Time Capsule won't connect to the internet

I have a similar problem with my TC. My guess is the problem lies in the DHCP code. My AE works just fine as well, no connectivity problems. Talked with Apple and though they did not have a fix or work around they did mention that other users are having similar issues. If that is any consolation.

As a first attempt - power down your cable modem for more than 30 seconds - unplug it if possible.

Turn your TC off.

Plug your modem back in and after it is ready - power on the TC.

This worked for me. The problem is the cable modem does not recognize that a new device has been attached some times.

Alternatively, your cable provider is caching the MAC address of the AEBS.
In this case, you might need to power your modem down overnight or call your cable company and ask them to flush the caching entry.

Same problem here.

Just downloaded the airport utility update & still no fix.

there are 5 macs in this house all connections to the internet is great but when trying to connect on my g4 desktop with airport it says that connection times out or invalid password when infact it is the correct password.

ive tried everything even resetting the nvram at boot.

ive tried manually inputting dhcp info still no connection.

ive erased keychains and network profiles. still nothing.

i can access the TC and share itunes libraries but just the internet wont connect on this one specific machine. !

whats the answer to this glitch?

HELP.

Open your airport utility and go to manual mode, then click on the internet tab. If you are getting an ip of 169.254.x.x then the Time Capsule is working just fine. It sees that there is an Ethernet cable connected but it is not getting an ip address from the modem, and is assigning a self assigned ip address.

Its a problem with your Cable or DSL modem. Turn off both the modem and the Time Capsule. Wait for about 5 minutes then power on the modem and let it power on all the way. Then power on the Time Capsule wait up to 5 minutes for it to get a green light.

NOTE: This will happen if your modem is using DHCP to distribute IP address to connected devices. If you have to use a manual IP address then you need to get that information from your ISP.

Thanks sasheroni

ive tried that.

still no luck.

all other machines are able to connect wirelessly to the internet.

this particular one can mount TC and read the itunes library but just not the internet.

i know my airport card is working. but the communication with internet is being blocked somewhere.

all information is correctly inputed.

any other ideas?

I'm " happy' to know that I'm not the only one with this problem. My TC arrived one week ago, but there is still no Internet connection possible. Yesterdays update of Airport utility doesn't make any difference.
My Linksys router doesn't have any problem with the Internetconnection.

At this moment the only function of my TC is backing-up via Ethernetcable.

I'll try the unplugging trick tomorrow. Other suggestions are welcome!

not me.

i get either :

A: password incorrect

or

B: connection timeout

what is the real deal? what is really going on?
can my airport card be fried from all the wireless backing up? (134 gigs)

Hello Frederic,

I was having the same problems listed here. I was trying to extend my Airport Extreme set up with a Time Capsule. I had actually got the time capsule going, but could not get the Airport Extreme to play nicely. I connected an ethernet cable and changed some setting, still no luck and then the Time Capsule would only connect via ethernet, ie unplug the cable... no internet connection. Now I'm not saying that everybody has had the same problems, this worked for me... you never know.

Go to Network in System Preferences and make sure that Airport is at the top of the list. It will try to connect to the top item first. My top item was Built in Ethernet. To change the setting click on the padlock, enter your code and then click on the cog and select Set Service Order..., you can then drag and drop Airport to the top of the list.

I'm sorry if this is too simple for this discussion thread, I messed around for quite some time, in the end this worked for me... I hope it works for you too.

Cheers

I will tell you what i did with my TC after it did not work following the regular "plug and play" plan . You have some questions when u set up the TC . One of them is regarding the type of connection u have . First i choose the simple one- the first one - i forgot what exactly says and it did not work at all but the important one was regarding my PPo type/connection , the second one in list ( u have 4 or 5 questions ). I choose that one cuz I remembered I had a user name and password provided by verizon .

So if you have something like that from ur internet provider, try it.

It worked for me .

If I did not explain myself accurately ask me for more details I will try to provide .

Hope it works .

OK !

easy problem fix.

i dont know why i dint try this long before.

The whole issue is that my tower G4 had airport not airport extreme.
SO choosing your security option here is KEY !

it defaults to wep options so i didnt even think of trying others since everything else was working.

but changing it worked.

so anyway just do this:

choose manual settings in you airport utility.
go to internet tab.
choose wpa security settings and then put in your exact 13 character password.
then update. and voila everything should be kosher.

thanks

Hi.
I am dealing with similar problem.
I bought my MacBook this February and TC in March
For the first month or two it was fine but then it started doing random stuff.
Every second day my AirPort keeps loosing signal and when I click on the icon it shows me that my network is there but when I select it it either comes up with the sign "invalid password" or "connection timed out".
Also it sometimes starts behaving even worse - Scanning, On, Scanning, On... and keeps doing that for as long as you leave it running.
At the same time my girlfriend can connect using her PC no problems...

My time machine was working fine until last week...
Now every time it starts backing up the whole screen goes dark and the sign comes up "you need to restart your computer. Press and hold the power button for several seconds" in four languages!!!
PLEASE HELP!!!!!!!!
Do I have a problem with AirPort or Time Capsule?
Please help!!!
It is driving me insane!!!
