Complicated (to me) Airport network question

Greetings:
I am running an Airport network with the following devices -
2 Airport Extremes in a WDS network
4 Airport Express(s) - 1 as a printer interface, 3 as Airtunes devices
Various ethernet devices connected to the base station routers
All working perfectly - then I get this problem.
Two days ago I added a Panasonic BL-C131A wireless Network Camera to the system.
It requires a port assignment and a static IP address.
Got it up and running perfectly. Ran for multiple hours without a problem.
Suddenly problems - became erratic, then unresponsive.
After a day of diagnosing the problem, I have discovered this:
If I restart the camera, it will connect wirelessly to the Airport and work perfectly until any other client joins the network. Then the problem occurs.
If I connect the camera to the Airport via ethernet cable, I do not get this problem. It only occurs when operating in the wireless mode.
I have contacted Panasonic customer support, they were helpful, but since the camera connects correctly and operates correctly when using ethernet access to the Airport, and the problem occurs only when using the wireless side of the Airport, they though it might be a problem or setting on the Airport system.
Any help, guidance, or advice you can give would be greatly appreciated.
Thanks

This cannot be the final answer the Panasonic BL-C131A camera was working fine with a cheap wireless router that I had before the Airport Extreme. I cannot even get it to talk to AE router.
My Fujitsu tablet is also having problems cannot connect either.
My two Dell notebooks connect okay but they are slow.
Anybody else have any luck with the BL-C131A camera?
Thanks,

    I have a Airport network at home with a Time capsule connected via ethernet cable to modem. Also the network is extended wirelessley with an Airport Extreme. I now wish to add a second Airport extreme but am considering a hard wire connection with 100 ft of cat 6 cable from the Time capsule to the second Airport extreme.  Can my network operate properly to extend the network with both a wireless and wired extend functionallity?

    I now wish to add a second Airport extreme but am considering a hard wire connection with 100 ft of cat 6 cable from the Time capsule to the second Airport extreme.
    Excellent plan.
    Can my network operate properly to extend the network with both a wireless and wired extend functionallity?
    Yes, but don't get confused about the second AirPort Extreme, as it would not be configured to "extend" a wireless network.....it would be configured to "create a wireless network" using the same wireless network name, security settings and password as the Time Capsule network. Configure the second Extreme in Bridge Mode.
    This Apple support document will show you how to hookup and configure the second AirPort Extreme:

  • Connecting two printers wirelessly to Airport network?

    Hi,
    I currently have a working wireless network with the Linksys Wireless-B Broadband Router BEFW11S4 - which I believe is 802.11b - that connects 2-4 laptops at any point in time.
    I just purchased the new Airport Extreme 54 mbp Base Station. I would like to
    1. Set up the Airport network.
    2. Put our two printers on the network and print wirelessly.
    The printers are on are far away (1st floor) from the cable internet access point (2nd floor) so USB connection is not an option.
    I have two questions:
    1. Would it be better/simpler to purchase a print server to connect to my Airport network and make the two printers available for wireless printing?
    2. Is it possible to connect ("bridge") the two wireless routers and then place one router close to the printers and connect via USB. If yes, should the configuration be Airport to Linksys or Linksys to Airport?
    If there are any more simple/smart solutions than the options I came up with - they will be much appreciated. Thanks for reading this long question!

    Complex question that I don't think I can answer all of...
    Airport Extreme Base Station - can connect only one USB printer - no hub permitted.
    Print Servers (other than Extreme/Express) - work great for postscript printers, but are problematic with non-postscript printers. Printing to print servers uses "standard" protocols. In OS X, the "standard" protocols are provided by CUPS, so they need cups-capable drivers on OS X. Brother is the Only non-postscript printer manufacturer so far to provide CUPS drivers. Many non-postscript printers can be made to work with third-party drivers (Gimp-Print is one of these), but most people are unsatisfied with print quality (if you want to print photos for example).
    I think wireless bridging will work with the Airport BS in the "receiving side" only -- but I haven't tried that.
    For more help on the printers/network printing, need to know the printer models.
    Hope this gets you started.

  • Airport Network - Card vs Base Station?

    G'day,
    I have been considering setting up an airport network in my home for some time. The devices I'd want to network are:
    eMac
    G3 Powerbook (with airport card already)
    USB Canon Pixma printer
    Motorola Cable Modem (ethernet connection)
    From what I gather, the easiest option is an Airport Extreme base station, HOWEVER I've just been using my Pismo (G3 laptop) to allow my Nintendo Wii to go online. That made me wonder - why couldn't I simply get an airport card for my eMac (which usually has the modem hooked up to it), and then do like what I did for the Wii - share the connection via its card.
    Given that my Pismo could talk to the Wii from one end of my house to the other, I assume the eMac should be able to do likewise...
    Is there any serious problems with this option Vs using an actual Airport "base"?
    Thanks
    cosmic

    o The highest level of wireless security will be WEP, which is no longer considered secure.
    You might find that not even this is possible if you want to connect the Nintendo Wii
    Another issue is that the eMac would need to be directly connected to the internet, whereas if you had a wireless router you would at least have the benefit of the router using NAT and therefore hardware firewall protection.
    The problem with sharing your internet is that it then becomes complicated running a software firewall.
    I would recommend getting a wireless router of some kind.

  • Designing an Airport Network

    Question 1.
    I have the document:
    "Designing Airport Networks Using Airport Utility"
    The cover says "Mac OSX V 10.5"
    I am running 10.4.11.
    Can I use that document?
    Is there another for 10.4.11?
    Question 2.
    The directions that come with the Airport Extreme say that you need to use the Airport Utility that comes in the package (I have a new extreme due today); other utilities will not work. I have a copy of an airport utility on my computer that came with the Airport Express that is currently powering my network.
    Do I need to remove the old utility before installing the new one. Or will it overwrite it? How do I do it and not get the two conflicting when I set up the new network?
    Probably a dumb question, but I do not have any experience with removing applications from the Mac.
    John

    I am running 10.4.11.
    Can I use that document?
    Yes.
    Is there another for 10.4.11?
    Earlier documents referenced Airport Admin Utility or Airport Management Utility. They may not work with the newest Airports. You can use Apple's latest Airport Utility for all Airports including older models. You don't need to remove the old program, but if you want to get rid of Airport Admin Utility just drag it to the Trash.
    Probably a dumb question, but I do not have any experience with removing applications from the Mac.
    You simply drag them to the Trash. No uninstallation programs are necessary. Only Windows requires you to conjure a wizard to do something as simple as erasing a program.
    OS X stores individual program preferences in ~/Library/Preferences and ~/Library/ApplicationSupport but these are usually very small and can be ignored.

  • How to extend an Airport network further than an Express' range?

    Hi,
    I'm trying to (massively) extend an Airport network, but there aren't electrical outlets close enough together on our property to string together a series of Airport Express "repeaters." Is there another product, eg. from a third party, that has a larger range?
    Thanks,
    Marv

    My policy on answering questions is that I never answer one unless I've done it myself to verify.
    In addition, you might want to refer to Apple's own Support Document linked below on extending....which anyone working at an Apple Store would have immediate access to with a few clicks at the computer:
    Unfortunately, if someone at an Apple Store told you that the Time Capsule could not be used to "extend"......he was just wrong or too lazy to look up the answer, so he made one up. You might want to show him his own support document...and then talk to another sales guy there when you need product information.
    Products Affected
    AirPort Express 802.11n (1st Generation), AirPort Extreme 802.11n (1st Generation), AirPort Extreme 802.11n (3rd Generation), Time Capsule 802.11n (1st Generation), Time Capsule 802.11n (2nd Generation), Time Capsule 802.11n (3rd Generation)

  • There was an error joining the Airport network with WEP or WPA

    I use a wireless adsl modem router (Philips). I can only connect via wireless to this router without encryption.
    As soon as I use WEP or WPA encryption, I get the error message "There was an error joining the Airport network".
    Thank you for any suggestion.

    Here are some articles that may help you:

    Do not overlook the possibility that the router itself may be incompatible or may require a firmware update to work properly. You should configure the router to use WPA2, preferably, as this is the most compatible form of encryption with Airports.

  • Fun Extending an AirPort Network

    I previously had an AirPort network configured as follows:
    AirPort Extreme(n) Base Station connected to Internet router via Ethernet
    Time Capsule and AirPort Express extending the wireless network
    The good idea fairy hit me and I decided to do some home cabling. The end result was that the Time Capsule is now also connected to the Internet router via Ethernet. This is where the fun begins.
    I'm not sure what to do from here, but here is what I have done so far:
    1. AirPort Extreme on wireless channel 1, with the box checked to allow the network to be extended
    2. Express still extending the wireless network
    3. TC set to "Create a Wireless Network" using the same wireless network name and WPA password as the Extreme, but on channel 4, also with the box checked to allow the network to be extended.
    Questions:
    1. What, if anything, have I done flat-out wrong, and what could I do better?
    2. Specifically, should the Extreme and TC be on different channels?
    3. Does it hurt that they both have the box checked to allow the wireless network to be extended?
    4. Anything I have missed?
    Thanks in advance. It appears that my cabling skills exceed my network admin knowledge.

    So in your new configuration, I understand the following: Modem > AEBSn > TC >>> AXn, where ">" represents an Ethernet connection, and ">>>" would be a wireless one. Is this correct?
    If so, the following would be the basic settings for each of the routers:
    AEBSn
    o Wireless Mode = Create a wireless network
    o Allow this network to be extended (disabled)
    o Wireless Network Name = <enter desired Network Name here>
    o Radio Channel Selection = 1
    o Connection Sharing = Share a public IP address
    TC
    o Wireless Mode = Create a wireless network
    o Allow this network to be extended (enabled)
    o Wireless Network Name = <same as AEBSn>
    o Radio Channel Selection = 6 or 11
    o Connection Sharing = Off (Bridge Mode)
    AXn
    o Wireless Mode = Extend a wireless network
    o Allow wireless clients (enabled)
    o Wireless Network Name = <same as AEBSn>
    o Radio Channel Selection = N/A
    o Connection Sharing = N/A

  • Advice on set up for a mixed Airport network with guest network.

    Hi,
    The manuals on the Airport Extreme and Airport Networking are more technical than my knowledge base can follow.  I would like advice on how to set up a new network with a mixture of wired and wireless devices and some Windows equipment as well as os x based macs.  the following:  dsl broadband from Talk Talk to be managed by a Draytek Vigor 120 external modem connected to an Airport Extreme.  I want to connect a Nov 2009 iMac (with Mountain Lion installed), Apple TV and xbox by ethernet cable to the 3 ethernet ports on the Extreme, but also to connect wirelessly one Windows 7 laptop, one Macbook Pro (2010) (again running Mountain Lion) and various other wireless devices like an iPad 2, iPhones etcetera, with all devices being part of one network run under one SSID and able to access the internet, and the 3 computers being able to fileshare with each other. On my current Windows created network which I am abandoning for reasons I won't go into here, if more than one of the computers is switched on, I can use any one of the computers to access information in any of the shared folders on the other computers - via Finder in the case of the macs - and I need this going forward.  I would also like to create a Guest network as I have a lot of people come to stay who need internet access. To further complicate things, I would also like to add in an Airport Express wirelessly onto the network and link that to a hi-fi to give me the ability to play my iTunes library (situated on my iMac at present) on the hi-fi. 
    I appreciate that there are similar questions but I have not really found an answer that exactly nails my situation.
    Thanks in advance.   

    It is not really an issue of how many clients can the iMac serve, but more about the volume of traffic you are processing or data the database application needs to serve. We have a Mac hardware that is a good 6 years or more old running OSX Server and supporting 20/30 clients without any problems.
    One idea you may like to consider.
    Don't run the VPN on the mac, get a router or separate dedicated networking box that provides that purpose. Then it will talk the load of any networking issues and external attacks. It can also provide other networking services for you such a DHCP, firewall, DNS, internet gateway, etc. They cost less next to nothing and are easy to install.
    When you need to get something faster, look for a second hand xerve - we use them all the time. They have the advantage of have fast and very reliable discs, also you can raid the disks and hot swap them for backup purposes,
    Finally, moving from one machine to another is each with things like carbon copy. But you cannot have the same licence for OSX server running twice, so you will need to install normal OSX on the iMac once you have done the move.
    As for can you easily move from a imac to mac pro, sure not to hard to do.

  • WEP setup with Airport network

    Greetings,
    Hopefully this will not be a difficult question. I have an Apple Airport network that I have been using to connect a Playstation 2 to the internet with using a WGA11b Game Adapter. Being in a rural area I had not worried about using any security on the network.
    But now that situation has changed causing me to activate WEP security on the network. I am unable to figure out how to modify the settings in the Game Adapter to recognize the new security. Is there a way I can "talk" to the Adapter with one of my Macs to fix this?
    Matt Bowerman

    You will require a windows based PC as the setup disk that comes with the GA will only run on windows...and that';s the only method to configure teh WGA11b since it does not have a web interface.

  • Time Capsule Network question,

    Hi there,
    I just wanted to try and get a better overview of what's happening with my TC.
    I have a 2010 bought TC,
    I live in a relatively small apartment so range and signal is not an issue,
    When I first got it I set it up as automatic G and N compatibility, I thought that meant all N clients went on 5GHZ and everything else went 2.4GHZ,
    What I realised then was that what was actually happening was that ALL clients were jumping on the 2.4GHZ network with the N clients connecting at about 144Mbps and the G clients at 54Mbps, I was really suprised at this behaviour and even MORE suprised to find out that if I manually ran a 5GHZ wide band network simultaneously with a slightly different SSID ie (Airport 2.4ghz, Airport 5ghz) that N clients would connect at 300Mbps on the 5GHZ network and G at 54Mpbs on the 2.4GHZ network, I can't find anywhere this is explained! and all of the websites that tell you how to set up time capsule never mention that you will get twice the performane with a seperate 5ghz band running. I can't see the downside to this and think it should be default behaviour? All clients can still communicate with each other regardless of which band they connect to.
    I then tried to set up the guest network just out of interest and could see that my TC was now broadcasting 3 SSIDS! One for the 2.4ghz one for the 5ghz and one for the guest network.
    So what frequency is this guest network broadcast in this configuration? Also is it possible to broadcast 4 SSIDS? One each for 2.4 and 5 ghz on the standard network and a 2.4 and 5 on the guest??
    Also what are you thoughts regarding my original point of having to set up the 5ghz manually to get clients to connect at over 144Mbps?
    Thanks,
    Regards,
    John

    I can't see the downside to this and think it should be default behaviour?
    Remember that Apple always tends to try to make things simple. It's much easier to tell a typical user that his computer will connect to the best available signal and leave it at that. Probably 90% of users don't even understand what dual band is.
    You have a small apartment so signal strength is not an issue. But, it's a fact that 5 GHz signals are not nearly as strong as 2.4 GHz signals. After all, you can't get something for nothing. In the case of 5 GHz, you gain speed, but give up distance capability and penetration power.
    In a larger home, if the default were to have a separate name for the 5 GHz network, a lot of users would not be able to connect using 5 GHz if the signal has to pass through multiple walls or a ceiling and a few walls. Even if they might get the 5 GHz signal, it will be much weaker. They will have a better, stronger and more reliable connection at 2.4 GHz in this case. Isn't that what they want?
    The default setting of the AirPort is to let computers connect to the "best" available signal quality. True, the "best" quality signal may not be the "fastest" signal in some cases. Still, for most users, having one network name for both bands makes a lot of sense.
    Users who are interested in advanced features and setup have an excellent resource in the Apple AirPort Networks Guide. It's right there on the main forum page for all to see. Did you not see this?
    So what frequency is this guest network broadcast in this configuration?
    The Guest network is dual band as well. You can't assign a separate name to the 5 GHz band on the Guest network. Both the 2.4 GHz and 5 GHz bands use the same network name or SSID.
    Also is it possible to broadcast 4 SSIDS?
    No, 3 would be the maximum.
    Also what are you thoughts regarding my original point of having to set up the 5ghz manually to get clients to connect at over 144Mbps?
    As a regular member of the forum assisting dozens of users each week, I've stated my opinion above. I dislike trying to generalize, but Apple made the right decision for most users with the present default settings. As I said, we spend a good deal of time just trying to explain what +dual band+ is.
    You appear to be an advanced user interested in advanced features and settings on the router. That's good. We could use some more help on the forums, so please check the forum pages often and help us out when you see a question from a user asking about the more advanced features of the router.

  • Share files in ibook - networking question

    Hello, I have a networking question.
    I have a brand spakin' new 13' MacBook Pro and an older 14' iBook G4 (with a broken airport wireless card).
    My internet is set up so that I have the modem connected to a "wired" ethernet hub, then to an airport express. This way I have wireless for my new MacBook Pro, and I can connect my old iBook to the internet with a ethernet cable.
    Herein lies my question: I want to access all my files on my ibook from my MacBook Pro. I've tried the file sharing and etc on system preferences, but for some reason it still doesn't work. I believe its because they are on different networks? (one wireless, one wired?)
    Any ideas to make my ibook a simple file server.

    Try repairing disk permissions.
    *"The external HD has two partitions, one is a backup of the ibook, and the other has mixed media. When I access my ibook over the network, Only the backup partition appears, and not the mixed media partition. "* Try repairing permissions but not sure if that's going to work. Can't hurt to try.
    Launch Disk Utility. Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac.
    Also, your profile indicates you are running 10.4.3. If that is the case, you might want to run Software Updates (from the Apple Menu , then click Software Updates.

  • Linspire & encryption on my Airport network

    Normally I run 40 bit encryption on my Airport network, along with the Access Control to only include those MAC addresses I want to join the network. I have 2 iBooks, a desktop G4, a Win98, and a WinXP computer on my network. For the two windows machines, the network password is different, of course, than it is for the Macs. Now, my question is, though .......how about for Linspire? Which encryption/network password is used for it? The Mac one or the Windows one? Or something different? Also, what is 40 bit encryption equal to on Windows? Isn't it different?
    Thanks for any help!

    40 bit WEP is sometimes (though not always) referred to as 64-bit WEP.
    See this article, which explains some of the issues behind why one WEP password sometimes needs to be expressed in different ways on different manufacturer's wireless networking hardware. Since there is no common way for Linspire either, you just have to experiment until you find a format that works.

  • Applescript to select specific airport network

    hi all,
    I'd like to write an applescript to select a specific airport network named 'NETGEAR'
    I haven't got much experience with Applescript and I can't get Automator's 'Watch Me Do' to work properly.
    What i'd like done is:
    -select the airport menu (in the menu bar)
    -select the wifi network 'NETGEAR'
    using automator and applescript editor, I've got the following scritpt:
    on run {input, parameters}
        -- Click the “AirPort Menu Extra” menu bar item.
        delay 1.664016
        set timeoutSeconds to 2.0
        set uiScript to "click menu bar item 6 of menu bar 1 of application process \"SystemUIServer\""
        my doWithTimeout(uiScript, timeoutSeconds)
        return input
        -- NETGEAR
        delay 0.882737
        set timeoutSeconds to 2.0
        set uiScript to "click menu item \"NETGEAR\" of menu 1 of menu bar item 6 of menu bar 1 of application process \"SystemUIServer\""
        my doWithTimeout(uiScript, timeoutSeconds)
        return input
    end run
    however, this returns the dialogue: 'AppleScript Error (null)'. So clearly something isn't right.
    I'm sure that whatever mistakes I'm making are pretty obvious to someone who's more familiar with scripting.

    I am so sorry to bother you again. I have another question about how to create a script to change Safari downloaded folder.                                                                            Automatically changing Safari's downloads folder
