Can see network but won't connect

I have three computers using an Airport Express base station. They've worked just fine until this morning, when I bumped up security by setting WPA/WPA2 Personal.
Since then, the Power PC G4 (OS X 10.4.11) can see the base station's network, but will not connect to it.
I've done multiple restarts, verified permissions, unplugged and replugged the base station and also the cable modem. Nothing has worked.
Please help.

Yes, if I set "Security" to "None," the G4 can connect. But I set it up after I found my next-door neighbor's shared files folder listed on my network this morning. He's an OK guy, but it made me aware of how vulnerable my network is.
My firmware is version 9.52. I've prowled the Apple site looking for an indication of whether that's the latest, but couldn't find one. My "Software Update" says everything's up-to-date.

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!

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

IPad 2 can see wifi but doesn't connect ... What's going on???

iPad 2 can see wifi but doesn't connect ... What's going on???

A few more things that you can try.
Turn WiFi off - restart the iPad - turn WiFi on again and then try to connect again. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button. Try to join again.
Go to Settings>General>Reset>Reset Network Settings. Then select your WiFi network again and try to join again.
Go to Settings>WiFi>Tap on the arrow next to your network name and then tap on Forget this Network in the next window. Then back out of the setting and go back to WiFi and let the iPad find your home network and then tap on the network name and try joining it again.
Do the same thing as above except don't tap on Forget this Network - tap on Renew Lease at the bottom.

Laptop sees Photosmart on network, but won't connect

I have a Pavilion dv4 with Windows 7. I have a Photosmart C4795. My printer used to be hooked up to my desktop, but my HP Desktop has crashed and it's trash. So now I'm trying to hook my laptop up to my printer on the network. For two days, I was able to connect and download with no problems, but my laptop would never print. Wouldn't even do a test page. Uninstalled and reinstalled at least 10 times. I ran the scan doctor and it said there was nothing wrong with my printer, but it wouldn't print a test page either. It then had me do an internal test page and that one work, so it diagnosed that the software was bad.
All of that was yesterday. NOW TODAY, I uninstalled and reinstalled the software. It's the most up to date software and drivers from the HP Support page. Now, my printer recognizes that the printer is on the network, but won't install the printer. It did the diagnostics, then brought up the screen where it showed my computer on the left, modem in the middle, printer on the right. It gets about halfway through setting it up, then quits and says it can't complete. I ran the scan doctor again and it says that the full software version is not installed. I JUST downloaded it from the website and installed it twice and it won't work. The version I download from the website is around 146mb, but when I download it from the scan doctor page, it's over 200 mb. I run that software and it is exactly the same.
I have tried to set it up via usb. It gets to the 7th of the 8 steps, then it won't go any further. Again, the printer is detected, but it says the appropriate drivers aren't there.
I have tried to set up it's own port using it's USB and a different driver, but that gives me an error. Unable to install printer. Operation could not be completed (error 0x000003eb).)
Would someone please help me, and then if I reply with what it is doing next, please respond?
Please help me get through this. Two days now and I don't have a solution.
Just me, friebe13

Hi,

Apple tv is connected to the network but won't connect to internet?

My apple tv 3 is connected to our wireless network but will not connect to the internet. I also cannot turn on home sharing. All the other wireless devices in our house have no problem with the internet. I have hooked the apple tv up to the computer and restored the factory defaults but that did not help. Any suggestions?

have you tried connecting using ethernet to see if it's a wifi issue ?
and have you verified that the required ports are allowed on the network ?

TS1398 my ipad is connected to my wifi network but won,t connect to the internet, i have tried resetting network settings but it still won't work.

my i pad is connected to my wifi network bt won't connect to the internet I have tried resetting network connections. it will connect to the internet from my phone hot spot

Try restarting your WiFi router by removing power to it for 30 seconds.

My mac can see the network but won't connect to the server

I have an intel Imac. The network connect is working but very squirrelly. I see most objects on the network. I can see the server but it will not let me connect.
I go to another mac and I can connect to the server. So I think its my mac 10.7.5 is the OS

Probably nothign to do with your iMac or OS X, have you attempted resetting your router? Also you haven't stated what messages you are getting or any other information. If this is at your work then I'd suggest contacting your IT support person, the connection to your network may be on their end.

Appletv recognizes my wireless network but won't connect to the internet. can't restore to factory settings

appletv won't connect to the internet, but recognizes my wireless network. ip address starts with 169.. somethings not right. never had a problem with appletv and home sharing until the update that required a change in my apple id

An IP address starting with 169 indicates you are not properly connected to your network. Try restarting your router and try to connect again. if the problem persists you may be suffering from interference.

Can see network; but can't get on Web or get e-mail

iMac G3 has decided to change. It's on an office network. It can see all the users on the network, access the servers, access the printers, etc. However, can't connect to Web via IE nor can get e-mail. Any thoughts? I'm at a loss of what to look for.

Hi Paperboy,
Check with your network admin, it may be that it needs a fixed IP address.
Normally DHCP sorts out IP address but every once in a while the network info may need to be entered manually.

Airport card sees networks but won't connect.

I'm not entirely sure why.
Wired ethernet works fine, and our G4 Desktop's Airport card works fine.
Mine, however, is being a bit wonky.
I shut the computer down for the night about a week ago.
Brought it back up and got the "There was an error joining AirPort network *our SSID*".
Fine, sometimes it does that. I wait and it usually works in a few minutes.
Not this time.
We rebooted our Linksys WAP and our Cisco router, no good.
Shut the iBook down again, reseated the Airport card, fired it back up and paid close attention to the verbose boot this time.
Nothing abnormal, no errors.
Still no wireless connection.
I've tried connecting to other wireless networks around us, and we even defaulted the WAP back to out of box state (i.e. it was wide open and not passworded), but nothing. Every other wireless device in the house (G4 desktop, Dell laptop, and a Toshiba tablet) works just fine.
The computer can SEE wireless networks, but it can't connect to anything.
There have been no major system updates recently, and the only program I've installed in the past 3 MONTHS has been the World of Warcraft Burning Crusade expansion. Nothing else has changed, which is what's stumping me.
I'm starting to wonder if:
A) I'm overlooking something incredibly simple.
B) My airport extreme card is dying.

firstly, tesserax, a tremendous thank you for your help. unfortunately, i tried each step you suggested, but the problem continues.
step 1: i have tried and failed to connect to several different networks in a handful of locations (home, work, friend's house, local coffee shop, etc.).
step 2: i have disabled my own wireless encryption as well as the wireless encryption at a friends house, however, to do so i had to use their ibook, as my own either didn't list the base station in the AirPort utility (although it did list the base station in the AirPort status pull down), or it asked for a password even though the base station wasn't password protected (maybe this may add some insight into the issue?).
step 3: i have connected the computer directly to the modem using an ethernet cable and was able to go online - perhaps this means the problem is related solely to the card.
step 4: i moved the the com.apple.networkConfig.plist file and and the SystemConfiguration folder to the desktop and restarted. unfortunately, OS did NOT rebuild the files. instead, i had to go through the network diagnostics to rebuild them manually. while the files were replaced, the problem was not solved.
step 5: i reset the PRAM, but the problem still exists.
step 6: i reset the PMU, but the problem still exists.
i then tried various combinations of your suggestions, including moving the files out of the preferences folder and then reseting the PRAM and the PMU, but still nothing.
after having attempted every fix i could think of (and that was before posting to this forum) i did a full erase and install of the OS. since that's usually the cure all to whatever ails the computer, it's my assumption that the issue is a physical (hardware) one. that said, if you have any other suggestions i will be more than happy to give them a shot.
thanks again,
brad

Mini can see network but can't join

So I have a mac mini that I am using headless and controlling via screen sharing from my imac. When I try to log the mini onto my 'n' network, it isn't able to join. I can see my network in the drop-down airport menu in the menu bar, but when I click on the network, the airport bars in the menu bar icon go 'grey' and I am not on the network.
It seems to be able to get onto my 'b/g' network without problems. Neither network has a password (I live out in the woods with no one around) so I don't think it is a security/password issue.
I have no idea how to go about troubleshooting this. Any thoughts?
thanks

If you must connect your Mac Mini to a "pure" 802.11n network, check out solutions provided by QuickerTek as an alternative.

IPhone 5 Wi-Fi problems: "sees" the network, but won't connect

Hi everybody,
For the past 3 days I've been having sudden problems with my brand new iPhone 5 (version 6.0.2 {10A551}).
It just won't connect to the internet, no matter what I do. It actually "sees"the availble networks, but when I put the password in, it says"Unable to connect to the network".
I tried Resetting Network settings and All Settings, to no avail.
The irony is that I get Facebook notifications, App of the day Notifications, occasional mails, but nothing else. Email sync is erratic, and always with the little round circle where the WiFi icon should be. No Whatsapp, Viber, etc.
I'm totally baffled and equally desperate.
Can anyone help me please?
Many thanks in advance and Happy New Year to all thread readers.
Joyce

Try restarting your router first, turn it off for a minute then back on. then go to settings on your phone, then wifi, tap on the blue arrow to the right of your wifi 's name, then tap forget this network. Then go to the home screen, Then hold the home and off button down until the apple symbol comes up. Then go back into wifi and try to connect.

Satellite L300-135 sees WLan network but won't connect

Well, (new laptop) initially it worked with my BT hub at home... then decided to stop working - recieves no signal or response from the router - even though other laptops in the house can connect without any problem
and now the wireless does not work - ie. I can see the wireless connection but cannot connect.
I'm sure the wireless is not switched off (before anyone suggests so)
I searched for more up to date drivers but nothing seems to work.
Please help!

Hi
First of all you should check if your WLan card has been recognized properly.
I mean you have to check it in the device manager!
Your WLan card should be the Realtek 802.11g(RTL8187B)
Download and install the newest WLan driver from the Realtek page.
Then update the BIOS.
Finally configure all the WLan settings again.
In device manger -> WLan card properties -> Advanced tab disable the power saving settings and check other settings which could affect the connectivity.
Good luck
