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!

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.

Do I need to replace my modem/router to improve Airport Extreme performance?

Hi all.
Until recently my home network consisted of an ISP-supplier Thomson TG585 wireless router supporting both a MacBook Pro & iMac.
The config. worked to a point. Both machines could get to the web fine, but frustratingly would rarely "see" each other via the router. No problem when directly connected via LAN cable.
I have an external office some 20m or so away from the house and therefore need to use the MacBook at a distance. The TG585 failed to give the range required so I improved coverage by adding an Airport Extreme as a bridge (the Macs now see each other fine).
Whilst a great improvement in coverage, on occasion though it slows right down and even drops out.
I've loaded iStumbler to do some checks and whilst there's a number of domestic networks in the neighbourhood, none are on the same channel and all are running at 2.4Ghz, so presumably the Airport should be fine given its dual frequency capability?
iStumbler's indicating though that at the range I'm operating the signal range drops to between 15-25% and even with the MacBook right beside the Extreme it only gets to 61%. Both seem a bit low.
I'm no network expert, but this seems to suggest to me that it is the level I'm getting, rather than any interference which is the issue?
My first thought was to try and boost the MacBook's reception capability with an external USB aerial (looking through the forums the Asus USB-N10 seems to be a good choice).
In discussing this with local retailer however, he suggested this is the wrong idea. My problem apparently is the poor capability of the TG585 which is providing a reasonably weak/variable signal to the Extreme. Instead, I should be swapping out the TG585 for a more sophisticated router (his suggestion the Linksys E2000). With the base router providing a strong 5Ghz input then this enables the Extreme to perform at its best.
My question (finally!) is whether this is indeed the case (i.e. modem replacement req.)? If so, I don't want to replicate the Airport Extreme's spec. so I'm interested in any suggestions on a suitable modem(router) for this instance? If I have to splash out on a dual freq. modem/router in addition it starts me questioning the wisdom of my choice to buy the Extreme.
PS: Sorry it's a long one; thanks for taking the time to read.

I am afraid that the interference that you are picking up is coming from outside sources. Unfortunately, you will not be able to do much about this other than try different locations for the AirPort Extreme.
I'm assuming that your AirPort Extreme is not located close to a televison or other electronic device. If it is, try to move it as far away as possible. Also try to keep it as far away from any outside walls or windows in the apartment as possible.
I was helping a friend recently who moved into a a new high rise apartment/condo development and we found that he simply could not use 2.4 GHz wireless reliably in his area due to the number of other networks and interference issues. That is likely the case in many other situations due to the explosion of wireless networks in the last few years.
For your reference, the most accurate way to judge signal quality is Signal to Noise or SNR.
Hold down the option key on your Mac and click on the Apple icon in upper left corner of the screen
Select System Profier.
Look down the list for the Network heading and then click on AirPort to highlight it
Look in the window to the right for the name of the wireless network, then look for the Signal / Noise readings. These will be negative numbers. Example: Signal / Noise -60 dBm / -80 dBm
SNR = Signal minus Noise, so -60 dB - (-80) dB = 20 dB
Then use the reference chart posted by expert user Tesserax to get a general idea of the connection quality
o 40dB+ SNR = Excellent signal
o 25dB to 40dB SNR = Very good signal
o 15dB to 25dB SNR = Low signal
o 10dB to 15dB SNR = Very low signal
o 5dB to 10dB SNR = No signal
With only 10 feet between the computer and router, you definitely should see 40 dB+ readings under normal conditions
How does your signal look if you use this method?

ADSL2 gigabit modem to go with airport extreme?

Just about to go back to using an Airport Extreme, but as I'm in the UK I need an ADSL modem for it. I usually just use the router that came with my O2 broadband and just switch off it's wifi. But ideally I'd like to find an ADSL2 gigabit modem. Tried googling, but all the ADSL2 modem's seem to be 10/100 ethernet, and I don't see the point in buying a gigabit ADSL2 wireless router. Any suggestions?

I'd think a 100 Mbps port would be faster than just about any ADSL data stream. Gigabit would be overkill. The usefulness of a gigabit router would presumably be in transferring data between devices on the LAN.

Recommended Modem to use with Airport Extreme

I currently have AT&T DSL. It is connected to AT&T's really crummy 2Wire 2701HG-B modem/router combo. I want to ditch the 2Wire and replace it with the Airport Extreme router, but I am told that I will also have to buy a modem to hook up to the router.
Any recommendations on a good modem that is compatable with AT&T DSL, and plays nice with the Airport extreme?

Best to check first with ATT for modems that are compatible with their service and will be supported in the event of connection difficulties.

It looks like the Motorola 3360 might do what you need.
I have the previous version model....a Motorola 2210.....that has worked just fine for 4+ years with my AirPort Extreme.

What's the best ADSL modem to use with Airport Extreme?

My current set up includes an 802.11n Airport Extreme (that I use in conjunction with my Apple TV and MacBook) connected to my Netgear DG834G wireless router (wifi is switched off). The Netgear router is connected by ethernet to 2 Macs, a Skype phone, and my laser printer.
I want to upgrade my LAN to gigabit, and I'm not sure whether I would be better to use a Gigabit switch instead of connecting everything via the router, or whether I should buy a new router which supports gigabit?
Also, I've just been reading about the DrayTek Vigor 100 ADSL2+ Ethernet Modem, and it suggests that it's better to have a separate modem rather than a router. All I know is that in the early days of broadband the USB modems connected to one computer were very unreliable, and that a router was far better.
What is the best way to configure such options? When I first got my new Airport Extreme I found that both it and the router were 'competing' with each other. Is there anywhere to turn to so I can get a better understanding of how to configure these things.
PS. I know my Airport Extreme doesn't have gigabit - but I've just ordered the newer version that does.

I use the Linksys ADSL2MUE - which I managed to buy for £12.
I configured it in bridged mode - leaving the Apple Extreme do all the firewall and DHCP stuff.
It's not pretty but does the job.

Modem for use with airport extreme?

I know that the AirPort Time Capsules do not have a built in modem and I need an external one.
I also have ADSL internet as opposed to Fibre so I need to find something suitable to sit between the Time Capsule and the interent. I realise that I could simply use the modem / router supplied by my ISP and switch off the wi-fi on that and just use the modem aspects, but this uses an additiional power source.
My question is: Is there a suitable modem that will sit between the AirPort Time Capsule and an ADSL internet connection that does not need and additional power source?
If not (and I suspect there isn't as I can't find one), then is there any benefit in having a independent modem only device over using the ISP supplied modem / router and switching the router aspects off?
Thanks for any advice as I am having a real nightmare setting up my third party modem / router to work with an Apple network with some additional non-Apple devices and feel that going down the all Apple route of an AirPort would just make my life so much simple...

PPPOA is the big issue..
You cannot bridge to a modem running that authentication. There is no client that will work so the Apple has to be in bridge.. or some dicey double NAT setup.
The Thomson/Technicolor offers a dhcp spoofing but it goes through the NAT and it also causes heaps of issues.. Thomson modem routers have the worst possible NAT called full cone. You must manually bind all UDP ports to the NAT to get access.. and even that is not workable for many functions.
So you are quite right.. it is a mess.
Hence my thought to switch to an Apple router as it automatically opens relevant ports and recognises Apple devices. I have no idea (at this stage) how to set up a router / modem or bridge or other device to sit between the Apple AirPort Time Capsule and the ADSL internet connection.
Using the Apple router to open ports, is not going to help.. because you cannot bridge the modem.
So where do you end up.
The reason I am struggling with my Asus DSL-55n modem is that it is just too complex for me to get to grips with and there is little in the way of support documentation from Asus to assist me is overcoming the specific difficulties I have been having.
What issues are they?
I do not particularly like Asus modems.. they are generally poor firmware.. but have you loaded in the latest firmware.. check for updates because they have been improving.
A solution might be the Draytek 120 modem.. it has a neat little trick where you do PPPoE to PPPoA on the modem.. there are a few that can do it but the only readily available now that I know of is the draytek.
There is a mode in the Thomson called PPTP to PPPoA relay.. this also works very well but Apple do not support these more esoteric connections.. it is better used on a third party router.
If it makes any difference at all, my ISP allocates me a static external IP address which I have paid for and is automatically pushed to whatever router I seem to use.
It is only significant if the authentication method is IPOA .. where you use the IP as static on the router and have no authentication.. but static IP for PPPOA simply means your public IP doesn't change.. useful and helpful but not a solution to this problem.

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

Time Capsule interfering with airport extreme?

Recenty my Time Capsule (first model) connected to my iMac Intel Core2Duo running 10.6.2(first model with that chip), has been having some issues. I just moved and when I tried to hook it up wirelessly, Airport Admin said there was an error connecting. There was no error number. I hooked it up wired via ethernet, and was able to configure for Time Machine and get a backup started overnight. After the backup was done, the Time Capsule went back to a blinking yellow light the next morning. The Time Capsule is set to connect to my existing Airport Extreme network. When it went back to a yellow light, my existing Airport Extreme network no longer functioned, even though it showed a green light. Next thing I knew I checked the Time Capsule, and it was green again. Shut off the power to the Time Capsule, and my wireless nework was operational again. Could my Airport Extreme network not like what the Time Capsule is doing? Or is it just coincidence?

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.

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?

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.
