Connect my Airport Extreme to Comcast modem

I have just ordered Comcast high speed internet service and they installed a Motorola Surfboard SB5120. They plugged it into my computer directly and I thought it was running fine. When I disconnected and tried to install it in my Apple Extreme, it doesn't work. I understand from reading some of the other topics that Comcast protects its bandwidth by not allowing routers to distribute to other computers, but can I change that?
I use 2 hard wire and 2 laptops around the house, can anyone help me configure the modem to distribute the signal?

I have an Arris TM402P cable modem that I rent from Comcast and it has a reset button on back which is accessed by pushing in with a pin or tack. This works to reset the modem without removing battery. Comcast said to disconnect modem from router or computer, hold for 10 seconds, allow to reset for 3 minutes or more, and then connect to router or directly to computer (Mac). This works fine for me and yes you can not switch from direct connection to router or back again without a hard reset such as above.
BTW, are you happy with performance of Apple AirPort Extreme Base Station with Comcast. I'm thinking of getting one since my DLink router seems to be on it's way out - 2+ years old. thanks

How do I connect my Airport Extreme to my modem (Cisco Model DPC3010)?

I am having trouble connecting my Airport Extreme Wireless Base Station to a Cisco Modem (Model DPC3010). I have used the Airport Extreme for years with other modems with no trouble. Alas, this time around I can't get it to work. I think I might not have the cable connected correctly. Help, please. Thanks

Connecting my airport extreme to comcast cable modem-- AGHHH

I've had three Comcast techies to my house since switching over to their triple play offer. Today, I finally got connected to the Internet, through their cable wired into my house, and connecting their modem to my Mac mini (which does not have wireless card). I want to hook up two other laptops in the house, but can't figure out how I do that? The Comcast guy today said with an ethernet cord. So I've plugged the cord into the back of my Extreme, but the other end doesn't fit into the only slot remaining on the back of the cable modem -- which is labeled "phone"... Does anyone know how I do this?
Thanks,
Jill

You need either a router or an ethernet hub/switch between the modem and the computers to give you the needed ethernet ports. Hubs/switches are cheaper but, depending on the Comcast policy on multiple computers on one modem, may not all work at the same time.
A router, on the other hand, allows up to something like 255 devices to be connected. Instead of the Comcast server passing out IP addresses as would happen with a hub, the router issues the addresses to each device. This is useful when the ISP limits how many IP addresses can be assigned to one account (we had this with our ISP--limit of three--and is why we now use a router).
Basically, the arrangement is:
cable from wall >>> cable modem >>> router or hub >>> multiple ethernet lines out to individual computers

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.

Looking for the steps to configure remote access to HD connected to airport Extreme via Surfboard modem

I found an article that seemed a little dated outlining steps on how to access files on my exteral hard drive that is connected to my airport extreme. I have enabled personal file sharing, specified the ports and put in the internal IP address. To test, I am connecting to VPN on my ipad, firing up a browser and trying to navigate to the external IP address and port number specified (xxx.xx.xxx.xx:xxxx) I keep getting a page cannot be displayed error. Any suggestions?

Test from a real WAN connection.. not a loop around via vpn. as it is hard to know where the problem is.. is it the vpn or the port forwarding.
Also it is hard to test from ipad as the only effective protocol to use is AFP on 548 and ipad is not able to do it.
Read Tesserax info on remote access.

Connecting airport extreme, netgear dsl modem, windows 7, and Macbook pro

I'm having a problem connecting my airport extreme to my netgear modem, windows 7 pc and my Macbook Pro. Until a few days ago, I had a Westell wireless dsl modem and everything worked fine. Now, the only way I can connect to the internet is through my desktop pc and the hardwired modem.

If your goal is to extend/boost the range of your Netgear router with either or both of the AirPorts, this will not work wirelessly ... at least, not completely by wireless. That is because, WDS is not standard and each manufacturer has had creative license to implement it as they see fit for their products.
Instead, you have at least two other choices to use the Netgear (as the main Internet router) with the AirPorts:
Connect one AirPort directly to the Netgear by Ethernet, and then, configure both AirPorts for an extended wireless network. In this configuration, you would be running two separate wireless networks; one created by the Netgear, and the second the extended network created by the AirPorts.
Connect both AirPorts directly to the Netgear by Ethernet, and then, configure all of the routers for a roaming network. In this configuration, there would be a "single" wireless network where wireless network clients can literally roam from one router to another and still be on the "same" wireless network.

Can i use my airport extreme as a modem with comcast

can i use my airport extreme as a modem with comcast cable

No, since there is no modem on board an AirPort Extreme, so you will need to use an outboard modem if you want the AirPort Extreme to have Internet access.

How do I connect my Airport Extreme to an AT

How do I connect my Airport Extreme to an AT&T U-verse Modem/Router?

Connect an Ethernet cable between the U-verse router's LAN port to the WAN (circle-of-dots) port on the AirPort Extreme Base Station (AEBS). Since you will have two routers in series, you will want to reconfigure the AEBS as a bridge. (ref: AirPort Utility > Select the AEBS > Manual Setup > Internet > Internet Connection tab > Connection Sharing = Off (Bridge Mode))

Internet connection via Airport Extreme/router thats not working, why?

I have been having problems with the internet connection via Airport Extreme which I find it a bit unusual and its still driving me nuts! This is what happened:
I have lost my internet connection last Sunday evening upon my return from a weekend away from home. The last time I have used the internet connection on my macbook was the previous Friday morning. Prior to the apparent disconnection on Sunday, I have always used my internet connection wirelessly through Airport Extreme (that is connected via ethernet cable to the NETGEAR DG834v2 ADSL modem which had worked beautifully until the problem arose on my return). This wireless internet connection allowed me to surf the internet anywhere in my home.
However, upon the successful re-connection to the internet via the modem router, I have discovered several new problems. I have tried to set up the internet connection wirelessly again but instead the following happened:
1. Router (Netgear) drops ADSL connection and cannot reconnect when connected to airport via Ethernet. (which is the case when using airport wireless).
2. Router connects to ADSL fine when computer is connected to it via Ethernet. (However, router disconnects when magsafe power adapter is taken out for some inexplicable reason!)
3. Router connects to ADSL fine when nothing is connected to the router (ie. No Ethernet connections)
4. Router connects to ADSL fine when connected to airport via Ethernet and computer is connected to airport via Ethernet.
So from the above, I cannot connect to the internet properly whether wirelessly or not so I suspect it could be faulty router or could it be airport extreme? I have asked my ISP for an explanation and all they have said is that it cannot be the mis-configuration but could be to do with the power adaptors or the way plugs are set up and suggested I take out all the power plugs (and power surge protector) out to switch everything off, the macbook, router, printer and airport extreme. However, when I have re-plugged them all back in, the problems I have described above still persists!
Would appreciate any help if anyone here recognises why this is the case and what seems to be the cause of this. If so, what should I do? Though I have written back to my ISP again yesterday for more help so im waiting to hear from them...
Thanks

Cannot connect to Airport Extreme. Did I buy wrong product?

Hello
I am having a problem connecting my Airport Extreme Base Station. I have an iMac flat screen PowerMac G4 running Tiger 10.4.11. I purchased the Airport Extreme Base Station in hopes to connect this and other Mac computers in my house to a wireless network. I have a DSL connection through ATT using a SpeedStream 5360 Ethernet ADSL Modem. I have installed the software that came with the base station. I do have an airport card installed, but it is an older one, not the one that you can purchase through Apple now.
I have read and followed all of the directions in the setup manual. I have seen the base station from my computer, I have given it a name, password, etc... but when I try to finish the installation/setup process, the base station continues the flash an amber light. I have done everything I can think of including reseting the base station back to default settings and starting over. Once I got the base station to show a green light... my computer still couldn't connect. In fact it couldn't even see the base station at that point.
Should I have purchased a different base station for my computer, or could it possibly be my airport card? Another computer in my house (older iMac running 10.3) can read a neighbor's un-passworded base station, but can't connect to mine. Does that give any clues?
Any suggestions would be appreciated.
JP

Just to verify... you have connected the Ethernet output of the SpeedStream ADSL modem to the WAN port on the AirPort Extreme base station (AEBS).
Have you also configured the AEBS to use the correct parameters to connect to your ISP?

Connecting 2 Airport Extremes wirelessly....can it be done?

Connecting 2 Airport Extremes wirelessly....can it be done?
I have 2 Airport Extremes. I'm only using 1 of them right now connected to a cable modem. It works well. I can get a wireless signal in most of the house and even outside a bit. However there are upstairs bedrooms on the other side of the house that I don't get a very strong signal on. No "big" deal really but here is what I thought.......
Can I set up my 2nd Airport Extreme to wirelessly receive the signal from the 1st (main) Airport Extreme and place the 2nd Airport Extreme close to the bedrooms with weak reception? I was thinking that the 2nd AirPort Extreme could just pickup and boost my original signal.
Is this possible? I can't find it mentioned in my Airport Manual.
If so, what is the term for this? That way I can search for information on how to configure all of this. If you have any other ideas on how this might able to work please let me know.
Thanks for your help

OK, you will need to make configuration changes to both of your Extremes.
For the main Extreme (the one connected to your modem now):
Open AirPort Utility, click Manual Setup
Click the Wireless tab under the icons
Look on the wireless setup page and make sure there is a check mark next to "Allow this network to be extended". This may be under the Options tab on the wireless page. If you have a dual band Extreme, you can only extend the main network, not the 'guest" network.
Update to save settings
For the remote Extreme, temporarily locate it near your computer so that you can configure it:
Open AirPort Utility, click Manual Setup
Click the Wireless tab
On the wireless setup page, change the Wireless Mode to "Extend a wireless network"
You will select the name of wireless network created by your main Extreme. Enter the password if needed.
Make sure there is a check mark next to "Allow wireless clients"
Update to save settings
That should do it.

Devices not connecting through Airport extreme wired connection

Hi
I just got an Airport extreme to use as an extention of my existing network, and to plug some devices in so that they can connect to the internet for updates (Sony Blu-ray player, dish network receiver, slingbox)...
my wireless is from a linksys/cisco wireless router (4-port) wrt310n, that is connected to my cable modem. The airport is set and has the green light showing. The blu-ray player and dishnetwork receiver are plugged into two of the ports. The blu-ray player says it can't connect to the internet. The dish network receiver says it is connected, giving ip address/submask, etc.
If I take my macbook pro and turn off wireless and plug into the airport it will not connect to the internet.
What have I not done to allow wired connection to the airport extreme to connect to the net?
thanks
David

Thanks for the clarification of your setup.
Unfortunately, the bottom line here is that this is not going to work.
The ethernet ports on the Extreme will only be active if you configure the AirPort Extreme to "extend a wireless network". But, it can only "extend" a wireless network from another Apple router. It's not compatible for this purpose with your Cisco router or any other manufacturer's router.
If you are unable to connect the AirPort Extreme to your router using an ethernet cable, you might want to take a look at a pair of ethernet powerline adapters to accomplish the same task by using the wiring in your home to transmit the ethernet signal.
I should clarify that if you connect the Cisco and AirPort Extreme using ethernet, you would not use the "extend" setting on the AirPort Extreme. This is only used if the device is connecting to another Apple router.

Do I need to connect the AirPort Extreme with a ethnet cable

Do I need to connect the AirPort Extreme with a ethnet cable

Hi Tracy,
I have an airport express connected by ethernet cable to a Netgear modem which is connected to a phone socket. Those devices stay at one end of the house. I can use my MacBook Pro to connect to the internet (by Wi-Fi, no cables) anywhere else in the house. I hope this helps.
