Airport dont connect to Internet anymore

Airport cannot connect via PPoE to Internet... out of the blue. Connection via Ethernet works fine. I think DHCP dont work.
Airport Base works still fine with Laptop and Printer, but cannot route to host.
Have no idear to fix it. Tried all so far:
- reset Airport
- new Network
- reset DSL Modem
Happened a day after upgrade from DSL 2000 to 6000 and update Quicktime 7.1.1.
Anybody has an idear to solve my problem?

Have you read the thread "Loss of signal after restart following QT upgrade".
Bunyip (the OP) indicated the problem was solved by:
...download and install the latest Airport upgrade (I used AirPortSW42.dmg b/c I'm on MacOS 10.3.9). Then do HARD RESET on your base station or Airport Express and run Airport Setup Assistant to set up your base station as new.
The same solutions seems to have worked for cekulesh in the thread "Cannot connect to AirPort Extreme; after mac os security update?"

Can't connect to internet anymore

Right now I can't connect to the internet anymore through AirPort Express. I'm not sure what the problem could be. I unplugged it from my cable modem yesterday (it still worked minutes before disconnecting). Then, I tried connecting it somewhere else (unsuccessfully by the way). Now, I've tried to recreate my network but it isn't working. I even got it to give me a green solid light telling me that I am connected, yet I can't access the internet wirelessly. However, right now I'm connected with that modem through ethernet. My modem is a surfboard model SB5101U, using airport express.

Hello julios. Welcome to the Apple Discussions!
It's always a good idea to perform a complete power recycle whenever you change network components.
I suggest trying the following:
o Power-down the modem, AirPort Express Base Station (AX), and computer(s); wait at least 10-15 minutes.
o Power-up the modem; wait at least 10-15 minutes.
o Power-up (plug into power) the AX; wait at least 5-10 minutes.
o Power-up the computer(s).
Computers connected by wireless to the AX should now be able to gain access to the Internet. Please post back your results.

Airport Extreme Connected to Internet, Yet No Longer to Powerbook G4

Airport was connected over a cable modem to the internet just fine until last night.
It stopped working--no browser or email.
I can still connect fine directly from the cable modem though.
Internet Connect seems to think I have a strong connection, but my applications (browser, emails) disagree.
I've been accross the internet and back trying to solve this.
I've tried:
a) Apple>System Preferences>Network shows:
"Airport is connected to the network <<my network name>>. You are connected to the internet via AirPort"
b) Apple>System Preferences>Assist me>Assistant
(or Applications>Utilities>Airport Setup Assistant) shows:
"Congratulations! Your Airport Extreme is configured to connect to the Internet and share a USB printer. If you use a cable modem to connect to the Internet, you may need to turn the modem off, wait a few seconds, and then turn it back on."
Internet Connect then, still, shows a strong signal level and status reads: "Connected to <<my network name>>. Connected to the internet via Ethernet."
c) Apple>System Preferences>Assist me>Diagnostics:
Airport works
Airport Settings = failed
It then wants me to reboot the device (i.e., I think, the modem or whatever else isn't sending a singnal to the computer).
I tried this but again, the modem works fine .... it seems to be somewhere between the PowerBook and Airport Extreme that is the problem.
d) I've tried with no success downgrading from Airport Extreme Firmware V5.6 to V5.5.1
e) With no success I've reinstalled from CD the Airport Extreme software V4.2
f) With no success I've selected "Enable interference robustness" thinking perhaps another network in the building was interfering (airport seems to recognize another airport but iStumbler doesn't seem to).
g) I've messed with Apple>System Preferences>Network>Configure so much now that if there was anything that isn't broken, it probably is now.
I've taken a crash course in AirPort over the last 24 hours (and failed) and have soft (5 seconds) and hard booted (30 seconds?) this thing so many time .... I'm ready to, you know, boot it out the door next (it has a nice aerodynamic shape I've come to really appreciate in the last several hours).
I know there is something I'm doing wrong, overlooked, or haven't tried.
Any thoughts????
Thanks in advance,

Jayson,
It sounds like your airport needs to be changed to no longer distribute IP addresses the way it is currently set to do. Go to the airport setup, make note of settings as you go (shift + command + 4, select area with "crosshair" cursor and let go to make a pdf of the screen, selected area, print the pdf in PREVIEW if you want to save yourself the time writing them down!), and MAKE SURE YOU ONLY CHANGE WHAT YOU UNDERSTAND and are sure of. Sorry for yellin'!
In the airport settings (sorry, I'm retrieving from my organic grey/white matter memory here), I believe there is a place in the internet tab for changing the APX to no longer distribute IP addresses, or to share single IP's, etc. If you wish, try to see if toggling off the distribution, rebooting (not resetting) devices, and starting up the computer allows a "tunnel" through the modem.
Many cable/DSL modems are firmware-set to ALSO distribute IP addresses, so the two devices (modem and airport) are constantly sending packets back-and-forth, handshaking endlessly and the most recently "shaken hand" is the device distributing addresses.
The problem arises here (or, at least this is one case I am describing in which your symptoms match up closely) since your computer sees the packets, the web traffic and "open door," etc., but it is somewhat like thinking a window is a door. You can see out of it, verify the "door" by looking outside, but the lock is on the OUTSIDE (the modem), locking you in, with your airport sitting idly and thinking that you can get out since it is essentially letting you have a distributed IP address...it's all rather like the mom from "Carrie" or something...you and your dirty pillows. Stay inside the closet for now-- yeah, right.
If shutting of distribution in your airport still allows the computer to connect as wired to the LAN port and your modem still plugged into the airport's WAN port (after saving airport settings and rebooting all devices, computer LAST, airport a few minutes after the modem), you are even more likely to be in this aformentioned battle of the handshaking devices.
If so, find out from manuals/manufacterer's online notes/good state-side non-Apple tech help (and other fictional situations) if the cable modem can be set to not act like a router, and more like a modem by just giving one DHCP address, or static address if you must, and not conflicting with a router. Don't say airport unless you must-- so many tech-help places quote the crapola cop-out that Apple isn't compatible or something. Most of the time, cable modems only require the fairly universal web packet compatibility, and the mac/airport does the rest. Very few modems, especially from a large broadband provider, will prevent you from using an airport or a mac. The few I have seen were firmware issues with older, rather ready-to-be-shot DSL modems that should have been doorstops or clay pigeon surrogates a long time ago.
If you can play around (with guidance) and reset the modem to simply get an IP, send it to the router (that is, the airport), and then let the airport do the distribution, all you have to do is switch the airport back to distributing a range of addresses-- I like the 10.0.1.x selection, but I find the last of three choices (something like 169.x.x.x) to occassionaly be the magic x-factor bullet from Narnia that makes the bells ring and your airport finally wired AND wireless.
Before you heed any "advice" I may be stating, do some googling regarding the topics I mentioned, since NOBODY is all-knowing or perfect in ANYTHING, and I don't want your problems to be worse. Exhaust all other sources of information that you may have, but the above prattling was from my troubleshooting an endless stream of constant problems with a similar setup, and it may help you. Reply if you wish and I'll add more if you want.
Sorry if I'm writing like a monkey *(&%% a football on an icy pond. I'm juggling a few upgrade jobs on my workbench, and listening to the new INXS album from itunes, so I'm a little geared up. BEST OF LUCK! Happy holidays, whatever they may be for you.

Airport loses connection to Internet under heavy load

Often, all the computers in my house will lose their Internet connection. However the network stays up just fine. There are both wired and wireless computers. A Netgear 16-port switch handles all the wired machines. The only solution is to pull the power cord from the AEBS and plug it back in. 30 seconds later, everyone's Internet is back up. The AEBS gets its Internet connection via PPoE to our DSL line.
From recent experimentation, I've discovered that this happens a LOT more frequently (at worst, every few minutes) when there is a lot of Internet traffic - many short connections, like when I run web scraping bots. If we go on vacation for 2 weeks, the connection stays up fine.
I know this problem has been discussed before but I've never seen a solution. All Macs and AEBS are on the latest software. Any suggestions?
- Desperate for AEBS love

I'm experiencing problems with airport connections recently, too. I did a lot of analysing since then.
My configuration is based on a linux-driven NAS connected to two wireless acesspoints (1x SMC Barricade 2804WBR, 1x Fritzfon with recent firmwareupgrades). Two PowerBooks are connected with cable, two use their inbuild aiport cards.
Volumes are mounted from teh NAS via NFS.
Everything worked flawlessly for serveral month until, I assume, to the 10.4.8/10.3.9 update. I'm afraid the net isn't this much loaded that the connection losses were showing up immediately.
But then there was the need to rebuild the iTunes biliothek on the MacBook Pro which uses WLAN (connected to the SMC). For some time the connection worked but then the connection to the server (NAS using NFS) was lost. I tried it with cable an without (10.3.9 and 10.4.8). The same problem occured.
I tried to transfer different kind of files and folders an identified some files which seemed to cause the server losses. Always at the exact same point. But I had to learn that theses points differ whether I connect via the SMC or the Fritzfon. I have to say that the connection via the Fritzfon are somewhat more stable.
Fact is, that if the problem occures the whole network stalls, not only the connection between WLAN accesspoint and the client computer but the connection between cable-connected ones, too.
It's even possible that the server or the SMC becomes unresponsible via telnet so I have to restart it by pressing the reset-button.
I think I'll roll the MacBook Pro back to 10.4.7 and do some extensive testing with only this one active in the net.

Airport Extreme Connected to Internet but Macbook Pro will not

I'm living in an apartment and using an Airport Extreme to supply wireless connection. The internet is paid for by the apartment complex and I have no access to the modem. Up until yesterday the internet worked fine for all devices. I did several factory resets on the Airport Extreme and now have confirmed internet access with my PS3 and smartphone connected to the wireless network. However, my macbook pro will connect to the wireless network but will not go beyond that to the web. I have renewed DHCP leases, reset network configurations and deleted plists to refresh everything but it still does not work. I have noted that when connected to the network, I have an IP address that begins with 192.168.x.x and the macbook states the router address begins the same way. The Airport Extreme displays an IP address of 172.xxx.x.x
I can manually input the routers IP address into my laptops network configuration and create an IP similar and connect to the internet through the laptop but if I want to connect to other networks I have reset that information. It simply won't work automatically. The airport extreme is setup in bridge mode. That is the only setup which would offer stable networking without any dropping or the device disappearing from the airport utility.
I'm currently out of my apartment and will call my ISP later today, but this problem has affected my roommates macbook's as well. My last attempt to connect directly into the wall ethernet jack yielded the same results without any internet connection.

Try this:
Put the Airport Extreme in Bridge Mode and plug the apartment ethernet cable into a normal ethernet port on the back of the Airport Extreme instead of the normal "Internet" ethernet port.

Applications Dont Connect To Internet

I don't remember what I did, but multiple programs (ie: software update, itunes, twitterific, adium) wont even try to connect to the internet. I can't figure out to see what the problem is. Other programs work fine (ie: firefox, mail, WoW) but these others simply wont connect anymore. I ran onyx, but that didnt fix anything. If anyone has some suggestions or advice please feel free!

Welcome to Apple Discussions:
Check your console logs for indications of what is happening or not happening.
Run console.app and search the results for information.
You can also create a new user and see if the problems occur with that account.

Airport Shows Connected to Internet, but won't actually connect...

My wife is having trouble connecting to the internet on her Macbook Pro and I've tried everything I can think of to get it corrected, but nothing has worked yet. The airport wireless signal shows that she is connected to the interest and has full bars, but she is not able to access the internet or check her email (through mac mail). She is right now out of state, but has not been able to access the internet in the two places where she is (the interest is working because everyone else around her is accessing it fine).
I've done the following to try and correct this so far, with no luck:
- turned airport off, then back on after 10 seconds
- fully shutdown the computer, then restarting
- renewed DHCP Lease
- checked proxies to make sure nothing is selected
Does anyone have any ideas on how to fix this? She has not downloaded or installed any new programs or even used the laptop in the last 48 hours. I've heard of this happening to people before, but the above solutions have not worked to fix this.
Many thanks in advance!

Airport stopped connecting to internet - ethernet cable OK

Last night, my wireless stopped working. When I looked at the network diagnostics, it had everything fine up to and including the ISP, but then it couldn't find the internet from there. I rebooted my modem but to no avail. I then tried just connecting the ethernet cable to my mac and that was fine (once I'd rebooted my modem). However, I still am having problems with the airport. I tried a restore to factory settings but I still can't get anything. Has anyone else had this issue?

I know that you have already tried a number of resets, but I would recommend that you try the following:
Power-down the modem, AirPort base station, and computer(s).
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.
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).
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.

MBA cannot connect to internet anymore

Hi,

Apologies for the above - full question here:
Hi
have been operating a home network successfully with MBA, Time Capsule, Brother printer and 2 iPhones all connected wirelessly. However, yesterday, I had to unplug and move everything to position a new desk in my home office. On restarting, everything apart from my MBA is working perfectly with regards the network/internet.
Initially, in Network Preferences, Airport had a green light and stated ON, but with the message 'AirPort has a self-assigned IP address and may not be able to connect to the internet'. I checked this out on the forum questions, tried a few suggested ideas and now Airport has a red light and states 'AirPort does not have an IP address and cannot connect to the Internet'.
Everything else looks fine, my printer is picking up the wireless network the Time Capsule is showing a green connected light on the unit and both iPhones are operating on the network.
The AirPort menu bar status is displaying as connected to the correct secure network but I can't seem to move forward from here to connect to the internet.
The other odd thing I noticed this morning is that in Finder under 'Shared' (where usually I can see the TC etc) it's showing a MacBookAir (almost as if it's detecting itself???)
Any suggestions would be gratefully received - please bear in mind I'm not hugely technically minded so layman's terms would be preferred!
With thanks in advance.

Airport is Connected, But Internet Doesn't Work

Hey guys. I have a 17" PowerBook G4 running Tiger. My problem is with Airport. I can't seem to connect to any network. What's strange is, I have a full signal, Open Internet Connect shows that I am connected. Everything seems ok. I can use ethernet to connect to the internet. I know that it is an issue with the computer because I can't connect to any networks, I've tried about 4 times. I've tried network diagnostics and assistant, nothing works. Any ideas?

if ur connecting to a home modem-router(not someone elses), id suggest turning off any other computers attached to the modem or router network, and then turn off ur powerbook, unplug ur router and unplug ur modem and leave for 2 minutes, then turn modem on-wait 1 minute-turn router on-wait 1 minute-turn powerbook on and try to connect

Airport express connects to internet, but not print server

hello all. i hope someone can help me with this. 2 days ago, my wife was able to print using her ibook/airport expess setup. today, the network diagnostics has this message: "network diagnostics was able to connect to the internet but not to the server EPSON Stylus CX3800.pdldatastream.tcp.local. this could be caused by problems with the server, or an internet problem between this computer and the server." she says this happened when she turned it on. what could be causing this? any and all help welcome. mcrat

You can reset the AirPort Express (AX) following the directions in Resetting an AirPort Base Station or Time Capsule FAQ.
Then you can use AirPort Utility on your computer to configure the AX.

Airport express connects to internet, will play via airplay, but not through itunes.

Hello all-
I just updated to the latest iTunes 12.1.1.4 64 bit and now itunes can no longer send music to my airport express. It is directly connected via an ethernet cable. The wifi portion of the airport express works, I can find it in the airport utility, I can send music via airplay from my iphone...just cannot connect to the device in itunes to play music. I also tried airfoil and it cannot find it either. Thanks for the help

Thank you for responding, Duane, I'll give it a try. I suspect the cordless phone is the culprit. I do wonder though, if it is why my Safari and Mail aren't kicking in even if the Wireless Network is working fine.
If I may repeat that part of the issue: often, when downstairs, I actually can connect to the wireless network, and I see in the network connection window the words "Connected via PPoe", yet Safari will not connect to the internet, claiming "could not find PPoe"; and Mail will not connect to the online server, instead reading "working offline" no matter what I do. At such times it's almost as if Safari and Mail are in a different non-functioning universe than my functioning wireless network. Why won't they go along for the ride?

Airport not connecting to Internet, but I can connect directly

Hi - My Airport Extreme (4th Generation) suddenly popped up and told me it was reporting problems. I cannot remember exactly what the issue was, but I think it was something with the IP address. (sorry, I know that's not helpful.) Since then I have talked with my ISP, found I can directly connect via the ethernet, and wiped the Airport back to factory settings. Any suggestions? I can connect to the Airport, but it doesn't go out to the Internet. Again, it's not the ISP, because I can connect with the Ethernet. Thanks!

A little more info - I remembered the error had to do with Bridge mode, telling me I had to either turn it on or off. And the current issue is that it does not have an IP address??? But I see an IP address on there - it's not pulling it from the modem??? Thanks!

Airport not connecting to Internet

Hi
I have an Airport network using WPA personal encryption. I've set the mac to log onto my network when booted which it does. When I try to access the Internet, it won't connect. When I check 'Internet Connect' it says that i am logged onto the network, but not the Internet. When i also check airport admin, my airport express does not show up in the window, even after rescanning.
I have to turn off the Airport, then turn it back on again, select my network and after about 20 seconds it says, 'Connected to (my network)" " Connected to the Internet via Ethernet".
I have a windows machine sharing my network which has no problems (which pains me to say!).
Any ideas how to solve this.
Thanks

Take a look at my FAQ:
http://www.macmaps.com/WIFI1048.html

Can I use my airport to connect to Internet with my Mac?

So I currently don't have internet on my iMac right now and so I tried connecting an airport express and making the airport join my current wireless network (since I don't think iMacs can join wifi by themselves), and I entered all the information about the wireless network I want to join, but when I reset my airport to these configurations my iMac can no longer connect with my airport so I'd like some assistance, and if it turns out trying to do this is impossible, I would also like to know that too, thanks.

So I currently don't have internet on my iMac right now and so I tried connecting an airport express and making the airport join my current wireless network (since I don't think iMacs can join wifi by themselves)...
There are numerous iMac models; which exact model do you have as most of the later models have built-in wireless capability? To find out, you can use System Profiler by first clicking on the Apple icon in the upper-left corner of the menu bar, and then, selecting the "About this Mac" option.
If your iMac actually does not have wireless and your AirPort Express Base Station (AX) is an 802.11n version, you could configure the AX as a wireless Ethernet bridge. Apple calls this a ProxySTA. In this configuration, you would configure it to join an existing wireless network (like you already did) but enable it to support a wired client. You would then connect the iMac directly to the AX by Ethernet.
