Leopard not recognising wireless networks

So I clean installed Leopard on an external HD, but network preferences wont recognise my wireless network or any of the other five I can usually see from here. However, when I am presented with Network Diagnostics option I can see all the wireless networks I would expect, and am able to log into mine. Problem is if the computer sleeps, or if I tinker with the Network Preferences, the connection drops again. Anyone having this problem?

I've also been having this problem since installing Leopard. Every once in a while, my connection will drop (the greyed-out AirPort signal will appear) and Adium will reconnect. This happens sometimes four or fives times in a row. I found that rebooting the airport card via the menu bar fixes it temporarily but it returns.
I also cannot see the other networks in my neighborhood from the menu bar, but can from the Diagnostics. Mine comes up in the networks menu but I have the feeling if I did a fresh install of Leopard, I would have the same problems as the previous posters. Since this is a fairly bad bug in Leopard, I'm sure Apple will come out with a fix for it. It is a new release, afterall. I trust Apple with their updates.

Airport not recognising my network.

Hi. I have had a peculiar problem for the last few days: Airport is not recognising my network so I can't get online via wifi. When I plug in the LAN, then I get the connection right away. Airport (Extreme) recognises other networks so it's not that it has stopped functioning and my wife (who uses the Windows O/S) connects via wifi through our network. I have tried shutting down everything and startng up again after a gap of 5-10 minutes. That seemed to work once but hasn't since. I've tried uninstalling my network, removing any links on the keychain and then reinstalling, all to no avail. I have a 13" Macbook aluminium body which is still under the 3-year warranty period. Before I approach Apple Support, is there something that I should do? I have a feeling that somehow this can be resolved fairly easily, but then I admit to not being a computer expert by any means. Any help would be appreciated. Thanks.

If there is nothing connect or using to the airport express, you can try to reset the airport express back to standard.
And the default password is "public" if I am not mistaken.
And see if your MacBook can connect using that open wireless connection.
Good Luck.

Satellite not showing wireless networks, adapter seems ok

my satellite is not showing wireless networks and i can't figure out what networks are available. the adapter seems to be working properly according to windows device manager. i had to uninstall configfree, although i'm not sure that caused any problem. i have had to run a bunch of anti-spyware programs, registry cleaners etc., system seems much better but a few glitches.

It's possible, but it might be a lot more work to do so. It all depends on how soon you need to get it fixed. I'm not a network specialist so I can't really offer much in the way of assistance other than what I already did. It's possible someone else might have other ideas, but since you didn't post this in the Networking and WiFi Forum where it belongs it's quite possible that those networking specialists will never even see your post to respond to it. I know that I rarely go into the Networking Forum as it isn't my strong suit.
If you don't post your COMPLETE model number it's very difficult to assist you. Please try to post in complete sentences with punctuation, capitals, and correct spelling. Toshiba does NOT provide any direct support in these forums. All support is User to User in their spare time.

HT1695 Ipad will not find wireless networks that it used yesterday, but MacBook Pro still finds and uses these networks.

Our ipad will not find wireless networks that it used yesterday. Our Mac Book Pro finds them and uses them.
we have reset the cable modem and wireless router, turned off the ipad and turned it back on. Turned wireless off and back on.
but it just spins trying to find networks but finds none.
What do do next?

Settings for wireless network connections are actually stored in two separate places on your Mac, so in addition to the correct advice offered by Jolly Giant, you will also need to delete old network listings in KeyChain Access.
Macintosh HD > Applications > Utilities > KeyChain Access
Locate the name of the wireless network that you want to delete and click it to highlight it
Click Delete on your keyboard
It would be a good idea to go ahead and also delete the current connection as well in case it has become corrupted. This will clear out the old settings and when you next connect to the network and enter the password, the new settings will be preserved.

Leopard upgrade = no wireless networking

I upgraded my Mac Mini (1.83 GHz Core 2 Duo) to Leopard the other day. Took it to 10.5.2 right after the upgrade.
Everything worked flawlessly for about 2 days.
Then the AirPort networking started dropping it's connection. I have a Wireless Router setup right beside the Mini which it now just barely picks up (1-2 bars) and drops the connection every few hours.
And I can no longer browse / see any of the other wireless networks in my neighborhood.
My MacBook which I also upgraded to Leopard is working fine. Full signal strength and can see the 5-10 other networks in my vicinity.
The Mac Mini was also working perfectly fine before I upgraded to Leopard.
I tried deleting the com.apple.airport.preferences.plist as some posts suggest but that doesn't work. I also did a SAFE mode boot to no avail. There seems to be other Mini owners with similar problems but no solutions.
I don't want to revert to 10.4 ... any suggestions?

I'M HAVING THE SAME ISSUE ON AN OLDER POWERBOOK G4 (TITANIUM). I CALLED APPLE SUPPORT AND THEY TRIED SEVERAL CHANGES TO AIRPORT SETTINGS (SUCH AS CHANNEL CHANGES). NO SUCCESS. THEIR LAST WORDS TO ME WERE...WELL, LEOPARD REALLY WASN'T BUILT TO RUN ON OLDER MODEL LAPTOPS. THIS, OF COURSE, IS A CROCK OF S__T AS THE LAPTOP MEETS ALL TECHNICAL SPEC REQUIREMENTS FOR LEOPARD
WHAT'S UP APPLE? SHAME ON YOU FOR NOT ADDRESSING THIS ISSUE. IT'S ALL OVER YOUR DISCUSSION BOARDS BUT YOU REMAIN SILENT. IT'S DISGUSTINGLY ARROGANT.

Can print via usb, but not via wireless network

My new MacBook Pro prints to my Epson RX500 when the printer is connected via USB to the MBP. However, when the the printer is connected by USB to my desktop PC running XP, the MBP does not print to it. I can see disks and transfer files wirelessly among desktop PC, laptop PC & MBP. The MBP finds the RX500 on the network, and has a driver for it. I can set it as the Mac's default printer. When I print, say from OpenOffice or TextEdit, the dialogs seem ok. Sometimes I see the print queue icon wink in and out on the dock. But the document doesn't get printed. The desktop says the printer is shared, and I can print over the wireless network from my PC laptop running XP.
One of the Apple troubleshooting pages suggests that I should have the same driver version on my XP desktop and my Snow Leopard MBP. I don't know how to tell what version the PC is running.
Any suggestions?

Just to be sure - you know that you can't use Epson's "USB-only" driver for printing to a Windows-shared printer?
You must use the Gutenprint driver - that's why Apple included the Gutenprint drivers in OS X.

Macbook will not see wireless network

My new Macbook will not see my wireless network. My Windows 2000 PC, my Ipod touch and my Macbook Pro (jaguar) all see it no problem and work well with it.
I have tried entering the network name manually and it does not work. I have WEP password protection.
The macbook sees and connects to all other wireless networks I've encountered (father-in-law's house, Airport departure lounges, hotspots etc.). The macbook also sees my neighbours networks no problem.
I am confused, please help.

I am having the same issue, a friend visited with his new Mac Mini, running Leopard, and it would not see the wireless network, that 3 other macs (PowerBook G4, iBooks G4 and G3) running Tiger (10.4.11) and Windows machines recognize without problem.
I'm wondering if the issue is Leopard and 3rd party routers or MY router in particular, as I have a US Robotics 5461, and I remember when a previous roommate replaced her G4 iBook, running Tiger, with a MacBook Intel running Leopard, she also had issues connecting wirelessly.
My friend's Mini had no problem recognizing all the neighbors networks (at least 4 or 5) and I'm pretty sure they are not Mac users with an Airport Base Station.
I was hoping to upgrade my G4 PowerBook (once I get it repaired) to Leopard in the future, but I don't want to lose the ability to connect to my wireless network.
Has anyone running Leopard run into this problem and found a solution?

Airport does not detect wireless network; it says problem = [network]"connection timeout"

It is not a problem of signal strength, and my Airport detects other networks. It used to detect the network I want to connect to, for two years. It suddenly stopped detecting the network (which is WPA Personal password-protected). When I select choose other network and type in the password, it won't connect to it claiming "connection timeout."
This happened before. Then after several days, Airport was able to detect and connect to the network I want. Now it again won't detect the network, and this seems permanent short of taking measures to address the problem. Should I try connecting manually to the network, and hodo I got about that? Thank you to anyone out there ho might be able to help.

i have a macmini (OS 10.5) and use a belkin wireless router. When I turn on Mac address filtering on the router I have an Intermittent problem. The airport does not recognize the wireless network. On the network preferences panel there is a message that the airport is using a self assigned IP address. sometimes the message says the airport has no IP address. If I turn off the Mac address filtering and use a WAP password only the network is recognised and connects without a problem. How do I resolve this? I dont have the problem with a iBook using system 10.4. Is turning off the Mac address filtering secur?

New Airport express not finding wireless network

I just got a new AX plugged it in it was recognized did the set up and said to update. It went through the update but the amber light kept flashing. After the update I also lost my internet connection. I have to re-establish my internet connection each time it goes through the update. I have tried the hard boot to the factory specks three times and it still will not recognize my network. I just want to use it to play itunes through my stereo. I am not a computer person so this is very frustrating to me

You will want to configure your AX to "join" the wireless network created by your 2Wire router.
Either connect to the AX's wireless network or temporarily connect directly, using an Ethernet cable, to the Ethernet port of the AX, and then using the AirPort Utility in "Manual Setup" mode, make the following changes:
AirPort > Wireless
o Wireless Mode: Join a wireless network
o Network Name: <existing 2Wire's wireless network>
o Wireless Security: <select the encryption type of the existing wireless network>
o Wireless Password: <enter the existing wireless network password>
o Verify Password: <re-enter the existing wireless network password>
Music
o Enable AirTunes (checked)
o iTunes Speaker Name: <enter desired speaker name>
o iTunes Speaker Password: (optional)
o Verify Password: (optional)
o Click Update to write the new settings to the AX
In iTunes:
iTunes > Preferences... > Advanced > General
o Look for remote speakers connected with AirTunes (checked)

Access connections does not see wireless networks but can connect if you know the SSID

Running a Thinkpad x200 using windows 7 and Access Connections 5.42.
A few weeks ago i was traveling and was connecting to a hotel wireless network.
Could receive email but wasn't able to send email due to hotel port restrictions so long-story short version-- IT staff at hotel told me to connect via LAN. Which i did by simply plugging in LAN line to the thinkpad and to the hotel -- port -- no other changes. have done this a million times at home and elsewhere.
All is well....
until....
I get home and i notice that when i use access connections, it doesn't see any wireless connections (no icons in the radar screen). It automatically connects to my home network and i can use the home profile to connect. Same for any connection that i know the SSID for -- i can't see it but i can connect to it.
But it doesn't show any icons during "find" or find again. It only shows the home icon i am connected to. If i disconnect and try to find wireless networks. It doesn't show any.
So i know
1) radio is working
2) can connect via lan
3) can connect to a known wireless if i know the SSID and either manually configure it or if i have the profile saved
4) i have run antivirus, malwarebytes - etc -- all clean
5) have rebooted, turned radio on off
6) system restore doesn't help
7) all wireless networks are now invisible to radar screen. Have tried this at starbucks, around town - etc -- available wireless network icons are invisible
I'm not sure that hooking up LAN in the hotel did anything but it seems too coincidental. Also seem to recall a thread where this has been known to happen.
Help!!!

First off, it sees the networks. That's good. You reset network settings which usually corrects a number of problems. Let's focus on your home network and getting connected to that.
1. Reboot your router (just power it off for 10 secs). Try to connect. If it works, you are done. If not, step 2
2. Reset your network settings again. However, this time log onto your network by tapping Settings > WiFi > Other and re-entering your network name, security settings, and password.
Check your connection by tapping the blue > next to the network name with the checkmark. If your IP starts with 169.x, then you are connected but your router is not issuing you an IP address. This leads to a couple of additional problem areas - WEP encryption and outdated router firmware.
If you continue to have problems, tell us which router/model, security settings used, etc.

MacBook pro does not detected wireless network?????

Hi! I have an airport express that provides the wireless network for the house. My iMac and iBook as well as iphone have no problem detecting the network. But the network does not show up in the drop down list that shows up when I turn the airport on. When I click on "other" and type in the information that way, the connection times out.
Any suggestions would be appreciated!
Thx!

I have a similar problem. When I set the network to not be closed, My MacBook Pro finds and connects when I return from being away. When I set the network to be "closed", it will not connect automatically (I have checked "Remember and network this computer has joined" & "Remember this Network ") it will not join automatically. However, when I enter the name and password, it connects and all is well. My iPhone will automatically connect regardless of the "closed" being checked or not. Any suggestions? I would prefer to retain the "closed" setting for extra security.
Thanks,
Bruce

Windows XP not recognizing wireless networks

I recently upgrade routers from an old motorola router (about 5 years old), to a new airport extreme. I have a desktop that is running windows 7 and is hardwired into the airport extreme. and i have two ipod's that connect to the airport extreme. However it is my laptop (an old sony viao vgn-fs550) that is running windows xp (sp3) that cannot connect to the airport extreme. I tried the "fix it" solution center from microsoft but it wont download correctly, i get an error, so i tried to fix manually and it still doesn't work, when i go to "view wireless networks" there is nothing there. i got frustrated to the point that i reinstalled windows and for a brief minute i was able to view all the wireless networks in my area, including the airport extreme and the "guest network". but i could not connect to either of them. and then the "view wireless networks" would just vanish.
Is it just that windows XP *****? because if upgrading the laptop to windows 7 will fix this problem I will. But I would still like to know why XP won't allow wireless networks. From what I see online this is quite a problem with windows XP.

As a side note regarding my not being able to view wireless networks using windows xp on my laptop. I am investing in an airport express so i can access the internet on my ipad 2 while traveling. My "new" question is if i can use the airport express to "fix" my problem of my laptop running xp (sp3) not being able to view wireless networks? Would the airport express act like a "new" wireless card for my laptop and therefore will be able to connect to my airport extreme without any problems and without having to upgrade the laptop to windows 7?

Macbook Pro will not remember wireless network

We have two Macbook Pros and are having issues with one of them not finding and then not remembering a particular wireless network. The other one works normally on this network, as do our iPad and iPhones.
The problem Macbook Pro will find a number of other wireless networks in the vicinity, but not the one we wish to connect with. However, when the required information about the network is entered into the Network Preferences, it does see the network and will connect with it, until the computer is shut down. When it is powered-up again, the Macbook will not find it, even though, in theory, it had been told to remember it and that network had been moved up to #1 in the order of priority.
The settings on both Macbooks are the same, so why can one find and remember the network and the other not? What can I do about the problem?
Help please!

Settings for wireless network connections are actually stored in two separate places on your Mac, so in addition to the correct advice offered by Jolly Giant, you will also need to delete old network listings in KeyChain Access.

Not recognizing wireless network

I have a new macbook pro (2 months old). Initially, it had no problems recognizing my wireless network. However, today it is no longer able to recognize any wireless networks. Wireless is still working with my iPhone/iPad. I tried rebooting and no luck. Any thoughts?

Hey jedediah,
EDIT: I read your post again and it looks like your roommate may have turned on Internet Sharing. This means that your computer is like a hub for sharing your internet connection with wired clients.
Check in System Preferences>>Sharing>>Internet Tab, and it should say Internet sharing is off. If Internet Sharing is on, try switching it off, and see if you get some sort of connection.
I'm not sure this will work, but the arrow over your airport icon makes me think it's Internet Sharing.
