Have an Airport hooked up to a Cable modem, gives wireless access to 1 laptop but on to anything else

I have an Airport hooked up to a Cable modem. Give wireless access to my MAC Book Pro, connects to my Ipad but will not have internet access, tried a different Airport with the same results. Please help.

Thanks for the info. We will try a shortcut first and hopefully it will work.
On the Mac.....
Open Macintosh HD > Applications > Utilities > AirPort Utility
Click on the AirPort Express, then click Manual Setup
Click the Internet icon at the top of the AirPort Utility window
Click the Internet Connection tab just below the Internet icon
Make sure that the setting for Connection Sharing is set to Share a public IP address
Click Update at the lower right and wait a minute for the AirPort to restart
Now power off both the cable modem and the AirPort Express
Wait 10 minutes. Longer will not hurt at all
Power up the modem first, and let it run for 5 minutes by itself
Then power up the AirPort Express
Check to see if multiple devices can now connect

Why does my airport extreme not recognize my cable modem anymore?

Why does my airport extreme not recognize my cable modem anymore?

Have you tried resetting the modem? Power it down and let it rest a moment, then power it back up again.
Also, some ISPs require physically detaching their cable from the modem for it to be fully reset. Literally unscrew it from the modem. Try that, in conjunction with powering it down.
Don't do anything with your Extreme, other than powering it down too, in the event the modem reset does not help. Reconfiguring it may be necessary but this is not justified quite yet.

Have installed Airport express using windows vista, unit blinks green, selected the speakers from itunes but get no sound at all, even if I put a headphone in the airport express. Pls advise

If the AX is working properly, it should not show up in your list of available networks (since it is "joined" to your router). Have you unplugged and replugged your AX? Unplugged and, after a minute, replugged your router? Do you have MAC address filtering enabled on your router? (if so, disable it to see if the AX works ... it will broadcast its MAC address to the router, and you can add it.) Is your firewall turned on? Turn it off and see if you can access Airtunes. You will have to open a port in your firewall if that is the case.
The AX should have the same network name as your router the wireless tab. When it shows up, what name is it broadcasting?

i have a Linksys Wrt54gs connected to a Cable modem.
it worked for about 8 months.
My kid pressed a button by accident and now it won't work.
the router just keeps resetting.
i unplugged everything.
conencted 1 computer, and everything is fine.
Received DHCP address.
Once i plug in a second computer it starts rebooting.
Both computers are set to DHCP.
NO internet connection is connected at this time for troubleshooting purposes.
Nothing is connected to the ethernet port on the Linksys router (port for internet access), only 1 and 2 are connected.
i reset the router and still nothing.
i can connect 1 computer via wireless and 1 computer via direct connection and all is good. Once 2 devices are connected via direct connections it starts resetting.
i can even connect the modem to the router (for internet access), and connect to the linksys router via wireless from my computer and get internet access.
But once i direct connect 2 connections, the router starts resetting.
i have reset and reboot it with every combination i can think of.

Its good that its working now.
If it happens again, try this :
Press the reset button on the router for 30 seconds. The Power light will start flashing. Turn the Router and the Modem OFF. Turn the modem ON first, wait for 10 seconds, turn the router ON, wait for 10 seconds, you should be ONLINE !!!
Do this when the computer os connected to the router with a cable.
than on the computer open Internet Explorer and in the Address Bar type : 192.168.1.1 and hit enter.
It'll ask for the password. The default password is admin.
Once in the setup page. Click on the Wireless tab.
In there Change the Network Mode to mixed. And change the SSID to your name.
Change the Channel to 11. And Enable the SSID Broadcast.
Save the settings here. After that Click on Wireless Security and configure it accordingly and Save the settrings.
Than click on Advanced Wireless Settings. In there Disable the SES function.
What is the firmware on the router ?

I have an original iPad 32 why can't I connect on my home wi-fi but can connect anywhere else? No problems at home connect with other iPads and MACs.

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

My Airport Extreme Disconnects From the Cable MoDem Every Few Minutes

Hello,
I start a new topic as my previous title was wrong and there was no suitable answer.
I have had an Airport Extreme for 3 years and it sometimes disconnects after a few minutes. Actually, it more looks like that the Airport crashes: the "PC Link" light on the cable modem goes off, the Airport lights go off and I cannot find my Airport Network any more on my computer.
When this happens, I can either unplug it from the power and plug it back in, or simply move the Airport around a little bit, and it will re-start. Sometimes the problem does not re-occur for a few hours or days, sometimes it keeps happening every few minutes and of course drives me crazy...
Is it because ... :
- ... my Airport has a faulty connection and I should replace it?
- ... there are power surges in my electricity installation (eg this seems to happen when I or my neighbors have air conditioners on, I live in one of those old New York buildings with old electricity installations), and I should get an anti-surge device, or a newer Airport would deal with this better?
- ... of something else? I tried replacing the Ethernet cable between the MoDem and the Airport and it failed, there does not seem to be a source of interference around my place.
Thanks for your help!

I have had similar problems. Not as bad as some of you but usually in the morning I discover that I have dropped onto someone elses wireless they are not as fast. Then I have to troop upstairs, unplug the Extreme, replug it and then everything is allright until the next morning. But it is sporadic. It has run fine now for a few days. This problem has persisted now for a year. And yes I have tried resetting it.
Next month I plan on going to the big city and I am going to take my Extreme to one of Genius' at the Apple Store. I am curious if anybody else has tried that solution and how much it might cost.

Airport Express not working with cable modem

I have an airport express that has been working perfectly. I changed my internet provider and it suddently won't work -- no dns, no internet--even though other devices (including apple tv) are connecting with no problem. [the cable modem (motorola) runs through a router to apple tv and the airport express.] I have reviewed everything here and nothing is helping (powered down, disconnected everything, etc) I am at a complete loss. Please HELP.

Configuration is simple if you start from a factory default condition. Connect the main Airport to AC power and to the Internet modem (or modem/router). Open Airport Express on your Mac or other computer and accept all of the recommendations. After confirming that it works, insert your desired administrative and WiFi passwords.

I acquired an airport express to extend my cable modems wireless signal, BUT having difficulty getting set up.

Having trouble getting set up. I'm trying to set up airport express to extend my existing wireless network, so i can get a better signal for my iPad at the other end of the house. I can get a green light on the airport device , but signal is still weak. How do I tell if apple express has been properly set up. Does the apple express need to be connect via ethernet to my cable modem (either for set up or to operate properly)?

I'm trying to set up airport express to extend my existing wireless network
If you are trying to "extend" using wireless only, Apple's "extend a wireless network" feature is a proprietary design that is designed to only work with other Apple routers.
It would be extremely unlikely that the Express could be configured to "extend" a wireless signal from a 3rd party modem/router or gateway.
More likely, the Express has been set up to "join" the wireless network. It does not provide any additional wireless signal in this type of configuration, which is designed for use with AirPlay.
I can get a green light on the airport device , but signal is still weak. How do I tell if apple express has been properly set up.
If you have a Mac laptop handly, you can perform a quick check to see if the Express is actually "extending" the signal.
Locate the laptop near your main router. Hold down the option key on the Mac and click on the fan shaped AirPort icon at the top of the screen. Look for the BSSID and jot down the least few numbers for identification. The BSSID is actually the AirPort ID of the device to which your Mac is connected at that time.
Now move the laptop close to the AirPort Express and perform the same check, If you see the same BSSID, this confirms that the laptop is still connecting to your main router's wireless signal...and the AirPort Express is not "extending" the wireless signal.
If the Express is "extending", you will of course see a different BSSID when you perform the check.
Post back on your results, so we will know how best to proceed if you want to configure the Express to provide more wireless coverage. It will help if you can provide the make and model number of your "modem", which is likely a combination modem/router or gateway type of device.

Hooking up a SBC Cable Modem

Have tried several times to configure my MAC PB"17" to a SBC / Motorola Cable Modem. SBC and Moto can not assist...
Can anyone assist with setting that will work with my Airport Extreme.
Much Thanks,

I dont think that your cable box can stream contents thru its USB ports, that wont work. Also check your video card s-video plug, most likely it's video out only (for TV monitor). You need some kind of input device for your pc to be able to connect it to your cable box, either a TV tuner card, a capture card (usb or pci card) etc.

Using Airport Extreme Base Station with Cable Modem

Hi everyone,
I have just bought an Airport Extreme Base Station. I connected it to my cable modem (Surfboard 3100) through the WAN port and my iMac G4 is connected to it through the Ethernet port. Installed the Airport Utility, and configured the base station with the normal settings of DHCP for Internet and DHCP for internal network.
After restarting the base station, my Internet connection from the iMac through the base station is very slow and most of the time will time-out. My Internet connection through my PowerBook G4 using wireless through the base station is ok though.
My question is, is there some setting which I should set for the Ethernet portion of the base station to make my wired connections to the Internet work?
Thanks in advance for any help!
regards,
Weiming
iMac G4 Mac OS X (10.4.10)

Hi,
My iMac G4 does not have an Airport card. I did not physically restarted the base station, its part of the sequence when we update the configuration, that the base station will restart on its own.
regards,
Weiming

Airport Extreme doesn't see cable modem

A new Airport Extreme refuses to see an Optimum Online cable modem. As for troubleshooting, I've seen the new AE working at an Apple authorized store, bought a brand new ethernet cable, but still only get a blinking yellow light. I can plug my G5 directly into the modem with no problems. Any thoughts?

I had a similar problem once. Turned out Verizon (the ISP) had their DHCP server bind to the MAC address of the first machine connected to it and wouldn't issue a new IP address to another machine (MAC) address, unless you either:
1) let it time out like 45 mins!
2) you spoofed the MAC address of the old device on the new device. (Can't do this on the AEBS, unfortunately.)
3) you connected the old machine and (rather than just disconnect it after it got an address from the DHCP server), you actively released the DHCP address.
Until I found out this vital DHCP server behavior info (after waiting an hour on hold with tech support and then working through level 1 support's noob scripts), I too was playing around with resetting the modem, etc., etc. The problem however was the ISP's DHCP server 'security'.

Suggestions for Cable Modem and Wireless Router

Hey everyone!
I have the new iMac and would like to have a faster wireless router. Currently using an old D-Link Wireless G router and would like something like the Time Capsule (as it has Airport Extreme in it) or Netgear Rangemax Dual Band Wirless-N Gigabit Router. My problem is, my Internet is through my cable company, so it comes into the house as a cable connection. It appears that these two combos would still require the use of a cable modem.
Any suggestions to keep the equipment down to one piece? If not, any suggestions for a cable modem so I can return this old one to the cable company?
What would be the best/quickest wireless router?
Thanks for your help!

Go to your ISP's web site and do a search from your ISP for compatible cable modems. Then buy the capable modem your ISP says that is comp[atible. On the new cable modem find the Serial number & MAC address, make then call your ISP tech help desk and tell them the new modem you got and he/she will ask you that information. When the ISP tech says they can see/ping that new cable modem then it will work. Then connect a new cheaper Airport Extreme and any external USB2 hard drive to connect to that new Airport Extreme. I say this because Apple put out and Update a little while ago that will allow an external connected to an Extreme as a Time Machine disk.
PS: Remember the old trick of checking you Ethernet cables. I can't count how times I have seen professionals install all new high speed switches, routers, etc. and wonder why no speed is seen. Then after numerous trouble shooting they discover they used the old 10 Base T cables and just changing the cable solved their problem.
Just make sure you do this one at a time starting with getting the ISP compatible cable modems list to know what cable modem you can buy (to save that monthly ISP rental fee). Then you can get the going as long as so speak with your ISP tech to give them that new cable modem Serial number and MAC address so they can register it with their servers.
This will be to easy as long as you do things in step.

Cable modem/Voip wireless modem/AE

I currently have a cable modem connected to a voip wireless router and would like to connect them both to an AE and move the modem and router away from the computer (we would like to move our tv away from our computer). Is there any way to do this? We are running windows xp.

The "VOIP wireless router" must remain cabled directly to the cable modem.
What you can do is set up your computer to connect wirelessly with the "VOIP wireless router" - and since this is a PC, I suggest you buy a PCI wireless network card (if it is a desktop) or a PC Card wireless network card (if it is a laptop). This would allow you the freedom to locate the PC anywhere within wireless range of the "VOIP wireless router".
Unless you want to make use of an Airport Express for wireless iTunes streaming or printing, an Airport Express is of no use for what you are trying to accomplish.

Have an Airport hooked up to a Cable modem, gives wireless access to 1 laptop but on to anything else
