Airport extreme can't see any wireless networks.

Hi, I have an iMac that has always used an ethernet connection to the internet, but now I want to connect wirelessly. But it doesn't seem to "see" any networks, mine or otherwise, which work fine on my other apple devices. Does the fact that my wireless card was purchased (as was the imac itself) overseas make it incompatible with US wireless networks? Or is the card broken and I have to take the computer in for repair? Or is there some way I can resolve it myself?
Here is what my Airport card info says:
AirPort Card Information:
Wireless Card Type:          AirPort Extreme (0x14E4, 0x88)
Wireless Card Locale:          Asia Pacific
Wireless Card Firmware Version:          Broadcom BCM43xx 1.0 (5.10.91.22)
Current Wireless Network:          wireless network not available

Yes, it does. Still doesn't "see" any networks. If I need a new airport card, is this something I can do myself or does it have to be done at an apple repair shop?

My airport express can't see my wireless network

I am bringing up a new AE in my wireless network. I have set all the internet and wireless configurations. I am trying to add it as a client, initially connected to my router via ethernet. After tweaking several settings I am now down to what seems like a critical problem: Airport Utility tells me that my AE cannot see the wireless network. This is a bit amusing since I unplugged the ethernet and am communicating with it solely via wireless.
My config: static IP addr reserved in my router, WPA2 encryption, ethernet clients allowed, using my router as the default DNS server. Running the latest firmware and Airport utility according to Apple Software Update this afternoon. Router is an SMC Barricade N with latest firmware.
Any and all advice greatly appreciated.
Roger

Thanks for the ideas, but alas those are not the cause.
I am broadcasting SSID and I am running mixed b/g/n mode. FYI Airport Utility finds my network OK, as do the many other pieces of networking equipment in my house (4 computers, a NAS, an SMC wireless client, etc etc etc.) Even my son's Touch, after going through very similar games with Apple, solved by an OS upgrade a couple months later...but I digress.
Spent an hour with the Apple expert on the phone verifying everything was right on the AX and then took it to my local apple store where they were able to connect it to their G router as a client - thus eliminating wrong AX config and broken HW as a cause.
Here is what I know: it has to be able to see my router because when I bring it up my router sees it and issues it an IP address. I might reserve the IP and then set it to always use that. That is one of the things we did to get the Touch working initially.
Again, thanks and any new ideas appreciated.

Can't see any wireless network on my g5 dp2.5 can anyone help?

hello - i have just bought a 2005 model dp2.5 g5, and an airport extreme card. I have a wireless network at home which my other macs are all seeing fine, but this new computer won't see any network at all. i tested the extreme card by putting it in my laptop and it works fine. have tried to log on manually but again the computer doesn't see any network. the airport logo is there on the top menu bar but with no signal.
any ideas?
Tony

Very similar topic. I have a g5, but I have a windows desktop, windows laptop, and xbox360. I have an airport extreme card with the antenna in place. The two windows machines have their wireless network cards and antenna.....the xbox has it's wireless adapter. When I start up the machines, the three microsoft machines connect just fine, the G5 won't connect. I can run an ethernet cable to the Linksys G router, and sometimes that kicks in the airport card. But who wants to do that every day.
I can share files between the two windows machines, but not to the powermac. not sure about the xbox360.....the wireless adapter is an xmas present. But connected via ethernet cable, the xbox won't work with anything.
Help please.
Harry.
I just bought a new router with the notebook which I got a couple of weeks ago. The old router was a B and the new one a G, but that is moot. Everything is backwards compatible....and none of the machines support X.

IMac suddenly can't see any wireless networks!

I have a recurring problem with my iMac 20" Intel Core Duo.
For some reason, it suddenly loses the ability to see wireless networks. The problem is resolved if I restart. I go through this several times each day, and the frequency of the problem is increasing.
Strangely, there is nothing wrong with my Airport Extreme wireless network. My other computers see it just fine.
And when I check the Airport indicator at the upper right-hand side of my iMac's desktop during this problem, it shows NO wireless networks at all! And I have 7 neighbors with wireless networks on 24/7!
As I said above, the solution has been to restart my computer, at which point all the networks appear again.
Can anyone offer a solution/explanation? I have tinkered with my network settings to no avail.
Thanks in advance for any suggestions.
MacBook Pro, iMac 20" Intel Core Duo Mac OS X (10.4.9)

It has to be unrelated because I too have been having the same issue for the past 2 weeks. Actually it seems that ever since I reloaded the last iMac intel update (which I had to do to get my iSight to work again)
I've been having this issue multiple times a day. I even moved my iMac thinking I had too much distance and walls between the router and the iMac.
I know it isn't the router because the laptop in the house picks up a very strong signal all the time.
I tried switching channels on the router (a linksys) and it has seemed to help a bit. I am now down to dropped signals only about every other day.

Ipad can not see any wireless networks

So I updated my iPad's operating system last night, and my wireless connection to my home network worked fine. Now I'm at work (in a midtown Manhattan office building, where my laptop recognizes about 50 networks) and it can't see a thing.
I don't have the ability to unplug the router, and at any rate this is clearly an internal issue as it's not missing one network, it's missing dozens. I've restarted, reset wifi, reset network settings, toggled airplane mode, etc etc etc. Any other suggestions? Inevitably, it's on an afternoon I have a major facetime appointment.

Try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.

IBook G4 Airport Extreme does not see any SSID

Hi,
My iBook 1,2 Ghz has been working great for several years now.
I am working with Mac OS X Tiger (10.4.11) for quite some time
and it never let me down. I connect to the internet using an Airport Express
connected to a speedtouch router.
The Airport Express Card in my iBook always found 6 or 7 SSID's of other
Wireless Networks in my neighbourhood and it used to login automatically on
my Airport Express wireless wetwork station.
Last week it suddenly stopped working correctly.
After starting OS X on my laptop the little Airport icon in the upper bar faded out grey.
When I click it it says it can't find any networks.
I checked all my settings, downgraded my Airport Extensions
and even installed a spare (refurbished) Airport Extreme Card.
Even with another Airport Extreme Card it does not see any wireless networks.
My other macs, a unibody MacBook Pro and white MacBook work fine with the Airport Express.
What could be wrong? Am I overlooking something here? Can somebody help me out?
How can i get my Airport Express/iBook G4 connected to my wireless network again?

Hi Elko,
Thanks for the reply.
I re-installed the original Airport Extreme card into the slot again.
But now i pushed it harder than the first time. (just like you said)
I noticed the second click, but that doesn't seem to be the problem.
Both Airport Cards (the original and the new) were installed correctly.
I also checked the antenna connection but that is seated o.k. too.
After re-installing the card, i booted into Mac OS X Tiger and checked the ASP.
It says a Airport Extreme Card is installed with firmware version 405.1 (3.90.34.0.p.18)
and the langauge version is international/worldwide. So far, so good.
Nevertheless the airport card does still not find any wireless networks or SSID's after
scanning multiple times. (Location on automatic)
I am planning an upgrade to Leopard today. Maybe that's gonna help, since there were some Airport Extreme updates in Leopard. If that's not the solution, I will stay with your other suggestion and buy me a nice USB dongle.
Do you have any idea what type of dongles work best with Leopard? I have seen some different models, but a lot of dongles require third-party software to make it work and are not automatically recognized by OS X.

Cannot see any Wireless networks

After installing the latest security update for 10.3.9, I can no longer see any wireless networks. I have tried reseating my airport card along with unpluging the antenna with no luck. I have also repaired permissions and trashed the Network Interface preference file, again nada. Another suggestions would be greatly appreciated.
I have a relatively new Airport Express base station at home and I have also tried testing the connection at several wireless hotspots.

I had the same problem and that's why I ventured here for the first time after an hour's battle this morning.
My solution: restart the computer. Just when the menu has gone out of sight, you get the Keychain pop-up box informing you that the airport application has been changed and whether you wish to allow Keychain access to this new version as well. Here's the tricky part. You must react within 1 (one) second to the pop-up screen and click the "always allow"-button. Once the computer has rebooted, you should have access to your Airport network once more.
Clunky? Yes. With me, the problem was even more bizarre. I could see my trusted network in the Airport drop-down menu but even if the computer seemed to connect to it, I couldn't get an IP. Sometimes the whole upper right corner icon bar would freeze if I tried connecting.
Puzzling? You bet. I'm rather perplexed as to why I couldn't just solve this problem by removing and re-adding the Airport Keychain entry with the new version. I can only conclude: thank you, Apple, for making patches that work.
Experienced people: how do I relay my bug report to Apple?

Mac Mini - Core Solo - Won't See Any Wireless network

I have a Mac Mini, first gen Intel, Core Solo, that won't see any wireless networks. However, it will see my extreme basestation, and my two airport express devices over bonjour, which makes me think that the wireless device is working.
I've reset the PMU, with no luck.
Any suggestions?

Does an Airport card show in the system profiler?
Is Airport switched on in your mini - the Airport icon in the menu bar should show at least grey bars rather than an empty white 'fan' shape?
With Airport on, when you click on the Airport icon, does it show any network?
If you click on 'Join Other Network' and type the name of the wifi network you run, what error message does the system give?
How far away from the wifi base station is the mini? What kind of structures and environment is it in?
If you move the mini to be in close proximity to the wifi base station, does it show any signal?
When you download a copy of AP Grapher (http://www.chimoosoft.com/apgrapher.html) and run it, what does it show for signals, noise etc?
How is the mini seeing any wifi devices via Bonjour - do you have it wired into your network? If so, the fact that the devices appear via bonjour doesn't mean they are transmitting wifi, nor that they are in range.
By the way, the Core Solo mini doesn't have a PMU to reset. If you used the PMU reset procedure it won't have helped, and may actually have caused problems. The correct procedure for an Intel-based mini is an SMC reset, as follows:
-From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
-Unplug all cables from the computer, including the power cord and any display cables.
-Wait at least 15 seconds.
-Plug the power cord back in, *making sure the power button is not being pressed* at the time.
-Then reconnect your keyboard and mouse to the computer.
-Press the power button on the back to start up your computer.

My iphone can't see any wifi networks

my iphone can't see any wifi networks ... i tried to reset network setting and reset all setting and update the ios system but no way

I, too, fear it might be a hardware problem . I removed all security from my router but still no networks appear in the list nor can I connect directly by typing in the SSID. Tried two routers: Apple Airport Extreme and a Linksys something-er-other provided by Bell.
I will give HP a call tomorrow and see if they can sort this out.
Thank you for your help/advice!
Edit: almost certain it's a hardware problem: I clicked on the Help button while on that "Scanning for networks" dialog during initial setup and as one of the "helpful" suggestions, it said my Mac address was 00:00:00:etc.

Satellite L300-17L - don't see any wireless networks detected

Hello all,
I just bought a Satellite L300 - 17L. All drivers seem to work except for the wireless card.
First, I installed the driver pointed by this site but I discovered that the card is actually an Intel Pro 3945 card, not Realtek as specified in the driver section.
Now I installed the driver for the INTEL PRO 3945ABG, version 11.5.1.15 and also the PRO Set utility, and I don't see any wireless networks detected.
I have a colleague that sees many networks using the same adapter but on a other Laptop.
I also tested the switch on the Laptop and it is on.
Did you experience this kind of problems on your system ? Please help me because I am really sad because of this issue.
Thanks & Best regards
Valentin

Hi
As far as I know this notebook was equipped with the Intel 11a/b/g WLan card.
You should firstly check if the WLan router and the WLan card use the same WLan standard.
In the WLan card properties (in device manger) you could check this settings choosing Advanced tab.
I would also recommend checking if the WLan was enabled properly
Bye

Can no longer see any wireless networks

Hello,
I've had my macbook for just under a year now and have never had a problem seeing/connecting to any wireless networks in the past. However, over the past few days I have had issues connecting to my router. It keeps kicking me off every 15 or 20 minutes and when I try to reconnect it often gives me a timeout error. I have reset the router countless times and have even reset it to factory settings and triple checked that the firmware is up-to-date. I felt it was a router issue until this morning; it kicked me off so I reset my router and turned my airport off&on but now I cannot even see the network nor the other 10 (or so) networks that are typically viable. Since I cannot even see the wireless networks across the block anymore I seems like this has to be a computer issue (or at least the computer has to be involved to some degree).
I've tried to make an appointment at the genius bar but they are booked solid, as in they don't have any available appointments available at any time, even days in the future. Has anyone seen this problem before? Is my wireless card is on the fritz? Does anyone know of any potential software issues that could cause this?
Thanks in advance.

You can skip the Genius Bar and just call AppleCare directly.
However, a couple of suggestions:
• create a new location in your Network preferences; does the problem persist?
• create a new user and log in to that account; does the problem persist?
This one's more extreme: Do an Archive and Install, which will completely reinstall the system but preserve user accounts and data:

If these don't help, then it may well be hardware.
Good luck!

IMAC can not see any wifi networks at all?

IMAC can not find any wifi network at all. A few days ago the Imac suddenly had no wifi and on turning the WIFI on and off it became apparent that when it scans for wifi it can see no wifi networks at all. I have several other computers and they all see the wifi networks fine. I assume it is a hardware issue but the hardware test I preformed comes up with no errors. Anyone got any ideas?

Can I use an Airport extreme to extend my ATT wireless network?

Hi
I get my internet through an ATT DSL wireless router positioned up in my attic. I have a studio in my basement with 2 computers, a plotter, a laser printer and a fax/scanner/photo printer. I've run an ethernet cable down from the attic in to a central location in my basement. I've run ethernet cable from the three printers to that same location. I want to set up an unused Airport extreme base station in my studio to connect the plotter and two printers to my wireless network. One snag is that one of my computers has a bad airport card slot and needs to be connected to the network with an ethernet cable.
Can you help me solve this?

OK,
Got er done this weekend and I have extended the network to my studio. One problem though, My main computer keeps dropping off the wireless network. It connects for a second and then gone. I have solved this for the moment by disconnecting my scanner from the AEBS and connecting my main computer to the AEBS. I still have not connected my laser printer to the network, but will use its USB connection to connect it to the AEBS. I just need to go buy a longer cord.
Things work for now and I can work on some jobs this week. I plan to search the boards to solve the dropping off problem soon.
Thanks again for all of your help.

How to use Airport Extreme to create a second wireless network with different IP addresses behind an existing modem/router?

Hi,
I have an existing modem/router from my ISP that does DHCP and NAT with base IP 192.168.1.1 distributed in the wireless network. I use this wireless network for our private devices. I could turn off the DHCP server in this first router, but there isn't a separate setting to turn off NAT.
I want to connect my Airport Extreme (4th gen) to this existing router to create a separate wireless network for visiting guests, where IP addresses of 10.0.0.0 etc. are used. So I do not want to use the Airport Extreme in bridge mode, as I would like to keep the devices on the first network 'invisible' for those on the second network. (P.S. when connected in bridge mode, the Airport works well and can distribute a network with a different name from the first. It's just that I would feel more comfortable about our privacy if the Airport were to distribute a different IP range. False security, maybe?)
I've tried doing this by 'Sharing a public IP address' in Airport Utility's Internet tab, leaving TCP/IP's setting to 'via DHCP', setting DHCP addresses to start with 10.0.0.2 up to 200 with all else blank, and not using a standard host nor NAT-PMP in the NAT tab.
When I do this the Airport complains of a 'double NAT issue'. Internet connectivity seems to be OK, but when switching between the two networks on my Mac I get complaints about my IP address being in use by another device intermittently.
Can anyone help in how to get the 'double NAT issue' resolved?
Thanks!

So if someone is connected to the modem/router network they will be able to see the HD I will have put in to the AirPort Extreme?
As I said above.....since the modem/router and AirPort are bridged, devices on the modem/router wireless will be able to "see" devices on the AirPort wireless, and vice versa.....
If they can see the HD connected to the AirPort Extreme, will they be able to access it
Yes, unless you plan to password protect the drive connected to the AirPort Extreme.
or will they still need the password needed to get onto the AirPort Extreme network?
The modem/router and AirPort Extreme are bridged. They are on the same network. All devices are on the same network when the modem/router and AirPort are bridged. Not sure how else that I can say this.
Also, because it is bridged, I shouldn't have any problems accessing the HD I will have connected to the AirPort Extreme from an external location?
Accessing devices from a remote location is never easy....and a topic for a different post/discussion. If you have a "static" Internet IP address from your provider, and have all the details on how to forward ports on your modem/router, you are off to a good start.
Apparently there is some addressing issues because devices can be seen as "Double IP" because the modem/router would have allocated IP's as well as the AirPort allocating IP's thus making connections slower until resolved
When you "bridge", all IP addresses are issued by one device. There will be no conflicts on the network, since they are bridged.
Once again, in very simple terms, you have two doors (access points) that open into the same room (network). One "door" is the modem/router and the other "door" is the AirPort Extreme. They are on the same network....("room") because they are bridged.

Airport extreme can't see any wireless networks.
