Can't set up Aiport Extreme - base station doesn't have valid IP address?

I recently bought an AirPort Extreme to replace my old Linksys wireless router. I am have a cable modem/router supplied by my cable provider and I was using the ethernet cable to connect the modem to the Airport. However, every time I attempt to configure it I get the following message: "Your Apple Wi-Fi base station does not have a valid IP address." I tried to call Comcast to see if there is something I need to get from them, but they want to charge me ~ $45 to enroll me in wireless tech support! Anyways, I'm at my wits' end - please help if you can!

Hello MrRuminator. Welcome to the Apple Discussions!
Each time I attempt to connect to the internet with the AirPort Extreme I run into "Base Station does not have valid IP address -- make sure your base station is connected to your broadband modem..." error. What's odd about this is the fact if I simply plug the ethernet cable back in the older Airport (like right now), I'm able to access the internet once again. Have tried powering off and resetting everything, to no avail.
It still sounds like your modem is not "recognizing" the new 802.11n AirPort Extreme Base Station (AEBSn).
Try the following, in order, until (hopefully) resolved:
1. If the modem has a reset switch, use it to reset the modem. Wait at least 5-10 minutes for the modem to initialize.
2. Remove power from the modem. If it has a backup battery, remove this as well. Wait 5-10 minutes. Replace the battery, and add power back to the modem.
3. Perform a complete power recycle of your network components as follows:
Modem/Router Power Recycling - Quick
o Power-off the modem, AEBSn, & computer(s); Wait at least 5 minutes.
o Power-on the modem; Wait at least 5 minutes.
o Power-on the AEBSn; Wait at least 5 minutes.
o Power-on the computer(s)
If this fails to get the modem to "recognize" the Internet router, then try the "Full" version.
Modem/Router Power ReCycling - Full
o Power-off the modem, AEBSn, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
o Power-on the modem; Wait at least 15 minutes.
o Power-on the AEBSn; Wait at least 5 minutes.
o Power-on the computer(s)
4. Contact your ISP to have them perform a "modem reset."

If I buy an Apple Airport Extreme Base Station and I have an Optus Cable internet. Do I really need an Apple Care Protection? or I don't have to?

Hi I'm from Australia.
If I buy an Apple Airport Extreme Base Station and I have an Optus Cable internet. Do I really need an Apple Care Protection? or I don't have to?

Any specific recommendations for a standalone ADSL modem though?
Always a good idea to use the modem that your service provider supplies or recommends....often free....since you know that it will be supported in the event of connection difficulties.
I have made the mistake of choosing the "best" modem based on test reports....only to find out later that the ISP would not offer any support when I was having connection difficulties.
The ISP blamed the modem. The modem support folks blamed the ISP.

Ibook G-3 with old airport card can't see New Airport Extreme Base Station

I have been trying for a week now to get my G-3 ibook set up on my Airport Extreme Network. No matter what I do, I can't sign on to the network. When I put in the password I get an error message 3151. I have no idea what this means. I have read everything, restarted base, changed network password, trashed all airport and prefs on G-3 and reinstalled. Although my network shows up in the control strip, it doesn't show in the setup assistant. Please help if you can, I'm about to go crazy! Thanks.

Dear Duane, I did have 802.11b configured, but I had the WPA instead of WEP enabled. When I reconfigured my network, the clamshell was instantly able to join and use the network. I have many many questions about how to use the network to allow both computers to communicate, but I'll read up on it and I'm sure the answers will be there. You saved me $240.00 for the 1st hour and $160.00 for anything over that Techserve was going to charge me to come and set it up. I can't thank you enough. Everyone tells me not to waste money, but to save for a new ibook with System X, but I love my old clamshell and I'm going to get it a bigger hard drive so it can be upgraded to run OS X. It's the old 4 Gb one. I can't thank you enough for your solution! Now I can work on the laptop in my bedroom! I love Mac stuff and I knew the Extreme base station would work, regardless of what all the posters have been saying.

Can I use an Airport Extreme Base Station from the USA in Europe ?

A friend of mine gave me an Airport Extreme Base Station from the USA to Germany. When I hook it up to my PB by ethernet cable the Computer can't find the Base Station at all. If I use my Sonnett Aria Extreme PCI card it finds the station but in the pop-up menu asking in which country I want to use the airport station it only offers North and South American countries. How do I go from here and why is my PB not finding the station when I'm using cables ? Has it something to do with different models for different countries ? Any idea ? Thanx

Here you go ...
Changing the Radio Channel on the AEBSn
Either connect to the AEBSn's wireless network, or temporarily connect your computer directly (using an Ethernet cable) to one of the LAN ports of the AEBSn, and then, using the AirPort Utility in Manual Setup, check these settings:
AirPort - Wireless
o Channel: <Use Automatic or select a preferred channel>

PS3 can't see new Airport Extreme base station

I replaced my old airport extreme with the latest one, but now my PS3, which is on another floor, cannot see the base station, and the new base station has a lot less range than the old one. With my old one I could sit out in the back yard with my laptop, and the PS3 picked it up right away over our wireless network, but now, nothing. My laptop connects okay, just can't go very far. Nothing has changed except the base station itself. Please help.

Hello Uri. Welcome to the Apple Discussions!
A few things I would suggest that you try to see if either or both help with the PS3's connectivity to the 802.11n AirPort Extreme Base Station (AEBSn):
o If currently enabled, disable the Guest Network.
o Use a separate Network Name for the 5 GHz radio. Make sure that the PS3 connects to the 2.4 GHz radio's wireless network.

Airport Utility can not find air port extreme base station

I am running XP home on my computer and have an air port extreme base station connected to it wired. I have no problem connecting to the internet yet more times then not the air port utility can not find the base station. On occasion it will find it but most of the time it can not. Rebooting does not help.

I recently purchased one of the new Airport Extreme base stations and after carefully reading the instructions; I first installed the Airport Utility 5.5 that came on the CD onto my MacbookPro. I then connected the new base station to my macbookpro via Ethernet and power it up. I copied a previously saved configuration onto it. All my printers, IMAC and macbookpro were able to connect.
I then used my older base station and my airport express to extend the N and G networks through the house. My problem was (1) the new Airport utility would consistently lose the older extreme base station and the airport express, (2) An my HP printers keep losing the wireless connection to the new airport extreme base station. The only resolve was to consistently restart the new base station, after which (1) the new airport utility would see the older base station and express again and (2) the wireless connection to the printers would be restored.
After about a week of this, I removed the new Airport Extreme and replaced it with the older extreme (802.11N DRAFT) and de-installed the Airport Utility 5.5 and re-installed Airport Utility 5.4.2 and everything works fine.
Has anyone else experienced any problems with the newly released Airport Extreme (fully 802.11N) base stations and Airport Utility 5.5?

Setting up airport extreme base station with Mac and PC

I have an '02 iBook with an airport card installed and an airport extreme base station. my roommate has a PC and has the DSL connection in her room. i want to wirelessly network my iBook via the airport base. how do i do this? (my base was given to me without any manuals/disks etc)

Your Netgear wireless router is your network's base station. Your parent's PC will not be "serving as a base station" - its presence on the network isn't at all relevant to what you want to do.
To connect your G5 to the Netgear wireless router's network - click on your Mac's Airport menu, click on the name of your Netgear wireless router's network (it will appear in the list when you click on the Airport menu), and enter the wireless network password (if applicable) when prompted by the MacOS. That's is - you are connected!

Have iMac, MacBook Pro, & Aiport Extreme Base Station - WHAT ELSE?

I have an iMac, just bought a MacBook Pro (both have airport cards), and will have my Airport Extreme Base Station delivered soon.
Do I need to buy anything else (i.e. cables) to setup my wireless network (iMac, MacBook Pro, Printer, Internet, Email)?
Thanks for the information...

Dear MacChad,
What you will need is an Ethernet cable that connects your Airport Extreme Base Station to your "Internet connection device".
What this "Internet connection device" is will depend on how you are connected to the Internet with your ISP. Typical ways would be via Cable modem (supplied by your ISP in most cases), or DSL modem (supplied by your ISP in most cases).
Hence, the Ethernet cable will also be found with your "Internet connection device". This is the same cable that this device supplied for connection to your computer.
Note that Wireless LAN is not secure, therefore it is recommended that you take all precautions to protect your network. Especially if you do not want to share it with your neighbours.
Some suggested steps are:
1. Create a "Closed Network".
2. Assign a password to your network
3. Create a generic SSID (aka. Network name). One that DOES NOT reflect the fact you have an Airport Extreme Base Station, any Macintosh products and your name.
4. Turn on WPA encryption at the minimum. WEP encryption is too weak and is useless.
5. Utilize MAC address filtering, but entering the MAC address of both your iMac and MacBook Pro into your Airport Extreme Base Station's MAC Filter list.
I hope this helps.

Can I use the Airport Extreme Base Station with my already existing D-Link router to increase signal strength?

I already own a wireless router that I would like to keep. Could I use this Airport Extreme Base Station to improve that signal strangth to my room from the living room or to the basement? Would I have to hard-wire both the Base Station and my existing router? You probably have read this question more than once, and I have read some questions of this product too, but for some reason these Apple products I have some trouble with.

Could I use this Airport Extreme Base Station to improve that signal strangth to my room from the living room or to the basement?
Yes

Yes

DrayTek Vigor 120 + Airport Extreme Base Station? I have queries.

Ok, so my 3 or 4 year old USR 9108 router went down today-- again. I'm fed up and want a new one. It dies on me once or twice a month. It has decided it doesn't like my powerline adapters lately. and I'm fed right up. I run an internet radio station and what I need is stability.
At the moment, I'm thinking of setting up a DrayTek Vigor 120 ADSL modem (modem-only) with the Airport Extreme Base Station for my router. (I already have an Express on my network.)
First of all, can anyone please comment on whether they have this set-up and whether it's solid? I've heard good things about both of these devices, and I need something that's not going to flake out as regularly as my USR has been doing of late. Rock solid is a good thing for a 24/7 stream.
Second, can I just confirm a few questions that I think I know the answer to, but want to be sure before shelling out?
I am in the UK using an ISP that uses PPPoA; so I need to be sure the modem has a PPPoA to PPPoE bridge in order for the Airport to talk to the outside world. (Right?). I gather the DrayTek will do this. Will it therefore be just a question of setting the Airport to connect via PPPoE and then entering my ISP login settings in Airport Utility?
I need a setup ideally that, like the USR, will allow me to assign IP addresses manually to some machines or devices on my network but allow DHCP on other things (like my iPhone). It's particularly important that the radio stream should have a static IP. I gather, from having a play with my Express's settings, that I'll be able to accomplish this either directly or by DHCP IP-reservation. Directly would be preferable. Therefore, if I, e.g., assign my computers an IP address on their local network settings and then just shift the Airport's DHCP range so that it starts with (say) 192.168.1.10, rather than, 192.168.1.2, will the Airport be happy with that?
I also need port forwarding / port mapping. This should be o.k., right?
Thanks for help, people.

I'm running a very similar setup here in the UK. I use a Netgear DG834 rather than the Draytek 120 which I was looking at. I use a Time Capsule connected to the router which is in half-bridge mode and this allows me to connect using PPPoE, which is possible on the BT ADSL network, which I didn't know before! - there's no need to get an expensive PPPoA-PPPoE bridge. I guess the Draytek would do an even better job than the Netgear, but mine was the free solution
I use the TC to give out addresses to a network of various kit, with one fixed IP for a specific device. I find the TC and my airport express very easy to set up and run, if slightly light on the details of what's actually going on. That said, if it doesn't work, then they're probably broken!
Nothing you've asked for is out of the ordinary / impossible on the apple kit.
Hope that helps!

Do i need an extreme base station if i have an airport express?

I just got an Apple ibook G4 laptop through a program at my school which is Airport ready. I'm not really that computer smart. At home we have 1 ethernet cord attached to a different computer but I want to set up a wireless connection in my room just for my laptop. Can I do that with just an airport express base station, or do I have to have a stationary one first? Would it be easier just to buy the extreme base station even though it costs more? Also, how does the express work? Do you just plug it into the wall, or does it have to be connected to some sort of phone jack, or what? Again, not computer smart at all. HELP!!!

bcbandtiger, Welcome to the discussion area!
Since an AirPort Express (AX) won't support a wired (Ethernet connected) computer, you can't solve your problem that way.
If your only goal is to create a wireless network for the laptop, you need either the AirPort Extreme base station (AEBS) or any other inexpensive 802.11b/g compliant wireless router. These will provide an Ethernet port for you wired computer and create the wireless network for your laptop.
Do you just plug it into the wall, or does it have to be connected to some sort of phone jack, or what?
It would plug into your home Ethernet connection.

Airport extreme base station doesn't show up on network?

I just set up a wireless airport extreme base station to my PowerBook G4 and hooked my printer to it. All good. I also set up a new iPad wifi, and that also is good. I'm just wondering why the base-station doesn't show up in Finder Network? Any ideas? The Network says Neighborhood, but nothing happens or shows up, when I open it.

this did not solve my questions.
Your question was.......I'm just wondering why the base-station doesn't show up in Finder Network?
We provided answers specifying when the Extreme would and would not appear in the Finder.
As for the "why", here you are asking about design decisions that have been made by Apple. No one on a user to user forum will be able to answer for Apple. If you want to pursue this, you will need to contact Apple directly.
Looks like John Galt has it covered as far as the hard drive question.

Airport extreme base station do i have to connect a modem

just bought a base station connected it to a BT home hub(which constantly dropped the wireless connection on both windows and mac)and it works really well fast and no drops
the only question i have is i thought it was a wireless router why do i have to connect it to a modem the guy in the Apple Store said i just had to connect it into the broadband plug but this didnt work??

The AirPort Extreme base station (AEBS) must connect to an Ethernet connection. Usually this is provided by an ISP's modem or ISP's modem/router combo device.
Typically you would connect the AEBS's WAN port to the Ethernet output of the BT home hub.

Can't see my Airport Extreme base station

I wanted to upgrade my Base station's security to WPA2. So I went to the Airport Admin utility - But the base station does not appear there. My base station is set to be a close hidden network so I suppose that was the reason why it didn't appear.
So I decided to reset the base station. After pressing the reset button for 10sec
I went back to my PB and noticed that my wireless network name was changed to Apple Network ###### (which indicate that the Base station reset) BUT I still can't see my base station in my Airport Admin Utility.
1. Is there another way to reset the base station? did I do it right ?
2. Is there a way to see my hidden base station in the Airport Admin Utility ?
I know that I can log to a specific address (+password) but which one
should I use ?
Thanks
Eric

If you press and release the reset button on the base station, it will restart. If you unplug the power, then plug it back in, it will reboot. Holding the reset button like you did will cause the base station to revert to factory specs, meaning that you lost all of your customizations. So you have to re-configure the base station now.
If your PowerBook was connected to your network, you should see the base station in the Admin utility. Did you check to make sure you were connected to the network before you went into the Airport Admin Utility?
