IMac Airport Issue

I have an Intel iMac running 10.5.8 & the airport hasn't worked adequately in a long time. My MacBook Pro can sit next to it & get a full signal & the iMac signal comes & goes. Anyone know why?

I have exactly the same problem on my spankin new iMac 21.5in. It has Snow Leopard 10.6.8 and drops Airport randomly several times a day. Very annoying. Can fix it by restarting airport but that gets friggin tiring after the first few times!!
Talked to AppleCare and they seem clueless at the time, what gives? They have had me delete configurations and create new users and what not and it still does not work.

24" iMac Airport & Dock Problem

I received my 24" iMac 2 days ago: beautiful machine! I am having trouble with various things, though, and I don't know if these are problems with hardware, software or both. I don't want to spend a lot of time installing programs and getting the computer set up if it is defective and will need to be replaced.
First of all, the computer will connect with my 1st generation AirPort Base Station manually, but it won't reconnect automatically after sleep or restart. I have 3 Apple laptops and a G5 iMac that work fine with this Airport, so I think this is a problem with my new machine.
The computer was dodgy from the start, possibly due to poor performance of my wireless mouse. I was convinced that the data I'd transferred from an old machine was causing my problems, so I erased the HD and reinstalled the system and base software, then did a software update to get everything up to date. I also reset the PRAM and repaired permissions (does that ever really help?). That is when I discovered the mouse issue so I'm not sure if the early problems I had were all due to the mouse's inconsistent performance.
I connected to the wireless network with the initial setup of the machine after I reinstalled the system. Since then I've successfully connected through the Airport icon menu as well as Internet Connect and the troubleshooter program, but the connection lasts only until the next sleep or shutdown. I have to type in the name of the network and the password each time.
I'm running a closed network. I've entered the Airport ID to the Airport base station and as I said, it will connect manually without problems. The Network is set to join preferred networks by default and my network "Home Wireless" is the only preferred network that shows up in the list.
Next, the dock intermittently won't show up when I drag the cursor to the bottom of the screen. It displays all the time if I unclick the "Automatically hide and show the Dock" button, but I like the dock hidden when I'm not using it. This behavior is different from any of my 6 other Macs. I have plugged in a USB mouse and the dock seems to be working more reliably with it, though there have been some episodes of the dock not appearing even when I'm using the USB mouse when the wireless mouse is also connected. Could the wireless mouse be causing this problem with the dock?
The wireless mighty mouse's performance IS very spotty. Pushing the scroll button won't reliably call up the Dashboard, and the side buttons seem to either activate the Expose function too easily or not at all. In fact, there have been times when each of the buttons haven't worked properly.
Thanks for any advice. I'm hoping that replacing the wireless mouse will fix the mouse and dock problem and that the airport issue will be a software problem that will be fixed soon. I've read several others' posts relating to networking problems with the current generation if intel macs. I don't think that these are all operator dependent.

I unclicked "create a closed network" and now
everything seems to work on wake from sleep and on
restart. Is that the same as broadcasting the SSID?
Yes
If anyone else is following in my footsteps, I also
changed the security from 40 to 128 bit WEP at the
same time because if WEP is a useless scheme as I've
read, I want it to be the best darn useless scheme
it can!
Though 128bit WEP can be hacked, it takes a lot more traffic to find the key then using 40bit WEP.
Thanks iFelix. Any idea how much chance there is for
someone hacking my WEP in a residential neighborhood?
Depends on who your neighbours are...
To be honest if you lived in an apartment block I would argue you were more at risk than if you live in a detached property with only a couple of neighbours.
Should I update my wireless system? I'm happy with
the performance of the AirPort otherwise,
If you're happy and it's working, keep it as it is.
but I'm
disappointed that they don't allow an upgrade to a
more secure system and also VERY disappointed that I
can't at least create a working closed network with
my new Apple iMac.
The thing is putting your Airport base station in a brown paper bag adds as much security as creating a closed network does.
A wireless network is still broadcasting and therefore detectable regardless of whether you broadcast the SSID (closed network) or not.
A determined hacker (one who can hack 128bit WEP) will not be put off by a closed network.
As for casual users, well the 128bit WEP will stop them.
Unfortunately "Closed" networks, MAC access control lists, and reduction in transmission power are all more "feel good" security rather than real security. All these various approaches are dated and mistakenly lead to overconfidence.
WPA is your friend if you value wireless security, but that will only be possible if you upgrade your wireless router.
It could be for a variety of reasons why your Mac and original Airport don't like working with a closed network, however it does seem to happen more often when using hardware from different manufacturers.
The reason why your previous Mac didn't have this issue is that it used a different wireless chipset to your new Mac, which is the main reason for the issue you are having now.

Intel iMac airport connection problems

Hello,
My new intel iMac connected up to my 802.11g 3come wireless modem/router fine, the strength in excellent (always full or nearly full) but the connection is very very intermittent.
It will only work for a minute or so but then the internet will go down on the machine for about 30 seconds, then come back on.
The network file sharing also goes down. Other Windows PCs on the network do not have this problem.
I have tried the following, none has had any effect:
[*]Turning off all other network PCs
[*]Disabling all encryption on the router
[*]Using different browsers
[*]Calling Apple support - first they asked me to adjust some networking options, we also setup a new network connection. They then sent me a replacement iMac - it's exactly the same
The firmware is up-to-date on the router.
I am aware there are similar posts in the forum, but other people's problems seem to be to do with their speed. None of the solutions have helped.
Any suggestions?
Thanks for your support.
Davood

I wasted hours and hours trying to figure out a similar problem with my machine. Apple Support denied all knowledge of known issues, but then I came across a discussion titled "Will Apple react to the Airport problem with the new iMac (Intel C2D)?" - you will find it on the 5th page (at the moment) of these topics.
It is one of the largest threads I have seen in these forums (113 replies). I tried to add an update, but curiously the thread is now locked - Apple are obviously keen to censor further discussion on the subject.
Apple do now acknowledge that there is a problem with Airport and the Intel-based Macs. They are supposedly working on a fix, but when that will come is not clear.
I would urge everyone with Airport issues to pester Apple Support until they solve this problem.

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?

Hi, I have imac mac os 10.6.7, I can't access to internet with my ipod touch using my imac airport...what's wrong? my ipod tells me is connected and airport is active...so? what should I do?

Hi,
I have imac mac os 10.6.7, I can't access to internet with my ipod touch using my imac airport...what's wrong? my ipod tells me is connected and airport is active...so? what should I do?

right, figured it out. had to put it in disk mode, then reconnect, then it was recognized, then i restored and put everything back onto it. hope this helps anyone else who has a similar problem

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.

IMac, Airport Express, Roku-2 player. Help!

Hello,
Let me start by saying I don't know anything about Networking at all.
I have an iMac with Arport Express built in.
I have a Roku-2 XS player I want to stream video from the internet in another room where the Roku-2 will be.
I have an Apple Airport Express base station.
I have a Motorola SB6120 SURFboard DOCSIS 3.0 eXtreme Broadband Cable Modem.
How can I hook all this together.
Do I connect the base station to my Modem and then stream from the base station/modem combo to my iMac via it's built in airport and also out to my Roku-2 player?
Or do I set up the Apple Express base next to the Roku-2 in anpother room and then streem from my iMac Airport Exress to the base station and then into the Roku (either wirelss or wired)?
Thanks in advance.

Thanks.
The Roku is like any other wireless device I guess and it should be very simple to set up but it's just that I know absolutely nothing about networking and wireless devices other than my daughters iPad and her Touch.   Those two devices connet to the internet through my iMac's airport Exptreme card.    Since I have no experience with Wi-Fi other than Apples iPad and Touch I always thaought my Mac's built in Aiport Exptreme was some sort of router than could access non apple devices should I ever get one.
I have been told I nned some sort of wireless router to do the trick.   I grabbed the Apple Airport Express in the hopes that this would do the trick but I have no ide where to start. It seems all the info I've read seems to start with the basic premise that you know some basics about Wirless.
So I have the stuff I've listed above but I'm not sure of the configuration. I do not understand making a new network. I'm totally a newb.

IMac Freezing Issue -Need Confirmation...

Hey all,
I need confirmation on whether or not zapping the PRAM seems to stop the iMac freezing issue. I have had 3 freezes within 10 minutes. I restarted after my last preparation to installing Leopard and the screen saver kicked in, which is the 'Cosmos' slide show and the graphics froze up. Screen went black and I left it for a couple of minutes. I came back to it, and had an image on the screen, but it was still locked up. So I restarted it. After boot up, I opened Activity monitor, and locked up again.
So I zapped the PRAM on this 3rd restart and have not locked up since. I'd bet 100 to 1 that if I were to restart, without the PRAM reset, I would crash within 5 minutes of the start up.
I really believe without a doubt these iMac reboot issues are related to specific EFI versions failing to initialize graphics correctly.
Can anyone confirm this? If your iMac crashes, does Zapping the PRAM fix it?
I'll be calling Executive relations contact and telling her the bad news.
Okay, so first off, this isn't a solution to this iMac plague, but it should prevent the freezing and NO, it does not have to do with removing the ATI drivers.
I was asked to install Leopard by Executive relations at Apple and told her that, as soon as I do, my iMac will freeze. So, I have been preparing the Leopard install and have crashed 3 times, in a row... at that point I said, Leopard is going to be a no go but I needed to use my iMac without it crashing. So, zapped the PRAM like I did before and immediately the graphic freezes went away.
So

Here is my experience, iMac 24:
I bought in JR NY 2 weeks ago. I had to use it without internet connection (so no updates) and no freezes.
Then I connected to internet and installed the available updates and start to get the freezes, even trying the PRAM reset.
I tried to remove the extra memory, change memory slot but no lucky, video artifacts (like pixels not refreshing) when moving the mouse over the dock icons then freeze.
I had no other softwares installed at all, only the OS applications.
I formatted the HD and reinstalled the Tiger and didn't accepted any update, so I could use the imac for 2 days without a single freeze, but some black screens when screen saver starts.
Since no freezes, I decided to update the OS again and after the first boot the freezes came back very fast, I could start a freeze in about 10 seconds.
I tried the PRAM reset without sucess and my machine was ready to go to a tech person.
Yesterday I updated the OS to 10.4.11 and did a PRAM reset after the update and tested the machine for 2 hours without a freeze or video artifacts, looks very stable, but I have to test it more.
You guys tried the Tiger last update ?

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.

WRT54G - Cannot access internet but iMac airport says internet connection is fine... what's wrong?

I use a WRT54G wireless router connected to Mac. All of a sudden, I became unable to access certain websites on my iMac, such as Facebook and Apple homepages. But i can access Yahoo website. I tried resetting my linksys setup but it doesnt solve the problem. When i access my iphone via wifi at home, i am also unable to go into app store, facebook app, and emails with images won't load. I also cannot link my iphone to itunes on my iMac. What happens on my computer when I surf the internet is that the page just loads halfway and stop "responding". But my imac airport says that my internet connection is fine, however my access has become very "restricted". Can anyone tell me what's happening and how to resolve it?

To resolve difficulties accessing some websites when connected to a Linksys router you should check the following.
Checking the router’s security settings
Checking your computer’s security settings
Security on the web browser is set too high
Configuring the Maximum Transmission Unit (MTU) on the router
Opening ports for secured sites

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.

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?
Try Repairing Permissions for the Volume in Disk Utility (Note: may take a long time in 10.5.8)

IMac G5 airport issue

It would seem reading the rough the iMac G5 forum that many of the G5's are having issues talking to Airports. I don't believe it is an issue with the AEX / ABS since other devices work fine. However thought I'd cross post to see if anyone can shed any light...
It (the iMac G5) will communication with either a Airport Express (6.3) or a Airport Base Station (new 802.11n 7.1.1) but after a while it just drops off the network.
I place a AEX within 3 feet of the iMac and I'm only getting a 40% signal with lots of noise, nothing has changed but just in case I've changed channels with no joy.
I was suspecting a airport card issue but I think it may well be a recent update (maybe something to do with the 802.11n enabler software for intel's - some kind of preperation patch???).
I'm pretty sure it is nothing to do with my ABS or AEX since a I have a Mac Mini, WINtel laptop, Wii, PS3 etc. all working fine to all stations.
All software is up to date.
My airpot card is:
Airport Extreme
Firmware 405.1 (3.90.34.0.p18)

The wireless card in that iMac is not a user-installable item so Apple does not provide the instructions to access or replace that card. But you can see how to get to that card by looking at these instructions from iFixit.com
