Airport will not connect to my home network after trying to connect to my school's network. Need help!

Airport on my Macbook will no longer connect to my internet network at home. I was on campus using my university's network today and now Airport only wants to connect to it and will not change back to my home network. It has something to do with the 802.1X, and I don't know enough about networks to know what that does. Is there someway I can just reset my entire airport settings to where it would be like the first time I used my Macbook and configured it to my home network?

Did you Shut Down the Mac and then power it back up? Can you connect to your home network now if you click the fan shaped AirPort icon at the top of the Mac's screen?
If your home network name does not appear, click Join Other Network, then click Show Networks.
Click the name of the network that you want to join and enter the password if required
Are you saying that you want to delete the connection to the school network from your Mac? If you do this, you will have to setup the connection again if you head back to the school.

I installed a new wifi router and airport will not connect automatically to it. It sees the network but will not connect unless I tell it to.

I installed a new wifi router and airport will not connect automatically to it. It sees the network but will not connect unless I tell it to. I can't find anywhere in the utility or network preferences that will allow me to choose this router as the default. How do I fix this? BTW I'm using Lion.

Are there any previous networks that you have used that have the same password as Molly? YES
Using System Preferences > Network > AirPort Advanced again, you need to remove any listings of previous networks that used the same password as Molly. Click the name of the network and click the - (minus) button at the bottom of the list of connections.
Also delete any other networks (except Molly at the top of the list) that might have used the same name...Molly in the past.
Delete any other networks that you no longer need so that your Mac will search for networks more quickly
Click OK, then click Apply
Open KeyChain Access and look for a listing of any old networks that you no longer need. Click to highlight the name of the network, then click the Delete Key on your computer.
Then look for any old networks that might have used the name Molly in the past and do the same for them.
Then look for any old networks that might have used the same password as the password for your "new" Molly network and delete them in the same way
Click the KeyChain Access menu just next to the Apple icon in the upper left corner of the computer screen
and then click KeyChain First Aid
Enter the main administrator password for the Mac you are using and highlight the Repair button. Then click Start. You will see a message that repairs have been completed
Quit Keychain Access
Power down the entire network...all devices...order is not important
Power up the modem first, then your main router, the other devices one at a time
Log on to Molly and see if the Mac remembers it after a few tries. If not, I'm afraid that you will need to change the name of the wireless network and password on your router due to corruption issues on the Mac. You have done everything possible without re-installing the complete operating system.

Airport will not connect to Wifi after Restore

I do not remember the exact verison, but my Macbook was upgraded to Snow Leopard and connected to my Verizon router (WPA security) just fine.
I decided to restore my Macbook back to factory settings and inserted the install disk and went from there.
After my Macbook was restored. It reverted back to 10.4.8 (Tiger) - which was to be expected. Now my Macbook will not connect to my router, saying there is an error.
I'm at a lost right now on what to do.

Airport will not connect to wifi - time out

Hi, I have an iMac that will not connect to my network. I get the greyed out network signal in the menu bar. When I try to connect to my network (it has a black network signal icon) it asks for the password and then times out trying to connect.
The modem is working because I can connect with my MBP.
I have re-booted, repaired permissions, booted, deleted com.apple.airport.airportutility.plist, re-booted.
No luck.
The internet connection cutting out has been happening for a while - it usually comes back after a restart.

IStumbler finds my wireless router, but airport will not connect

Hi there
Had a search around this forum, but nothing seems to exactly match this confusing situation:
My airport connection to the wireless router has, over the last few days, been becoming increasingly flaky and intermittent followed last night by a total refusal to connect.
It had been working fine for at least a year up until recently.
The funny thing is that iStumbler finds my router(as well as some neighbours'), and reports a signal strength similar to what I have always had.
Problems started as follows:
iMac would show full bars, then no bars and then full again, followed by a slow drop to nothing. Turning airport off and back on again, would repeat this process. Occasionally, the iMac would also require the WPA2 password.
And progressed to:
Over a few days things got worse to the point that I had no usable connection and the airport would not always pick up any networks and would request the WPA2 password repeatedly always followed by a 'Connection timeout'.
I would say that the airport extreme card is broken, except iStumbler is reporting 'normal' service. Also, my iPhone reports full signal strength sitting next to the iMac!
Can anyone shed some light on this?
Typically, Applecare expired all of 2 weeks ago!!!

Which Airport are you using? If AirPort Extreme(802.11n), have you tried its diagnostic tool the +AirPort Utility.app?+ Same is located in your Utilities folder.
What about the OS Airport diagnostic tool? Same is located in:
System Preferences>Network
Show: Network Status
Bottom of window click on the "Assist Me" button.
Next window that pops up click on the Diagnostic button.
Have you contacted your ISP? Make sure the problem is not on their end.
If using Apple's Airport, suggest that you cross-post in one of their AirPort Forums where the AP users hang out.

Macbook will not connect to any form of internet PLEASE HELP ASAP!!!

Can someone help me. I have no idea what to do. I recently bought an Apple Mac Book 1.83Ghz. It was slightly used. It will not connect to the internet, at all. It will connect to my wireless network, and have full signal strength. But when I open safari, or any program requiring internet, it says there is no connection. I have hooked the computer stright up to my cable modem, and it still said no connection. Look I really, really need help. I don't know what to do, and I need to use this laptop asap! Please, if you see this try to help me. It will not connect at all. Please, please help.

Yes, I did. I have a linksys wireless G rougher, and an optimum online cable modem. The cable modem is hooked upto the roughter. I plugger a cord into the roughter, to the computer and that didnt work. I plugged the laptop stright into the cable modem. The modem says there is activity, but it still wont connect. What is important is the wireless. It says that it is connected to my network, but will not go on the internet. I tired setting it up with the progam installed, but when it asks for my network and password, it says that it is inaccurate. I really really need this to work as soon as I can. If you could help me in any way, please do so.
Thank you so much.

Airport will not connect to wifi (no IP address) router is working!

Hi
I need help. I have had same router for 2 years now and recently my macbook pro has been unable to connect or stay connected to internet. It either states connection timeout or no IP address. I have just come bak form mac store where they reinstalled operating system.
Please help - I have also spoken with Netcomm (router company) who confirmed everuthing is ok on their end

OP
A much easier advice that basically requires no thechnical skills, go to you nearest "Starbucks", neighbor, office or equivalent. Any place with a WiFi you can access. If you can connect there, the issue is most likely on the router-side of things.

What does the region setting in Language & Text have to do with connecting to or not connecting to a WiFi signal/network?
Well, it should not affect anything. But there is one issue you probably have not seen. I could not get a stable WiFi connection for almost a year, and this solved my problem. According to others here in the forums, this has solved the issue for them as well. It is a software issue, if you change individuall settings in the language formate your region gets set to "Custom". So, if you check your logs while connecting to the router you get a "country code" called X1 to X5, a "spare" code available for non-registered regions. Some routers cannot handle this and the symptom will be that the connection times-out or you keep getting prompted for your password, over and over again. The region should not matter, as long as it is not set to custom "Custom" with an "incompatable" router. As you said, as long as you have a "real" region, there is no issue. While connected through ethernet cable this affects nothing, only WiFi.
But thanks for your opinion...
And the Default IP for most routers on the market is not 192.168.0.x(xx). It is 192.168.1.x(xx). The only time I have seen it different was on Apple Airport products and that is 10.xxx.xxx.xxx.
Well, I don't know what your experience is, but in my book most personal users buy Linksys, Netgear or D-link, all of which has 192.168.0.1 or 192.168.1.1, feel free to check manufacturer info on this. OP: Google manufactorer and/or model AND IP and you'll get the adress you need.
So please follow John Th's advice. Thanks
The last thing I would do is Assign a Static IP address to your WiFi connection. There is a Hardware problem that needs to be fixed. Whether it is on/in your Mac or your router I don't know.
Well, I guess manually accessing your router and re-writing system information is less dangerous than clicking "new" on you locations menu, and it sounds much less complicated... But I agree, if you region is not "Custom" and you can access any other public/available WiFi, listen to John Th. But why would a static IP be "the last thing you would do"? Especially if you add this as a "new location" which can be easily deleted and revert to automatic without issues...
OP
Since I generally tend to take it personally when someone inferrs that I am incompetent, I'll leave this discussion here and stop following/commenting. I whish you the best of luck with solving your WiFi issues.

Airport will not connect to IP address

I'm a new user to Mac. I set up the internet just fine in when I received the computer a week ago. Now, I will be connected and the internet connection is just "lost" but the PC runs just fine. Airport will always be ON at this point, but it will not be connected to the IP address. We have wireless through the cable company and it just tells me to restart the device when I run the diagnostics. I will restart the router and modem and then it works just fine again. But within another 5 minutes, it will just completely stop connecting. Is there any way to put in the IP address and does what does it mean when it says Airport has self-assigned IP address and may not be able to connect to the internet. Thanks!

Sounds like your Mac is being dropped by the wireless modem/router and in doing so assigns itself an IP address to maintain internal network services. This is normal behaviour when your Mac fails to negotiate a connection with the DHCP server. Start by checking the quality of the wireless connection, in the menu bar click on the Airport triangle while holding down the option key (alt).

My airport will not connect to the Internet

I am trying to set up my airport express. I have set the Internet connection to Ethernet to reflect my satellite modem and dhcp. The airport express connects to devices in my home but not to the modem. I have tried to adjust the settings but it refuses to connect to the Internet. I have no idea what to do and there doesn't appear to be anyone who can help. I have two apple mobile devices and a desktop and laptop computer running windows seven.

Sorry, I found the error, FIXED

Airport will not connect to Linksys router after iDisk sync force quit

Hi,
Hoping someone can help me here, kinda at my wits end.
A week ago I was video ichatting and restarted my MacBook because the video feed was sluggish. I thought a restart would help.
Unknown to me was that my iDisk was syncing. I recieved an warning dialogue box and was given the option of canceling the restart or force quitting the iDisk sync. I choose to force quit and proceed with the restart. After choosing to continue with the force quit I received an error message, it had the phrase "Mirror Agent" in it, and then my MacPro restarted.
Since that first restart, I have not been able to connect, using Airport, to my Linksys Wireless router (model # WRT54 GX4).
This is where it gets strange. Airport sees the router, displays a signal strength, shows up on my list of perfered networks...it displays all of the signs of a fully connected router but when I try to access the web, check mail or use iChat I cannot because Safari, Mail and iChat tell me that I am not connected to the internet.
When I ran the network dianogistic tool, it first asked me why I would want to run it because it thought I was already connected. After running the tool it still came back with the same results, I was connect to the internet. But I still couldn't launch Safari, it just hung.
This is where it gets really wierd. My wife, she's on a HP, can connect, using her built-in wireless card. Even after changing the Firmware on the Linksys router, her pc can still connect.
And here's the icing on the cake. There are some unprotected wireless networks on my street. I can connected to those but not my own! Something has to be blocking the signal between my AirPort card and the Linksys router. Does that make sense?
And if there is one saving grace to all of this, I still can connect to the web using the built-in Ethernet.
Here's what I have tried:
Removed Perfered Network, restarted MAC, added network back, still no connectivity.
Removed security (was using WPA/WPA2) from the router still no connectivity.
Removed Airport Keychain, restarted MAC, added router back, still no connectivity.
Repaired the permissions on my HD, someone at work told me to try that, still no connectivity.
Updated firmware to Linksys router to version 1.00.20, no connectivity.
Rebooted Linksys router and cable modem, still no connectivity.
Thank you to all in advance for reading my rambling note and forgiving my poor spelling (it is way past my bedtime and the keys are really blurry). I am still very new to Mac's and appreiciate any help that you can provide.
Cheers,
Alan

Sounds like you have two wireless networks on the same channel.
Change the channel on the Airport Express.

Airport will not connect to the Internet after putting the airport into nat porting and putting the Xbox 360 ports in

When trying to set up port forwarding for Xbox, I lost Internet when I updated the new settings. When I removed the port forwarding and unchecked the nat box, the Internet ip came back. Any help would be appreciated.

I had a chance to bring it in to the Genius bar today. My worst fear was that after everything I had tried, it would work at the store. It did. ("Are you sure you plugged it into the port with the circle?") Luckily, it died after about 2 minutes, which apparently was what it had been doing. So the Genius worked on it. And worked on it. After my 8 hours of troubleshooting, it was almost worth it to see a Genius stumped. A half hour later, he decided that the Airport was toast, as I had suspected. It would cost him $300 to order a replacement, so he said to just get a new Airport. The new Airports are not cheap. We ended up getting a Linksys WRT54G for 50 bucks, and I set that up in a few minutes. I got a cool-looking broken Airport out of the deal, though, which will look awesome, even if it doesn't work.

Mac OS X Version 10.4.11 update required but it will not connect to the new fibre optic broadband , help , thanks

Problem = Mac OS X MacBook with Version 10.4.11 used to connect to the Internet now it does not
Recent Broadband upgrade to fibre optic by Eircom
Rang Ericom they cannot sort it out and suggested I contact Apple for an update
Update is not possible without internet connection
What do I do ???
Thanks

You sure your mac ethernet port works.
Give them a call. Verify that they only support windows for coniguration of router. Ask them about future support. If they have heard of the ipad. Ask if they plan on supporting a web browser interface. Ask about their sanity. My $5 router supports a web browser interface.
You could get a cheap wifi router with ethernet ports and with a web browser interface. Connect you mac to you el cheap router. Connect your el cheapo router to the eircom router. Note: Apple routers have a propriety interface too and unless you have a new Mac best to avoid.
Could they switch you to a router that supports a web browser interface?
Get a friend with a windows laptop and ask to come over to get things working.
Internet support is standardized. You mac should be able to access the internet through the router.
What is not standardized is how you configure your router.
Unbelievably, eircom_799 referenced by Neville Hillyer only supports windows for configuration.

Airport will not connect to my preferred wireless network

Hi,
I set up a wireless network in my house. My mac connected has connected to it before, but when i had to restart my computer I can no longer connect to it again.
I have added it under my preferred networks and it is top of the priority list.
Every time i try to reconnect it, my comp tells me "connection timedout", therefore not letting me reconnect to it. My router etc appears to be working properly as i can connect via ethernet.
I have tried deleting the preferred network and re-adding it, and rebooting my computer. Nothing seems to be working.
Someone who know about computers please help i have work that needs to be done!
Thanks!

Thanks, but it didn't work.
My mac remembers it, but doesn't remember the settings (ie on the preferred list). It tells me that none of my preferred networks are available, even though my network is still in the preferred list.
So i click on my network when it tells me that none of them are available and re-enter my password and it always says connection timeout.
It was working perfectly earlier on today, like i said when i restarted my computer, it automatically connected to another network and i haven't been able to get on to mine since!
