Sharing Internet via Airport Extreme using a USB wireless modem

I have had to go to NextG access using a USB modem (only option). We previously succesfully had the second iMac sharing the internet connection on an ethernet-connected wireless service. Now, I cannot get the other iMac to share the connection, because there is no option to choose the USB modem.
Another problem is the USB modem is top-dog - it won't connect unless I turned off anything else using anything remotely looking like wireless (even when I have my bluetooth phone connected to another USB hub). I can connect to the NextG network after disconnecting everything else and THEN reconnect, but I just can't get the Internet sharing going. I have also had the iMac freezing, demanding a power-off-power-on (unheard of in my experience!).
Is there any remedy for the Internet sharing at all? Configuring a different channel or something on Airport? Using one of the other config options?
I think there are something like USB-to-Ethernet adaptors (pretty costly here in Australia) and don't want to shell out for one if it doesn't work. Same with a third-party router. I also wondered if I should just forget about using Airport completely and run a few metres of crossover cable?
Any help would be greatly appreciated, thanks.

Hi Steven, I know this question has been answered and is a couple of months old but I think you may be able to help with my set up? I have a Thomson speedtouch 510 v6 modem router provided by Karoo (UK). My other Belkin N modem router has just bust [again] so the Speedtouch is my old faithful backup device. Now, i've never been able to get on ichat with the Belkin as its a mimo n speed and this is apparently not compatible; So i'm now on ethernet with the st510 and have just set up ports for ichat thanks to a thread called http://discussions.apple.com/thread.jspa?messageID=2719419&#2719419.
What I want to know from you (because I really need a wireless router to get me off this ethernet support system and back on airport) is how you're getting on with the st510 / airport extreme combo now and can you use ichat on it? If so does your connection doctor say full cone in network settings or something else? As I say, I really want to use ichat and have never been able to in 3 years of owning my Macbook Pro. Hope to hear back from you Steven. Regards Steph

No Internet via Airport Extreme and Speedtouch Ethernet DSL modem

I've recently purchased a McBook pro and wanted to create a wireless network. I have a new Airport Extreme Base Station and have successfully set that up, but with no internet connection!
I can get a perfect connection by hardwiring either of my machines to the DSL Modem directly (via Ethernet cable), but when i connect the Airport Extreme to the DSL Modem via ethernet there is no internet.
After a bit of research i'm wondering if there is a "bridge" issue... though i have no idea what that means or how to resolve it. Can anyone help?
Details:
Airport Extreme 802.11n
Speedtouch DSL Modem (Thomson ST510 v6)
G5 Power PC Tower (10.4.11) will connect to the Airport Extreme via ethernet, currently connects to the DSL modem via ethernet.
MacBook Pro (10.6.4) will connect wirelessly. can currently connect to the internet through the DSL modem via ethernet.

2 Computers Cannot Access Internet Via Airport Extreme at the same time!

I recently purchased two new computers -- a Macbook Pro (for myself) and a Macbook (for my wife). My Macbook Pro arrived first, and connected to the wireless network via Airport Extreme with no problem. Once my wife's computer arrived, and we would connect to the network with her computer, every time she accesses the network it basically "boots" my computer from the network. It still says I'm "connected" to it, but no programs/browsers/etc. that use the internet will actually work and it behaves as though there is no network connected at all. In the mean time, her Macbook continues to operate as normal and never seems to get "booted" by my Macbook Pro. Is the network thinking our two computers are the same computer? Or, what is the problem? PLEASE HELP!

I have had the same problem with my iMac and MacBook, both on leopard and with a new AEBS. With the additional symptom that internet connection will drop on either machine individually, with the other powered off. I also tried a Time Capsule, with exactly the same results. But I have observed what is described here. Internet connection is fine on one machine, then drops and I find the other machine working for awhile, until it drops. Just ping-ponging back and forth.
Since I am seeing the same problem in two new Macs with an AEBS and TC, it's hard to say that there a problem specifically with any one of them. I suspect that my problem is interference, or electrical noise when using 802.11n. The only thing that worked for me is "802.11b/g compatible" mode.
In another post, it was suggested that the AEBS was interacting with Digital cable TV/internet, potentially causing an electrical noise issue. What kind of service to you have?

Can't get windows 7 netbook onto wireless internet via airport extreme.

I've spent 3 days trying to get my new Acer netbook with windows 7 home premium in it on the internet wirelessly through my Airport Extreme. It shows the internet is there but will not connect. It keeps asking me for a security key. I have tried my system password and the airport password, neither of them work. I have a feeling I'm just missing something in one of the settings but I am a die hard Apple/Mac user and this little windows machine is really killing me! The airport is working flawlessly for my Imac desktop and my Ibook so I know it isn't the airport. Anyone have any suggestions (other than getting rid of the Netbook?)

I'm kind of having the same problem. I can finally connect and get on the internet wirelessly but I can not setup my Airport Extreme. I just moved recently and I didn't have any issues at my old place and now I can use the internet and I get this blinking amber light and it's kind of annoying. Every time I click Manually Setup or Continue in the Airport Utilities my computer will try to detect any Apple devices, even though it right there on the left side it can not connect to it. At the same time I click either button my wireless disconnects for a second and reconnect.
I can't setup my Airport Extreme using this garbage OS they call Windows.

Connect 3 LANs over internet via airport Extreme

I have 3 offices for my small business and would like to connect all 3 LANs for a variety of operational reasons without getting a virtual LAN from the ISP (as this is cost prohibative and we have 3 different ISPs due to geographic locations).
I have heard this is possible via Airport Extreme, but I am unable to find any documentation on the matter.
Thoughts?
Thanks

Also should note that at the primary location I have a Mac Mini q-Core Lion Server.

Airport Extreme 'n' and USB External modem

Hello all,
I have an Airport Extreme 802.11n simultaneous dual-band base station with a USB disk plugged into the back through a hub. It's connected to my network that comes from my 802.11b/g Airport Extreme Snow "saucer" model that I have to have because I can't get DSL/cable where I live, so I use the built-in modem to access the internet.
Can I add the USB External modem to the newer Extreme and still access the internet through it, or is that basically a lost cause? I'd like to move to the new one because 'n' would be faster to do my time machine backups.

The USB cellular modem you are referring to would be a device like this:
http://www.cradlepoint.com/products/cba250-cellular-broadband-adapter
Your USB adapter would plug into the Cradlepoint and the Cradlepoint would provide an ethernet signal to the WAN port on the AirPort Extreme. That's the only way this type of setup will work.

How to use iBook for sharing internet via airport card... can it be done?

The title says most of it all. I want to share the internet coming from the wall through the airport card in my iBook. I've made it work, however I'm concerned about doing it securely. Can it be done securely? If so, how? I've read in the help files about using the firewalls and such, but I'm having trouble making heads or tails out of it all. How about a primer on basic wifi security in the iBook's Airport card environment? I'm not as savvy as I used to be! Thanks in advance for your help.

Requirements for wireless Internet access
To use AirPort to access the Internet wirelessly using Mac OS X, you need:
An Apple AirPort Card, AirPort Extreme Card, or a compatible third-party wireless card
An AirPort Base Station, Time Capsule, AirPort Express, or an AirPort-enabled computer acting as a software base station (if you are hosting an AirPort wireless network)
Internet access
Some Internet service providers (ISPs) are not currently compatible with AirPort.
If you’re setting up an AirPort Base Station, Time Capsule, or AirPort Express to connect to the Internet, you need an account with an ISP. When you set up your account with your ISP, you were most likely given account information (such as user or account name, password, phone number, and possibly other information). Have this information ready when you set up your device.
If you are connecting your base station to an Ethernet network that already has an Internet connection, you may need an account name and password to access the network. Check with the network administrator if you’re not sure.

Problems sharing internet over Airport extreme

I have a PowerBook G4 (OS 10.4.11) with a USB wireless broadband modem connected to the internet. I bought each of my daughters a MacBook (OS 10.5), and the idea was for me to have my laptop connected to the internet, then use internet sharing via my airport extreme card so that the girls could access the internet from my connection across airport.
I have no problem using my wireless broadband to connect to the internet. I have no problem firing up my airport extreme and creating the network, and I have no problem creating the internet share. I all seems to be working at my end. On the girls MacBooks, we have no problem firing up airport and connecting to the airport network I created. However, when we fire up safari, all we get it "you are not connected to the internet".
I'm lost. Any ideas?

cdelahoy, Welcome to the discussion area!
On your PowerBook G4 do you have the firewall enabled? If so, try go to System Preferences-> Sharing preference pane and enabling Personal Web Sharing. That should open the ports needed to give Internet access to the MacBooks.
If that doesn't work, try disabling the firewall on the PowerBook G4.

I cannot get past Gateway PING when connecting Samsung BD player to Internet via Airport Extreme?

I have now been trying for 2 days to get my Samsung 3d BD Player to connect to my wireless iinternet (via VIVID WIRELSS) in Australia. I am using an Airport Extreme Base Station WIRED to the BD Player and wirelessly connecting to the WiFi. The Network Test shows Ok for MAC and IP, Gatewy, DNS etc... but wont get to the Internet test because it stalls at Gateway Ping. I have tried all of the various setup changes - Auto, manual, changing the adresses but noting works. Sometimes it takes longer to fail the Gateway Ping (when I put in the WAN settings as opposed to the LAN settings but none work.I know I have the correct info in my WiFi setup with the password and security etc... Is this just an incompatibility between Samsung and Apple? It worked fine with my Pioneer player and also my Panasonic Player? Any help gratefully accepted!!!

I assume that these results are coming from the Samsung BD player's network administration interface ... correct?
When configured to join another wireless network, the Extreme is also reconfigured as a bridge. That means all IP address information must come from the upstream router that is providing DHCP server services ... so the Samsung is actually testing the upstream router's connectivity to the Internet, not the Extreme's.
I am venturing to guess that if you plug the BD player directly into the upstream router, it would not have any issues connecting. So, this would confirm my earlier statement that Ethernet ports on the Extreme are not enabled.
I would further guess that if you connected the Extreme directly to the upstream router by Ethernet and configure it for both Wireless Mode = Create an wireless network and Connection Sharing = Off (Bridge Mode), that the BD player would get the proper IP addresses it needs for Internet connectivity.

Facetime "Fails" to connect via Airport Extreme using Comcast?

Greetings,
First time poster... tried researchings specifics on my situation and couldn't find anything so posting here to see if a solution has been found.
I used to have Verizon DSL for ISP with Airport Extreme as my wireless router. Everything worked including Facetime (only issue was the need for speed). Switched to Comcast as ISP which uses cable and had the Tech reconnect it to the Airport Extreme to behave as the wireless router. Internet is on and good... got a green light on the Airport Extreme. However, when attempting to connect via any device using Facetime (it will ring but as soon as it is answered I get "Fail" message and it ends) be it my laptop, desktop or either of our iphones I have IOS7 and IOS6 respectively same error. Did not make any modifications to Airport settings or any of my devices.
When checking the common response to this issue was a potential "Blocked Port" situation... but by digging a little deeper it appears that Comcast does not block ports that are relevant to Facetime (please confirm). I didn't see anything else that would suggest a solution at this point.
Help would be greatly appreciated as we enjoy using facetime to have our 6 month old daughter connect to our grandparents.
Thanks,
Andrew

The USB port on an AirPort Base Station other than the 802.11n model is only for use with an USB printer; hard and flash drives will not be recognized. The compatible base stations include version 5.0 of the AirPort software on a CD.

Can't connect to internet via AirPort Extreme with Laptop running Vista

I've seen a lot of posts on this topic, and maybe I'm just out of luck, but anyway...
My PC running XP can connect to the internet through the AirPort Extreme, but laptop will not. I load the AirPort Utility on the laptop. Should I be able to see the base when I run the Utility? It does not see it. I can see the wireless network with excellent strength, but all I can do.
If I can't get this to work, I'm going to just return it and to back to the wireless router. I was enticed by the ability to connect the printer and external hard drive to the base. I would like to get rid of the PC and just use my laptop for everything.

Looking over your original post again, I think I might have misunderstood you the first time. If I understand you correctly, your Vista laptop can see the wireless network and connect to it (so you have access to the Internet), but you cannot see the Airport Extreme Base Station when using Airport Utility.
If your Internet connectivity is not an issue and it's just that you can't see the base station in Airport Utility to configure it, try using an ethernet cable to connect your Vista laptop to one of the LAN ports and see if the base station shows up in Airport Utility then.

Can't Access Server from Internet (via Airport Extreme)

Not sure if this is an Airport Extreme or a SL Server question, guessing the latter?
From my local network I can access the OSX Server home page by entering the URL myserver.dyndns.org (domain registered on the DynDNS site) in Safari. The server is setup with a fixed IP.
I have a dynamic IP from my ISP, and am updating the domain mapping to the IP address using an Airport Extreme and completing the dynamic global hostname info. When I ping the domain I get the correct IP address. The Web Server is running, but I am using default configuration info (perhaps my problem? not sure, working fine from the local network). I have a bunch of ports open on the Airport Extreme, and pointing at the server IP address (including 80). But when I try the URL myserver.dyndns.org from the Internet (outside my local network) I can't connect.
Anyone know what I am doing wrong? Thinking it must be simple!

ISPs usually block port 80 for home users but leave 8080 open. Actually you could use any port number you want as long as you redirect it to port 80 on your server machine using the Airport. Once you set it up have someone outside your network try to access it by using your IP address and port number you assign, eg. http://123.456.789.101:8080
That should bring them right in.
I use this method to host sites on my Mini Server at home and use DynDNS with port forwarding on my domain names.

Connect to internet via airport extreme via ethernet cable and no airport c

I just bought a MacBook with Airport Extreme, got it set up today and it works great, got online, etc. However, I have an iMac with no airport card. I can't figure out how to get both computers hooked up on the internet at the same time. The MacBook works only when the ethernet cable in in the LAN slot on the Extreme but won't work through the WAN slot. I have tried hooking up both ethernet cables into the Extreme, just the iMac, and nothing works. I don't need to connect wirelessly through the iMac so I don't want to buy an Airport card if I don't need one. I just don't want to plug and unplug the ethernet cable everytime I want to use the MacBook or the iMac. My modem from Verizon only has one ethernet slot. Any ideas?

You mean Airport Extreme Base station?
Here's what you need to do:
1. Disconnect your Verizon Modem & Airport Extreme
2. Connect the ethernet cable from the Verizon modem to the WAN of the AE
3. Connect another ethernet cable from the LAN port of the AE to your iMac
4. Turn on Verizon Modem
5. Once all lights on the modem have turned on, turn on the Airport Extreme
6. On your iMac click on Applications --> Utilities --> Airport Admin Utility
7. Setup a Wireless network using this or the Airport Setup Assistant, located in the same Utility folder.
8. After you have created the wireless network, connect to it on your macbook

Macbook connectivity to internet via airport extreme is flakey

Hi,
Just bought a brand new airport extreme and I already own a June 2009 Mac book pro w/ snow leopard.
I always run software updater, so the Airport 2009-002 patch/fix is on this system.
I have a strange problem with my connectivity to the internet from my mac via the airport extreme.
Very regularly (and seemingly randomly) the laptops connectivity to the internet will drop out... i.e. websites won't respond, big websites (like google) don't respond to pings or anything. While these internet "drop outs" are happening, i can jump onto my PC (which is connected to the airport extreme via ethernet) and the internet is working fine.
Also, Wifi never drops out through this whole situation. This means that while I can't access the internet, my reception is still FULL and I can SAMBA connect to my PC and with other computers on the network.
It's very strange that purely internet via the Airport Extreme is having these issues.
The Airport is in Bridge mode (which means the ADSL modem/router is the DHCP server). The ADSL modem/router does not have wifi active or anything connected to it (other than the airport).
I've never had any issues with my internet - this is the first. My only real option if this can't get resolved is to return the airport, as this is inhibiting me from working from my laptop.
Anyone else experience similar issues?
Can someone recommend any course of action to work around this issue?
Is there anymore information this forum needs to debug this problem? How can I obtain this info?
I hope someone can help.
Regards,
Vijay

I seem to be in a very similar predicament, however I'm served even worse:
I'm loosing Internet connection over both LAN and WIFI. And the Airport Extreme does not detect the loss of connection even though the logging indicates the internal ntp client (trying to connect to time.euro.apple.com) fails (already on dns resolution).
Currently, I'm dvlp-ing a shell script that checks 4 websites, and if all 4 are unaccessible, I launch an applescript that restarts my airport extreme basestation.
This however does not always seems to solve the problem. Seemingly I would have to reset the modem.
The problem can - according to me - not be provider related, since it does not occur when the TimeMachine is replaced by a SL-installed mac mini (that however cannnot function as router (yet)).
Any hints ? anyone ?
I previously had installed an Airport Extreme 10/100 version, which showed the same behaviour. Since the system was out of warranty, I decided to upgrade to a faster system, including TimeMachine, but unfortunately, the problem is still there.
I'm guessing now it could be related to the router being configured in dhcp (getting its ip address over dhcp), but the server provides a static ip address (never changes),... and maybe here there's something fishy.
