Using AE for dual-band setup

In the Designing Airport Networks book they show using a couple of Extremes or one Extreme and one Time Capsule for setting up a dual-band network.
But would it be possible to use one AE bridged with ProxySTA and connected wired to an Extreme and do the same thing?
thanks

Not sure what you mean by that.
To create a dual-band network all you need is one 802.11n base station and one 802.11g base station. They can be from any manufacturer. The trick is to disable the DHCP server on the base station not directly connected to the internet.

New Time Capsule: Ideal Configuration Advice needed for dual band

I am updating/changing my wireless network to incorporate a 2TB Time Capsule instead of an Airport Extreme (not dual band but 80211.n). I have 2 old Airport Expresses (80211.g) that I will replace with newer 80211.n versions for AirTunes and wireless printing. My Airport Extreme still works and can also be used to extend the network.
I want to set up the new version of the network to use the dual band wisely given the items in my household that will be using it. I’m afraid I don’t quite understand what the ideal setup would be and hesitate to dismantle my currently working system before I’ve mapped out what I ought to do for the new one.
The wireless items that need to use the network:
MacBook Pro (circa 2007, Intel)
(needs to be backed up on Time Capsule daily, holds the large iTunes Library & large iPhoto library)
iBook (circa 2004)
iPhone 3GS
Wii
LG blu ray player
(n compatible... not currently in my network but will be added once the new network is up and running... hoping to use it to wirelessly download HD movies at 720p at least)
AirTunes (2 systems, using Airport Express units)
Canon printers (2... not wireless themselves but using Airport Expresses... I have 2 old Expresses or I can use the Extreme or the TC or piggy back on one of the Expresses that is supplying AirTunes)
TiVo series 2 DVR wireless connection (I do not know if this is n or g compatible. It’s several years old so I suspect g.)
Can someone point me to documentation that will help me understand my choices and possibilities, not just the technical how-to? Is there an ideal setup that's obvious to those of you with experience?

Hello KristenLC. Welcome to the Apple Discussions!
There are a number of things to take into consideration when "designing" a network. One of them is the bandwidth requirements of the network clients. Staying with this topic and based on your hardware: the MacBook Pro (Time Machine backups), LG player (Video streaming), & TiVo (Video streaming) will all require the most bandwidth. Streaming audio to the AirPort Express Base Stations (AXn) would most likely be the next in line for bandwidth. The iPhone, Wii, and iBook would probably require the least.
As such, you want to place your networking clients on the appropriate network infrastructure that would provide them with the best bandwidth possible for their needs. Ethernet will provide the best bandwidth, followed by 5 GHz 802.11n, 2.4 GHz 802.11n, and then, 2.4 GHz 802.11g.
So with not knowing where the desired location of your hardware, I can only recommend the following:
1) Connect the MBP, either by Ethernet or 5 GHz 802.11n, to the Time Capsule (TC).
2) Connect the 802.11n AirPort Extreme Base Station (AEBSn), by Ethernet, to the TC.
3) Connect the LG, either by Ethernet or 5 GHz 802.11n, to either the TC or AEBSn.
4) Similarly, connect the TiVo, either by Ethernet or 5 GHz 802.11n, to either the TC or AEBSn.
5) Join both AXn to either the TC or AEBSn by 5 GHz 802.11n.
6) Connect the iBook, either by Ethernet or 2.4 GHz 802.11g to the TC.
7) Connect the iPhone by 2.4 GHz 802.11g to the TC.
8) Connect the Wii, either by Ethernet or 5 GHz 802.11n, to either the TC or AEBSn.
Can someone point me to documentation that will help me understand my choices and possibilities, not just the technical how-to?
One excellent source would be from the Take Control series of guides. In particular, I would recommend that you check out: "Take Control of Your 802.11n AirPort Network" by Glenn Fleishman.

Configuration for dual-band WLAN?

I have an X230T with Intel N-6205 and 2x2 antennas. AFAIK it is capable of parallel WLAN connection on both the 2.4 & 5 GHz for maximum bandwidth. How should I configure my WLAN to take advantage of this. Should both 2.4 and 5 GHz networks have the same SSID?
X320T running Windows 8 Pro x64

Actually, those settings I provided you are from my Intel Dual Band Wireless-N 7260 adapter so some settings are a bit different, but it should work for all Intel Wi-Fi cards.

"I also have a secondary router, whose 2.4GHz radio I had set to 20 MHz BW, as there are more other 2.4 GHz WLANs near it. ISTR reading that the narrower BW can actually yield improved throughput under such conditions, and the secondary router has no "auto" BW option. What do you think of this?"
P.S. If I understand "NS offload for WoWLAN" correctly, it seems to be enabled.
At least, the WLAN adapter appears to turn itself on, even with the laptop powered down and connected to a wired ethernet.
As billbolton pointed out, he is 100% correct that "The 2.4GHz WiFi band has become so congested with competing traffic in many densely populated locations that useful 300Mpbs connections are quite unlikely to be achieved."
Based on many networking articles, 300 Mbps is achieved through channel bonding (40 MHz) on both bands. Since channel bonding makes the channels wider, this would actually result to more overlapping with other channels from routers nearby on the 2.4. Channel overlapping should be avoided since it induces more interference thus making your ping spike often as well as frequent reduced throughput and link speed. On the worst case, you will experiece dropped connections. If you absolutely have to work on the 2.4 GHz band with a lot of neighors, you can leave the Wi-Fi adapter settings I provided to be the same, but you have to change the channel width on the router to 20 Mhz only for 2.4 GHz band and leave the 40 MHz channel width on the 5 GHz band. This would cut the speed to 156 / 150 / 144 Mbps on 2.4 GHz band only, but you only occupy 2 adjacent channels from the channel you're broadcasting instead of taking over more than half of available channels using 40 MHz. Like many networking articles online, 40 MHz is ideal for 5 GHz since very few people use that band and there are far more available channels to choose for the 5 GHz without overlapping with other channels nearby.
As for your PS note, the reason the WLAN adapter is awake while the computer is asleep is due to Intel Smart Connect Technology: http://www.intel.com/content/www/us/en/architecture-and-technology/smart-connect-technology.html

Looking for dual-band option in Time Capsule

I read with great interest the on-line article in Macworld that described the improvements with this week's AirPort updates because I run two access points in tandem: An old Linksys 802.11g device for my "legacy" systems, and an Apple Time Casule (configured to 802.11n at 5 GHz) for my newer systems. So I immediately updated the AirPort software in my 5-month old Time Capsule and the AirPort utility on my Mac so I can use the Time Capsule in dual-band (simultaneous 2.4 and 5GHz) mode so I can simplify my network and honorably retire the Linksys.
To my surprise, I find that, after updating, there is no difference in the configuration options for my Time Capsule; I seem to be limited to EITHER 2.4 GHz or 5 GHz operation. Is there a setting that I'm just not seeing?
If anyone could shed some light, or provide a "how to guide," I would be most grateful.
Thank you.

Sorry, Simultaneous Dual-Band is an option available only to the new hardware (SKU MB763LL, 764LL,765LL).

Best prepaid carrier for dual-band iphone 4s A1387, unlocked by AT&T?

Hello -- I acquired a fine 16gb iphone 4s A1387, which is supposed be a "dual band CDMA & GSM world phone."
It was formerly on AT&T but has been unlocked by AT&T.
Do I have the best of both worlds? Can I go on either a CDMA or GSM network?
What would be your recommendation for a prepaid plan? My preference is to buy a block of minutes and GB good for an extended period, rather than a monthly plan.
How can I set up this phone to switch to wifi for Internet access when wifi is available?

If the phone was originally set up for AT&T, it can only be used for other GSM carriers. It cannot be used with Verizon or Sprint as they require the phone be in their database in order to be used - and they do not allow you to bring your own phone.

Best way to use Airport Extreme dual band with Netgear FR114P?

Years ago a friend connected via ethernet our G4 (10.4.11) and an old Blueberry iMac (10.4.11) to a Netgear FR114P Router(?) which is connected to a modem from TimeWarner Cable on our second floor. We also have an ethernet connection downstairs for a Windows XP laptop. We can all get on the internet easily, but we have never been able to connect wirelessly or to let one printer serve everyone in the house. My grandchildren now all have these wonderful Apple devices (iPhones, iPads, iPods, Macbooks), and I would like them to be able to connect wirelessly, and I would like to have a real network so we can all use the printer and scanner, but still preserving the integrity of our hard drives. We just bought 2 refurbished iMacs, an Apple Extreme Base Station (dual), and an Apple Express access point. How best to proceed to achieve the desired outcome? If the language is not too technical, I think I’ll be able to follow the directions.
I am reluctant to mess with the Netgear connection which is working. I am hoping I can remove the hard-wired G4 and put the 27” iMac in its place. Then, I am hoping I can connect the AEBS to the Netgear router and somehow magically create a situation wherein all the computers & some of the devices can talk to each other and to the peripherals wirelessly? Is that possible? I’ve read some of the discussions, even one about a Netgear FR114P, but it was dated 2007 so I’m not sure it applies to my situation. Should I just get rid of the Netgear? I don’t want to spend 20 hours without any kind of internet connection and get into a frustrating situation as one of the previous writers did. I am happy to proceed methodically and get it right the first time. Thanks so much for reading this long-winded thing. If this problem is already recently addressed in this forum, perhaps you will be kind enough to give me the link.

Grub/boot using wrong monitor (dual-head setup)?

I have a dual monitor set up, using two dvi slots on my radeon HD card.
When I start up my system, regardless of the order of the cables, it first shows my bios slash screen on both monitors, then it goes to Grub2 and I see "Loading Grub.." on both monitors. After that, it always defaults to displaying on my "secondary" monitor, which I do not use very often. Meanwhile my primary monitor goes black until my system reaches the SLIM login.
Is there any way to define which monitor is to be used in Grub2 and during booting?
I'm thinking it the default display may be configured in the /etc/grub.d/00_header file but I have no idea how to edit that.
As I said, I tried switching the cables and also checked the bios and didn't see any settings regarding this.

Used 3g for me, original setup?

I have recently acquired a used 3G iphone, not in my hands yet. It is unlocked and has been jail broken, and also has the new OS4 system installed. My question(s) is, I do have an itouch 8g, with the OS3 already installed on the touch and computer, is there a way to re-set/wipe clean the 3G phone and then when I sync from my computer it will load the OS3? Also, if that can work, what do I do to unlock for a different country?
thanks...

Just connect to itunes and restore the ipod, when the restore is complete set it as a new ipod. Your problem must be resolved.

Dual Band (5ghz and 2.4 ghz) Wireless Network Config and Dropped Connection

Hi, I have an Airport Extreme (802.11N) and a Motorola WR850G (802.11A/B/G) that I'm trying to connect in a dual band setup - but something in my setup is causing the Airport to drop it's connection (before the connection is dropped - everything works great). After I lose connectivity, both routers show up in my list of wireless networks, the light stays green, but I don't have local or internet access. When I try to reconnect, the log on times out. Also, the Airport isn't displayed in the Airport Utility (light is green on the airport itself though). Unplugging and resetting the Airport Allows all computers on the network to connect locally and to the internet for a few hours until the connection drops again. While it is up and running, I have no problems streaming movies off the connected Airdisk, navigating the internet, and connecting both N and G devices to the network.
I'd love to hear from you if you've gotten a similar setup to work, and if possible, have you provide the settings you used to make this work. I've looked around quite a bit and haven't seen a detailed description of the process (even from the Apple documentation). Also, advice from anyone would be greatly appreciated since my wireless networking knowledge is pretty basic.
My configuration:
Time Warner cable modem connected to the Airport's WAN port. WR850G connected by LAN port to Airport's LAN port. Bridge Mode check box selected on WR850G. Airport setup for 802.11n (5Ghz). Unique SSIDs to determine which network is 'N'. Same password for both networks. My Firmware and utilities are up to date.
Computers/Devices on Network:
Two Macs with Airport Extreme N cards. A Vista PC with a D-link N card (only compatible with 2.4 Ghz so it connects to the G network). A Vista PC with a GB ethernet card connected to the Airport Extreme. Various other G devices like iPod touches and an old iBook. Airdisk connected to the Airport Extreme.
Thanks,

I removed the second router (Moto wr850g) and everything seems to be working smoothly. It must be some settings on that one that are causing the problem, but I haven't been able to get it configured correctly. I noticed there were some IP conflicts with my wireless wanting to use the old Moto router IP and trying to assign my Mac an IP from that router. Does anyone know specifically what needs to be disabled on a router in bridge mode? Since I have a third party router there aren't any handy wizards that can configure it for me.
Thanks again
