Airport to gateway network disappears

I have two networks set up on my G5 iMac, one for iTunes (connected to an AEX), and another one connected to my Qwest gateway for internet access.
The internet network keeps disappearing. I have to go to the Airport menu and do a "Join other network". I've also noticed that after the network shows up in the menu, it doesn't have a lock symbol next to it like the iTunes network. And when I went to the Network preference pane this morning, the padlock was unlocked even though I had locked it last night.
Can somebody shed some light on what might be going on here?

If you only want one wireless network, configure the AirPort Express (AX) to join the wireless network provided by the Qwest gateway.
When a lock appears next to the network name, it indicates that the network is protected by wireless encryption (WEP, WPA, or WPA2). If the lock does not appear, the network does not have wireless encryption enabled.
And when I went to the Network preference pane this morning, the padlock was unlocked even though I had locked it last night.
That is completely separate from the wireless network issue. If I remember correctly there is a setting somewhere to force it to stay locked but it has nothing to do with AirPort.

Network disappearance

This is the most random problem that I have seen in a long time. Before I go into it all I'll give you a little background information, I am running a 2009 Macbook with Mac OSX version 10.5.8 it runs smoothly as all **** and is amazing normally. Before anyone says I should go to the apple store to get technical help understand that I am temporarily living in China in a place where that isn't an option. With all of that info given check this...
At the academy where I am living there is one internet service being shared over two routers and a few cables. It used to be shared over 3 creating 3 networks, but one of them was turned off this weekend. Anyways lets say there is network 1,2 & 3. Networks 1 & 2 I could connect to, but number 2 is now dead, so we don't need to talk about that. Network 3 is out of my distance, but if I am close enough I can connect to it.
So I left for a weekend and returned and when I returned I discovered that I can no longer see network 1. Like my computer does not recognize it as there. I would assume that it is the router except everyone elves computers still works on it. Including two of my roommates one of which being a macbook user. I can still see network 3 and if I go to the other room I can connect to it, but even if I put my computer right next to the router of number 1 it does not see it. And, my ipod touch can be sitting in the same place as me and see network 1 but my computer does not...
So I've done all of the no brainers, restarted the modem, updated my software, turned my airport off and on, I've even done some more technical stuff, zapped my PRAM, deleted my wireless config files, even trashed my home directories System configuration. And so far, nothing. I'm going crazy. Has anyone ever heard of a network disappearing when everyone else can see it?
PLEASE HELP!
Thanks!

HELP ibook g3 OSX 10.2.8 no longer detects airport express wireless network

my ibook G3 OSX 10.2.8, airport admin utility software 3.1.1 no longer can detect the airport express wireless network (powerbook G4, OSX 10.4.11, airport admin utility 4.2; airport express, WEP protected, to DSL modem). i just installed an ipod driver update on the ibook, and wireless networking went down on restart. any help greatly appreciated!

you name it : com.apple.airport.adminutility.plist
delete it and do as advised.
This isn't harmful, because it is only a preference list, so it will be created brandnew as soon as you re-setup the Airport stuff.
Mac OS X ( especially Jaguar ) has a tendency to corrupt some plists out of the blue, it is more or less harmless and can be fixed with recreating them plus permissions-repair.
Hint : repair permissions more than one time, it ALWAYS finds something to fix in Jaguar.
You cannot destroy something with these actions, because it is Unix maintance so usual routines.
A tool like cocktail or Onyx ( google them, onyx is freeware ) can help you run such ( and more ) routines on a scheduled base.
Always remember that OS X is no longer "the Mac OS", it is Unix with a nice Desktop, the critical things run hidden in the background, so it has to be treated like any Unix/Linux sort of OS, even if from the outside everything looks nice and kosher..

PCs suddenly no longer see Airport Express wireless network - please help!

Hi,
I am new to this forum and I need help. Two days ago - without me making any changes to settings etc. my Airport Express wireless network at home was no longer visible to any of my devices except to the Powerbook (G4 OS 10.3.9) which controls it. From one second to the next two Vista laptops and my cell phone (Nokia, Symbian OS).
My Powerbook has no problem connecting through AE to the internet. The two laptops are both able to connect to other wireless networks so they don't seem to be the problem. I just don't understand what caused this sudden drop-off/invisibility.
I have already tried the following: resetting the base station, changing the channel on the base station (from automatic) removing the network security altogether (from WPA2). But none of the devices except the powerbook can now see or detect my network.
Please - if anyone knows what the cause of this problem could be or how to fix I would be very grateful!!

POWERMAC G5 can no longer access Airport Express wireless network

OK I've had a Airport extreme wireless network up and running for 3-years. Suddenly, my PowerMac G5 cannot connect. I know the network is OK because my Powerbook can connect to the network.
I've tried running the Airport utility and re-scanning with no luck. Also shut down the PowerMac and the Airport Extreme and then re-booted. No luck. The wireless strength meter in the upper right corner of screen goes from solid black to gray scale. Sometimes the network is listed, other times not. It never, however, will let me join the network.
Is it possible that the Airport card has failed??
Any help will be appreciated.

what does this have to do with windows?

My computer no longer recognises the Airport base station network

I presently have wireless broadband internet access on my iBook (using a Belkin wireless ethernet router connected by an ethernet cable to my airport.)
I also have an Airport Express in another room connected to my stereo for playing all my iTunes songs wirelessly.
The problem arose in that if i wanted to listen to my music I had to switch between networks, meaning i couldn't surf the net and listen to music at the same time.
A few nights ago I tried to 'merge' the networks using Airport set-up assistant (or admin utility, I forget which).
Now, my computer no longer recognises the Airport base station network, just the Express one.
Is there a way of listening to my music and using the internet at the same time, and how do I get my internet working again in the first place!
Many thanks
Jono

Rebooted Airport Express and now working

I've lost my AirPort icon in network settings - can't get wifi - how do I get it back..??

So I'm pretty green whe it comes to computers but trying to work through this....
My Macbook Pro's wi fi dropped out - I tried to re-activate it and inadvertedly removed the airport icon from my network connections options..
I'm assuming it's a fairly simple fix but I do not have the know-how.... Can anyone please help me work through this, it would be much appreciated..!!!
OSX 10.6.8
AirPort 5.6.1
thanks...

Hi ramayne,
I have the same problem with airport.
On 'Network' page when I try to add an interface AirPort is not an option.
I only can choose from firewire, ethernet, bluetooth DUN, VPN, PPPoE or 6 to 4....
How did you fix it?

Strange case of airport not detecting network

The airport menu often fails to show networks that are definitely being detected by the airport card - they show up strong and clear with stumblers - but I can't join the network either with the menu or the join network dialog. This can happen on networks that are very close to the computer - like three feet away - so not a signal strength issue. I often have to wait minutes for the machine to finally "see" my own airport. Curiously, it happens on three different networks, so I don't think it is just a problem with my own airport. Two networks are apple airports, the other a Linksys. I tried removing one of them from preferred network list, but that did not help.
Anyone any suggestions for resolving such a weird problem?

This past month I have been having problems connecting to my home wireless connection. Previously I had no problems whatsoever. I have tried unplugging the wireless router, turning off the wirless airport, deleting the network name from my list of server

This past month I have been having problems connecting to my home wireless connection. I have a MacBook Pro OSX Version 10.6.8. Previously I had no problems whatsoever. I have tried unplugging the wireless router, turning off the wirless airport, deleting the network name from my list of servers and trying to reconnect this way. These methods have worked temporarily, but the same problem keeps coming back. Most of the time my personal wireless connection does not even come up among the list of available networks. My fellow flatmates have PCs and both of them are able to connect to the network without problem.
The router is a d-link model DIR-615. I am not tech savy, so if any other information need to be provided in order to better understand my situation, please let me know.
Please help me!

If I open the list of networks in a window it says "connection timeout," but if I just select it from the drop down it tries for awhile and then stops with no prompt. When I try to run network diagnostics it says "sorry, we can't connect to the internet" (or some solution-free variation of that)

Airport Express WiFi network MAC address filtering not working

I have an Airport Express WiFi network which I bought and installed new in 2011. Initially I enabled MAC address access control and populated a list. It was working perfectly, I know, because a niece visiting tried to connect her iPhone and could not until I added its MAC address to the allowed list. Now however, anyone can connect without being added to the list. I think I read somewhere that a recent firmware update permanently disabled MAC filtering in Airport Express, even when it was previously working? Can anyone enlighten me about what's going on here?

In a sense those are/were/should operate as two separate functions, which they did before recently.
They do operate as two separate functions.....but it all depends on how you have the default rule setup in Timed Access.
If the default rule in Timed Access is set to No Access.......then a wireless device cannot connect....even it has the password for the network.....unless it has been setup on the list of allowed devices in Timed Access.
I have checked this 3 times this evening to verify. It works as it always has, and as expected.
If the default rule in Timed Access is set to Unlimited, then any device can connect to the network if it has the password. Devices that are listed or specified in Timed Access will be allowed to connect at the specific times that have been set up for each device.
So, if you want to use the more traditional MAC Access Control settings, the default rule has to be set to No Access and then you must set up a rule for each device that you want to allow to connect to the network. Only devices on the Timed Access list will be allowed to connect to the network. Other devices will not be able to connect to the network....even if they have the correct password.
If a recent firmware update has changed things from what they have always been.....then I am not affected....and I should be if I am using the same firmware as others.

Nokia n73 network disappears after sending a few c...

i am suffering from a unique problem on mine nokia n73 me
when ever i send continuous messages through the phone the network disappears and i have to restart my handset
it only happens when sending continuous messages it allows me to send a few messages without any problem
i am receiving calls and able to make call no network problem is there
what should i do....

this probably is a case of a bug in ur device so what u can try are:
U can go in for a hard reset which will turn ur device as it left the factory totally new and since u have no issue with the backup i think it wud probably do the trick
'*' '3' 'Call Key' and Power button all pressed at the same time after u have removed ur phone battery for at least 5 mins.
U can also update/reinstall ur firmware and see the result
In case of ur memory card there are different options available to you to get rid of the corrupt/unwanted data in your card.
menu--installations--application manager--remove the unwanted application....... in ur case internet tel
menu--tools--memory---options---format memory card......
remember everything including ur factory installed apps will be deleted......... but u can always download them later either from nokia or google them...
or insert ur card in any reader or laptop and check for virus and also the hidden folders....... check for any virus
the last option is to take it to ur care point and ask them to do the needful

I enabled the guest network feature on my time capsule. Can I configure my airport extremes guest network feature if I use this as a network extender using a "roaming" network?

I enabled the guest network feature on my TC. Can I configure my airport extremes guest network feature if I use the extreme as a network extender connecting my Airport Extreme to my TC via ethernet cable?

Unfortunately no, since the AirPort Extreme should be configured in Bridge Mode if it is connecting to the Time Capsule using an Ethernet connection.
The Guest Network option cannot be enabled when the AirPort is configured in Bridge Mode.
Another way of saying the same thing is that the Guest Network cannot be "extended" either by using an Ethernet connection or wireless. It is only available from the Time Capsule "main" wireless router on your network, not any extending devices.

Airport extreme/express network setup

i'm sure this has been covered in general but lan equipment and requirements vary widely (plus most of my wireless experience is w/non-apple routers), so here goes. i have the following hardware
airport extreme (802.11n) running 7.5.2 (might downgrade to 7.4.x based on comments in this forum) connected to cable modem
2 airport express (v6.3) connected wirelessly to ap extreme
1 airport express (v6.3) connected via ethernet (wd powerline) to ap extreme
what i'd like:
ap extreme base to be the only SSID & DHCP server on the network.
the 2 wireless expresses to provide wider coverage in the main house.
the express connected via ethernet to provide wireless signal/access in the detached guest house (trying to run it wirelessly does not get a strong enough signal, hence the powerline ethernet), but only as an extension to the extreme base.
when a device (laptop, phone, etc.) connects, it should use the closest / strongest wireless signal, but always think there is only 1 network/connection config. and, when one moves between house and guest house, connected device will auto 'roam'.
whoever set this up, set the extreme to be running in WDS mode (WDS main). however, it complains that it is the only WDS device on the network (see next ???).
the 2 wireless expresses are set to 'Participate in WDS' (WDS remote)
in order to get the ethernet-connected express to work, i had to give it its own SSID and set it to 'Create wireless network'.
it does work, but there are 2 networks, no roaming, and error message on ap extreme base re:WDS config.
questions:
1) what mode should the extreme base use ('Create wireless network' or 'Participate in WDS network')?
2) what settings (WDS or wireless) for the wireless expresses?
3) what mode should the ethernet-connected express use ('Create wireless network', 'Participate in WDS network' or 'Join wireless network')?
4) anything special i need to know to get the roaming to work reliably?
5) any suggestion (due to missing questions :-)?
tx for any info. i could try all the permutations & combinations of config (actually, i've already tried a number of them , but tired of running up/downstairs and to/fro resetting devices, so i thought i would ask for help from people with more experience background.

Hi, mackiemesser. Welcome to the forums!
So if I understand correctly, your setup looks like this:
<hr>
• Express #1, Express #2, and the Extreme should be set to "Participate in a WDS."
• The Extreme needs to be told that Expresses #1 and #2 will be WDS Remotes. (You'll have to enter their MAC addresses.)
• Expresses #1 and #2 need to be told that the Extreme will be their WDS Main. (You'll have to enter its MAC address.)
• Express #3 should indeed be set to "Create a wireless network" but should use the same SSID and password that your other wireless network uses.
• All Expresses should be configured to operate in Bridge Mode. In Manual Setup, click "Internet" in the toolbar and choose "Off (Bridge Mode)" from the "Connection Sharing" popup menu.
• The Extreme should not be in Bridge Mode. It should instead "Share a public IP."
<hr>
A few suggestions:
• Write down the MAC addresses of all your Extremes. This saves a lot of time when you're setting up the WDS.
• Sometimes after you change the WDS settings for one AirPort on the network, it confuses the other AirPorts in the WDS, and you get network problems until all of the AirPorts agree on WDS information. In this case, if you can't see an AirPort in AirPort Utility, connect that AirPort to the computer via Ethernet. In fact, it might save time to gather all your AirPorts and plug them in next to your computer for the WDS setup process so that you can easily connect via Ethernet if necessary.
• Using a WDS dramatically decreases your network performance. Every time you add a WDS Remote, you decrease your maximum network speed by 50%. Newer AirPorts support 802.11n and have a feature that allows you to extend your wireless network without as much overhead as a WDS, but all AirPorts in the wireless network that's extended must support 802.11n.

HT4145 Does the new Airport Extreme allow "guest network" setup across all my Airports on my network? I have 1 Airport as a router and 6 others as WAP's (bridged)

Does the new Airport Extreme allow "guest network" setup across all my Airports on my network? I have 1 Airport as a router and 6 others as WAP's (bridged)

I assume that all of your WAPs are hard wired on the network.
If.....all of your WAPs are simultaneous dual band Apple AirPort devices like an AirPort Extreme or new AirPort Express.....and.....you have firmware version 7.6.3 (now 7.6.4) installed on all the AirPorts.....and.....you use AirPort Utility 6.3.1 to configure the devices......in theory.....it should work.
I don't have 6 WAPs, but I do have 3 and the network works perfectly allowing extension of both the "main" and "guest" network.

My iMac keeps losing the connection to my chosen Airport Wi-Fi network. Anyone know why this happens?

My iMac keeps losing the connection to my chosen Airport Wi-Fi network. Anyone know why this happens?

Close all Apps and see if Activity Monitor shows any processes runnung.
Not that I think this is the cure but have you tried these resets:
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
The 5 second timing is important to a successful reset.
PRAM RESET
Zap the PRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
