If your iMac has the Core 2 Duo processor and is not the 17-inch, 1.83GHz model, then yes, it should be upgradable with the "n" enabler.

Unable to Connect Using New AirPort Express 802.11n

My mom purchased an AirPort Express 802.11n wireless router (AX) and I, as the designated "technology guru", was tasked with setting it up. Unfortunately, I am having problems out of the box.
When I connect it to the wall, it is found by AirPort Utility, but when I try to set it up, it is unable to connect to the wireless network. ("An error occurred joining the selected wireless network." "An error occurred, close the configuration window and try again.") This is annoying because I have an older AX and it was true to the "it just works" Apple mantra. It is also annoying because the error message has a comma splice.
Feeling pretty proud of my "technology guru" title, I come here to see what I could be doing wrong. I try connecting the computer directly to the router via ethernet cable. With this, I am able to setup my wireless network. I am still not able to connect to it. Additionally, once the AX has been configured, the AirPort Utility can't find it.
I tried updating firmware to 7.5.2. I've tried downgrading to 7.3.2. I've tried hard resets, soft resets. Every tip I could find I have tried. Please help. My self-confidence is wearing out.
Is it time for a call to Apple or a visit to the Apple Store?

Are you trying to configure the Express to "join" the wireless network?
If yes, the message you are receiving is likely an indication that you do not have the correct security settings selected for the Express. Unless the security settings between the wireless router and Express match up exactly, the Express will display the error that "an error occurred, etc".
The easiest way to confirm if you have this problem is temporarily set the main wireless router to "no security" and try to connect the Express that way. If you can connect, then you know that it is a security issue.
Please tell us the exact setting for security that the wireless router there is using and we'll try to give you some more ideas.
The Express will connect. It's just a matter of finding the right settings.

How do I connect my Airport Extreme 802.11n to Epson 645 Printer?

I can't figure out how to connect my Airport Extreme 802.11n to my Epson 645 Printer. Can anyone help me? Thanks!

You may want to try reinstalling Mavericks. Airport Utility installed by Mavericks may no longer connect to your older AEBS (though I've not heard that.) Installing the Old AirPort Utility (Version 5.6) on Mountain Lion | frank.is.
Reinstall Lion, Mountain Lion, or Mavericks
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and
     after the chime press and hold down the OPTION key until the boot manager screen appears.
     Select the Recovery HD and click on the downward pointing arrow button.
     Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu.
     Repair the Hard Drive and Permissions as follows.
After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
     Reinstall Lion/Mountain Lion, Mavericks: Select ReinstallLion/Mountain Lion, Mavericks from
     the Utilities menu, and click on the Continue button.
     Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is
                three times faster than wireless.

Broadcom 802.11n Network Adapter not working on Windows 7 64bit

As the title suggests, my laptop (Alienware m17x) is installed with the Broadcom 802.11n Network Adapter and Windows 7 64bit Home Premium. I have had several other driver incompatibility issues with Windows 7, but those I have slowly been able to resolve. This however just cropped up after two months of successful use. Yesterday it started failing to connect to the internet, telling me that no wireless connections are available. I live in a dorm, and everyone else on my floor has successful wireless, including my Ipod Touch, PS3 and XBox 360. I called Alienware/Dell Support and we spent hours trying to fix the problem and all look well until I rebooted my laptop this morning and the same issue reappeared. When I reboot my laptop, all I get is a notification that no networks appear in range. If I uninstall the broadcom chip and let windows install it after a boot up it works until the machine is rebooted a second time. I have tried over a dozen windows 7 drivers for the chip, and about half a dozen vista drivers and they all have the same results, works on the first boot, fails every time after that

Just registered to say, on an Alienware M17x system as well running Windows 7 Ultimate, here is a link to a solution that worked exactly for me:
http://forum.notebookreview.com/alienware/436486-guide-properly-solve-wireless-connection-problems-m17x.html
All I did was section I.a. If the link is down, I copied the only section that I needed to follow out of this guide, in order to get my wireless to work repeatedly without having to uninstall the wireless driver every single reboot. Now it works perfectly,
already connected to a wireless network on startup.
I.a. Disable Device sleep on disconnect
Some newer Nvidia Ethernet drivers have a feature called Device sleep on disconnect. This is the culprit. Normally, it should only put the Ethernet adapter to sleep when the cable is disconnected, but it's buggy and thus kills the wireless connection as
well.
Follow these steps to disable this feature on your Nvidia Ethernet Adapter:
1. Open the Windows Device Manager by hitting Win+Pause, then click on Device Manager on the left side.
2. Double-click on Network adapters.
3. Double-click on NVIDIA nForce Networking Controller (yes, that's the wired Ethernet adapter indeed).
4. Click on the Advanced tab.
5. Select Device sleep on disconnect.
6. Set the Value to Disabled.
7. Click OK and wireless should work again (might require a reboot afterwards, but probably not).

New Macbook Air will not connect to 802.11n, but my old 2011 model will

I have just bought a new MBA 13", i7, 8 GB RAM, 256 GB SSD.
When I connect to my home network I see it as a 802.11n network, but as soon as I log on, I only have 802.11g connection. I still have my old 2011 MBA, and it connects to the n-standard just fine.
I went to the local Apple reseller to have them look at it, but the problem was not present when connecting to their airport extremes.
Has anyone else had this kind of problem, and is there a known fix?

The warranty entitles you to complimentary phone support for the first 90 days of ownership. If you bought the product in the U.S. directly from Apple (not from a reseller), you also have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different.

Airport Drives Me CRAZY! New 802.11n Network Slower Than Old 802.11g/b

I've been using Macs since 1988 and consider myself an advanced user. However, every time I setup a new Airport wireless network or re-configure an existing one, I feel like a helpless newbie trying to figure out how to open a folder on my desktop. No matter how many times I read the manual or the help files or these forums, I can never grasp what seems like it should be a simple path from A to B to C.
Anyway, here's my current situation: I've been successfully (I think) running a 6 year old AP Extreme Base Station [AE] (in my home office addition) and 2 Airport Expresses [AX] (one AX roughly 15 feet from the base station--through sheetrock, and the second AX roughly 30 feet from the first AX--through sheetrock and some wooden stairs. (so roughly 45 feet from AE to 2nd AX). It wasn't the speediest thing going but it did the trick with older Macs.
I recently bought a MacBook Pro which supports 802.11n. I most often use this laptop at the point in the house furthest away from the AE (Base Station) The AE (Base Station) is in my home office connected to my MacPro desktop (see #1 below). In addition, the family iMac is also in that room furthest from the AE. Using the new MacBook Pro with the old 802.11/g/b network turned out to be painfully slow. I was experiencing the same slow network connection my family has complained about for years with their older Macs and 802.11g/b.
I decided it was time to upgrade the whole network, if only to speed up my MacBook Pro connection. Bought new 802.11n Airport Extreme (MC340LL/A) and 2 new 802.11n Airport Expresses (MB321LL/A). Setup did not go smoothly. Again, my normally competent Mac persona was reduced to a babbling three-year-old. Had three different Apple techs on the phone trying to help me through it. Got different, contradictory instructions from the last two. Finally got all three units working, only to find that not only does my MacBook Pro seem even more sluggish than when connected to the old 802.11g/b network, but my wife tells me web pages are taking at least twice as long to load as with the old network.
As concisely as I can lay this out:
*1. Airport Extreme (Base Station)*
Connected via Ethernet from its WAN port to my Comcast cable modem. One Ethernet (LAN) port on that AE is then connected via Ethernet to my Netgear 8-port Ethernet switch. Ethernet from switch to Ethernet port 1 on my MacPro. (MacPro does NOT have an Airport card because I forgot to order one. Also I confirmed that this setup was functional by connecting to the AE wirelessly with my MacBook Pro showing the name I'd given the new network prior to adding the two AX's to the mix).
Some Airport Extreme settings of note (all accessed via "Manual Setup" button):

SETUP/GOALS:
With Airport Extreme (Base Station) as the starting point, have the two Airport Express units with the strongest, fastest signal possible, provide Internet access (and file sharing, iTunes speakers capability) to three Macs (one older iMac, one older PowerBook and my new MacBookPro). Again, I believe my new MacBook Pro is the only one with 802.11n support, so I don't expect the other Macs to take advantage of the speed boost offered by the three new 802.11n devices.
+Any and all help with this will be greatly appreciated. Thanks!+

{quote}With the AirPort Extreme, in the AirPort panel, Wireless tab, click on the button for "Wireless Network Options", check the box for "5 GHz Network Name", and enter a different network name. (That can be trivially different, such as the name of the main network suffixed with an underscore and the digit 5.) Once configured that way, connect your "N" gear to each network in turn to see if one is any better than the other. (If you're wondering what effect this would have, it allows segregating your "N" gear from the older gear to prevent the older gear from slowing down your network. However, distance and interference from things like walls may negate any advantage.){quote}
William: I was gone most of yesterday, but had a chance to implement your recommendations today. I added the 5 GHz network as you suggested, but in order to connect to that at all with my 802.n11 MacBokk Pro, I need to be within a few feet of the AE (base station). If I try to access that network even from the next room (well within reach of both the AE and the livingroom AX, I get one bar and "failure to connect" messages just trying to logon to that network.
However, I did some experimenting that (as of right now, anyway) resulted in much faster network access, not only from my MacBook, but also from the older iMac which is the furthest Mac from the AE. According to my wife, that iMac is "loading web pages faster than I've ever seen them!"
Here's what I did:
1. Moved all three units to places where it seemed they would have the least amount of interference with the clearest path from unit to unit, also raising the height of both AXs from about 2-3 feet from the floor to about 5-6 feet from the floor.
2. Changed one setting on the AE (base station): Wireless Tab > Wireless Network Options > Multicast Rate ---> Changed this from Low to High.
I have a feeling the location shifts made the real difference, but I will try changing the multicast rate back to "Low" just to see what happens.

Does Mixing 802.11n with .11g Devices Slow the Whole Network?

Hi all,
I'm considering buying the new Airport Extreme as I also have a new Macbook Pro that supports 802.11n. I also have a couple Airport Expresses on my network, and my question is this:
Will the presence of the Airport Express units (which are 802.11g) drag the whole network into .11g speeds? I ask this because of this note on the Airport Extreme page:
Speed and range will be less if an 802.11a/b/g product joins the network.
Thanks for any guidance.

I did this the same way....
I connected my cable modem directly to the WAN port of my new 802.11n AirPort Extreme Base Station. I have selected 'n' only (5GHz). I call this network Saturn.
There are 3 ethernet ports on this new base station. Wired to one of these ports is my 802.11g Snow Airport Extreme Base Station. This base station will handle any 'g' services (like my friends who are using MacBooks/iBooks/PCs). I have 2 AirPort Express base stations that I use to play music on remote speakers, and wireless printing. It also has 2 Linksys wireless USB 'b' devices that connect to it, which 2 of my TiVos use to get their daily updates. I wanted to keep all of this stuff off the 'n' network since I heard it would slow it down. I call this 'g' network Zodiak. I can see both networks in my AirPort menu, and can select either.
In addition, I have an xBox that I connected directly to one of the wired ethernet ports on the 'n' base station, and I have a Linksys switch that is wired to the 'g' base station.
My only complaint is that I can't get to all of this stuff that is on the 'g' network. Which means, if I want to print something, I need to change my network, if I want to play iTunes out of my stereo speakers, I need to change the network, and if I want to use my TiVo to display photos, I need to change networks. I was hoping I'd still be able to get to that stuff since the 'g' network is hard wired into the ethernet port of the 'n' network. Oh well. I'm only on a 6MB Comcast service, so perhaps I'll try mixing the 'g' network in and seeing how bad it affects performance.
I'm getting 2.5 mb/sec on a hard drive transfer...can't imagine that being much worse on 'g'.

New Mac Mini and 802.11n 5Ghz - Does it work?

Does anyone know if this works? It states that it is 802.11a compatible which uses 5Ghz so I am guessing it does. I don't want to have to use a third party internal card like I do now with a separate external antenna. Thanks.

I have a mac mini I purchased last week (late 2009). I run 5Ghz 802.11n only (there is a g access point in the house, but that's on another part of the LAN). I have an iMac and MacBookPro that connect to the 802.11n and the performance is great - almost half as fast as a direct USB connection - it simply flies.
However, the mac mini is abysmal. It connects fine - everything works, but I get hardly 1Mbyte per second., despite having full signal strength. This is the info in System Profiler:

Apple TV refuses 802.11n

Howdy folks...
Bad week for Apple products for me. I went through two iPhones and now my Apple TV has decided to downshift! In the middle of watching a movie, the screen went black and came back with "Your iTunes Library is unavailable, make sure *computer name* is on and iTunes is open". I went over to the main computer and sure enough, iTunes was on, open, there were computers showing up in the shared section, but the Apple TV was missing under Devices.
I'll describe my setup:
I have a main file server in the house with the master iTunes library, it's the only library Apple TV syncs with. Connected to the server's ethernet port is an Airport Extreme N in bridge mode (one of its LAN ports), also, there is an 802.11 G "UFO" Airport connected to one of the spare LAN ports on the new Airport (this is the primary base station that is connected to my modem). I designed the network this way so that I can get the full 802.11n speed to my 802.11n devices (black MacBook and Apple TV), and other 802.11g devices would have their own portal into my file server. All Macs in the house run OS X 10.4.10 with iTunes 7.3.1 (I'm a freak about versioning)
I navigated to the Network section of Apple TV's settings where I noticed it was no longer connected to a wireless network, and in fact wouldn't scan or display ANY networks (there are about 25 within range of my apartment that I ALWAYS see), so there was no possibility of me rejoining my network, even manually. I realized the situation was crappier than I thought and would require some hard-resetting and restoring. Here's everything I did:
Factory reset Apple TV
Factory reset BOTH Airport Extremes (G & N) and set them up with NO security
Reinstalled iTunes, re-imported entire library
Turned Syncing off, then back on (I could only enter the pairing code when joined to 802.11G)
I discovered that after the restore, the Apple TV's Network utility on first boot would see my base stations! However, it would only join the 802.11G network, it continuously errored out when attempting to join the 802.11 N network (either -6, -3 or 0 as a code, which I couldn't find documentation for). Mind you, my MacBook can join my 802.11 N network with no problems at all, both before and after the factory reset of the base station. After I got the error code, and I went back to try and join my 802.11 G network, all the within-range networks were gone, and the scanning no longer worked as I described above. So I had to factory restore AGAIN. When the Apple TV came back up, I joined my 802.11G network with no issues, the Apple TV popped up in iTunes and began to sync. I cancelled the sync and ran the Software Update to get me to ATV 1.1. When it rebooted, I tried to switch networks and got the same loop of errors - try to join N network, fail, then no networks at all are displayed.
Does anyone have any further recommendations for troubleshooting, or is the wifi card in my Apple TV fubar? I'd imagine that would be covered under the 1 year warranty, but since I got the Apple TV on launch and more than 90 days has passed, AppleCare refuses to speak to me (an ex Apple employee, a current Apple certified technician, in the Apple Consultants Network, and Apple Store business liaison for small/medium business in the Bay Area....what nerve!) even though I never used my "one phonecall".
I've been really disappointed with their customer support as I've seen many of you on the boards have been as well, so hopefully we can help each other!

I know it's a lot of work, but you could try setting up your network and tv again, using entirely different criteria, ie new network names, device names and passwords. I'm not guaranteeing success, but I have seen networking devices behave as though they remembered passwords and names after a reset and have conflicted with a new set up using the same passwords/names etc.

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.

X1 and 802.11n

Hi,
Im having real issues with 802.11n and my new x1 carbon.
After configuring the '802.11n mode' option to enable I sometimes hit speeds over 54mbs but mostly it settles around 19-36..
This occurs at home and at my workplace (Technicolor gateway router and cisco enterpirse 802.11n network respectively).
What gives. I have updated the wifi controller to latest drivers.

When the iPhone joins the 802.11n (b/g compatible network) in the 2.4GHz band, the network will drop down the speed a little to deal with the slower device (this is done automatically, you don't have to manually change it).
Alternatively, you can manually switch between 5GHz 802.11n and 2.4GHz b/g mode every time your iphone need to connect to the internet. But it's a lot of inconvenience.
The best way is to run all 802.11n devices in 5 GHz band, and your iPhone in a separate 802.11b/g 2.4 GHz band network. But this requires two base stations.
From your earlier post, I don't think you have two base stations needed to set up a dual-band network, and you will need to purchase additional new base station to set this up.

Connections dropped, DNS and server timeouts from new Lenovo with 802.11n

New Airport Extreme, works great with Windows XP machine ethernetted into it, and also with a MacBook with wireless-N.
But my brand new Lenovo T60P with wireless-N is flakey with the Airport. It connects fine with a 100% signal, using the WPA2-PSK / AES setting on the Lenovo (WPA2 Personal security in 802.11n b/g compatibility mode on the Airport). Most of the time it works quite well.
But very frequently (every five minutes?) one of two things will happen: with the signal still registering fine in the taskbar (and in the laptop's wireless "status" utility), it will become unable to locate any website, including google.com, etc., and refreshes of currently-displayed websites yield server timeouts. The browser (firefox) gives a DNS timeout message. The second thing is just your basic dropped wireless connection. It will reconnect by itself after a while.
Any advice is hugely appreciated. It ***** to "upgrade" to headaches! (Ha! the forum software doesn't like a synonym for "vaccuums". Apologies to the nuns at Apple for my potty mouth.)

What you experienced is not a surprise as 802.11n is not a standard yet and each manufacturer has developed it own "pre-n" version. Right now Apple (base station) will work with Apple (notebooks), Dlink (routers) will work with Dlink (PCMCIA cards), etc.
Lenovo is no different. You can expect 80-90% compatibility, but not 100%. To expect cross-vendor 100% compatibility, you will likely have to wait until 802.11n is "approved" and then the firmware is updated on all devices.

Adding 802.11b/g AX(s) to multi-Airport Extreme 802.11n roaming network

First, a thanks to folks like Tesserax and Bob for the great ideas on this forum -- the questions & answers I've read have helped me to date, though I still have a question!
My home wireless network today consists of:
One fifth-generation AEBS running in 802.11n only (5 GHz) / 802.11n only (2.4 GHz) mode, on channels 149 (automatic)/11 (automatic) -- provides DHCP services
One second-generation AEBS running in 802.11n only (5 GHz) mode, on channel 157 (automatic) -- bridge mode
There is a wired home network with Cat5e and a gigabit switch in the basement. 30 down/5 up DOCSIS 3.0 service through Time Warner Cable, upstream from the fifth-gen AEBS. The AEBS units are connected in roaming mode via Ethernet.
Using the Airport Utility on my iOS devices, I'm getting "excellent" (59-65 Mb/s) connectivity when I am near either of the AEBS units. It is a large brick house built in the 1920s, and while there are now no dead zones in the house, there are areas where I drop down to 10-15 Mb/s per the Airport Utility. Unfortunately, the two AEBSs are at opposite ends of the house near external walls, one on first floor and one on second -- and the first floor rear AEBS needs to be where it is to serve a breakfast room and sunroom, while the home office AEBS needs to be where I have two Ethernet drops as the cable modem and switch are in the basement.
Before I added the fifth-gen AEBS, I had the older AEBS and two 802.11b/g Airport Express (AX) devices, also in roaming mode. I wasn't thrilled with performance, and while performance is much better with the two AEBS model, I'm wondering about the benefits of redeploying my AX devices elsewhere in the house on the roaming network -- on the theory that I should be getting better 802.11g performance from a device close enough to get max speeds than I am from a farther-away 802.11n AEBS.
However, I am concerned about whether adding back in 802.11b/g devices on 2.4 GHz would restrict the performance of my 802.11n network? I am assuming that might happen because I have 802.11n running on both frequencies... if I stepped back on the fifth-gen AEBS to 802.11n only (5 GHz) / 802.11b/g [or a similar setting] on that device, will that help? Or, am I running the risk of other cross-talk or interference -- or simply of my home network devices being befuddled by multiple access points in a single house?
Alternatively, I could try to replace my 802.11b/g AX units with 802.11n ones -- howeever, having just bought a new AEBS this week, that would encounter cross-talk with my Spousal Budgetary Compliance Unit (SBCU) and I could end up crashing the entire household....
Thoughts and ideas appreciated!

If you use the "b/g" AirPort Express devices in a roaming setup, any computers, iPads, etc in close proximity will connect at maximum "g" wireless speeds.
It's really not possible to predict the actual results in advance. The increased wireless coverage might tend to compensate for the lower speeds that would naturally occur due to signal drop off if you did not use the AirPort Express devices at all.
As long as the wireless access points are in a separate room, or separated by 25-30 feet or so from other access points, there should be no confusion that occurs with your laptop trying to connect. It will pick the strongest signal as it moves through the house.
I think the bottom line here is that this is one of those things where you just will not know unless you try. If the Ethernet cabling is already in place, it should not take long for you to find out how things are working.

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.

How to get 802.11n speed for Apple TV?

I installed my first Apple TV yesterday. Great stuff!
My iTunes movie library is on a Core 2 Duo MacBook Pro. I have not yet used the AirPort Extreme 802.11n Enabler on this MacBook, since I just found out it exists. If I use it, can I utilize 802.11n sync speeds with the Apple TV? How?
My AirPort network uses only an "old" 802.11g AirPort Extreme base station, not the "new" AirPort Extreme base station with 802.11n.
I have three 802.11g AirPort Express base stations on my network, mainly for using AirTunes.
My iMac connects to my wireless network using 802.11g, and I don't think the 802.11n Enabler works with it.
My cable modem current connects to my Airport Extreme (802.11g) base station via Ethernet.
I understand I can get a new AirPort Extreme 802.11n base station to replace the 802.11g one, and that would let me use the higher 802.11n speed from the MacBook to the Apple TV. It would also allow (unless I misunderstand) all my 802.11g devices to access the network at the lower speeds they are capable of. Correct?
I also understand there is something called a "dual band network" that involves using both base station types in one large network, but I don't know what the advantage of doing that would be, compared with just replacing the old base station. Can someone fill me in on that?
And, is there any way to get 802.11n speeds from the MacBook Pro to the Apple TV without getting an 802.11n base station?
Thanks in advance.

No. Unless you set up an adhoc network between your Mac and the Apple TV.

Yes, it would.

If you set things up this way, then I believe you wont be able to use wideband mode on the AEBSn. Your AEBSn will be opperating in mixed mode and its 802.11n performance will be degraded. The best set up would be to keep your old router to service the G only devices, and have your new AEBSn service the N capable devices. This would allow you to take full advantage of the performance increase provided by 802.11n capable devices.

How to Set Up AirPort Extreme 802.11n only Network

I purchased a used AirPort Extreme base station and a used AirPort Express off eBay to upgrade my home network. Both are the latest model AE (dual band II, firmware 7.5.1) and AX (802.11n, firmware 7.4.2). I want to use my AE as main router (Internet connection, DHCP) and use my AX to wirelessly extend network to my family room, where I have my Xbox accepting only wired network. And I want AE and AX to communicate through 802.11n to maximize bandwidth. Sounds easy right?
Well, I've got this set up mostly working except the 802.11n part. Not matter what I do, It seems only operating in g mode. I made my AE creating a 5Ghz network but I couldn't find this network anywhere. Not on my iPad, not on my iMac.
I'm wondering if I have a defective AE. The seller on eBay told me he used the 11n network just fine. The router is still under warranty, I'm wondering if I should ask Apple for a repair? But since I'm pretty new to Mac in general, I figure there might be something I just missed and hence this post. Any help is greatly appreciated!

I do have an AX that extends the AE network. There is nowhere on AX that I can specify radio mode, once I specified it to extend a network. I assume AX talks to AE over the n network and then extends the network to be g compatible? Sounds really strange.
Maybe not too strange. Since the AX is a single-band device, it can only extend the AEBSn's 2.4 or 5 GH radio, at a time, not both simultaneously. Since your iPhone was able to connect, most likely, it was extending the 2.4 GHz radio ... which was also configured to support "g" devices. What I haven't figured out is how, if you set the AEBSn's Radio Mode to "n only" why non-"n" are still able to connect when the network is extended.
... I chose to create a different network name for 5Ghz radio as something like: MID-EARTH (5 GHz). However I can't seem to find this network anywhere. I'm wondering why this is the case? Is my AE somewhat defective?
This may be a completely different issue than the extended network one. If you remove the AX from the network equation, wireless clients should see two different Network Names or SSIDs ... one being "MID-EARTH (5 GHz)" and whatever you called the 2.4 GHz network. That is, assuming that the client is capable of accessing both bands. If this is not the case, we would need to revisit your AEBSn's configuration settings.
