New Airport N network limited to 3.7mb/s - slow N performance

I recently purchased a new airport extreme and express to replace my older G equipment.
I have the extreme connected to my dsl internet and a few computers. The express is in a different room and is in wireless-bridge mode with a computer connected to it. So basically, I've got two rooms pretty far apart that I didn't want to run an ethernet cable between, so the express is acting as my internet bridge.
The extreme and express are the only wireless networking devices used and they are set to 802.11n only, 5ghz.
When I transfer a file between a computer connected to the extreme and a computer connected to the express, I get an average of 3.7mb/s (Wireless N should provide around 8-11mb/s).
I've tried the following things:
- I've transferred files through ethernet between the same computers (obtained 50mb/s)
- Had the express in the same room as the extreme and still got 3.7mb/s
- tried 2.4 ghz mode, g mode, robust networking on/off, wide channels on/off, security off, NAT off (on the extreme), and still got a max of only 3.7mb/s.
Either there's a setting I'm not seeing, or I'm starting to think that the WAN port of the express is limited to 3.7mb/s as it was primarily meant to be connected to an internet connection rather than a computer.
Anyone have any advice, or do you have a similar setup where you are getting more than 3.7mb/s between an express and an extreme?

This has been broken for a long time, I think. I have a similar setup, with two Airport Extremes (802.11n Fast Ethernet) each running 5GHz only on wide channels, one wired to the broadband and my network storage, the other wired to various bits of my entertainment system including a Mac Mini. They are only about 4 metres apart though there are some walls in between and for various reasons it's not practical to run cable without a lot of fuss.
I am using Airport firmware 7.1.1 and getting 9-10MB/sec between the two, which is great. I'm still using the old firmware because every update since then has dropped the network speed to the magic 3.7MB/sec.
When the Gigabit version of the AEBS came out I bought two to replace the old ones. The Gigabit removes one of the internal limitations of the Fast Ethernet, meaning that streaming from a single AEBS to say a Macbook is a bit faster, up to 12MB/sec over the same distance. But it has no effect on AEBS to AEBS transfers, which are still limited to around 3.7MB/sec.
Of course, the Gigabit AEBSs can't be downgraded to 7.1.1, so I sent them back to Apple. Luckily I'd kept the old Fast Ethernet versions, which are getting pretty old now but are still twice as fast as the newest hardware running the latest firmware.
I don't know what Apple have done to limit AEBS to AEBS speeds like that. It must be a firmware issue starting with 7.2. Maybe it was to improve reliability or something, but I'd rather have speed or at least the option.
If anyone has managed to get decent speeds between two AEBSs I'd love to hear about it, I'm pretty sure I've tried all the configurable options to no avail.

How to connect old aiport express to my new Airport Extreme? My Ipad says "base station e5713b cannot be configured" and my AirPort tool on my PC will not permit me to add my new Airport Extreme network (no network names to choose from)

How to connect old aiport express to my new Airport Extreme?
I have a PC running with Win7 and just replaced my Jensen With a brand New Airport Extreme.
I have set up the Airport Extreme to the internet, Iphones and Ipads and it work as it should.
I have downloaded latest Version of Airport tool on my PC. In addition i have downloaded the airport tool for Ipad.
I have reset one of my airport Express and it now shows up both on the Ipad and on the PC airport tool.
My Ipad says "base station e5713b cannot be configured."
I have wired the airport Express to my Ethernet to be able to "see it" on my Airport tool.
My AirPort tool on the PC will not permit me to add the airport Express to my new Airport Extreme network (no network names on the drop-down list to choose from). I wished for an easy set-up, but nothing seems to be plug and play as the Commercial says.. can you please help me?
Sigve

Hi
Thanks for Swift reply.
Yep - I in fact have two A1088 and one A1264
I actually bought the new router because the Jensen
router always lost connection to the Airport Express after some hours or days. I
always needed to restart my Jensen to play music and that was driving my wife
mad. The hope was that the Extreme should fix this. Both A1088 have been set up
to only stream music to two of my stereo amplifiers from my PC’s Itunes library.
Are the A1088 now useless?
The A1264 has been set up to feed internet into a Denon Reciever that needed Ethernet cable.
Please advise
Regards

Using my Actiontec modem's wifi, it doesn't find my new airport express. When I use the new airport express network I created error message says ip address is wrong. Help setting this new airport express up

Using my Actiontec modem's wifi, it doesn't find my new airport express. Using the new airport express network I just set up it says the ip address is invalid. What can I do to overcome this blinking amber light and error messages?

You need to begin by configuring the AEX to Join an existing network (Bridge Mode.) You can then connect to it using Wi-Fi, but the AEX will not extend your existing network.
If you can connect the AEX to your existing router using Ethernet, then you could use it to Create a new network. Otherwise, if you want to extend your existing network you will need to get a Wireless Access Point - WAP - from a non-Apple product like D-Link.

New airport extreme network very slow

I just bought the latest AE base station dual band, but am having trouble with the speeds. We have on the network:
1 macbook pro, 1 windows pc, 2 ipads, 1 ipad mini, 1 kindle fire, 2 iphones, 2 ipods (wow we have a lot of products I just realized now that I am writing them all down) a Wii console and 1 mac desktop computer. Oh and I have an airport express in another room set up to extend the netowrk.
Not all of them are on the network simultaneously.
Using the Airport utility (windows version) I have set up the network trying different configurations. Currently I have it set up as:
Radio mode: automatic
Radio channel selection: automatic
wireless security: WPA2 Personal
network options are 5 Ghz is unchecked
country is US
multicast rate: low
transmit power: 100%
WPA Group Key Timeout: 2 hours
use wide channels is checked
All devices can connect to the net, but speeds are at old dial up levels and that of course was NOT my intention in getting the latest router.
Any advice from those who understand things like multicast rate?

You either have a defective base station, it is not set up properly, or there is some form of Wi-Fi interference that is preventing your new AirPort Extreme from providing a clean signal.
What make & model was the router that you are replacing with the 802.11ac AirPort Extreme?

New Airport Extreme network won't hold stream to Apple TV

(I thought about posting this in the Apple TV forum but I think this is more appropriate here.)
For months I had a network configured in my home that included two Airport Express base stations. My cable modem plugged directly into one of them (in my office) and then both computers (G4 desktop and new laptop) shared internet, etc. via wireless. The other base station was in my living room to extend the network.
Upon getting an Apple TV many months ago, I began streaming my iTunes library that is stored on the G4: tens of thousands of files. I used this means of employing my Apple TV and listening to my music just about *every day*, for months. Streaming was always smooth -- never a hiccup, never an interruption, and I was thrilled by this new way of accessing my collection.
Recently, however, I replaced the office Express station with a new Extreme station, thinking it would possibly make the network faster as I could now connect the station back to the G4 via an Ethernet connection, now at least having one computer on the internet via a lined connection rather than wireless. And the new network works well in that aspect.
However, I can no longer stream any music to my Apple TV. It sees and accesses the library as it always has, but now just about every song gets choked up and drops the stream, no matter how I reconfigure the network (channel, transmit power, multicast rate, etc.).
Does anyone have any advice regarding how to make my network stable again so that I can resume streaming? I'm very disappointed that a major purpose for my Apple TV has been eradicated despite the fact that I thought I was actually upgrading.
Other factors could include the fact that within this time both the Mac OS software (10.4.10) and iTunes (7.3) have been updated by Apple. (I also wonder if the new Extreme station is too sophisticated for my G4, which maybe can't keep up with it, thus the choking?)
MacBook Pro 15" 2.33 GHz Core 2 Duo Mac OS X (10.4.10)

Such as
1) A network config issue. The G4 is still trying to
use Airport.
I have Airport shut completely off on the G4.
2) A software issue. The G4 is running a process
which is slowing it.
I don't notice any odd processes in Activity Monitor.
3) A hardware fault. The G4 has a hard drive with
errors, causing retries.
There are no notable errors on the drive but the whole process of accessing my iTunes library seems plodding and inefficient. The beach ball comes up a lot when accessing new parts of the library in iTunes.
Do a disk check.
I ran a disk check and defragmented not very long ago, so it should be okay.
Make sure software update is up-to-date. Reboot it.
I really thought today's iTunes 7.3.1 update would nail the problem, but it didn't... After 30 seconds, streaming stopped, Apple TV went back to menu.
Check Activity monitor for network speed, and
unwanted processes.
Nothing seems out of the ordinary.

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).

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.

802.11n networking via new airport extreme to airport express/ airtunes

Have been trying to include an airport express in my new 802.11n/ new airport extreme network, using new airport utility. Does not seem to work yet manuals/ the support site do not seem to rule this out. I would just like to stream itunes to remote powered speakers via airport express. Can I do this or do I have to wait for a "new" 802.11n airport express to be produced?
Thanks!
macbook (black) Mac OS X (10.4.9)

I don't have much experience in this area, but I can assure it's supposed to be able to work together seamlessly. So no you should have to wait.
Have you tried basic troubleshooting? (repair permissions, reinstall software, reboot, etc.)

Adding new airport extreme to an existing airport express network...

i currently have a home airport network comprising two airport express units; one attached to the cable modem in the bedroom and the other downstairs in my study (extending the existing network and feeding a shared USB printer and airtunes speakers). i've recently bought an airport extreme, to improve network performance. i also plan to add a NAS in the next week or so.
ideally i'd like to situate the new airport extreme in the study, as i don't want to have to keep the NAS in my bedroom!
my question is this, if i add the new airport extreme to the existing airport network, will i see the benefit of the 802.11n connection, or should the extreme be set up as the primary base station?

... will i see slower transfer speeds (than if it was connected to the extreme) to / from the NAS when accessing it wirelessly from elsewhere in the house?
No. The transfer speed will be limited by the slowest connection, which is almost certainly your wireless connection speed.
If you buy a switch, buy a gigabit switch. Not because a slower one will limit your transfer speed, but because the Extreme is Gigabit and any newer equipment is likely to be as well. The advantage would only be relevant to the wired LAN.
The Express's Ethernet is not Gigabit but there is no reason for it to be, since it cannot connect to anything other than a slower wireless connection anyway.

New Airport Extreme802.11n &Very Odd Network&Computer Issues

Hi,
We Replaced a D-Link DGL4300 802.11G and a Airport Express M9470LL/A with the most current Airport Extreme Base Station 802.11N 2.4Ghz and 5.0Ghz Dual Band and a Airport Express 802.11N (to use with a Shared USB HP1022 Laser Jet Printer. I have contacted Apple Tech Support once regarding setup and mentioned this other ? strange issue(s)
We have broadband cable that goes to a Motorola SB5101(meets ISP specs) then Ethernet cable
from Cable Modem to Wan Port on Airport Extreme. We have multiple computers all with wireless capability 1) Imac 800mhz 874 mb ram 802.11bAirport Card 2) eMac 1.0 Ghz 1gb ram Airport Extreme 802.11bWireless Card
3) eMac 1.25 Ghz 1.0gb ram and a Airport Extreme 802.11bWireless Card* all running OSX Panther 10.3.9 *and each with 802.11B wireless cards 4) Macbook Pro bought Dec 2009 running Snow Leopard 4gb ram and 250gb HDand 802.11n wireless card 5) HP Tower xw4550 running Win XP Pro SP3 4gb ram 500GB HD and a 802.11G wireless card 6) Dell Mini Net Book running Win XP Home SP3 1ghz 1gb ram 150 GB HD and a
802.11n wireless card.
At first tried setting up the Airport Extreme with the Dell Mini as it met specs and (as of Yesterday) the Mac Book Pro is with one of our children at college but was able to set up setting up the Airport Utility and Hardware for both Peripheral Devices with the Mac Book Pro.
Then things got odd. All the computers were online (as well as two wireless "Live" capable gaming systems XBox360 and Sony PS3 , I did not check my eMac until the next day
and when I woke it from sleep (or started it) I got "You need to restart your computer"
? Kernel Panic , I ran Disk Utility, Tech Tool Deluxe, Apple Hardware Test and even Applejack. no change and while permissions were repaired Tech Tool Deluxe and The Apple Hardware Test showed no faults with anything, Tried PRAM. restart etc, then we had the other eMac 1.0ghz which has been unused since the Mac Book Pro arrived as a gift, Plugged it in , started it up, and got online, no black screen, even checked and responded to email, then restarted the (2nd eMac 1.0ghz) and the "You need to restart your computer screen came up!) once seems oh maybe, possibly its crashed, or dying out
but two side by side, No Way! , so we then isolated electrical outlets, to the extent with a 100 foot extension cord outside on our back breezeway, same thing. We even went and bought a new battery and tried it in both , no change, * Was able to shut off the airport card in safe mode, restarted and it functioned as a normal computer with airport extreme card off
*same with the 1.0ghz emac airport card off and restart and functions as a computer but no online access. We then moved one close to the Airport Extreme and hooked up by ethernet and changed the settings and Bingo no Kernel Panic Like screen and can get online, tried the other same thing! So currently the two eMacs sit side by side and we bought a long ethernet cord and it works on the table where it originally was,
I did mention this to the Apple Technician that called from Apple regarding a setup issue (as have 90 days telephone support) and he said *That there have been reports of where there are with a Guest Network (we had one set up and He had us remove it as He asked if we really needed it and I said no AND also with networks with computers with wireless cards 802.11b
and 802.11g computers on a network with the802.11n computers and a 802.11n Airport Extreme, he could not explain it any further, he suggested a possible 3rd party software incompatibilty : recent download (but have not done any on the 1.25ghz eMac and the 1.0ghz has been shut
off since Dec 2009. I am baffled , my Wife and I were seriously considering buying a new Imac to replace the 1.25ghz after the Black screen showed up, but when the other one did the same, and did the trouble shooting and then the ethernet connect we saved ourselves a lot of money (t would be nice to have a new Imac but $$ is not there)
and in the past week now (could be our ISP) our Internet connection has dropped off 4 times usually for 30-45 minutes but Friday 8-20-10 it was over 3 hours (yet our Cable TV came in) I will contact our ISP who handles both the broadband about the outages
and our cable TV has been fuzzy -grainy at times, I called Them Friday and their were no outages in our area (system wide) Now though (except with Win XP) that is our access to the Airport Extreme and Utility (it blinks orange off and on when the internet is down) the Airport Express has stayed green each time. I will contact Apple also as ?
is it the Airport Extreme (but its intermittent) channels are set to automatically if thats helpful data rather than set to a specific channel, its fairly rural where we live
I thought of buying Tiger but saw the extreme prices and I called Apple per a recent Apple Thread they did not have Tiger Retail(nor did I expect then to) but after discussing
the Emacs they said why pay so much for Tiger (and a lot are used) they said and went over both eMacs specs and I checked in detail online and called them back as it was in a "card hold" and bought Leopard 10.5.6 (as min of 512 ram, DVD drive (have a combo -drive) and a Power PCG4 which both are and I am now getting unused (non System) data off the eMac and backing it up as well and its job will be to be able to access the Airport Utility (Apple OSX Leopard 10.5.6 was $129.00 plus tax free shipping and it arrived yesterday so if settings need changed can do that (with Win XP the Airport Utility
was so different and after about 4 hours and no progress I stopped and switched to he Laptop the next day!
Has anyone experienced anything like this, I read up on both peripherals before buying and called as well to the Apple Online Store to make sure we could 1) set it up and 2) all computers specs were met to be able to a)use the network for online use and b)as well as shared printing from any and all computers and they do meet the specifications
* one last item , my Wife's Imac is also on via Ethernet, It asked for a WEP password and that was not a option in the Airport Utility set up ,only WPA-WPA2 Personal password-Security configuration
so She is not on wirelessly (though I know She has been as in the past, Her Imac was on a desk in the foyer ) That may have been with the 802.11b Apple Airport white dome and not the D-Link 802.11G router of which we had a lot of configuration issues
*I could be wrong and will read up on her specs via the Mac Tracker application or online
Many Thanks, Its so odd I did not want to leave out data etc but its a *long post and I apologize for that, I hope some one can send some light on this. On a positive avoided buying a new computer!
but makes no sense (at least to us)!

I too have a MacBook Pro (running OS X 10.6.6) and a PowerBook G4 (1.67 GHz, OS X 10.4.11) and an AirPort Extreme 802.11n. I configured the new AirPort Extreme Base Station N last week using the MacBook Pro and the PowerBook can no longer operate with AirPort on (Restart Computer message). A rep at the Genius Bar indicated that WPA2 encryption might interfere with the G4?? He recommended setting up WEP encryption, this is no longer an option using the AirPort setup assistant.
It would be very helpful to know how this original post was resolved. The G4 SHOULD be able to work with the AirPort Extreme 802.11n in theory, right??

Hi i got a new airport express for christmas and i set it up as per instructions ,i even give a static ip and wpa2 security ..the problem is is when i come to want to use it it says its not on my network and a orange triangle shows .when i reboot it works

hi i got a new airport express for christmas and i set it up as per instructions ,i even give a static ip and wpa2 security ..the problem is is when i come to want to use it it says its not on my network and a orange triangle shows .when i reboot it works..then if i leave it a while and try iy agian its disapeared of my network...i have a bt hub 3 ....any help please ..im not sure if itsa faulty express

I really don't have an answer for that one. I guess that while trying to get things working correctly, I would use the most basic monitor I had which in your case would be the Eizon using the Thunderbolt port and adaptor.
When you boot into Safe Mode the startup is quite slow, but you should get the Apple logo and then the spinning gear below it (release the SHIFT key when it appears.) Then after a little more time you should see a gray progress bar appear below the spinning gear. When that disappears the computer will startup to a login screen.

How do I unhide my network which I recently set up with new Airport Extreme?

I recently set up my new Airport Extreme. Then realised my Canon MX 410 was not seeing it on wifi network. I've been told I need to unhide the AE so the printer can see it. However, when I go into Airport Utility it is not giving me the option to unhide. I have tried connecting ethernet cable to it & turning off wifi, but this does not help.. Any ideas people?
Thanks....

I've been told I need to unhide the AE so the printer can see it.
Advice likes this sounds good.....IF.....you previously enabled the option to "hide" your network. Chances are, you would know if you did do this, but if you are not sure, you can check to see if the network really is "hidden".
Open Macintosh HD > Applications > Utilities > AirPort Utility
Click on the AirPort Extreme icon, then click Edit in the smaller window that appears
Click the Wireless tab at the top of the next window
Click Wireless Options at the bottom of the window
If the network is hidden, you will see a check mark in the box next to Create Hidden Network. If the box is not checked, then your network is not hidden...so there is no way to "unhide" a network that is not hidden in the first place.....and you might want to contact Canon support for help on how to set up your printer.
If you do see that the box is checked, then remove the check mark to "unhide" your network, click Save, then click Update and allow a full minutre for the AirPort Extreme to restart.

Set up DynDNS access through existing network with new Airport Extreme

Hey everyone!
I just can't seem to figure out what I am doing wrong here...
I am working with an office network which was initially set up with a Linksys router and a separate Linksys hub connecting two Macs and a network printer in one particular room. We added several new iMacs and for ease of connectivity, decided to add a new Airport Extreme base as one of the new iMacs is acting as a server for a database the other new wireless iMacs connect to. Also, all the machines need access to the connected network printers connected in various parts of the office.
What we have now is the original Linksys router -> Linksys hub -> Airport Extreme. Everything seems to be working fine this way but I do believe that both the Linksys router AND the Airport Extreme are distributing IP addresses, which I'm thinking, could be the problem. I set up a DnyDNS account just fine, assigned port # 8080 on the server iMac and also opened port 8080 on both the Linksys and Airport Extreme. I still cannot get through to the server via DynDNS however.
I am wondering if I should turn off IP distribution on the Airport Extreme and let the Linksys router handle all that? The software that the other wireless iMacs run to access the database on the server depends on the server IP address too, so will this need to be changed if the Linksys is handling IP addressing? How does the hub affect any of this... does it change or interfere with the addressing in any way?
Thank in advance for any ideas or suggestions!

It has no affect.

Will I be able to extend a dual band network from a Time Capsule 2nd generation with the new Airport Express on both bands?

My Time Capsule 2nd generation is the main accesspoint in my house. It resides on the second floor in our living room. On the first floor in our kitchen I have an fairly new Airport Express that extends my network on the 5 GHz band and allows me to stream music via Airplay. I had to choose 5 GHz since the 2,4 GHz band is interfered when using the microwave oven. However, we have a rather old house with loads of metal in the concrete walls and therefore the 2,4 GHz signal from the second floor proivded by the Time Capsule is hardly available on the first floor. Since all our iDevices (iPhones and iPods) operate at the 2,4 GHz band we sometimes don't have a proper wi-fi connection. I had tried before with another (older) Airport Express that only operated at the 2,4 Ghz band, but I could get a proper connection between the Time Capsule and the Airport Express. Therefore I think it would be the best solution if the new Airport Express would provide both bands simultaneously.
If I replace my existing Airport Express with the new one, will I be able to extend my network on both bands?

It sounds like you may have configured your Time Capsule to use a separate name for the 5 GHz network and then setup the Express to extend that specific band.
In order to extend both bands, the Time Capsule setup will need to be changed so that both bands are using the same name. In other words, you would uncheck the option for the 5 Ghz name.
Then, setup the new Express to extend the Time Capsule network.
This is the only way that they Express can extend both bands. It cannot extend both bands if you have assigned a separate name to the 5 GHz network since you will be forced to choose either the 5 GHz band or the 2.4 GHz band for the Express to extend.
How the microwave oven will affect this is not known. This will one of those things that you have to try in your home to know if it will work well, so it might be a good idea to understand the store's return policy before you buy....in case things do not work out as hoped.

Can you add new AirPort Express Base Station Simultaneous dual-band 802.11n with a 1st Gen time capsule network

Hi
Has anyone tried using the AirPort Express Base Station with a first generation Time Capsule and used it to extend their network, while still being able to use the Simultaneous dual-band 802.11n on their network?
Thanks in advance

The first generation Time Capsule was not a simultaneous dual band device.
If you add the "new" AirPort Express to the network and configure it to "Extend a wireless network", it will extend the one single band signal that it is receiving from the Time Capsule.
In other words, the AirPort Express will not extend simultaneous dual bands in this type of setup...since it can only "extend" what it receives. You would need a simultaneous dual band Time Capsule if you want that type of functionality.

After the Airport update today, Airport Utility no longer sees my new Extreme or my 2 new Airport Express relay stations (same network); however, my internet is working and all Airports are green?

After the Airport update today, Airport Utility 6.0 no longer sees my new Extreme or my 2 new Airport Express relay stations (same network); however, my internet is working and all Airports are green? I'm running Lion on my iMac and updated when Airport Utility prompted me to do so a few hours ago. After applying the updates is when Airport Utility stopped seeing my routers. But they are working? Thoughts?

Did you remember to completely power cycle the entire network?
You would want to do this after any update or change to the network.
If you did not do this yet......things are out of sequence.
Power off everything on the network.....all devices.....power down order is not important
Wait a few minutes
Start the modem first and let it run a minute or two by itself
Start the next device connected to the modem the same way
Work your way out on the network starting each device about a minute apart
Check the network
