Hardware :: Airport Does Not Have An Ip Address And Cannot Connect To The Internet?
Apr 20, 2007
I have a problem with my macbookpro and connection to internet.
1 week ago my computer as stopped to connect to internet.
I was used connecting with my airport express, but at one point my macbook pro stopped receiving ip adress from interenet.
the message on the network connection is Airport is connected to the network. Airport is does not have an IP address and Cannot connect to the internet
I have try everything...:
the Airport is working becouse all the others computers inside on my office are working well with airport.
If I connect my computer with a cable I have the same problem.
I have reset and restart Airport and computer.
I have let my connection and computer disconnected and switched off for 24 our.
I have verifyining that is not an hardware problem because I have installed a fresh OS on an external drive and when I boot from the external drive everything working well.
The OS is on boot installation 10.4.9
the machine is a Mac book pro 17 2.16 GHZ intel core duo with 2gb 667 Mhz.
My problem is that on the old installation I have a lot of software installed and will be take a lot of time doing all the new installation. I wondering if there is a way to recover the situation.

Recently moved and had a net connection installed yesterday, the guy set it up and it connected fine up until last night when i decided to mess around with OSC control and had to set up my own local network to do it.
Now today I'm trying to connect to the net again back on the default 'automatic' location (i made a seperate location for the OSC to try and avoid this sort of trouble) - and although Airport is picking up the router and is saying it HAS got an IP address, the internet is still not connecting.
I've done a few common sense diagnostic checks, its not Firefox becuase I'm running Little Snitch and thats not showing any movement either..I checked that its automatically configuring using DCHP and supposedly wiped the network settings by deleting the .plist files but its still doing the same thing: reporting that it's connected and has an IP address, but still with no connectivity.
Diagnostics says it 'appears to be connected' but the Network Setup Assistant gets to the last stage of the setup and asks me to check my diagnostics because it can't connect. When seconds later it has an IP and is 'connected'.

Router is a Netgear VMDG280

I've read about a thousand threads and can't seem to find a solution to my problem: my computer is able to recognize my Airport network and it has the green signal next to it with the full signal strength, but when I select it, the internet doesn't work. I'm using a Macbook OSX with an Airport Extreme.

I've been looking around the internet for a solution to this problem. I'm currently in an apartment with a single wired connection running to my Macbook Pro, i haven't got time to buy a switch or router right now and i've been trying to connect my 360 to the internet using Airport. All of the how-to's i've found so far concern connecting the 360 and Macbook via Ethernet rather than Airport, and while i've tried to follow the steps as best as i can i haven't been able to connect to xbox live.

I haven't been able to connect to my school's internet and every so often when I am at home I will have to turn my Airport on and off to get it to connect to the internet(sometimes it's rare and sometimes it can happen up to 3 times a day). Is there a way to troubleshoot this to see if there is anything wrong with my Airport or if it is just a problem with my connection at home and at school?

This has been happening ever since I bought my Mac. I have reset + configured my router SO many times already and nothing is working. Can anyone explain why this is happening and/or what can I do?
The router is a Linksys WRT54G. Mac is running 10.6.2.

I've had this simultaneous dual band APX for a while now and have just been overlooking this problem, but now I really just want to resolve it. Basically it will not connect to the internet when plugged directly into our cable modem. In order for it to work, I have to leave our old Belkin wireless router plugged in between the APX and cable modem.

I cannot connect to the internet after the last airport upgrade and Airport Extreme firmware upgrade. I can connect wirelessly to the Airport Extreme using my iMac (27", mid-2011), but cannot connect using my 11" MBA ( late 2010). When I use the adapter and connect the MBA with an ethernet cable, I can get online briefly with a restart, however the connection is lost within two or three minutes.

I cannot connect to Internet via my MBP (late 2013) through my Airport Extreme. It will connect to the AE fine, but the Airport Utility will show that the AE is not connected to the internet. Which is a lie, because other devices (iOS, Windows) will connect to internet through the same AE. working on the MBP under Bootcamp. So we can also rule out hardware issues with the WiFi chipset. This must be a MacOS (Mavericks) related issue.

It could be a firewall setting. It could be a software update. Whatever it is, I cannot connect to the internet using Extreme (it does connect to the internet using just plain old wifi). This is a sudden problem--it worked fine last week.
I'm using OS 10.5.2.

I currently use a Powerbook, and I access the internet though our AirPort Extreme router. Recently, for some reason, although I am on the right network, and signal strength is full - I am unable to connect to the internet! I've called my provider, and everything is fine on their end according to their systems. I've tried power cycling, and checking my settings, and everything SEEMS to be ok.

I have an aiport extreme card in my emac. It was installed around a year and a half ago and has workd fine until yesterday. it suddenly says that it is not configured. It also says the antenna cable is unplugged and that it is turned off. I tried to trouble shoot it with internet connection assistant which says cable is unplugged and aiport is off.

I have a macbook a little over a year old. It's my first mac and I love it. Yesterday though it started acting really weird. I first noticed that it was really, really hot and the fan was running. I turned it off and back on and here's what I found out:
Applications are being deleted from macbook. ITunes, IPhoto, iChat have clear question marks over icon. There are 8-10 blank spaces in the Applications folder where applications have been deleted. However, data is still there (ex. pictures still there, but no iPhoto).
Internet= Says I have internet but wont connect.
Cannot open " System Preferences" or "Internet Preferences".
If connected to home computer will connect to internet and allowed to open internet preferences but still no system preferences.
If shut down....takes a while to come back on and starts up 2-3 times.
Also "Preview" is gone. Now " ColorSync Utility" opens.
Is this my hard drive dying? I'm tech challenged, so any help would be greatly appreciated.

I'm running OSX 10.5.8 on a Macbook Pro, and today I've been unable to connect to the internet via ethernet or wi-fi, unless I'm in safe mode. Then everything seems to work as it should, which makes me believe that this is a software issue rather than a hardware problem. I've tried making a new account with administrator priveleges, but that doesn't solve my issue. Does anyone have any advice on how I can connect to the internet under my normal user account, rather than in safe mode? I should note that I won't be able to get my hands on my repair CD or perform a clean install of OSX because that stuff is at home, and I'm in college. Also, I'm at a university and don't have a router. I just use the campus-wide wi-fi. Finally, my roommate has no problem accessing the internet in our room via ethernet or wi-fi, but I do. Thanks for the help everyone.

currently I connect to the internet by doing this: Go to System Preferences / Network. Then I select my internet provider name on the left pane and finally click on the Connect button. That's all. This internet profile has a PPoE service name, an account name and a password. My internet connection uses a cable DLink router (it's not wireless).
Question:
1) Does the password I mentioned above mean that my neighbors can't access my internet, or are they able to do that and, in this case, I need to set another password somewhere else?
2) If I need another password, how and where do I set it,

I have a blackbook (intel core 2 duo) and I can connect to my landlord's wireless network (they have a netgear wgt624) but I can't actually use the web (Safari or Firefox will just "think"). I've tested the diagnostics and it confirms that my mac can connect to the network, but it cannot connect to the internet. The network uses WPA personal and it has a 19-aphanumeric passphrase.
*Also - would it be possible for me to extend the wireless range (and make it possible to browse the web) if I used my own 2wire wireless modem to connect to the netgear wgt624?

Development of Apple's upcoming Mac OS X 10.5.5 Update appears to be winding down, with only a couple of new fixes making their way into recent builds, including one aimed at wireless issues.
This past week saw two new pre-release distributions of the 320MB Leopard update fall into developers' hands. The first arrived mid week as Mac OS X 10.5.5 build 9F25, but contained no noticeable changes from the build the preceded it.
More recently, developers were treated to build 9F29. That build tacked on a pair of fixes, one of which tackles an issue between Macs and previously joined AirPort networks, people familiar with the software say. The second fix was related to a graphics framework.
Seemingly at the tail end of its development cycle, Mac OS X 10.5.5 is reportedly hindered by a single known bug that prevents emails from being searched properly in Apple's Mail application.
The fifth maintenance and security update for Mac OS X 10.5 Leopard now stands to deliver 125 bug fixes when it's released later this month.[ View this article at AppleInsider.com ]

Well the problem started when we got a new Time Capsule (2 TB) and replaced and AEBS. At the moment we have 4 macs using the TC. Three wireless and one connected with ethernet cable. If I close the lid on my Macbook Air and open it after a few minutes, it wont connect to the internet. I get a message saying: "Airport has the self-assigned IP address (and the IP #) and will not be able to connect to the internet" I try to use the network diagnostics, and it looks like the network settings is wrong (amber light) and the internet and server is failed.
I then select the network I want to use, and then it suddenly works again. Also three of the macs are using the TC for back ups. Usually the back up gets delayed, and wont start even if I ask it to back up now. It starts to the volume ready, then it says that the disk isn't available. Is there something I cant do or is the TC faulty? My mum and dad arent too good with macs, so if they cant connect to the internet they usually just reboot and it works. I have reset the TC and created the network again, but its still the same issue.

Hope someone can help me with this - have seen similar-ish issues in past posts but nothing that can fully help me.Basically I have just moved in to a new houseshare - there is WIFI in the house, cable broadband (NTL IRELAND).On my Macbook Pro (2007) I am having an issue connecting to the internet. Had the issue on Leopard and, now, on Snow Leopard.I connect to the home network, but cannot get internet. I tried with DHCP, but Airport says I cannot connect due to the IP address being self assigned?

First off I'm not very literate in security issues or computer terminology so I'm sure I am going to come off as a complete moron but can anyone tell me what the security risks are if someone has my IP address. Can they access my computer? Can they access my internet based email? Can they find out who I am? If I access a forum through a link from my internet email can the administrator of the forum (or anyone else). Hack my internet email? Hack my computer? Find out who I am? I have a Powerbook G4 and I'm running 10.4.11.

I just found an old mac in my room, I think it is a power mac g4, it is running OS X 10.3. I am trying to get it connected to the internet using a cable straight from it to my router (netcomm), the same way i do with my other mac. However, no matter how many different variations i use of my various settings, it wont connect. I have come down to needing a subnet mask, IP address, and router address.
I am almost certain i have the subnet mask and router addie correct, but there seems to be no way for me to find the g4's IP. I have been in system preferences, but all the 'IP' bits are just blank and unclickable. I don't know if it makes a difference, but the G4 was connected to the internet in the past before we upgraded, so it should have an IP somewhere, right?

I have a wireless router with 2 devices connected via ethernet (PC and XBOX 360) and 3 devices connected wirelessley (Imac, macbook, iphone and printer). This morning I was using my imac and all of a sudden I got a message saying another device is using my IP address.
I tried restarting the router, the computer airport but nothing worked. The only other device on at this point was the macbook which received the same message. I assigned a manual address to the imac via the advanced settings in airport but how do I fix this so that IP addresses are assigned automatically?

About a week ago my internet connection would drop out for hours. After setting messing around with my router and modem and reseting everything it would work for a few hours then stop again. My connection is provided by Charter Cable, through a Linksys BEFCMU10 V4.0 modem, to a Linksys WRT55AG V2.0 router. If I removed the router and wired directly into the G5 from the modem, the internet connection would start working perfectly. If I went back, reset the router and hooked it up again, I would lose connection and it would actually take the modem completely offline, requiring the modem to be reset to get reconnected. So I decided I would spring for an Airport Extreme Base Station, figuring the router was bad.
Well I get home with the new AEBS hook it up, and does the same thing. Apples menus and troubleshooting guides. (The main reason I decided to get the AEBS) Well after going through the setup, it says it is not receiving an IP address.

I have a MacBookPro running OSX 10.5.8 and I've been connecting wirelessly with my NETGEAR Wireless N Router (WNR2000) for the past week but then all of a sudden I'm not able to connect to the internet anymore. I keep getting this message "you have a self assigned IP Address but may not be able to connect to the internet."
I've done all the basic troubleshooting with resetting the Router to factory setting and also unplugged and restarted my modem and Router and laptop.
I've called my ISP (Time Warner Cable) and they've gone through the same troubleshooting with me. I know my internet works as I've been using Ethernet and it works. The person over at Time Warner and she said that my internet and even Netgear wireless router is giving the right IP address but when i checked my network settings on my computer, the IPv4 address is this: 169.254.52.45.
I've checked on various sites and i found that IP that starts with 169.254.xxx is the default setting for airports. I don't know how to set the right IP on my airport on my laptop? It's annoying because I've tried setting my airport on my laptop USING DHCP with manual address with the correct IP from my ethernet connection but doesn't seem to work. I'm at the end of the ropes before smashing my router and computer to a million pieces.
