Airport doesn't auto connect to network

I have a new 21 Incg iMac with 10.6.2. I have Airport set to connect automatically to known networks. Some times it connects fine. Other times it shows no known networks found and gives me a choice of networks. In that list is the known network. When I click opn it the network password is filled in and everything. It them lets me join just fine. Why is it doing this?

Be sure to push the one network you want to the top of the list - remove any others to help that selection take priority.
System Preferences/Internet & Wireless...your existing Airport connection in the list on the left should be highlighted then hit the 'Advanced...' button - use the first tab on the left titled 'Airport' and take at look at the list of 'Preferred Networks:' - use the options as described to make changes, sort, delete, etc.

Airport doesn't automatically connect to my preferred network

I had my hard drive replaced and ever since my airport doesn't automatically connect to my wifi network. I have specified my network as my preferred network in my system preferences.
I need to re-connect to the network manually (ie: I need to select my network form the drop down list) each time I wake my computer up from sleep mode.
How do I have my airport automatically connect??

Go to System Preferences then select the Network icon.
Select the airport adaptor then click advanced
the first tab "Airport" has all your recent SSID's listed.
Select the desired network and drag it to the top of the list and check the " Remember Networks this computers has joined."
Apart from that the next best thing would be to removed all the networks from the list and add that network you wish to join to verify its configuration

MacBook no longer auto-connects to network after 10.4.8

I have a MacBook and use Airport to connect to my wireless router. It always used to auto-connect to my router upon booting up. Now that I've installed the 10.4.8 update, it no longer connects automatically. I have to click on the Airport icon on the toolbar and select my network; only then will it connect.
I have already read this article:
http://docs.info.apple.com/article.html?artnum=304482
and followed its directions, but it did not solve the problem.
(Incidentally, I do not use WPA2, just WPA Personal.)
MacBook Mac OS X (10.4.8)

From http://www.macsonly.com/ , today
not tested :
After we tested the latest Mac OS X update, v10.4.8, on our 2.33GHz 24" iMac Core 2 Duo, we added another user account for the long-term tester. But after a restart or cold start, the iMac would reconnect to our AirPort network but it would get assigned an internal IP address rather than one from our router so it would not connect to the internet.
This problem could be temporarily solved by using the AirPort menu icon to turn off and then turn back on the AirPort card. This was frustrating because the original user account on our iMac continued to connect automatically to the network and internet after a restart or sleep as did all of our other Macs upgraded to 10.4.8.
We tried everything listed by Apple in its technical support articles (e.g. Article Number 304482) and provided on other Web sites, including deleting the preferred network in the System Preferences Network pane and re-adding it. We even tried deleting every AirPort-related preference ".plist" file including the "Networkinterface.plist" as recommended on another Web site yesterday. Nothing worked.
Then we tried a variation on Apple's suggestion and it worked. Here are the steps:
Open System Preferences, select the Network pane and select AirPort in the "Show:" popup menu.
Set the "By default, join:" popup menu to "Preferred networks."
Delete the listed preferred networks using the "-" button but this time we did not add it back again with the "+" button as Apple recommends.
Set the "By default, join:" popup menu to "Automatic."
Restart.
Manually rejoin the AirPort network using the AirPort menu icon, i.e. selecting the network (or selecting "Other" and typing in the network name if hidden) and typing in the WPA (or WEP) password.
Now every time we restart our iMac, it automatically connects again to the AirPort network and gets an IP address assigned by the router so that it also connects to the internet. [Bill Fox]

Airport won't auto connect to my router, connects to the neighbors regularl

Hey,
Every time I close my computer it logs off of the internet, which bugs me. Additionally when I open the computer back up instead of auto connecting to my internet, it connects to the neighbors internet titled Lynksis.
Can anyone tell me how to resolve these problems? thanks!
Kristian

Kristian,
Rob has it mostly right, but you might not see just what he indicated. Once you see the "Airport" pane, you will see a pull-down menu in the body of the window (the "By default, join:" menu). This pull-down will read either "Automatic" or "Preferred networks." Only if it shows "Preferred networks" will you see the actual list of networks you have allowed your Mac to join. By changing the menu to read "Preferred," you can see and edit the list.
My recommendation is to get to the list, make your changes (which should amount to removing the "Linksys" network, plus any other generically-named networks you find), then change the pull-down to "Automatic." Using the options in this manner will do the most to reduce the chances of you having to adjust things manually on a regular basis.

10.4.6 FUBARed my ability to auto-connect to network at startup

So I was a space-case and updated to 10.4.6 using auto-update instead of downloading it myself... yeah, I know...
Anyway, now my G5 and my wife's iBook don't connect automatically to our secure network at startup anymore... we have to manually select our network from the airport "radar" icon dropdown list, and that's usually after a few seconds of waiting for it (or any other networks in the apartment) to show up.
It seems as if the airport software is looking for our network too soon, so it gives up, even though our network is visible on the dropdown list.
All our settings are the same as they were before the update...
Any ideas? I'll reinstall from a disc image from the previous OS version if I need to, but that's a bit of a pain. It seems as if this update messed with quite a few systems from what I've read in various forums, but no-one else has similar symptoms as we do.
Oh, and the aiport base station is at the most current firmware version.

So, Will...
Your suggestion made me dig a little deeper, and I wondered if there would be another reason that, even though our network was the only preferred network available, our macs were'nt choosing it. I selected "edit" from the preferred network window, and re-entered the password for our network, restarted, and.... it worked.
SOmething must've gotten jacked when I updated to 10.4.6
Oh well...
Hope this may help other folks with a similar situation.
Case closed.

Auto connect to network disk

Is there a way to set the network disk connected the USB port on the AIrport extream base station to auto connect on boot up? When I shut down the iMac or reboot the shared network disk has to be manually connected. Any help will be greatly appreciated.

td - thanks for the reply. i will try it when i get access to the machines again. i initially did have sharing from the Users/Shared folder, and it worked great - except if someone edited something while the library was open on another person's computer. then the database would be corrupted and would only open on the machine that just saved it (which is odd). if library is shared from this folder, will iPhoto 8.0.2 give a warning message and prevent access as the apple doc claims?
also curious - why then does apple say the sparse format is not required, but is recommended?
+From the Format menu choose read/write disk image or sparse disk image (recommended).+

Airport Express G cannot connect to network

Hello,
I have the Airport Express (G version) running the 6.3 firmware. My problem is that I cannot connect to my home network. When I use the airport express to create the wireless network, I can connect the Windows and Mac machines to it to stream iTunes and all works perfectly. When I connect it to my home network (Linksys WRT54G running dd-wrt) I cannot connect anything to it once it is configured. I set it up from the mac and all the network settings are transferred to the Airport Express. It seems to connect for a minute then the connection drops. Sometimes iTunes sees the Airport Express and it tries to connect but is unsuccessful. I cannot edit the airport settings from either machine without resetting it to factory defaults and reconfiguring.
The problem seems to be the Airport Express doesn't want to play nice with the home network. Does anybody have any suggestions?
As I am writing this I cannot remember if I have had the Airport Express working since I've installed dd-wrt. I know it worked pre dd-wrt and am hoping that isn't the issue.
Thanks in advance for any help.
Jared

Express works fine with third party routers including the WRT54G, but once you modify it you're on your own. I'd go to the dd-wrt forum and ask around.

Airport card not auto-connecting after adding WPA on router

Hello;
I recently turned on WPA security on my previoiusly unsecure router (I had been using a MAC filter) and set up a password, etc...
Two laptops connect to this, my iBook G4 (powerPC), and a Sony Vaio. The Vaio remembers the password on reboot, but the iBook keeps forgetting it, as if somewhere it has the old settings still stored away...
Everytime I reboot I have to go into system preferences, network, and do a 'diagnotistics' to get it to find it, and add the password by going through 'closed networks' (otherwise it just tells me it failed to connect and never asks for a password).
Is there some way I can get it to remember the settings across reboots?
Where are the preferences stored so I can remove them and 'start over'?

Deleting the keychain with Keychain access worked.
I still can't click on options nor see preferred networks, but now the new keychain I made is finally staying around after reboot and auto connecting me to my home network.
Thank you for the help. I did accidentally delete ALL my keychains, but that's just as well as I probably had other clutter in there as well.

Airport Extreme won't connect to network

I just replaced our old Airport Extreme with a new Airport Extreme. Now our Airport Express won't connect with our network. I've got the dreaded blinking yellow light and the Airport Express does not show up as an icon in my Aiport Utilities application. Any ideas? Thanks.

Whenever changing out networking hardware it is always a good idea to perform a complete power recycle of all of your networking gear to make sure that they are communicating properly. Once you re-established a working baseline between the new Extreme and the modem, we can assist you with the Express if you still have issues getting it to connect.

Since the last update my HTC DNA doesn't auto-connect with SYNC anymore. I have tried unpairing and repairing and restarting my phone. I can still connect manually but I cannot locate a setting to turn on the auto-connect.

How do I enable the auto-connect to SYNC in my Ford Escape again?

Hello Me29.
I love the convenience of using Bluetooth in my car, and I want to make sure you don't miss out. Please follow the steps in this link to troubleshoot the SYNC feature: http://ford.to/1lfZOrG

AirPort does not auto-connect to existing network after waking from sleep

...but I can easily connect it manually. I read the FAQ on this subject and followed the resetting steps in system preferences/network (the procedure was specific for Intel iMacs-but I did it anyway)
It did not help. The flaw just occurred a couple of days ago, after a year of flawless operation Please help.

Solved! I trashed the internet connect preference in the library, and it worked!

AirPort won't auto connect after resetting admin password

The other day I reset my admin password using the install disk and now AirPort won't log on automatically when I start my laptop. Has this happened to any one else? I have tried going through the network preferences, internet connect, and tried a couple of other things and the problem hasn't been fixed.

Try the following, in order, until (hopefully) resolved:
1a. Delete Preferred Network(s)
System Preferences > Network > AirPort > Advanced > AirPort tab
Under "Preferred Networks," delete the network(s) you regularly use from the list.
1b. Delete AirPort Keychain Entries
Launch the "Keychain Access" application located in Applications/Utilties.
Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
1c. Add Preferred Network(s)
System Preferences > Network > AirPort > Advanced > AirPort tab
Add the preferred network(s) using the "+" button.
Restart or log out then back in.
2. Move System Configuration Files
(Note: You will have to reestablish your network connections settings.)
Go to /Library/Preferences
Move the SystemConfiguration folder to the desktop.
Restart your Mac. (Note: OS X will rebuild the files that are now sitting on your desktop. If this doesn't resolve the issue, you can move the folder back to it's original location.)

AirPort utility suddenly not connecting to network properly

It's really frustrating, because I've tried a number of things and I still can't get it to work. Basically, I had wireless internet connection working just fine, the router (Linksys, if it matters) just a few rooms down like it always is. I left my MacBook Pro on for a while and when I checked back on it a few hours later, the internet was no longer available.
Every other computer in my house is connected to the network fine, so I know it's not the router or my internet connection. Every time I select my network using the AirPort utility drop-down menu at the top right of my screen, it prompts for my network key, but every time I click on connect it just says "connection failed", and when I open up the actual Utility it just prompts me to rescan a bunch of times, stating that no apple devices were found.
It doesn't make any sense to me, expecially sionce I've had absolutely no problems for the almost two years I've owned my MBP. I've tried restarting my computer and my router but to no avail. It just suddenly stopped working last night and I'd really like to get it working again, any help I can get here would be deeply appreciated!

That has happened to me before. I think there is an airport utility that has been released recently, install that and see if it works.
Airport is weird. Try to connect your laptop and hardwire it to the router. Shutdown your MBP, turn on, and see if you get a signal.
Uninstall airport and re-install and see if you can aquire a signal. If not, there is a possibility that something with your router failed.

MacBook Pro airport doesn't choose 5 GHz network when waking from sleep

Hi,
I recently set up a Time Capsule [TC] 802.11n (4th Gen) as my airport base station catering for my MacBook Pro [MBP], iPad (1st Gen), iPod (3rd Gen) and BlackBerry 9900. I have it set up in dual-band mode (2.4/5 GHz) with the same SSID, mainly hoping to take advantage of the increased speed of the 5GHz band during Time Machine backups - I get a Transmit Rate of 300 Mbit/s when connected at 5 GHz and 145 MBit/s at 2.4 GHz. Aside from that I don't really care which it chooses to be honest - my internet connection is only 12 Mbit/s. When I start up my MBP from a full shut down within an 'appropriate' distance from the TC, AirPort automatically selects the 5 GHz band and falls back to 2.4 GHz if I stray too far.
The problem arises when I wake my MBP from a sleep (which is pretty much always having closed the lid each time I'm done using it) and AirPort ALWAYS selects the 2.4 GHz band and will never change to the 5 GHz band unless I fully disconnect from the network and then reconnect.
The iPad and BlackBerry both switch happily between the two bands as I move around the house, opting for the 5 GHz when possible and always without intervention so the set-up obviously works.
I think it's a problem in Snow Leopard having read problems around the internet from users who have upgraded from Leopard to SL, most of whom seem to do what I'm thinking, i.e. setting up a different name for the 5 GHz network and putting it higher in the priority list that the 2.4 GHz one, however the solution isn't ideal/elegant and certainly not how it's supposed to work, but I've yet to find a definitive solution from Apple anywhere.
Anyone else having this problem? Anyone found a solution? Anyone heard anything from Apple?
Thanks!

Yes. I'm having a very similar problem. I don't have TC, but I have a netgear wndr4000. I'm always bring my MBP out of sleep and having to manually select the 5GHz band. Even when I know it should. I have different SSID's on each band, and I have tried setting the priority order, but that has another set of problems. When I get a little farther away, it will hook to the 5GHz band at 54Mb, but the 2.4GHz will be at 130Mb at the same distance. I thought it would make some type of smart choice about it.
I had been thinking about moving to a Airport Extreme because I've been told by others that their machines make the correct choice with the SSIDs set the same.
I too am on Snow Leopard, but I'll be upgrading soon.

Original airport card mysteriously stopped connecting to network

i have a powermac G4 tower and have been using the original airport card for about four months. Just recently it stopped connecting to the network at all. the bars are all gray on the menu bar and when i try to connect to any network in the drop down menu the popup window just says "there was an error connecting to the specified network" when I go to network diagnostics and try to connect it asks for a WEP pasword even though none of the networks require a password and network security is set to none in system preferences for the network. I've been able to get a connection back a couple times but it was only by restarting my computer and that hasn't worked for a couple days. Is my airport card broken or is there something wrong with the operating system? I've also talked to the tech support people for the wireless network I'm using and they had no clue how to help me.

I had trouble getting my Airport card online for the longest time. Finally, I ditched the Linksys wireless router I was trying to use, and switched to a D-Link. I still don't always get full signal, but I can get online 95% of the time.
Have no idea why it worked, but it definitely works better than the Linksys.
