My Airport connection drops whenever the Mac sleeps or reboots

My iBook on the same network doesn't do this.
I guess it's a settingI'venot got right, rather than a fault as such.
Any ideas?
Thanks

See if you can find a solution in KB 304482, Mac OS X 10.4.8: AirPort does not auto-connect to existing networks after restart or wake from sleep.

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.

Airport Connection Dropping Off

Has anyone else had trouble with their Airport connection dropping off all of the sudden during a long download or transfering files across the network? If this is a common problem...I hope Apple is working on it.

I am getting the same thing. After starting a transfer of file, after awhile, it will state the wireless network has been change or comprimised (excuse my spelling) and the airport will be disable and enable in a minute. Then the finder stops responding, I cannot force quit out it and must restart the computer.

Airport connection drops under load.

Hello Community!
I have some serious Airport connection woes - whenever I heavily use the airport connection it seems to drop out every now and then. The intervals have no visible pattern, but the dropouts are directly linked to the amount of traffic going trough the Airport card.
The dropping is quickly and the Airport connection icon goes from the full 5 bars to greyed out and back. This happens at an increasing rate when it has happend for the first time after an restart.
Here's a screencast I took to illustrate the problem: [www.verpeiltaber.net/airport.mov] (Quicktime, 1.30MB)
It also drops out (invisibly) when I Skype-Out, which is extremely annoying as I pay money for that and then the other side cannot hear me anymore after such a dropout. Strangely it never kills the entire call tough. It never happens when the computer is tethered to a LAN-Cable.
I have reinstalled Leopard from scratch just two weeks ago. I upgraded from Tiger before and had the problems with that version of the Leopard install aswell. Tiger didn't exhibit the problems - which leads me to believe that this is a software issue.
The Router is a D-Link 524 with the newest aviable firmware, and has been resetted multiple times. Other computers using the same WLAN work without any hitch.
This issue has popped up in my office WLAN, which uses a Lucent Router, aswell.
I'm pulling my hairs out here - help me please!
Edit: All the latest updates are installed, like the recent Time Machine & Airport update. No third party extensions or mods are installed. The issue is operating-system - wide.

I have been having the same problem since upgrading to 10.5.2 and it's driving me nuts! Momentary disconnections every 10-15 minutes making messenger, iChat, etc. completely useless.
I purchased a 15" macbook pro for my partner 2 weeks ago - it's having the exact same issues. I'm thinking of returning the machine as I've tried everything. I have no problems with any other machine connected to my router.

I would like to set up a homegroup with a new Macbook Pro and 2 Windows PCs. The PCs are wired to an Airport Time Machine and the Mac is wireless. All computers have internet through the Airport Time Machine.

A barcode scanner that was connected directly to the Mac's USB port stopped working as the "USB had too much power drawn", even though it has worked for over a year in that port. WHen we plugged it into the port on the keyboard, the device works. Why?

A barcode scanner that was connected directly to the Mac's USB port stopped working as the "USB had too much power drawn", even though it has worked for over a year in that port. When we plugged it into the port on the keyboard, the device works. Why? Obviously the device is operational. Could the USB port have burned out from having too much power drawn? If so, is it reparable?

It can't draw "too much" power, it can only draw as much as the USB port is able to provide and no more. IIRC, the keyboard port has a lower power output than the iMac's port.
That being said, yea, it's possible that the port has failed and it can be replaced or if another port works you can use that one. Although if it is still under warranty or covered by Apple Care, then I would take it to an Apple Store or service provider to get the port repaired.

Macbook airport connection drops and locks my computer

So... I think my problem tops them all. Ive done alot of searching and ive found no topic relative to mine.
- My intel macbook has an airport extreme that can succesfully connect to my schools network or my girlfriends network or my network at home. However...
Many times a day... as soon as i make my connection active by going on a web browser.
My Airport drops connection and locks my computer... only the mouse is avaliable, but
anything else i try to click.. i end up with the spinning beach ball. Only solution i can find
thus far is to force shutdown my computer and restart... Now i cant do a PRAM reset or
start up in safe mode. I dont know how to solve this...
Can anyone help me with this? It is incredibly annoying as i have to force shutdown my computer over 6 times a day which is... bad ... for my computer. More bad clusters.
Thanks much ... G

My problem is a variation on yours.
I don't lose the airport connection at all. I can connect to my Airport Extreme base station and surf the Internet without a any hassle. I can see the other computers connected to said AEBS. Network drives are mountable.
HOWEVER, as soon as I start to transfer a file or folder from or to a mounted network drive, the transfer hangs. The only solution is to power-off Airport to get the Mac to acknowledge losing connection to the network drive. Otherwise I would continue to stare enlessly at a frozen progress bar.
Hopefully 10.5.2 will address the issue.

MacBook Pro Airport connection drops out

I have a new and really cool MBP.
I have a 2 year old Airport Express connected to a Motorola Cable Modem creating my wireless home net.
I also have a 2 years old iBook G4 with no problem connecting to the airport.
My new MBP has no problem too when is connected to the AC. BUT when I run my MBP from the battery, the connection drops out randomly.
It's annoying and I cannot find any helpfull support or working solution at Apple.com nor at the other similar thread on this forum. I've tried some proposed solutions. But none worked more than some minutes (which mean that actually they didn't work).
I have some questions about all this:
1) Anybody knows if this is a Hardware or a Software issue?
2) Apple officially said anything about this problem?
3) Can I use my purchase warranty in order to demmand a replacement?
4) Is there any official or unofficial solution that really works?
Please, help. I think it's very stupid to have a nice and really expensive laptop without real wireless capability,
Who want a wireless connection if you aren't able to use it when you are not connected to the AC????
If I was running Vista on Dell or HP laptop I would understand. But on a Mac???
COME ON APPLE!!!!!
This is the 2nd BIG problem I am facing with my new MBP since I bought it on July. I am frustrated and tired. First I couldn't use Motion 3 for like a month because of a bad update. Now I realize the wireless capability is crap.
I have the feeling that the older Apple Computers are better... at least they work!

I had the same problem on my MacBook Pro for the last month or so after "updating" to 10.4.10. Yesterday I tried Loki's fix but couldn't connect at all after that. So I did an archive/install of 10.4.9 and it works better than ever before. I get full signal and it is a lot snappier and faster. The problem is likely in the 10.4.10 update, hopefully Apple will get that fixed in 10.4.11

Since downloading Mtn.Lion my epson printer doesn't work correctly & the entire system seems to be slower plus my iMac now disconnects from my wifi every time the mac sleeps. Can anyone help me with these issues?

I am having problems with my Imac (approx 1 yr old) every since I downloaded (from the App.Store) Mountain Lion. I am a working mom with 3 toddlers.....I have very little time to work on the computer which I primarily use for photograhpy needs. I am not computer savvy enough to figure out how to "fix" the new issues/problems and am frustrated. I am hoping someone can help me........
Issues just since downloading Mountain Lion:
1) My Epson R2400 printer is not printing properly. It wouldnt print at all from CS5 the first 2 days. Then just started printing. The prints aren't nearly as good as they used to be. I just installed Photoshop Elements 10 and have been able to print but the prints are just awful. I printed a test page and it was perfect. I've triple checked the settings in the print dialogue box to ensure the correct paper is chosen, etc. I've never let the printer manage the color before but it is the only option that gives a mediocre print at best.
     I've gone to Epson.com.   It says to update driver through Apple for Mtn. Lion. According to my computer I have no updates. Printer is connected via USB. Changed the ports, turned printer on & off. Emailed epson & they said to reset the print queue, which I did. Restarted the IMac Still no luck. (The error message I got when trying to print from CS5 is "filter failed." But, as stated before it just started printing today as I was typing this.
      I print out pics quite a bit and it seems the only time I have ever had problems is when I upgraded the OSX system. Why is that?? When I upgraded to 10.7 is when I first realized my print quality went down.
2) Now every time I "wake" up my computer it has become offline and has to go through the steps to reconnect to my wifi. Never did that before Mtn.Lion. I purchased the Airport Extreme Dec 2011. My computer was always connected before the update. Now I have to scroll down & pick my network & wait for it to connect before proceeding.   I double checked preferences and it is set up to check for updates automatically. What is that about??
3) It just seems that my system overall is slower. I love my mac but I am frustrated because I don't have the free time needed to do all this problem solving. I just need it to work properly when I have a few minutes to work on a picture. I imagine there are other issues, but these are the only 2 areas I've focused on since the upgrade.
I've read different views/feedback on Mtn Lion but haven't come across the printer issue or the wifi connection issue.
Can anyone direct me towards a solution? I really appreciate it!

I just figured out the print quality issue for my wife with her new iMac and new printer.
She replaced both at once and she couldn't understand why her Artisan 730 was lower quality then her Epson R280 when they had the same specs.
Turns out the newer printer had the option to connect via wifi which we used during setup.
The driver options are completely different depending on how you connect.
Once I connected via USB the correct options were available and the print quality was better.
Looking at the R2400 it dies not have wifi, but while researching the problem for my wife someone esle was having an issue updating to the latest printer driver.
If you go into the print utility from the Printer and Scanner system preference and under the general tab you should have driver 5.5.
One user had to delete the old printer driver before Software Update loaded the newer printer driver.

On my MacBook Pro (w Snow Leopard) I always had to reconnect my wifi at home when it woke up. I upgraded my router from an old Netgear to a newer N D-Link and stopped having to do that.
I would be surprised you would have that problem with an Airport Extreme, you might check to see if there is a firmware update for it.

I Lose Internet connection each time my Mac Sleeps

I have an iMac 21" late 2009 model.
Since I installed Lion, every time my Mac "nods" after leaving it a bit, after waking up it will take about a minute for the internet connection (dsl ethernet) to come back. It's frustrating, I turn on my mac to browse the web, I open Safari but then I have to sit there waiting for the internet connection to come back.
Something is wrong and it's annoying..

If you had mountain lion, you could've used a feature called power nap. It keeps networking on even when the mac is asleep.
On other OS, I guess its bound to disconnect all networks when it goes to sleep You can try an app called Caffeine that doesn't let it go to sleep.

Airport looses AX when the MBP sleeps.

I had problems maintaining my computer's connection with my AX back in Novemer & December. Enough hints and enough fumbling around and I got a constant connection.
Then yesterday I changed the identity and password of my AX. Now anytime my computer sleeps, when it awakes Airport has lost the connection. My AX is set for WPA2/personnel and cloaked identity.
Coincidentally, I updated to the latest version of the Airport Utility. Connection?
Any ideas? Others with similar problems?

More information:
If I turn Airport off then back on, Airport connects to my AX.
I checked my Keychain. There was an entry for my old ID which I deleted. Made no difference.

Airport Connection 'Drops' on Mac Pro Running 10.5.6

I have read the many incidents on this forum of Leopard problems / connection inconsistencies via Airport & a a wireless router.
It has become almost impossible to sort the wheat out from the chaff with regards to solutions for this problem.
I have tried the following 'solutions':
Deleting potentially conflicting / out of date preferences,
Clearing / deleting caches using Onyx,
Repairing Permissions,
Creating a new 'location' in Network Preferences,
Using Open DNS service
The connection still drops at least once every hour as detailed in my Bug Report (sent via online form) below:
Any updates on this? Is there a definitive solution, yet?
I don't have the option to rollback the operating system with Time Machine... my Time Machine drive failed just before this. Fortunately, all of my documents are backed up elsewhere.
If you need more info, feel free to ask.
Thank you!
Bug Report below:
Hello,
I have a Mac Pro (profile copied below).
I'm running Leopard 10.5.6
This set-up connects to the internet via a Sky (UK) ADSL wi-fi router (only a matter of months old).
Since upgrading to 10.5.6 I have been experiencing drops in my internet connection every 5 minutes - 1 hour.
Drops = the airport signal strength signal drops from 5 to 1 or 2 bars [but doesn't drop to no bars] and the connection 'fails' -- i.e. downloads stop, pages fail to load, I can't access e-mail accounts.
The connection does reinstate itself, but is much more unstable & from that moment drops much more frequently.
This wasn't happening until I upgraded to 10.5.6
I have a MacBook Pro (one of the original models) and that experiences no connection problems at all, connecting to the same router (the MacBook Pro is also running 10.5.6)
This is incredibly frustrating.
It has rendered my £2500 system useless for work.
I need a solution, badly.
On your own support forums, it appears that there are a number of people suffering similar problems.
Will you please offer a solution / a fix ASAP.
If you need any more information, please do not hesitate to contact me.
Many thanks.

I had a similar problem which I've fixed!
I have four machines here which can connect to my Netgear DG834N via Aiport. (I say can because they normally connect via ethernet.) My MacBook Pro always used to be fine when connected wirelessly but recently, not aware of any changes I've made, it connects for about 10 seconds then disconnects. All other machines are fine and hold the connection.
This is what I tried before finding my solution:
1) Deleted all references to the network in the keychain and remade them.
2) Created another user to try
3) Changed channels on the router even though I can't see any neighbour's networks.
4) Made sure computer and router were up to date with firmware/software.
I'm assuming that it has to be a computer problem as the PowerMac, iMac and iPod Touch have no issues at all. However, the cure was in the router.
I run with SSID broadcast turned off, WPA2 encryption and MAC address filtering. Allowing broadcast of the SSID cures my problem. Turn it off and the computer connects then drops it ten seconds later. Turn broadcast on and it maintains the connection. I've tried it all afternoon, leaving it connected for about 30 minutes at a time before turning SSID broadcast off again. Works every time! Broadcast SSID - fine, no broadcast - drops after ten seconds.
Now, if only I knew why! And why only the laptop?

Airport connection drops about once a day..

is the problem in my macbook or in my airport?? when i go to look at the airport, the green light is still on. help would be appreciated.

Hola -
If you go to your System Preferences/Network/Airport and check the box "Show Airport status in menu bar" you'll be able to see the strength of the signal in your top menu. 4 bars will equal a strong signal. Monitor this throughout the day ...if it's working fine for most of the time then I'd suspect the wireless router as the problem. Also, if the signal is very weak (1-2 bars) then you may indeed lose your connections at times.

P2P connection drop issue with MAC 10.5 Leopard

I have P2P application which connects to FMS Server hosting with influxis.com using RTMFP protocol . The application works just fine with all other OS except older MAC 10.5 Leopard with flash player 10.3 installed.
The problem is that p2p chat, audio and video does not transmit and connection is dropped after around 50 seconds. Its same with different Computers with above mentioned OS and configuration.

It happening only on MAC 10.5 with flash player 10.3 but happens never on newer MAC or Windows PC with any browser or flash player . So it seems a old MAC specific bug.
The same issue occurs with the (Cirrus sample application ) by adobe using rtmfp at this link
