Time capsule & airport express settings! HELP!!

Hi guys,
Would really appreciate some help. I have been running a time capsule with various devices and all has been going well. However there was an area of the house which the time capsule wifi couldnt reach so I bought an Airport Express to extend the network.
In Airport Utility, the Time Capsule has an error saying "conflicting DCHP range" and an error beside the Airport Express saying "Device not found." Ironically both devices are working (at the minute).
This is drivng me mental, if somebody could let me know what settings the two devices should be on regarding, DHCP, NAT and Bridge mode I would really appreciate it. Thanks in advance.

Fios Time Capsule Airport Express 101 Help Needed

I am trying to configure my network for the thirty-billionth time. I will start with my set-up, my goals and then my assumptions. If anyone has any thoughts, I am deeply appreciative.
Set-up
MI424WR-GEN2 router (802.11B/G/N; firmware: 20.10.7.5; henceforth "FR")
Time Capsule (First Generation 802.11N)
Two Airport Express (802.11N)
One Airport Express (802.11G)
All Airport Expresses are running 7.5.2
Right now here's how I have my network configured:
The TC and AEs are in bridge mode. The TC is connected to the FR by ethernet. Physically, the TC and FR are right next to each other. I have two wireless networks set up. One created by the FR which I have the radio set in "Compatibility Mode" , i.e., accepting 802.11B/G/N. The second wireless network generated by the TC, is set to 802.11N Only (5Gz).
Optimally, I'd like to have one wireless network, instead of two. I'm willing to ratchet down the 802.11N only to a more compatible setting to get down to one network.
Assumptions:
I cannot use my FR in bridging mode -- meaning it simply sends traffic to my TC which handles IP addressing, NAT, etc.
I cannot use my TC or AEs to extend my FR wireless network. And by "extend" I mean, use the boxes as signal boosters back to the FR. Physically, I have the ability, for instance, to move the TC from it current location to the master bedroom and connect it back to the FR via ethernet. In this case, I would like to be able to use the ethernet ports on the TC for some devices as well as use the wireless (single network preferablly) to boost the signal for some box-to-box applications I'm running as well as bandwidth intensive applications like Apple TV.
It is my understanding that it is impossible to extend a network with a TC or AE unless it is Airport network. It is possible to join a non-Airport network but I'm not sure what that buys you.
I am also under the assumption that the dual network configuration is impeding my ability to remotely connect to my iMac if it is running on the TC network which feeds back to the FR network.
I have read blogs that argue for simply shutting down the Fios radio and set the Fios router to bridge mode in essence and use the TC for all wireless. I have read blogs that suggest a plethora of different approaches.
I'm eager to figure this out and and promise to be responsive to questions and suggestions!
Thanks in advance,
JB

you're suggesting using both radios so both the FR and TC are broadcasting. if both devices are physically next to each other, is there any benefit in terms of range?
I must have misunderstood your earlier explantion about your desire to "extend" and thought that you were going to try to configure the TC to provide more wireless coverage for the FR network by locating the TC some distance from the FR router and connecting to it using a long Ethernet cable.
If you plan to leave the TC sitting next to the FR router, then there is obviously no benefit, range wise, and a probable wireless interference issue if both routers are broadcasting the same signals in close proximity.
The exception here would be if you plan to configure the TC as a 5 GHz band only while the FR provides that 2.4 GHz band. That type of setup is OK since both routers are broadcasting on different bands.
I remember reading somewhere that ActionTec doesn't play well with AE in WPA so I'll stick to WEP.
If you want to configure the TC to provide a 5 GHz band, you cannot use WEP security.....only WPA2 Personal or WPA/WPA2 Personal....will work with 5 GHz.
That means that the FR router must also be configured to use the same security settings. If it's not, then you will have two separate wireless networks with the same name and password, but different secuirty. That is bound to cause connection issues.
If you cannot match up the FR security to the TC, then it would be better to assign a different name to the 5 GHz network to keep things straight.
The other issue that you may face is if the TC is configured to provide 5 GHz, then that is what the AX"n" devices will try to extend. It's not easy to extend 5 GHz since the signals are quite a bit weaker than 2.4 GHz signals. You almost have to thave a line of sight relationship between the TC and AX devices for 5 GHz to be extended.
If you don't really need a dual band 2.4 GHz and 5 GHz network, then things would be a whole lot simpler if you turn off the wireless function on the FR router and setup the TC to provide a compatible "n/g/b" network, which the AX"n" devices will be able to extend.

Best configuration to extend wifi with Time Capsule & Airport Express

In my house I have a Fritzbox wifi router on the ground floor as my primary internet access. I have an ethernet cable going to the 3rd floor study where the Fritzbox signal is relatively weak. I purchased a Time Capsule as a backup device, but also wanted to extend the Fritzbox wifi network by plugging the ethernet cable in to the TC. I was not successful in extending the network, so I had to create a new network. When moving from downstairs to upstairs, my iphone keeps the connection to the (now weak) wifi network and I have to manually change to the (stronger) TC wifi network.
Additionally, I used to be able to successfully extend the downstairs wifi using my Airport Express (and also managed to have my speakers plugged into this for wireless usage), but do not want to additionally complicate my set-up.
So, what is the best way to connect the following equipment, ideally with the same network name, to ensure I always use the strongrst signal automatically:
Third floor:          iMac,    Macbook,   Time Capsule, Airport Express
          Ethernet cable from ground floor to 3rd floor
Ground floor:     Fritzbox wifi connected to internet

You must configure the Bridge Mode setting as the very last step before you Update the settings, otherwise the setting will change automatically.
In other words, you can change the setting to Bridge Mode, but if you make any other changes before you click Update, the Bridge Mode setting will not take effect.
Or, if you see any error messages about DHCP conflicts or Double NAT....the AirPort is not in Bridge Mode...even though you might think it is. Check the settings again.
will I still be able to set up an additional 5GHz network in parallel?
Yes

Time Capsule-AirPort Express-WDS not working together

According to everything I've read here, I've configured this properly, but it doesn't seem to be working. If anyone can help me troubleshoot this I would greatly appreciate it.
I have a new Time Capsule acting as my main wireless base station; it has a manually-configured static IP address, is plugged into my Verizon FIOS router, and is set to distribute IP addresses over wireless using DHCP. I have it set to run a 5 GHz network in addition to the regular 2.4 GHz network. I have an older AirPort Express that I want to use to extend the range of the 2.4 GHz network (the Express can only do 802.11b/g, not 802.11n), in part because we have some older devices in the house that I don't want to slow down the 802.11n network, and in part because the 802.11b/g signal doesn't reach all parts of the house very strongly. So I told the Time Capsule to make its network extendable, told the AirPort Express to participate in a WDS network as a WDS relay, and entered the MAC address of the Time Capsule's 2.4GHz network as the WDS main. Result: flashing amber light on the AirPort Express, which no longer shows up in the AirPort Utility; I had to do a hard reset in order to get the Express back (and then it had to be reconfigured again, of course). At the moment I have it just joining my wireless network, and that works -- green light -- but of course doesn't allow the Express to extend the range of the wireless network.
What am I doing wrong here?

Before there was dual band, we always told users that if they used WDS, the entire network would revert to "g", even if the Time Capsule, AirPort Express, etc were capable of "n" performance.
Your findings seem to confirm that this happens with a dual band as well.
I think it's well worth it to get the AirPort Express 802.11n. Then you can reconfigure the Time Capsule back to "Create a wireless network" and check the box to "Allow this network to be extended"
The Express"n" would then be configured to "Extend a wireless network". I use this setup and would highly recommend it. There may be a slight bandwidth loss due to overhead, but the performance is light years ahead of WDS.
If you are using the same network name for both bands on the Time Capsule, then I believe by default the Express will extend the 2.4 GHz "n", "g" and "b" band. This makes sense for most users since 5 GHz signals do not travel well over distance or penetrate obstructions well.
IF...you want to extend the 5 GHz band, the only way that I know how to do this is click Wireless Network Options on the wireless setup page for the Time Capsule and enable the option to assign a different name for the 5 GHz network.
Then you will have to configure the Express to extend this specific 5 GHz network. I never had much luck extending 5 GHz, and I wanted my iPhone to be able to use the network across the house, so I went with the simpler one network name for both bands and extended the 2.4 GHz network.
If you have a "g" device joining the extended network, it may tend to slow the "n" devices down slightly...when the "g" device is active, but it won't drag everything down to "g" levels. When the "g" device is not active, "n" devices will run at "n" speeds.
BTW, the ethernet port on the AirPort Express is active when you configure it to "extend a wireless network". This can come in handy for hooking up DVD players, etc that need an internet connection for firmware updates and extra features.
Follow up....I tried a very quick reconfiguration of my dual band AirPort Extreme (same router that the Time Capsule users) and AirPort Express using the WDS arrangement and everything did indeed drop way down in speed and performance.
Post back if you have questions. Happy to help.

Time Capsule + Airport Express N How to extend

Have been trying to extend my wireless network but have been unsussessful. Here is my setup. Cable modem connected to Time Capsule and Express N connected via ethernet cable. I try to do it with the setup but it will eventually revert to picking up the cable modem IP address 169.etc so I think I might need to manually input the addresses. Will some walk me through this including the ip addresses I should use? The Time capsule is NOT in bridge mode and works perfectly with the internet and other expresses used only for music streaming. Thanks

Mitchell, welcome to the discussions!
You may find it easier to use Manual Setup in AirPort Utility for the device.
The key setting would be under the Internet icon. Look at the bottom of the pane for Connection Sharing, this would be set to Off (Bridge Mode). Under the Wireless tab, you would set the Wireless Mode for "extend a wireless network" and make sure there is a check mark next to "allow wireless clients"
On the setup of the Time Capsule in AirPort Utility - Manual Setup - Wireless tab, make sure there is a check mark next to "allow the network to be extended"
If you have a good wireless signal in the area where the Express will be located, you also might want to try extending your network without using the ethernet cable. Normally, a good starting point for positioning the Express is at a point that is approximately half the distance from the Time Capsule and the area that you want to cover with the Express.
You may also need to reset your cable modem by powering it down for 10-15 minutes and then restarting.
Please post back on your progress.

Need help setting up WiFi - Xfinity with Network Switch, Time Capsule, Airport Express and Apple TV

Hello - I recently got Comcast Xfinity service. We had switched from a different service. Our wifi service was never great, but prior to Xfinity, it worked decently. But now that we have Xfinity, our wifi is much worse and very unreliable. I am seeking advice on how to setup my various Apple wifi devices in my home. I have attached a diagram that illustrates what I am dealing with. We have a large old house with stone walls. Comcast does not support this issue.
To explain the attached diagram, we have a total of 4 levels in our house - an unfinished basement, 1st floor, 2nd floor, and 3rd floor. The Xfinity router is in the basement and it is connected to a NetGear 10/100 network switch. I already have ethernet cables running from the network switch in the basement to various locations throughout the house. So I have ethernet connected to my time capsule and ethernet connected to each of my 3 Airport express devices. The dark lines running from the network switch to the various devices represents ethernet cable.
The immediate problem that we are having is that we are unable to connect to our wifi networks. The networks show on my mac laptop and my iPhone, for example, but I am unable to connect. I know that I am inputting the correct password, but most of the time, we cannot get in. Sometimes we can..... Very frustrating! Also, due to the fact that I setup what I have over several years, I have multiple network names. I once tried to fix that issue, but was unable to tackle it due to my lack of understanding.
Here is what I am looking to accomplish:
1. Seamless wifi access throughout our house.
2. One name for our wifi network. Right now we have multiple names for multiple networks. Just want to simplify and have only one network. (I guess that an additional "guest network" would be ok, but not absolutely necessary.
Also, if you think I should disable the Xfinity wifi, and just rely on my mac wifi devices, I am perfectly fine with this. Just tell me how to do so.
I have no idea how where to start or how to set this up. I imagine that I would need to disconnect everything and reset and start from scratch? Can someone tell me what I should do? Even general advice would be helpful, but the more specific, the better, given my limited understanding. Any help or advice would be greatly appreciated.
Thanks in advance!

Need help with new Time Capsule/Airport express setup!

I just hooked up a 500g time capsule to replace an airport extreme, and now my airport utility on my MacbookPro Retina no longer recognizes the airport expresses I had on my network for airplay purposes. Can anyone help with this issue?

Instead of a switch you need a wireless router, because your modem will only assign one public ip address to the switch and that ip address will be forwarded to any one computer at a given time...You should replace the switch with a wireless router and it should resolve your concern...

Time Capsule Airport Express Best Configuration for Backups & Internet

I have Time Capsule as a main router connected to a cable modem downstairs, plus Airport Express (new with firmware upgrade 7.3.2) in my office upstairs to extend the network. Two things keep happening:
1. Backups work sometimes and sometimes not although I am connected to my WPS secured network
2. Frequently lose internet connection, as in every hour or so; alternately nice and fast, then none at all. Most of the time I have a SNR of about 37.
Is there some optimal configuration settings for TC and Airport Express that could reduce these occurrences? Is there, for example, something I need to do with the Access settings on one or both?
Thanks for any help.

Since it still looks like you will need to support 802.11g wireless clients (your iPhone), the best radio mode for the Time Capsule (TC) will be the default "802.11n (b/g compatible." Since this is running in the 2.4 GHz radio band, you can use iStumbler (or similar utility) to determine if there are other Wi-Fis in the area; find out what channels they are operating on; and try changing channels on your wireless network to see if this will help provide the best SNR.
1. Backups work sometimes and sometimes not although I am connected to my WPS secured network
Are you actually using a WPS, or did you mean WPA?
2. Frequently lose internet connection, as in every hour or so; alternately nice and fast, then none at all. Most of the time I have a SNR of about 37.
If directly connected to the TC by Ethernet do you still lose the Internet connection periodically? If so, how about when connected directly to the cable modem?

Time Capsule & Airport Express (AX keeps disconnecting)

Hello! I added an Airport Express (AX) to the mix in July of this year so that my blu-ray player could access the internet. Everything works fine most of the time but the AX will periodically not have a connection and be blinking Amber until I reboot it (at least twice I've literally had to connect my MacBook to the thing and completely reset it because a reboot did not work). Here's my setup:
The Time Capsule is connected directly to my cable modem. The TC was purchased April 2008. I use the WPA/WPA2 (TKIP) encryption level, have a closed network, and have set it up to be the Main for a WDS network. The AX is the Remote in the WDS network. The only thing I changed when I got the AX was configuring everything for a WDS network.
We have four computers (Mac Pro & iMac and two MacBooks) and two iPhones, all of which connect to the TC without issue (via ethernet and/or wireless). Both the TC and the AX are running the latest firmware and all four computers are running the latest versions of Snow Leopard.
After having to reset the AX several times, I've wondered if it has anything to do with the WPA group key timeout. Neither of the device's logs give me a clue as to why it won't stay connected but I've incremented the WPA group key timeout setting to 30 days (I've toggled it up and down over the last couple of months for testing purposes) and now the AX works fine for about 30 days or so and then I have to reboot it. I've also tried changing the channel.
Since it works fine during the interim, I don't believe there's an interference problem (there are no concrete walls or appliances between them).
Any ideas? Thank you!

Thanks for the reply!
I actually did set it all up with the "Wireless Mode" setting as "Participate in a WDS network" instead of extending it. I don't recall now why I went that route. Perhaps I had trouble getting the "extend a network" feature working (I remember it was a bear getting the two working together).
I checked and, yes, the AX is "n" capable. I also noticed the radio mode on both devices show only "802.11b/g compatible" as an option. Is this because of WDS?
Would you have quick instructions on how to just extend the network and still keep my security settings intact? The other issue I have yet to tackle is that bandwidth tests over the TC wireless show way slower download speeds than upload but ethernet is very fast (and we see the result in games like World of Warcraft). I don't remember this being the case before but I can't remember the last time I tested it. I know that speed will be impacted with higher encryption and the use of firewalls, etc., but it shouldn't be as slow as it is.
Thanks, again, for all your help!

Optimizing Time Capsule + Airport Express configuration for best reception?

Hi --
I've been trying to set up a 1st generation Time Capsule with an Airport Express to extend the range of our wifi network in our new house (see http://discussions.apple.com/thread.jspa?threadID=2722259 for background).
As I understand it, the primary drivers for connectivity are:
1. Technical specs of the wifi hardware.
2. Physical positioning of the devices (base station or AE).
3. Configuration of the network (e.g. channels)
We don't have many options of where to place the base station, so I've been working with placement of the AE, which doesn't do much good. The issue seems to be the raw distance between the two devices, and possibly interference from other household items (e.g. wireless baby monitor, etc).
Is the a straighforward way to cycle through any of the configuration options to see whether that will make an impact? For example, I started cycling through the channel settings by hand, but that is very time-consuming as I have to wait for both the TC and AE to update, plus run back and forth between the base station and the laptop sitting at the other end of the house to trigger a speedtest.net run. Are there any tools or utilities that would help me with either the positioning or optimal configuration settings?
Thanks,
Ramon

The general rules of thumb for "extending" is that the AirPort Express should be positioned about 1/2 the distance from the Time Capsule to the area that needs more wireless coverage. This assumes there are no major obstructions in the signal path.
A typical sheetrock and 2x4 wall will absorb about 15-20% of the signal, on average. A ceiling will absorb proportionately more since it will be thicker.
Frankly, it's more art than a science to get an extended network working well. A quick test would be to power down the Express and take your laptop to the proposed area where the Express will be located and see if you can get a good, solid internet connection at that point. If you can, the Express may work at that position.
Users tend to place the Express much too far away from the main wireless router when they try to setup an extended configuration. When this occurs, the Express has very little to work with because.....this is very important to remember.....
+The Express can only extend the quality of signal that it receives.+ It does not "boost" the signal, it takes the signal that it receives and makes it go further.
If you want to download a utility like iStumbler, this can be useful to figure out a good location for the Express by "looking at the numbers"
But, there are never any guarantees with wireless. I wish that it were different, but unfortunately, no one can predict wireless performance in advance for any given situation. Post back if you want a few more pointers, or if you want to take a look at the Inspector feature in iStumbler.

Time capsule, Airport Express, iPhones

Hello,
I've tried another forum but could get an answer so I'm not sure if this is a Time Capsule problem but here it goes. I have a TC 1TB (Dual Band) as my base station that appears to be working fine and I have one new airport express that is extending the network.
I have a Macbook Pro that can connect anywhere no problem and can stream music over the AX.
However I have a couple of iPhones (3GS and 4) and having previously worked fine they suddenly can't connect to the network when they are only in range of the AX but can still connect when in range of the TC. All the firmware is up to date. I have reset the network but they still can't see the express. I have tried a bunch of different radio modes but to no lasting success. Sometimes an iPhone will connect but it seemingly kicks off the MBP!
Why is this happening and how can I sort it out?
Current Settings:
Wireless Mode: Create a Wireless Network
Allowing network to be extended
Radio Mode: 802.11a/n - 802.11b/g
Radio Channel Selection: Automatic
Wireless Security: WPA2 Personal
Country: UK
Multicast Rate: Low
Transmit Power: 100%
Using Wide Channels
Cheers,

It was connected at 2.4ghz.
The problem has randomly turned out to be a wireless TV transmitter. It must have been operating on a similar frequency to the iPhone's WiFi and therefore screwing up the signal in that part of the house (where the express is!).
Frustrating stuff but at least it is solved now.
Thanks very much for your help.

Time Capsule & Airport Express Extended Network loses connection!

OK, so I am an Apple virgin of 2 months experience, after many many years with Windows based PCs, so please be patient and gentle with me. Sorry about the long explanation.....
My set-up comprises of a Time Capsule, which is connected to the Internet via a NetGear ASDL modem. Both pieces of equipment are situated in my wife's office on the first floor of our house. My office is on the ground floor, where I have a 27" iMac and an Airport Express which is connected to a printer via the USB port. The Airport Express is sited about 10 feet from the iMac.
All software and firmware are lastest versions - TC v7.5, AX v7.4.2 & Airport Utility v5.5.
For the past 2 months, I have only been using the AX to print wirelessly and the set-up has worked faultlessly.
Earlier this week, I decided change the configuration to extend the network to allow me to use my laptop & iPhone in areas of the ground floor where I had no signal. I followed the online instructions and first changed the TC to check the box to 'allow this network to be extended', after updating the configuration successfully I moved to the AX. Here I changed the wireless mode to 'Extend a wireless network', selected the network name and checked the 'Allow wireless clients' box. This also updated successfully.
Everything ran correctly and the range of the network was greatly increased.......great, job done...not!
After about 3 hours the iMac lost the connection and the TC disappeared from the Airport Utility pane and refused to reappear. I checked but also couldn't connect or see any network on the laptop or iPhone, so have dismissed a fault with the iMac. I finally got things back up after doing a power reset of the TC, but after a few hours same problem occurred, and occurred and occurred. By clicking the Airport Utility icon on the top right of the screen and following the prompts from 'no Internet connection', I can at least get things up and working without a power reset of the TC, but the connection still drops after 2-5 hours each time.
My first call to Apple Support led to a full reset and re-config of both the TC and AX, setting the extended network up as I had done originally. The only difference was an iMac reset (alt/cmd P&R on power up) and changing the 2.4Ghz channel from 1 to 11. This had no affect and the connection drop-out problem continued.
My second call to Apple Support led to me being passed to a Level 2 Techie, who first suggested that I tried disabling the Guest Network - tried it, and it made no difference. I was then told to try a WDS network, which whilst not losing connection, is slower and has less range than the original extended network and frankly sounds a cop-out.
Has anyone had a similar problem, anyone solved the problems, can anyone offer any help or advice please.. I'd appreciate any input....thanks.

Similar problem here. Cable Modem (Moto SB6120)->AEBS (802.11n dual-band)>AX (802.11n) for wireless connection to MacBook Pro running Mac OS X 10.6.2. AEBS configured as dual-band: 801.11a/n at 5GHZ and 801.11b/g/n at 2.4 GHZ. AX configured to wirelessly extend the AEBS 5GHz 802.11a/n network. I am able to run on the extended 5GHz network (via AX) for varying lengths of time, until the internet connection dies. When this occurs, I am able to switch over to the 2.4GHz network to get back online. Solution up until now has been to unplug the AX, then plug it back in. After the AX restarts, I am able to hop back onto its 5GHz signal and get to the internet. However, the internet connection on this band will drop again after some time.
I was on the phone with Apple Support twice in the past week to get this resolved, but no joy. Senior Advisor seemed to think that my AX was working properly, and that that the problem could be with my AEBS -- perhaps the 5GHz antenna might be bad in my AEBS? Seems odd to me, since both my AEBS and AX are less than 2 months old...
I just read the post from LocoDoc and decided to see if I could replicate the problem. Sure enough, when I am connected to the internet via my AX extended 5GHz network signal and a Time Machine backup starts, the internet connection quits. Only recourse is to restart the AX. Note that I do not experience this problem with Time Machine while connected wirelessly straight to the AEBS 5GHz signal. Only when I am connected to the "extended" signal via the AX.

Best use Time Capsule & Airport Express together?

I've used the Express for several years and really enjoy using the ouput to play my iTunes wirelessly thru my stereo speakers. Then we moved, but my wife moved ahead of me and took the Express. I then bought a Time Capsule which doesn't have audio outs. I noticed that when I set it up it used the same name for the wireless network as my old Express. Now I've moved and joined my wife, and for the 1st time have both devices together. What is the most effective way to configue them? How do I maintain use of the Express for the iTunes wireless playing? Do I need to rename the network?

Hi Brian,
Set up your TC to be the Main network provider. It will work the best as it has the more powerful antennas. Then add the Express to extend the network of the TC. The Express will still play all music wireless and print wireless to printers attached. If you have both a APE g and n as i do its no problem at all couse the TC has got dual band.
For your last question, its best to reset the APE prior of doing the new settings. Just press the small reset button on the bottom of the device by pressing it for 10sec with a pen or pin (while attached to power). the light will start blinking very fast after 10sec. Then just plug out power and back in and your mac will see it popup in the airport utility.
Setup:
*First attach all cables to the TC and power it up, leave the APE off power.
*setup the TC as you pleaseand check if its works as you wish
*plug in the APE, airport utility will see it and ask you what to so
*set the APE to extend your existing network (that of the TC)
*APE will reboot and your off :-)

Extending airport wi-fi network (time capsule airport express)

I have a time capsule linked to my BT cable modem and i have created an apple wi-fi network that I use for my Mac mini and a laptop.
However the wi-fi network doesn't reach the other end of the house, and I am thinking about extending the wi-fi network by adding an airport express.
I have looked at the documents online, but I am not sure of a few things.
Do you need to wire the airport express to your time capsule or another cable modem? (that seems to loose the purpose of wi-fi) as per a document on apple airport networks (p41)? is the only solution a Roaming set-up?
Can t you just plug it in a electricity socket the airport express and add it to your wi-fi network via your network software in system preferences?
thanks for the help

Welcome to the discussions, stephanm8!
The AirPort Express(n) can be configured to "extend" the main wireless network created by the Time Capsule. Here's how to do it.
_On the Time Capsule:_
Open AirPort Utility, click Manual Setup
Click the Wireless tab below the row of icons
Wireless Mode would be set to "Create a wireless network"
Make sure there is a check mark next to "Allow this network to be extended"
Update to save settings
_On the Express:_
Open AirPort Utility, click Manual Setup
Click the Wireless tab
Wireless Mode would be set to "Extend a wireless network". If you don't see this choice, hold down the "option or alt" key on your computer when you click on the selection box. When you select this choice, you should see the network created by the Extreme to "extend".
Enter the wireless password if requested
Make sure there is a check mark next to "Allow wireless clients"
Update to save settings
If you have a dual band Time Capsule the main network can be extended. The guest network cannot be extended.
Once you have the Express configured to "Extend", position it at a point that is approximately 2/3 to 3/4 of the distance between the Time Capsule and the area that you want the Express to cover. You may need to adjust the location of the Express from this general starting position depending on signal strength.
