Airport is connected w/4 bars, but no real connection or IP address

This one has me scratching my head.
MBP/2.4 GHz/10.5.4 connecting to a Linksys WRT54G wireless router with WPA security.
The MBP sees the Network and shows a strong signal, 4 bars, but there is no internet connection.
In the Network System Preference, Airport shows No connection and no IP address.
Other computers connect perfectly well.
Aside from scratching my head, I've restarted the computer, the modem and the router.
I've discarded the System Preference .plist (couldn't find a Network plist)
I've repaired permissions and run Disk Warrior to rebuild the directory.
I had a thought that it might be the VM Ware Fusion, so I disconnected it from the network and then shut down Windows and restarted: No change.
Who's got a brilliant insight this morning?

Got my own question answered by a colleague.
He had me create another "Location" in the network pane of System Preferences, then choose it and click Apply. I created a new location which I called 'Airport', chose it and clicked Apply and sure enough, an IP address showed up and all is well.
Justin said it's a network bug in Leopard.

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.

Airport remaining connected but unable to load pages

I've been using my MB for four years now and this problem has recently appeared over the last two days. The airport icon will show full bars but I will have no connection to the internet. If I power cycle the airport (menu turn off then back on) I can then continue to browse the web. This happens about every five minutes or so.
I do have other computers in my house that aren't having this problem. So I know it's something to do with my Macbook. I was going to do a reformat/reinstall but I wanted to see if there was a known solution here. It's almost as if the DNS service just stops working and needs to be reset...
Any solutions? Purchase a new card? Reinstall OS?
Thanks!

Hi!
I am experiencing the same problem! And by the looks of it some other users are too!
My Macbook is one and a half years old and I never had problems with using WiFi. I am currently using BT wireless and during the day it keeps dropping now and then.. I end up restarting the machine as the status icon shows that its fully connected with my chosen connection but internet doesn't work. After restarting several times and deleting all joined wireless connections history, it eventually works. I am getting annoyed by this now. Also, as said by the douglobue rest of the machines are working fine on wireless its only my macbook. Any help please?
Thanks in advance!

Airport network connected on full bars but "no internet connection" and missing lock icon!

this is really frustrating!
I'm using wireless in my house. when i click on my network it connects and it shows perfect connection which is full bars.
on Network Preferences it says that i'm connected to the Airport but when i go to Safari it shows "You are not connected to the Internet" so i click on Network Diagnostic where the 3 network status on top has the green indicator but the ISP, Internet and Server show red and failed.
I don't think there's anything wrong with my internet connection since I'm able to go online using my sister's computer and also on my iPhone.
There's also usually a Lock icon/symbol next to my network's name but when i'm connected to my network the Lock icon seems to be missing but it still shows full bars connection. I really don't get how it's possible to be connected to a network, but no internet connection, while i can access the internet on other devices.
Please help me out here. I've tried ways like going to library>preferences then put the system configuration into Trash, and going to Network Preferences and removing the Airport service and creating a new one.
and one more thing. all mentioned above are when i clicked on Advanced on network preferences then i clicked on TCP/IP and changed the Configure IPv4 from Using DHCP to Manually. When i'm back to using DHCP there's an exclamation point over the airport icon on the top bar and it says no internet connection.

I have an old PowerPC and a Macbook Pro running 10.6.7 sitting side by side. Both are using AirPort to connect to the internet wirelessly to the same router, but the old Mac connects with full bars, but the MBP struggles with only 2. Pls help, thanks!

Yes, I could connect them by ethernet if all I wanted to do was transfer files, but I would like to network them so I could use wireless internet. The machines are not always so close together, I did that to simplify the testing. With the very slow transfer speeds I am reluctant to move ahead with the internet step.

AIRPORT: have bars but can't connect to internet

In the last week and a half, my MBP's Airport has been really weird lately.
I haven't updated anything aside from iTunes and I think Iphoto.
My airport would say it's connected and that it has full bars, but I can't connect to the internet
This doesn't just happen to my home connection but to my school's connection too.
I've tried creating new Airport by what people told me to do (+/-) etc... and this worked for a while, but then it stopped working OR it would work then drop my connection a couple hours later.
My connection is really bipolar at the moment. It's like one moment, I log on, and I have internet... then the next moment, I don't.
Anyone else having the same problem? Help.

In System Preferences > Network > Airport/Wireless ...
... make certain Airport/Wireless is at the Top of the list. If not, there is a command accessible with the gear Icon under the box to re-order the list and put it there.
To get it to make up its mind more quickly, ask to join new Networks [√] and on the ( Advanced | Airport/Wireless ) Pane, make sure your Home Network is listed and at the top of the list.
You are not using IPv6, ( Advanced | TCP/IP ) so turn it off.
If it continues to give you trouble, use the ( Assist Me ) button. If "diagnostics" does not give any satisfaction, use "Setup" to set it up again from scratch by answering the questions.

Airport shows full bars but no networks listed, not connected

I recently began having an issue where my MacBook Pro (mid-2012, running 10.9.2) loses the wireless connection. However, the Airport icon in the menu bar still shows full bars (as if I were connected), but no networks are listed in the drop down menu.
Our other computer (a 2008 MacBook) and phones (moto G and Nexus 5) remain connected, at the same time, nor have they any similar issue. So it appears to be an issue specific to my MacBook Pro.
When I try to turn the Wi-Fi off then back on in the menu bar to see if it will reconnect, the Airport icon goes empty when I click off, but it does not come back to show the bars when I click it back on, remaining 'empty'. Yet I in the drop-down menu I regain the option to 'Turn Wi-Fi Off,' though no networks are listed.
Also, I use this machine daily at work on a university network Wi-Fi and have not had any issues (yet).
I've run Disk Utility after running into this problem, and it instructs me to Repair the Disk in Recovery Mode (via restarting the computer with CMD+R). Doing this, and sometimes doing just a normal restart, so far brings the connection back as normal.
This happened for the first time last weekend, happened again a couple days later, then twice this morning. So it's not constant but is enough that I'm seeking help.
I've scoured the system.log but don't really know what I'm looking for, thus not sure what to paste in here that would be helpful.
Thanks.

Unfortunately, I'm living in a spot in Europe that's not really near any Apple stores (and not sure I wholly trust the nearest 'Trusted retailer' to sort this out).
The more I dig through this issue, the more it's seeming to categorize with the numerous discussions already ongoing about wi-fi drops with Mavericks (here, here, and here for example). The jist of these is that there seems to be no true, ultimate "fix." I tried many of the suggested workarounds (deleting Bluetooth plist, keeping the Bluetooth off, dropping the Wi-Fi from the Network preferences pane and re-adding it, creating a new network location, unsyncing iCloud Keychain, resetting the PRAM, rebooting the SMC). None gives permanent fix thus far.
My hardware tests and Disk Utility reports still come back clean, as well.
And I'm again using this computer on a Wi-Fi network at work with zero problems so far.
Further, we still have another computer (older MacBook, running 10.6.8) and two phones connecting to the home Wi-Fi that haven't had any issues, so it's not likely as simple as a bad router or home connection.
Whether something in the configuration isn't playing nice with Mavericks, however, is an issue I'm going to try to sort out further (e.g., I've read that changing the wireless router channel has helped some people).

Airport loses connection but still shows 4 full bars

I've got a strange problem I haven't been able to figure out myself.
On my MacBook Core Duo (original 2006) on 10.6.2, my airport loses connection with my wireless router (Linksys WRT54G) after 5-10 minutes of use. My airport still shows a full signal, but I lose all connection (I cannot even see the router itself when I navigate to its IP address in Safari - normally I get the web based configuration panel). If I turn off Airport and then turn it back on again, I get my connection back for another 5-10 minutes.
I am using WPA encryption.
I get this problem when my computer is far away from the router or very close.
I do not get this problem on our other computers - one Vista desktop and and two XP laptops.
I have no connection problems when I plug my modem directly to the MacBook via ethernet.
My only thought at this point: there are numerous (8-10) other 802.11x networks in my building. I've done my best to choose a free channel, but the best I can do is choose a channel only 1 channel away from others (i.e., choose 7 when others are on 6 and 8). I wonder if signal interference is an issue...but why would all my Windows machines have no problem?
I'm out of ideas at this point - I appreciate any help :)! Thanks!

I am having the SAME exact problem with my Mac. I have a late 2008 white 13" MacBook and it's been upgraded to Snow Leopard and I'm running version 10.6.2. I am wondering if any Apple employees can assist us on this issue or tell us if the impending 10.6.3 upgrade will have a fix for this.
My Airport will be connected to my wireless network and be working fine. As MBaker22 says, after 5 minutes the connection seems fine, the IP is fine, the network is fine and the network works for other laptops and desktops in my house BUT I can't access the Internet. All of a sudden I have no ability to check for software updates, browse the web or do anything that connects to the Internet.
Some other strangeness. When I try to hit the IP of my wireless router in my web browser, it asks me for credentials and then just sits there saying Connecting to 192.168.1.1...
It also only says connecting to www.google.com or www.cnn.com or www.yahoo.com when Airport is behaving this way.
If I plug in my Ethernet cord to my Mac everything works just fine so this is an Airport issue and probably an issue with Snow Leopard? I'm not sure.
Anyway the REALLY weird thing is that I can ping some websites and not others in the terminal when Airport starts behaving this way. That might be because of caching but either way.
Here's a TCPDUMP of my connection on Airport (en1) using Google DNS 8.8.8.8 (but if I use my ISP DNS it still does this):

Getting bars but no internet with new airport extreme

HI,
I purchased a new AEBS for my restaurant. I set it up and it worked great. My Powerbook g4 was connecting and I was getting internet fine. The next time I went to the restaurant and opened my Powerbook I was getting airport bars but was unable to connect. My son has a Powerbook as well and he is connecting just fine. Several customers came in with Macs and they were also unable to connect. I know I'm getting internet from the modem. I've tried unplugging both the modem and AEBS and then reconnecting with no resolution. I've tried to re-set up the AEBS but it says it is not getting the IP address. I'm about to throw out the AEBS and go get a Linksys!
I've read other posts of folks with this same problem and one of the solutions is to roll back to a previous firmware version. How is that done?
Powerbook G4 aluminum, 1.25ghz
Thanks for any help

I have no problem gettiing the Macbook pro to set itself up on the Airport Network. I can NOT, though, access the internet. I even tried to type in the IP address for the DSL modem while connected to Airport base and can not connect to modem. Does anyone have any advice? Is there a bridging function in the Airport Base that has to be activated?
Make sure you perform a complete power recycle when switching network components.
Modem/Router Power ReCycling
- Power-off the DSL modem & AEBS. (Wait at least 30 minutes. If possible, leave the modem off overnight.)
- Power-on the DSL modem; Wait at least 30 minutes.
- Power-on the AEBS; Wait at least 5 minutes.
If that doesn't resolve the problem, and your DSL ISP requires PPPoE for connectivity, you will need to set that up on your AirPort Extreme Base Station (AEBS) as follows:
Connect your computer directly (using an Ethernet cable) to the LAN port of the AEBS, and then, using the AirPort Admin Utility, check these settings:
Internet tab
- Connect Using: PPP over Ethernet (PPPoE)
- Account Name: <ISP account name>
- Change password: <ISP password>
- Always stay connected (checked)
- WAN Ethernet Port: Automatic
Another question. If I replace my current DSL Router with a wireless router, do I even need the airport base if all I want to do it connect to the internet with the laptop?
No, the AEBS will no longer be required.

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!

Try this app, also:

G4 (800MHz) connects to airport network via N300 wireless modem but won't bring up a browser page (Safari or Firefox)

G4 (800MHz) connects to airport network via N300 wireless modem but won't bring up a browser page (Safari or Firefox) - so the connection is there, everything says its a goer - I get a clear black signal icon in the menu bar on top, and a clear signal strength in the Internet connect dialogue box - - but when I run either of the browsers, it just says 'not connected to internet' - even for the 'software update'.
the N300 is a Netgear N300 Wirelsess Modem Router (model DGN2200) - ADSL (802.11 b/g/n)

As with previous posts this is usually a DHCP issue and occurs frequently especially with routers connected to Cable Modems or those Micro-Cell towers.
Unplug all Routers, AirPorts (or other off brand Wi-Fi broadcast units) and any other Wireless broadcast unit that might provide you with a WDS (often other AirPorts feeding off the signal of the AirPort closest to Cable/DSL Modem) and best to totally power down the Unit affected; lastly either hold a reset button on Cable/DSL modem for 30-45 seconds or actually power it down if an option (not suppose to power down Cable Modems that have Telephony for some odd never completely explained to me reason).
Let Cable/DSL Modem re-boot till 'all green lights'. Then power up each device involved in order from closest to farthest waiting each time for completion of initiation. Micro-cell towers can take 10 minutes to completely re-boot and you must wait for across the board green lights in my experience. Even WDS can add a few minutes till all green on mother AirPort unit.
Only NOW may you re-start the offending device and see if it will connect. Works about 99% of the time!

Airport card connected but safari not connected to internet

Running os 10.4.1 on IMAC g5 with airport card.
i am having some wireless network issues. when i try to connect to the linksys router that my airport card locates it tells me that i am connected to the network; but when i try to load a page in Safari it tells me that i am not connected to the internet. Internet Explorer gives me the same message.
i have been able to test my airport card by logging into another (neighbor's) network (just for testing). it received DHCP from that router and assigned a 198.162.x.x. IP address for my computer. i originally had the same issue as far as being connected but safari wouldnt open web pages. i manually plugged in DNS numbers 208.67.222.222 and 208.67.220.220 from OPEN DNS.com and Safari instantly loaded web pages.
when i try to do the same on the linksys network my airport card connects but Safari once again will not connect to the internet. I am receiving a DHCP IP address automatically from that router but cannot connect to the internet...
PLEASE HELP ME (it's driving me crazy!)

Oh man... since my last post (all of 15 minutes ago) my iMac now cannot connect to the network at all. The network status menu widget shows it as being connected (sometimes), but it can't actually connect to anything.
Just as an experiment, I turned off MAC address filtering on the base station. Didn't help.

Airport will connect to network but not internet

Hi,
My MacBook air started out working beautifully on my wireless network-high download speeds, solid connection, etc... After about six hours of operation however, it has stopped being able to find the internet consistently, no matter what wireless network I try. I use a NetGear wireless hub in my room, and my laptop is able to consistently find and connect to the network (the hub is only about 3 feet away) but it cannot connect to the internet. Under network settings I get the message "Airport has a self-assigned IP address and may not be able to connect to the internet" or "Airport cannot connect to the internet." I know that the internet is working, because the network works fine for my MB Pro, iPhone, TiVo, and xBox 360. In fact, the MBA is occassionally able to find the internet and get an IP address. Sometimes this IP address allows me to load web pages extremely slow and sometimes I cannot even find google. The problem extends beyond my one network, however, as I have difficulty connecting to other wireless networks. I am on a college campus and sometimes can connect to the campus WiFi, but it again frequently connects without being able to figure out an IP address. Some help would be great.

I have a similar issue. Mine does the same thing, but only if in a specific area. If I'm sitting on my recliner with the Air on my lap, then it will connect, but I can't get to any sites. The browser just stalls.
If I move to the table that's 3 feet away from me, then the internet connects without any problems.
It could be a reception issue with me, or something. I don't know. At first it connected at very high speeds. That was before 10.5.2.
I don't know if the Leopard Update has anything to do with it, since my iMac doesn't have this problem at all. And that has an N card also.
I hope Apple is looking into this wireless issues.

Network found at 5/5 green bars, but can't connect.

Hi,
I received this weekend my inspiron 9400 with an integrated Dell Wireless 1500 Draft 802.11n WLAN mini-card.
I then went to buy a Wireless G SRX200 WRT54GX2.
I can see the network fine at 5/5 green bars, but always unable to connect. I have tried no security, wep, wpa, wpa2 with both encryptions. I have tried every channel still the same issue : Wireless connection unavailable.
I know my Dell Wireless 1500 card works because In my network list there is an unprotected network that I see sometime with 1/5 green bar that I tried to connect to and got my IP address in 3-4 seconds.
I am at the moment clueless about why I can't get any connection with my router. Wired works fine though.
Thanks,
Burnie

Yes I have tried with Firewall on and off.
I have also changed the SSID that was by default linksys to alot of other SSID's too. I don't have any other wireless devices nearby. I tried using both the Microsoft wireless utility and Dell wireless Utility.
Same result as always. Not Connected
Thanks,
Burnie

Airport is connected w/4 bars, but no real connection or IP address
