Airport Extreme: Does it need to be connected to the internet to function?

I'm dealing with some wireless connectivity issues and I'll post a new thread once about that once I confirm that the issue isn't originating with my ISP. But for now I want to know:
*Should the AEBS still function to provide wireless connectivity between devices on my network if the cable-modem is unplugged?* For now when I unplug the cable modem, my wireless network disappears.
Thanks for the help!

I am having the same problem as well. It used to work as you would expect but clearly something has changed in one of the recent patches.

Moved AirPort Extreme and now it won't connect to the internet

I have moved my base station on previous occassions with no problems--plug and play if you will.
I just moved it to a new location and while the computers in the house recognize the wireless network with no problems, the base station no longer successfully connects to the internet.
I have plugged my MacBook Pro directly to my cable modem and confirmed that the internet still works perfectly well to the house. Plugging that same cable into the base station does not bring the internet up.
I've used the AirPort Utility to act like I'm starting from scratch.
I've chosen Manual configuration and replicated all the data from the MacBook's succesful hookup with no success.
I have manually reset the base station and tried the above again, no success.
Any other ideas? It seems too coincidental to me that there could be an actual hardware issue (everything was perfect right before I moved it (I know, I know--that begs the question, why'd you move it? I should say everything was good, except for one room in the house received a weak signal, so I wanted it to be more centrally located)) that arose just as I moved it. My guess is I just need a little tweak to a setting or something but I can't say I understand what all this DHCP stuff is about.
Thanks for your help!

Most cable modems require that you power them off whenever you switch the Ethernet connection from one device to another. The cable modem will refuse to communicate with the new device if you do not do this.
Did you power off/on the cable modem when you switched the connection from the MacBook Pro to the AirPort Extreme base station (AEBS)?
Some cable modems have a reset switch for this task.
Some cable modems have an internal battery which must be removed to do this reset.
Sometimes the cable modem must be left turned off for several hours or even overnight to reset equipment back at the ISP's office.

My PC can connect to the airport extreme but with encryption it cannot connect to the internet my iMac has no issues, any help.

My PC can connect to the new airport extreme I just purchased but with encryption it cannot connect to the internet my iMac has no issues. If I open the airport exteme up and provide no security everything is fine which leads me to believe it is something with the encryption between the two devices. Not sure what step I'm missing here this shouldn't be this difficult.

Sorry, I should have been more clear. I am asking if the DNS IP addresses, not the IP addresses assigned by the DHCP service, are the same. DNS is like the Internet's version of the Yellow Pages. Your ISP typically will provide them to you or you can elect to use those provided by another source, like OpenDNS.
DNS is the service that translates a website's URL to its actual IP address so that you can access it. I am just trying to rule out that the PC is not configured properly with the correct DNS IP information.
The other thing to check is if the PC is configured to use a Proxy service. By default, it would not be.
Finally, what is the make & model of the PC. More importantly, if the PC is using either a PCI or USB wireless adapter, what is its make & model?

Ethernet? Does TC need to be connected to the internet?

Not sure what the story is there. I just need TC as an external hard drive. Don't care about connecting it to the web. Do I have to connect it to my modem anyway via ethernet cable? Is that the only way my mac will see it wirelessly?
Firewire is looking good right now, I've wasted 4 hours trying to set up TC and it's still not working. It did start backing up, then stopped half-way and never resumed. I think I will need to erase the TC disk and start again (if I find a way to do this). Looks like another piece of c@ap that just doesn't work.

I have TC setup wirelessly on my network. I am using an Airport Extreme Base Station as my router and the TC for backup. The setup was straight forward as I did not use the manual method (tried it first and had problems). Once configured, everything worked well with the backups except that the TC keeps loosing its network connection. Only way to fix is to unplug/plug power cord.
Hope Aple fixes this soon!!

Does TC need to be connected to the internet to backup to?

I have a network of 3 airport extremes but I would like the TC to not be assessable by the network. Just wifi backups...

TimeCapsule does not require an internet connection to backup computers which are joined to it's wireless network.

My nook app continues to state "Please be sure you have internet connectivity, then try again." I am currently connected to wifi and it seems that all my other apps that need to be connect to the internet are properly working. Help!

My nook app keeps telling me "Please be sure you have internet connectivity, then try again." I am currently connected to wifi and it seems that all my other apps that need to be connect to the internet are properly working. I have turn off my phone, signed off my wifi, installed a new app, but nothing is working. My friend is having similar issues. My phone is up to date. I even tried taking off the wifi in hopes that it could just connect to the 3g but nothing. Not sure if anyone else is experiencieng this issue or knows what I can do. I think that it may be an app problem that needs fixed, but not sure. Help!

Maybe its a Viber problem. As that is not an Apple product, why don't you try and contact the developer?

HT1657 Do I need to be connected to the internet to watch a rented movie once it is downloaded?

If I rent a movie from iTunes and I download it to my phone. Do I need to be connected to the internet to watch the movie?

Some posts have suggested that you need to be online when starting to watch the film - so if you want to watch it somewhere where you won't have internet then you could watch a few seconds of the film when you do (you have 24 hours if you are in the US, 48 hours elsewhere, from when you start watching a rental until it expires)

"Your computer does not seem to be connected to the internet." when trying to sign into Lightroom Mobile

I want to connect Lightroom 5.5 with Lightroom mobile. I click on the identity plate in Lightroom and select "sign in". A window opens saying "connecting...". Eventually the message changes to "Your computer does not seem to be connected to the internet." My machine is a Windows 8.1 PC and I already tried to solve the issue by allowing LR through the firewall.

I just found a solution:
- Close Lightroom
- Rename your .lrprefs file to e.g. .lrprefs.old
- Launch LR
- Sign in
- Close LR
- Delete the newly created .lrprefs file
- Rename your previous .lrprefs file from .lrprefs.old to .lrprefs
- Launch LR again and sign in

Trying to open Premiere elements 12 for the first time even though I had it loaded for a while. It gives me a message that I need to be connected to the internet (which I am) or that my clock is off (it is correct). Any suggestions?

First we need to check , whether the LAN settings is set to detect settings Automatically or not.
Follow below steps .
1)Open Control Panel and then click on the option "Network and Internet" .
2)Click on Internet options, click on 'Connections' tab.
3)In the 'Connections' tab, select 'LAN' settings, you will be able to view the Local area network settings box.
4)Check the box-"Automatically Detect Settings" and then "uncheck" all the other check boxes like 'Use automatic configuration script', 'Use a proxy server' , Bypass proxy server' ,then click on ok button .
5)Click on "LAN settings" button again , make sure "Automatically Detect Settings" is the only option selected, keep the LAN properties window open.
Then launch Premiere Elements 12 and try to sign in.
If the settings were already set like that or you face same issue after signing in , let me know

Extreme (b/g/n) can't connect to the internet

my iMac has no problem seeing my airport extreme (b/g/n), but I can't connect to the internet.
I have tried soft / hard reset & factory reset as well, none of them worked. The extreme just keep flashing its amber light.
On my iMac, I have full signal bars, so recognizing the extreme is not a problem. The only thing I find strange is that the IP address (the one assigned by my ISP) is 0.0.0.1.
I tried connecting through an Ethernet cable and it didn't have any problem, so it's not my ISP. The only thing I can thing of is that the extreme somehow is having trouble recognizing that assigned IP and that's why I can't get connect to the internet.
Anyone suggestion? Is my extreme broken? If so, can it be fixed? Please help.

Problem solved!
Every time, I feel so stupid once I find out the answer to my problem.
Here it is from another post by 'dwbird':
"Solution: I found that the service name (optional on the setup) may be optional but if your service doesn't require it and you put a service name in the block it prevents the system from working, hence cannot find the PPoE Server and also cannot get an IP address assigned. Guess the moral of the story is that if it is not absolutely required don't fill in any "optional" blocks"
I deleted the name of my ISP and everything works just fine, the stupidest thing is that this is not the first time...
maybe Apple should consider putting a reminder/warning underneath this OPTIONAL service name field.

Aiport extreme dual band base station not connecting to the internet...

I just bought the aiport extreme the other day, i'm having a lot of trouble connecting to the net.
my setup:
ADSL 2+ modem connected to the airport which than connects to my MBP.
I have no problem connecting to the internet when i hook up my MBP to the dsl modem, but for some reason the aiport is not letting me trough saying that, today it managed to do a software update... how i dont know could this be a DNS problem? and how do i fix it?
Many thanks!!!

Can you tell us whether your "modem" is a simple device with only one ethernet port or is it a "gateway", which is a combination modem/router with 3-4 ethernet ports?

Airport Extreme Base Station and Multiple Computer Access to the Internet

I have my IMAC connected to the internet via the Airport Extreme Base Station. When I am able to connect, my son's MacBook cannot. If I preform network diagnostics and reset the base station so he can connect (which appears to be luck on my part), I can no longer connect. When I first set this up, I had it working with all computers in the house. I tried to expand the system to boost the signal in our house with the airport express units. I have since removed them and started over, but still cannot provide internet access to more than one computer.
