Airport Gigabit 802.11n and throughput dropouts?

I have the gigabit ethernet Airport Extreme. It was running wonderfully for some time. Streaming HD movies over 802.11n. Fantastic. But not long ago around 10.4.9 I started having this problem with my MacBook Pro:
When watching a movie, or copying a file the MBP would disassociate from the ABEX. Any network activity would stop. Until rejoined. Lately I'm in 10.5.2 and the problem still exists. However, clicking on the AirPort menu item will cause it to "re-associate" and things can continue but usually data corruption will happen.
I have noticed two other things: This happens more when it is set to 802.11n 5 gHz. This is what I originally had. I have no 5 gHz devices around. If I put it on 2.4 gHz it doesn't choke.
The data amount can be anywhere between 500 KB and 1.8 GB before it stops. As you can guess it's really annoying.
WPA2 is enabled.
I am considering a total wipe and re-install from scratch but I think it won't fix the problem.
Have any of you had similar experiences?

I have the same problem. Every once in a while I lose connection. When this happens the signal strength icon at the top goes grey. I can reconnect by clicking on it. It scans, finds the AEX, then is reconnected.
My AEX is running on the 5 GHz band (in answer to one of the questions, I don't think that the 5 GHz band is faster than the 2.4 GHz band, but I could be wrong - I think its just a matter of getting to an uncluttered frequency). All my portable phones in the house are at 2.4 GHz, so before I got the AEX for the 5 GHz my connection would drop out every time the phone was being used. After going to the AEX at 5 GHz the issue went away. After the last upgrade, it seems like I kept having these random dropouts.

I have a Airport Extreme 802.11n and I can't find the disc to install it... how can I install without the disc?

I have a Airport Extreme - 802.11n and I'm trying to install it -- but I don't have the disc. Any help would be so appreciated.

You don't need the disk, you can download and install the application that you need.
If you are using Windows 7, the link for the software is just below. Otherwise, post back to let us know what operating system your computer is using.

I have a Airport Extreme 802.11n and my T.V. is a panisonic,I keep losing the connection. Anybody have any answers?

Plenty of suggestions.. only you can find out which one is correct.
What model AE? What firmware?
Since Panasonic TV is not apple it will use SMB windows type networking.. everything but Apple does.
Are the names in the AE all SMB compatible.. ie short.. max about 20 characters.. no spaces and pure alphanumeric.
Is the security set to WPA2 Personal with a pure alphanumeric password of 10-20 characters.. more is fine if you suffer paranoia but isn't needed.
Fix the wireless channels.. so it doesn't flip flop like a dying fish.
There are only 3 channels for 2.4ghz that do not overlap, 11, 6, 1 although someone suggested 8 works well if you have heaps of interference. If you live in flat/apartment building you have heaps of interference.
Lastly is it stable if the distance is 3M direct line of sight?
If not then get a high power wireless AP and use that instead.

Severe interference between Airport Extreme (802.11n) and my Cable Modem

This post is in reference to http://discussions.apple.com/thread.jspa?threadID=897496&tstart=30
The root cause of the problem reported in the above post was determined to be a case of severe electrical interference between the 802.11n device and a Motorola Cable modem supplied by Comcast. I can provide the modem model number for anyone wanting it.
I found that at least 12" spacing is required between the 802.11n and the modem to avoid any significant interference.
I also found that if these two devices are physically adjacent the data rate performance thru the modem can reduce to almost zero.
I speculate that the 802.11n is radiating so much radio energy that it causes electrical interference with the modem's function.
N.B. The Airport Snow does not exhibit this same electrical interference.

I would connect the xbox 360 to the Airport Extreme with an ethernet cable and from the Airport Extreme back to my router would be wirelessly.
If you intent to connect the 802.11n AirPort Extreme Base Station (AEBSn) wirelessly to the router, this router would have to be another AirPort or one of a very few non-AirPort products that will work in a Wireless Distribution System (WDS).
Would this cause any latency problems?
Most likely, but that will depend on the two routers used in the WDS. If both are AEBSns, then the throughput performance would be competitive with at least 10baseT or 100baseT Ethernet. If not, then using an Ethernet cable may be the better option.

Setting up Time Capsule with existing AirPort Extreme 802.11n and AirPort Express.

I already have and am using an AirPort Extreme 802.11n with an AirPort Express. I want to set up a Time Capsule 802.11n. Which is the best way to configure this?

... Which is the best way to configure this?
The answer depends on what you need the TC to accomplish. If all you need it to do is perform Time Machine backups, simply have it join your existing network in client mode. It would be if it were to connect to your existing router (presumably your Extreme), not through an "extended" wireless network (presumably your Express).
If you need the TC to "extend" your network so as to serve additional wireless clients, you can do that also. Configure it to "extend" the network created by your Extreme.
As you can see it's quite versatile.

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???

AirPort Extreme 802.11n and PowerBooks?

I am about 1.5 seconds away from buying one of the new AirPort Extreme 802.11n base stations to work with my AirPort Express but I have some questions / concerns.
1) Is my Powerbook capable of being enabled to access an "n based network" or is my money wasted on a router capable of speeds my computer can not access?
2) Should my computer be capable of accessing this network, is the Airport Express Base Station I have capable of acting on this network in "N speed" too? I know the base station can be configured to act essentially as a relay to boost signal strength...if set up to do so will it dumb the speed down to "G speed"?
3) If 1 and 2 are true and the express base station dumbs the speed of the N router down, can I configure the airport express base station to ONLY act as a wireless conection to my stereo and not as a wireless router, so as to allow my Powerbook to access the "N" speed network but still broadcast my music wirelessly to the stereo?
Many thanks...I wish they just made this information clearer on pages like this:
http://store.apple.com/1-800-MY-APPLE/WebObjects/EducationIndividualCanadaCustom .woa/9804006/wa/PSLID?mco=F7D93AEF&nplm=D4141ZM/A&wosid=gE4h0LIBbghZ2sXpLP21Wij0 uPJ

Hey for any one still lookin....
1. It all depends on what your CARD is capable of. Your POWERBOOK is more then capable of "N" speeds. Your only limited on the bandwidth of the Cardbus slot. You would have to have a third party card to access the new "N" speeds tho. I'm not sure if the last batch of (pre MacBooks) Powerbooks even made it to the "G" standard. I know Apple just came out with a driver for the latest Macs that have an upgradeable Card and or Basestation to get to "N". I really don't think your Express is upgradeable.
2. You need to look at what models you have to figure out what their capable of. You should be able to go to Apple's web site to find out. Usually the Router will Dumb it down to the SLOWEST speed. Unless you were streaming your music, and playing a game online, and transferring a large file you shouldn't have a problem anyway. As long as you are not using the slowest product it won't dumb down.
3. Haven't got that far yet. I've used up all my brain cells getting this far, so good luck on your mission. Try starting another string with specifics on what you want to do.

Airport Extreme 802.11n and PPTP

Hi,
I've posted this question earlier in the wrong forum. Sorry for the double post.
I'm thinking of buying an Airport Extreme basestation. A problem I have with my current setup (using Airport Express) is that I have to use an extra router between my DSL modem and the Airport to connect to my provider via PPTP. Looking at the specs for the Airport Extreme, it seems that the new base station supports PPTP. But I really want to be sure, can I use PPTP with the Airport Extreme directly, or do I need to add an extra router as I have now?
Many thanks,
Don

You probably should ask in the AirPort Extreme (802.11n) discussion area.

AirPort Extreme (802.11n) and Airport Express

I wonder...
I do relase reading other posts that connecting my Airport Express as a client, joining my 802.11n (and 54g compatible network) will slow the whole network down.
But I can't do without the airport express, and I don't want to slow down my WAN 100 MBit internet connection either.
Is there a way to split the networks WITHOUT having to switch to the Airport Express-network when I want to play to the Express in iTunes? Has anyone tried some working configs of how to combine these two in a good way?

Saw a recent post just now...I guess the only solution would be to connect the Express by wire to the Extreme!

WDS networking issue - Airport Extreme (802.11n) and remote Airport Express

*Background Info:*
Airport Extreme 802.11n (Fast Ethernet)
Version: 7.2.1
Wireless Mode: Participate in a WDS network (set as main)
Network Name: @Home
Wireless Security: WPA/WPA2 Personal
Channel: 1
Airport Express
Version: 6.3
Wireless Mode: Participate in a WDS network (set as remote)
Network Name: @Home
Wireless Security: WPA/WPA2 Personal
Channel: 1
Radio Mode: 802.11b/g compatible
Connect Using: AirPort (WDS)
Connection Sharing: Off (Bridge Mode)
Issue
Please help as I'm having issues with my WDS network. I've setup using both the wizard and manual and also hard reset on both units to setup again but cannot get them both to communicate to one another. Both units are showing green LED under their configuration. For my last attempt, I've tried adding the Airport ID (MAC) of the Airport Express to the Access Control and also DHCP Reservations on the Airport Extreme but still no luck.
The Airport Express (setup as remote) does not even show up in the Airport Extreme's Summary as Wireless Clients. In the WDS tab, the Airport Extreme is set up as WDS main, Allow wireless clients box checked and WDS Remotes has the Airport Express' AirPort ID in the list. On the Airport Express, WDS is set up as remote, with Allow wireless client box checked and the Airport ID of the Airport Express in the WDS Main.
I can connect clients to both units. Both units are configured using the same Network Name and have the same WPA/WPA2 security key. The Airport Extreme (main) however is connected to my broadband so any devices or clients connected to it are able to get outside. Connected devices or clients are assigned IP address via DHCP with IP 10.0.x.x. If wifi devices or clients connect to the Airport Express (remote) they are assigned a completely different IP addresses 169.254.x.x, they are not able to browse the internet or talk to other clients connected on the 10.0.1.x network. The Internet Connection configuration on the Airport Express (remote) is Connect Using Airport (WDS) and Using DHCP. I've even tried manually and entered the IP address 10.0.1.199 that I had assigned to the Airport Express from the Airport Extreme and Router Address as IP of Airport Extreme (10.0.1.1).
I think I've tried everything but I'm still having this problem. The remote Airport Express is not extending my existing Airport Extreme network. Any ideas???

Christopher,
This may or may not be helpful, or it may be something you've already tried or are aware of so I apologize if that's the case.
I have been researching ways to set up the Dual Band Network supported by the AEBS and came across your post. I've got an AEBS and (2) AirPort Express set-up currently (AEBS is main and the Express are participating in the WDS as remotes) and I'm trying to configure one of the Express to utilize a 802.11b/g compatible network while the AEBS runs a 5Ghz 802.11n Only network.
AAR, since the AirPort Express are 2.4Ghz 802.11b/g ONLY (no support for 802.11n), you have to be sure to set-up your AEBS first and select "802.11n (802.11b/g compatible)" in the Radio Mode drop-down on the AEBS before you attempt to connect an AirPort Express. The AEBS should be set-up as your "WDS main" and the Express should be set-up as a "WDS remote" for the network you established when you set-up the AEBS.
Bottom line here is the Express won't be seen by the AEBS unless the AEBS is 'looking' in the 802.11b/g 2.4Ghz frequency.
Hope this was helpful.

Airport Extreme 802.11n and XBox 360 Disonnects

I've been using the Airport Xtreme 802.11n for about a week now and have been frequently disconnected from Xbox live on my xbox 360. The NAT is open and I'm directly connected to the router via an ethernet cable. I've given the 360 a static IP address and have forwarded ports 88 and 3074. The disconnects have happened both while in the middle of a online game and while I'm just on the Dashboard. Does anyone have any suggestions or is anyone else experiencing this. Please Help! It's extremely frustrating!

I have been having this problem as well. It says the server timed out, then my AEBS starts flashing yellow. Sometimes it goes back to green on its own, then other times I have to open up the airport setup. Oddly mine happens the same time every night, give or take 5 minutes.
For more info on my setup: XBOX360 wired to the AEBS, connected to a Motorola modem. At&t DSL is my ISP.
Any help would be greatly appreciated.

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.

Airport Express 802.11n and high speeds *impossible*

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 Extreme 802.11n and AirPort Express 802.11g on same network. Speed?

I am migrating all our Macs to 802.11n. I will have a new Extreme 802.11n base station, and all Macs will be newer models with 802.11n. However, I have an older Airport Express 802.11g that we use for the shared printer.
I have read that the ENTIRE network will run at the speed of the slowest device. Is this true? I know that the printer can only communicate at g, but will I also see the macs having to slow down to g? If so, I will upgrade to a new Express.

I have read that the ENTIRE network will run at the speed of the slowest device
That's not exactly true, but it will certainly degrade the network. A new Express (N) is your best solution to maximize the speed of your network.
