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!

  • 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 ...

  • 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?

  • 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.

  • '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.

  • 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.

  • 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.

  • 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?

  • 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.

  • 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.)

  • Timezone interference with apointments?

    If I receive an appointment from my wife's Windows XP Professional computer (from Outlook) it automatically goes into iCal in the correct place.
    When I publish the calendar to dotmac, this appointment is positioned in the appropriate place but delayed by 7 hours. All other appointments made on my Mac transfer correctly to dotmac.
    Both systems sync time from the internet. They are both set up for the same time zone.
    When I send an appointment to my wife's PC it is not incorporated in her calendar automatically. When she clicks on the ics attachment she gets an error condition "cannot import vCalender file". The help for this indicates "cannot import a recurring Lunar event in iCalendar format. Set the apointment option to Gregorian instead of Lunar."
    As far as I can see, both computers have the Gregorian calendar set.
    Help!

    Have you tried turning on “Use interference robustness.” in your Airport settings? This is supposed to mitigate those types of issues.

  • Airport Express - Discontinuous Audio when used for streaming music

    I recently installed a new iMac with Leopard along with Time Capsule as the base station connected wirelessly to the iMac. Added Airport Express to this network and everything looks like it works after a couple of tries.
    When I play iTunes on the iMac and select the Airport Express speakers, I get a discontinuous sound. iTunes plays the music for 10 sec, stops for a few sec, then picks up where it left off...repeat endlessly.
    iTunes plays back fine on the computer's speakers.
    Any thoughts on how to fix the discontinuous music streaming ?

    1. Check to make sure that iTunes isn't hogging all of your CPU when it is running. If your CPU starts running at 100%, you will get audio dropouts. Make sure that unnecessary processes don't load at boot time.
    ok, cpu is fine, between 0 and 25% when playing
    2. In Quicktime, Edit -> Preferences -> Quicktime Preferences -> Audio -> uncheck "Safe Mode". If this doesn't work, then recheck. You should reboot to make sure.
    DOne, rebooted, undone, redone, nothing helps
    3. In Airport Express Utility, Wireless -> Wireless Options -> Check on Use Interference Robustness
    also done
    4. If you have a lot of wireless internet routers in your neighbourhood you can try changing your wireless channel. Netstumbler will show you what's going on in your area.
    tried all of the 13 channels!
    5. If using a router and your Airport Express is a client of your router, move the antennas on your wireless router. One of the antennae should be at a 45 degree angle from the router so that the two antennas don't cause a conflict with each other. (Imagine dropping two stones into a pool of water where the waves created by the stones are equal to the radio waves produced by your router; the waves hit each other and distort the path of each one; by moving one of the antennae on an angle, this conflict is avoided.)
    antennas turned as you told me, still not better
    6. In iTunes, you might try changing the following: Edit -> Preferences -> Advanced -> Change the buffer streaming to "small" (or one of the others).
    done, and also tried "medium" and "large"....
    7. If you are using a third-party router, and you are comfortable with changing the settings, and if you have this setting, you might want to try lowering or increasing the Beacon Interval.
    not familiar with this, what is a third party router? I have one main router for adsl and digital tv, + trying to get airport working for music...
    8. Of course, don't have a metal filing cabinet, or hollow tubes (yeah, even toilet paper rolls -- so no iTunes in the bathroom, please) -- as these would also interfere with broadcast.
    no interferences, no metallic cabinet, no toilets around lol
    what can I do more? give it back to the shop, buy a MAC computer instead of my pc? I think I'm going to give that thing back to the shop....
    Thank you very much for all your help but here I'm realy, realy getting fed up with this. Either it should work perfectly, either not, but here, sometimes it works, sometimes not, and there's no appearant reason when it drops.....you'll never know when it's gonna happen and for how long.
    So disapointed!

  • Extreme slow down when using wireless connection

    I did not have a wireless network prior to purchasing the airport express and needed this as I purchased a macbook. My intention was only to use this device as a wireless network. I have my cable modem connected to a linksys router which is connected to the airport express. The internet connection on my macbook is extremely SLOW! I have reset and reinstalled my airport several times, called apple support and trouble shoot for over an hour, however still experiencing the same problems...slow internet connection. In my troubleshooting I have determined that cable modem and connection, router and airport are all working properly. So the only other thing is interference issue. I've tried changing the channels, use interference robustness option however still no results. I just want my laptop internet connection to work fast. This is my last hope otherwise I'm going out tomorrow to buy a wireless Linsys N router. Any suggestions????

    Well it turned out to be a DNS configuration problem on the MacBook. If you go to Networks-Advanced in the System Preferences for the Airport connection, then select the DNS TAB. In there I had a spurious DNS entry. I deleted the one that was manually entered in (it's in black text) that way the one I received from the Airport Express was the only one in there (it is greyed out and you can't delete it.)
    Hope that helps.
