How to set up existing airport extreme on new modem

I have had to change modems and my Airport extreme will not connect to the new one. What do I have to do to make a connection to the new modem?

Given what I've seen in the forums, as of last night I'm experiencing a common result of going to Mavericks: my Airport Utility doesn't recognize my Base Station Extreme (or express) hardware or the networks set-up on the hardware. I bought and installed the Base Station unit in September, so it's not a hardware-too-old-for-Mavericks situation. Although there seems to be some strong opinions about the 6.3.2 utility, all I've been able to find are complaints, not solutions to the issue using the Mavericks package.
All the network hardware (router and modem) were running while I performed the Mavericks upgrade. Reading your post makes me wonder whether going through the reboot you describe in that Airport User Tip is the solution. The need for a fresh start triggered by new hardware may also translate into a need triggered by a new operating system.
Before I go through it, do you have any thoughts/suggestions?

How to set up multiple Airport Extremes with 1 SSID

Equipment:
     Office with 2 floors
     1 Modem
     1 Router
     1 Switch
     5 Airport Extremes (2014 models, each in Bridge mode)
Network layout:
     Modem -> Router -> Switch -> 5 Airport Extremes
Current Setup:
     Each Airport has their own unique SSID (ex. 1st Floor - Conference, 2nd Floor - Content, etc.). Connectivity is fine with this setup, different users join the closest Airport/SSID to them. Only issue is that user needs to switch to different SSID's as they move around the office.
Objective:
     Set each Airport to the same SSID so people don't need to switch to different SSID's as they move around the office.
Problem:
     I attempted to set each Airport to the same SSID. No issues with the setup, everything looks good in Airport Utiltiy. The problem is that some users connect with no issues, but when other users try to connect, they are asked to input a password, which is repeatedly rejected (even though the passwords are set up correctly on all Airport Extremes, and input correctly on all devices).
     I think this has to do with the 50 wireless user limit on the Airport Extremes, it looks like an Airport is maxed out at 50, and when a device tries to connect, it is rejected. I looked for a way to limit the wireless range on each Airport, but no option exists in Airport Utility.

Don't know what kind of main router that you have, but try setting the DHCP Lease Time to 1 hour if it is not already set to that limit.
If it is already set to 1 hour, lower it to the next available setting and update the router.
Then power off the entire network, then power up the main router first, and let it run a few minutes, then start the AirPorts one at a time about a minute apart.

How to set up my airport extreme to share my net connection. i have a ethernet cable from my isp which when i use in my mac, i have to enter username

I access net through ethernet cable from my isp. so i just plug in the cable in my mac and in the browser it put the username & password. now i want to use my airport express to create a wireless network so i can access net from ipad and mac simultaneously. when i use airport express both my mac & ipad gets connected to airp exp but each of them ask for isp's username and password. i can only login from either one of them and access net in that one only. Pls advice???

To allow your Mac to "see" the HDD attached to an AirPort Extreme Base Station (AEBS) that is configured as a bridge, just be sure to assign a static Private IP address to the AEBS. By default the AEBS is a DHCP client and will get a dynamic IP address from the upstream router that is acting as the DHCP server. Since this address can change over time, it would make it more difficult for network clients to find the HDD.

How do I connect my Airport Extreme to my modem (Cisco Model DPC3010)?

I am having trouble connecting my Airport Extreme Wireless Base Station to a Cisco Modem (Model DPC3010). I have used the Airport Extreme for years with other modems with no trouble. Alas, this time around I can't get it to work. I think I might not have the cable connected correctly. Help, please. Thanks

New Set up of Airport Extreme with New Macbook and 'Old' Mac Mini

I have wirelessly connected my new Mac Book to Airport Extreme, and have tested the connection by using a shared printer. I have connected my old Mac Mini (OSX 10.3.9) via Wired LAN.The MacMini does not recognise a connection to the Airport Extreme. I would like to share files between the MacBook and the Mini, but they do not 'See' each other. What have I not done correctly?
Mac Mini Mac OS X (10.3.9)

I have checked the IP addresses:
Mac Book nn.n.n.200
Mini nn.n.n.199
Airport nn.n.n.1
Al appear to be valid
A restart did not change anything.
I have been able to Ping each IP address succesfully from each machine, so the only aspect I can't understand is why each machine is not showing when I view the Network in Finder

Airport extreme with new modem

Hi All,
We just got a new modem when upgrading our internet service, and it'll work directly plugged into our Mac (though it seems annoyingly slow at first glance) but not through the Airport Extreme. My husband tried just going through the set-up process again, but it didn't seem like anything needed to be changed. The green light is on on the Airport, but we got nothin' for the laptops, Roku, printer, etc. (or even the Mac it's connected to if we have the ethernet cable in the Airport). The modem says it's an Westell ADSL2+ router, and looking at a few discussions here, it seems that that means it's a "gateway" not a modem?? What does that mean for our setup? Please go easy on me--I'm not good at setting stuff up! Many, many thanks!

UPDATE: AT&T sent us the new modem with our internet upgrade and we assumed it was necessary to use it. I tried everything: unplugging both in a variety of combinations, resetting passwords, finally starting over with the Airport factory settings and doing the setup (in bridge mode) from scratch. Nothing worked. I had finally come to the conclusion that AT&T's modem does not support Airport and we would have to buy a router from them. (The Westell is labeled modem+router, but I was unable to figure out how to get wireless directly from it.) Finally, after speaking with someone from AT&T, my wife just said "Why don't we just try plugging in our old modem." And...voilà! Back in business.
Moral of story: just because they send you new equipment doesn't mean you need to use it.

How do I setup my Airport Extreme so that I can extend the coverage of my existing AT&T wifi network?

How do I setup my Airport Extreme so that I can extend the coverage of my existing AT&T wifi network?

Start by establishing a permanent fixed Ethernet cable connection from one of the available LAN <-> ports on the ATT modem/router to the WAN "O" port on the AirPort Extreme.
Ethernet cabling can be run up to 300+ feet or 100 meters, so you should be able to locate the AirPort Extreme exactly where it will be needed to provide more wireless signal coverage.
Configure the AirPort Extreme to "create" a wireless network using exactly the same wireless network name, same wireless security setting, and same wireless network password that the ATT wireless is using.
The final step is to insure that the AirPort Extreme is configured to operate in Bridge Mode, so it will work correctly with the ATT modem/router.
If you need more specific steps, we need to know what operating system you are using on your Mac or PC. If you have a Mac and do not know which operating system it is using.....click the Apple icon in the upper left corner of the screen and then click About This Mac, and post back with the OS X version number that you see there.

How to set up 6th Generation AirPort Extreme to cable modem as a wireless router and then connect my 3rd Generation Time Capsule to AirPort Extreme as a wireless extender?

What is the best way to set up my 6th Generation AirPort Extreme (A1521) to my cable modem as a wireless router and then connect my 3rd Generation Time Capsule (A1355) to my AirPort Extreme as a wireless extender? I live in a small 1 story house and I currently have the Airport Extreme connected to my cable modem in the living room and the Time Capsule plugged into the wall in my bedroom. I am able to wirelessly connect to the internet using the AirPort Extreme as my router and I can also do wireless back ups to my Time Capsule. My problem is that my connection seems to be really slow! My 1TB Time Capsule back up is only half way complete and it has been 3 days! My computer has been backing up all day and night for almost 72 hours and its still not even 75% complete. I have backed up to this Time Capsule in the past and it never took this long. I am thinking that when I set up my AirPort Extreme and Time Capsule using AirPort Utility I must have set it up incorrectly or something.
How do I set up my Airport Extreme and Time Capsule for the fastest possible internet speed and back up speed?
Thank you,

AirPort Utility 5.6 works with AirPort Extreme 802.11g base stations.
It works with N version airports.
It will also show details of the AC model but cannot be used for the setup.. mostly.
I purposely got the new 6th Gen Airport Extreme so my internet connection would be a lot faster!
Your network will be much faster when you have AC client directly connected to the AE. Older client will go no faster.. but what is worse.. extend wireless is mixing new and old wireless standards.. guess what one wins.. OLD.. So when you extend wireless.. you have no improvement whatsoever. This whole post is about extending wireless.. so you cannot extend to older equipment and do any better.. maybe slightly better signal although from your comments that isn't happening either.
I would rather not have to use an ethernet at all with the TC and I don't know EOP adapters are!
If you do not use ethernet then you are going to be forced to accept slow speed.
EOP (ethernet over power). Also called homeplug in the US.
http://en.wikipedia.org/wiki/HomePlug
Provides a method of networking over power cabling that already exists in your house.
So what your saying is for the fastest internet speed and back up speed possible I should keep my Airport Extreme plugged into my Modem and keep my TC set up as a wireless extender? Then when I want to do back ups I should plug an ethernet cable from my TC to my MacBook Pro?
To spell this out.
A wireless link to an extended device will go very slowly.. if it is not direct.
So lets say you have a laptop sitting in the lounge.. Your connection goes.. Laptop- - - - - AE- - - - -TC.
That means two wireless links.. wireless has this nasty half duplex and single channel nature.. it can send or receive (Tx or Rx) but not at the same time.
Ethernet by contrast does both at once. It is full duplex.
Wireless can talk to one client at a time.. so if there are multiple items using wireless lets say 4 devices.. then your computer gets a 25% time slice. Since wireless cannot handle multiple simultaneous connections.
Ethernet by contrast can connect multiple computers to multiple destinations at the same time.. all transmitting and receiving at full speed.
When you put all this together.. there are a couple of rules for fast connection.
1. Use ethernet at all times. Where you cannot use ethernet use anything but wireless.. eg EOP (homeplug) at least to try and get rid of wireless.
2. Where you must use wireless use it sparingly and make sure it is never more than one hop.. ie never have an extend wireless (repeater is more usual term). Repeater will cause instant slowdown of 50% and maybe up to 75% just because it is so inefficient.
3. Fastest wireless is 5ghz but it has very short range.. you need to be up close and personal to get it working.
Apple routers however unless you do manual setup I suggest are set to connect to best signal strength not best speed. It will therefore use 2.4ghz at 25% less speed than 5ghz because it is 1db better signal.. this madness means you need to setup manually for the best setup.

How do I add an Airport Extreme with Time Capsule to an existing non-Apple network?

How do I add an Airport Extreme with Time Capsule to an existing non-Apple network? I have an ISP provided wireless Router that has to remain as the base station. I am able to join my 1/2TB Airport Extreme and Airport Express to the network, but I can't access/use Time Machine.

One option would be to connect the Time Capsule (TC) to the ISP-provided wireless router by Ethernet. You can then configure the for a roaming network. Then, depending on what your goal is for the AirPort Express, you can either: 1) Add it to roaming network, 2) Configure the TC & the Express for an "extended" network, or 3) Configure the Express to "join" the roaming network for AirPlay.

How do I add a guest network to existing airport extreme configuration?

I have an existing Airport Extreme configuation in my home Wifi network and I want to add a guest access point. When I open the recently updated airport utilities, the screen no longer looks the way it used to, with the side bar on the left and my devices listed there for me to select (I also have an Airport Express). I used to be able to select the Airport Extreme from the left side bar, then hit continue to change any settings. Well now, since it updated, the screen looks different, with internet at the top, pointing to the Airport Extreme, then the Airport Express. When I select the Airport Extreme, it no longer gives me the option to change the settings for it, which is where my problem lies! Any help? I know it's probably something very simple that I am missing, but I'm at a loss.

Why would I download a lower version of AirPort Utility?
To gain more functionality.....since AirPort Utility 6.0 is otherwise known as "AirPort Utility Lite" on the forums. It's a "first try" for Apple with a new look. While it does look nice, it has been downgraded as far as the features are concerned.
For example, if you open AirPort Utility 5.6 and click on the AirPort Extreme on the left, your Generation version will be displayed on the right side of the page. There are many more advanced settings available in AirPort Utility 5.6 as well...that are not available on 6.0.
But, you don't have to install AirPort Utility 5.6 if you don't want to. I suggested it because it offers more features and will also look exactly the same as the AirPort Utility that you have used previously.
If your AirPort Extreme is in Bridge Mode, this indicates that you have another device...probably a modem/router....which is acting as the main router on your network. Bridge Mode is the correct setting for the AirPort Extreme in this case.
If you can post back with the make and model number of your "modem", we can check to confirm.
Unfortunately, the Guest Network cannot be enabled unless you configure the AirPort Extreme to be the "main" router on your network, which is likely not possible. If you try to configure the AirPort Exteme otherwise, you will receive error messages and the network will not function correctly.

How do I set up my AirPort Extreme to provide IP addresses without being connected to the Internet?

II'm trying to set up my AirPort Extreme in the field without an Internet connection so that devises can communicate wirelessly but there aren't any IP addresses being generated

Just run the AE in router mode.. if you have difficult with the setup do it completely manually..
This is how I do it.
Airtport Utility can't find Airport Time Capsule on either of my 2009 Macs
As long as the AE is running in DHCP and NAT mode it will produce IP addresses.. however you cannot turn off WAN.
You could give it a static IP .. so set to static instead of dhcp if you like.. eg.
DNS and WAN errors.. double NAT, Ethernet unplugged, etc.. so it makes no real difference..
The AE will function fine as router (Wireless AP) to your network however..
Just ignore all the errors.
