How do I create a wireless network using iMac as base station

How do I set up a wireless network using my iMac as the Base Station and boosting the signal through an Airport Extreme?
Physical connection would be DSL Modem> (ethernet) iMac >(wireless) Airport Extreme (as a wireless router for other Apple products i.e. TV, iPhone, etc.)

How do I set up a wireless network using my iMac as the Base Station and boosting the signal through an Airport Extreme?
Unfortunately, the wireless network that is setup from the iMac cannot be "extended".
Your setup will need to include two Apple routers and look like this:
                                                     > Ethernet to Imac
DSL Modem > Main Apple Router    >>>Wireless to nearby wireless devices
                                                     >>> Wireless to Extending Apple router
You may also connect the iMac to one of the Ethernet ports on the Extending Apple router if you wish

Extend an existing non-Apple wireless network using an Extreme base station

I have an existing wireless network via a Belkin modem/router. I would like to add my Airport Extreme base station to this existing wireless network, however this appears difficult. Can anyone help me please?

Hello IanWhite. Welcome to the Apple Discussions!
I have an existing wireless network via a Belkin modem/router. I would like to add my Airport Extreme base station to this existing wireless network, however this appears difficult.
Unfortunately, most non-AirPort routers are not compatible with Apple's implementation of Wireless Distribution System (WDS)...so it very unlikely that your Belkin router can be extended wirelessly with the AirPort Express Base Station (AX).
The few that are known to work are:
o Linksys WRT54G or WRT54GS (not v5)
o Belkin F5D7230-4 and F5D7231
o BT Voyager 2091
o Netgear WGR614 v6
o Buffalo WGR-G54
Is your Belkin one of the models in the above list?

Can't create a working Wireless Network using Airport Extreme Base Station

I don't know what I'm doing wrong...
I've got the cable from the modem going to the base station. I follow ALL on screen instructions. I select "Using DHCP" because when I plug the ethernet cable into my MBP it automatically does everything for me, and has that as its setting as well.
I get to the stage where it asks whether or not I'd like it to share an IP or go into bridge mode, I'm not sure what either of these two mean...I've tried both and both result in no wireless internet.
On several occasions I get to the end, and after I do the "final" update is comes back with one problem - internet connection, saying the router doesn't have a valid IP.
I'm totally lost on what to do here...
If you need more information just ask...please...

The below procedure is described in your AirPort setup manual, but it can be a little confusing. Here is my step-by-step procedure for an AEB setup for the system you describe:
A. Setup the 'Main' Base Station:
1. Do a factory reset of your AEB (main), then turnoff the DSL Modem and the AEB (main).
2. Check ethernet cable connections:
- DSL Modem > AEB (main) WAN port;
- AEB (main) > Mac computer running OS X 10.5.x.
3. Power-on DSL Modem and wait for it to initialise.
4. Power-on the AEB (main) and start your Mac computer.
5. Open AirPort Utility and select the AEB (main) in the LH pane. Click 'Continue' and give the AEB (main) a name and an admin password (twice). Click 'Continue'.
6. Select 'I don't have a wireless network and I want to create one', click Continue.
7. Give your network a name, select WPA/WPA2 Personal and insert the wireless network password (twice) - use 13 alpha/numeric characters for password. Tick 'Remember this password in my keychain'. Click 'Continue'.
8. Select 'I connect to the Internet with a DSL or cable modem using DHCP. Click 'Continue'.
9. Click 'Update' and wait for the AEB (main) to restart.
10. Disconnect the ethernet cable between your Mac and the AEB (main).
B. Setup Client computer
1. Open System Preferences/Network/AirPort.
2. Against 'Network Name:' select your network (the name you gave it at A7).
3. Click 'Advanced' and select TCP/IP. Against 'Configure IPv4:' select 'Using DHCP', then click 'OK'.
4. Click 'Apply' and exit System Preferences.

Creating a wireless network using several Airport Express(es)

I would like to connect three AirPort expresses to my Sky Broadband router to create a new wifi network in my house. My router is in the basement and is connected into a hub which provides ethernet to the house. I would like to connect the AirPorts via ethernet to the router and create a single wifi network.
Can someone please tell me if this is possible and what settings the AirPorts should have. For instance, should I just extend the sky network using each AirPort or should I create a new network with one AirPort and then extend that with the others?
Many thanks
Terry

If each of the AirPort Express devices will be connected using Ethernet, you would configure them all exactly the same except for assigning different device names...AX1, AX2, AX3, etc.
Each Express will be configured to....
Create a wireless network
Same wireless network name on all devices
Same Radio Mode
Channel set at Automatic
Same wireless security setting
Same wireless network password
Very important....configure each Express in Bridge Mode

How can I extend my wireless network using Airport Express and an Airport Extreme on BT Infinity?

I have BT Infinity and I am using the Time Capsule with Airport Extreme as my router. Working well (even on wireless). I want to extend the wireless network with an Airport Express, but I cannot work out the settings necessary in Airport Utility. I am using Mountain Lion 10.8.2 on a Mac Pro. Please help!

BT,
I've read several of your posts, thanks for taking the time to share your wealth of knowledge.
I'm in a situation similar to the one described by 'scoutusmaximus'. Seeking the flexibility of a standalone router, I finally upgraded my 4-yr old ATT DSL gateway (modem+router) to a Comcast standalone modem + the ASUS RT-AC66U: http://www.asus.com/Networks/Wireless_Routers/RTAC66U/
Typically, I stick with all things Apple but the ASUS router seemed fairly superior to the current-gen base station (on paper, anyway; time will tell when it comes to performance) so, for once, I jumped ship. My plan was to extend the ASUS wired/wireless network using my TimeCapsule and 2 Airport Expresses in bridge mode, however, a google search turned up several unhappy customers that claim those devices don't play well with non-Apple routers, especially when it comes to 'extending' a network.
Questions:
1. Can I successfully extend the wired/wireless network created by the ASUS router using the 3 airport devices listed above w/out negatively impacting performance? I'd rather have 1 wireless network as opposed to creating a new wireless network with the TC and then extending it with the AP Expresses... though I'd consider that option down the line if it came to that.
2. Will the LAN ports on the TimeCapsule remain functional?
Btw, my house is wired so, I can reach all 3 devices via ethernet cable coming off of a central, managed switch. Supposedly, you only lose the LAN ports on the TC if you extend wirelessly.
Any advice would be appreciated.

How can I create a wireless network in my office for my itouch?

I am in an office Windows environment with a G3 Mac that is connected to the internet via the Ethernet port. I can get to the internet with my Mac through a Proxy server. I have tried to setup up Airport to get through the firewall without any success. Is it possible to create a wireless network for my itouch if I install an Airport card in the Mac, start Internet Sharing and install Airport Express? I have no experience with the Internet Sharing options in OSX. I am assuming that my Mac with an Airport card would pass the internet connection to Airport Express. Airport Express would then create a wireless network for my itouch to connect to the internet. Any advice is appreciated as I would really like to get to the internet with my itouch.

You don't need the AirPort Express to do this.
You can set your Mac to share it's wired connection over the wireless port and the iTouch can connect directly to the Mac.
You could also do it with the AirPort Express, but you don't need to - it's overkill for what you've described.

Using iMac as base station

First, forgive me as I new to Apple (former PC).
I have the new iMac 27" i7 and was told that it has a built-in Airport Extreme. I just purchase an Airport Express and can't figure out how to get the AirPort Utility to recognize my iMac as the Base Station.
I have DSL (through ATT) hardwired from the DSL modem to my iMac. I would like to use the AirPort Express as a bridge so I can connect my Directv HD-DVR to the network, wirelessly.
I've heard that this is possible but I just can't get this to work.
Thanks

MrMetrx, Welcome to the discussion area!
I would not recommend doing this. You will get much better control and flexibility by using any inexpensive wireless router.
If you want your Mac to act as a base station, you need to go to System Preferences-> Sharing preference pane and enable Internet sharing to AirPort.

Can I network 2 iMacs without Base Station?

I have two iMac's with airport extreme cards in them. Can I network them together without having a base station? If yes, where can I read how to do this?
If I can network them together without the base station and just airport to airport in each iMac, can the one iMac without internet gain internet access if the 2nd one does have internet and the sharing feature for internet is turned on. My goal is to get internet access on a iMac in another room via and airport to airport connect with no base station.
Thanks
tj

To meet your goal, you can use Internet Sharing to share the wired Internet connection of first Mac wirelessly with the other.
To setup for Internet Sharing (Wired to Wireless):
Enable Software Firewall
System Preferences > Sharing > Firewall
- Click Stop to start the software firewall
Setup the Network
Cable Modem > (Ethernet cable) > [Ethernet port] Mac_#1 > (wireless) > Mac_#2
Setup Port Order
System Preferences > Network > Show > Network Port Configurations
- Verify that "AirPort" and "Built-In Ethernet" are enabled.
- Verify that "Built-In Ethernet" is at the top of the list, followed by "AirPort".
- Click "Apply Now."
Configure the Internet Connection
System Preferences > Network > Show > Built-In Ethernet > TCP/IP
- Configure IPv4: Using DHCP
- Configure IPv6: Automatically or Off
Enable Internet Sharing
System Preferences > Sharing > Internet
- Share your connection from: Built-in Ethernet
- To computers using: AirPort (checked) (Note: Uncheck all other entries in the list.)
- AirPort Options
-- Network Name: <anything you want>
-- Channel: Automatic
-- Enable encryption (using WEP) (optional)
-- Password: (optional)
-- Confirm Password: (optional)
-- WEP Key Length: (optional)
-- Click OK

How do I create extendes wireless network

Unfortunately my Internet line comes into the basement. I have a second generation APExtreme and it's not cutting it for the upper floors. So I bought the newest APExtreme and want to use the older one on the main floor as an extender.
Can someone please give me guidance? Or do you thik the new one will be sufficient with all the new antennas they put into it?
Thank you for any help.

Power off the older 2nd Gen AirPort Extreme for now and get the new AirPort Extreme in the basement installed and up and running.
I doubt that the new AirPort will provide the coverage that you want upstairs.....but anything is always possible. Give it a try and please report on your results.
If you want to use the older 2nd Gen AirPort Extreme as an extender, it will be need to be reset back to default settings and then reconfigured to work with the new AirPort Extreme.
The older AirPort must be located where it can receive a good wireless signal to be able to extend it....if you plan to connect wirelessly.
If at all possible, you would want to connect the AirPorts together using a wired Ethernet connection. This results in a much stronger signal for the upstairs AirPort.
Post back if you need some tips with this.
We assume that you are using Lion, Mountain Lion or Mavericks on your Mac. Is that correct?

I am FRUSTRATED! My goal is to create a wireless network using an iMac, a Westell 2100 modem (and router)

I started with a PC, the Westell 2100 modem (also a router) and the Linksys WRT54G. I set it up according to instructions I found on the Internet, and it worked fine for YEARS!!! Then, I switched to an iMac. After problems with the setup, I found help on the Internet, and got it working. It has been a long time since then, and I have had to disconnect things, and I do not remember how to set it up. I have searched the Internet, but cannot find a solution. I have searched the community, and followed some instructions here, but I have had no success. I know the following:
The Westell 2100 works as it should. I can connect directly to my computer and access the Internet.
The Linksys WRT54G has not been damaged.
At one point, I had set the SSID and had a WEP/WAP key that is HIDEOUSLY long. Here are some more tidbits: WPAPSK TKIP.
Please help! My new iPhone 4S(teve) needs it's wireless connection to Wi-Fi .

Pleeeze help???

Can't create a wireless network without a wireless card on my Mac

Help!
O.k. I tried searching the forums for an answer but the odd nature of my problem, and the immense database of topics made it very difficult to find a similar post.
The general issue/idea:
Run a wireless network using Airport Extreme - Connect desktop mac via ethernet and Roku player via wi-fi. Can't get the desktop mac to connect via ethernet when I restart the network/Airport Extreme.
My Father in law has my old computer; It's a PowerMac G5 (Dual 1.8GHz CPUs) running OS 10.5.8), connected to internet via cable (TimeWarner) modem. It does NOT have an Airport or Airport Extreme card installed. The computer works fine, and I don't believe that I 'need' an Airport Card in order to use the Airport Extreme (it's a brand new/refurbished model) in the manner described below.
I would like to use the Airport Extreme to generate/run a wireless network (Do I need an Airport Card in order to generate/run a wireless network? Doesn't the AE actually do that?), connect the desktop Mac to the network via Ethernet (I shouldn't need an Airport Card to do that, should I?) and connect a 'Roku Player (802.11g capable) to the network via wi-fi.
As far as I know, this should be possible.
Basic steps/as I understand them:
A. Connect ethernet from cable modem to AE.
B. Connect ethernet from AE to desktop Mac.
C. Create the wireless network using desktop Mac and Airport Utility.
D. Restart AE to start the wireless network running.
E. Connect Roku to wireless network over wi-fi.
I have no problems with A & B. Once the AE is connected to the desktop Mac, I'm able to get internet via ethernet as it passes through the AE. I can then create a wireless network (step C.) using the Airport Utility (and setup assistant). The problem starts after I've configured the wireless network.
Once I've configured the wireless network, the Airport Utility software prompts me to restart the AE in order to start the wireless network.
As soon as I restart the AE, my desktop Mac tries to connect to the 'wireless' network, even though it's already connected via ethernet. I don't have a wireless card in the Mac, and I don't want to connect the desktop using wi-fi/wireless. It's connected via ethernet, works fine during configuration, and I don't ever anticipate a desire to connect the desktop via wi-fi.
No matter what I do, I can't get the desktop to connect via ethernet. The only network connection option I'm offered is 'Rescan'. O.k. the desktop can't find the wireless network (because it doesn't have a wireless card), and I'm unable to continue with the Airport Utility. I can't make any further changes to the network (the options to manually change the network configuration are not available as the desktop Mac cannot currently talk to the AE - It's still trying to connect wirelessly), and the desktop has no internet connection as it's trying to connect wirelessly.
*How can I...*
*Setup/run a wireless network, while keeping the desktop Mac connected via ethernet?*
I'm perfectly willing to factory reset the AE and start over.
Any help appreciated.
Thwarted by the network.

My Father in law has my old computer; It's a PowerMac G5 (Dual 1.8GHz CPUs) running OS 10.5.8), connected to internet via cable (TimeWarner) modem. It does NOT have an Airport or Airport Extreme card installed. The computer works fine, and I don't believe that I 'need' an Airport Card in order to use the Airport Extreme (it's a brand new/refurbished model) in the manner described below.
That is correct, you could connect the PowerMac G5, via Ethernet, to the AirPort Extreme Base Station (AEBS) or any other wired router for Internet access. You do NOT need an AirPort Card for wired access ... ONLY if you want the G5 to connect to a wireless network.
I would like to use the Airport Extreme to generate/run a wireless network (Do I need an Airport Card in order to generate/run a wireless network? Doesn't the AE actually do that?)
That is correct, the AEBS is a wireless router that can provide a wireless network. The AirPort Card, on the other hand is a wireless adapter used to allow a Mac to connect to a wireless network, created by any wireless router ... not just those provided by Apple.
As far as I know, this should be possible.
Basic steps/as I understand them:
A. Connect ethernet from cable modem to AE.
B. Connect ethernet from AE to desktop Mac.
C. Create the wireless network using desktop Mac and Airport Utility.
D. Restart AE to start the wireless network running.
E. Connect Roku to wireless network over wi-fi.
Yes, these are all good assumptions.
As soon as I restart the AE, my desktop Mac tries to connect to the 'wireless' network, even though it's already connected via ethernet. I don't have a wireless card in the Mac, and I don't want to connect the desktop using wi-fi/wireless.
Do you actually have an AirPort Card installed in the G5 now? If so, then it might be possible that the "firing order" for network connectivity has AirPort at the top of the list under System Preferences > Network. Just change the order to have Ethernet at the top and disable AirPort to ensure that the G5 connects by Ethernet only.

Extending wireless network using Time Capsule

Hi guys,
I have been trying to sort this issue out for some time.
Basically I have a Thompson Wireless Router which connects to my ISP, this is downstairs broadcasting a wireless network to my house.
I want to put the Time Capsule upstairs, to extend the WLAN and also connect my Xbox over Ethernet.
No matter what I try I cannot get it to work, it ends up setting up 2 WLANs where the Thomson WLAN works (as there is an ISP connection) and the TC wont (as its not connected)
What I want is for the Thomson WLAN to be extended via the TC to allow my Xbox on to Live...
I also have a Mac Mini upstairs that would connect either via the TC WLAN or through ethernet.
Any help you can offer would be amazing
Thanks
Adam

If you are trying to "extend" the wireless signal from the Thompson router through the Time Capsule using wireless only, this is probably not going to work.
The reason for this is that Apple's "extend a wireless network" feature appears to be a proprietary technology that works only among other Apple devices. For that reason, it is highly unlikely that the Thompson router and Time Capsule would be compatible for the purpose that you desire.
If you are able to connect the Time Capsule to the Thompson router using an Ethernet connection, you could configure the Time Capsule to "create a wireless network" using the exact same wireless network name, security settings and password as the Thompson network. In addition, the Time Capsule must be configured as a "bridge" in Bridge Mode for this to work correctly.
If you cannot run the Ethernet cable, you might want to look at a pair of Etherent powerline adapters to accomplish the same task by sending the Ethernet signal over the existing AC powerlines in your home.

I just purchased the airport Express to use in hotels while traveling to create a wireless network from the hotels wired dsl. A friend said to set up the network from home prior to traveling. How do I set this up? Thanks.

In addition to RyanJC's comments, the 802.11n AirPort Express Base Station (AXn) can store up to five different http://docs.info.apple.com/article.html?artnum=108081 configuration profiles. You will need to use the AirPort Utility to create & save these profiles.
To create a new profile:
Open AirPort Utility, select your AX from the list, and then, click "Manual Setup."
From the AirPort Utility menu, select "Base Station," and then "Manage Profiles."
Click "+" to create a new profile; give it a name, and then, click OK.
Set options, such as network name, passwords, Internet connection method, etc.
When done setting the options, click Update.
To switch profiles:
Open the AirPort Utility, select your AX from the list, and then, click "Manual Setup."
From the AirPort Utility menu, select "Base Station," and then "Manage Profiles."
Click on the desired profile, and then, click OK to apply the new profile and restart the AX.
Just remember to switch to the desired configuration profile before removing power from the AX.

Can I create a unique subnetwork when extending a wireless network using Airport Extreme?

My office building has an Airport Extreme to provide wifi to our individual suites. I would like to create a sub-network using my Airport Extreme for my suite only that uses the wifi signal from our office building and provides internet to the computers (both wired and wireless) in my suite but have it protected so that other suites in my building can't see my computers. Is this possible and how do I do it? I have currently set up my Airport Extreme in wifi-mode "extending a previous wireless network" and have the router with its unique router name. But once I extended the wireless network, I could not find the network name of my router, only the office name (the one I was extending). The computers connected via ethernet to my Airport have internet access but none of my wireless computers see my airport name, it sees the office building network name. I'm assuming they are connecting to my Airport since the signal level is much higher than before and it appears that my Airport is rebroadcasting the network name of my office building. Is there a way to have my Airport broadcast its unique identifier for wifi, still connect to the internet via wifi signal to the Office building airport and maintain segregation between my computers and the rest of my office building?
Also, when I use the Airport Utility on my Iphone, I see the internet -> the office airport extreme -> and then 2 different base stations connected in a Y. Mine and my neighbors (who is probably doing the same thing as I am). But there is a dotted line to my base station, does that mean I'm connected to the internet via my neighbor's airport?
Any thoughts?

It is not possible to configure a single Apple AirPort router in this manner using wireless only, but it would be possible to do this with a single AirPort if you connect your AirPort Extreme to the "main" router using a wired Ethernet connection.
As for wireless only....you could probably do what you want by using two Apple routers....an AirPort Express to join the wireless network and provide an Ethernet signal to the AirPort Extreme's WAN port. Then the AirPort Extreme could then be configured to provide a separate network using a different subnet.
Users on the "main" network would not be able to "see" any devices on your "private" network and vice versa.
I use the two router set up all the time at hotels that only provide a wireless signal. The first Express "joins" the wireless network and feeds an Ethernet signal to the second AirPort which is configured to "create a wireless network" in router mode.
This way, I can connect multiple devices to my "private" network, but only pay the hotel for one connection since the hotel router only "sees" the AirPort Express that joins the network.

Using airport Express on a hotel ethernet to create a wireless network

Hi there, yesterday I bought an airport express as I was lead to beleive it was the perfect device and simple to set up with regards to creating a wireless network from a ethernet connection in a hotel room. I seem to get a green light and seem to aquire a valid IP address of 192.168.2.102 and the AE utility doesn't state I have any problems and yet I cannot connect to the internet. I am from the UK and currently in Honk Kong on business for the next few days and desperately need to get a wireless connection sorted. I have read through many of the archives on these forum pages and it is still not certain to me whether I should be using bridged mode or not?
btw, I can connect my pc and get internet access without any problems by ethernet directly into my pc.
can someone advise me of the settings I should use given my scenario (ethernet connection in a hotel room). Given how much tme I have invested trying to get the AE to connect to the internet I would prefer to stick with it and get it workShort rather than taking the Airport Express back to the Apple store tomorrow and moving to a hotel with wireless and not ethernet connection.
Help appreciated
Russellb

Hello, thanks for your suggestions. I have tried setting up the AE using my girlfreinds Win XP computer instead of my vista one and it setup 1st time without any problems. In fact, the options I got presented with were slightly different. Shocked at what a difference installation and setup can be from using a Vista laptop to a XP netbook. Maoin thing it is now working and you were correct about using it in bridged mode so many thanks.
