Airport card recieves signal but won't connect to internet.

I have a PowerBook G4 with OS X 10.4 (it came with an airport card) and in the next room over I'm using a PC with a D-link (Dl-524) 2.4GHZ router. The problem is that my laptop tells me it's connected to the group, and it says the signal is strong, but when I try to open Safari, Safari tells me I'm, "Not connected to the internet." Therefore, I think the problem lies not with the third party router, which is sending out the signal just fine, but with my laptop, or wireless card. Is there some setting I can change? This problem has existed for months, and I have to reset the router a couple of times a day.
This is what I do EVERY TIME:
*Reset the router - laptop still has the signal, now with the defalt groupname 'dlink'. Signal is still strong, but Safari tells me I'm not connected to the internet.
*Make a new group name for the router and click 'apply' (using the PC in the next room)- suddenly my laptop has internet.
It's bizarre. I don't understsand. Please help me.
PowerBook G4 Mac OS X (10.4) D-link router connected to PC via Netgear router

Hello everyone. I'm wondering if there is any new information to be reported on this thread because I'm having the same problem as adrixray.
I have a MacBookPro that I'm trying to connect to my new Airport Extreme. I upgraded to the Extreme from an old Linksys wireless B router that has been running perfectly fine on my Comcast modem(s) for 3 years. I upgraded so that I could use the Extreme on my AppleTV but so far I've had no luck getting it to work.
I've tried power cycling about a dozen times, had Comcast reset the modem, even talked to Apple tech support for about an hour and a half on the phone-- no luck. Tech support tells me it might be an issue with Comcast but, as I say, I'm able to successfully connect directly to the modem with an ethernet cable and am able to connect wirelessly with my Linksys connected. I've tried to connect with multiple devices and all of them can connect to the wireless network successfully but can't connect to the internet even though the light on the Airport Extreme is green.
I've searched multiple forums and found that many, many people have experienced this same problem and so far I haven't seen any solutions posted. Could it be a defective batch of routers?
adrixray: I would love to hear if you were ever able to resolve your issue.
Many thanks to all for your advice/help.

Airport card sees networks but won't connect.

I'm not entirely sure why.
Wired ethernet works fine, and our G4 Desktop's Airport card works fine.
Mine, however, is being a bit wonky.
I shut the computer down for the night about a week ago.
Brought it back up and got the "There was an error joining AirPort network *our SSID*".
Fine, sometimes it does that. I wait and it usually works in a few minutes.
Not this time.
We rebooted our Linksys WAP and our Cisco router, no good.
Shut the iBook down again, reseated the Airport card, fired it back up and paid close attention to the verbose boot this time.
Nothing abnormal, no errors.
Still no wireless connection.
I've tried connecting to other wireless networks around us, and we even defaulted the WAP back to out of box state (i.e. it was wide open and not passworded), but nothing. Every other wireless device in the house (G4 desktop, Dell laptop, and a Toshiba tablet) works just fine.
The computer can SEE wireless networks, but it can't connect to anything.
There have been no major system updates recently, and the only program I've installed in the past 3 MONTHS has been the World of Warcraft Burning Crusade expansion. Nothing else has changed, which is what's stumping me.
I'm starting to wonder if:
A) I'm overlooking something incredibly simple.
B) My airport extreme card is dying.

firstly, tesserax, a tremendous thank you for your help. unfortunately, i tried each step you suggested, but the problem continues.
step 1: i have tried and failed to connect to several different networks in a handful of locations (home, work, friend's house, local coffee shop, etc.).
step 2: i have disabled my own wireless encryption as well as the wireless encryption at a friends house, however, to do so i had to use their ibook, as my own either didn't list the base station in the AirPort utility (although it did list the base station in the AirPort status pull down), or it asked for a password even though the base station wasn't password protected (maybe this may add some insight into the issue?).
step 3: i have connected the computer directly to the modem using an ethernet cable and was able to go online - perhaps this means the problem is related solely to the card.
step 4: i moved the the com.apple.networkConfig.plist file and and the SystemConfiguration folder to the desktop and restarted. unfortunately, OS did NOT rebuild the files. instead, i had to go through the network diagnostics to rebuild them manually. while the files were replaced, the problem was not solved.
step 5: i reset the PRAM, but the problem still exists.
step 6: i reset the PMU, but the problem still exists.
i then tried various combinations of your suggestions, including moving the files out of the preferences folder and then reseting the PRAM and the PMU, but still nothing.
after having attempted every fix i could think of (and that was before posting to this forum) i did a full erase and install of the OS. since that's usually the cure all to whatever ails the computer, it's my assumption that the issue is a physical (hardware) one. that said, if you have any other suggestions i will be more than happy to give them a shot.
thanks again,
brad

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?

AirPort Extreme Card recognizes networks but won't connect - HELP!

hello forumites,
firstly, if this post is similar to one that has already been well-read and widely responded to, i apologize and ask that you respond with the link to said thread.
my issue pertains to an iBook G4 (circa 2004 i believe) running OS X 10.4.11 with an apple-installed AirPort Extreme card (firmware version 405.1). i have never had any problems with the card previously, but in the last week it has quite suddenly ceased to connect to any wireless network i attempt to log on to (both password protected and non). despite the card's sudden inability to connect, it still is able to recognize all the wireless networks in my location (i know this as the networks are still listed in the AirPort status pull-down menu).
in an effort to fix the issue i have:
restarted the card (turned it off and on)
restarted the computer (many, many times)
used the network diagnostics program
used the network setup assistant program
attempted to connect through the system preferences (network)
attempted to connect through internet connect
did a complete erase and install
still nothing.
anyone had a similar problem? anyone find a way to fix it?
thanking you in advance for your brilliance and time,
brad

Time capsule produces a signal, but won't connect or backup

I have looked at some of the other discussions here; some are similar, but I can't find an answer.
I have a TC, Macbook Pro and an iPhone 4, all between 6-10 months old. My problems started when I turned on all my stuff after being away for 4 weeks over the summer.
My Macbook pro's AirPort recognises the TC - I have a 'full signal' reading at the top of the page. However, when I try and connect to the internet, I'm told it can't connect to the server. If I just keep trying, re-entering addresses (from the scroll-down bar, so always exactly the same), it eventually connects and I have a great connection, which I can use to watch movies/download stuff no problem. Why is it so **** illogical? Why does it connect on the 20th attempt, and not on the first? This happens however long the computer has been on, and regardless of when I last connected to the internet.
The biggest problem is that I have a Vodafone 'Sure Signal' signal booster attached to the TC. Without it, I get no phone signal. The Sure Signal does not recognise the signal from the TC at all. I have done factory resets on both - individually and together, and nothing has changed. I have turned the Sure Signal off, but the TC still doesn't work properly.
My iPhone won't connect either. It too shows a 'full signal', but when I try and connect it says connected/not connected alternately about every 1 second.
The TC is connected to the internet via a cable from my landlord's router, next door. They have perfect signal. They also have a signal booster in their house, which used to interfere with my TC (when it worked). I changed the channel on my TC, and now, when it connects, there is no interference.
Please can someone enlighten me - I have worked though every thing I can, and I can't go any further because I can't see any logic to the problem.
** Since these problems have started, the TC has not backed anything up - I can't get it to back up, whatever I've tried.
** Each time I have re-made my network, when I open Airport Utility, it says 'no wireless devices recognised', and I have to re-start the TC in order to be able to do anything to it.

Try changing the Firewall setting:
mDNSResponder - Allow incoming connections
Background:
My Time Capsule was working perfectly in Leopard.
When I upgraded to Slow Leopard, Airport Utility was no longer able to see the Time Capsule - although my Mac (MBP) was still able to connect to the wireless network and out onto the Internet.
The next day or so I upgraded to Lion (Snow Leopard was only installed to get App store) - the situation remained the same.
From another Mac (MB - still running Leopard) Airport Utility was still able to connect to Time Capsule.
I edited the firewall settings on my Lion MBP:
The mDNSResponder was set to "Block incoming connections".
I changed this to "Allow incoming connections".
Airport Utility was then was then able to see the Time Capsule (I can't recall now if I needed a reboot after changing this).
HTH.

Airport used to work fine, but won't connect to internet now

Hello. I bought my Macbook pro about two weeks ago and never had problems with my internet connection. I moved last week to another city, and had my wi-fi installed today. My brother has a Powerbook G4 and it worked fine with the new connection, but my Mac won't; it won't connect automatically when I turn the computer on and when I click on "open network preferences", nothing happens. I already got connected by clicking on Network Diagnostic in Safari, but i'd like to do so without going through all that everytime I need to get on the internet.
Can anybody help me to fix this problem? I'd really appreciate that. Thanks in advance.

Tell us about your network. How are you connected to the internet? Cable modem, DSL?... Is there a router involved? Which one is it? System Preferences>Network>Show:Airport>TCP/IP are you getting an IP address?

MacBook WIFI issue. States full signal but won't connect!

Hey all,
I'm at the end of my tether here! I brought my MacBook back in Feb and loved it, was so pleased with it. A couple of months later the screen broke, so it was taken back to Comet who sent it away and repaired it, turns out the screen was faulty and there was also a "defective logic board". Got it back after 3 weeks and all was fine, until now!
When i purchased the MacBook i needed to buy a new router so i got an N router which has always worked perfectly, over the last week or 2 i found the connection kept dropping out, this happened before and it was VirginMedias problem which they fixed. I checked with them and there's no fault, checked the router and there's no fault and no settings changed, i then decided to try a neighbours WIFI, again, the MacBook connected and stated full signal but when i opened Safari it says i wasn't connected. The problem got worse and worse and i'm now at the point where i cannot connect to any network through WIFI at all, the only way i can get internet is if i use my Vodafone WIFI Dongle...which isn't the cheapest or easiest way of connecting to the net! I also have an iPhone 4 and a iPod Touch and they both still connect to the WIFI without any problems.
If anyone can help i would appreciate it so much! If i take the MacBook back to Comet they'll only want to send it away again and i'm not happy to do that, 1) Because i'll be without it for at least 3 weeks and i need it for work and 2) Since i got it back from the last repair i've discovered it wasn't put back together very well and the screws have been falling out of the base ever since.

Since you cannot connect, even at at another location, I'd agree that it seems to be a hardware problem, rather than ISP or software settings.
If purchased new or refurb direct from Apple, your MacBook came with a 1-year warranty, so you should be well within the initial warranty period.
If you're not happy with the service you're getting from Comet, escalate! Ask for the manager, and keep going up the chain until you get some satisfaction.
Finally, if Comet can't meet your needs, try another Apple authorized repair center or an Apple Store.

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.

Connected to wireless network in home, but won't connect to internet....

I have a Linksys WRT54GS wireless router. We have (1)PC hardwired to the router with (1) laptop PC & (1) iBook G4 connected wirelessly. All was working fine.
Wife opens iBook in the morning and it won't connect to the internet. Airport bars are full and says it's connected to my network, but that we are not connected to the internet. It won't even connect if it's hardwired directly to the router. I've tried reconfiguring, resetting, etc. and nothing works. But the PC's are working fine.
I admit that this is my first iBook so be gentle with the comments and my limited knowledge.
Thank you in advanced for the help!
iBook G4 Mac OS X (10.4.8)

same problem - the ibook was connected and doing just fine wirelessly to the actiontec router - had been for months - then I accepted the recent updates (using the wireless connection which was working flawlessly) and immediately upon rebooting afterwards - bam - no more wireless connection.
airport shows 5 bars strong connection and name of network is still checked in the list - but nothing will actually connect.
the pcs in the house are still connecting just fine wirelessly so the problem is not the router.
the ibook will connect using ethernet cord (that is how I am typing this now) but cannot get a wireless connection going.
somebody - PLEASE - what is the secret to fixing this?

Apple tv is connected to the network but won't connect to internet?

My apple tv 3 is connected to our wireless network but will not connect to the internet. I also cannot turn on home sharing. All the other wireless devices in our house have no problem with the internet. I have hooked the apple tv up to the computer and restored the factory defaults but that did not help. Any suggestions?

have you tried connecting using ethernet to see if it's a wifi issue ?
and have you verified that the required ports are allowed on the network ?

Airport Express wireless network works fine, but won't connect to Internet

I had a power outage and since then my Airport Express doesn't connect to the Internet although everything else seems to work. I can see the AE just fine in the Airport Utility. My computer connects to the wireless network provided via the AE, so does my iPhone, so does my wireless printer, and I can print wirelessly from the computer to the printer, so the AE's wireless networking is working. If I directly connect my computer to the ethernet connection that I use for the AE, it connects to the Internet, so I have wired connectivity to the Internet. But somehow, I can't get to the Internet using the wireless network of the AE. Any suggestions on what I should try next?

Hi there,
Try to reset your Airport Express (AX), y pressing the little dot on the back of device. Keep pressed for some seconds until it flashes. Start then your Airport Utility and go through the setup process again. This will reset your whole wireless network. This may work for you. Good luck.

My macbook pro can see the network, gets full signal, but won't connect. When I run diagnostics, it automatically connects, but only if I run the diagnostics. Why won't it connect by itself?

Macbook Pro won't auto connect to wifi, but when I start diagnostics, then it will connect. It seems it requires diagnostics in order to get connected to wifi.
any ideas

SOLUTION!
I've been suffering from this problem for a few months. I tried everything suggested by everyone, and then, today, I had a mad idea.
I used to work in a room in the house that's about 12 metres away from the router. It's on the next storey up and horizontally about 8 metres away. The problem started when I began to work in the same room as the router.
Today I became so frustrated that for some reason I walked into a room about 8 metres away on the same level - Guess what? I connected with no problem at all. Feeling full of joy I walked back to the room where the router is located - Dropped internet connection within a few minutes! Walked back to the the room that's 8 metres away and, hey presto! I have a connection. I now realise that the problem was that I moved too close to the router.
I can think of no logical explanation for my experience, but empirically it seems to work. Does anyone have the faintest idea of why this should be the case? In the absence of an answer I think I may have to start believing in fairies at the bottom of the garden - I'm just off to set a meal for them.
By the way, I don't know if it has any significance, but the router is a BT Infinity router that has replaced the incredibly unreliable Virgin Media cable connection

My iPod has wifi, but won't connect to internet(facebook, Tumblr, Wiki, ect). What do I do? Also, I have reset my router and nothing happened.

I've had a problem last night by trying to look at art, all that happened was it said Safri couldn't open because it's not connected. I start unplugging my router and such and my Mother's Iphone internet works, but /my/ ipod won't work.
Can someone help?

No, there's no firewall running.
