After setting up my brand new Airport Express 802.11n and accidentally using it to connect my iMac to the network...my iMac no longer connects through Ethernet? Any ideas...I have tried everything without success!!
I have been using Apple technology for about 10 years starting with 1st generation iPods and our house now includes a 5 year old iMac, all versions of iPods and touches, Apple TVs (both generations) and most recently an iPad 2. I have always told family and friends that Apple technology just works. Unfortunately that stopped today. I bought a new Airport Express 802.11n to use for AirTunes around my new pool. I set it up from my iMac and accidentally used it to connect my iMac to the network for a short time. Now I can no longer connect the iMac to the network using a hard wired Ethernet cable. I have tried resetting everything possible, from hubs to routers to the Mac itself and it just will not connect to the network through Ethernet any longer. I am now a very frustrated Apple user especially when the support site says I can't use the fast path support because my product was manufactured 5 years ago...I just bought it at BestBuy yesterday. All other computers and itechnology in the house are connecting via wifi and Ethernet without any issue except from my new iMac boat anchor. Anybody who can help me??? Thanks
John, thanks for the email so quickly.
I too hope I haven't tried "everything" either but I am reasonably technical. I had done what you suggested to do before but I did both again.
Ethernet is yellow in the left side bar. In the right pane it's status says Connected but then below it says "Ethernet has a self-assigned IP address and will not be able to connect to the Internet."
I have tried the assist me menu and Network Status has Ethernet Green, Network settings Yellow, ISP Green, and Internet and Server Red and Failed for both. I have turned things off and on, checked cables, deleted all locations and tried restting them up but to no avail. I even disconnected everything and connected the mac directly into the cable modem itself and the thing still will not connect.
Thoughts???

Unable to Connect Using New AirPort Express 802.11n
My mom purchased an AirPort Express 802.11n wireless router (AX) and I, as the designated "technology guru", was tasked with setting it up. Unfortunately, I am having problems out of the box.
When I connect it to the wall, it is found by AirPort Utility, but when I try to set it up, it is unable to connect to the wireless network. ("An error occurred joining the selected wireless network." "An error occurred, close the configuration window and try again.") This is annoying because I have an older AX and it was true to the "it just works" Apple mantra. It is also annoying because the error message has a comma splice.
Feeling pretty proud of my "technology guru" title, I come here to see what I could be doing wrong. I try connecting the computer directly to the router via ethernet cable. With this, I am able to setup my wireless network. I am still not able to connect to it. Additionally, once the AX has been configured, the AirPort Utility can't find it.
I tried updating firmware to 7.5.2. I've tried downgrading to 7.3.2. I've tried hard resets, soft resets. Every tip I could find I have tried. Please help. My self-confidence is wearing out.
Is it time for a call to Apple or a visit to the Apple Store?Are you trying to configure the Express to "join" the wireless network?
If yes, the message you are receiving is likely an indication that you do not have the correct security settings selected for the Express. Unless the security settings between the wireless router and Express match up exactly, the Express will display the error that "an error occurred, etc".
The easiest way to confirm if you have this problem is temporarily set the main wireless router to "no security" and try to connect the Express that way. If you can connect, then you know that it is a security issue.
Please tell us the exact setting for security that the wireless router there is using and we'll try to give you some more ideas.
The Express will connect. It's just a matter of finding the right settings.

Airport Express 802.11n and Dlink N wireless router
Problem: Unable to connect Airport Express N to Dlink N router
I have a Dlink G router and an Airport Express G in connected to that wireless network for a couple of years. I bought a new DlinkN router. I have been unable to connect the Airport Express G. I read many posts on this topic and concluded that I needed a new Airport Express N. I got one. I could connect both Airport Express G and N to the Dlink G router.
I tried to connect the Airport Express N to the Dlink N router. I get to the stage where it says the settings on the Airport have been successfully changed and to wait for the Airport Express to restart. The amber light keeps flashing. It never goes green. I have reset the Dlink router and the Airport Express N many times with no success. I even tried to connect the Airport Express N to the Dlink N router with wire and tried to reset it. It did not work either. There appears to be some problem connecting a Dlink N router to Airport Express N.
Does any body have a similar prolem or a solution?
Thanks for any help. In the mean time I will keep using the Dlink G router which works fine.
Raj WarreirMore than likely the problem is with the Dlink N router. I have no problem connecting a D link g router and Airport Xpress G and N. I had to replace the Dlink N with the G due to the above issue.

I recently switched from LinkSys to Airport Express 802.11n. I love it...but now I my Wii can't see it so I can stream NetFlix. I have found MANY discussions on line about this...but it's still not clear to me. Anybody have a step by step way to fix this? Thanks! Jim Matherly
Well, the Airport Express is also compatible with 802.11a, 802.11b, and 802.11g. If your Wii is unable to connect to the wireless network, I recommended changing the wireless security of your network.
Open Airport Utility, select your Airport Express and click Edit. Navigate to the Wireless tab and change your security from WPA2 Personal to WPA/WPA2 Personal. Then click Update on the bottom right. -

Installed new Airport Extreme 802.11n and now AOL will not accept
my outbound mail. I can get it to work about one time in 10. All settings have stayed the same with the only variable being the new router. Any thoughts?
iMac 24 duo Mac OS X (10.4.8) Airport Extreme 802.11nHello, and welcome to the Discussions.
Are you using the smtp provided by AOL? What port are you presenting it on -- Port 25 or Port 587? In Mail Preferences/Accounts/Account Infomation/Outgoing Server Settings, does the name of the (if the one from AOL) include your Username from your AOL email address (also referred to as account name, by AOL, I think)?

Itunes using Airport Express 802.11n and Remote app no longer staying connected
I'm running Windows 7. I find that my Remote app either keeps dropping Home Sharing (unless I toggle Home Sharing off/on in Itunes) or if it finds my library it cannot open it through the app. I can play music through my Airport, but it's the remote app that can't seem to connect with my iTunes. I should add that the remote app has the same breakdown on both my iphone 6 and ipad mini 2. So it's not the app, but some problem along the line (Airport express? router? Itunes?) Any suggestions?
OK, thanks for the info.
You'll need to jot down a setting that the AirPort Extreme (AEBS) is using in order to give the AirPort Express (AX).
Open AirPort Utility, select your AEBS and click Manual Setup
Click the Wireless tab below the row of icons
Jot down the setting that you see for Wireless Security
Close AirPort Utility
Hold in the reset button on the AirPort Express until you see the amber light begin to blink more quickly and then release.
Temporarily, position the AX near your AirPort Extreme and connect an ethernet cable from your computer to the AirPort Express
Open AirPort Utility, select the AX and click Manual Setup
Click the Base Station tab below the icons to name your device, establish a device password (write this down) and adjust time settings
Click the Wireless tab
Wireless Mode = Join a wireless network
Wireless Network Name = Exact same name as your AirPort Extreme wireless network
Enter a check mark next to Enable Ethernet clients
Wireless Security = Exact same setting as your AEBS that you wrote down
Wireless Password = Same password that your AEBS network is using
Confirm Password
Click Update at the lower right and the AX will restart. You can close AirPort Utility and disconnect the ethernet cable once you see the message that the settings have been saved to the AX.
After 30-45 seconds, you should have a green light on the AX. Now you can move the AX where it is needed and power it back up again. The ethernet port on the AX is enabled in this type of configuration, so you should be able to connect an ethernet device and connect. You may need to restart the device and/or the entire network to get everything synchronized. -
Airport Express (802.11n) and 360
Has anyone else experienced problems connecting an Xbox 360 to an Airport Express (new 802.11n model) wireless network?
For testing, I have a simple setup: my cable modem plugs directly into the Airport Express, and I have it set to create a B/G network, with no security enabled (temporarily).
A PS3, Wii, two MacBooks and two DSs can all connect to the Airport Express, but the 360 is unable to. While it can find the Express access point's name it cannot get an IP from it, and fails to connect during the attempt.
The 360 (and all other devices) work fine with an 802.11n Airport Extreme and an older Netgear router. Is there something specific I need to do to get the Airport Express to work with it, or is it just completely incompatible?
Both Airports are using the most recent firmware.
Thanks!I've been having the same issue. I used to have the old Express (b,g) and recently upgraded to n. My xbox seems it and "connects" to it but when I run the xbox live test, it just stops at network connection (I think that is what it reads) and says "not connected". I use my Express as a bridge. I also have Extreme but I wanted to keep Extreme to be 5GHz (n) and Express 2.4GHz (b,g) for iPhone use and old computers. For now, I have Extreme set as 2.4GHZ (n,b,g) but would like to go back to my old settings. This might be a firmware issue. Extreme had the same issue when it came out. Please share your thoughts or work arounds that you may have encountered. Thanks.

I need help with the speed of AirPort Express and ATT DSL.
I just discovered this, and it seems to have solved issues with my Time Capsule.
Open AirPort Utility; select your AirPort Express and choose manual setup.
Click >Wireless
Change Radio Mode to 802.11a/n - 802.11b/g
Click >Wireless Network Options
Change Transmit Power to 50%
Check >Use interference robustness < This step is purely optional. It's worth a shot.
I've been noticing issues with performance of my Time Capsule for a while.
It really started with lack of good range, followed by lousy performance with my iPhone 4 and iPad 2. I was lucky to get 10% of what my speed really is (1.5 Mbps vs. 15.9 Mbps). My iMac was the only thing that seemed unaffected.
I attempted to setup a Sony Media Player (stay away from them- junk!) then a Roku XD in my bedroom only 20' down the hall from the Time Capsule (direct line of sight). Signal kept dropping and performance was lousy for both. I want another new Apple TV for the bedroom, but that TV doesn't have an HDMI port. I ended up running an ethernet cable down the hall... until this morning.
After some digging, I found a forum talking about WiFi performance for iPhones and stumbled upon something kinda basically unrelated, but gave me the idea to dig into AirPort Utility a bit deeper. Changing power to 50% didn't sound logical, but lowering output power was mentioned in the forum. AirPort Utility goes from 100% to 50% then lower. Nothing between 50% and 100%. I'll know more about range later today, but I have a feeling it may be mysteriously improved as well.
Hope it works out for you! -

Enabling/ disabling wide channels doesnt change the avarage transfer rate significantly.
These are just a few examples of all tests I have done, I have tried every possible configuration and took screen shots of almost 80% of the test (if someone is interested in reviewing this).
I couldnt find a single configuration in infrastructure mode that is as fast as the ad-hoc connection, so I assume either apple's setup for ad hoc and using channels is different to infrastructure or the airport express simply is unable to perform the same way as the wifi cards being used inside my Macs (which is my conclusion unless someone proves me wrong).
-------------------------------------------------------------------- Keep in mind, my findings show a 100% faster network in Ad hoc mode on a 2.4 Ghz connection
This is quite unsatisfying as I have bought the airport express on Feb 9th 2010 and it was the latest available model according to local genius bar.
So to quote apple: "The AirPort Express Base Station is based on an IEEE 802.11n draft specification and is compatible with IEEE 802.11a, IEEE 802.11b, and IEEE 802.11g." yes it might be compatible but doesnt allow you to fully operate at those specifications or has anyone been able to achieve this somehow?why didnt I find this any earlier ...

Airport Express 802.11n and 802.11g clients?
Hi,
I hope this is the right place to ask this question.
Setup:
1. At this time I have a main AE 802.11g base for wireless surfing.
2. I have a second AE 802.11g connected to the hi-fi system. This second AE station is connceted as a client into the wireless network of the main AE base.
Question: could I keep this setup after replacing 1. with an AE 802.11n base (and keep the AE 802.11g client for streaming)?
Thanks you,
AndreI would still have one more question.
Are theses assumptions correct?
1. If the AE 802.11g client is switched off, the network will work at full speed (802.11n)
2. Turning on the AE 802.11g client would slow down the network at 802.11g level
3. switching the AE 802.11g client off again would lead to a recovery to full speed 802.11n
I am asking this because I do the music streaming only occasionally, must of the time I am using my MBP for work,
Thank you,
Andre -
i was trying to set up a brand new airport express and it keeps telling me that it cannot authenticate the base station.
so what do i do ?Hello curtcain,
Congratulations on your new AirPort Express! It sounds like you are trying to extend your wireless network with your new AirPort Express, but you continue to get the error that your base station cannot be authenticated.
I recommend following the steps in the article below for the issue you described:

Airport Express 802.11n problem
I have an Airport Express 802.11n.
I use it to send iTunes from my mac on my stereo system in the adjacent room, via my wireless network. I don't use it all that often. It has worked fine over the two or so years I've had it
A couple of weeks ago I had a new BT Home Hub 5 installed, this may be just a coincidence but I tried to use my Airport Express 802.11n yesterday with no luck. All I get is an amber flashing light. I've plugged the Airport Express 802 into the mains right next to my imac but that has not helped. My Airport Utility doesn't find or show my Airport Express.
What do I do? Can anyone help?
Hopefully
RobHere's an update:-
By re-setting my Airport Express 802 and updating the firmware, I can now get it to work when connected with an ethernet cable and changing my settings from DHCP to Bridge.
However, I still can't get it to work wirelessly.
Is this a known problem with the BT Home Hub 5 and BT Infinity? -
Does airport extreme 802.11a/c work with airport express 802.11n
does airport extreme 802.11a/c work with airport express 802.11n
"You can use the AirPort Express to extend the signal provided by the new AirPort, but the Express will not extend "ac" wireless since it does not have that capability. The Express will extend an "n" wireless signal if that helps."
This is what I am trying to understand.
So AXTRM w/ sep SSID for 2.4 (b/g/n) - call it SSID1 - and 5GHz (ac) call it SSID2 - WiFi Explorer confirms AC mode on 5G.
Using an AXPRESS to extend - I have the option of SSID1 b/g/n *and* the 5GHz ac SSID2 in the pulldown (it sees both?) --> if I select SSID1, it also extends this same SSID in 5GHz (both showing b/g/n) >> so I now have 3 signals on SSID1 (XTRM 2.4G, XPRS 2.4G and XPRS 5G) b/g/n and one signal on SSID2 (XTRM 5G AC) ac
If I select the 5Ghz ac SSID2 to extend - it prompts me "do you also want to extend (the 2.4GHz SSID1)?" --> select yes and I now have 2 signals for SSID (XTRM 2.4G & XPRS 2.4G) b/g/n and 2 signals on SSID2 (XTRM 5G 802.11ac & XPRS 5G 802.11 a//n)
Is the 5G SSID2 actually being extended from the Airport Extreme to the Express?
The reason I bring this up is I am having a lot of issues since iOS8 came out (especially on iPhone 6). Everything I am reading is pointing to when people have 2 AP's set to use the same SSID. When you walk to a part of the house where 5G 802.11 ac signal marginalizes, the phone does not immediately hand over to the 5G 802.11 a/n Airport Express.
My thought was separate the SSID's but to me, if the Express can't extend 5Ghz from the Extreme, it's taking a step backwards. I am better off getting a more powerful router like an ASUS and going with one AP, drop the WiFi roaming altogether
Any thoughts? -
Speed issue with TC and Airport Express 802.11n in WDS mode...
Here is my problem.
I replaced my older base station / Express duo with
a new Time Capsule (1TB) and a new Airport Express (802.11n).
I set up the network with the TC as base station running a WDS network (WDS main) and the Express is the WDS remote.
When I check the wireless clients from the TC, I find my iMac running at 130Mbits and the Extreme at 54Mbits.
No other wireless clients are connected to the network (I kept my slower network as a parallel one for my "older" Macs).
The only other connected device is my Dish network DVR that is connected via an Ethernet cable directly to the Express.
So my question is why does the Express not communicate at >54 speed rate with the TC?
And, why does my iMac connect with 130 and not with 300Mbits?
Any thoughts?Instead of using WDS, you should take advantage of the "Allow this network to be extended" option that is available for the 802.11n AirPorts including the TC. WDS only operates in the 802.11g radio mode.
Here's the basic setup:
o If practical, place the base stations in near proximity to each other during the setup phase. Once done, move them to their desired locations.
o Open AirPort Utility and select the base station that will connect to the Internet.
o Choose Manual Setup from the Base Station menu, or double-click the base station to open the configuration in a separate window. Enter the base station password if necessary.
o Click AirPort in the toolbar, and then click Wireless.
o Choose “Create a wireless network” from the Wireless Mode pop-up menu, and then select the “Allow this network to be extended” checkbox.
o Next, select the base station that will extend this network, and choose Manual Setup from the Base Station menu, or double-click the base station to open its configuration in a separate window. Enter the base station password if necessary.
o Choose “Extend a wireless network” from the Wireless Mode pop-up menu, and then choose the network you want to extend from the Network Name pop-up menu.
o Enter the base station network and base station password is necessary.
o Click Update to update the base station with new network settings.
