Xfintity router/modem with Airport extreme moderate/strict nat?

I switched to comcast xfinity and they gave me a modem with a router built in and we are trying to use the Airport Extreme to get better signal using Bridge Mode in Airport Utility. It all worked fine but then on my PS3 and Xbox 360 it says that I have a moderate/strict nat type any help on how to get a open nat?

Suggest that you double check to make sure that the AirPort Extreme is setup in Bridge Mode.
Open AirPort Utility - click Manual Setup
Click the Internet icon
Settings should look like this:
Connect Using = Ethernet
Connection Sharing = Off (Bridge Mode)
Update to save any changes
When the AirPort Extreme is in Bridge Mode, DHCP and NAT are turned off.
These services are being provided by the Comcast gateway, so any NAT issues rest with the Comcast gateway. You may need to call Comcast support to ask them about changing the NAT settings on the device.

Which non apple modem/router work with airport extreme

Hi
My old modem needs replacing. It currently feeds into my airport extreme and an airport express extends the network to my office in the garage. Ideally I want an 'n' speed modem/router and use the airport extreme to extend the network in the garage, doing away with the airport express's slower speeds.
Are there any non apple modem/routers that will work with the airport extreme to extend the network.
Many thanks

+Are there any non apple modem/routers that will work with the airport extreme to extend the network.+
Not if you are planning to "extend" using wireless only.
If you are planning to extend the network by connecting to your new modem/router using an ethernet connection, you have some configuration options to choose from in that case. Post back if you need more details about this.

Comcast Arris Modem/Router interfering with AirPort Extreme?

Constantly getting knocked off the internet. Using an Arris Modem/Router TG862G
and an Apple Airport Router.
3 feet separate each router.
Am I getting knocked off the internet; because my AirPort Extreme is "confusing" my Arris Modem? Could interference cause internet disconnections?
Or is it likely something else?
Thanks

I had this same exact issue occur when I connected a printer to my Time Capsule, literally unplug everything from the router i.e. printer, computer, etc. etc. and wait a few minutes. Then re-plug all the peripherals (try different ports, except the LAN ) and see if that solves your wifi issue. If not, then unplug the router and just "give it a rest" then re-plug everything. If that doesn't work then defineitely try a hard reset or see if one of your connected devices is interfering with the network. In my case it was the printer that screwed up my connection and not the modem. I would also try switching LAN ports on the modem and see if that helps.
Hope this helps!

Do I need to use a modem with Airport extreme?

I am trying to set up security cameras for my 90 yr old mom, and need to know if I need a modem with the Airport Extreme device?

You'll need a modem to connect to the Internet. It doesn't have one built into it.

Cisco router RVS4000 with Airport extrem and Time capsule.

Problem droping connection to internet when is Time capsule in extended wifi mode. When I turn off wifi on time capsule Airport extreme work fine.
Airport extreme and Time capsule is conected via ETH.
Any idea ?

If you use ethernet to connect the AE and TC .. you must NOT extend wifi.. you use Create a wireless network. And setup with same name and security. You are using roaming network.. not extended wireless.. if you want to use extended wireless no ethernet

Using a second router with airport extreme

I have hooked up a second router to my airport extreme for the purpose of providing more ethernet ports. When I do this I disable the wifi on the second router and place it in a bridge mode to let the airport do DHCP.
However none of the PC's in the house can access the internet when plugged into this second router. My mac can access the internet through this second router, however. If I enable the second router's distributions of DHCP, the PC's can access the internet. I an certain this is wrong, however because if my mac is hooked up to this second router my "back to my mac tab" in System Preferences > Mobile me gives me the Double NAT error.
I have tried two different routers attached to the Airport Extreme with the same results. What do you think?

I don't think it needs to be spinning all the time, others disagree with me, whatever is the correct answer it doesn't matter as there is no way to stop it. Hopefully we will at least have the option at some time in the future to let it spin down.

Acouple of days ago I kept losing connectivity with the internet.By resetting either my modem or Airport Extreme I could regain it for 10-30 min. when I would have to repeat the resetting.Since with Apple

Edge has very clear restrictions, one being that you must have 6 months of clean payment history which you don't. Either wait until April 14, or good luck at Sprint.
I am unsure how it can be determined the payment mix up was the fault of CS, but regardless, the mix up was done. There can be any number of reasons why a payment could be missed without any fault on your part, however you are still the responsible party for the account and must live with the repercussions.

How to configure home network with Airport Extreme + D-Link DIR-665

*hello everyone,*
*I had these two working fine together until the D-Link took a dump the other day. No explanation. Just stopped working until I reconfigured everything.*
*Which then led to my Airport Extreme being unable to connect to the network at all, much less the internet...*
*My home network is set up like this:*
*Optimum Cable*
*Motorola Surfboard modem --> D-Link DIR-655 (via ethernet)*
*- Provides wifi and ethernet connections on one side of my house*
*DIR-655 --> Airport Extreme (via ethernet run to other side of house)*
*- Provides wifi and ethernet connections on the other side of my house*
*My MBP won't connect to anything other than my AE running N, so I have that set up primarily for my MBP over wifi, while feeding an ethernet connection to a Netgear router running B/G, for my iPhone and other devices.*
**So here are the relative details:**
*I decided to start fresh and do a factory default configuration with my Airport Extreme. My working system from earlier was essentially it's own wifi network, but the airport utility 'insists' that I need to run my AE in bridge mode. I've tried that, but I can't get online. I can see my shared connections, so something's getting through, but I cannot connect to them, in addition to being unable to get online.*
*I'm not really sure how to best illustrate this problem, so I've ran through the process again and jotted down a few notes. Excuse the rambling nature of my narrative, this is a 'blow by blow' account of the Airport Utility setup process:*
Airport version 7.4.2
IP address 192.168.0.192
router address: 192.168.0.2
Configuring over Airport connection.
- I want AE to join my current network
-.. connect AE to my network using ethernet to extend or create second network
- select device AE will connect to using ethernet - DIR-655 network (displayed w/ airport icon?)
- create an additional network (through ethernet)
AE updates..
- problem 1 of 1 : unsecured wireless network
wpa wpa2
Bridge mode or share a single IP address using DHCP
selected bridge mode
results: AE has green light, airport utility is satisfied but no connection to network is possible. Shared connections are visible, but unable to access
next try:
manual setup
Wireless mode: create wireless network
radio mode: 802.11n only (5 GHz)
channel: auto
wireless security: WPA2 personal
(bridge mode still active)
(this is the exact setup that worked for years before..)
updated…
AE light is green, but no connection to internet or shared connections (though visible)
back to airport utility
manual setup:
internet menu:
connection sharing: share a public IP address
update
--> 2 problems
DHCP Beginning address: 192.168.0.2
DHCP Ending Address: 192.168.0.2
chose 'assist me'
(now one shared connection to Mac Mini becomes active? Had selected it earlier. Able to browse folders, but not share screen)
AE refreshed now with amber light, with reported problems
Problem 1 of 2: Internet Connection
Your Apple Wireless device does not have a valid IP address. Make sure your Apple wireless device is connected to your broadband modem or local network… etc
- changed IP address to match router IP address (?) Utility goes on to next problem
Problem 2 of 2: Conflicting DHCP Range
This Apple wireless device rejected a DHCP address in the same subnet as its internal DHCP server. You should probably switch your Apple wireless device to be in bridge mode. If you still want to be using DHCP and NAT to share a single IP address, you should change your DHCP range.
- maintain selection: share a single IP address using DHCP and NAT (utility forces you to: ignore; skip; or select bridge mode - which doesn't work..)
- chose 'skip' for problem 2
- updated AE..
New problem:
Problem 1 of 1: Double NAT
This Apple wireless device has a private IP address on its Ethernet WAN port. It is connected to a device or network that is using Network Address Translation (NAT) to provide private IP addresses. you should change you Apple wireless device from using DHCP and NAT to bridge mode.
- selected Bridge Mode
updated AE…
"Setup Complete!"
Unable to connect.
** At this point, I am still able to see my shared connections, and while iTunes is open, I can play my shared library that is on my Mac Pro, which connected to the DIR-665 via ethernet, through yet another D-Link router (DIR-615)! I am still connected to the Airport Extreme via wireless, so the system is working, to an extent.*
*So I'm not sure what to do. How can I remedy my IP address issue? Bridge mode doesn't work (as far as I've experienced), so I'm struggling with my DHCP settings..*
*Thanks to anyone who has any suggestions!*

Hi Preston,
I would recommend not starting the numbering scheme for the IP addresses using a '0'. Yes the range is 0-255, but some numbers are reserved, and not generally good practice.
Also, assuming you have reset all factory defaults, start anew and have the modem --> router using NAT for dynamic IP addresses --> (other side of the house) Airport Extreme --> not a NAT configuration, but you need a simple switch. Do not use the NAT capabilities on this one. Maybe, just maybe the computer will work now. This will eliminate your double NAT and also help (hopefully) with the D-Link.
Sorry I cannot help more, I do not own any of the products you talk about, however I have networking experience. Hope it helps.

How-To Set Up with Uverse Gateway with Airport Extreme

I just spent hours figuring this out so I thought it would be helpful to someone. Maybe, maybe not. My goal was to get Back to My Mac turned on...but this should also be how you set up your wireless network if you have both an Airport Extreme and a Uverse Gateway.
As I was trying to setup BTMM, I got a "double NAT" error. To use BTMM, you have to use either Time Capsule or Airport Extreme, so that NAT has to be enabled. That meant I had to figure out how to turn off U-verse's. I looked through the settings but saw nothing about it. Several hours of research--and a useless support call to AT&T--I finally figured it out. Here's the configuration you need, in brief.
On the Airport Extreme, under Internet > Internet Connections, Connection Sharing must be set to "Share a public IP address". Then under the NAT button, Enable NAT Port Mapping Protocol must be checked.
Now, unless you doe rest of this configuration, you will get a double DHCP error. So, in the Uverse Gateway settings, you must do this:
1. Under Wireless, click the option to DISABLE wireless. Click Save.
2. Under Firewall, click the option with DMZ in the name. On this page, choose your Airport Extreme (whatever you named it). Then scroll down and choose the option that says "Allow All Applications (DMZPlus Mode)". Save that configuration. DO A HARD RESET ON THE AIRPORT EXTREME. Then that should enable a single NAT protocol and BTMM will be on its way. And your wireless network will be set up properly.

Will the above method work on a set up with a Verizon Modem to a DLink wireless router to a Time Capsule?
I know of no reason why it would not. Whenever there is another router ahead of the Time Capsule, the Time Capsule must be configured in Briddge Mode. My network has 4 routers. The "main" router is setup to handle DHCP and NAT and the other 3 routers are setup in Bridge Mode. No problems.
Weird thing is Air Video set up tells me I have a double NAT
Double NAT occurs when you have two routers on a network both set up to handle DHCP and NAT services. Your Verizon "modem" may be a gateway....a combination modem/router on the same chassis. If that's the case, then every other router on the network must be confgured as a "Bridge".
If you have the "main" router on the network setup to handle DHCP and NAT, in theory, you can have multiple other routers on the network as long as they are all setup in Bridge Mode. In Bridge Mode, DHCP and NAT are turned off, so the other routers simply pass through the network information from the main router. It's by far the easiest way to configure multiple routers without having to go into special DMZ, port mapping, etc type of configurations.

Is anyone successfully using Netgear WN3000RP with Airport Extreme?

Got a brand new WN3000RP wifi range extender. I went through the installation several times myself and several times with tech support to no avail. Tech support told me to return it for a new one.
Everything is connected and the install process goes smoothly but I ultimately cannot ever use the extended network to connect to the Internet. I can see the range extender's mac address on the router but the two devices don't seem to talk to each other.
I'm just wondering if I'm going to have the same problem with a new one or not and wondering if it's even compatible with Airport Extreme routers.
I'm using Airport Utility version 6.1.
Can someone out there can let me know if they got this device working with their Airport Extreme?
Also, what are my other options to extend my range?

I know this answer is likely too late to help but it may help users in the future. In the situation where you are using a range extender there are a few things you need to confirm to make sure it is going to function properly and also some best practices to make sure your network is running smoothly.
1. Is the range extender using the router for DHCP? I have found in my experience is that the router should "reserve" a MAC Address and IP for the the Range Extender. Most times it is 192.168.1.2. I would first set up the router to have the range extender have a set IP Address of 192.168.***.2 and add the MAC Address to the list so that the Range Extender has a Static IP Address in the private network.
2. Initially set the range extender to have an SSID(Wireless Network Name) different than the Router's(Airport) SSID. This will allow you to determine if the Extender is functioning normally without it interfering with your existing network.
3. At this point it is important to set the Range Extender DHCP. What this will do is let the range extender request IP Addresses, DNS(Domain Name Servers), and UPNP Requests. This is where I feel that a lot of people are having issues and assume that the router will still resolve DHCP. If the SSID and Wireless Channel are the same your network will work intermittently with internet access until it is configured correctly.
4. For Devices that will stay on your network such as NAS(Network Storage), Smart TVs, Apple TVs I would recommend setting Static Private IP Addresses for each of them. Such as 192.168.1.3(NAS), 192.168.1.4(Apple TV), 192.168.5(Smart TV). Also if you enter the MAC Address for each device when you set this up it would be recommended.
5. If devices are having issues connecting to internet or certain web services are having issues. It may be necessary to set the Extender(Which is now handling DHCP with IP, DNS, and UPNP passed through from the router) as the Gateway for which device may be having issues. For instance if the Apple TV is having issues communicating on the network(Air Play, Sharing, Streaming) set or configure the network settings manually on the Apple TV. The IP Address would be the one your reserved on your router. The Subnet Mask would likely be 255.255.255.0 by default unless you have changed the amount of potential "Hosts" on your network. The Gateway would be the IP Address of the Extender(Which is paired with your router). DNS servers should be handled automatically. In some situations with certain devices you may need to use a DNS Service for Streaming, but this generally isn't needed.
A Visual Representation would be
ISP>Modem if needed>Router(DHCP Enabled and MAC Addresses Reserved)>Localized Devices<Range Extender(DHCP Enabled and Static IP Address 192.168.***.***)<Apple TV(Manually Configured IP Settings and Range Extender set as Gateway)<Other Devices Localized to Range Extender but not in range of Router(AirPort).
In this representation you should be able to have the router and range extender broadcast Identical SSID and Channels(Radio Frequency). This also allows for advanced settings to be put in place such as LAN networks or Subnets.
An issue that may come up is communicating with the range extender or router while setting up the network. A simple workaround that will allow you to configure either if the network doesn't let you connect on a MacBook is to go to System Preferences>Network>Wifi or Ethernet>Advanced>TCP/IP in configure IPv4>Set Using DHCP with Manual Address> Then IP Address that corresponds with your current network 192.168.***.*** but is not the same as the gateway, router, or reserved devices. This will allow you to connect and configure devices even if router or extender is not assigning IP addresses or operating properly.

Crashes with Airport extreme

I'm trying to set up a wireless network at home, part of which involves an external hard drive attached to the AirPort Extreme base. My iTunes library is too big to keep on the laptop, so it is on the external drive. When I'm listening to stuff through iTunes, everything seems to work alright for a while, and then iTunes locks up. I get a spinning pinwheel that goes on forever. If I force quit, it will be removed from the list of running applications, the window will disappear from the desktop, but the icon in the dock will have a little bullet next to it as if it were still running. If I re-open the force quit menu, iTunes will return to the list every time, even though there is no evidence that it is actually running. If I try to restart the computer, the whole thing freezes up and the computer can only be forced to shut down by holding the power button down. After the restart, iTunes continues to remain useless (if not crash-inducing) and the external hard drive is inaccessible. The only temporary fix is to re-setup the base station with the airport utility. No problems arise if the hard drive is connected directly to the computer. This problem has happened with each version of iTunes since the AirPort Extreme was released.
Here's what I got (from the wall out)
DSL modem (in bridge mode)
Airport Extreme (handling DHCP/NAT stuff, up-to-date firmware))
-printer and LaCie d2 250 gig HD connected via USB to Base Station
-First gen MacBook pro 17" connected via AirPort to Base Station (which I don't believe have airports that support the n protocol)
-AirPort Express (doesn't affect stability. the freeze-ups happen whether I'm on the network through the base station or the express)
help please
MacBook Pro 17" Mac OS X (10.4.10)

I have the same exact problem as you! I have been asking everyone on this forum for help about this, but nobody ever responds with an answer. I tried resetting my modem and router, and that seemed to help, but after copying files to different hard drives, I still get an error... after I check to see if anything copied, it actually worked! It never shows me the copy animation, all I get is an hourglass. When I try copying wirelessly to the same drive using my Macbook Pro, it works like a champ! I thought maybe the Airport Extreme doesn't work well with XP, but others say they have no problems. Should I reformat a partition of my hard drive to something that works better with the Airport Extreme?

Windows PC suddenly won't work with Airport Extreme

Anyone's help would be greatly appreciated. We had a storm this past weekend....had to reboot the modem and Airport Extreme. Two of the three computers were back on line with the Airport instantly: my G4 and a Dell PC. The third computer (my work computer and the one I'm writing this posting on) can't talk to the Airport anymore. Have never ever had a problem before. Getting "limited or no connectivity" status. Did "ipconfig" and not getting any reading on DNS Suffix or Default Gateway. My ISP won't help me because I'm not renting their wireless router from them. Please help! Thanks in advance!

Static IP-ed server with Airport Extreme 802.11ac

Howdy, y'all, In support of an app for remote users, we wanna expose a Win server using a static IP from our cable provider. The ISP has provided us with the static IPs, DNS IPs and a gateway IP. At the moment, the Win server is on a subnet routed by our new Airport Extreme 802.11ac receiving a reserved IP. If I configure the Win server with the static IP settings from the ISP, there's no Internet connectivity because the gateway IP is a different subnet. When I connect the Win server directly to the cable modem and bypass the Airport Extreme, the Win server has Internet connectivity. I suspect that I'll hafta use a separate switch between the cable modem and the Airport Extreme for the Win server. I think that we'll then have departmental Wi-Fi routed by the Airport Extreme. Any other suggestions? Thanks much.

Do you only have a single IP??
If so you cannot give that IP to the win server.. then you have no other network connection.. or internet from other clients.
But you can simply put the Win server with a static LAN ip set via dhcp reservations and then set the win server as the default host.. all packet incoming to the public IP are then passed to the Win Server.
DHCP reservation on the network tab of the airport utility.
Default host is under Network options.
You will still use the AE as main router and set wan to either dhcp which should work fine or the static IP.

How do I bridge motorola NVG510 to work with Airport Extreme

Hey everyone, I need some help.
I just got uverse and they sent me a motorola Nvg510 router. I need to put it under bridge mode so I can use the airport extreme and use the guest network functionality. I don't know what settings to put the motorola router and the airport extreme. Any help would be greatly appreciated. Please let me know if I have to provide any more information.
Thanks,
AC

I've put up a webpage to explain how to "force" the modem in effective bridge mode here:
http://www.ron-berman.com/2011/11/24/motorola-nvg510-help-page-for-att-u-verse-u sers/
(See question 6).
To get the IP address, just use what your NVG510 reports as "Broadband IPv4 Address" in the Broadband tab of its configuration page.
This address is mostly static (hasn't changed for me in months), and will only change where AT&T make a physical change on the line.

Can I use powerline wireless adapters with airport extreme

can I use power line wireless adapters with airport extreme?

Can this work?
Yes
I read somewhere that powerline adapters are not compatible with Airport.
That information is not correct.
If the AirPort Extreme is already set up as your "main" router, you would connect a short Ethernet cable from one of the LAN <-> ports on the Extreme to the power line adapter.
Locate another adapter in the area where you want to use the AirPort Express and connect a short Ethernet cable from the adapter to the Express.
Configure the Express to "create a wireless network" using the same wireless network name, same security settings and and same password as the AirPort Extreme network and select the Bridge Mode setting for the Express so that it work correctly on the network.
