TC wifi seen but no longer connecting

I bought my time capsule 1 tb about 4-5 months back and it has worked flawlessly. Last night I taught a photography workshop and wifi was working fine for my presentation on my macbook pro.
Today though, all of a sudden all wireless internet in our house and on my kids ipod touches stopped working. All of our wireless iphones, ipods, and macbook pros can see the wifi that I set up forever ago and the same one we have always connected to, but every time we hit join, it says unable to connect to network.
So I tried restarting the time capsule, and that didn't fix it.
I tried restarting my computer, no luck
I tried setting up a new wifi name with new passcode which the wireless devices also now see and recognize, but same error, unable to connect.
PLEASE HELP!!!! could this be a problem with the TC?

Which computer are you experiencing this on?
There are several threads dealing with (mostly) iMacs + bluetooth keyboards/mice and issues with WiFi no longer automatically connecting. There seems to be some issue that 10.7.3 introduces with these series of macs.
No Apple provided solutions yet, but several workarounds: 1) attach a network cable direclty from modem/router to mac; 2) use the power button instead of mouse/keyboard to wake up mouse; 3) use USB keyboard/mouse (not personally confirmed); use airport extreme/express as a bridge.
Right now it's a waiting game until Apple provides another update. I do recommend going to Apple feeback: (http://www.apple.com/feedback/) and at least voicing your opinion. Calling AppleSupport will do the same, but they'll make you go through the same (likely useless) steps everyone else has done.
Good luck!

I have a MacBook Pro. My mac can detect wifi. But will not connect. I did get connected vis TCP/IP settings but I can't connect to any wifi anywhere. Network diagnostic has a green light for wi-fi and wi-fi settings. Red light for the rest.

Hello NotAppleSavy,
Thanks for the question. After reviewing your post, it sounds like the computer wont connect to networks. I see you have used network diagnostic. I would recommend that you read this article, there are a lot of other things you can do in this article that may be able to help you resolve or isolate the issue.

My Apple TV recognises my wifi network but will not connect to it, when I enter the password

Help please - my Apple TV recognises my wifi network but will not connect to it, when I enter the password - it just says 'there was a problem connecting to the network - check your settings and try again (5).' What should I do next?

people repport that apple products in general I believe have problems with support for the outdated encryption type called wep encryption which is also pretty useless and easy to break
if you use that try disabling it or changing to wpa encryption
if you use MAC address filtering in your router then you need to add the appletv's MAC address to the positive list

Just got new ipad2 and can't connect to internet...recognizes wifi network but won't connect

just got a new ipad2...recognizes wifi network at home, but can't connect to internet...help???

I just had a similar problem. Both the ipad 1 and ipad 2 in my household quit connecting to the network even though it seemed to recognize it. if you think it is recognizing your network, just not connecting, check to see if bluetooth is turned on. i had to turn bluetooth off and then manually enter the DNS number.
My solution also came after I re-started my network and reset all the settings on the ipad2. The DNS number then showed along with IP submet Mask and router. I used that dns number to enter into ipad1 after turning bluetooth off on it.
Totally unscientific fix that may have been more coincidental than correct but you might try it. BTW--no idea how bluetooth even got turned on to begin with.

My Apple Tv is connecting to the Wifi network but is not connect to the internet. So when I look for it on my Airplay it doesn't come up. I have 3 other ones already working on the network and they are all fine.

My apple TV is finding and connecting to the Wifi network but then says it is not connected to the internet and then I cannot find it on the iPad through airplay. I don't want it connected to the internet (as in www.) because for the use I have I only need to use the Apple tvs locally in a sports hall as scoreboards. I have 3 others working on the same router and they are working fine (as of yesterday)
On my screen I see (obviously not written like this)
network connect- yes
signal strength- fine
Ip address- fine
DCN- fine
Activation- Failed
This is the only negative I can find and the statement that the Apple TV has connected to the wifi but is not connected to the internet.
Where has it gone wrong for me. Please help

It is not properly connected to the network.
Make sure location is set correctly
DNS should be on auto (settings - general - network)
Try ethernet
Signal strength on device won't account for issues, you would need a network report from istumbler, netstumbler or similar. This will show accurate signal strength along with noise and nearby networks

I'm at a loss. and I've googled my little heart out. Any help would be appreciated.

Welcome to the forums - and thanks for a great initial post, all the needed information seems to be here.
Specifically, the following error from wpa_supplicant will most likely be best to dig into:
wlp3s0: failed to initialize driver interface
I see several results of this error in a google search, but none of them quickly translated into solutions yet. To get some more information on it, could you run the same wpa_supplicant command, but with the verbose debugging flag "-dd" and post the ouput here?
I don't have a intel wireless card, so I don't know what the diagnostic signs are for the problem addressed in the wiki, but you may want to try the modprobe options shown in this section of the wiki.
EDIT: there is a similar but unresolved thread on these forums here which points to using the -D flag for wpa_supplicant to specify other drivers. I was thinking this too upon my first reading, but I don't fully understand what these are so I was reluctant to suggest it. It certainly can't hurt anything to use the command in the wiki to see which drivers are available, then try each one.
EDIT 2: and this thread seems to indicate that the -D flag driver specification is the right solution. So start here with the -D flag and only if that fails follow up with my initial debugging suggestions.

AE is green and seen but can't connect PPPoE

My ae light is green, the network sees it but can't connect to the net. The isp is fine if i plug the wire into the machine, it works. The settings for the airport are identical to the wired. i've downgraded from 6.2 to 6.11 but still no connection. the problem seems to be that the airport express either can't sync or won't connect to the isp. I've also tried powering off the ae and modem in different orders powering on each one in order with the computer last to no avail. i'm running 10.4.2. help pleez

Glad to hear you got it working!
Firmware version 6.2 has well-known problems with ISPs that require use of the PPPoE protocol, and downgrading to firmware version 6.1.1 is what solved the problem for you. Firmware version 6.2 is no longer available from Apple's web site, but many people got it previously as part of the Airport 4.2 update where it lurks as a time bomb waiting for people to finally give in to the Airport configuration utility's request to upload that update to their Airport Express.

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

I have just purchased an ipad 2 (already have an inpad1) and after syncing through itunes it will not conncect to my home wifi connection. The first ipad connected immediately when bought. this one indicates my wifi address but states not connected.

What make, model and version router do you have?
Is MAC address filtering turned ON in your router?
Do you have a limit on the number of connections set in your router?
What type of security are you using, i,e, WEP, WPA, WPA2?
Have you tried restarting your router? (remove power for 30 seconds and restart)
Does your iPad 2 work on any other networks? Starbucks, Borders, etc

Resetting Time Capsule - network is OK, but no longer connects to internet

I've set up my TC in the past and it's worked fine, but periodic printer or router updates have caused problems and I think I need to completely reset it.
My setup is an ISP-suppled Orange Livebox Mini router connecting to the internet, an iMac plugged in by ethernet (connects to internet OK) and my TC connected to this router by ethernet. My MacBook Pro then connects wirelessly to the TC network. This setup means I don't need to have two wireless networks, I can disable the Livebox router's wireless network and use only the Time Capsule wireless. However, that's not working. I can create a wireless network with my MacBook Pro but the TC is unable to get an internet connection despite being connected by ethernet to the router. I think I need a total reset but even when I do a manual reset by sticking a pin in the tiny button on the back of the TC, when Airport Utility finds the TC to recreate a wireless network, I find the old settings. I feel this is, or should be, simple stuff as I managed to set it up before, but this time it's just not happening. For a long time I thought this was just a problem with wireless settings on my Lexmark printer and waited for the Apple/Lexmark updates to come through, but now I think my TC settings need to be flushed out. One thing that looks odd to me is the IP address on the TC. It's 169.xxx.xxx.xxx, I thought it should be nearer the range specified by the Livebox router, something more like 192.168.x.x
thanks.

Oh joy and happiness, I solved it myself, and I owe it to the community to give some details for the benefit of anyone with the same problem searching on terms like Orange Livebox Mini.
I solved it by racking my brains till inspiration came - that it was a very very well hidden setting on the router itself that was the problem, nothing to do with Time Capsule. I had called Orange to fix this before, but had forgotten that this little setting needs changing from its default every time you reset the router.
When you have to reset your Orange Livebox router, they more than likely won't ask about your entire setup, they will get one of your computers working by connecting it by ethernet to the primary ethernet port, numbered '1' on the back and with a red stripe next to it. But there are two, number 2 has a yellow coloured stripe and if your main computer, in my case the (desktop) iMac right next to the router goes into ethernet port 1, you will want to connect your Time Capsule into the second, yellow ethernet port. However, that port is not set to work automatically for anything to connect to, it's set up for digital tv. You need to go into your Orange admin page for the router, found by going to 192.168.1.1 on your browser and logging in (remember 'admin' is the magic and default password to get you in. If you have to do a manual reset because you changed and forgot your password, the magic word gets you back in). Once logged in, select 'services' in the menu on the left, then 'digital tv' and then select the 'disable' button. I know, you'd never have found it and never have guessed that's what you need to do to open up the second ethernet, but you now have two ethernet ports into the router and your TC goes into the second work.
Also wanted to say that my TC has actually been flawless in its performance. Not always easy for simpletons like me to set up, but the hardware has always worked. Printer updates and, I think, Apple OS updates remain a problem as they can throw the printer off, but I must remember to keep my nerve - TC is basically right on, it's just the various different ways to get at it - Network Diagnostics, Airport Utility that confuse me.

Can see the wifi network but can't connect to the internet

Hi all!
I've begun using a new ISP a few days ago, and while my desktop pc works just fine (ethernet), I seemed not to be able to connect to internet with my mac (either ethernet or wifi) even if I could see the wireless network. I thought it was an issue with the ISP and not with my mac, until last night when I tested it at a friend's house and bling..I couldn't connect there either!
All seetings seem fine both for ethernet and airport. Today I've verified and repaired disk and permissions. I've also created a location specifically for this network (while I've always used automatic before) since the ISP suggested to do so.
I've been able to use the internet, both wifi and ethernet, until literally two days ago on all sorts of different wifi networks.
Any ideas folks?
Thanks,
D

Hi! It's been a while but here's the latest update on the case.
(And yeah,I've been struggling until today to find a solution...Danny's personal advice: don't move to Italy if you don't wanna get lost in a Customer Service nightmare...)
Anyhow, it turned out to be as simple as this:
1) Create a location dedicated to the home network.
2) Insert PPPoE user name and password given by ISP.
3) Connect.
4) Browse wirelessly.
...I feel a little dumb overlooking this option....but, I still have some doubts reg the procedure.
Why did I have to create a dedicated location?
Why do I have to use PPPoE rather than DHCP?
Thanks mate,
D

Wifi bars, but no Internet connection.

After two weeks of using the new Ipod Touch 4g, the wifi suddenly stopped connecting to the internet. All other computers and my xbox has working internet except my Ipod Touch. It says that the Ipod is connected to my network and shows bars, but when I try to access Youtube, Safari, or any other application that requires an internet connection, it says that there is no connection to the internet. Both Wifi and Bluetooth addresses appear in the About section under General in Settings also.
I've tried the first three suggestions in
http://support.apple.com/kb/TS1559
, which includes reseting Networks, data, and the whole Ipod itself.
Any suggestions on what should I do?
