Another airport connecting to internet problem! Please help!

Hi, I'm having a problem connecting to the internet on my iMac G5 running OS 10.5.8.
It initially started happening on and off after I upgraded from 10.4, now it happens all the time.
Airport connects to the network (full 5 bars and I can see the other machines on the network), but can't connect to the internet. When I run Network Diagnostics, I only get as far as Select Airport network, but it keeps scanning forever but doesn't find the network. Meanwhile my iBook G4 and a PowerMac on the same network connect no problem.
I get the Self Assigned IP address message in network preferences.
I have searched the forums for this problem, and found lots of other people having the same problem, but none of the suggested fixes have worked. The only thing I can't do is reboot the modem as it's my landlords network and I don't have access to it.
Things I have tried include:
-turning airport on and off
-deleting the airport preferences plist file from system preferences and rebooting
-deleting airport from network preferences and adding it again
-deleting all locations and creating a new one
-using manual dhcp and putting in an ip address same as the ibook with 1 extra number at the end
-turning of the firewall
-rebooting rebooting rebooting
None of the above works. Can anyone can suggest any thing else? It's driving me crazy! I know there are lots of other posts on this topic but I think I tried all of the fixes suggested without any success.
Thanks

There is a fair chance it's a problem with the DNS settings your ISP uses. Here is what I'd recommend.
1. System preferences
2. Network
3. Click Advanced
4. Click DNS tab
5. Click + sign
6. Add 208.67.222.222
7. Click + sign
8. Add 208.67.220.220
9. Click OK.
10. Exit System Preferences
11. Try out your iMac and report what happened.
Regards,
Roger

    I installed itunes 10.5 in my PC to sync with my ipod touch $G but it's giving me error message that itunes could not connect to itunes store..."make sure network is active and try again." I'm connected to internet though so I don't understand please help!

    Close your iTunes,
    Go to command Prompt -
    (Win 7/Vista) - START/ALL PROGRAMS/ACCESSORIES, right mouse click "Command Prompt", choose "Run as Administrator".
    (Win XP SP2 & above) - START/ALL PROGRAMS/ACCESSORIES/Command Prompt
    In the "Command Prompt" screen, type in
    netsh winsock reset
    Hit "ENTER" key
    Restart your computer.
    If you do get a prompt after restart windows to remap LSP, just click NO.
    Now launch your iTunes and see if it is working now.
    If you are still having these type of problems after trying the winsock reset, refer to this article to identify which software in your system is inserting LSP:

  • Brand new macbook- cant connect to internet. Please help!

    Hi everyone, brand new macbook. i connected the ethernet and its giving me all these problems and will not connect to the internet. I tried to just let it configure automatically but even that doesnt work.
    I have ethernet via time warner cable btw.
    please help!
    thank u!

    Here is how to do a power cycle or what is called a reset.
    Plug in your mac to your modem
    Un plug the power cord to your modem
    Wait 5 seconds, then plug the power cord back in
    Give a minute or so to reboot and re-config its settings
    Try clicking on safari and connecting to the internet
    This should work, if not use the mac internet connect wizard to try and fix the problem.
    If both of those solutions do not work then post back here.

  • All Kinds Of Internet Problems - PLEASE HELP!

    So I've been having all kinds of internet problems in my house. I'm almost positive part of it is router related but I just (somewhat scientifically) proved it's also related to my mini. I used speedtest.net to test both my brand new mac mini and my 2006 macbook pro running Leopard 10.5.1 (fresh install). Here's the specs and speed test results:
    _*2006 Macbook Pro*_
    Intel Core Duo 2.0GHz, 2GB RAM
    OSX 10.5.1
    *Average Results:*
    Download - 4.72 Mb/s
    Upload - 0.84 Mb/s
    Ping - 24-38ms (range)
    _*2009 Mac Mini*_
    Intel Core 2 Duo 2.53GHz, 4GB RAM
    OSX 10.6.2
    Results:
    Download - 0.78Mb/s
    Upload - 0.97Mb/s
    Ping - 15ms
    *AFTER PRAM RESET:*
    DL - 2.85Mb/s
    UL - 0.98 Mb/s
    Ping 22ms
    *these were the BEST results and far above the average I got
    Router:
    Netgear WGR614v9 running latest firmware
    WEP 128bit security B/G combined broadcast
    We were running WPA2 security but when I switched to WEP everyone in the house noticed a speed increase.
    The tests were run within a span of 10 minutes and both computers were about 2 feet away from each other.
    Can someone please explain to me why my nearly 4 year old MBP with an outdated OSX is spanking my brand new mini?

    I apologize ahead of time as I am not sure I can answer your question, but I would like to ask you a question if I could...
    Are you using your mini with Ethernet cable or Wireless. Not that there's a real difference in your case but sometimes if you're running with a Wired Ethernet cable on a unit that also has wireless, it helps to turn off the wireless.
    And on the other hand if you are not running with Ethernet cable on the mini, you might think about trying that.

  • I am Using manual proxy settings but My apps such as Garageband connote connect to internet. Please Help!!

    Hello there,
    I am having a wifi connection with proxy. I am able to browse net through it can access Appstore or iTunes but apps such as Garageband cannot connect to internet. If theres any solution to it then please tell.... I will be really thankful.

    Hi,
    I have the same issue.
    Proxy server in my office does not allow apps like iTunes and Garage Band to connect to the internet.
    I believe the IP ports are different from 80 an 8080 and they are not tunable.

  • Itunes connection and Passcode problem (Please Help!!)

    So, my computer recently was broken beyond repair.. so when I got a new computer and redownloaded itunes i tried to connect my itouch to charge it and i noticed it said "Itunes cannot open ipod in library please imput password on ipod" I never put a password on it... aparently one of my friends did. So I was being a total DA and attempted to guess the password too many times now the ipod's disabled untill i can connect to itunes and itunes wont let me connect untill I get the password, I'm at a total loss please help!

    You need to place the iPod in recovery mode and then connect it to your new computer and restore it via iTunes. Note that you will lose all content on the iPod. You can redownload apps at no additional cost provided you are signed into the same iTunes account that originally purchased the apps.

  • IBook and Comcast Cable modem--can't connect to Internet? Please help

    Hello everyone!
    I have an ancient iBook . Here are the stats:Mac OSX version 10.0.3(told you it was ancient), 193MB, PowerPC G3. I bought it off of eBay about two in half years ago and it didn't come with an Airport card...I only received a laptop, the original box, some cds, and the adapter. I have a Comcast cable modem and I was wondering if anyone could help me figure out how to connect my iBook with the modem. Prior to Comcast, I had Bellsouth and all I had to do was simply unplug one end from my mother's Dell and plug it into my iBook and it instantly connected. However, I can't do it with the Comcast. Can anyone tell me how? Pretty please?
    iBook   Mac OS X (10.0.x)   PowerPC G3, 193MB

    You likely need to contact Comcast to get them to help you set up the iBook for your new cable internet service. They should be able to walk you through it.

  • While using the computer the wi fi dropped out and it can longer find any networks. I have played around with the air port etc , still have no networks and can't connect to internet. Please help

    Hi I am having Wi fi connectivity issues , while using my computer the wi fi dropped out , I can no longer connect and no networks come up. I have tried looking into the air port, trying manually to connect to the desired network with no success , it says the Wi fi is turned on. I am at a loss to why it will no longer connect, please if you have any suggestions,as I tried to ring apple support but my warranty has expired this is my first major issue since I purchased it in 2009.
    Thanks

    My 4s i-phone which is 2 years old cannot find any wi-fi networks not even my home network... I had the same problem two months ago but i turned off the i-phone for 8 hours and then it was okay... Now it happened again.... I tried to restart the modem but whilst my laptop is connected regularly, my phone still cannot find any wi-fi networks... I restart the i-phone, i reset it, i chose reset network settings, reset all settings, i turned it off for a whole day in case it was overloaded, i turned on the airplane mode and turned it off again, i put it into the freezer for 10 minutes within a zipped bag but 3 days now and i still cannot be connected to my home wifi... I went to the technician today and he told me that it means that wi-fi is broken and that i need to change it with a charge of 70 euro but i have to give my phone for 10 working days so as to be fixed... I am so frustrated and i don't know if i want to give 70 euro for wifi since i don't know if it would make the same problems again... 

  • Airport problem; please help

    Hello
    Heres the problem; In my network/internet settings for airport the message is this: AirPort is connected to the network ___________
    AirPort has a self assigned IP address and may not be able to
    connect to the internet.
    HOW DO I FIX this problem? Thank you for your help!
    Jimmy

    I am connected right now using "Built in Ethernet" but when I was using
    9.1 OS, the airport connected with no problem. I was on the net just fine then when I had 9.1 on the same machine, not now. Ever since I Loaded Panther OS X, I have not been able to have a internet connection using AirPort on the newer OS. My AirPort signal to the computer is fine, and on. The message that I am reading in "network" window reads like this:(AirPort is connected to the network (Mynetwork) wireless. AirPort has a self-assigned IP address and may not be able to connect to the internet)
    I am stuck not able to use my AirPort to connect to the internet via AirPort only, just by using "Built-in-Ehternet.
    I thank you all who have and will help with this problem,

    Additional things to try.
    Try this first. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

  • My iphone 5 doesn't sync with itunes on my pc. it says this computer has  previously been synced to another io6 device or iphone? please help what to do?

    My iphone 5 doesn't sync with itunes on my pc. it says this computer has  previously been synced to another io6 device or iphone? please help what to do?

    The error message you're seeing is likely the other way around -- i.e. something like "This iPhone has previously been synced with a different computer".   There's no problem syncing multiple iOS devices to the same computer.
    However, the reverse is not true for the iPhone --  you cannot connect an iPhone to another computer without it being erased, even if you manually manage music and video.  So, it sounds like you've been syncing your iPhone to a different computer?
    Also, 5.1 (not 5.0.1) is the latest iOS.
