an ethernet cable, and the green network light is on. On the advice of an HP rep via telephone, I uninstalled all older HP software and reinstalled HP software downloaded from the HP website.
When I try to add the printer on my "System Preferences," it opens a panel that contains the following options:
Protocol: Automatically chooses "line printer daemon--LPD"
Address: Blank but allows me type in the assigned IP address
Print using: No idea.
Two more things: when I open HP device manager, and select 'configure a networked printer, all network confirguation info appears fine but the manager does not allow me to "apply" it. Not sure if this is important but no printer utilities show up in my utlities folder since the new software download. Thanks.
This question was solved.
View Solution.

It looks like you are running a Mac.
First of all, the driver for the Deskjet 6940 is built into the Mac OS. You really didn't need to download extra stuff from www.hp.com (sorry about the bad advice).
Next, let's verify that the printer is on the network. From Safari, select Bookmarks, Show All Bookmarks. Select Bonjour from the left hand pane and verify that the Deskjet 6940 appears on the list of devices found on your network.
Next, follow these instructions to reset the Mac printing subsystem: http://support.apple.com/kb/HT1341
Now add the printer from the Print & Fax applet under System Preferences by pressing the [+] button. The Deskjet 6940 should be listed as one of the Bonjour kind of printers. Select it and then press Add.
I think that should do it.

Internet through wifi while connected to different network by ethernet cable

HI,
Is there a way for my iMac (2012, OS10.8) to take internet from wifi connection (tethered to iPhone 4S) while it is connected by cable to a router that does not have any internet connection?
The reason for this strange situation is that the telephone wires coming into the house was accidental pulled off, so I cant get internet through the telephone wire. I have to rely on 3G through my phone. I just bought Sonos Play 3 and Bridge, and they wont work unless their firmwares are updated. In order to do this, the iMac has to be connected to the Sonos (either by wifi or ethernet cable) and the internet at the same time. Since I am using wifi to be tethered through my iPhone to the internet, I have to use ethernet cable to connect to the Sonos gear. Whenever the ethernet cable is connected to the iMac, the iMac wont receive internet date through the wifi/tethered connection.
Any ideas?
Thanks,
Henry

Thanks. I therefore have a problem as I cannot connect my ipad to the Apple TV. When trying to connect via Airplay my other apple tv appears (that is connected only via WiFi and that connects OK) but the Apple tv connected via the Ethernet does not show. I have looked at all the settings on both apple TV's and the only difference I can see is one is connected via WiFi and the other through Ethernet cable. Any ideas on what I need to check out?
