Interference Robustness

Hello.
The wireless phone in my house gets a lot of interference when standing around the area where the Airport Extreme is.
Is turning on the "Interference Robustness" a way of avoiding this?
My phone is a 5.8Ghz and I use the Airport in "802.11n (802.11b/g compatible)".
Also, does changing the Multicast Rate or the channel affects signal strength, range and interference?
Thank you.

Is turning on the "Interference Robustness" a way of avoiding this?
No. It raises the signal detection level used by the AirPort Extreme base station (AEBS) and would affect the sensitivity (range) of the AEBS. But it would not affect your phone's performance.
Also, does changing the Multicast Rate or the channel affects signal strength, range and interference?
Yes. Interference as seen by the AEBS. Not interference as seen by other devices.
My phone is a 5.8Ghz and I use the Airport in "802.11n (802.11b/g compatible)".
Are you certain that your phone operates at 5.8 GHz? That would be odd. The normal frequencies for phones are 900 MHz, 2.4 GHz, and 5 GHz. Some phones advertised as 5 GHz also use 2.4 GHz.
Is your AEBS operating at 2.4 GHz or 5 GHz?

  • No 'Interference Robustness', HELP!  ...?

    Hello,
    I've recently been given a MacBook Pro, with OS 10.6. It replaces my prehistoric-yet-lovable iBook G4, which was produced in 2003.
    I notice that there is no "Use Interference Robustness" capability in the new OS. (This was in the drop-down menu under the internet 'fan') I could use the old disks that came with my old iBook, and go back to the old operating system on the new computer, but it seems silly to go back to an OS from 2003 just to get internet.
    I have read a lot of forum posts, including the following:
    http://discussions.apple.com/thread.jspa?threadID=1196815
    I am currently working overseas. I've got 4 roommates, and when I try to change channels on the router it screws up their computers. I'll be traveling soon, and I can't lug around an airport to connect to every router I need to connect to. I'll continue to be in densely populated areas, where everyone has got a microave, cordless, router, etc. The new computer 'sees' at least 7 other routers in the apartments around me.
    My new MacBook is NOT picking up a signal, not even when it is inches from the router. (To be specific the fan is full: it asks for a router password then briefly connects, then when you try to click on a webpage it simply takes forever to try and connect then eventually times out.) My iBook, using the old operating system, picks up the signal clearly from the other side of the house. (The old laptop has just been sold, so I will have to give it and its disks up soon!)
    I know other forum contributors said that the old 'interference robustness' feature was only ever meant to be used with AirPort, but as many other Apple users have confirmed, my old computer never worked without IR, and I never had an AirPort at all.
    The router is made by Pirelli (not kidding), but it hardly matters, seeing as I'll be on the go.
    Is there any way I can change computer settings to fix my problem?
    This oversight on Apple's part seems like the perfect opportunity for a desktop widget or other 3rd-party program, but none seems to exist.
    I've been dreaming of a new laptop and OS for years, and while there are some cute features like Photobooth, at first glance 10.6 lags. There are some modifications that I would have expected to see in iTunes as well... but internet is like water or air if you've got to get work done!

    I could use the old disks that came with my old iBook, and go back to the old operating system on the new computer…
    Good luck with that thought. That's not doable. Your machine won't recognize anything that old. See Don't install old versions and Computer-specific builds for details.
    As for the wifi issue, I can't help, since I don't use it, so you'll have to await those gurus to pop in.

  • Interference robustness in firmware 7.5.2

    I upgraded airport extreme to firmware 7.5.2 and in Wireless Options I not find option Interference Robustness. Is in another place?

    I'm having that exact problem again. I can't connect unless I am within 3 feet. That does NOT make sense. It has been a problem in 2007, and there is a thread about the upgrades that ruined it for too many then. I remember before 2007, my websites were coming fast and I was blazing thru the net. Since 2007, the wireless connectivity was so-so until the update last month. Then I noticed that my Interference Robustness option disappeared. Since then, I had to walk back up stairs to my room to get it reconnected, then walk back downstairs every other hour. Now I have to be within 3 feet, so that's it I checked discussions tonight and then immediately created a new account to post a reply.

  • Connecting to wiresless network using Interference Robustness

    Is it possible to create an Automator workflow that will automatically on startup or login select "Interference Robustness" then select a specific wireless network?
    Thanks for any help or suggestions anyone can offer.

    When I boot up the mac the wireless connection doesn't automatically start. I have to manually turn on "interference robustness" then select my desired wireless network.
    Has anyone else experienced this issue and/or have a work around to solve this?

  • Where is "Use Interference Robustness"?

    Hello,
    i miss the function "Use Interference Robustness" in Mac OS X Leopard!
    Without this i am losing constantly my Airport Connections.
    Can anybody help?

    Interference robustness has worked well for a number of people not using Apple Airport base stations (such as myself). As it turns out, I have an Airport Express that my iMac under Leopard will not recognize only 2 feet away. Naturally, under Tiger all is still well.
    Moving interference robustness under the advanced settings is a real problem for people without Airport base stations as it is now impossible to get to the settings without recognizing a base station.
    For example, I had turned on interference robustness during the two minute window that my Airport Express was recognized. Now, since Leopard is so spotty (sorry for the pun), I can't reliably test whether or not that setting helps at all. That said, I can report that my basic internet connection was practically nonexistent prior to implementing interference robustness on my iMac G4.
    I'm surprised at Apple for this one - Leopard has been been through what seems like extensive testing, and this pops up! And no response from Apple ...

  • Use Interference Robustness?

    I'm temporarily operating in a place with a LOT of visible wireless access points. Airport is neatly automatically selecting channels, and I'm not noticing any problems, but I'm wondering about the "Use Interference Robustness" check item in the pull-down under the network selection place on the main menu bar.
    Can someone tell me what this does and how I might know if I need it? Any side effects? I've tried turning it on but I don't notice any change one way or the other.
    Thanks for any help!

    Link speed from Network Utility is 54MB either way, which is the best my MacBook and AP Express will do. Net Utility doesn't seem to have any real-time info on effective transfer speed. speakeasy.net/speedtest reported 800MB+ download, and 200MB+ upload, which I think is the most basic Cox Cable option in this area, and considerably less than the same hardware records at normal home base. Only a little use for peer-to-peer file sharing, so that's not a significant issue.
    Thanks!

  • Use Interference Robustness option disabling on restarts

    I don't know if this is a rare case, but I've been having a problem with the Interference Robustness option. I live in a under a lot of interference, so this option is vital for my internet connection to be as smooth as possible. Although, every time I restart my Mac, this option gets disabled. What can I do to alleviate the situation? Is this a OS X Tiger bug or something? It began to happen all the sudden after updating to the latest patch. Thank you.

    Anyone? Please help.

  • DROP OUT cure!  Make sure "Enable Interference Robustness" is Checked!!!

    I found the secret button - and now music plays like there's no tomorrow!
    Like - I spent at least three weeks - three different routers trying to get my music to stream without drop-outs - to no avail. Then finally I FOUND THE TRICK. Like duh! Read on.
    Here's my set up -
    3 Airport Express Boxes fed to three separate amps and speakers around the house
    1 Apple TV fed to the home theatre
    4 Laptops connect wirelessly to the Netgear
    1 NAS drive hardwired to the Netgear with all the iTunes Music on it
    All connected to 1 Netgear MIMO-G Router via WPA Security
    Man this was killing me - with all these variables I couldn't figure out why my music would play OK for a few minutes, then either drop out every minute or so for a few seconds - or just crash my router requiring me to kill its power for 2 seconds. This was killing me. I was about to give up on Apple and get a Roku.
    But alas - here's the cure
    THERE IS THIS LITTLE TINY CHECK BOX IN THE AIRPORT EXPRESS ADMIN UTILITY -
    ON THE AIRPORT TAB - UNDER THE BOX THAT SAYS WIRELESS SECURITY THERE IS A TINY BOX THAT SAYS:
    "Enable Interference Robustness"
    Click that - and you are in like slim.
    I found so many calls for help on this board for drop-outs that I had to just write this post. Good luck to all!
    G

    Ok, so all i got to say to this setup is wow you are a crazy man lol. First off storing your itunes library on a drive on the network is going to add more latency to your network as each time you try playing a song its having to go from your computer to the router, to the NAS drive, back to the router and then to the airport. However one thing i didnt see or maybe you may have tried i dont know is before using the enable interference robustness option did you try changing the wireless channel on the netgear router? Could just be something is interfering with the current wireless channel that its on. After tinkering with Interference Robustness myself ive found it to be like a Mass Blanket of wireless transmission. Think of you and another person being in a room with a crowd of people and your yelling back info back and forth. Sure you can hear and talk back to the person but your range to hear and speak is greatly reduced meaning if you wanna add any other wireless products that are outside that reduced range your kinda out of luck.

  • Mulitcast rate & interference robustness options?

    Is there any downside to setting the multicast rate of my new Airport Extreme N to the highest option and enabling interference robustness?
    I'm aware that the higher the multicast rate, the lower my range, but I'm usually in the same room as the router. Will this then improve my speeds when transferring large files to the usb-attached network drive or streaming music?

    Good question. Tuff to answer. Robustness will slow you up. If you don't have interference why use it. The downloads speed I would think it would not make a difference unless others were using your network.

  • Can't Enable interference robustness

    in Sytem Preferences-->Network-->Airport-->Options...
    The "Enable interference robustness" check box is greyed out and can not be selected. Also, the option "Remember any network this computer has joined" is checked, but is also greyed out. I also do not have the option "Enable interference robustness" in the Airport status menu bar at all.
    All the options are available and working on my wifes G4 ibook connected to the same base station.
    The option "Enable interference robustness" is checked in the base station configuration portion of the Airport Admin Utility.
    I've repaired permissions but the option is still greyed out.
    Any ideas?
    G4 MDD   Mac OS X (10.4.8)  

    Try the following, in order, until resolved:
    1. Create a New User Account
    - Create a new user account.
    -- System Preferences > Accounts
    -- Click "+" to add a new account
    - Log off, then log back on with the new user account.
    - Try connecting with the AirPort.
    2. Move System Configuration Files
    (Note: You will have to reestablish your network connections settings.)
    - Go to /Library/Preferences
    - Move the SystemConfiguration folder and com.apple.networkConfig.plist file to the desktop.
    - Restart your Mac. (Note: OS X will rebuild the files that are now sitting on your desktop. If this doesn't resolve the issue, you can move the folder & .plist file back to it's original location.)

  • 'Use Interference Robustness' option not showing in AirPort menulet

    On my 1.67MHz AlBook I get this option, second from the bottom on the AirPort menulet. Not so on my TiBook. Both running 10.4.5. What gives?

    Got you, many thanks, iFelix!
    What I still don't understand is: does it affect the
    Base Station's signal? or just the respective
    computer's card?
    From the Airport menulet, just the card.
    You need to use the Airport Admin Utility (wireless options) to enable it on the base station.
    And if it boosts the signal, how
    come it reduces the range?
    You can't boost the total power that a wireless card or base station uses.
    Therefore if you increase the signal you have to sacrifice range.
    If the total power was say 240, you could have strength 3, range 80 or strength 6 range 40.

  • Airport Express and outside network interference

    I have been having some difficulty staying connected to my Airport Express lately. I'm running a Power Mac G4 MDD (airport card) and an iBook 933mhz (airport extreme card), and an iMac (wired to a router). The airport express is also cabled to the router, which is connected to the cable modem. Everything worked fine from February to about 2 weeks ago. No dropouts or anything. The airport admin utility is set up as follows:
    -Wireless mode: Create a wireless network (home router)
    -WPA personal wireless security
    -Channel - 11 (I have experimented with all channels)
    -Mode 802.11b/g compatible
    Wireless options
    -multicast rate 5.5
    -interference robustness enabled
    -transmit power 100%
    The iBook, I noticed this evening, seems to be picking up an outside network. The power mac doesn't seem to pick it up though. Im thinking it has to do with the difference between the 802.11b card in the Power mac and the 802.11g card in the iBook. Although the two wireless computers drop the connection, I also noticed this evening, that the Power mac seems more susceptible to the dropout (the connection isn't always lost at the same time). I also have a difficult time reestablishing the connection. I'm starting to think my problem lies in the channel setting, except none of them seem to make much difference. What other options do I have to limit this interference????

    Jason
    first let me start saying that it might not solve your problem, however, I was told, by an Apple engineer in charge of the networking for an Apple event, that in case of a mixed network (b and g) set the airport to be b only. He gave me the reasons, but I can not remember.
    I used to have my network in b (I have a mixed setting), but since I have 2 airport xpress, one is set to "b" the other is set to "g".
    I have had no problems.
    Now, since I do not think this will solve your problem, you should check to see if there is any signal of an external interference going on.
    Do your problems happen more frequently at a certain times.
    Something new in the neighborhood ? So on and so forth.

  • Please help: Chronic Airtunes Drop-outs/2.4 Ghz Interference

    For several months, I have been battling interference with airtunes/AX, which is now so bad that it's barely usable. The music stops/starts constantly, and sometimes iTunes just stops. The signal strength indicator (normally 4 bars) jumps all over the place, going down to 3 and 2 bars. I used the same equipment set-up for over a year with excellent results until several months ago.
    Here's the setup:
    Airport Extreme connected to DSL router; Firmware: 5.7
    Airport Express1 connected to stereo; Firmware: 6.3
    Airport Express2 connected to USB printer; Firmware: 6.3
    The AXes are set up to join the Airport Extreme network
    3 Macs are on the network, and all experience the same symptoms. Powerbook1 (PB1) runs 802.11g; PB2 and iMac run 802.11b. PB1 has Interference Robustness enabled; the others don't support it. It seems to help slightly. No microwave or other Apple-defined interference source near any of the airport base stations.
    PB1 is 24 feet from Airport Extreme and 20 feet from AX1
    PB2 and iMac comparable distances.
    I've been at the Genius Bar and have tried these things at their suggestion, and none have made a perceived difference.
    -Turned off IPv6
    -In Airport Admin Util:
    --Changed channel from "automatic" to 1, 5, 9, 11 and others
    --Increased multicast rate to 11 and 5.5
    --Transmitter power 100%
    --Interference Robustness enabled here
    Thanks to Joe for suggesting Air Traffic Control widget to check your signal strength.
    http://www.apple.com/downloads/dashboard/networking_security/airtrafficcontrol.h tml
    It shows 2 neighbors on channels 1 and 6, so I put ours on 9. I hypothesize that it's a 2.4 ghz phone or other device.
    What more can I do?
    Thanks in advance for your help.

  • Possibly unique interference issue. Is TC the answer?

    I'm sure there are some similar topics on this forum, but I feel I may have a slightly unique issue...
    Let me start by saying I'm currently using an Airport Express, MacBook Pro 3.1, iPhone 4 and the new AppleTV. I, like many others, am having trouble with radio frequency interference. At night, I have a great wifi connection...during the day, however, I have no wifi and my Airport doesn't even show up in Airport Utility.
    I'm pretty sure I've pinpointed my problem. My apartment is directly above a hobby store that specializes in radio controlled toy planes, trains and automobiles. Radio frequency overload.
    I've moved my Airport around, messed around with different channels in Airport Utility and turned on interference robustness...still nothing.
    I realize I may be utterly screwed, which bums me out because I'd absolutely LOVE to use my AppleTV during the day, especially for music, but I remain hopeful. The question is: does Time Capsule have a much stronger signal? Should I ditch my Express for that, or are there more things I could try?
    PS: I don't want to layer my floor with aluminum foil!

    The strength of the Time Capsule signal would be the same as the AirPort Express, but it would have the advantage of using both normal 2.4 GHz wireless and 5 GHz wireless.
    There are very few wireless networks using the 5 GHz band, so that might be a possibility for you to consider. Newer computers would connect at 5 GHz, but the iPhone would not, so you would have to use the normal 2.4 GHz network for those connections.
    If you have a newer "n" AirPort Express that supports 5 GHz, you could try that as an experiment to see if it helps...and also check to see how many of your other devices can connect at 5 GHz.
    AirPort Utility - Manual Setup
    Click the Wireless tab below the icons
    Change the Radio Mode to 802.11n only 5 GHz
    Update to save settings
    You can always return to the previous setting by going back in.

  • Too Many Networks Causing Interference

    Hi all,
    I'm running a PB G4 and Toshiba Tecra laptop on a wireless AEBS + AE network using WDS in a first floor apartment. My signal strength throughout the house is usually full bars with the AEBS running at around 45-65 and the AE at 35-45 signal strength depending on what room I'm in.
    Now, sometimes my network just crashes and I receive error messages on the PB and PC telling me that there was an error loggin on to my network or that the connection is incomplete, respectively. My only recourse is to unplug the base station (and AE) and replug it. Usually, this corrects the situation.
    I think this is happening because I detect no less than 5 other networks in my area. There are four units in my building, and the building is part of a row of connected apartment buildings. Adding my AEBS and AE, this makes a total of 7 transmitters in this cramped area! I think this might be creating a wireless blitz.
    FYI, before running my current configuration, I was using a Netgear wireless router with the AE as a client (to stream audio). I switched to the AEBS + AE in WDS config because I thought it would add greater stability and range--which it has. But it seems I might need to "power up" some more in order to fend off the interference from other networks. I realize that this might have bad consequences for those other networks, but something has to be done!
    So, I've been considering boosting my signal by adding an antenna. Is this a solution? I'm also thinking about tweaking the settings for both stations through Admin Utility. Maybe enabling interference robustness on the AEBS, AE, and PB might help?
    Please offer any advice on what you think the problem might be and what might be the best solution.
    Thanks,
    FC

    I don't think so. You'll increase your signal
    level, and your noise level all together. But
    your signal to noise ratio will reach a limit.
    Exactly like what happens when you turn your radio
    too loud because of the noise of your neighbour's
    one.
    I'm also
    thinking about tweaking the settings for both
    stations through Admin Utility. Maybe enabling
    interference robustness on the AEBS, AE, and PB might
    help?
    Yes.
    But more generally, like every wireless problem of
    interference, you should first analyse it. You
    should use a tool like iStumbler to identify all
    the channels used by your neighbours.
    Once you have identified these channels, and
    their level of signal, you have to choose a channel
    as far as possible of the most powerful ones.
    In an idealistic world, you should choose a channel
    3 channels away of all the channels used by your
    neighbours. (e.g.: if channels 1, 2, 5 & 6 are used,
    you may use channels from 10 to 14, depending on the
    regulations were you're using a wireless network).
    All interference analysis should first go through
    this neighbour's channels hunt.
    If you play randomly with your channels, you're
    wasting your time, you may be disrupting your
    neighbour's networks. And you will have to continue
    this silly danse for a long time all together.
