2006 WLC and 802.11N

I have a 2006 WLC with 6 1242 APs and was wondering what should I expect when I replace 1242 with an 802.11n AP.
i know that the new AP will not run at full speed but other than that, I don't know.
Any thoughts on this?
Thanks, Gary

So I can add an 802.11N AP to the controller
The only 802.11n AP you can use is the 1250.
BUT it will not run at the N speed, etc. Right?
You can enable 802.11n but because the controller has 10/100BaseTx speed then you have a bottleneck.
So what we're thinking is purchasing 1 or 2 of the APs and let them run on our 2006 WLC, knowing that i WILL not see the speed difference, etc until next year, when i get the new WLC.
You're not making things easy for me are you?
Ok. So you know when is your next financial bucket will come in. How about saving your money. 1250 in an office environment .... Hmmm ... I won't recommend it. Plus the 1250 requires 20.0 watts of power (because you are running 4.X firmware). SO you either use a switch that can pour 20.0 PoE power, a power injector or remove one of the radio modules.
If you get, for instance, the 1040 (aka baby "N") or the 1140 plus the 5508 then you can really run 802.11n.

Is it possible to get an IPv6 and 802.11n capable router?

I would like to upgrade my current wireless router to an one that supports IPv6 and 802.11n. I want to do 6in4 tunnels for IPv6 to Hurricane Electric for my tunnel service and I have computers that have 802.11n. Currently I have the Actiontec (Verizon) MI424-WR wireless router with 10/100 ports. Can I get this through Verizon? I know I can go buy a Wireless router that can provide this on the outside, but want to ensure that this doesn't mess up my tv services. I have the three services currently on FIOS. TV, Internet and phone. So the router controls the TV settop boxes also.

Well Verzion them selve has no plans to switch customers over to ipv6 capable routers right away as its hard to get on Wireless N router from them as well unless you are on a buisness plan.Now If you Turn off your wireless from the Verizon side and hook up a router switch to a open port on the verizon router\modem there should be no problem as thats how i do mine.Also there are only certain routers and that support Wireless N and IPv6 access and I will post some info here as well about that.
http://www.dlink.com/products/?pid=767 <<< Heres The Dlink one im using as Dlink and Cisco (linksys) are the only companys that support Ipv6 fully on certain models.
Heres another IPV6 Router >> http://www.dlink.com/products/?pid=737
only two i know of but was told there are two more dlink models that support it but i contacted dlink and they told that the two links i have posted here are the only fully compatible IPV6 routers availible.

New Mac Mini and 802.11n 5Ghz - Does it work?

Does anyone know if this works? It states that it is 802.11a compatible which uses 5Ghz so I am guessing it does. I don't want to have to use a third party internal card like I do now with a separate external antenna. Thanks.

I have a mac mini I purchased last week (late 2009). I run 5Ghz 802.11n only (there is a g access point in the house, but that's on another part of the LAN). I have an iMac and MacBookPro that connect to the 802.11n and the performance is great - almost half as fast as a direct USB connection - it simply flies.
However, the mac mini is abysmal. It connects fine - everything works, but I get hardly 1Mbyte per second., despite having full signal strength. This is the info in System Profiler:

X1 and 802.11n

Hi,
Im having real issues with 802.11n and my new x1 carbon.
After configuring the '802.11n mode' option to enable I sometimes hit speeds over 54mbs but mostly it settles around 19-36..
This occurs at home and at my workplace (Technicolor gateway router and cisco enterpirse 802.11n network respectively).
What gives. I have updated the wifi controller to latest drivers.

When the iPhone joins the 802.11n (b/g compatible network) in the 2.4GHz band, the network will drop down the speed a little to deal with the slower device (this is done automatically, you don't have to manually change it).
Alternatively, you can manually switch between 5GHz 802.11n and 2.4GHz b/g mode every time your iphone need to connect to the internet. But it's a lot of inconvenience.
The best way is to run all 802.11n devices in 5 GHz band, and your iPhone in a separate 802.11b/g 2.4 GHz band network. But this requires two base stations.
From your earlier post, I don't think you have two base stations needed to set up a dual-band network, and you will need to purchase additional new base station to set this up.

Mac Mini (2007 model) Ethernet and 802.11N dead

Wow, talk about frustrating...my 13 month old 2007-model Mac Mini just crapped out with a couple of issues. The Ethernet networking reports the cable is unplugged, even though it's not, and the 802.11 wireless networking won't connect at N speeds. Of my four Macs, this was the only one without AppleCare, so no warranty help to be had.
Anyways, to troubleshoot the system, I've verified that the Ethernet cable I am using provides connectivity on another machine, and that other machines in the same workspace can connect to the 802.11n router via "n" speeds. So it's not anything external to the Mac Mini.
I also booted from a different OS X version via external USB drive, and the Ethernet and Wireless "n" still display the same symptoms. So it sounds like hardware, since a software glitch shouldn't appear with a different boot drive, right?
Verify disk and repair permissions also performed, with no anomalies noted.
System Profiler shows the Ethernet port is there, but in following troubleshooting "cable unplugged" errors tips in another thread I tried removing it from the networking pref pane, and re-adding it, but Ethernet doesn't show as an addable option anymore.
I am able to connect via 802.11g, so the machine's not totally dead connectivity-wise, but as home theater media server, I am sure going to miss the rapid file transfer rates of Ethernet or "n" wireless.
So, before I write this machine off as crippled, can anyone think of anything else I might try to get Ethernet working again? I suppose a USB-to-ethernet dongle would be better than Wireless-"g", but it's still less than ideal.
On another note, oddly, several of my programs started complaining about not being registered, which is what lead me to try permissions and disk verifications. Pretty strange.
Any ideas appreciated.

Ah, you're right about the N not being supported. Color me stupid on that one...silly me assumed that since I'd only had it a year, and N was around on my other Macs purchased around then, that it was there, but of course the design was a year old already. I'll update the thread post to drop that part.
As for the cable, I sort of tried two other cables already. My actual setup is to run the Mini to a gigabit switch, then the switch runs a CAT6 cable 50' to the router. I used two different cables out of the switch, and then plugged the long run directly into the Mini. No go. I guess not a big issue to unplug the Mini and move it to another room. I'll give it a go, but take note that it's been working fine on this same cable/switch/router set-up for a year. Odd that it would suddenly change.
Thanks for the tips, I'll post back with results when I get home and can check it out.

Mac Mini and 802.11n

I purchased a Mac Mini 1.83GHz in late September. On this page:
http://www.apple.com/airportextreme/performance.htmlIt states that:
"Most currently shipping Mac systems support the next-generation 802.11n technology in the new AirPort Extreme Base Station. And AirPort Extreme is compatible with Macs and PCs using previous-generation 802.11a/b/g wireless technologies."
Does this mean that my mini is compatible with 802.11n?
Dean

I've been pretty disappointed in the performance / reliability of the AirPort on my Mini, so rather than fighting the good fight, I decided to give up and use a Macsense WUA-800 (very slick!) instead of the built-in. I'm looking forward to getting the new n-based AEBS one day to go along with an Apple TV.
My 2 cents anyway....

Apple TV and 802.11N Failure

I have been an Apple TV since the first shipment. I have 2 units in my AV network with an Apple Mini acting as a central computer that both units stream/sync from. My wireless is configured at 802.11N with Wide channels on via a 100mb Apple Airport Extreme. I run a separate 802.11B/G network for my other devices. I upgraded the Airport Extreme to the latest firmwares and everything was working wonderfully. My Apple TVs functioned as always no drops, no stutters, no sync issues, and no disconnects. I upgraded to the latest Apple TV firmware to get the Genres support for my video library (400 Plus Titles from my own DVD's). Now both units disconnect randomly. I have scoured the support forums and have tried all the suggestions of turning wide channels off, changing from the automatic selection to a fixed channel, and various other solutions. The only one that seems to work is switching and CRIPPLING my airport Extreme to work in 802.11B/G compatibility mode. This is unacceptable!!!! Now to watch my movies I must decrease my network performance by 2/3. I used to get 300mb solid with my Laptop (Macbook Pro), now I get luck to get 130mb. There has to be some discussion from Apple on how to fix this. It is an obvious problem with the driver that was upgraded in the last firmware patch on the AppleTV and it is obviously manifesting itself in 802.11N mode. Some people might want to say that it is the Airport Extreme that is the problem.. I would disagree. I have used a couple different packet sniffing tools to monitor my connection on my Macbook Pro working in 802.11N mode and I have seen no drop in connections, no drop / or loss of packets for periods of over 12 hours. During that same time both Apple TVs dropped over 7 times. Several of the drops were during streaming playback. Any suggestions or help would be grateful. Any response from Apple would be grateful .
Thank you.

Trying to determine if this is my problem...
I just received my 160GB Apple TV this past Friday (Apr 11).
I am running WinXP Pro with a D-Link DIR-655 802.11n network.
My AppleTV came with 2.0 software out of the box. I went ahead and upgraded to 2.1 (or whatever)
To sync my library for the first time, I went wired without a hitch.
When I added it to my TV in the living room, the problems started.
It would range from working perfectly for a short time (selecting HD Trailers would play right away), then it would go to start playing, then hang or take forever to fill the bar and just hang, to the most common...
Anytime I would select something that used the wireless network, including even checking the network connection (which showed full strength) the system would reboot itself. It happened so many times I was ready to take to the Apple Store for a replacement.
Then I read this post and tried 2 things, changed my router to "n" mode only, no change.
Then to "g" only, everything now works.
I wish the status screen on the AppleTV would show more information, I'm not even sure I am connecting at N speeds to begin with.
So, does this sound like a similar problem or do I have a faulty device?
Thanks.

More explanations about MESH and 802.11n

Hello,
I just begin WiFi installations and I have some existential questions.
I have 5 Cisco 1552-E APs. One of them is wired to LAN and act as RAP, the 4 others are MAP.
On each AP, I use 1, 6, 11 channels as 2,4GHz non-overlapping channels.
As I have a 802.11n network, I use 5GHz band with non-overlapping channels too. Because I'm in Europe and outdoor, I want to use 100, 112, 124, 136 and 140 channels.
But all the 5 APs have a MESH backhaul 5GHz link to connect to LAN.
Please clarify my mind, because I don't understand how it is possible for 2 APs, to communicate between themselves on a different 5GHz channel ??
Thank you,
Clement

There is a new model which has 3 antenna ports for the 5ghz and 3 antenna ports for the 2.4ghz. This allows you to use one of the Cisco mesh patch antennas for a longer backhaul shoot to the RAP or even a MAP. It's hard to say what you can do but that gives you more options.
Cisco Aironet 1552E/1552EU External Antenna Access Points
The Cisco Aironet 1552E/1552EU Outdoor Access Points are the standard models, dual-radio system with external antenna ports that are compliant with IEEE 802.11b/g/n standards (2.4 GHz) and 802.11a/n (5-GHz).

Macbook Pro Retina and 802.11n

My MBP can't connect to TL-WR740N wifi router with 802.11n standart, any tips on how to setup router for apple devices?

Canle modem off, Airport Extreme off. Connect the modem and the extreme with ethernet cable. Power the modem. Wait about a minute, power the extreme. Use Airport Utility (in your Utilities folder) to set up the extreme. Review directions for the extreme as that will help.

Linksys E3000 Wireless Router, Xbox 360, 5GHz and 802.11n

Please could someone help - I'm tearing my hair out!!
When I set up a 5GHz 802.11n or mixed a/n SSID, my XBox can't connect to it, even with security disabled. It just says can't connect to wireless network. It can connect to a 2.4GHz SSID as 802.11g (not n). I've already reported the issue to Microsoft and also tried all the obvious things (I work with computer networks) and nothing works. It can see the network after a scan and, if I disable security, it will even warn me that security is disabled, but it just can't connect. Tried everything I can think of, including different channel widths, channels, USB ports and static IP configuration, to no avail.
Here are the details:
Router firmware version: 1.0.04
XBox version: Elite
NIC: Microsoft Wireless N Network Adapter (black, two antennae)
I've reported the issue to Micrsoft Support and they're not sure what the problem is either.

Maybe it's a compatibility issue. You and this guy have the same issue. But I'm not sure if you guys have the same adapter.

Vista and 802.11n on AEBS

Hi,
I've been scratching my head over why I can't connect Vista to my new Extreme network.
I'm running a '802.11n only' network on 5ghz as it seems the best performing setup for my MBP.
Having installed Vista as a 'might need it ocasionally' thing using Bootcamp1.2 ( easy install and no problems) I tried to get onto my 'n' network.
Vista ses the network and prompts for password etc to connect (WPA2) but then says 'unable to connect to network' and diverts me to the usual highly helpful Help pages
The only clue I have to my problems is that Vista reports the network as a 802.11a network.
Does Vista on MBP actually have drivers for 802.11n ?
Any ideas people ?
Thanks
Pete
Macbok Pro C2D Mac OS X (10.4.9)

Vista reports the network as a 802.11a network.
That is probably because you have specified 802.11n only which operates on the same 5GHz band used by 802.11a.
Others have reported joy getting Vista (under Bootcamp) to operate, however I don't recall if they used the 5GHz band. I suspect not.

MBA 1 and 802.11n

I have an MBA rev 1 and just bought an iMac 3.02GHz. Both sit within 10 feet of each other and less than that of the Apple airport. I've just upgraded my internet connection to a 4Mb line and both are connected wirelessly. However the MBA rev 1 is pulling about 75kbps max whereas I'm getting 380kbps off my iMac (download speed).
Why is this? Is my MBA not connecting 802.11n and only b or g or can anyone suggest another problem?
Really appreciate any help - warranty is tuning out in less than 2 weeks..
Thanks!

No answers but FYI (anyone reading this) have since had the MBA looked at and there is no apparent problem with the wi-fi. Further testing reveals so many inconsistencies when comparing against my iMac. I did note though that in removing the MBA from one of those plastic clip on cases, did seem to positively affect the speed.

Apple TV networking and 802.11n

Do all apple TVs support 802.11N? I'm thinking about upgrading my home network and wonder if I will see a performance improvement with streaming media?
thanks

I upgraded from a g to an n network about a week ago. On the AppleTV, streaming worked just fine under g. The performance actually went down when I installed the n network. This was due to me using the default WPA2 encryption. I downgraded to WPA and performance went back up. I think it syncs a little faster with iTunes (both devices are wireless). And I think that downloads over the internet are a little bit faster, but not significantly.

Aironet 1252 bridge and 802.11n

Hi,
I have two Cisco Aironet 1252 that I want to configure as a point-2-point bridge. Now I want to know if this configuration supports the 802.11n protocol.
Regards,
Screech

Scott,
I found the following statemen in the release note of IOS 12.4 (25d) (http://www.cisco.com/en/US/docs/wireless/access_point/ios/release/notes/12_4_25d._JArn.html#wp291685)
802.11n HT Rates Apply Only to No Encryption or WPA2/AES Encryption
The 802.11n HT rates apply only to no encryption or WPA2/AES encryption. They do not apply to WEP or WPA encryption. If WEP or TKIP encryption is used, the 1250 series access points and any 802.11n Draft 2.0 clients will not transmit at the HT rates. Legacy rates (802.11a/b/g) will be used for any clients using WEP or TKIP encryption
Given this statement how do I configure AES encryption on the aironets 1252 that are configured in bridge mode as I do not see this option. If possible please provide steps using the web interface.
Regards,
Screech

Can I Use 802.11n Base Station and 802.11n AirPort Express in an 802.11 ac Time Capsule Main Base Station WDS Network?

I havea "wirelessly challenged" 2-story home and need to extend the range. Currently I have an 802.11n Main Base Station with an 802.11n Airport Express Remote. It's not getting the job done (upstairs connection is weak).
I am considering getting an 802.11ac Airport Time Capsule to help, even though I currently only have devices with 802.11n wireless connectivity (future-proof a little).
I an planning on setting up a Wireless Distribution System (WDS) Network:
1.) Setting up the Time Capsule as the Main Base Station connected to a Cable modem
2.) Reconfiguring and Setting up the current AirPort Extreme 802.11n as a Relay Base Station
3.) Reconfiguring and Setting up the current AirPort Express 802.11n as a Remote Station
I cannot "hard wire" one Base Statio to the other.
Will this work?

Will this work?
Unfortunately, no. WDS is a older, very inefficient way to extend the wireless network signal.
As such, newer operating systems like Lion, Mountain Lion and Mavericks do not even offer settings for this older WDS type of network.
In addition, the new Time Capsule has no capabilities to use WDS settings at all, even if you used a Mac with another operating system to try to set things up.
Even if it were possible to set up a WDS network, the speed on the network would be incredibly slow. As you know, WDS only operates at "g" wireless speed levels. Each "relay" or "remote" that you add to the network each cuts that bandwidth or speed in half.
With a WDS "main", "relay" and "remote", the network would be operating at about 14 Mbps......a tiny fraction of what the devices would be capable of providing normally.
