Networks seen by airport, but can not connect to internet

Hello,
This is for a powerbook G4 running 10.5.8 that previously connected to our time capsule without issues. Recently, it stopped connecting to the internet although our two macbooks, phones, etc. have no problem.
It can see our network and also an open network and will "connect" with full signal strength but will not connect ot the internet. When running diagnostics it will come up with 'network change detected' and then will go through turn off modem and router and will then continue in a loop with turning off modem or router and not let me past the "network settings (yellow tab in front of network settings)" portion of network diagnostics. I've tried setting up a network and this did not work. I have also tried connecting to the time capsule which was not recognized either. I like the powerbook for traveling and since the ethernet source was fried years ago, it is pretty much useless without the airport functioning.
Your help would be greatly appreciated.

Once I had a very similar problem and took it to the Apple Store. I'm not entirely certain what they did, but I believe it was to remove some corrupted .plists. Maybe someone here would know which ones would be the relevant ones to look at.
In the meantime, you might consider one of these as a workaround:

It's not the most elegant solution, but I have a couple of these and they seem to be very reliable, and cheap enough at the sale price.
Good luck!

  • My laptop compaq presario will not connect to the Internet anymore after buying airport extreme. Why? It detects the network, accepts my password, but will not connect to Internet.

    My laptop compaq presario will not connect to the Internet anymore after buying airport extreme. Why? It detects the network, accepts my password, but will not connect to Internet. I tried to repair connection, tried to reboot modem several times, I even updated my computer. Nothing. All it says is that it does not detect modem. Why?

    Welcome to the support community group.
    First, are you sure that your AirPort Extreme has been configured correctly and is properly connected to your modem?
    Begin by telling us how you have things connected and if the Airport Extreme is replacing a previously owned router or is this an entirely new installation?
    First be sure that your modem is working and properly connects you to the internet using an ethernet cable directly connected to your laptop.  Once you're sure that's working, reset the AirPort to factory defaults by disconnecting it from power and pressing and holding in the small reset button on the back  for 15 - 20 seconds while you reconnect it to power.  Then turn everything off for 5 minutes. Connect the Airport to your modem with and ethernet cable to the Airport WAN port on the back (check the user guide to make sure you connect the cable to the correct port) then connect a second ethernet cable between the laptop and one of the LAN ports on the AirPort Extreme.
    Then power up the modem first, wait 5 minutes and then power up the Airport, wait 5 minutes and finally power up your laptop.
    Then run the airport configuration utility from your laptop.  Since you're not using an Apple computer, be sure that all of your firewall, and virus blocking and checking software is disabled before you run the airport configuration utility.  Once you run the utility, it should detect your AirPort and allow you to use the configuration wizard to set things up.
    Check back if you're still having problems.

  • Airport reads full signal, but can not connect to internet

    Hi everyone,
    I have a new powerbook that I'm trying to connect to a home network which is set up with a cable modem and a wireless linksys router. The airport reads that it has full signal from the "linksys" wireless network, however I can not get on the internet through the signal. When I connect the computer directly through the the ethernet port, it works fine. I've taken the computer to another location with the same cable modem and wireless linksys router setup, and it worked fine through the wireless. I've actually had this problem quite a few times with various wireless networks (it connects directly, but not through the full signal that reads on the airport), and I was wondering if there are some setting that need to be changed or checked for certain wireless networks. Any help would be great. Thanks,
    Sofi

    I'm sorry I think this makes thing harder, but I have no idea. It's actually a friend's network so I can't check at the moment. I know there is no password to the network and that they have two pcs running fine wirelessly. Is there a way I can check these settings and see what's going on?

  • I have a signal but can not connect to internet.

    Ok, I have an Ibook clamshell and an airport Graphite. The Ibook picks up a signal but when I go to Safari or Internet Explorer I get a message saying the server can not be found. Help, please?

    In the opening screen of AirPort Admin Utility, check the firmware version of your Graphite base station. It should show up as "Description: Base Station Vx" where x is the firmware version. If it is earlier than 3.84, download updated firmware from this page and install it.
    I found the user guide for your modem on Arris's Web site. It prompts me to suggest the following additional things:
    1. Although the user guide says to use a cross-over Ethernet cable for connection to a hub or home router (as opposed to the supplied cable, presumably a straight-through Ethernet cable, for direct connection to a computer), I believe that the Graphite acts like a computer in this regard instead of like a router. In other words, the Graphite connects to a modem, hub or router using a straight-through cable, but the Graphite would need a cross-over cable to connect to a computer. Try using a straight-through cable, if you haven't already.
    2. Try pushing the Reset button on the back of the modem. Use a pointed, non-metallic object to press the button. I recommend doing this while the Graphite and both computers are powered off, then start up the Graphite first, before the computers.
    3. This type of modem evidently does not itself serve as a router. It has connections for two computers (one via USB, one via Ethernet), but your ability to get two Internet connections through it depends on whether your Internet service provider is willing to supply two IP addresses. (If you try resetting the modem with the pc off, as in paragraph 2 above, and the Graphite acquires a working IP address, enabling the iBook to access the Internet, but the pc then can't, that would indicate that you can receive only one connection at a time.) I suspect that this is, in fact, your problem, unless your cable provider has said that you could connect two computers to the Internet with this modem.
    It would be possible to share a single Internet connection, if the pc has either wireless or Ethernet capability. If it has wireless, you could simply disconnect the pc's USB connection to the modem and have it join the Graphite's wireless network. If it has Ethernet, you might be able to connect it to the modem's Ethernet port along with the Graphite, using an Ethernet hub, but this is difficult and uncertain, as well as less secure. If the pc can handle Ethernet, you'd be better off getting a newer and better wireless base station that has 2 or more Ethernet ports, or, alternatively, a router to be inserted between the modem and both the pc and the Graphite. In any case, a base station that can use WPA or WPA2 wireless encryption would be a great improvement, as the quite insecure WEP protocol is the best the Graphite can handle.

  • NEED HELP, WIRELESS CONNECTED BUT CAN NOT CONNECT TO INTERNET

    SOMEWHAT COMPUTER CHALLENGEDMY LINKSYS SAYS IT IS CONNECTED WITH GOOD CONNECTION, BUT I CAN NOT GET MY WIRELESS COMPUTER TO CONNECT TO INTERNET, BY HARDWIRED COMPUTER CONNECTS FINE. ANY SUGGESTIONS ON WERE I NEED TO START?

    If you want some input from Linksys you have to contact Linksys support. This is a community forum...
    Check the following please:
    1. The computer wired to the router has internet access.
    2. On the computer wired open http://192.168.1.1/ in your browser. The username remains empty the default password is "admin". You may have changed the password during initial setup.
    3. Click on Wireless. Take a note of the Wireless Network Mode (mixed, b only, g only), the Wireless Network Name, Channel, and whether SSID broadcasts are enabled or not. If you still have the default network name "linksys", please change it to something unique and save the settings for this page.
    4. Next, click on Wireless Security and note the settings in this tab. It will be easier for troubleshooting if you post the current wireless settings noted.
    5. Now use the wireless computer (if it was the one wired to the router before, unplug it) and let it search for wireless networks. It should find a wireless network with the "Wireless Network Name" from 3. Try to connect to this network. If it asks for a passphrase or key, you have to enter the passphrase from 4. for WPA/WPA2. If you have WEP encryption in 4. you have to enter "Key 1" not the passphrase!
    6. If the connection fails please posts the exact error message you see.
    7. If the connection succeeds, try to open a URL in the internet, e.g. http://www.google.com/
    8. If it does not work open a command prompt window: Start - Run... - "cmd". Enter "ipconfig /all". Copy the output of this command into your next post.

  • I'm from the USA but am on vacation in Brazil; I have a great WiFi connection but can not connect to the iTunes Store. Is this because I am out of the Country?

    I'm from the USA but am on vacation in Brazil; I have a great WiFi connection but can not connect to the iTunes Store. Is this because I am out of the Country?

    Thank you very much for your insight; I guess I had assummed that iPads/iPhones/iPods were here in Brazil and further assumed that the iTunes store would also be available.

  • MY APPLE TV SHOWS THAT iT IS CONNECTED TO MY WIFI, BUT CAN NOT ACCESS THE INTERNET

    my apple tv found my wifi, but can not access the internet??

    I have been on the phone with Apple, done all of the trouble shooting they have recomended. When I attempt to connect it to the internet I get a message reading "your apple tv is connected to your wi-fi but cannot connect to the internet. I have plugged the modem right into the apple tv and it still won't work. This is the second device I've used. (apple gave me a new one after the first didn't work). I just thought there might be someone out there who had the same issue and knows how to resolve it.

  • Airport status at 3 bars but can't connect to internet

    My 17" Powerbook is the only one of five Macs in the building that isn't able to connect to the internet with our Airport Extreme base station. The airport status icon shows 3 "bars" but will not connect. When we put the Powerbook within 15 - 20 feet of the base station, it works fine, but this is not practical.
    If it matters, the other computers are a G4 MDD, an eMac, a 14"iBook and a G4 iMac "flower", all using a mix of older Airport cards and new Extreme cards. I have checked the Interference Robustness setting and it doesn't have any effect.

    "When we put the Powerbook within 15 - 20 feet of the base station, it works fine"
    So if I have this correct, when the powerbook is close it behaves normally, when it is moved away it still sees 3 bars, but will not connect. but other compouters have no problem.
    it sounded like interference at first, but other computers ought to be similar on that point.
    Can you see the other computers on the network when you can't get to the internet?
    can you see the base station? (airport admin utility)
    any other networks in the area?
    handheld phones / microwaves nearby etc?
    airport card seated properly in the powerbook?
    If you restart does the connection return temporarily?
    any encryption running? if so, turn it off and see if the connection returns after restart.

  • Can connect to LAN wirelessly but can not connect to the internet.

    The problem:
    I can connect to the wireless router and modem router wireless and can browse the router setting web pages etc without issue. However i can not browse the internet, send or receive mail etc.
    The setup:
    A Belkin/iinet modem connects to the internet (ip 10.1.1.1), a DLink 565 then broadcasts the signal wirelessly (ip 10.1.1.100).
    What i have tried:
    Trusty old powercycle
    I know the internet is working via the wifi as my ipod touch has full internet functionality through my wifi.
    I have tried using ip address instead of urls to browse the web to no luck.
    I have tried deleting Libary\Preferences\SystemConfiguration\preferences.plist
    I have tried reseting the DHCP lease.
    The only other thing i know works (eventually) is if i constantly change locations back and forth and turn airport on and off repeatedly, eventually i will get on the wifi but that can take upwards of an hour.
    The macbook also works fine via ethernet connected to the wireless router.

    Check these details:
    1. Right click your wireless connection
    2. Select STATUS
    3. Select the SUPPORT tab
    4. Select the DETAILS button
    You should see a page with all sorts of network details.
    Make sure that you see the following:
    1. You have an assigned IP address from your router
    2. You have a default gateway address -- typically the IP address of your router.
    3. A primary and alternate DNS server address (the router gets
    these from your ISP and passes them along during DHCP connect
    processing.)
    I found that step #3 did not happen reliably. Your mileage may vary. I set DNS server values into my router, based on what I got from my ISP, so that the connect-time data handoff was not required. A large part of my troubles went away.

  • Green light on Airport Extreme but will not connect to internet

    I have tried restarting computer and Airport Extreme but it will not connect to internet.  Unit has been working great up until now.  I have made no changes in system.
    This Airport/time machine is 2009 version.

    The Cisco DPC 3010 is a cable modem, so you will need to let the modem completely reset before you connect it to the AirPort Extreme.
    It may be necessary to perform a Factory Default Reset on the AirPort Extreme and reconfigure it, but we will try a shortcut first to see if that can be avoided.
    Power off the entire network.....all devices....modem, AirPort, computers, mobile devices, etc in any order that you want.
    Be sure to disconnect the power cable on the modem, either on the back of the device or pull the power cord from the wall AC jack
    Leave everything powered off for at least 30 minutes.  Longer is better, as it sometimes takes the equipment back at the ISP longer to completely reset and issue a new fresh IP address to the modem.
    After the wait period, power up the modem first, and let it run for at least 5 minutes by itself. If your modem documentation states that the modem should be powered up for 15 minutes, then go with 15.
    Power up the AirPort Extreme next, and let it run a few minutes
    Then power up other devices one at a time about a minute apart
    When the entire network is back up, check the network.
    It this does not work, you will have to start over again as above, except this time you will need to perform a Factory Default Reset on the AirPort Extreme.
    To do that, power off the AirPort Exterme for a few minutes
    Hold in the reset button on the back of the Extreme.....and keep holding it in for an additional 9-10 seconds while you simultaneously plug the power back into the Extreme
    Release the reset button after the hold period, and allow a full minute for the Extreme to restart to a slow, blinking amber light
    Power off the AirPort now, and start it back up in the proper sequence
    If things still don't work, then you likely have a defective AirPort Extreme that will need to be replaced.

  • Computer is connected to network but can't connect to internet (Safari and Chrome), e-mail, App Store, ect.

    My Macbook is connected to Wi-fi (four bars) but can't connect to the internet or any other services that requires internet. Other devices in my house have easily connected to the internet but every time I open Chrome it says: "This webpage is not available". What do I do?

    Restart your internet modem and router and your Mac then try Safari etc.
    If that doesn't help, try this DNS server ..
    Open System Preferences > Network > Advanced > DNS
    Click + and type:
    208.67.222.222
    Click + again and do the same.
    208.67.220.220
    Click OK.
    Try a browser.
    if that doesn't help, check the firewall.  System Preferences > Security & Privacy > Firewall > Firewall Options

  • HT1752 iMac flat panel 2003 shows airport but does not connect

    Hi,iMac flat panel 2003 shows airport but does not connect

    No problems.
    Let's double-check your iMac's Internet Sharing configuration:
    To setup for Internet Sharing (Wired to Wireless):
    Setup the Network
    Cable Modem > (Ethernet cable) > \[Ethernet port] iMac > (wireless) > MacBook
    Enable Software Firewall (iMac)
    System Preferences > Security > Firewall
    o Block all incoming connections (enabled)
    Enable Internet Sharing (iMac)
    System Preferences > Sharing
    o Select "Internet Sharing" from the options in the left column
    o Share your connection from: Built-in Ethernet
    o To computers using: AirPort (checked) (Note: Uncheck all other entries in the list.)
    AirPort Options... (iMac)
    o Network Name: <anything you want>
    o Channel: Automatic
    o Enable encryption <do NOT enable at this time>
    o Click OK
    o Select "Internet Sharing" again
    o Click "Start" to start Internet Sharing
    o Click Start
    Please verify these settings, and try accessing the Internet from the MacBook again. For this exercise, I suggest co-locating the MacBook with the iMac.
