AirPort Extreme Cisco cable modem and router

Hi all,
I have a Cisco cable modem/router which is being connected to an AirPort Extreme without any problems. I disable DCHP on the Cisco and connected to the WAN port of the AirPort with an ethernet cable.
Now I have a home office with several computers, nas drive, etc and the configuration is somewhat complex to have it messed up. I share a house with another two and while I was away for the weekend one of them decided to wipe off all my AirPort Extreme configuration.
I don't wanna go throught that again so I'm looking for options to having two separate wifi networks, one for home users (Cisco) and my office (AirPort). Since I can't run a cable between them, how can I get internet connection on the AirPort from the Cisco? I don't think joining/extending the wifi from the Cisco is an option since I want two separate wifi networks.
I've somewhat managed to get it working by using a Netgear WNCE2001 to connect wirelessly to the Cisco and to the AirPort with a network cable. The AirPort is then set up to create a new wireless network, configured as DCHP only with a range different than the Cisco. Everything works fine apart form the downloading speed goes in waves, really slow. Upload speeds are fine though. If instead of the Netgear WNCE2001 I connect both routers with a network cable everything is perfectly smooth (same settings on both).
All I can think of is one of those pairs network-through-mains and hope they do the job connecting both.
Is there any other way to have two separate wifi networks sharing the same interrnet connection?
Many thanks for any help you can give.

Thank you for your answer, I'm ordering a set of these http://www.amazon.co.uk/gp/product/B004INVKP4/ref=oh_details_o00_s00_i00?ie=UTF8 &psc=1 and hope they do the job.
I'll get back and tell if they work, might be helpful for others.
Thanks again.

How do I set up Airport Extreme with cable modem and router?

Hi--
I'm having a house built and all of the wiring for TV, phone, and internet will be centralized in a closet. The cable modem can be placed there as well. In one room in the basement I want to use my Airport Extreme for my iMac and USB external hard drives. In another location of the basement, I'd like to set up a Time Capsule for another desktop and USB printer. If the cat5e comes out of the wall at each location, I "think" I need a router at the closet location. I also thought I might need an Airport Express upstairs on first or second floor to boost signal for my laptop. The house isn't that big so maybe that's overkill. So beyond the router question, do I want to set up a roaming network and have the Airport Express connected via ethernet or just wireless if the thought is that I need this? Finally, if I should connect cable modem to router to Airport Extreme, Time Capsule, etc., in what order and ports does the equipment get connected? Many thanks!!

Welcome to the discussions, Forum Girl!
It would be best to position the cable modem and main router in the central location like the closet if possible. The other devices would connect via ethernet to the wall jacks in each room.
If you could setup a "roaming" wireless network as you mention, this will give you better wireless performance and coverage. This is the way commercial establishments like airports, businesses, etc. are configured for wireless.
The order of connection would go something like this: ethernet connection > cable modem >main router>devices. Devices could be computers, routers, a backup device, etc. Since the Extreme has only 3 LAN ports for ethernet connections, you will also need to plan to install an "ethernet switch" near the location of the main router to provide enough ethernet jacks. If you are planning to use DirectTV, etc or your audio/video devices require ethernet connections (most new products do for updates and extra features), be sure to plan for that as well.
Make sure that CAT5e or CAT6 wiring is run so you will be able to take advantage of faster gigabit speeds.
Finally, it would be a good idea to work with an IT specialist to go over your plans to make sure all the bases are covered. This would be money well spent.

Connect extreme to cable modem and wifi to computer?

Currently have dsl connected to extreme then wired to Mac. Considering cable but existing port across the room, prefer not to create another or string a line on the ceiling. Must there be a wired connection to a home computer or can extreme connect to modem and wirelessly interface with Mac ( plus iPad iPhones and apple tv)?

It is also an Ethernet router - wired and wireless.

How to set up 6th Generation AirPort Extreme to cable modem as a wireless router and then connect my 3rd Generation Time Capsule to AirPort Extreme as a wireless extender?

What is the best way to set up my 6th Generation AirPort Extreme (A1521) to my cable modem as a wireless router and then connect my 3rd Generation Time Capsule (A1355) to my AirPort Extreme as a wireless extender? I live in a small 1 story house and I currently have the Airport Extreme connected to my cable modem in the living room and the Time Capsule plugged into the wall in my bedroom. I am able to wirelessly connect to the internet using the AirPort Extreme as my router and I can also do wireless back ups to my Time Capsule. My problem is that my connection seems to be really slow! My 1TB Time Capsule back up is only half way complete and it has been 3 days! My computer has been backing up all day and night for almost 72 hours and its still not even 75% complete. I have backed up to this Time Capsule in the past and it never took this long. I am thinking that when I set up my AirPort Extreme and Time Capsule using AirPort Utility I must have set it up incorrectly or something.
How do I set up my Airport Extreme and Time Capsule for the fastest possible internet speed and back up speed?
Thank you,

AirPort Utility 5.6 works with AirPort Extreme 802.11g base stations.
It works with N version airports.
It will also show details of the AC model but cannot be used for the setup.. mostly.
I purposely got the new 6th Gen Airport Extreme so my internet connection would be a lot faster!
Your network will be much faster when you have AC client directly connected to the AE. Older client will go no faster.. but what is worse.. extend wireless is mixing new and old wireless standards.. guess what one wins.. OLD.. So when you extend wireless.. you have no improvement whatsoever. This whole post is about extending wireless.. so you cannot extend to older equipment and do any better.. maybe slightly better signal although from your comments that isn't happening either.
I would rather not have to use an ethernet at all with the TC and I don't know EOP adapters are!
If you do not use ethernet then you are going to be forced to accept slow speed.
EOP (ethernet over power). Also called homeplug in the US.
http://en.wikipedia.org/wiki/HomePlug
Provides a method of networking over power cabling that already exists in your house.
So what your saying is for the fastest internet speed and back up speed possible I should keep my Airport Extreme plugged into my Modem and keep my TC set up as a wireless extender? Then when I want to do back ups I should plug an ethernet cable from my TC to my MacBook Pro?
To spell this out.
A wireless link to an extended device will go very slowly.. if it is not direct.
So lets say you have a laptop sitting in the lounge.. Your connection goes.. Laptop- - - - - AE- - - - -TC.
That means two wireless links.. wireless has this nasty half duplex and single channel nature.. it can send or receive (Tx or Rx) but not at the same time.
Ethernet by contrast does both at once. It is full duplex.
Wireless can talk to one client at a time.. so if there are multiple items using wireless lets say 4 devices.. then your computer gets a 25% time slice. Since wireless cannot handle multiple simultaneous connections.
Ethernet by contrast can connect multiple computers to multiple destinations at the same time.. all transmitting and receiving at full speed.
When you put all this together.. there are a couple of rules for fast connection.
1. Use ethernet at all times. Where you cannot use ethernet use anything but wireless.. eg EOP (homeplug) at least to try and get rid of wireless.
2. Where you must use wireless use it sparingly and make sure it is never more than one hop.. ie never have an extend wireless (repeater is more usual term). Repeater will cause instant slowdown of 50% and maybe up to 75% just because it is so inefficient.
3. Fastest wireless is 5ghz but it has very short range.. you need to be up close and personal to get it working.
Apple routers however unless you do manual setup I suggest are set to connect to best signal strength not best speed. It will therefore use 2.4ghz at 25% less speed than 5ghz because it is 1db better signal.. this madness means you need to setup manually for the best setup.

Can I use an Airport Extreme as a modem and wireless router?

I realize this shows my ignorance, but I am wondering if I need to lease my isp's (Comcast) modem or if I can use and Airport Extreme instead. Thanks for your help.

AirPort Extreme is a router only.....no modem on board.....so you will need a modem to work with the AirPort Extreme if you want to be able to access the Internet.

Can't find any discussions on this. Suddenly cannot stream video in Safari or Chrome on my iPad 2. The error is "The operation could not be completed." Rebooted cable modem and router, no luck. No problem with my PC. Help!

Suddenly I cannot stream video on my iPad 2. I get the error, "The operation cannot be completed." The browser (Safari or Chrome) continues to try to load the video with no result. I have no problem streaming on my WIndows PC (laptop) using the same WiFi router (Netgear dual band) connected to my Comcast/Xfinity cable modem. I have tried renewing my lease, clearing apps out of memory and rebootng the iPad, still no luck. (How do you do a "hard reset", I forgot?) Frustrating since I don't own a TV and am an Al Jazeera addict! Help!

Airport Extreme joining a network and sharing wired internet connections

Hi everyone,
My new ISP installed their modem/wifi router (Sagemcom) in my home two months ago. Since I share HDDs over the wifi network, I installed my airport extreme near the modem/wifi router and used it to "extend the network", and it worked fine until recently. It stopped working suddently with the yellow light flashing. When I tried to reconfigure it, I always got errors, needing to reset it even to be able to see it again in Airport utility. Honestly, I have absolutely no idea why it stopped working. I tried connecting the Airport Extreme with an ethernet wire to the modem with the same result. So, I decided to move the airport extreme in my living room and use it to share the internet connection with my PS3, slingbox and Apple TV, telling myself that a partly wired connection would improve the signal (since I also had an Airport Express in the living room extending the network before everything stopped working). Now, everything works; the green light is on, HDDs are available on the wifi network, I can only connect to the Sagemcom routeur but, meh, what do you want, BUT, my slingbox, Apple TV and PS3 can't connect to the airport extreme through a wired connection.
Two questions:
1- Is it possible to share a wired internet connection with my Slingbox, PS3 and Apple TV from an Airport Extreme that has joined the network? If yes, what do I need to do to make it work?
2- Any idea why my first setup stopped working?
Any suggestions?
Thanks a lot,
Frank

1- Is it possible to share a wired internet connection with my Slingbox, PS3 and Apple TV from an Airport Extreme that has joined the network? If yes, what do I need to do to make it work?
Unfortunately, the Ethernet ports are not enabled when the AirPort Extreme is configured to "join" a wireless network.
Ironically, the less expensive AirPort Express does have the ability to "join" a wireless network and deliver an Ethernet signal at the port(s).
2- Any idea why my first setup stopped working?
None that you probably have not already thought about. The most commons cause is a sudden power outage, or even quick power "blip" can sometimes result in the Extreme to losing some of its configuration settings. Otherwise, gremlins are hard to catch.

What is the proper config for the Airport Extreme when a Voice over IP device is between the cable modem and the router.

What is the proper config for the Airport Extreme when a Voice over IP device is between the cable modem and the router. Its a VoIPo device. The cable modem is connected to the VoIP WAN port and the LAN port on the device feeds the Airport Extreme. The VOIP is working fine, and my Mac are getting 10. addresses from the Airport Extreme. But I do get confict messages and lose my connection periodicaly. Looking for help.

Its a VoIPo device.
Per chance, is this device the Grandstream HT502?

Cable Modem to Router to Airport Extreme with Dynamic IP?

I have a basic networking question. I have set up a small home network with a few computers. I have a cable modem going to a router with 5 ports. Four of the ports go directly to desktops and the fifth port goes to an Airport Extreme Base station (round one) to provide wireless.
I have set up the router so it is distributing IPs via DHCP. All the desktops are recieving IPs and working fine. The Airport Extreme seems to get an IP and then lose it and the status light on the router goes off.
This made me think that I need to assign static IP addresses to all the computers. I was wondering if anyone could verify whether a wireless router connected to a router needs to recieve a static IP to work or will it work with a dynamic IP too?
Thanks in advance:)

This is the discussion area for Apple's AirPort Extreme base station (AEBS) and wireless networking. Your question has nothing to do with that.
You may want to post your question in the Mac OS X discussion area.

I just moved and Time Warner gave me a new modem and router (Motorola surfboard 6580). Can I now use my airport extreme in the bedroom to extend wireless signal? If so, how?

Yes, if you plan to connect the AirPort Extreme back to the Motorola modem/router using a permanent wired Ethernet cable connection.
No, if you were planning to have the AirPort Extreme extend the Motorola signal wirelesssly.

Should Iplace my ethernet switch between cable modem and airport extreme?

I'm looking for the best placement of an ethernet switch in my home network.
Should I place it "between" my cable modem and my AEBS or connect it to the output from my AEBS?
The current placement is connected to one of the AEBS outputs.
I'm attempting to set up an old AE (802.11 a/g from 2004) with a different network name than my home network, that I'm trying to set up for a college dorm network and each time I plug the AE to the switch to confirm its functionality, my network gets a little confused.
Help appreciated.
Regards,
jim P.

Should I place it "between" my cable modem and my AEBS or connect it to the output from my AEBS?
This all depends on whether you have a simple modem.....or.....a modem/router or gateway combination device.
If you have a simple modem, you cannot place the switch between the modem and the AEBS. The reason for this is that the modem can only deliver one valid IP address and it will be a matter of chance as to which of the devices connected to the switch receives it. The other device connected to the switch will not be able to access the Internet.
If you have a modem/router or gateway type of device, you can place the switch after the modem/router and before the AEBS if you wish, although there is really no advantage to doing so unless this makes things easier for you in terms of hook up.
If none of this makes much sense at all to you, leave the switch in its current location connected to one of the LAN <-> ports on the AEBS since that setup will work correctly no matter what type of "modem" that you might have.

Cannot locate wireless Airport hubs in Airfoil after upgrading modem and router?

Cannot locate wireless Airport hubs in Airfoil after upgrading modem and router? Just replaced modem and router-Airport is working for internet connection, but I cannot locate the two additional sites in my home to feed music to. Each is connected with a Apple wireless hub. Thanks

To work in this configuration, you just need to setup the AX as a bridge.
To set up the AirPort Express Base Station (AX) as a bridge, using the AirPort Admin Utility, connect your computer directly (using an Ethernet cable) to the Ethernet port of the AX, and then, make these settings:
Network tab
- Distribute IP addresses (unchecked)
- Apply the new setting.

My airport is not connecting to the internet. I have a cable modem. and i'm on the internet now connected directly to the modem. what can i do?

my airport is not connecting to the internet. I have a cable modem. and i'm on the internet now connected directly to the modem. what can i do?

I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
If the above steps do not solve the problem, start over with step 1 above, but then perform the next steps between steps 1 & 2. above.
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Continue with step 2 in the first set of steps.
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

HT1126 I've just connected to a Time Warner cable modem and am no longer able to connect to the internet using our Airport Express.

Would love some suggestions as to ho to get thi airport working again!

I too just got time warner. I now have a motorola surfboard sb 6141 attached to my airport extreme. I have had problems with the AE when I was on DSL. I had to unplug it on average every 2 days to reset it as I would loose my WIFI connection. I've updated it to the most recent firmware and I reset it to factory condition when I joined Time warner today.
The modem and router are in the kichen and if I'm on my laptop there the connection is almost alway great. But occasionally it becomes bad. In my office on the iMac the eventhough the signal strength is excellent the speed is either great or exceedingly slow. If I unplug the router and plug it back it, it becomes speedy again in the office. So I guess I need a new router, but this one is only a year old. Any suggestions?
