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.

  • Apple Base Extreme 802.11n and HPC6100

    Ever since I replaced by old Apple Base Extreme 802.11g router with an Apple Base Extreme 802.11n router, my HP Photosmart C6100 can no longer print wirelessly. Since nothing else has changed, I fear that the C6100 is incompatible with the 802.11n router. Can anyone confirm this for me please and suggest any alternatives? Of course, i do not want to buy a new printer. Nor do i want to go back to an 802.11g router ....

    From a Wi-Fi (802.11) point of view, all of our recent wireless inkjet printers are compatible with the 802.11g standard and should work just fine with the 2.4 GHz band of the Apple Extreme wireless-routers.
    The last point is important.  The newer Apple Extreme wireless-routers are dual-band.  They can operate on the 5 GHz and 2.4 GHz 802.11 Wi-Fi bands.  While Apple's newest wireless-routers can operate simultaneously on the 2.4 GHz and 5 GHz bands, their older base stations operated on 2.4 GHz or 5 GHz.  So as long as the base station is operating on 2.4 GHz, our wireless printers will operate just fine.
    BTW -- that's the importance of buying Wi-Fi equipment that is Wi-Fi Certified (look for this logo).
    As for which of our printers are compatible with the USB port on Apple's wireless-routers, I'll have to defer that questions to others.

  • 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.

  • About My New Apple Airport Express 802.11n Wi-Fi Router

    Yesterday on Saturday after i finshed work I Went out & Bought a New Apple Airport Express 802.11n Wi-Fi Router for My Apple iMac Computer & for My Apple iPhone 5 & Apple TV & I Set it up & everything & everything worked out well so i had a question about it, that Green Solid New Light on Apple Airport Express is it suppose to always stay on even if my Apple iMac Computer is Sleeping like other Wi-Fi Routers??? cause i'm wondering cause it looks Very Nice & White & Shiny & New & i don't really want it to Fail on me cause i do like it & it does not take up a lot of space witch is a good thing so just had to ask???
    how many years will My Apple Airport Express Wi-Fi Router will last for since it's as Big an an Apple TV, just was wondering if this thing is really strong & stuff to like hold out for years time maybe???
    will My Apple Airport Express Wi-Fi Router Software ever get Outdated like my other Wi-Fi Router??? & they stopped making that Belkin Wireless n Router that i had & they stopped Updating it's Software & then The Software became not usable at all so I Had to go out & buy an Apple Airport Express 802.11n Wi-Fi Router.

    Hi Byron,
    on the first question: take a look at your manual; I have a different router, and on it the light stays on all the time, but I don't know if the Airport works the same way. On mine, it simply means that it is on and ready in case you need it. You should worry when there is no light, LOL.
    Second question: with electronics, can't tell at all how long they will be good for. They are made to be compatible with a certain range of devices and software - and will be updated for a while when those devices and softwares are updated. After a while, too many new routers are available with too many new features that are compatible with new devices and softwares, so it's not worth updating the old ones. It's a question of money - they don't want to give you free updates forever, they want you to buy a new piece of equipment.
    Third: yes, it will at some point. Everything technology/electronics related is outdated - some very quickly: you buy a new one and the next week you see an ad for a "new, improved" one. Same principle: they want you to buy again.

  • 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.

  • Apple TV refuses 802.11n

    Howdy folks...
    Bad week for Apple products for me. I went through two iPhones and now my Apple TV has decided to downshift! In the middle of watching a movie, the screen went black and came back with "Your iTunes Library is unavailable, make sure *computer name* is on and iTunes is open". I went over to the main computer and sure enough, iTunes was on, open, there were computers showing up in the shared section, but the Apple TV was missing under Devices.
    I'll describe my setup:
    I have a main file server in the house with the master iTunes library, it's the only library Apple TV syncs with. Connected to the server's ethernet port is an Airport Extreme N in bridge mode (one of its LAN ports), also, there is an 802.11 G "UFO" Airport connected to one of the spare LAN ports on the new Airport (this is the primary base station that is connected to my modem). I designed the network this way so that I can get the full 802.11n speed to my 802.11n devices (black MacBook and Apple TV), and other 802.11g devices would have their own portal into my file server. All Macs in the house run OS X 10.4.10 with iTunes 7.3.1 (I'm a freak about versioning)
    I navigated to the Network section of Apple TV's settings where I noticed it was no longer connected to a wireless network, and in fact wouldn't scan or display ANY networks (there are about 25 within range of my apartment that I ALWAYS see), so there was no possibility of me rejoining my network, even manually. I realized the situation was crappier than I thought and would require some hard-resetting and restoring. Here's everything I did:
    Factory reset Apple TV
    Factory reset BOTH Airport Extremes (G & N) and set them up with NO security
    Reinstalled iTunes, re-imported entire library
    Turned Syncing off, then back on (I could only enter the pairing code when joined to 802.11G)
    I discovered that after the restore, the Apple TV's Network utility on first boot would see my base stations! However, it would only join the 802.11G network, it continuously errored out when attempting to join the 802.11 N network (either -6, -3 or 0 as a code, which I couldn't find documentation for). Mind you, my MacBook can join my 802.11 N network with no problems at all, both before and after the factory reset of the base station. After I got the error code, and I went back to try and join my 802.11 G network, all the within-range networks were gone, and the scanning no longer worked as I described above. So I had to factory restore AGAIN. When the Apple TV came back up, I joined my 802.11G network with no issues, the Apple TV popped up in iTunes and began to sync. I cancelled the sync and ran the Software Update to get me to ATV 1.1. When it rebooted, I tried to switch networks and got the same loop of errors - try to join N network, fail, then no networks at all are displayed.
    Does anyone have any further recommendations for troubleshooting, or is the wifi card in my Apple TV fubar? I'd imagine that would be covered under the 1 year warranty, but since I got the Apple TV on launch and more than 90 days has passed, AppleCare refuses to speak to me (an ex Apple employee, a current Apple certified technician, in the Apple Consultants Network, and Apple Store business liaison for small/medium business in the Bay Area....what nerve!) even though I never used my "one phonecall".
    I've been really disappointed with their customer support as I've seen many of you on the boards have been as well, so hopefully we can help each other!

    I know it's a lot of work, but you could try setting up your network and tv again, using entirely different criteria, ie new network names, device names and passwords. I'm not guaranteeing success, but I have seen networking devices behave as though they remembered passwords and names after a reset and have conflicted with a new set up using the same passwords/names etc.

  • 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....

  • 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.

  • 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.

  • Having both 802.11g and 802.11n devices on a new dual-band AEBS

    Although I don't own a dual-band AEBS yet, I'm thinking I might be in the market for one. I just moved into a new apartment complex where the 2.4GHz frequency is saturated with over 30 wireless networks in range of my unit. I'm thinking that the 5GHz frequency would be much less crowded, and am thus considering getting a dual-band AEBS.
    I have the following equipment on my home network:
    1 Power Mac G5 (uses wired ethernet)
    2 MacBooks (use 802.11n)
    1 iPhone (uses 802.11g)
    1 PlayStation 3 (uses 802.11g)
    My question is (and I keep finding conflicting information on this topic) will the iPhone and the PS3 slow down the MacBooks from 802.11n speed to 802.11g speed when they are connected to the dual-band AEBS? If so, can this be avoided by running 2 routers with two separate SSIDs (one in 802.11n only mode, and the other in 802.11g only mode)?
    Sorry if this is a repeat question, but the fine print on Apple's product page says that the dual-band AEBS will be slowed down when a 802.11g device joins, but I have heard people say otherwise elsewhere.
    Thanks.

    So with the new dual-band AEBS, it is possible to create two different SSIDs (one 5GHz 802.11n and one 2.4GHz 802.11g) and have those two networks seamlessly joined for file/printer sharing as well as both run at their maximum speeds.
    To the best of my knowledge, being that I just got one a few days ago and haven't "experimented" fully yet, I believe the answer is yes to all counts. I'm sure if others have had the opportunity to check out all of the features that this new model has to offer, they will certainly chime in.

  • 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.

  • 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).

  • 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.

Maybe you are looking for
