24" C2D Airport Issues

Hi All-
I've seen many posts relating to all sorts of airport/intel problems, but none that specifically seem to duplicate my own and was wondering if anyone had any caveats aside from waiting for an update from Apple. I'm currently, and preferentially, hardwired to my home network so this is based on principle, not out of necessity. I turn on the airport card in the iMac and am greeted with 8-10 wireless networks in range- one of them being my own. Of all the networks that the iMac can 'see' I can connect to all the open networks without a problem. However my own always gets an error, "there was an error joining this wireless network." I have several other devices that connect to this network without issue (tivos, ibook, airport express, pc laptop...) and unless there is some software issue or perhaps a hardware issue with the new card in the iMacs, this doesn't make any sense. I have a westell dsl wireless router (supplied by my ISP) that is configured for MAC address filtering but is otherwise open- I'm sure that I've added the MAC addresses of the iMac! It operates @ 802.11b and g for the assorted devices and that's about all I can think at the moment in terms of setup. Thanks for any help.
iMac 24" 2.16Ghz Intel C2D Mac OS X (10.4.8)

I have solved my problem. There is an incompatibility with all Intel iMacs with Airport cards and the Verizon Online supplied equipment, the Westell Versa Link 327W. Quoted from CNET:
"Several different wireless connection issues are plaguing users, but so far only one of the issues has a fix. If you aren't able to connect to your wireless network and you're using a Westell Versalink 327W router, then that's the problem. The Intel iMac doesn't seem to be compatible with it, so you'll need to switch to one from a different maker. An AirPort Express Base Station is pricey but will certainly do the trick"
Thanks to everyone that looked. I knew I wasn't crazy .

Anyone with a 17" MBP C2D having AirPort issues?

Most of the reports I've seen of people having issues with their MBP C2D and AirPort have the 15" MBP C2D (myself included.)
Has anyone with the 17" MBP C2D had issues, or is it isolated to the 15"?

Hi William
I had a 2.33 15"MBP 2.33and had no probelm with the airport reception (until security update 2006-007 was installed - I erased and reinstalled to get rid of the update and my machine went back to working fine.) Apple have released an update for Airport on the 15". So using software update the machine installed the airport update first, then installed security update 2006-007. Airport worked great.
Due to an excessively grainy display, my reseller allowed me to return the 15" and upgrade it to the 17". Again, this machine has had absolutely no airport issues. Connects full signal to whatever network I have attempted to connect to without issue.
So, I have had both a 15" and a 17", neither of them have had any airport issues, other than the one mentioned above in regards security update 2006-007 on the 15", but Apple did launch an Airport update which fixed this.

MBP Santa Rosa Airport Issues w/ Leopard

Hi everyone,
I've noticed a few "quirks" since upgrading to Leopard. Whenever my Macbook Pro (Santa Rosa, 2.4 GHz, 17", 4GB RAM) is searching for a wireless network to join, the system becomes completely unresponsive. The mouse pointer stutters and jumps around the screen and it's impossible to precisely control its movement. When I can finally manage to click on the Airport icon in the menu bar and select the appropriate network to join, the problems stop as soon as a connection to a wireless network is established. It only happens when the system is searching for a Network. I should mention that it does this when I am at work (where I connect via 802.1x and TTLS) and at home (where I connect via an Airport Express Router).
Also, my computer no longer automatically connects to my work network (it does at home, though) after a restart or waking from sleep). I have my MBP set to prompt me for a password when it wakes from sleep, but it's near next to impossible to enter in the password because the system hangs so badly as it tries to establish a network connection. Of course, it doesn't connect unless I manage to click the Airport icon and specify the network I wish to join. Anyone have any thoughts on this?
All of this is a little frustrating since the latest updates to Airport in Tiger fixed all of the connection issues I had had previously with my MBP. When I first bought the machine I had many issues with network connections (as did many thousands of others who bought this model). I was wondering if other MBP Santa Rosa owners have observed similar behavior since upgrading to Leopard, and if so, does anyone have any suggestions as to how to fix this issue?
I should also mention that my Mac Mini C2D 1.83GHz (latest model) has no such issues so I think this is something that is still linked to this particular model of MBP.
Many thanks!

I am moving this over here, from the boot camp section. Hopefully this is more the location that this needs to be in. Well, my problem is not as extreme as some, but still an annoyance. I installed Leopard the first day, and immediately had HUGE airport issues. The computer would lose my hub. I run an Airport Extreme with an Express as a WDS. The computer would see the express, but lose the extreme completely. So no internet. If I messed with it long enough, I could get the computer to recognize the extreme, but as soon as the computer went to sleep, it would lose it again. I installed the keychain update, and the situation didn't get much better. Most of the time I get the "You are not connected to the Internet" error in Safari, and when I run network diagnostics the computer "finds" the internet again, and I get a "Network configuration change detected" message and all my lights go green.
After I installed the Keychain update, I repaired disk permissions. Any ideas?

Airport issues, and "home" folder question

I'm having a problem with airport utility on my Macbook pro with OSX 10.5.3. It somehow turns itself off, and cannot be turned back on unless, the computer is restarted. Once restarted, it only stays on for a few minutes and then is turned off again. I have a time capsule, and when time machine attempts to back up, it seems to trigger it. However, even with time machine turned off, it still gets turned off. I took it to a genius bar, and the guy there seemed to think making a new account would fix it, but it didn't. It actually created another problem. He deleted my old account but saved the "home" folder. When I log into my new account, I can't access any of my music, documents, photos, etc. How do I get stuff from the saved home folder, to my new home folder???

Hey Thanks for your replies. The airport issue is being resolved. I was on the phone with applecare, and the problem was actually something with the power supply. For some reason it wasn't supplying power (or enough power) to the airport card, and that is why it would shut itself off and not turn back on. So it is being serviced right now.

Airport Issue After Waking From Sleep (White Unibody MacBook)

Hi all. On my new white unibody MacBook I have an Airport issue that always occurs after I wake the MacBook from sleep. I'm wondering if any of you have a similar issue and/or might not how to solve it.
Basically, when I wake the MacBook from sleep, it connects to my wireless network (and to whichever network I happen to be using at the time). A few seconds later, it will drop the connection, an exclamation mark will appear on top of the Airport icon on the menu bar, and when I click on the icon I see "Alert: No Internet Connection."
Then, if I just sit and wait, eventually Airport will connect to the network. But I have to wait -- selecting the network from the available list or turning Airport off and on doesn't help. And sometimes waiting isn't enough -- I sometimes have to go to "Create Network ..." and start all over to get a connection.
I've upgraded to 10.6.2 and the issue persists. I'd appreciate any help.

My wife's Macbook has EXACTLY the same problem and I've been through dozens of suggestions trying to fix it and the problem still persists.
The problem started right after I upgraded to Snow Leopard but also installed an Airport Extreme router and WPA2 wireless encryption. I've deleted all the networks, changed the order to put the Airport as the highest preference, deleted all the keys on the keychain, ran DiskUtility, all to no avail.
I'm not sure if this is somehow related to the Airport Extreme or occurs with any router. Also, have another MacBook Pro (unibody), and it does't have this problem connecting to the same Airport Extreme.
The other factor is it is intermittent --- and doesn't always fail. Rebooting the Macbook or the router will get it to re-connect, as will shutting off and turning on the Airport several times. But that's not a solution to the problem.
Apple needs to pay attention to this as many people are now reporting the problem.

Weird airport issue

i'm not quite sure if this is my computer or the network i'm using, but i'm having some weird erratic airport issues. i am on a wireless network at my university, and it usually works just fine. however, a few weeks ago it sporadically started to drop the connection (making my internet slow to non-functional, 1 or 2 bars of signal). the thing that's weird about all of this is that when this happens and i click on "open network preferences", the internet then picks back up without me doing anything further than opening the preferences window. it only lasts a minute, but every time i open the network preferences it somehow jump-starts my internet again (making me think that it's possibly my computer, not just the network). this is probably a stupid question, but i am not entirely savvy with the inner workings of my macbook. i have a 15" macbook pro, and i got it around march of 2008.

Well I tried changing it but to no avail.....
Another piece of info. It's not running N it's running b/g.

Slightly different airport issue

I've seen a lot of topics already about airport issues, but mine is slightly different. My computer has always had issues connecting to my Linksys wrt54g (802.11g). For a while after we switched ISPs it was better but not perfect. It would cut out for a while and I'd have to restart the router and modem to get signal back up.
Now my computer simply won't recognize my network at least 5 times an hour, probably more. Also, it now has this issue with the network at school. I don't know of anything that's changed to make this happen. At home I now rely on ethernet.
Could it be something wrong with my Macbook Pro 1,1's airport card? Could it be worn out? Can I replace it?
HELP PLZ!

Do you have any other computers connecting wirelessly to your router? I seem to remember seeing MANY issues with the WRT54G router and Macs. Possible that your router is bad as well. Your MBP being the problem is not the only possibility.

MBP C2D + Airport Express + WPA frequently loses connection. but WEP OK

many people seem to have wireless connectivity problems with their MBP
-- here is the problem I see with my 2wk old MBP and my wireless setup at home (Airport Express) and at work (Linksys, model# unknown):
1) MBP C2D + Linksys + WEP = no problems
2) MBP C2D + Airport Express + WEP = no problems
3) MBP C2D + Airport Express + WPA = frequent dropped connection, and poor range
for reference, my previous laptop:
4) Pismo + Airport Express + WEP = no problems
5) Pismo + Linksys + WEP = no problems
with WPA (whether WPA or WPA2) and the MBP, I turn on Airport, signal looks strong, but then suddenly disappears. I have to toggle Airport off and on and then (sometimes) I'll successfully re-establish connection - only to possibly lose it again at some random point in time. Or it may work fine for an hour or more - it's hit or miss. no such problem or inconsistency with WEP enabled instead.
both laptops are running OS X 10.4.8. Of course only 802.11b on the Pismo, but results don't change on the MBP whether b, mixed b/g or only g.
The Airport Express is set up as a closed network, it's running firmware v6.3 (though I also reinstalled v6.1 but no change). I've tried many of the various other ideas for fixes - deleted Airport related keychains, etc played with various other Airport config settings - but all evidence points only to WPA as being the differentiating cause.
does this match anyone else's experience?
and more importantly, is there some fix?
thanks in advance for your feedback or suggestions

Hi!
Used to have same problems. But not anymore.
Here's what I did. I have a DLINK 624 router. not the same model but this could help you, I guess
1) Disable Super G mode into router.
2) Choose a 62 character key with a $ in front of it. (go https://www.grc.com/passwords.htm) and use wpa2.
3) Uncheck the Robutesse Interference (sorry, i am french) in the airport menu.
4) Change the advanced performance settings from auto to 11 (Tx rate) into router.
5) Whent into keychains and only kept the one for the active wi-fi. Since I tried almost verything, there where a lot!
Since I did that, no more lost connection for a day now!
Now I am not saying that this is the ultimate fix....but It worked for me.
BTW, did not do the SMC and EFI upgrade, still a little scared after what I read in the forums...I bought my mac book pro last week...how come it did not came with all the upgrade done??!! bizarre.
Good luck!

Airport issue after update - Status grey / Connection OK - Solved

Hello All,
Just wanted to share an issue I had that was driving me nuts, and then the final solution.
Ever since the recent airport extreme update, my airport status has been broken. The menubar icon has shown up as grey / no signal, and when I click on it, the only option I have is to 'turn airport on' which when selected does nothing.
In spite of this, though, my airport connection for my preferred network is working fine - I just can't select a new network off the list (there is no list, even in internet connect)
This has been a problem since the airport extreme update. Nothing I did seemed to help. Finally, I called apple and spent 45 minutes on the phone with them, doing the obligatory pram resets and power management resets, etc. Nothing seemed to help. We found a way to enter networks manually (go to system prefs / network / airport and add your network there) but the status problem was still there.
After I got off the phone, I went to the apple support page and found the airport extreme software update and downloaded it manually and installed it.
Manually Downloading and Installing the airport extreme update again solved the problem.
I don't know why the software-update version didn't quite work, but installing the update from the website did solve the gray / broken airport status menubar problem.
Just thought I'd share that with everyone, as it's been driving me nuts for the better part of a week.
Cheers!

I would like to confirm that update worked for me too. Actually, I didn't need to do it manually like some of you did. It worked straight away after automatic software update.
My problem was occasional inability to connect to my wireless router. The problem would have been solved by SSID change manually on the router and reconnection.
After the latest update, everything is working flawlessly.
I have (not so known) OZENDA router and didn't have Parallels installed.

Very odd Airport issue airport has a mind of its own...

Ok so hopefully I have gotten your attention. As of 3 days ago my Macbook Pro (which has always connected to the internet through my Airport Extreme with the signal boosted by an Airport Express) so I am online reading email when I attempt to open a new page and my internet dies. I look at my other computer (Macbook not pro) sitting next to me and it is connected to the network just fine. So I go to connect to the internet again and I can see my network and yet every time I try to connect I get a message saying "error couldnt connect" or something similar to that. Then I went to make sure my settings werent changed and they weren't. So I ran a diagnostic to make sure that nothing was wrong settings-wise. And when I get to the step where I need to choose the network I want to connect to it asks for my password (been using same one for years) and I input it and it tells me the password is incorrect. Then I try it again, and again im told the password is incorrect, no caps are on im spelling it right, basically I am faultless. Then after a number of restarts and frustrated hours, out of nowhere it connects again.
So then two nights ago I am online I pick up my laptop from my bed and walk to the room next door and start to use my computer in the next room to show a friend something. I walk back into my room with the laptop and 8 minutes later the same internet issue occurs again. I try everything, the password isnt accepted anymore and then a couple of hours later it works.
So then tonight I am writing a paper and the same stupid thing happens again. This time after 3 restarts I get back online but it is still very very frustrating and I have no clue what is wrong
If anyone has any advice PLEASE im all ears

Welcome to the discussions!
The fact that things improved a bit with Interference Robustness is probably a major clue that you are experiencing wireless interference issues at your new location.
The most common cause of interference problems in a home are cordless phones, which typically operate at the same frequency as wireless networks. You need to power off the phones and their base stations / cradles for a few hours to see if you notice any improvement in the performance of your wireless network. If you do, you need to try different positions for the phones.
Please post back on your findings to take the next possible steps in identifying the probable interference issue there.

Imac freezes during start-up. Seems to be caused by Airport issue.

My Imac freezes during startup. I have tried starting it in safe mode without any luck. After the initial start sequence when it gets to this point: Airport linkup en1, the computer starts writing the same line endlessly: com.apple.launch [1] (com.apple.mDNSRsponder [2710]): posix_spawnp (“/usr/sbin/mDNSResponder”,...): No such file or directory
I am not a technician and new to Macs too. I have tried almost everything in the supportfile about freeze issues. I am not able to start the Mac in safe mode. I have repaired the disk. I have tried reinstalling the software, but this fails too.
Did a couple of changes on the timecapsule before it happened (creating a network and new security settings and backup settings) and installed Photoshop Elements 9 and did a lot of file restructuring. Left the computer open and came back to a blue screen. Since then I have been unable to start.
My macbook works fine with the changes. I am stuck - what to try now?
I need my files and they are luckily on the timecapsule, but i am not able to open the imac-bundle file on the macbook, why?
Thanks for helping.

did a lot of file restructuring.
In Finder>Go>enter /usr/sbin do you see mDNSResponder listed there?

C2D Display issues fixed with new Logic board. READ before this is deleted!

While searching on Google for answers regarding logic board problems, I found an interesting MacFixIt article. Unfortunately I'm not sure how many of you read it because I could only access it now through Googles cache.
From the article:
We continue to report on an issue where their MacBook Pro Core 2 Duo (Late 2006) displays flicker or suffer from appearance of horizontal distortion lines. This issue is reminiscent of a problem that plagued some iBook G4s, generally resolved by logic board replacement.
It now appears that Apple is replacing specific parts to remedy this issue, though a parts shortage problem may be causing delays. It also appears that this issue is not directly related to any defect in the display, as that is not the part being replaced in most cases. Instead, the logic board seems to be implicated.
I hope this may be of some assistance to those of you suffering screen problems.
As to this post being removed, well two of my threads regarding my logic board problems (core duo) were removed. Another thread regarding a possible delay in MBP C2D because of screen issues was removed yesterday. So read and reply quickly.

MacBook and MacBook Pro with 10.6: Wireless Airport Issues with Cisco

Long Story but please bear with me:
Loaded SL on my daughters MacBook and my MacBook Pro. Internet worked flawlessly at our house (WEP encrypted) and on other public wifi. When my daughter went back to her sorority house at college 24 hours later, she could not access the internet using the sorority house network (Cisco Aironet 1800 router and Cisco Airo Access Points).
Her Airport on the MacBook appeared connected at full strength yet no internet. Two calls to Apple support (they were very nice) did not help. All the following were tried:
1. Reset PRAM
2. Deleted Airport and Safari plists
3. Edited locations
4. Removed Battery
5. Others I cannot now remember
Still no net. However, she could 'pirate' and hop on line with other identified public wifi adjacent to the sorority house. I drove to the sorority house today and tried to get on the network wirelessly using my MacBook Pro with SL. Same identical results to hers. Another MacBook without SL works great and gets right on the network.
Is this some SL influenced issue with the Airport card and the Cisco system? Weird that both of our laptops work great with several other wifi networks but not the one at the sorority house.
Could much of what we all our seeing with the internet access problem lie not with issues within our software or computers but with the routers and access points not being compatible? I have very little understanding of this stuff (as you all can probably tell) but the Apple Support people acted like it was a old firmware issue with Cisco and not with SL. Not actually what I wanted to hear.
Any ideas or suggestions?

Your description there, particularly the last part, sounds like my problem. At home, we connect using Airport and ADSL which was OK, once SL had sorted out passwords.
At my office, where there are two wifi systems, I could not get on either, although did have IP numbers on both. The link to the outside world is via a proxy which uses a PAC file. Network Diagnostics reported each time (whatever I did) that the link to the server was OK, but the Internet was not.
I created a new Location with identical settings (typing them in and not copying) and the only visible difference is that the new location has no DNS numbers -- I had not noticed that before. The moment I pressed, Apply, the computer was online.
I was guessing that there was a conflict in a .plist file somewhere; but now I wonder if DNS might have been the reason (the DNS number usually used is the one from the router itself).

Macbook/Airport issues

Hello..
Some months ago I bought an Airport Express (now running 7.6.4) to extend the WIFI from an Zyxel modem.
It has worked without a problem for months. Now however I am having issues with just one of the Macbooks (now running OS X 10.8.5) in the house.
First of all, Safari is loading VERY slowly and are sometimes loading pages partially whereas other times not loading them at all saying: "Safari cannot open page" (this is my translation from danish). Second of all, neither Mail or App Store seems to be online. Mail is not loading any new mails and App Store gives me the message: "Cannot make connection to App Store Internet connection required" (again my translation from danish - it might not be exact). Transmission has 25 finished torrents in queue and is not uploading, so I would think that this application does not really have internet either. Actually it seems as though the computer is offline, although Safari does load a page from time to time which I think is sort of weird.
When connecting to the Airport using an ethernet cable everything runs smoothly! The problem is only there when using WIFI.
My girlfriends Macbook is running 10.6.8 without any of the issues Im having. We also have two Apple TVs working without issue.
I have updated my Mac and the Airport and I have tried to disable DNS Prefething, none of which have solved my issues.
Please help!
Thanks in advance

Back up all data before making any changes.
Step 1
Take all the applicable steps in this support article. If you're running OS X 10.8.4 or later, run Wireless Diagnostics and take the remedial steps suggested in the summary that appears, if any. The program also generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 2
Run Software Update and install all available updates for OS X or your computer's firmware.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. Continue if you find that Wi-Fi is faster with Bluetooth disabled.
From that same menu, select Open Bluetooth Preferences. If the box labeled Discoverable is checked, uncheck it. Click the Advanced button, and in the sheet that opens, uncheck the top three boxes, if any are checked. Click OK. Enable Bluetooth and test again.
If the application called "Bluetooth Setup Assistant" is running, quit it. Note: this is not applicable to OS X 10.9 or later.
Step 4
This step will erase some of your settings in the Network preference pane. Make a note of them before you begin, and recreate them afterwards. It may be helpful to take screenshots of the preference pane.
Triple-click the line below on this page to select it:
/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with "com.apple.airport.preferences.plist" selected. Move the selected item to the Trash. You may be prompted for your administrator password. Recreate your settings for Wi-Fi in the Network preference pane.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
Step 5
Reset the System Management Controller.
Step 6
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

apple told me it's probably interference from something like a phone or etc... but i've moved everything away, and nothing helps. unless someone is aiming a microwave at my room, i think there's something screwed up with my mac. it's not the router (airport express base station, latest firmware) - we have 3 other macs that use it with no problem at all.
