Airport Express Very High Trasmit

Hi,
I noticed in the last 2 months or so that my Airport Express has started sending out extremely large amounts of... Something. I have no idea what.
I noticed some time ago that the green light on the front would start blinking like mad and stay that way for long periods of time (I have it set to blink on activity). I also poll my AX via SNMP using an open source tool called MRTG. MRTG reports in saying that the AX is transmitting at about 12Mbps out both the wired and the wireless interfaces at the same time. This isn't a case of traffic passing though my AX, it's originating from it.
There doesn't seem to be any rhyme or reason to when this happens. Today it stared just after 10am and and continues now. Some days it doesn't happen at all.
I've tried running a sniffer trace on my wired LAN but it doesn't pick anything up coming from the AX. MRTG also agrees with this since I don't see this high volumes of traffic reaching anything else on my wired network.
I'm running the logging in debug on the AX and it's not showing anything of use.
Does anyone have any idea what this little thing is doing?
Thanks!

As you may already know, when the AirPort Express Base Station (AX) is configured to "join a wireless network," it is performing as a wireless client ... just like any other wireless client (laptop, desktop, printer, etc.) on the network. It is most "chatty" when configured to share a USB printer attached to it or when streaming iTunes ... otherwise it's pretty much "quiet" with only enough communication between it and the network it has joined.
Wireless clients, accessing the Internet, should have no need to communicate with the AX during those communications nor should the AX need to pass Internet data coming in from your D-Link router back to them ... again, that is because the AX is NOT performing as a router.
Firewall settings on either the wireless clients or the D-Link would only have an impact during either streaming iTunes or printing to a shared printer.
There are a number of utilities available that can monitor network traffic and could possible provide you with a clue to what is going on. One I use that actually monitors traffic to/from the computer itself is Net Monitor Sidekick. It provides a real-time display of all traffic and can be filtered for the type of traffic (direct, gateway, broadcast, etc.) you are interested in.

Airport Express -- how high off the ground?

I'm thinking of getting Airport Express. I'd put it by my TV in the living room since that's where the stereo system is so I can pipe iTunes into the main system.
Only thing I'm now hung up on is where to plug the thing in. The closest available outlet is rather low to the ground.
So I'm wondering, for those who have Airport Express, how high off the ground do you think the outlet needs to be in order to allow all the cords to hang underneath and whatnot...?
The outlet is actually oriented sideways... do you think the unit would be able to stay in place if it's hanging that way? If not, I can easily use an outlet rotator, but this then brings me to the issue of clearance off the floor...
Thanks for your help.

Welcome to the discussions!
In general, wireless devices like the AirPort Express need to be placed in a higher location to avoid as many obstructions as possible. There's nothing wrong with attaching an extension cord to the device to move it up higher if that is possible.
If you must plug the device into a low wall socket, try to allow the Express as much of a free look into the room as possible.

Airport Express Very, Very, Slow

I have an iMac with a Airport Extreme router and an Airport Express being used as a wireless network extender.
The Extreme is connected to my Virgin broadband @ 29-30 meg and works fine. However on my next floor up where the Express is , not some 20 feet away it will not work above 2.5 meg and sometimes drops to below a meg.
I have been on many web sites to try and find why the Airport Express is so much slower but so far no luck and what I have noticed looking on the web is that I'm not the only one to have this problem and some of these complaints go back a couple of years and yet still no comment or solution from Apple.
I would be very grateful for any help .
Regards Jeff...

There are so many environmental variables that affect wireless networks that finding a solution to your problem can be elusive.
"Extending" a wireless network using an Express in the manner you describe essentially retransmits the same wireless signal it receives from the Extreme. If the Express is only capable of receiving a weak wireless signal, its signal may be strong but its throughput will be slow. The wireless signal it "extends" will be useful over the additional range provided by the Express but it will still be slow. To diagnose or confirm this possibility, unplug the Express and position a Mac in the exact same location. Whatever speed the Mac is capable of achieving will be similar for the Express.
Make sure the Macs you are using are connected to the Express vs. the Extreme. A Mac will not necessarily connect to the nearest access point, but if you position the Mac near the Express, turn off AirPort under its Wi-Fi icon, then turn it back on, it should connect to the Express.
If that test suggests the Express should be peforming better than it is, then investigate the wireless spectrum you are using. All new AirPort Base Stations are capable of creating and "extending" both 2.4 and 5 GHz networks. Generally speaking, 5 GHz is better due to its far greater number of available channels and less competition from neighboring wireless networks. Make sure the Express is configured to connect and "extend" the 5 GHz network and make sure the devices using it are also using 5 GHz.
If you are using 5 GHz, and the Express is in an area that receives a good wireless signal from the Extreme, and you are still observing poor performance, then there may be an internal parameter that has become corrupted in the Express. In that event a "hard reset" and subsequent reconfiguration is justified, followed by a repeat of the above tests.
If that fails to achieve any improvement, the possibility of a defective Express should be considered.
In the end a "roaming network" is a far more effective installation. It requires connecting the two with an Ethernet cable and a degree of labour that you may or may not wish to undertake yourself.

Airport express very slow when extending Time Capsule

I'm trying to help my father solve a networking problem.
For the past several years, I had him using an airport base station and (2) Airport Express units as extenders.
He was using a circa 2004 Powerbook G4 17" and a MacPro Dual Core tower unit.
I finally got him to upgrade the Powerbook to a the new Macbook Pro i7. With the older computer out of the loop, I also upgraded him to Time Capsule.
Everything is installed and running now. However, the network speed in portions of the house where the Express is supplying the signal is very slow. A test on the laptop with DSL Reports gave an average upload speed of about 200.
When I move the laptop right next to the Time Capsule, I got a DSL Report speed of 22,000!
This issue is not laptop specific (it shows up more on the MacPro because it's in a back room), but seems directly related to the speed passing through the Airport Express.
What did I do wrong or do the Express units need to be upgraded (they are on firmware 6.3)?
Thanks!

Bob -
Was wondering if you can elaborate on your response and perhaps help me? I apologize if I have missed this topic covered elsewhere.
I am using a N-capable Time Capsule and an older model G-speed airport express. My biggest issue is that my wireless speeds are 1.5 download and 1.9 upload when in fact my cable modem pumps out 15! In reading your posts I see that my network is likely dropped down to G due to my old express, and in fact my computer may be running of a spliced version of that if using WDS settings?
I think i'll end up calling apple support at some point but was curious if you can go over the facts of using N and G together, and if i can have my macbook pro speak to my N network only and my iphone 3G speak to G airport express only?
Last piece of info is I use the airport express for my music.... not sure if this means they must be WDS or not? I'm just looking to get my N devices as fast as possible while continuing to use my G express. If you tell me i need to upgrade to a N express I can live with it.... but if i can avoid the $100 and work with what i have...all the better!
Thanks in advance,
Joe

After upgrade to 7, volume level to Airport Express very very low!

After installing iTunes 7, suddenly the level of volume when sending to Airport Express is very very low.
This is true on my Macbook and also on a friend's Macbook Pro.
Volume from computer speakers is the same as before.
Anybody got a fix?

ROCK ON!!
You appear to be right! However, instead of removing
Bonjour for Windows I just went into Control Panel \
Administrative Tools \ Services and stopped the
Bonjour Service. Then I restarted iTunes and my
AirPort Express devices were available again via the
[Remote Speakers] button.
I also updated my other computer to iTunes 7.1.0.59
(Bonjour for Windows was not installed on it) and it
is working with my AirPort Express devices too.
I'll update my other posts...
Thanks Toonz!!
I had the same problem too. Upgraded iTunes 7.1 on my PC and the Airtunes remote speakers disappeared. I guess there is a conflict with Bonjour using the same UDP Port. So as suggested I disabled Bonjour which caused the Airtunes to show up again and I re-enabled Bonjour.
Let's see if this holds up with a restart. Silly Apple - they should really fix that.

Airport extreme(n) and airport express (b/g) problems

hi,
i have for a few years an airport express (b/g). the airport express is connected to my cable modem.
i also have a newer airport extreme (n) which was still in the box but i want to use (as it must have a bigger range ?). in fact i want the extreme to reach my playstation 3. (the connection from ps3 to express sometimes drops as its signal is too weak)
if i also connect the airport extreme to the cable modem, it shows with apps like "airradar" (on my macs) or "wifitrak" (on my iphone) that the strenght of the airport express is higher than my airport extreme. even if i set the extreme to 5ghz. both express and extreme are placed near each other. am i doing anything wrong here ?
below devices need to be connected.
1 macbook g4 (b)
2 macbook pro (n)
2 mac pro (n)
1 wii (b)
2 nintendo ds (b)
1 ps3 ?
with other words i need some advise in how to set up both a airport extreme and express network on the same cable modem.
thank, michiel

question: i below what should i do ?
1) put a cable from my cablemodem to the airport extreme bs;
2) put a cable the airport extreme bs to the airport express bs.
Yes on both. Your network configuration would look something like the following:
Modem > (Ethernet) > \[WAN port] AEBSn \[LAN port] > (Ethernet) > AX
do i have to reset the modems and are there any setting i should be aware of ?
Yes, it's always a good idea to both reset both base stations and, after doing so and before configuring them, perform a complete power recycle of your network equipment.
So in this case ...
o Power-down the modem, AEBSn, AX, & computers. (Order is not critical.)
o Reset both the AEBSn & AX. (Again, order is not critical.)
o Power-down each base station after performing a successful reset.
o Power-up the modem; wait at least 15 minutes.
o Power-up the AEBSn; wait at least 10 minutes.
o Plug-in the AX; wait at least 5 minutes.
o Power-up your computer(s).
o Use the AirPort Utility to reconfigure both base stations as required.

Another issue with Mac+PC & Airport Express network

Okey here's my problem. Yesterday i got my very first Mac (iBook 12") and i'm very happy about the computer in general. I also have Airport Express wireless base station. My other computer is table-PC and it has Planet WL-8314 PCI wireless card in it. I have ADSL-modem that i used with ethernet connection.
Now i want to connect Airport Express to ADSL so that both computers could get wireless internet connection and PC could be able to connect to speakers with Airtunes.
iBook connects to Airport Express very easily. No question there. But my Windows XP (service pack 2) PC is driving me crazy. I have configured the network using the admin utility from iBook. I've tried fully open network, use mac-address, WEP and WPA, but nothing works. I've installed Airport Express applications to windows as well but it doesn't connect.
Here is my current settings (Hope i can translate them correctly to english, i'm using finnish).
Encryption: WPA2 Personal
Encryption type: WPA OR WPA2
Connection: Ethernet
DHCP is in use
Share IP-addresses "checked"
by sharing one IP-address (DHCP and NAT) (use 192.168.1.1. addressing)
As i said i've disabled encryption, used mac-addresses and even made it fully public but nothing helps.
When i configure Airport Express from iBook my PC shows the network and does recognize the name of the network correctly and even if there is an encryption in use or not. If i'm using WPA and trying to connect, my PC asks for password but when i give the correct password it just stays stuck - nothing happens. The same thing when i try to connect without any encryption and passwords. It just tries and tries and tries... and fails.
This feels pretty hopeless. And the weird part is that yesterday i got it work for maybe an hour or so. Then Windows crashed and when it loaded again the same settings did not work anymore. So there are really weird things happening. And that period when it was working the admin utility worked in PC as well.
So any ideas what i could do. I'd really apreciate any help that can guide me to make my network fully work. So far it works perfect only with iBook - well better than nothing .
iBook G4 Mac OS X (10.4.3)

The connection i managed to establish last night didn't last very long. When i restarted Win XP, the connection was lost again. Anyway now i think i have solved the problem. All i had to do was to not set Windows XP take control over wireless network configure. This was done through unchecking one option. Then i could open wireless network adapter's own configuration tool and establish a connection to Airport Express wireless network.
So basically i had to punch Windows XP's native tools down in order to get the connection work at all. It just amazes me why such feature exists if it doesn't work.. Anyway i'm happy now and hope this discussion with myself in this thread might help some other as well .

Airport Express 802.11n - speed, throughput, bandwidth problems only 1MB/s

Hi there,
I got a brand new Airport Express with 802.11n. But I'm really disappointed with the speed in a draft-n-only environment.
Before I used as a router my 54Mbit/s Linksys WRT54GL with DD-WRT v23, which gave me on its g-Standard network a throughput of 3 MB/s when copying something via finder to my Ubuntu server.
But with the new AE I got only 1 MB/s as transfer rate for the same job. I tried already various configuration setups, but nothing helped. It seems to me if there is a bandwidth limitation thing in the AE.
Can someone help me to find the reason for my problem or give me some advice after what I have to look at?
Many Thanks,
Jan.

Welcome to the discussions, Tiggar!
A few suggestions from here, where my AirPort Express far outperforms my older "g" router.
1) Try to position the AirPort Express as high as possible and away from any other electronic gear. The general design of the product unfortunately encourages users to position the device low on a wall, often behind a desk and close to other electronic devices that sometimes can interfere with the wireless signal. Use an extension cable to get the Express up high and give it as much free air as you can.
2) You need to remember that higher frequency "n" signals...although faster...do not penetrate walls and other obstructions as well as lower frequency "g" signals. Try to establish a line of sight situation between your computer and the Express if possible and mimimize obstructions in the signal path.
3) Your Linksys may have been using a different wireless channel than the Express. Try different channel settings on the Express to see if you can find a good channel that is free of interference. To do this, open AirPort Utility, click Manual Setup and click the Wireless tab below the row of icons to get to the Wireless settings page.
4) Turn off any cordless phones that you may have there for an hour or so to see if you notice any improvement in performance. If you do, try to position the cordless phone as far away as possible from the AirPort Express.
Let us know if things improve when you can.

Apple Airport Express - drops wifi connections after a day or two.....??

Dear Users,
Can anyone assist me, I have 2 Apple Airport Express recievers and an Apple TV2 connected to my iMac. The Apple TV is connected via ethernet and a gigabit switch via the BT Infinity Router. The 2 Apple Airport Expresses are connected via wiresles to the BT router.
Everything works fine, music streams perfectly most of the time.
But after 24-48 hours of being dorment the Router seems to drop the wireless connections to the Apple Airport Expresses, if you reboot the router they connect again immediatley. I have adjusted the router settings to 802.1n, instead of 802.1n/b/g, which seemed to work better for a few days and the connection never dropped and now the problem has started again.
Frankly its not the end of the world, but it means I have to reboot the router everytime we want to use all zones for music, which when you have a wife that moans that 'my setup is too complicted and has to be rebooted everytime', it would be great to resolve this for once and all.....
Have a I missed something simple or do I need a new router/Airport Extreme?
Thanks in advance
Matt

The whole idea here is to test by first powering off your "extending" AirPort.
Then, take a measurement with your laptop at the location of the "extending" AirPort.....to see what quality of signal that it is receiving. Remember, it can only "extend" the quality of signal that it receives.
You would want to see a minimum SNR of 25 at the location of your "extending" AirPort Express. Higher would be better. If it is less than 25, you need to move the "extending" Express closer to the "main" router so that it will receive a better quality signal to extend.
Once you have a location with a decent SNR of 25 or higher, then power the "extending" Express back up at that location.

Airport Express as very slow in "extend wireless network" mode

Hi!
I am using a Airport Extreme (fourth generation) as a wireless router and a Airport Express 802.11n in "extend wireless network" mode.
I've set the Airport Extreme mode to 802.11n only - and all devices connect to the Airport Extreme as 802.11n Clients properly.
But as soon as they connect to the Airport Express, they only work in 802.11b/g mode (although they are capable of n)
and the connection is very slow - around 1Mb/s:
http://imageshack.us/photo/my-images/804/bildschirmfoto20111211u.png/
Can i force the Airport Express station to accept only "n" connections to speed up my file tranfers?
Thanks for any help!

Where is the AirPort Express located in relation to the area that needs more wireless coverage?
Ideally, it would be at a point that is about half the distance between the AirPort Extreme and the area that needs more wireless coverage....and....there would be no obstructions like walls and/or ceilings in the signal path....tough to do in most homes, so do the best that you can.
Avoid placing the Express down low on the wall and use an extension cord to get it up as high as possible with a free look into the room.
The Express will normally "extend" what it receives, but you could try the following to see if it helps:
Temporarily, change the Wireless Mode setting on the AirPort Express to "Create a wireless network" and change the Radio Mode to "802.11n only".
(You may have to hold down the option key on your Mac while you click on the Radio Mode selection box to see the "802.11n only" choice). Then change the Wireless Mode back to "Extend a wireless network" and Update.

Very Slow 12" Powerbook with Airport Express - 15" PB OK

Here's my problem; Our 12" 1.5 PB is very slow with Airport Express but It is OK when directly connected to the cable Modem via Ethernet. We also have a 15" PB 1.67 that works great with Airport Express & Ethernet. The 12" PB takes approximately 4-10 times longer to load Internet pages than the 15" PB. Here's what I've tried so far without success;
- made sure software was up to date (10.4.8)
- turned off the A/E security
- different A/E channels
- moved the A/E base station to another location
- a differrent A/E base station
- a Linksys WRTG54 base
- new Airport Extreme Card in 12" PB
- ran Apple hardware test on 12" PB - checks OK
- re-installed fresh OS and Apps from original install disks
- Firefox instead of Safari
- new user account on 12" PB
- re-installed original 512 RAM
Any suggestions would be greatly appreciated!

Jerry,
You're not going crazy, by the way. I have the exact same problem with my 12' Powerbook. I even tried swapping airport cards with another Powerbook. No luck. Ethernet is ok.
Any help is appreciated.

Airport Express has very weak signal even to the next room

I am wondering why my airport express has a weak signal. The signal to the next room(about 4 or 5 meters away), is so weak that you can only see one or 2 lines from the graphic at the internet connect. My base station has the last firmware from apple. Has anybody else experiencing this problem or knows what could be wrong?
Mac mini G4 1.25, iMac G5 2.0, MacBook 2.0, iPod 20Gb, iPod nano 4Gb, iPod 30Gb Mac OS X (10.4.7)

I have tried changing channels, I have tried using interference robustness but nothing seems to work. Isn't it so wierd thought that in the same room within 1 meter distance, the signal becomes from strong to weak, to zero?? The funny part also is that when i change channel for a few seconds the signal is very strong until it drops to zero. When i try another wireless device doesn't seem to have this problem but only with airport express base.

Very slow printing from Konica connected via Airport Express

Hello folks,
I have a very strange problem with erratic printing to a network printer, connected to an Airport Express via ethernet.
The Network:
- Draytek modem/router hosting DHCP
- Time Capsule connected to Draytek. It's in bridge mode, and runs the WiFi network
- Airport Express 1 in "Join a Network" mode, ethernet clients allowed
- Konica Minolta Magicolor laserjet printer connected via ethernet to AX1
- Airport Express 2 in "Extend a Network" mode elsewhere in the office
All client devices on the network are getting IP addresses in the correct range etc. I have fixed the IP of most devices at the router level, so they don't change.
Client Macs print directly to the printer using IPP (or might be LPD, I can check if relevant) using apparently a correct driver and IP address.
WiFi network is very strong throughout, and the distance between Time Capsule and AX1 is just a few feet.
Here's the problem:
At the start of the day, the printer works just fine. Fast.
Then, inexplicably, you send a document to it and the print queue reports "Spooling....xx%" which increases painfully slowly compared to when it's working normally.
This happens randomly with both small and large files. A modest photo can take over an hour to fully spool and print when it's doing this.
Turning the printer off and on again tends to make it work properly, until the above happens again.
This is driving me mad. Is there a problem with:
(a) The WiFi network or airport hardware
(b) The printer
(c) The drivers
(d) The printing protocol
(e) Me
(f) All of the above
Any insight would be most welcome. The Konica tech reckons it's working, but I think he didn't spend long enough sending print jobs to it for the problem to manifest.
P.S.
One of my main questions is, when the print queue says "spooling", is this the process of progressively sending the file over the network? Or does spooling occur when the data is either already fully arrived at the printer, or hasn't left the Mac yet?
Could the printer's unwillingness to accept data cause the slow spooling? Why might this happen?

It should work. Enable Printer Sharing via System Preferences -> Sharing. The Mac does need to be turned on.
P.S. Try to just post one thread on your question instead of crossposting over several forums.

Very high latency on my MBP 3,1 (mid 2007) with airport extreme card 0x168C

Hi
I wanted to let you know that i filled a bug report concerning a problem involving a MacBookPro3,1 and my airport extreme card (AirPort Extreme (0x168C, 0x87) Firmware Version 1.4.16.2)

Obviously, my Mac has very high latency where my PC works as expected.
I tried resetting the PRAM, but i didn't affect my results.
I tried updating Airport with the latest AirPort Client Update (http://support.apple.com/downloads/AirPortClient_Update_for_MacBook_and_MacBookPro), but my hardware wasn't eligible for that update (Mid 2007 MacBookPro).
I believe this isn't a hardware bug because i get acceptable ping results when next to my router or in other rooms of my flat.
Can you help me with that bug ?

Ok, I must have jinxed myself.
High latency with my Negear WPN824v3. As previously mentioned, the other wireless computers connect fine. Latency remains regardless of the power connected or not.
Please advise.

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.
Comparing to: Ad Hoc Network Wireless-N iMac to Macbook Pro

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 ...
