After resetting airport extreme, cannot connect to internet

Hi all,
Few weeks ago, my modem died so today I got a new one. Connected to Airport Extreme, it wouldn't work. I downloaded airport utility for windows (I am now using a window pc with airport) and did a reset and created a new network and none of it helped. The pc is seeing the airport but it just cant connect with the internet. I keep getting message that involves "double NAT"
Please help thanks.

A Double NAT error indicates that your "modem" is actually a router. Since the AirPort Extreme is also a router, you wind up with two routers in series on a network, which is a no-no.
The AirPort Extreme needs to be configured in Bridge Mode to work correctly with your "modem".
Open AirPort Utility - Click Manual Setup
Click the Internet icon
Connection Sharing = Off (Bridge Mode)
Update
Then restart your entire network

Airport problem-cannot connect to internet since update

I like many folks here is new to a Mac. I have a iMac intel duel processor. i apparently did this update to 10/4/8 10/2/06. Since then airport does not work and I cannot connect to internet at all. I have talked to Apple customer service but so far no help there. They want me to reinstall disc that came with computer. I also have a new MacBook that has update also. I can set it beside the iMac in my office and it works great. We have a wirelss system in our home and a PC and the MacBook still connect with no problem. Settings on iMac and MacBook look identical to what I can tell. Nothing I try to connect works, rebooting, change some setting. Can anyone offer easy to follow suggestions to a new Mac user. Thanks

Since it's only the iMac that's having the issue connecting using WPA, we don't need to troubleshoot the router or the other computers.
I suggest trying the following on the iMac before attempting to reload the previous version of the OS.
If you use "Preferred Networks," instead of "Automatic" for your "By default, join" setting Location, try the following:
System Preferences > Network > Show > AirPort > AirPort tab
- Delete all preferred networks with encryption
- Add them again after manually connecting
(Note: It will be faster if you turn on "Automatically add new networks to preferred networks list" under "Options" of the AirPort network connection.)
If this doesn't work, something might have gone wrong with the update to 10.4.8. I would suggest that you follow the Apple Tech's recommendation and reinstall the previous OS using the installation disk that came with your iMac.

Airport Extreme Cannot see Live Internet Connection from Cable Modem

Hi,
When I run a cable directly from my cable modem to my MacBook everything works fine. In fact, that is how I am connected to the Internet right now.
However, when I run the same cable into my Airport Extreme (AE) and then connect my MacBook to the AE (wired or wireless), the AE reports a problem connecting to the Internet. This is a new situation as everything has been working fine for months. I have changed nothing in this set-up for it to stop working.
I can only assume the at the AE is broken: the Internet connection is live, it was working fine for months and then stopped working. Is there anything I should try before I throw the AE in the garbage?
Thanks in advance.

Welcome to the discussions!
It appears as if you may not be aware that cable modems must be completely reset whenever the device that they are connected to changes. The reason for this is that the cable modem "remembers" the device that it has been connected to. In your case, it's "remembering" your computer and looking for it when you plug it in to the AirPort Extreme.
You need to make your modem "forget" your computer. Here's how:
o Push the reset button on the modem if there is one on your modem
o Power the modem down immediately after you push the reset button
o Pull the battery in the modem if it's easily accessible
o Leave the modem powered down at least 20-30 minutes (Some ISPs take longer)
Power down the rest of your network as well.
After the power down period, start the modem first and let it run 3-4 minutes by itself
Then start the Airport Extreme (you may need to "hard reset" the device again to start over on the configuration) and let it run a few moments
Then start your computers one at a time
Please post back on your progress. Remember, if you need to connect your computer directly to the modem again, you must reset the modem again because it will "remember" the AirPort Extreme if you have reset it correctly.

My airport extreme cannot connect to the internet because it says it has no DNS servers. How can I fix this?

I just moved and am setting up a new apartment. Verizon put in internet service yesterday. I got a network going on my airport extreme but it could not connect to the internet because it says it has no DNS servers. help! What do I do now?

Ensure that the ethernet is connected to the WAN port (with the dotted circle).
You may have to reset and reconfigure your Airport Extreme.

HT4259 My old Airport Extreme cannot connect to the new Airport Extreme (Base) after I upgraded to the 7.7.1. firmware.

The old extreme was working as part of the extended network when the New Extreme Base it had the 7.7. version, now amber just blinks away.
I tried hooking up an Airport Express and have the same problem.
Any pointers?

Ensure that the ethernet is connected to the WAN port (with the dotted circle).

After using hotel wifi,cannot connect to internet at home network

after using wifi in the hotels this week, i cannot connect to the internet via my home network. I'm connected to the wifi but, can't connect to the internet.

I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
If the above steps do not solve the problem, start over with step 1 above, but then perform the next steps between steps 1 & 2. above.
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref:Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Continue with step 2 in the first set of steps.
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

AirPort Extreme Not Connected to Internet

I have been trying all day to connect a new AirPort Extreme base station. The base station appears to be configured correctly, in that the green indicator light burns solid. But I can't connect to the Comcast Internet: I get an error message that the Ethernet cable is unplugged (it isn't). I've powered down, reset, and restarted the cable modem; and have disconnected and reconnected the power supply to the base station numerous times, but still no Internet. When I reattach the Ethernet cable directly to the Mac everything is fine. I can't tell whether or not the base station is pulling the IP address, etc., from Comcast. Anyway, I'm getting nowhere with this, and would greatly appreciate input from this discussion group. Thanks very much.

Hello driverdude. Welcome to the Apple Discussions!
Although I know you tried multiple resets, please try the following to see if this will get you Internet connectivity with your Comcast modem ...
Try the following, in order, checking for Internet access after each step, or until resolved:
1. If the modem has a reset switch, use it to reset the modem. Wait at least 5-10 minutes for the modem to initialize.
2. Remove power from the modem. If it has a backup battery, remove this as well. Wait 5-10 minutes. Replace the battery, and add power back to the modem.
3. Perform a complete power recycle of your network components as follows:
Modem/Router Power Recycling - Quick
o Power-off the modem, AEBSn, & computer(s); Wait at least 5 minutes.
o Power-on the modem; Wait at least 5 minutes.
o Power-on the AEBSn; Wait at least 5 minutes.
o Power-on the computer(s)
If this fails to get the modem to "recognize" the Internet router, then try the "Full" version.
Modem/Router Power ReCycling - Full
o Power-off the modem, AEBSn, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
o Power-on the modem; Wait at least 15 minutes.
o Power-on the AEBSn; Wait at least 5 minutes.
o Power-on the computer(s)
4. Contact your ISP to have them perform a "modem reset."

Airport Extreme not connecting to Internet

Here's my setup:
imac with Airport Extreme in home office
Airport Express hooked up to home ethernet network in family room to stream itunes (or connect laptop at other end of house)
Just got home and tried connecting my work powerbook to the Airport Extreme network, and suddenly it does not work. Basically times out after trying to connect to internet, even though i get full bars signal-wise, and network diagnostic says i should be connected. I can connect to the Airport Express network in the family room just fine. And my internet connection is working fine over the ethernet network.
Has my Airport Extreme bitten the dust? It's showing full bars, but my Canon i960 stopped printing from it the other day. I thought that was just a problem with the printer, but maybe the problem is my base station?
ps running all the lastest software...
Any suggestions? (Tried restarting cable modem, Airport Extreme, computer, etc. No go.
Thanks for any help.

Hmmm... That's odd that you can't administer the Airport Base Station
from the portable computer (the one you'd later use wirelessly) and
essentially check the thing out thoroughly; see if the firmware and
other things are up to par and the settings are chosen properly.
You'd use the ethernet cable in either case, to access the Base from
the portable or the tower; when you are doing an occasional test and
reset of the Base station. Sometimes, details make a difference.
Another factor may be in how you have the Base station set up to
share internet among computers; the ethernet-only G4 that sees
the through-ported IP dataflow should also be able to administer
the base station. But it may require the Portable, hardwired, to
check the settings and get it to work. I had a similar issue once
with my primary AEBS and had been administering it via a non-
wi-fi B&W G3 tower on ethernet cable; the other computers were
all wi-fi. That worked out great. Currently, I alternately run the iMac
G4 via wireless, and sometimes by wire. I have both set up & ready
and only need to go into the control panel/system preferences; to
make a change. Sometimes the wireless telephone (2.4GHz) is too
close and kills the wireless to my desktop Mac; so I change to wire.
What kinds of addresses are you seeing in your set-up for IP
to each computer? Unless you do actual file-sharing between
them, you can set that up so each computer has a full ISP
address; not those 10.0... or 193.00. or other networking ones.
Sharing a printer is another matter, if you run your AEBS as
though it were a wireless router only, it would be trial & error;
if set up to be wireless printing you'd probably need to get a
wireless USB module to see if that'd work for the G4.
The deal you are talking about, above, is how the device
works. Your G4 tower sees the internet via the through-port
in the AEBS router; it is a wired & wireless router, plus it
can give you wireless printing because it has a USB port.
But only when it is set up correctly. That is easier to do
than it is to write about. When mine fails, I look into it;
and as I suggested in other posts, it will just work later.
PS: In your Portable computer's System Preferences/
Network control pane, see what order it shows the
items or pathways available to connect to the net are
in; if the wireless airport isn't at the top of the list &
is not activated, drag it there. The check-boxes by
each option of course, need to be activated as needed.
When you see a signal, it should be able to find the IP
if the other settings were correct. Sometimes, the basic
defaults work OK right out of the box.
In the portable's System Profiler, you could also see if
there is an assigned IP address given to the computer.
At that point, there should be no reason for it to not work.
Like I said, it is harder to write or talk about it; easier to
see the things and work the strings in the right order!

HT1731 Set up airport extreme, cannot connect express, help?

COnnected a new extreme, tried to connect a new express to upstairs to increase range and add devices, amber light won't go out on express. Cannot locate the device on the network.

Suggest that you unplug the Express and temporarily move it to the same room where the AirPort Extreme is located.
Power up the Express and let it run a full minute or two. Then, push in the reset button on the Express and hold it in for 7-8 seconds, then release.
Allow 40-45 seconds for the Express to restart and display a slow, blinking amber light.
I am assuming that you are using AirPort Utility for the iPad since you mention iOS 5.1 in your post. If not, download and install App Store - AirPort Utility
Tap Settings on the iPad home screen, then tap Wi-Fi
AirPort Express should appear under the heading of Set up an AirPort Base Station
Tap AirPort Express, and AirPort Utility will take a 25-30 seconds or two to examine your network and then declare that the Express will be setup to extend the AirPort Extreme.
Tap Next in the upper right hand corner of the window and allow a minute or two for AirPort Utility to configure the Express and wait for it to restart again with its new settings.
When AirPort Utility tells you that the AirPort Express is now extending the AirPort Extreme, the Express will display a green light.
Now, move the AirPort Express to a location that is about half way between the AirPort Extreme and the general area that needs more wireless coverage, plug it in and allow 40-45 seconds for it to start up and display a green light.
You should be in business.

Airport extreme cannot connect more than one computer

Hi,
I just got a new cable internet connection but have major problems with my airport extreme. I can be online via airport but I can not connect any other devices wirelessly (including other laptops).
The connection works only when 'distribute a range of IP addresses' is selected in airport utility. Choosing 'share a public IP address' results in no internet access whatsoever. I tried soft- and hardresetting the base station with no luck.
Any ideas?

It sounds like your cable modem needs to be reset.
Most cable modems require that you power them off/on whenever you switch the Ethernet connection from one device to another. When the cable modem is powered on, it finds the new device and talks to it.
Some cable modems have a button on the back to do the reset. Some cable modems have an internal battery which must be removed to do the reset. Some cable modems must be off overnight (or at least several hours) so that equipment back at the ISP can be reset.
"Share a public IP address" is the setting that you want to use.

Can't get Airport Extreme to connect to Internet

I have a D-Link 320T ethernet modem. This works fine connected straight into my Mac, but as soon as its connected to the Airport I loose my internet connection. Its seems to be something to do with my setup, but I'm clueless as to what.
My airport seems to be transmitting something, as my Nintendo DS can pick up the Network name I have created, but it gives me this message "connected to access point, but unable to connect to the server", error code 52100.

Hi Bidge,
Welcome to the Apple.com user discussion boards!
Do you have ADSL? Have you setup the Airport Extreme to establish the PPPoE session with your ISP?
To configure this, please refer to this Apple article - http://docs.info.apple.com/article.html?artnum=166636

The airport extreme is connected to internet modem but the connection is glitchy

The connection is being all weird when I couldn't access the internet and that usually remains for about a couple minutes before it starts working again but then the problem comes back every 15 minutes or so. I've tried restoring it to the factory setting and setting everything up again but it still has the same problem. I don't understand what's wrong with it and it must be the airport extreme since when i connect my macbook to the modem with through the ethernet cable it works perfectly. It happens on not only my macbook but also my iphone 5 and imac. This problem is starting to **** me off when the internet dies every few minutes. Anyone know whats wrong with it?

There are lots of us out there with the same query.Apple can't supply the answer it seems Two ipad in our house with same server ,one fineand the other has the same problem that you have.
DId you contact someone at Apple?

Airport extreme cannot connect to isp

i just bought my first imac and tried to set it up with a new airport extreme connected via a netgear DG834G v3 router. the router and the AE are both functioning fine and showing green for go in all the relevant indicators.
the imac found the AE immediately and i tried to configure it many times to allow internet access but no success.
my iSP is eclipse and if i consult the info it tells me the DNS is dynamically assigned and the Eclipse Broadband connection uses PPPoATM or PPPoA. . also on the AE utility i am selecting the single ISP option not the bridge mode and in the radio option the ' compatible with A and B type' as i recall. can anyone tell me what i am missing/doing wrong ? the network diagnostic does not help.
i can connect to my ISP on this PC via old BT voyager USB modem no problem. i was told the netgear modem was a good ethernet router and would work fine with the AE ?? do i need to get a simpler ethernet modem ??
in the absence of any sunday service from either mac support or eclipse support i would appreciate any advice to get connected.

With the Netgear, you effectively have two routers in your network configuration. You will want to configure the Netgear for PPPoA and reconfigure the 802.11n AirPort Extreme Base Station (AEBSn) as a bridge. This will allow the Netgear to continue to provide both NAT & DHCP services for the entire network.

After scrubbing virus, firefox cannot connect to internet in one area only of my computer

scrubbed a virus win32/nuqel.E and win32/Fake Spypro from multiple user areas on my laptop, now in one user area only I am not able to connect to internet on Firefox, able to connect on Opera in that user area and able to connect in all other user areas with Firefox, what could be causing this anomally?

After 4.2 update cannot connect to internet

Having just updated my Airport Express with the latest update 4.2 I now seem unable to connect to the internet. Yet when I the Ethernet cable directly into my powerbook, no problems. I've run the assistant countless times, Ethernet cable connected, unconnected, completed a hard reset and re-started everything. When I check the Airport Admin Utilty, all the information for my ISP has been detected by the unit and is visable and the second Express unit with printer and speakers seems unaffected. Is there a glitch in the update???

Cheers Paul, for the advice.
I tried but without any luck. Finally I decided to take the advice of NigelReves1 (Topic:airport 4.2 update...no Internet (negotiating PPPoE) Message 7.1.1.1.1.1.1.1.1.1.1.1.1.1.1.1
Downloaded "Binary File" (see link) to desk top and uploaded using the Airport Admin Utility. This puts Airport back to it's 'box like' state. Did a hard reset on both units, run the Assistant and I am delighted to say...It's all systems go!!! So a big Thanks to Nigel!!!
http://www.apple.com/support/downloads/airportexpressfirmware60.html
Anyone trying this, don't be tempted to click OK when you see the prompt 'There is a newer version of software available 6.2'! Otherwise you'll be back where you started!!!
