I have one of the older style white Dome AEBS, which has sometimes performed flawlessly, but when it wants to act up, it's a right pain in the unmentionables...  requiring frequent (ie 1/2 hourly) resetting, etc etc.


What I'm finding at the moment is that despite my internet connectiong showing to only have a 12 ms lag, I am experiencing massive problems with DNS...


By which I mean... I will click on a link in my web browser (Firefox) and it will either just sit there doing nothing (despite other web pages actively downloading information) or lag for 5-60 seconds...


Sometimes re-clicking the link will suddenly make it go straight away...


Sometimes opening another window, and sending it to (anywhere) will make the first window suddenly work...


I'm blaming the AEBS... maybe that's wrong... but it's certainly been having issues over the past 2 weeks or so...


I have recently (few months) changed ISP... I have updated my DNS info accordingly... but guess it's also possible it is their fault...


Any suggestions?

    If any of the following symptoms sound familiar:


    • A decrease in wireless range between devices.
    • A decrease in data throughput over a Wi-Fi network.
    • Intermittent or complete loss of connection.


    You are likely picking up Wireless Interference on your network. You might want to take a look at Apple's support document for this here....which offers some suggestions to help combat this very common issue due to the rapid growth of wireless networks.




    To give you just an example of the type of issues that a cordless phone can create......my neighbor, who lives across the street....could literally bring my wireless network to a crawl if he was out in his front yard talking on his cordless phone. 


    If he came out to the street to get his mail...this sometimes would cause my wireless to crash. Luckily, he moved.

    G'day Bob,


    • Microwave ovens --- We do own one, and it is only about 2m from where the MBP is most commonly used... (and thus having issues) but the issues are happening when the Microwave is not being used... so will rule that out.


    • Direct Satellite Service (DSS) RF leakage - Umm, no satallite dishes here... though there is about 5m of tv antenna cable running across the loungeroom, in 1m lengths...


    • Electrical railroad tracks, and power stations - Did live across the road from an electric railway, but not now... Wife wont let us be near a power sub station or high tension power lines...


    • 2.4 GHz or 5 GHz phones - We did have a cordless phone plugged in/powered on... but not physically in use... Have disconnected it, and will see... though one of its selling points was being Wifi friendly.


    • Video senders (transmitters/receivers) - No


    • Wireless speakers - No


    • Certain external monitors and LCD displays - Have a 17" Apple Studio display connected to my G5, sitting next to the AEBS...


    • Any other "wireless" devices - we do have a baby monitor...

    Any Bluetooth wireless devices...keyboard or mouse can cause problems as well.


    Any other "wireless" devices - we do have a baby monitor...

    These devices are known to cause issues.


    Unless you are lucky enough to be living in a very isolated area, you are also probably picking up signals from the neighbors.  I do not not live in a crowded neighborhood, but I can "see" at least 12 other wireless networks when I take a look. This number does not include wireless security/camera systems..of which I know there are at least 3 near me...nor does it include "closed networks"...in which the user has chosen to enable an option to not have the name of the network displayed.


    If you are satisfied that your Apple router is indeed functioning correctly...and you are having the types of issues that you mention....the interference problem is coming from somewhere....the trick is to find it.


    Don't forget microwave transmission towers, amateur radio operators in the neighborhood, and probably 3-4 other things that I can't think of at the moment.


    Sometimes changing the channel on your wireless router will provide some help. Did you try that suggestion?


    Good luck in your quest to locate the cause of the problems.
