Voltage specs and international question about Airport Extreme (802.11n)

I'm about to travel to Korea to teach English for a year so I'm preparing all my electronic gear for the journey and I've come to a curious question involving the Airport Extreme with 802.11n.
First of all, I'm worried about voltage (Korea runs on 220v / 60Hz). For most hard drives (and Apple hardware in general it seems) the power supply is auto-switching 100-240v 50/60 Hz, but when I looked at the official specs for the Airport Extreme (hereafter AEBS) this info is conspicuously absent. The AEBS itself runs on 12V DC power, which is listed in the specs, but the input tolerance for the AC adapter isn't mentioned. I checked the specs for the Time Capsule since the hardware is presumably very similar and it is explicitly 100-240v. Likewise the replacement power supply available from Apple is listed as 100-240v, but since it is a replacement part I'm not sure if it is the exact same make as the adapter that ships with the AEBS in North America. If someone knows the definitive specs, I would appreciate an answer.
Secondly, when I tried searching the Korean Apple site (www.apple.co.kr) for specs on the Korean version of the AEBS to see if it was the same, I discovered that the Airport Extreme isn't available in Korea (although the Airport Express and Time Capsule). Does anyone know why this is? Is it possible the Airport Extreme doesn't comply with Korean wireless standards (I know the iPhone isn't being released in Korea because of laws about middleware that must be installed on cellular phones in Korea)? It seems safe given the availability of the Time Capsule in Korea, but does anyone have any specific knowledge about the Airport Extreme or Wi-fi regulations in Korea?
Sorry if this is a strange question, but I'd appreciate insight from the more experienced/advanced Apple users out there.

Thanks for the response. I guess what I would like to know is if I am closer to the newer 802.11n AE base station with my laptop, will it ignore the older base station and communicate directly with the stronger signal, or does it communicate with the weaker, more distant signal. Does the laptop automatically determine which base station has a stronger signal and choose it, or is it fixed which base station the laptop communicates with?

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.

WMM for AirPort Extreme (802.11n) - UMA T-Mobile not working...

Is there any chance we'll see WMM (WiFi Multi-Media) in a firmware upgrade anytime soon? I noticed that according to the WiFi Alliance's website, when the AirPort Extreme was certified, it supported WMM!
http://certifications.wi-fi.org/wbcscertified_products.php?search=1&advanced=1&lang=en&filter_company_id=&filter_cat egory_id=&filter_subcategory=&filter_cid=&date_from=&date_to=&x=30&y=18&selectedcertifications%5B%5D=33
As an early adopter, I just got a BlackBerry 8320 from T-Mobile, which does UMA, so you can use the phone over WiFi. Works awesome with wireless routers that do WMM, basically doesn't work with my AirPort Extreme... As you might imagine, this is quite frustrating, as I have particular desire to have two APs, for basically no reason!

I shot this across... let's see if anything comes of it:

Subject: a rather pressing Airport Extreme (802.11n) issue
i'm not sure if the person receiving this email will have any power (or will
care enough) to do anything about sorting this problem out, but hey...
better to try and fail than not trying at all, right?
anyway... here goes:
i am a die-hard apple user- heck, even a long-time stockholder- and recently
bought an airport extreme (802.11n) router for my house. it worked
flawlessly and i thought it was the best thing since sliced bread... well,
until i picked up a UMA phone from T-Mobile.
UMA is a service that routes your calls over WiFi. for some reason the UMA
service worked everywhere except over my Airport Extreme base station. as a
surprise, it even worked over my neighbour's older Airport Extreme (802.11g)
connection.
i swapped base stations (ie, brought his base station to my house, connected
it to my network) and it worked. so, it is an issue that is clearly
isolated to the new 802.11n base stations.
thinking it was only me with this issue, i dug around the internet and found
this discussion:
http://discussions.apple.com/thread.jspa?threadID=1152014&tstart=15
(if you want more, just google the keywords 'airport extreme UMA')
obviously there's no resolution and people are getting quite peeved that a
state-of-the-art base station can't do something than an older base station
can clearly do. so, can someone please look into this?
thanks!

Few questions about Airport Extreme/Express

I have a few questions about Airport extreme/express:
1 Can you access hard drive trough express?
2 I have cable NOT wireless modem. What would be the best option (speed-wise) to connect to internet- connect modem to Extreme and access internet wirelessly from it? To connect modem to Extreme and imac?
3 How fast is read/ write from hard drive connected to Extreme?
4 How many hard drives can you connect to Extreme (or Express if that is possible)?
5 Can you remotely sync Ipod nano/ shuffle using Extreme?
I really hate wire clutter around my desk. What I intend to do is to connect hard drives and printer to Airport Extreme and access them remotely. That would leave empty desk:).
Thanks

1. You cannot connect a hard drive to the Airport Express USB port.
2. The speed of wireless networking is faster than the speed of most cable internet services. Therefore, you won't notice any difference in your internet connection speed between (a) a cabled connection directly between Mac and modem or (b) a wireless connection between Mac and base station and modem.
3. Apple has not published any specs on the speed of hard drive access for the Airport Extreme N Base Station. Several people have posted their own measurements (do a search in this discussion forum), and generally those results are not very good.
4. Apple has not placed a limit on the number of drives you can attach to the Airport Extreme N Base Station (with use of a hub). How many do you want to connect?
5. You cannot remotely sync an iPod using the Extreme Base Station.

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.

I'm not sure how to post a message. I hope this might interest someone. The situation; 3 floors,I am having trouble with an an Airport Extreme, 802.11n on the top floor and a Mac Pro 3.1 on the bottom floor. Not always but often it has trouble seeing the Airport and making a connection. I have an older Airport Express, would it help to install it? would it work best if it was installed in the same room? should it be installed half way in between? Get another Extreme? The Mac Book Pro on the middle floor can see 11 networks in the neighbourhood if that might be causing a problem or would if I installed the Express. Thank for your consideration.

Thanks for your time ... I appologize for the font and colour, I compossed the question in pages and failed to notice the font colour as grey ... there are a variety of computers of various ages so I think it is using a setting that allows both 5G and 2.4 ... the connection to the Airport is thru a cable modem and cable does run throuhout the house ... maybe those hard wires would be a place to look at ... do you think that putting the 'Express' on the second floor might help ... thanks again ...

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

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.

I have a pc running windows 7. I got an Airport Extreme 802.11n Wi-Fi and the printer is now plugged into the Airport. The wireless router works fine but the printer shows as offline in control panel and in word. The printer is a HP LaserJet CP1525nw.

+For now I have it set to Share Public IP address - Is this correct for my Network Setup with The Airport Extreme being the only router being used ?+
This would be the correct setting if the AirPort Extreme is connected to a simple modem (one ethernet port).
*Settings I have Enabled*
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.
Interference Robustness often does more harm than good and should not be used unless you know you are in a area with a lot of wireless networks and you feel that your network is experiencing interference issues from a nearby network.

AirPort Extreme 802.11n as a wireless router and local network switch?

Good afternoon,
I'm curious if its possible to have the APE in wireless network mode and connect systems via hard line as well?
I have an AirPort Extreme 802.11n set to "Create a Wireless Network" mode that is attached directly to a cable modem for internet connectevity. My issue is that while all wireless devices (several iPods, two iPhones and three laptop computers) connect to the APE without issue (and have internet access), when I try to plug in a Windows 7 desktop computer via one of the ethernet jacks, Windows is unable to connect and shows the network as "unidentified," spitting back a private IP address as opposed to a local LAN (this behavior repeats for an Ubuntu Linux box as well).
Not sure if the APE is misconfigured, this is a Windows 7 issue or if its improper use on my part (though this also precludes me from connecting a gigabit switch to the APE).
Thank you,
Nathan

Properly configured, the AirPort should provide both wired and wireless network client with Internet access.
At this point, I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
If the above steps do not solve the problem, start over with step 1 above, but then perform the next steps between steps 1 & 2. above.
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Continue with step 2 in the first set of steps.
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

I have an 2tb time capsule 802.11n Wi-Fi base station can I use this as an external hard drive and use a new airport extreme 802.11ac Wi-Fi for my wifi?

You can use the 2 TB Time Capsule as a network drive. That means that it must connect to one of the Ethernet LAN <--> ports on the new AirPort Extreme, or connect to the network using wireless.

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 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.
