NAS for 802.11n?

Ok,
The new airport is supposed to support USB drives, thus making them like a network-type drive (called NAS, I think). I use an external SATA drive to work with video (it's still slow) on my Macbook Pro and I also use it to store my iTunes library.
My question is this: will the new Airport be fast enough for me to do these things WITHOUT being plugged in directly?
Lawrence

Hi Lawrence Ingram_Ii;
You asked; "I wonder. . . if I attach the external drive to the new AEBS with firewire; can I still leave the eSATA line plugged in to the back of the external drive and just plug in directly when I've got video editing to do? Or would I need to dismount if rom the network, and disconnect the firewire prior to using the eSATA connection?"
Leaving a drive connected twice is dangerous. If anything attempts to write to the drive over both of the connection simultaneously the drive will be corrupted. So the safest technique is to always have one and only one connection on a drive at any time. Anything else is asking for trouble.

AC Adapter for 802.11n Base Station.

Hi all,
Does anyone know where I can get a replacement AC adapter for a 802.11n Base Station?

Yes and they don't sell it separately.

Native Aiport cardbus/PCMCIA card for 802.11n

My wife has a Powerbook. For airport we are using a Microsoft (gasp!) MN-720 cardbus card. This has the same Broadcom chipset in it as an Airport Extreme card and is recognized by the Apple Airport drivers as a native airport extreme card. It works great and no third party drivers were needed. I'm interested if anyone has found a cardbus card that uses the same chipset as Apple does for their 802.11n implementation. The object being of course to have the Apple drivers see it as a native extreme N card. I'm aware of the Quickertek nQuicky cardbus card, but that requires their drivers. I'm looking for something that the Apple drivers will recognize as their own. Thanks ... Perry

Hardware differences. Core duos don't have the ability to be upgraded to 802.11n via the software update.

WLC recommended version for 802.11n

Hello,
I have to set up a wireless network using 802.11n. I was wondering if the 4.2 version is the best one? Is there any document that tells wich version to use depending on the the configuration we need to set up, for example?
jr94

Hello,
Thanks for your replies. I know that I will only be able to manage 1252 with that version, and it is the model of my AP, so it is ok. But I was wondering if I should better use 4.2 or another train of releases. As 802.11n has been released on 9/11, I do not know if 4.2 is the best one.

Flash Air III, how do I set it for 802.11N mode?

To whom it may concern: My Flash Air III is a very fine device. However…. My wireless receiver is setup for Wireless Mode: 802.11g with a rate of 48Mbps. Is there a way to set the Flash Air III to transmit in Wireless Mode: 802.11n? I would like to have a faster data rate.

It's really easy because it's mostly already set up... The AF-On button on the back of the camera already starts and stops AF.
To set up true BBF technique, you turn off the AF function at the shutter button. I believe it's Custom Function IV, 1: Opertaion/Others.... where you make button assignments. Navigate to the shutter button icon and press "set" to enter the options for that... change to the center one "metering start" and press "set" again. Done.
Optionally you can swap the function of the AF-On and "*" (AE Lock) buttons, using the same button assignment tool.

IMAC G5 ethernet port for 802.11n

Does anyone know if you could get the 1GB ethernet port to work with a new 802.11n Airport Extreme unit ? 540MBS sounds pretty interesting.

You have posted a question about your G5 Mac in the G4 iMac forum, so it might be getting overlooked.
You can wire your iMac into the newe AEBS, but the Draft N networking that you are talking about is not available for your Mac. The only Macs that have support for the Draft N standard are the currently shipping Intel units. Even my first gen BlackBook will not support Draft N.
The ethernet ports on the new AEBS are not gigabit ports either, so while your iMac can connect it will be limited to the 100mbps of standard fast ethernet.
Unless Apple comes out with an adapter for us, we will be left out.

Manual Static LAN IP address for 802.11n Base Station when using PPPoE

We have a network of about 75 machines. We want to replace our main router with the new Airport Extreme 802.11n base station. WAN connection is PPPoE so we'd use the NAT function. All IP addresses of our machines on the LAN are statically assigned.
Problem is our machines are assigned to find the router at a specific address: 192.168.0.254. The default base station IP in that subnet is 192.168.0.1. Is there any way to change the IP of the base station to 192.168.0.254 from the default of 192.168.0.1? We can do it if we have it join our existing LAN in bridge mode, but we want it to provide the main NAT functions AND connect to our ISP's PPPoE server WITHOUT having to change all our LAN devices to find it at 192.168.0.1. Possible?

The HH will only show devices which use DHCP in the list of devices, unless you've set the device to use a static IP in the HH Home Network page. It's a bit of a silly idea and IMO the software on the router is terrible, but you do it like this...
- Set the printer to use DHCP to get an IP address.
- Log in to the HomeHub 5 and browse to the Home Network page (http://192.168.1.254/index.cgi?active_page=9130)
- Find the printer in the list of devices and click on it.
- Click on 'Yes' next to the "Always use this IP address" option.
- Set the IP address on the printer statically and update your devices to use the new IP address of the printer (if it changed from what it was before).
That will ensure that the DHCP server in the HH5 doesn't lease the same IP to another device. This will also allow you to see the printer in the list of devices.

Wi-Fi CERTIFIED for 802.11n draft 2.0

This is quoted from:
http://www.wi-fi.org/80211n-draft2.php
"Beginning in June 2007, the Wi-Fi Alliance will start testing and certifying 802.11n draft 2.0 products."
Let's see when Apple gets certified.

hi tom,
if you open airport utility and click on your airport extreme.... then click on the wireless options you ca change your frequency there.
I swith between n & b/g as I have an Ipod touch & that works only with the b/g network.
hope that helps ....

G550 Wireless whitelist, which FRU to get for 802.11n upgrade

I have a preconfigured T4300 G550 that came with a 2 antenna 11g WLAN adapter. I want to upgrade to 11n and am aware of the whitelist. But in looking at posts here an elsewhere not all Lenovo device IDs will work in all systems so it's not enough to just get a Lenovo branded card.
Is there a dBase somewhere with contents of whitelists for various models? IOW, where can I find out which FRU I need for this G550 upgrade? Would a 42T0865 (Intel 4965) be suitable (knowing I'll run just 1 Rx)?
TIA

Ok, after doing a bit more searching I found a clue in a completely different forum:
http://discussions.apple.com/thread.jspa?threadID=2136789&tstart=0
Apparently I must have a neighbor with a WiFi router set to a wrong country region (I'm in Brazil), and according to the (foolish, stupid, and all-around knobbish IMSNHO) 802.11d implementation that Apple has chosen to follow in Snow Leopard, it sets its internal card's country region to the region of the first router that broadcasts to it, rather than being smart (like they were in 10.5) and setting it to the country region of the actual router you are connecting to.
I'm using the script that was offered on that page to reboot my Airport interface until it connects using Wireless N. Until then, this is a big AppleFAIL in my book.

How do you know if your Mac is 2.4 GHz or 5 GHz 802.11n?

We have a 2007 iMac and an original MacBook Air, which were both bought in January of 2008. And a brand new 17-inch MacBook Pro. Our Time Capsule is the older non-dual band model which was bought with the iMac and MacBook Air, again in January of 2008.
If they are all 5GHz, I would think I would want to set the Time Capsule's Radio Mode for "802.11n only (5GHz)."
Assuming that they are all 5GHz, is this what I should do for maximum efficiency, or does it really matter?
(And yes, I know that our iPhones would not be able to use the 5GHz band. Not a problem)

That's true. Apparently the 5Ghz band can use 40 mhz bandwith, rather than 20 mhz, which when combined with the relatively few 5ghz devices, means it can be quite a bit faster. I routinely get about 8-10 MB/sec (that's 64-80 megabits/sec) with my 2007 Macbook Pro and my Airport Extreme base station (802:11n). The signal from the Airport Extreme is pretty strong across even from about 150 feet away, and through several walls, but the speed drops significantly (to around 2 MB/sec at best)
Unfortunately, I'm not sure how to confirm your Macs support 5 ghz, apart from simply trying to connect to a 5 Ghz only network. I would assume that since my late 2007 MacBook Pro supports it, your Macbook (and probably Macbook Air) will support it too. I can't say for the iMac.
You can look in the Airport section of System Profiler, then look for an entry like this:
Supported PHY Modes: 802.11 a/b/g/n
Note the 802:11 a - apparently the "a" refers to the 5 Ghz band, which is used by 802:11n. So, if it shows this, I figure it should work fine.

After 10.6.8 upgrade, MacBook PRO doesn't acquire IP address via 802.11n wireless connection

After upgrading a MacBook Pro to 10.6.8, the machine connects to an 802.11n wireless access point, but will not acquire an IP address using DHCP. An iMac running 10.6.7, and an iPad2 both successfully connect and acquire DHCP IP addresses to the same access point. The access point is an HP Procurve MSM422 access point, a commercial data center level access point.
The MacBook Pro did acquire a connection and IP address when running 10.6.7, so this seems to be a regression introduced with the upgrade to 10.6.8.
The MacBook Pro running 10.6.8 will acquire an 802.11g connection to the same access point without any problems. The access point has different SSIDs for 802.11n and 802.11g.
Changing the IP settings on the MacBook Pro from DHCP to a fixed IP address doesn't solve the problem.
Just wanted to document this situation for those following problems with migration to 10.6.8.
If anyone uncovers the reason and has a work around for this situation, please share. I'll keep looking, too. I plan to do a combo install of 10.6.8 later today to see if this remedies the situation.

Deleting and recreating the AirPort connection doesn't help this problem. Neither does turning the AirPort on/then off, going from DHCP to FIXED IP addresses, or repairing permissions. I even upgraded the firmware in the HP MSM422 access point from 5.4.29 to 5.5.1 and that didn't make any difference, either.
Using the combo installer to reinstall 10.6.8 did fix the problem.

Is the 802.11n download compatable with my Mac Book Pro?

I have a Mac Book Pro with a core duo processor. I was wondering if I could purchas the $2.00 download and make my computer 802.11n compatable. I dont know if I need to get anything new, say a different airport card, or if I can just download the "new" software.

You'd need a new Airport card or ExpressCard for 802.11n. But if you just want it for Internet, don't bother, only for local file transfer, e.g. Time Capsule.

Configure standalone 1250 AP to support 802.11n

Been searching this forum about 802.11n setup. So far, I learned (from this forum) that to support 802.11n, I must use WPA2/AES (or open auth), and I need to ensure WMM is enable.
Q-1. Besides the above two, are there any other requirement I need to address in my configuration?
Q-2. Do I have to enable both 2.4Mhz and 5Mhz radio for 802.11n performance?
Q-3. Is there WPA2/TKIP option? If so, would this option support 802.11n? Or, it has to be WPA2/AES?
Q-4. From the command line, how can I verify if I have WMM enable?
I have read the 1250 AP Configuration guide, but I don't see specific discussion/chapter about 802.11n. If there is any good reading I can do, please let me know.
Thanks.

I will try to answer your questions:)
Q-1. Besides the above two, are there any other requirement I need to address in my configuration?
You need to configure 40mhz channel width in the AP 802.11a radio
Q-2. Do I have to enable both 2.4Mhz and 5Mhz radio for 802.11n performance?
Only enable 'N' on the 5ghz side due to only having 3 non-overlapping channels on the 2.4ghz
Q-3. Is there WPA2/TKIP option? If so, would this option support 802.11n? Or, it has to be WPA2/AES?
AES is the supported encryption standard for 802.11N.... not TKIP. WPA2/AES or OPEN is your only option
Q-4. From the command line, how can I verify if I have WMM enable?

1252 802.11n Throughput, no more than ~140Mbps?

Hello, I have read most of these ports regarding the speed of the 802.11n on the 1252 AP, and can't seem to figure this one out. I have a WISM with a light weight 1252 being powered by a power injector running 7.0.98.0 code. I have everything enabled for 802.11n, and connet with Windows 7 at 300Mbps. After doing many FTP speed tests I can never seem to break the ~140Mbps mark, even after enabling 802.11a 40mhz channel bonding and all the appropriate MCS rates and WMM/WPA2/AES settings. This is a mixed RF environment with clients running a/b/g/n all over. Am I missing something or is really the limit of our environment. I tested 2 different laptops with N cards. My card is an Intel 4965 ABG with latest drivers.
Thanks!

+5 to George. The maximum ever observed in very specific conditions (specific packet size, no one else connected) is around 170/180 "real" Mbps. In a typical real life scenario, reaching 140/150 is good and expected.
For the theoretical explanation, it's the data frame that is sent at 300Mbps. You must also count that EVERY single wireless frame has to be acked by the receiving side, that there are still the beacons and management frames sent at low data rates (1Mbps often, and not 300) and as george said it's half duplex, all in all 802.11a/g offer less than half the speed (20 instead of 54) and with a few protocol improvements 11n offers about really half the speed (150 with 300Mbps data rate).
It's actually the same concept with wired world. Gigabit ethernet means data frames are sent at 1Gbps speed but you have to count the protocol overhead (waiting for tcp ack, etc ...). The difference is that there is very little overhead on wired and it's full duplex so you get very close to 1Gbps.
Hope this clarifies.

Korean version of Aiport 802.11n still 130Mbps?

I bought my MBP in Feb/08 in Korea.
Until recently they did not allow the segment of frequency
limiting speed of 802.11n to 130Mbps.
Now I am using my laptop in Australia. So Is there anyway
that I can check if my MBP's Airport is still speed limited?
And if it is is there anyway of removing this restriction?

Hello Filippo Morelli. Welcome to the Apple Discussions!
Have you considered running a "Dual-Mode" network?
The set up would be something like the following:
o 802.11n AirPort Extreme Base Station (AEBSn) connected directly, via Ethernet, to the DSL/cable modem, and configured for 802.11n only.
o 802.11g AirPort Extreme Base Station (AEBS) connected directly, via Ethernet, to one of the AEBSn's LAN port, and configured for 802.11b/g. Optionally, the AEBS could be configured as the main base station in the WDS with the AX.
o 802.11g AirPort Express Base Station (AX) connected wirelessly to the AEBS as either a remote base station in a WDS or as a wireless client for iTunes streaming and/or USB printer sharing.
In this configuration, you would have separate wireless networks, one for 802.11n clients, the other for all others. Since the AEBS would be configured as a bridge, all clients on both wireless networks could access the Internet thru the AEBSn, as well as, communicate with each other locally.
If, and when, Apple releases 802.11n updates for existing 802.11g products, you could substitute them in piecemeal.
