Airport Express 802.11n and high speeds impossible

Hi there,
well I have been playing around for the last 24-48hrs with an AirportExpress 802.11n wiht the latest firmware on it, to achieve high speed wifi ~300mbps as 802.11n allows. The following hardware was used during this tests:
Airport Express Model: A1264 Firmware: 7.4.2
1) Macbook Pro AirPort Extreme (0x14E4, 0x88)|Broadcom BCM43xx 1.0 (5.10.91.26)
and an
2) 24" iMac - AirPort Extreme (0x14E4, 0x8E)|Broadcom BCM43xx 1.0 (5.10.91.26)
Goal: Achieve to establish a high speed wireless-n infrastructure network.

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 ...

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???

I have AirPort Express 802.11n and ATT DSL Pro. The speed at the ATT modem is 4 Mbps however the speed at my computer, ipad, and ipod touch is only 1.7 Mbps. The ATT tech came out and said the slowdown is being caused by the AirPort router. Help!

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!

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.

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,
Andre

I 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

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 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 Warreir

More 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.

Airport Express 802.11n not seen in utility scan

I have an Airport Express 802.11n and the Airport utility scan isn't seeing it. I've reset it back to factory and still not being seen. Help please

After a factory default reset, the AirPort Express is broadcasting a wireless network with a name like Apple Network xxxxxx.
If you are tying to configure the Express using wireless, you need to make sure that your Mac is logged on to this network first, before you open AirPort Utility.
It's also possible to connect an Ethernet cable from your Mac to the AirPort Express and then open AirPort Utility. Once the Express has been configured an updated, you can remove the Ethernet cable.

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.

Speed issue with WDS, Airport Extreme, and Airport Express 802.11n

I have a Airport network set up using WDS and two airport base stations: an Airport Extreme 802.11n, and an Airport Express 802.11n. The Extreme is configured to be WDS main and is connected to my cable modem and other computers, while the express is WDS relay and acts as a switch.
I don't actually have any wireless clients connecting to the express. I'm using it to connect a mac with no airport card to the network by plugging it into the ethernet port on the express. For the most part, it works, and the mac gets a network address and can access the network. However, the connection speed from the Express to the Extreme seems slower than it should be.
Since both are 802.11n, and the Mac is plugged into the Express's 10/100 ethernet port, I figure the theoretical top speed that the Mac should be able to communicate with another device plugged into the Extreme is at around the same speeds as 100 mbps ethernet, since the 100 mbps ethernet connection should be the bottleneck in this case. In reality, the speeds are much slower: when I transfer files between a machine connected to the extreme (via ethernet) and my mac, the speed tops out at about 2 megabytes a second, if that.
I looked in the Airport Extreme's logs, and it indicates that the Express is only connected at 54 mbps, as though it were a 802.11g Express. I have no idea why this is! Also, the only wireless communication is between the Extreme and the Express, so one wireless device acting as a relay for another (and thus cutting the throughput in half) shouldn't be an issue.
Does anyone know why the speeds are so slow, and if there's anything I can do to improve them?

Hello Brian Kendall. Welcome to the Apple Discussions!
I looked in the Airport Extreme's logs, and it indicates that the Express is only connected at 54 mbps, as though it were a 802.11g Express. I have no idea why this is!
That is because you established a WDS which only runs in 802.11g. Since you have two 802.11n base station, you would want to take advantage of the "Extend a network" feature available with these base stations.
Here's a typical 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.

WRT160NL and AirPort Express 802.11n Connection

I have a Linksys WRT160NL that is currently connected to 2 Apple AirPort Express 802.11n via WiFi.
The connections are Cable Model via ethernet to WRT160NL
WRT160NL ethernet to PCs running XP and Vista
WRT160NL WiFi to laptops at 802.11g
WRT160NL ethernet to DirecTV HD Box
WRT160NL WiFi to Airport Express to ethernet connection of DirecTV HD Boxes (2 connections) (802.11g)
This current setup works. The hard wired components work as expected and the wifi to the AirPort Expresses work as well. The only issue I have is that the AirPort Expresses are only connecting to the the WRT160NL via WiFi at 802.11g speeds. I want to be able to conenct the AirPort Expresses at 802.11n speeds as I am having some streamin issues for High Def video. I verfied in the DHCP Client Table of the router that the AirPort Exresses are connected via "Wireless-G" to the routers. The AirPort Expresses are running the lastest firmware from Apple and I am running Firmware Version: 1.00.01 B17 on the router.
Any help/ideas on how I can connect the Apple Airport Express to the WRT160NL at 802.11n speeds? Are these 2 devices just not compatible with each other?

Thanks for the reply Scrooge. I have verified that the Apple Airport Express is 802.11n complaint:
http://store.apple.com/us/product/MB321LL/A/AirPort-Express-AirTunes?fnode=MTY1NDA0Mg&mco=MTA4NTc4MTE
I have also checked to make sure tha the router is set to Mixed mode:
Mode:     Mixed
Network Name (SSID):     xxxxxxxxx
Channel Width:    Standard - 20MHz Channel
Wide Channel:    N/A
Standard Channel:    2
Security:    WPA2 Personal
SSID Broadcast:    Enabled
The airport expresses are still connected at 802.11g according to the DHCP Client Table from the router. Is there any way to force the Airport Expresses to connect at 802.11n?
TIA

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.

I'm trying to extend the range of an Airport Extreme 802.11g by adding an Airport Express 802.11n. I set the Express up to join the existing network, but it does not make any difference in the range of the network. What's wrong?

Let me see if I can help you with the basic WDS configuration steps:
Note: To help facilitate the setup, temporarily connect the AXn directly to the AEBS LAN port using an Ethernet cable. Once the setup is complete, you can move the AXn to the desired location. For all configuration steps you will be using the AirPort Utility. Before starting, be sure to jot down the AppleIDs for both base stations.

Airport Express (802.11n) as non-NAT router?

I am considering to replace an old WLAN router by an Airport Extreme. For this, the Airport Extreme unit would need to work as a non-NAT router (my network consists of multiple independent subnets). I've looked through the (very helpful) discussions, but could not find a definitive answer to this question. So, can you tell me point-blank whether an Airport Express (802.11n) base station can be used as a *non-NAT router* (connected to subnet A via the WAN port, creating a different subnet B on the LAN ports)?
