Airport doesn't see networks

hello,
I am working on an iBook G3 running OSX10.3.9 and recently (september) added an airport card to my computer. everything was working fine until mid-january when airport stopped seeing networks - that is, it is turned on and set to see networks automatically, however, even when I am in places where there is a network (and where I have connected in the past), I am getting no bars (all of the bars for the airport icon are grey). I had my airport card tested and was assured that it is working fine - it was suggested to me that this might be a result of the software being compromised? I have just finished re-downloading and installing OSX10.3.9 but with no success - with respect to airport, everything is the same (all grey bars, no networks listed). I am very frustrated and need to be able to connect wirelessly again - please help!
iBook (G3) Mac OS X (10.3.9)

I'm hardly an expert, but I think I might have solved a somewhat similar problem.
Network Preference's Default setting stopped working. Each time I turned on my iBook I would have grey menu bars and have to go to InternetConnect in Applications to select a network, although I only had one, and my TCP/IP settings had not changed (Have you checked yours?).
Pulling plugs, zapping the PRAM, etc. did not work. What finally did, was going to HD/Library/Preferences/SystemConfiguration/com.apple.airportpreferences.plist and trashing that one .plist file.
After restarting, I got right on. Don't know if this will work for any of you, but it is easy to try, and I don't think can do any harm.

AirPort doesn't see my new wireless router

I have a new router, and it works perfectly well via Ethernet, but it also has a wireless aerial, so I wanted to use it wireless, but Airport doesn't see any WLAN (AirPort IS active). What should I do? Any idea?
Thanks
Silvia

The router does broadcast the network name.
My Airport card is AirPort Extreme, universal, version 405.1 (3.90.34.0.p18), and the router is 802.11g 54Mbps
It's an EU Powerbook and an EU router.
I have gone to the router's setup page but I really don't know what to do. There is an auto-setup function for the wireless but it didn't work. I didn't see anything about the wireless being allowed to join the network or not.

ESX 3.5u3 doesn't see network after firmware update on x6250

Hello,
We have got several Sun blade x6250 with ESX 3.5u3 with latest updates.
We have updated firmware on one of them from ELOM 4.0.45 -> ILOM 3.0.3.33 recently.
Now a ESX server doesn't see network:
Node ISOLATED form Network. Either repair network or override agent startup ...
I executed embedded PC-Check test, it saw all four NICs and said that they were 'Success'.
Also, I cleared statistic on a Cisco Catalist interfaces where the blade was connected.
After a day 'Receive' statistic is 0
Also, I tried to load the blade with DSL Linux, it didn't see network too.
Do you have any idea concerning the situation?
Thanks!
Regards,
Andrey.

Airport Extreme can see networks, can't connect to any

I recently bought an iMac G4 (1Ghz, 17") on eBay and am having problems getting the Airport Extreme card to connect to any network. It came with 10.5.1 installed and I've updated it to Leopard 10.5.8
I'm a bit of newbie with this Mac, but am learning quickly and I've tried to do my due diligence research prior to posting. I think I've tried every solution I've found recommended on forums for others with my problem.
Here's the basic info on what I've tried (by themselves and various combinations):
-changing the channel the network operates on.
-changing from WEP to WPA
-changing to no security at all
-changing to manual DHCP setup
-disabling Wireless-g only to allow b & g, and I've tried allowing only g
-I tried moving AppleAirport.kext to the desktop to let the system rebuild it with a restart - it was not rebuilt so I moved it back in and restarted again
-reset your router
-made sure router firmware was up to date
-creating a new network location
-went to Library > Preferences to delete com.apple.internetconfigpriv.plist and com.apple.internetconfig.plist but there were no files with those names in that folder
None of these options changed any response to the ways I've tried to connect to the internet.
It connects fine through the router with an ethernet cable. With this option it takes the network address 192.168.1.5
I also tried to connect to my neighbor's open network, with that network it will either timeout or ask me for a WEP password, which isn't needed.
These are the errors I get when trying to connect to my own network wirelessly:
-When I go through Network Setup Assistant, I get the error: "The password you entered is invalid." Even though I know it is correct (checked and rechecked to make sure all keys were working in a text file).
-When I go through System Preferences > Network I get a Connection Timeout every time it tries to connect.
-When I go through Network Diagnostics through Safari, it can't find any Apple Wireless Devices to work with or it gives me a connection timeout.
My iPod Touch 2nd Generation has never had a problem connecting to this router or the neighbor's open network.
Neither have any of my three Dell laptops.
AirPort Card Information:
Wireless Card Type: AirPort Extreme (0x14E4, 0x4E)
Wireless Card Locale: USA
Wireless Card Firmware Version: Broadcom BCM43xx 1.0 (4.170.25.8)
Current Wireless Network: wireless network not available
If it matters, I've got an Actiontec router and I'm connecting to Verizon FiOS.
Thanks in advance for any recommendations. I guess if the Airport Extreme card [or software] won't work I'll just have to try a USB network adapter (want to avoid this as this iMac only has USB 1.1).

Hi there!
Were any software install and restore discs included with the computer to support
the license and ownership, maintenance and help upkeep the computer's OS X?
Not sure where to begin in resolve the connection issues you have presented,
since I am almost under siege in my offline life with problems others foist on me.
Your issue may be in part due to a scenario where enabling WEP can causing
an issue of a self assigned IP address; the address sometimes may be just a
default and not that of the router's giving one to the computer. You can some-
times reset and hope the router can give you a new different IP address or DNS.
There usually is something else to this, if that is the case.
However, to make sure the computer itself is in a good state of health, and you
have some of the basic means at your disposal, (or to know what you have) is
why I am replying. And once that is mostly a certainty, to see if the settings to
choose the AirPort as a viable Network choice in the System Preferences, with
wireless on top of the available options open to the computer. You can drag in
order of desired connection type, the Ethernet, dialup, Airport, etc - means of
making or sustaining a connection in the Network panel. If these items are not
correctly chosen, the available wireless Airport won't work. And the status of
the Airport connection won't be visible in the main menubar header either.
Have you been through some of the several Apple Support documents on topic?
• Mac OS X: Connect to the Internet, troubleshoot connection & set up small network:
http://support.apple.com/kb/HT1714?viewlocale=en_US
• Mac OS X: Troubleshooting a cable modem, DSL, or LAN internet connection:
http://support.apple.com/kb/TS1317
• AirPort troubleshooting guide (primarily settings & base station)
http://support.apple.com/kb/HT1401?viewlocale=en_US
For computer basics, to check and do simple software maintenance of the Mac
OS X, you can boot the computer in SafeBoot (shift key held on startup until a
login window appears) and from GO in main Finder window, see Utilities folder
in the drop-down menu, and look for then launch Disk Utility from the Utilities.
In Disk Utility, choose the Macintosh HD, then 'repair disk permissions'. You
may be able to later click on the hard drive icon of the Brand of the HDD as
seen in the same sidebar where the Macintosh HD was located, and choose to
'verify' the hard disk drive from the choice in the Disk Utility panel then available.
When done with these items in Disk Utility, quit it; then restart the Mac normally.
{For other levels of Disk Utility repair on the hard disk drive, you need to boot the
computer from the OS X Installer's disc#1 and choose Disk Utility from its menu
bar prior to actually running that Installer. The drop down menu bar has options
and select them carefully; since you can do quite a bit to the computer's drive if
the wrong item is chosen out of turn or when not needed. A booted disk utility is
in a position to act more thoroughly on a hard disk drive that is then unmounted.}
If the computer is in a good state of preventative maintenance and permissions
repairs, etc the main issue would be in the choice of settings to access the internet
via the means at the computer's disposal; and choosing the hardware path in the
Network panel of System Preferences is one of the main portals. There are several
items in here, including being able to check-mark and move the order of importance
the main items in a Network preference window, so the computer chooses them first.
If the antenna cable and other connect to/from the AirPort card in the base of the iMac
is properly pressed firmly into position and the card is OK, the physical and electronic
paths should be assured; as far as that goes...
Some of the changes to settings may not have been necessary or help in connecting;
so I am not so sure what ones would need to be changed back to their defaults.
Good luck & happy computing!

Airport card can see networks but can't connect all of a sudden

I have an older MacBook running 10.6.8 (snow leopard) and it's been working fine. All of a sudden, it can see networks, but cannot connect. I get an alert with an exclamation point and "no Internet connection". My iPad can connect just fine; same network, same location as usual, so I know it's not an issue with the network/router (my husband's computer works fine as well). If my airport card went, I wouldn't be able to see any networks at all, right? Is there anything I can do? My AppleCare has run out, due to the age of my computer and I don't want to put hundreds into fixing it, either (nor can I afford it). Has anyone had this happen? Any suggestions? Thanks!

Airport card not seeing networks after IP address clash

Hi - I have a wireless network that works fine, just reset it up again and my two mac laptops connect perfectly well to it, as they always did. The reason I set it up again was that my desktop intel mac pro (my main computer) was giving an error message, that another device on my network had the same IP address as my Airport card, and that it therefore couldn't connect to my wireless network (which has been set up so that the various devices are given their own IP addresses automatically in Bridge Mode). I have never seen this before. I repeatedly tried 'renew DHCP lease' in system preferences - it had no effect so I set up the network again from scratch to see if that would help. Still nothing. The mac pro cannot see either of the two Airport Extremes in my network using airport utility and nor will it connect to the new network when I put in the name and password - again, I have tried repeatedly. The Airport icon in system preferences is orange.
The airport card has never reported any problems and Apple hardware test (as well as the programme that came with Applecare) indicates that it's working normally. There are also no hardware problems with the Mac Pro according to the same tests.
Does anyone on this forum know what I can do to connect the Mac Pro to the wireless network? (I don't have the option of trying to use it as the computer that sets up the network, as it's located a long way from the telephone connection, so that is done using Airport Utility via one of the laptops).

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 doesn't see printer

I have a new Airport Extreme, and an older HP 7660 printer, with a new Mac laptop. Everything worked fine. THEN we moved the modem and consequently the Airport and printer. I didn't have a long enough USB cable, and left the printer unplugged into the Airport for a few days. When I plugged it in again the airport didn't see it. I've tried everything. Several times. I can print with the cable in the computer. The Airport is on line. I've turned things on and off, disconnected, and reset the airport to factory settings (with the cable in) and set it all up again. Nothing is working. Any suggestions?

I wish I could say that that fixed it, but it didn't. I was unable to set up the second AX unit as "extend an existing network' due to inexplicable errors related to the change also requiring changing settings on the #1 AX.
Next, I also tried creating a whole new network on the second AX just for the printer, but it didn't come back online (blinking yellow, invisible in Airport Utility) after I created it and I had to reset it manually and start over.
It would help if I could find better documentation on it that explains what the various settings do. The manual is a little slim and the various settings are not familiar to me, therefore it's very confusing.
And, sigh, after all of this, I performed a speed check and found that by connecting through the Linksys Router/Switch, my speed dropped back to the same level as before I started this fiasco.

Error saving Project 2010 files to network drive - doesn't see network drive

ANSWERED (11 April 2014):
So it seems the resolution to this is to simply create a new share with a different name. I used the existing folder (to retain NTFS permissions) and just select to Add a new Share (applying the same Share permissions as the non working Shares).
Deploying this new Share via Group Policy as a test resulted in staff being able to open files from Windows Search, save files through MS Project and the Share being accessible through browsing SMB.
All problems resolved by using a new share name for the existing folder. Seems to be a corruption in the namespace.
Note: I had previously deleted the share and recreated it. I had removed all NTFS permissions and readded (through both the GUI and icacls). This didn't make a difference.
Only changing the name of the share fixed the problem.
Original Question
Already
posted here... but Microsoft Support has not responded.
It seems some staff on some computers are having problems saving MS Project files to the network. This is only since an upgrade to SBS2011 (from SBS2003). The only difference now, is that network drives are mapped via group policy rather than a 'net
use' script.
This is affecting users on Windows 7 and Windows Server 2008 R2, with either MS Project 2007 or 2010. The users have full change access to the folders and can create new files and modifying existing files, just not a MS Project file. Other file tyes, e.g
Word .docx, Excel .xlsx, Adobe .pdf files, all work fine. These files can be opened, edited and saved normally without problem.
To replicate this:
The user opens an existing file or creates a new file on the network folder (either through Windows Explorer or MS Project). They then click File > Save in MS Project and receive the following error (see pic below):
An interesting symptom of this is that if you select File > Save As in MS Project, the Sae As dialog box doesn't remeber the path location of the network drive. MS Project instead prompts to save the file in the local users documents folder (see pic below):
If they browse back to the original folder where the file was saved and choose to save it there, they are of course, prompted to overwrite the existing file and they can save the file. But the same thing happens every time they open the file.
It seems the problem is that Project isn't seeing the path of the file or that the network drive is attached.
If a user closes the file without saving it, they are prompted to save the file and the prompt shows the drive path:
Do you want to save changes to "N:\... Projects\Active Projects\CC...\F4 Project Plan File\004 Programme\test project file.mpp"?
But choosing to save the file gives them the same result as Save As, they are prompted for a new location as if the original file location doesn't exist.
I have disconnected the mapped drive and connected it again using net use but get the same error.
I have reinstalled MS Project 201, installed Project 2010 SP2 and installed Windows updates and it does the same thing, exactly the same symptoms.
Further, if the user opens a file from the network drive, the file shows in the Project recent files list. If they try to open the file from the recent files list in project they get the following error:
"Project cannot open the file.
-Check that the file name and path are correct.
-Check that the file format is recognized by Project.
Project files saved in a version earlier than Microsoft Project 98 can't be opened...."
This is a test file that I created on the user's computer and network drive, This is being opened with the same version it was created in. If I browse to the folder in Windows Explorer I can open the file. Of course, I then can't save the file (I still get
the original error). I'm logged on with Domain Admin privileges.
I've checked these links from other threads (neither apply to my scenario):
http://support.microsoft.com/kb/983458/en-us|
http://social.technet.microsoft.com/Forums/en-US/excel/thread/2eeea140-7e6c-4cb9-a89b-06d2102bd9f7/
I've downloaded my TechNet version of he software and installed it with Sp2 and Windows updates and it does the same thing. This also happens on the Remote Desktop server (Server 2008 R2) using MS Project 2007.

Case 1
This error message appears when the document is open on two or more computers that are running different operating platforms. For example,
if the document is open on a Macintosh computer and you open it on a second computer running Windows or Windows NT, the error occurs when either user tries to save the document.
This problem stems from a difference between the ways Macintosh OLE and Windows OLE open files. As a result, you cannot save a file on two different operating platforms at the same time.
Case 2
This error occurs in Word 97 for Windows if you save to a MAPROOT type network drive connection on a NetWare server where spaces exist in
the file or folder name.
Case 3
This problem may occur if an anti-virus program running on a network has the ability to scan for macro viruses in documents in shared network
folders.
For example, if you have the following:
a shared folder on a network server
-and-
an anti-virus program is running on the network server that is set to monitor the shared folder,
when you attempt to save a document (across the network) to the shared folder, the anti-virus checker may cause the error to occur.
Case 4
This problem may occur on Novell networks when the AutoRecover files path is either blank or set to a network drive.
According each, please try the following workaround:
WORKAROUND
To work around this problem, use one of the following methods appropriate to your situation.
Case 1
Method 1:
Move the document to your local hard disk for editing. Move it back to the server after you finish.
Method 2:
Save a copy of the
file with a different
file name, and work on the copy, either on your hard disk or on the server.
Case 3
Method 1:
Move the document to your local hard disk for editing. Move it back to the server after you finish.
Method 2:
Do not use spaces in the directory or document names.
Method 3:
Do not use MAPROOT-drive connections. Map your drive connections to the volume-level only.
Case 4
Turn off the anti-virus protection on the network server and then try to
save the document. Contact your anti-virus protection software company for additional details and/or updates to their programs.
Case 5
Set the AutoRecover files path to your local drive. To change the AutoRecover path, use the following steps:
1.
On the Tools menu, click Options.
2.
On the File Locations tab, select AutoRecover files and then click Modify.
3.
Change the Modify Location dialog box to a
folder on your local drive and then click OK.
4.
Click OK to close the Options dialog box.
Hope that helps.

IBook 14" 600 - Airport - Can't see network

I just upgraded to the Extreme N Airport Base - Now I can't get my old iBook 600 to see the network (My MBP and MacPro see it fine).
I've tried the 802.11a compatibile setting as well as the b/g. Neither allows it to be seen.

802.11a uses 5 GHz which the iBook can't use at all.
The AirPort Extreme base station (AEBS) must be configured to operate in an 802.11b/g compatible mode.
Try configuring the AEBS to use a channel between 1 and 11.

Airport doesn't find network anymore

Hello,
since 2 days ago i have a problem finding my wireless network.
The first thing i did was to reset the airport base, which worked. my powerbook found the network again. Then another weird thing happened when i tried to set the password back. I told me that my computer wasn't WPA-capable. But I used a WPA password all the time before and never had an issue.
so i set it to a WEP 128bit password and it worked. but now since 10mins it won't recognize the network AGAIN. I reset the base again but still the network doesn't appear but other networks do. just not mine
my roommate's laptop (Windows XP) recognizes the network btw
is it possible that i caught a virus?
thanks for any help
thomas

is it possible that i caught a virus?
Not likely at all.
One thing that can work, try this, please ignore the exact symptoms and connection and Hardware types, it's worked for many others than the stated...
http://docs.info.apple.com/article.html?artnum=304482
It's worked for WEP, WPA/WPA2, G3s, G4s, G5s, Desktop, and laptops.
The Interface that connects to the Internet, needs to be drug to the top of Network>Show:>Network Port Configurations and checked ON.
Does rebooting the Mac only fix it temporarily?
Was the Mac going to Sleep before the disconnection?
Next time it happens try one or both of these lines in Terminal...
sudo ipconfig set en1 BOOTP;sudo ipconfig set en1 DHCP
sudo ifconfig en1 down;sudo ifconfig en1 up

PS CS4 doesn't see network printers

Hi. I have installed some network printers on my PC, and PS CS4 doesn't list them. It only lists local printers installed on my PC and the Adobe PDF (I have Acrobat). That is under File > Print... and also under File > Page Setup... > Printer... . All the other applications do list the network printers I have installed. Any idea what I am doing wrong?

This might help you: The info is a little ways down the KB.

Airport doesn't find network after startup when wireless router is hidden

If I have the Wireless Network setting on my router set to "Hide Wireless Network" my Mac can't find the network after I have restarted it.
If I leave the "hide wireless network" box unticked everything works fine, but I would prefer to have it hidden.
Two windows-based laptops also use this router and they work fine with the wireless network hidden.
The router is a D-link DSL-2740B.
Has anyone else had this problem?

I also confirm the same problem. I do not have any bridges etc on my network. Direct connect from Comcast cable modem to Airport router. The only way to set it correctly so far is to allow the network name to be visible. Whats strange is that I have this same router type at my other place and the other one is working just fine. Perhaps there is some slight hw change recently?

Airport Delay Before Seeing Networks

My MacBook has been having some serious wireless trouble lately. If I start the computer or wake it up from sleep, it won't see any of my wireless networks for several minutes. If it does see any wireless networks, it won't allow me to join, citing a network timeout every time I enter my password. After about 5 minutes or so, I am able to see my wireless network and can join with a strong signal. It's almost like the computer's wireless needs to warm up before it can join any networks. I'd like to think its a preference issue, but I set up a new user to test out and the problem still persisted. Any help would be appreciated.

Posted: Nov 17, 2007 7:04 PM in response to: sgginc Reply Email
This is going to sound crazy, but I think my problem is fixed. I use a Kensington Studio mouse on my Mac. I had the double click speed set to slow. When I hike up the double click speed the faster my folders would open. I messed around with the mouse settings slow and fast.
Thanks to all for the advice.
This is how I fixed the same for my Mac. I like to have the double click speed set to the slowest setting, but this makes the Finder faster this way. Try it and post back.

Airport doesn't detect network occasionally

I have an older macbook(2.2GHz Intel Core 2 Duo, Build 9J61) which I just bought last year which occasionally does not not detect my usual preferred network. This happens usually after I put the macbook to sleep. I then have to reset my router or restart my macbook to solve the issue. This often gets frustration as doing the following is very time consuming and resetting the router often annoys my roommates. Is there another way to solve this?

When the network isn't detected, have you tried simply turning AirPort off and then back on via the AirPort menu bar icon?
That works when it sporadically happens to me.

Airport doesn't see Internet

Hi
My airport has just stopped connecting to the Internet. The signal strength displays full strength (wherever I am) and doesn't connect to anything.
This is the first time it's happened since the last mac book firmware update the other day.
It also reports a fault when in Windows XP (bootcamp), so it would seem that it's a h/w issue.
Any clues most appreciated, there's no way I can let it go off to Apple for repair, I just don't have a replacement.
Thanks
Wendy
P.S. my ethernet ports work okay, just not the airport.

Try resetting the PRAM and/or SMC:
