AirPort Extreme (802.11n), AirPort Express, and Client Limit Q

I'm very interested in the new AirPort Extreme (APE) due to the ability to access a hard drive from it for network sharing. I think that is awesome. But I have a few questions.
I am currently running 2 AirPort Express (APX) base stations for my network and am getting great signal strength throughout the house. No real complaints there.
One has the modem plugged into in the basement, and the other is set up as WDS. Unfortunately, I am quickly approaching the 10 client connection limit for the APX, so I was looking for a way to expand it.
If I get an APE and use the APX base stations as WDS access points, will I still be limited to only 10 clients attached at a time? And, since I assume the computer attaches itself to whichever of the three AP base stations has the strongest signal, will I alway be able to access the hard drive attached to the APE if I do that? I understand I won't get the 802.11n speeds (fine, I don't care) , but I would love to keep the APX base stations in my network for stereos and signal boosting.
Thanks for your help.

Is there a way to use the APX without losing bandwidth?
Configure it to operate as a wireless client. See KB 302153, AirPort Express: How to join an existing wireless network in client mode.
Maybe a way to use it as an extension other than WDS mode?
No
And why does it cut the bandwidth in half?
802.11b/g is not duplex so data can only be transmitted one direction at a time since the same channel (and radio) is used to transmit/receive.
If traffic is flowing from deviceB to deviceA, that traffic will interrupt the flow of data in the other direction and get part of the full bandwidth.
Each WDS link cuts the effective bandwidth in half because the traffic has to be retransmitted again. Let's assume that deviceA and deviceB are connected via WDS. Let's say that deviceA is connected to the internet and clientC is wirelessly connect to deviceB. Let's say that clientC is sending a 54 Mb file to the internet.
- 1 second to send 54 Mb file from clientC to deviceB
- 1 second to send 54 Mb file from deviceB to deviceA
So looking at the bandwidth between clientC and the internet, we see that the transfer rate is:
(54 Mb)/(2 seconds) = 27 Mbps
The effect of WDS becomes even more troublesome when you realize that while the data is being transferred between clientC and deviceB, deviceA has to shut off its radio so that it doesn't cause interference with the transfer. This means that other clients of deviceA are waiting. So WDS has large implications for big networks.

This would be the correct setting if the AirPort Extreme is connected to a simple modem (one ethernet port).

5 GHz name indicates that you have elected to use the option to assign a separate name to the 5 GHz network. This will allow you to "tell" compatible computers to connect to that network, rather than the slower 2.4 GHz network
Use Wide Channels is recommended for 5 GHz operation.

Airport Extreme 802.11n with Nortel VPN client

Hello,
Has anyone had any experience using the Airport Extreme 802.11n) with a PC (sorry, I have both a PC and a Mac)running the Nortel VPN client?
The new router works perfectly with the Mac but I also need to use the VPN on the PC for certain functions in my work. On my previous router (Dlink DIR625), I had to set a dedicated virtual tunnel to port 9550 to solve this issue. I think this might still be true for the Airport Extreme but I don't see how to do it. Any help would be appreciated. Thanks.

I had the same problem and an apple apple care tech walked me through it yeterday.
Call them, they were great.

Airport Extreme (802.11n) - Airport Express (802.11n) - XBOX360 (LAGGY)

I purchased an Airport Express to bridge my Airport Extreme to my XBOX wirelessly. I used the "extend this network" option to extend my current wireless network. The XBOX is connected to the ethernet port on the express. It seems to connect to the internet fine for streaming movies or downloading files. When I try to play games the connection is extremely laggy. I can manage (barely) if I only play as a client. If I host a game everyone in the room complains that the game is unplayable. _The latency is HORRIBLE_. This is unfortunate considering I purchased this specifically to connect my XBOX instead of the Microsoft wireless adapter.
My question is -- Is there a setting I can change to make the connection faster (less laggy) or is a better option just to return the device and get the Microsoft adapter?

Hello Micah Woods. Welcome to the Apple Discussions!
My question is -- Is there a setting I can change to make the connection faster (less laggy) or is a better option just to return the device and get the Microsoft adapter?
Since you are connecting your Xbox 360 to the AX via Ethernet only, I suggest that you reconfigure your new 802.11n AX as a ProxySTA instead of using it to extend the wireless range of the AirPort Extreme Base Station (AEBS). As a ProxySTA the AX would perform like an Ethernet bridge.
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. The feature should work with any wireless network: a, b, g, or n; and 5GHz or 2.4GHz. (Note that the Express, which ships with firmware 7.3, must also be updated to firmware 7.3.1 for this feature to appear.)

Airport Extreme (802.11n) & Airport Express (802.11g) single net by wire?

I just bought an Extreme-n to replace my ailing wifi router and wanted to use it with my existing Express-g to make a single wifi network so that I can have my 802.11n devices connect to the Extreme-n and the 802.11b/g devices connect to the Express-g using a shared wifi network. The tricky part is that I want the Express-g to be connected to the Extreme-n via Ethernet, not by relay, to get the best performance. This doesn't seem to be a standard configuration with WDS as it expects the Express-g to be a relay over-the-air, not by Ethernet. Is this possible, or do I have to set up separate wifi networks to do this? For either option, do I need to set up both the Express-g and the Extreme-n to be DHCP servers, or can I just rely on the Extreme-n to serve to both wifi networks?

In Apple's documentation and in threads in this discussion area you will find references to "dual band" networks. That is what you want to set up.
Each base station will create a separate wireless network.
The AirPort Express (AX) will connect via Ethernet to one of the LAN ports on the AirPort Extreme base station (AEBS).
The AX will be configured to create a wireless network and to act as a bridge (not sharing a single IP address).
All clients of the AX and AEBS will get IP addresses from the AEBS.

Airport Extreme 802.11n with XP and Utorrent or Azareus

I am very happy with my new router. I not get a strong signal in the garden and can extend further with my Airport Express if I so wish although I am using it for Itunes.
My problem is how to open ports (port forwarding or port mapping). Can anyone tell me how to do this. I am getting very slow download speeds.
Failing this
How do you place a wired pc in DMZ?
Pleeeease help, I do not want to go back to my crappy Belkin again (but I did get lightening speeds with it, just a very bad range.

USB Printing AirPort Extreme 802.11n

I've upgraded to the new AirPort Extreme 802.11n base station and am having troubles printing to printers that worked fine with my previous AirPort Extreme 802.11g base station.
Both USB printers are detectable for set-up in the Print & Fax Preference tab and can be printed to when hooked directly to my computer. They are also detectable for set-up in the Print & Fax Preference tab when hooked via the base station.
So, all set-up and settings are fine. The issue I am having which never occurred before is that the file is sent to the queue but is immediately labeled as stopped and will not print no matter what I try.
I've configured, reconfigured, reset,you name it but with no luck.
does anyone have any answers out there. Please help...

I have had the same issue repeatedly after upgrading to Leopard. I can no longer use my printer (Brother HL-2070N the "network ready one") with my airport extreme router. It used to show up before I updated to 10.5.2, now I can't even get it to show up at all. I reset the base station, unplugged, and then re-plugged in the printer, nothing worked. Then I tried to just delete it from my list of printers and re-add it, but now my computer can't find it! I didn't change anything on my network at all, and I had literally printed something just 10 minutes before I applied the update. Very frustrating for a $180 router.

Installing Airport Extreme 802.11n card in eMac killed keyboard?

Hello,
I got an Airport Extreme 802.11n base station and card for my eMac (which I want to run in the next room from my new Mac Pro) from local Apple Store yesterday.
I read and followed the card installation instructions exactly. - This included installing the software from the CD.* - But as soon as I installed the card, my mouse and keyboard lost contact with the eMac. (Totally unresponsive to key commands or mouse movement.)
I shut down my eMac and my (new) Philips DSL modem: both of these have shown no symptoms up to the time of the card installation. I un-installed the card and waited 5-minutes. Modem and eMac came back normally and so did my keyboard and mouse.
Just prior to installation, I ran DiskWarrior and Repair Permissions. Also: I unplugged and "re-plugged" the USB keyboard and mouse before shutting down of eMac & modem - this made no difference.
* I did notice: The documentation for the base station says the eMac needs Airport Setup Assistant 5.2. The eMac has Airport Setup Assistant 4.2. Yet - when I ran the installation program, it recognized and reported as updated Airport Setup Assistant 4.2.
Anyone have a solution to my loss of keyboard and mouse with card installed? Please - the Mac Pro arrives tomorrow.

I'm answering my own question:
I got around to simply trying a second time to install the Airport Extreme card in this eMac. This time - I shut it down before starting installation of the card.
I suspected that shutting down would be a good idea - since it seems very likely that the System needs to load whatever drivers or extensions are needed to enable Airport. But the instruction either did not mention shutting down before installing the card or I missed mention of it in my haste to complete this and numerous other tasks before day's end.
Anyway - that seems to be what happened because bootup was normal and the mouse cursor and keyboard worked as soon as the desktop appeared.
Now - I proceed to setup the base station and test it on the eMac. If all goes as I hope - in 36 hours I'll have both this old eMac and the new Mac Pro living happily in their separate rooms.

Airport Extreme 802.11n + NetGear WGR614

Just got new AirPort Extreme 802.11n base station and have it set up fine with my iMac and Apple TV.
I had planned to continue to use my existing Netgear WGR614 as an 802.11g access point so that when I connect my iPhone I do not degrade the speed of the AirPort's 802.11n.
I have managed to do this in a rudimentary fashion but what I really want to do is get the Netgear and the AirPort onto the same subnet even though they are broadcasting different signals - does this make sense?
When I connect my iPhone to the g router it of course can't see anything connected to the AirPort via Bonjour so no iPhone Remote...
Can somebody direct me to some assistance with this issue?

Oh nevermind - a little more searching and I found this great article from NetGear:
http://kbserver.netgear.com/kbwebfiles/n101496.asp
Still a bit confusing but I followed it and it works.

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.

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 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.

Airport Express and Airport Extreme 802.11n

Hello,
I have a Airport Extreme 802.11n Base Station set up and a old Airport Extreme (the one before the 802.11n model) set up which extends the Base Station's signal.
Is the old Airport Express broadcasting the 802.11n put out by the Airport Extreme even though the Express is an older model?
Thanks!

No, the older AX (Airport Express) is not capable of communicating in 802.11n protocol. It would be 802.11g at best.

Connecting AirPort Express to AirPort Extreme 802.11n

The following steps helped me set up an AirPort Express base station connected to a set of wireless speakers with my new AirPort Extreme 802.11n base station. I’m posting this because the process was not entirely intuitive, at least not to me.
I’ll assume you have set up the AP Extreme base station to connect to the internet and run your home network and that you are connected to your wireless network.
Make sure you set-up the AP Extreme base station to broadcast in 802.11n + 802.11b/g modes, i.e. both at once. You will also have to check he setting that allows the newtork to be extended.
Reset the AP Express base station so that in runs on the factory defaults by pressing the reset button with a paper clip. Wait for it to completely restart.
Launch the AirPort Utility. You should see both your AP Extreme and AP Express base stations in the left hand column. Click on the AP Express base station you just reset. When it asks to switch wireless networks do so. Then hit continue.
On the next screen select “Connect to my current wireless network” option and hit continue.
On the following screen select the “Extend the range of my AirPort Extreme or AirPort Express network” and hit continue. Do NOT select the “Join my wireless network” option even though it says this is how you connect to wireless speakers. This is the part that was not obvious to me. When I tried this the AirPort Express base station flashed orange and wouldn’t connect despite waiting 30 minutes.
Chose the network you wish to extend from the drop down menu. My keychain supplied the password for the network.
Give your base station a name and hit continue.
Select the main base station in the list provided. This is the one connected to the internet and hit ok.
The Airport Utility software will configure the network to accept the AirPort Express base station.
Now all that’s left is to connect your wireless speakers to the AirPort Exppress base station. You can now play music through AirTunes while being connected to your fast 802.11n network.

I recently setup an Airport Express in conjuction with my Extreme Base Station. I'm not really understanding how this method enables 802.11n connection speeds (via Base Station) to the internet and also allow streaming music through the Express at 802.11b/g. It's my understanding that if you want to be able to access the internet AND stream music at the same time the Express needs to join the network. In order for the Express to join the network (able to recognize the Base Station)...the Base station needs to be changed from 802.11n only to 802.11n (802.11b/g compatable)....which essentially means your connecting to the internet at 802.11b/g. If your wanting to keep 802.11n only on the base station...you would have to create a seperate network via the Express to stream music. What this means is you CANNOT access the internet and stream music at the same time. You would have to manually change Airport in the taskbar to do one or the other.
Am I off base here? If I am missing something please let me know...because it would be great to be able to connect to the internet at 802.11n only with a multi-case rate set to 23Mbps vs. the 11Mbps (maximum) of the 802.11b/g compatable option.
I guess what is confusing me is that my setup is basically the same as what was described above..minus having the "Extended Network" being enabled. How does extending the network change things?
