Airport connections spotty

Hello,
We have a mobile learning lab cart that had an airport extreme fail previously (the ethernet port stopped working). I configured the new Airport extreme to have the same exact settings as the old one, and placed it on the cart. After the reconfiguration, the client computers are now experiencing kernel panics, connection drops, and inconsistent results regarding it's network connectivity. After turning off the WPA2 security on the Airport the clients seem to be working fine.
Has anyone else experienced these issues? Should I try and wipe the keychain and network entries for the airport and re-add it (after re-enabling the WPA2). The issue is that the clients are managed, so I'll have to login to each client and delete the keychain references and re-add the access point on each laptop.
Thanks in advance for any help you can provide.

never resolved; closed question.

Lose airport connection after using boot camp and windows XP

After using windows XP on boot camp and shutting down windows and booting to Mac OS 10.5.7 I lose the airport connection and have to restart or reset my airport extreme base station. My imac 2.8 is connected to airport via ethernet. Air port is operating on 5.7 version. This is a recent development and suspect it is related to updates in windows. I do not know where to start but need to solve this problem as it interrupts the other computers on wireless. Thanks Carl

I have solved problem. It was in the windows settings using airport rather than ethernet connection. Carl

I seem to have lost some of my settings and now I cannot configure my airport connection. How do I get my settings back?

Hello. First time using this. Still trying to figure out how to post my questions. I seem to have lost some of my settings and now I cannot configure my airport connection. How do I get my settings back?

If you are using cable and a Nethear router sounds like from the information you provide before your Airport setting are setup improperly. PPoE is not something a cable service would need to work. Fallow the steps I will provide bellow, I will add some screen shots also to assist if necessary.
1 - Open System Preferences from  (Menu)
2 - Click "Network"
3 - From the Network window you are going to wanna make sure Location is : Automatic and Show is : Airport
4 - Once the Show: Airport is select you should see a window like this, my window is selected for Ethernet simply because I am no longer running Tiger but the window will look the same.
5 - You will want to click on the PPPoE tab and you should see this
6 - You're gonna wanna make sure " connection using PPPoE " is not select, if it is make sure to uncheck this option
7 - Once this is uncheck make sure to click "Apply Now"
8 - You will want to click back on to the "TCP/IP" tab and make sure IPv4 is set to " Using DHCP "
9 - If the option to " Apply Now" is available again please click this
10 - Once this is done go to your Aiport Menu and see if your network is listed and select your network and eneter the password if necessary.
11 - If after these steps you still have issues I would recommend Power Cylcing your Router and Modem for about 5 minutes
12 - Make sure all lights are off when unplugging the Router and the Modem
13 - Some Modems have backup batterys so you may have to push in a tiny button on the back with a pin

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,

Airport connected to modem but no internet.

So I have the Airport connected to my cable modem but the Airport just blinks orange the whole time and the activity light isn't moving at all on the modem and I can't get online.
I've tried unplugging the modem and Airport then like 15 minutes later I plug the modem in then 15 minutes later I plug the Airport in, but it doesn't seem to be working, any thoughts?

Alright, so I called Apple and fixed it, so for anyone else with this problem here's what I had to do.
I unplugged everything from the Airport and the Airport itself from the wall, held down the grey reset button on the bottom of it, while holding it down plugged it back into the wall and held the button till the light flashed green 3 times then went to orange and went back and opened Airport Utility and had to put in all my information again, holding down the button put it back to it's default settings.

Mac desktop and Airport Connection

I have problem on My Mac desktop. I can't connect to my airport. my other devices had no problem with the airport connection. It shows full bar on my wifi bar but when I started to browse it tells me not connected to the Internet. I've tried resetting everything but no luck for me. Please help. Thanx!

What specifically have you tried resetting? If you are seeing and connecting to your network then that's a big first step. I would try first to see if it's a settings issue. The easiest way to do this is to create a new network location and see if the issue persists. Go to System Preferences -> Network. Select the box next to the word "locations" at the top and select "edit locations." Hit the plus symbol and name the location whatever you want (I use "test" in these situations). Make sure it's selected and hit "done" and then Apply in the bottom right of the preferences page. Give it about 30 seconds and then try to browse again. If you're successful, it was a settings issue. You can now do one of two things: find the individual setting that was causing the issue in the other location, or just use the new location you've already created. You'll probably opt for the latter, which is what I would recommend. Very, very few users have a need for a particular location setting. If you're still having a problem then it may be more complicated to resolve. I would try it on another network (at a friend's house, or at Starbucks) to make sure it's not network related. Just because your machine is the only one not working doesn't exclude the network as the root of the issue. If you have problems there, I would consult your local Apple Store or Apple Certified repair facility as it may take some deeper troubleshooting to resolve.

Airport connection dropping off when computer sleeps

Starting with the latest 10.4.8 update my airport connection drops when the computer goes to sleep. No amount of configuring will get the computer to recognize my airport. Turning off the power to the airport, waiting, and re-connecting does no good. The only way to get wireless is to restart. Once restarted the airport connection is re-established without any configuration and continues to be fine until the computer goes to sleep. Hard wiring ethernet works at all times without problems.

thanks,
i read the doc, looked in the system prefs where my re-connect was set to "preferred" and there was only one wpa network listed. i deleted it from the list then re-added per the apple document. will see if this works.
in my own mind i don't think this is the solution but am keeping an open mind. the weird thing about my situation is that after the computer sleeps there are no available networks under the airport menu. i know in fact there are 4-6 in my area. after restarting the 4-6, including mine, networks are all there and my network has been connected to.

MacBookPro loses automatic AirPort Connection

My MacBook Pro used to connect automatically to my Airport Express network everytime I opened up or turned on the computer. Recently I accidentally unplugged my Airport Express. Since then, my laptop no longer connects automatically. (In other words, the airport connection on the tool bar is shaded gray...) I have to connect manually from the tool bar every time I open up or turn on my laptop. Can anyone help me figure out what to do with the settings to fix this?
The OS is 10.4.11.

I have exactly the same problem after an ATT line issue which caused my DSL line to go dead. After fixing the line, Airport would not connect to my MacBookPro automatically. So I reset AP Extreme and could then find it but once I put the laptop to sleep or restart it, I have to manually connect to AP Extreme. The G5 tower has no problems and my iPhone is automatically connected

MacBook Pro 2008 Airport connections

I know that a number of people have posted messages regarding the problem with Airport connections but I have not found a solution yet. My MackBook Pro 2008 has iOS 10.6.8. I can see Airport on (bold signal) but I can't access the interenet though I am able to use Skype. This had happened before but the problem was resolved by itself. The laptop works fine when connected by an ethernet cable. Can any one suggest any solutions please? Please note that I do not use Airport Exress or Time Capule as far as I know.
Thank you.
Prithvi.

Can your MacBook Pro (MBP) connect to other wireless network AND gain Internet access, just not yours? Regardless, when a computer can connect to the local wireless network BUT is unable to gain Internet access, it typically is due to missing or corrupt DNS server information. Think of DNS as the Internet's version of a phone book.
One simple test, is to enter the web site's actual IP address instead of its URL in your web browser. If you can now access the website, you verified that the DNS information in your MBP AirPort profile is incorrect.
Another test, is to substitute a known set of DNS servers, like the ones provided by OpenDNS. Again, if you can access the websites by their URLs, it was the DNS servers information that was incorrect.

Loosing Airport Connections - Core Duo

My AirPort connection doesn't work on MacBook Pro handed to me. No bars in the AirPort menu, no network shows.
MacBook Pro 15", Intel Core Duo, 2.16 GHz, 2GB RAM
Running Leopard 10.5.4 with all other Apple updates
AirPort Extreme (0x168C, 0x86 - Atheros Card), Firmware: 1.4.3.1
Every once in a blue moon, when the Mac was off for a while, it asks to connect to any wifi network around. It rarely connects to the selected wifi network and then only for about 5 minutes before it degrades constantly (watching it with iStumbler) and in about 5 minutes it's dead. When it connects iStumbler never shows more than about 50% signal strength.
In order to get a signal at all I must be right next to the router, only to die after 5-10 minutes. If I try to join the network, it throws a "connection timeout" error.

This happens on various networks (not just my home network with a Netgear router - mixed b/g, channel 6, WPA)
I first checked on my router (switched channels, removed encryption, updated firmware, reset everything). Tried different wifi networks. Nothing would improve it.
I've tried all of the Mac solutions I could find online:
Removing the airport prefs, booting into safe mode, turning IPv6 off, DNS entries, removing and adding the Airport setup, turned the airport utility process off (I use a Netgear router), reset PRAM, Repair Permissions...
I even reseated the card and the antennae (2) in case it was a bad connection.
I finally erased everything and installed from the original disks 10.4.6 and tried upgrading slowly (tried 10.4.6, 10.4.11, 10.5.0, 10.5.1, 10.5.3, 10.5.4), all the way up to 10.5.4.
iStumbler or AP Grapher find the network at the signal strength of about 20% while the Airport menu indicator can't see or connect at all.
Any help would be greatly appreciated.

Have you connected to the router using an ethernet cable? Try this to check that the signals are getting to & through the router. From my own experience it is most likely the wifi connection that is not working as it should.
Make sure that you also do the routine maintenance things such as using Disk Utility to repair permissions. Errors here can affect some processes.
I suggest that you also report the problem to Apple by clicking on the Contact Us link at the bottom of this page. On the screen that comes up choose the most appropriate link at the lower end of the RH column. I would include this copy of the System log. This is the main way we users have of getting Apple's attention. They don't promise any direct response but they will check the issue. You should also give them info about the router(s) you have had this problem with & any other info that might help them sort it out.

Having intermittent Airport connectivity with a 2010 6 core MacPro. Any help?

Having intermittent Airport connectivity with a 2010 6 core MacPro. When it works has low bars on status graph. Laptop set up next to it has no connect problems. Airport utility has shown no Airports a couple times when the laptop showed all. When first joined network, staus bar is full, then drops to one or two bars. Would this be an antenna or card being loose? Is it user friendly fix, or bring it to Apple? Thanks in advance.

Would this be an antenna or card being loose?
Sounds like it.
Is it user friendly fix, or bring it to Apple?
If under AppleCare, bring it to Apple. If not, you can probably find instructions to fix a loose antenna connector yourself.

IMac Loses Airport Connectivity

Hi,
I have two identical 20" Intel Core Duo iMacs (see hardware review below). One is at home and the other at work. I have been experiencing a problem on both computers where my Airport connection drops "randomly". After the connection is dropped ALL available networks are no longer available from the Airport menu, and won't become available again until after a reboot. I've tried toggling Airport on/off, restarting the router, waiting, and nothing but a reboot works. What is odd is that this exact same behavior happens both at home and work -- the router brand is the same at both locations (linksys) but the models are not. I have noticed that this occurs more often when I'm using more network resources (uploading a large file, for example), but that isn't always the case.
Any ideas as to what is going on? I don't have any 3rd party software on my machines that I believe could cause such behavior.
Thanks.

Welcome to Discussions, Scott Newman1!
There were a couple of AirPort Extreme Updates (2007-002 and 2007-003) that were meant for Intel-based Macs. I hope you have them both installed. Check your Software Update panel of System Preferences - the "Updates" half of the mini-menu bar to see whether or not they got installed. Even if they did, it will probably be worthwhile to download them straight from Support>Downloads and install them over top of what you have now. I would also do the same with the OS X Combo Update for Intel. Doing all that will not duplicate, will only fill in something missing or flawed.
After doing that, you'll undoubtedly need to delete your configuration and enter a new one using the Network panel of System Preferences. There are a couple angles from which you can approach it with some fiddling. After some fussing, a couple restarts and sitting overnight/a few hours, it should straighten itself out so that you'll never have a problem again. If not, come on back:)

Why do I have to "set up" Airport Connect. after "sleep" or logging off?

I installed OS 10.5.4 a couple of months ago. Ever since then each time I log on to the internet or just get my mail (from Apple Mail) I get a message that I'm not connected. I then have to punch a multitude of buttons to get on again. I've found no help in any sources I've been to. We're cable with a router and an ethernet on our office computer. I haven't installed Leopard on it--I'm afraid of the problems I'll have. It's ethernet.
It's the airport MacBook that's having the log on problems. Any help from anyone?
P.S. I've assigned our NetGear to be the first on the list of connections. (I have several other coffee shop type places in the list as well.) So, the problem is coming from somewhere else in the OS system. Thanks!

Is your router firmware up to date?
A quick search of the forum turns up an identical issue

Share Airport connection between 2 iBooks?

Hi there, I'm setting up a little roving trolley of G3 iBooks at school and they all have airport cards except for one. They are runnin OS 9.1 or 9.2
The ones with airport all see the internet/school network/postscript network printer just fine...
Would it be possible to connect the one without Airport to one of the others via an ethernet cable and connect to the internet/printer that way... sharing the Airport connection?
I'm more familiar with OSX so would appreciate any help!
cheers
Steve

As I recall internet sharing is not a feature in OS 9, but there was software that implemented it on those older systems. I used this software quite some time ago - IPNetRouter by Sustainable Software.

Airport connects, but still no internet activity...

Heya. This is my first post so be gentle with me.
I've recently had an issue with my Powerbook G4 12 inch where I could connect to an open wireless network (no WEP password) and my internet would function fine, until the past three days when Airport says it's connected but I can't browse the internet, use BitTorrent etc.
Now when I open Firefox, it doesn't go immediately to a "page cannot be displayed" dialog, it just keeps looking for the page for a few minutes. Also, when I run network diagnostics, everything is green until "internet".
I don't have access to the modem or router base station.
Anyone have any ideas?

I just posted my own experience in the forum "internet, networking and Power Mac G4" which is the same as the one of nofryzone. In that discussion, I think Lawrence Kahan has the answer to our problem. I will still have to try his proposed solution because it will entail changing the firmware of the linksys wrt54g router. In order to connect, I asked the help of [email protected] and they made me configure my airport connection manually placing the values that Lawrence Kahan wrote in his post. You will have to open system preferences and click on network. Configure Airport settings manually and enter the IP address 192.168.1.55, subnet mask 255.255.255.0, router 192.168.1.1. For the DNS server, you will have to get the value of DNS1 & DNS2 of your router and put them in the field for DNS server.
At least for now I am able to connect but through a static IP address and not through DHCP.
