Airport Express Flooding Network w MDNS

I have a new (802.11n) Airport Express and an older 802.11b/g Airport Express. Both are setup in bridge mode, both connected via Ethernet to my local network. Both are setup in WDS Main mode, with the other listed as a WDS Remote. Neither one reports any problems, however the new 802.11n Airport (fw ver 7.3.2) is flooding my network with about 500 packets/sec of MDNS multicasts, mostly all Cache Flush commands. This only happens when the ethernet cable is plugged into that Airport. It slowed my entire network down enough that I noticed it right away. Is there something wrong with my configuration that is causing this or is this a problem with the n Airport? If it is my configuration, how should I configure both Airports to effectively provide a single wireless network to my clients where each access point (Airport) has an ethernet backhaul?

Hi,
I have a similar problem.
I'm using an airport extreme (802.11n) connected to a DSL modem and an airport express 802.11n to extend my wireless network. I tried to use this airport express in a room where I don't have good wireless signal from my extreme basestation (when the door is closed I don't receive any signal anymore). So I tried to connect my airport express wired with an ethernet cable. At this point I also see that the network is slowing down with a lot of activity (lights going in and out ...) on my switch board also causing problems to other systems in my network (homeserver etc ..)
On the other hand, the light on the airport is green and there is no problem reported in the airport utility.
The trouble ends when I switch off the wireless funktion or when I plug out the ethernet cable.
(And it restarts immediately (whitin 1 sec) after I plug in the cable.
Does anyone know how to solve this problem ? Or how to have Wifi from an airport express that I use to extent a WiFi network in a room that doesn't have a good signal from the base station
Thanks a lot for your help

  • HELP ibook g3 OSX 10.2.8 no longer detects airport express wireless network

    my ibook G3 OSX 10.2.8, airport admin utility software 3.1.1 no longer can detect the airport express wireless network (powerbook G4, OSX 10.4.11, airport admin utility 4.2; airport express, WEP protected, to DSL modem). i just installed an ipod driver update on the ibook, and wireless networking went down on restart. any help greatly appreciated!

    you name it : com.apple.airport.adminutility.plist
    delete it and do as advised.
    This isn't harmful, because it is only a preference list, so it will be created brandnew as soon as you re-setup the Airport stuff.
    Mac OS X ( especially Jaguar ) has a tendency to corrupt some plists out of the blue, it is more or less harmless and can be fixed with recreating them plus permissions-repair.
    Hint : repair permissions more than one time, it ALWAYS finds something to fix in Jaguar.
    You cannot destroy something with these actions, because it is Unix maintance so usual routines.
    A tool like cocktail or Onyx ( google them, onyx is freeware ) can help you run such ( and more ) routines on a scheduled base.
    Always remember that OS X is no longer "the Mac OS", it is Unix with a nice Desktop, the critical things run hidden in the background, so it has to be treated like any Unix/Linux sort of OS, even if from the outside everything looks nice and kosher..

  • PCs suddenly no longer see Airport Express wireless network - please help!

    Hi,
    I am new to this forum and I need help. Two days ago - without me making any changes to settings etc. my Airport Express wireless network at home was no longer visible to any of my devices except to the Powerbook (G4 OS 10.3.9) which controls it. From one second to the next two Vista laptops and my cell phone (Nokia, Symbian OS).
    My Powerbook has no problem connecting through AE to the internet. The two laptops are both able to connect to other wireless networks so they don't seem to be the problem. I just don't understand what caused this sudden drop-off/invisibility.
    I have already tried the following: resetting the base station, changing the channel on the base station (from automatic) removing the network security altogether (from WPA2). But none of the devices except the powerbook can now see or detect my network.
    Please - if anyone knows what the cause of this problem could be or how to fix I would be very grateful!!

  • Airport Express WiFi network MAC address filtering not working

    I have an Airport Express WiFi network which I bought and installed new in 2011. Initially I enabled MAC address access control and populated a list. It was working perfectly, I know, because a niece visiting tried to connect her iPhone and could not until  I added its MAC address to the allowed list. Now however, anyone can connect without being added to the list. I think I read somewhere that a recent firmware update permanently disabled MAC filtering in Airport Express, even when it was previously working? Can anyone enlighten me about what's going on here?

    In a sense those are/were/should operate as two separate functions, which they did before recently.
    They do operate as two separate functions.....but it all depends on how you have the default rule setup in Timed Access.
    If the default rule in Timed Access is set to No Access.......then a wireless device cannot connect....even it has the password for the network.....unless it has been setup on the list of allowed devices in Timed Access.
    I have checked this 3 times this evening to verify. It works as it always has, and as expected.
    If the default rule in Timed Access is set to Unlimited, then any device can connect to the network if it has the password. Devices that are listed or specified in Timed Access will be allowed to connect at the specific times that have been set up for each device.
    So, if you want to use the more traditional MAC Access Control settings, the default rule has to be set to No Access and then you must set up a rule for each device that you want to allow to connect to the network. Only devices on the Timed Access list will be allowed to connect to the network. Other devices will not be able to connect to the network....even if they have the correct password.
    If a recent firmware update has changed things from what they have always been.....then I am not affected....and I should be if I am using the same firmware as others.

  • Iphone will not connect to airport express extended network - macbook and ipad will - Help

    Iphone will not connect to airport express extended network - macbook and ipad will without problems.
    iphone will connect to base station no problems, I've restored settings and started again but still the same, the iphone picked up the network for the last couple of months, but not now ?

    I'm having the same issue. My AExpress used to give a good signal strength on the far side of the house extending he network created by my Extreme. However, I've noticed lately that my iPhone does not receive the same strong signal it once did. AE has a green light, I've rebooted it, and my Extreme but there is no change in signal strength. Other than the green light, how can I tell if the Express is working if I don't get a good network signal?

  • Linking Dell Laptop to existing/working Airport Express wireless network

    Hi,
    I'm trying to connect a Dell Laptop (Inspiron 2500) running on Windows XP to an existing and functionning Airport Express wireless network set up for my girlfriend's iBook. It works perfectly for the iBook.
    I have outfitted the Dell with a D-Link wireless G USB adapter and I see the network (i have the password) and it says I am connected to the network (even says connection is very good).
    However, when I open the internet browser, nothing.
    The network set up is: Cable to RCA Digital modem (model DCM425) to Airport Express (via ethernet) and to computer.
    I have tried playing around with the Dell Laptop settings (IP, DSN, etc ...) and I have called everyone involved (including Apple) to no avail.
    Any help would be greatly appreciated!
    Thanks,
    Nick
    Dell Laptop   Windows XP   iBook

    Thanks for the reply.
    WEP is enabled. As far as the encryption, I'm not sure. I believe that it's 64-bit, as the password for the network is a five-letter word.
    The funny thing, though, is that I had been using an IP address which I found on my girlfriend's Ibook, which allowed me to connect to her AEBS network, although the internet browser showed no connection.
    Following directions from somebody else, I removed the IP address to enable DHCP, and then I was able to connect to other networks in the area (and the browser also connected to the internet) but I couldn't get onto her network anymore. Even with the password ...
    Any ideas?
    If i'm supposed to upgrade to 128-bit, how should I go about doing that?
    Thanks again for the reply.
    What encryption are you using?
    Do you have WEP enabled?
    The problem you are having probably lies with the
    encryption key.

  • I use Airport Express to network 3 iMacs to a DSL modem.  Recently, the network became undiscoverable to one of the iMacs.  Suggestions for a fix?

    I use Airport Express to network 3 iMacs to a DSL modem.  The network has become undiscoverable to one of the computers. I have reset the base station to factory settings but this does not help.  The other two computers are unaffected. All 3 computers can access the internet when connected directly to the modem.  I suspect the problem might be the Airport card?  Suggestions?
    beaucleo

    Thx for the suggestion, although I didn't have to reset the SMC to fix the problem. The problem was the handshake between the security password and the designated network.  The following links gave me info for investigationg the problem.

    I would recommend these web sites to anyone who is having problems setting up and/or maintaining a wifi system.
    I discovered after reading one of the web references that if I disabled nework security the problem went away. This, however, was unacceptable.  Further experimentation showed that the solution to my problem was to change the name of my network while keeping the same password.  I tried only changing my password but that didn't help.  I still don't understand why only 1 of the 3 networked iMacs was affected.
    Again, thx for your interest and reply.

  • DHCP issues connecting a Macbook to an Airport Express/Extreme network

    My fiancée's macbook sometimes won't connect to our network, while my MBP has no such problem. A wireless connection is successfully established, but it doesn't get an IP address assigned. I've tried turning on/off Aiport, renewing the DHCP release, but to no avail. It continues to have a self-assigned IP address.
    Currently, a reboot (much to her annoyance) is the only known solution.
    My network consists of an Airport Extreme base station (v5.7) and an Airport Express enabled as a WDS remote base station.
    Any tips into how to better diagnose this problem will be much appreciated.
    At the very least, is there a way to restart (SIGHUP?) the Airport daemon as if it were going through a reboot?
    Thanks

  • Time Capsule & Airport Express Extended Network loses connection!

    OK, so I am an Apple virgin of 2 months experience, after many many years with Windows based PCs, so please be patient and gentle with me. Sorry about the long explanation.....
    My set-up comprises of a Time Capsule, which is connected to the Internet via a NetGear ASDL modem. Both pieces of equipment are situated in my wife's office on the first floor of our house. My office is on the ground floor, where I have a 27" iMac and an Airport Express which is connected to a printer via the USB port. The Airport Express is sited about 10 feet from the iMac.
    All software and firmware are lastest versions - TC v7.5, AX v7.4.2 & Airport Utility v5.5.
    For the past 2 months, I have only been using the AX to print wirelessly and the set-up has worked faultlessly.
    Earlier this week, I decided change the configuration to extend the network to allow me to use my laptop & iPhone in areas of the ground floor where I had no signal. I followed the online instructions and first changed the TC to check the box to 'allow this network to be extended', after updating the configuration successfully I moved to the AX. Here I changed the wireless mode to 'Extend a wireless network', selected the network name and checked the 'Allow wireless clients' box. This also updated successfully.
    Everything ran correctly and the range of the network was greatly increased.......great, job done...not!
    After about 3 hours the iMac lost the connection and the TC disappeared from the Airport Utility pane and refused to reappear. I checked but also couldn't connect or see any network on the laptop or iPhone, so have dismissed a fault with the iMac. I finally got things back up after doing a power reset of the TC, but after a few hours same problem occurred, and occurred and occurred. By clicking the Airport Utility icon on the top right of the screen and following the prompts from 'no Internet connection', I can at least get things up and working without a power reset of the TC, but the connection still drops after 2-5 hours each time.
    My first call to Apple Support led to a full reset and re-config of both the TC and AX, setting the extended network up as I had done originally. The only difference was an iMac reset (alt/cmd P&R on power up) and changing the 2.4Ghz channel from 1 to 11. This had no affect and the connection drop-out problem continued.
    My second call to Apple Support led to me being passed to a Level 2 Techie, who first suggested that I tried disabling the Guest Network - tried it, and it made no difference. I was then told to try a WDS network, which whilst not losing connection, is slower and has less range than the original extended network and frankly sounds a cop-out.
    Has anyone had a similar problem, anyone solved the problems, can anyone offer any help or advice please.. I'd appreciate any input....thanks.

    Similar problem here. Cable Modem (Moto SB6120)->AEBS (802.11n dual-band)>AX (802.11n) for wireless connection to MacBook Pro running Mac OS X 10.6.2. AEBS configured as dual-band: 801.11a/n at 5GHZ and 801.11b/g/n at 2.4 GHZ. AX configured to wirelessly extend the AEBS 5GHz 802.11a/n network. I am able to run on the extended 5GHz network (via AX) for varying lengths of time, until the internet connection dies. When this occurs, I am able to switch over to the 2.4GHz network to get back online. Solution up until now has been to unplug the AX, then plug it back in. After the AX restarts, I am able to hop back onto its 5GHz signal and get to the internet. However, the internet connection on this band will drop again after some time.
    I was on the phone with Apple Support twice in the past week to get this resolved, but no joy. Senior Advisor seemed to think that my AX was working properly, and that that the problem could be with my AEBS -- perhaps the 5GHz antenna might be bad in my AEBS? Seems odd to me, since both my AEBS and AX are less than 2 months old...
    I just read the post from LocoDoc and decided to see if I could replicate the problem. Sure enough, when I am connected to the internet via my AX extended 5GHz network signal and a Time Machine backup starts, the internet connection quits. Only recourse is to restart the AX. Note that I do not experience this problem with Time Machine while connected wirelessly straight to the AEBS 5GHz signal. Only when I am connected to the "extended" signal via the AX.

  • Airport Express wireless network works fine, but won't connect to Internet

    I had a power outage and since then my Airport Express doesn't connect to the Internet although everything else seems to work. I can see the AE just fine in the Airport Utility. My computer connects to the wireless network provided via the AE, so does my iPhone, so does my wireless printer, and I can print wirelessly from the computer to the printer, so the AE's wireless networking is working. If I directly connect my computer to the ethernet connection that I use for the AE, it connects to the Internet, so I have wired connectivity to the Internet. But somehow, I can't get to the Internet using the wireless network of the AE. Any suggestions on what I should try next?

    Hi there,
    Try to reset your Airport Express (AX), y pressing the little dot on the back of device. Keep pressed for some seconds until it flashes. Start then your Airport Utility and go through the setup process again. This will reset your whole wireless network. This may work for you. Good luck.

  • I'd like to alter my Airport Extreme/Airport Express wireless network so that the 3 Expresses connect to the Extreme via Ethernet. I've been told this will create a more stable wifi signal. How do I configure this using Airport Utility? Thanks.

    I currently have an Airport Extreme Base Station connected to my DSL router by Ethernet. Because I have a long, sprawling home, I have 3 Airport Expresses configured to "Extend the Wireless Network" I've established. Because of my home environment--thick walls encompassaing wire mesh, sprawling rooms, etc., it is hard to maintain a continuously-strong, stable WiFi signal. I've been told that I can create a much more stable network by connecting the Express units to the AEBS via Ethernet cable. Since my home is already wired for Ethernet, I'm considering making this change. If I proceed to establish the Ethernet connections, how do I then set up Airport Utility to accomodate this switch from a Wireless-based WiFi network to an Ethernet-based WiFi network?
    Thanks in advance for any help.
    Phyllis

    I don't see anyplace in the Utility to designate HOW the Express units are connected, only how they relate on the network to the Extreme,
    As I mentioned in the previous post, when you click the Internet icon in AirPort Utility:
    Connect Using = Ethernet  (This tells each Express to connect to the Extreme using the ethernet connection)
    Connection Sharing = Off (Bridge Mode)  (This setting allows your AirPort Extreme to function as the "main" router on the network, as it must for the setup to work correctly.
    You do not need to configure anything differently on the AirPort Extreme (as long as it is working correctly now) to connect the AirPort Express devices.
    The only other question I have is the following: I'm currently already using one of the Ethernet ports on the back of the Extreme-- for my husband's iMac. I really don't think he gains much in performance over how the iMac would run through wifi, so I could disconnect the iMac. If you think the iMac would do better to stay on the Ethernet connection, should I use a switch/splitter to add an extra connection?
    Since each AirPort Express must connect using ethernet, you will need to use the 3 LAN <-> ports on the AirPort Extreme for the AirPort Express devices.
    I would suggest that you try connecting the iMac using wireless to see if that will work. If the wireless connection is not satisfactory, then you can add a 5 port ethernet switch to one of the LAN ports on the Extreme and then plug all the devices connecting using ethernet....the iMac and the 3 AirPort Express devices...into the remaining 4 ports on the switch. That will leave you with 2 open ports on the AirPort Extreme for any future devices that may need to connect.
    When you test out the system, here is a trick to find out which device your computer is actually connecting to at any given time as it "roams" around the house.
    When you have AirPort Utility open to configure each AirPort Express, jot down the AirPort ID for each Express. You can do the same for the AirPort Extreme.
    As you move around with your laptop, hold down the option key on your Mac keyboard while you click on the fan shaped AirPort icon at the top of the screen. Look for the BSSID. That is the AirPort ID of the device that the laptop is connected to at that time. it should also be the ID of the closest AirPort Express (or AirPort Extreme if the laptop is close to the Extreme at the time).
    Let us know how things are working when everything is up and running.

  • What are the downsides to extending an Airport Express's network with Airport Extreme?

    Or are there downsides at all, assuming latest generation Airports? I think it happens more often than not that the position of the modem from your ISP in the dwelling is not the ideal location for a router, and it is sometimes inconvenient/impossible to wire an ethernet connection to the optimal location. I have an Airport Extreme and an Airport Express, and was thinking of hooking up the Express to the modem and having the Extreme extend that network, placed at the optimal router location. My concern with that setup is whether the Extreme will use all of its antennas, since the Express has fewer (6 vs 2 if I'm correct).

    Or are there downsides at all, assuming latest generation Airports?
    There are none. You might be confusing such a "wirelessly extended" network with a WDS, which was a horrible compromise with significant disadvantages.
    The optimal location for the second AirPort might not be obvious. Keep in mind that it can only "wirelessly extend" the signal it is capable of receiving. Place it in a location where the wireless signal created by the main router remains strong, while still being able to create a network that covers your required wireless service area.
    Don't worry about the number of antennas or how they are used. They're all used.

  • Xbox 360 does not connect to Airport Express wireless network

    I'm at my wits ends. I got a my son a wireless adapter for Christmas and for the life of me cannot get it to work. We have looked at all the discussion forums on the internet and did A LOT of trial and error and still to connection. On one occasion the xbox 360 wireless adapter saw the network and once it tried to connect is dropped.
    I have a Wii, two windows PC's, a printer and a PowerMac all connected to my wireless router. The xbox and the Airport Express both have the latest firm ware update.
    These are some of the things I have noticed and tested:
    1. Connection is Cable Modem>Vonage Router>Airport Express....wireless to Xbox360
    2. I have taken the vonage router out to go
    Cable Modem>Airport Express...wireless to Xbox360 and still no luck.
    3. I was suspecting a double NAT and contacted Comcast to see if I could put the cable modem in bridge mode and they couldn't help me.
    4. The network is open (no security)
    5. The wireless adapter is a steady red...then when I tell it to find the network it drops out (LED turns off)
    6. I have tried to see if I have a double NAT but tracing in the network utility does not show anything.
    7. I have tried to place the Airport express in bridge mode and when I updated, it doesn't not come back up and I have to do a hard reset to communicate to it again.
    8. There was one instance when the wireless adapter LED was green for about 15 secs and when we tried to connect it dropped out completely (no LED light).
    9. I know it works because in the various forums I have read that people have it working.
    I called xbox support and they were not very helpful...wouldn't even search similar cases...I have tried everything I could think of and I'm lost any assistance is appreciated.
    Victor

    Tesserax,
    What is the make/model of the Comcast-provided modem? How about the Vonage router? Is this router also wireless? Finally, I assume that prior to introducing the AirPort Express Base Station (AX), the modem & Vonage router were working properly ... correct?
    Thanks for your interest in helping me. To answer your questions:
    1. The comcast make and model for the cable modem is Scientific American Model#DPX2203
    2. The vonage router is ethernet hard wired connected between the cable modem and the apple express wireless route. The vonage router is model#VDV21-VD
    3. With the exception of the wireless connection between the Xbox 360 and AX; everything works fine.
    4. The AX is running Apple firm ware 6.3
    In the discussion I have read of similar problems and have tried them all to no avail. I'm sure the is a fix to this problem because of people in the discussion groups have had the same issues. I don't suspect the wireless router because it has a steady red light and only turns off when we do the network test or scan for networks.

  • Airport Express and network printer

    I purchased a new Airport Express with 802.11n and I can configure it properly with no issues with basic functionality. Connecting my HP Photosmart printer via USB cable also works fine. However, connecting it via ethernet connection is problematic.
    The Airport Express does not assign an IP address to the printer. I've validated that the printer is functional by hooking it up directly to my network router and making sure that it gets an IP address from it. That worked fine. However, from the Airport Express I get no IP.
    Can someone provide some clarity on how to get the Airport Express to assign my printer an IP address? Or am I barking up the wrong tree and I should just settle for the USB connection?

    I can't answer your question, but if you watch my post about ethernet networking you may get some helpful advice. My issue is that I can stream music, and use my usb printer fine, but I can't connect my iMac via Ethernet to the Express. Similar problem to you.
    I have tried connecting directly using the default Airport address of 10.0.1.1 and variations thereof and nothing works.
    And the amber light is still flashing... is yours? perhaps this is significant.
    Also, even though I can't print, my printer doesn't show up in the printers list in the Airport Admin Utility. So it definitely sounds as though there is something fishy going on with the Express not seeing things that are attached to it, or something like that.

  • Airport Express Guest Network

    This could be an Apple Airport hardware issue but wanted to double check I haven't made a mistake in setup or if anyone else has experienced this fault. We have Sky Broadband Unlimited installed running through a Sky Hub with Apple Airport Running an additional Wireless network, primarily for the 'Guest Network' feature. When enabling the guest network, we are able to broadcast the signal however the device trying to connect is unable to complete connection. I'm half confident that it could be an issue relating to the Airport requiring two IP addresses. One for the standard 'full access' signal and the other for an 'Internet Only Access' Guest Network, however it is only given one IP via DHCP on Sky Hub. My immediate thought is to set the Airport to allocate IP Addresses as opposed to the Sky Hub. Any thoughts anyone?

    I was able to get the guest facility of the AirPort Extreme to work by double NATing, but it leads to all sorts of other issues with complex environments. If yours s a simple LAN/wifi environment then switch the Airport Express to route instead of bridging and leave the Sky Hub with the same default settings. But if you have ports forwarded or games consoles this isn't recommended. I noticed you put a like on my other post concerning switching on the wifi on the Sky router with wifi isolation enabled and using that for your guests; this is also a good solution to the issue.
