DHCP only works for wireless clients on Time Capsule. How to fix?

Hi All,
I have a question concerning the DHCP server on my Time Capsule. I'm posting here because I think you network pros lurking in this forum probably have way more insightful advice than the n00bs in the Time Capsule forum
My DHCP server on the Time Capsule only works for clients connected wirelessly to that specific access point; clients plugged directly into the network via ethernet and through other APs do not receive a DHCP assignment from the Time Capsule.
How can I get the Time Capsule to serve DHCP addresses to EVERYONE on the network, not just clients connected via the Time Capsule?
Thanks,
Chris

I don't know that TC provides that. Switch the TC over to its bridged mode (also known as an Access Point or AP), and run a DHCP Server on Mac OS X Server (fodder for this forum) or a DHCP server on another available device. Less desirable though feasible (so long as the IP address pools are coordinated and non-overlapping with other pools or static addresses), run multiple DHCP servers.

  • Bridge does not work for wireless clients - connecting to existing network.

    Hi - I really hope somebody can help out here, after hours of trial & error, I have finally given up
    I need to connect my Airport Extreme Base Station to my existing network. I have a linksys router (192.168.15.1) connected to my modem and this linksys router acts as DHCP server too.
    I suppose I have to use "bridge mode" for that to work. But should the linksys be connected to the AEBS using the AEBS's WAN or LAN port?
    If I use "bridge mode", then wired computers to the AEBS works fine - getting an IP from the linksys etc. BUT, the wireless clients will have a self-assigned IP and not get through to the internet. It's like the AEBS will not allow wireless clients to "get through" unless AEBS itself is handing out IP addresses.
    Page 36 of this manual ( http://manuals.info.apple.com/en/DesigningAirPort_Networks10.5-Windows.pdf ) shows the setup I want. But in the picture, it says "Ethernet WAN port" but the text says: "The Apple wireless device (in this example, a Time Capsule) uses your Ethernet network to communicate with the Internet through the Ethernet LAN port ( <--> )." I don't know which one to use, WAN or LAN - they show WAN but say LAN?
    When I set it up as "share an IP address", the AEBS status tells me "double nat" and to change from "shared IP" to "bridge mode". I do that, and everything seems fine - for the wired clients. Now the wireless clients cannot connect, Airport on the MacBook Pro just say "Connection failed" and the MacBook says "Invalid password" (translated from danish), even though I set the Airport Utlity to save the password in keyring, so it should be correct... If I disable wireless encryption, the wireless clients will connect but get a self-assigned IP, and therefor not work (cannot get online)...
    It seems the only way I can get wireless to work, is if I set AEBS up as DHCP, but then it won't be on the "same network" as the linksys (192.168.15.1), but rather on 10.0.x.x as I select. If I select 192.168.x.x within AEBS, I'm also getting some error messages, conflict/subnet thing.
    Anyway - I really hope somebody knows how to get wireless clients to get an IP address from existing ethernet when connected to the AEBS.
    Thanks!!

    I've given up and had to go back to running "Double NAT" which also reports as a "problem" within the AEBS, but I just "ignore" it so the light will always be green.
    It still ***** though, as "Double NAT" is also a reason for "Back to my Mac" not working properly, but how the ** am I supposed to avoid Double NAT when the wireless will not work in bridged mode?!

  • How to manually connect wireless clients on Time Capsule with Airport 6.1?

    I'm having trouble setting up wireless access for an older Dell laptop and a wireless HP 4500 printer on a new Time Capsule wireless network. All of the workarounds that I've found (adding a client manually so no WPA password is needed; generating an equivalent network password, etc) and even the Time Capsule setup manual itself reference options in AirPort Utility that are not available up on my Mac running Mountain Lion. I've figured out that the AirPort for Mountain Lion must be the root of the problem--and I can see that there are 5.6 vs. 6.0 discussions. Clearly the 6.0 version has a whole new interface and advanced options don't appear readily available. Can AirPort 5.6 run on Mountain Lion? Or is there a another way to get to these manual settings so I can get these devices to just work?
    It's a real bummer to have no information from Apple to update the Time Capsule user manual and help files for what obviously is a common problem in setting up a mixed wireless network.
    Thanks for the help.

    You are right of course.. it is about time Apple updated Time Capsule both hardware and instruction for usage on v6 utility. I wonder if TC is doomed in the future which apple sees is all cloud.
    You can load 5.6 into mountain lion.. you cannot run it as the application installer will fail. But it is still easy to get it working.
    Download the 5.6 package.
    Download unpkg http://www.macupdate.com/app/mac/16357/unpkg
    Run unpkg
    Open the dmg and drag the pkg file over to unpkg.. the 5.6 utility will be loaded to a directory on the desktop. Drag the file to your utility directory.. you only need the main file.
    But it could be even easier to just download and install the airport utility for windows.. which will have bonjour for windows. Plug into the TC by ethernet.
    Whichever way you do it.. change the TC name and wireless names to SMB compatible.. ie short, no spaces and pure alphanumeric.. no apostrophe.. that absolutely ghastly Apple invention.
    Set a workgroup name in the file sharing. WORKGROUP generally
    Set guest account to read and write.. at least initially as it is easier by far to get access.
    I would also lock channels and if the computer uses 5ghz then give 5ghz wireless a different name.. The band swapping is only for Macs.

  • How to use AX1 for wireless audio and Time Capsule simultaneously?

    I am trying AirFoil to Stream Pandora (Safari) to an amplifier and speakers in the next room connected to an older Airport Express.
    I can play iTunes 11.0.1 (on a MacMini 2.26 GHz running 10.6.8) to this older Airport Express 802.11g (before N came out  - Is this called AX1st?) with the audio out the Express connected to my amplifier and speakers and wirelessly play my music. To do this I have to choose the Airport Express as my network device which means I loose my Time Capsule, which is the device with my internet connection.
    Can you tell me how to stay on the internet with Time Capsule and stream to this Airport Express?
    If I try to extend to this Airport Express I get an error message: "The Network You Selected cannot be extended." (I don't know if that is a "g" "n" thing or what?)
    Do I need a newer Airport Express, or a Netgear or how to get Pandora to an amplifier in a different room, wirelessly?  Then the question will be, how to do this to three different amplifiers in three different rooms.

    How do I
    Make your Express 'join' your Time Capsule's WiFi network in AirPort Utility. This will work wirelessly however your Express will not function as an extender in this mode.
    I'm Using Airport Utiity 5.6.1
    In AU in "Aiport / WIreless tab" I hoped it would be as simple as the word 'Join' showing in the Wireless Mode drop down. But it does not.

  • DHCP stopped working for wired clients (possibly due to new Windows 8 machine on network?)

    My home office network has always been rock solid but has suddenly stopped allocating DHCP addresses to wired clients (wireless still works). The only thing that has changed has been the introduction of 2 Windows 8.1 laptops for my children over Christmas, and I wonder if these are the cause?
    My network set-up is as follows...
    I have a fibre broadband connection into the home office which plugs into my Airport Extremes WAN port. I then have a single ethernet cable going from one of the LAN ports on the AE to a gigabit ethernet hub, into which I have 10+ machines. The AE is set to use PPPoE to get the net connection and the network setting is to use DHCP to sign addresses. The IP addresses are assigned to the wired clients, plus a couple of airport expresses, and a number of iPhones, iPads etc. This has all worked fine for a couple of years, and any device just gets an address and works.
    At Christmas both my children got Windows 8 laptops (don't ask!). I connected them to the wifi network (served by the Airport Extreme) and they got assigned an IP address correctly. They can browse fine, and also auto-updated to 8.1 at the same time.
    I wasn't working in the home office at that time but did notice a few things not connecting and when I did check, none of the wired devices was receiving an IP address. They all come up as self-assigned. Nothing has changed on the network itself, the cables are still plugged in (the machines haven't moved!). I think somewhere on the network a second DHCP server is running, but I cannot see where. The only new thing are the Windows 8 laptops. Could they be the problem?

    I've managed to spend some time testing and here is what I found out.
    Before doing anything I turned off the two PC laptops to make sure they were not available
    I powered down the Airport Extreme and disconnected the ethernet cable in the LAN port
    I powered on the Airport Extreme
    I then connected my laptop (running 10.10) via a single ethernet cable to one of the LAN ports. The laptop had wifi off.
    I checked the network control panel, and I had a valid IP address via DHCP. I checked a couple of websites and was able to view them.
    I then unplugged the ethernet cable from my laptop and plugged it into my ethernet switch (keeping the there end in the same LAN port on the AE). No machine on the network was able to get an IP address via DHCP, they all came up self-assigned.
    I then unplugged the ethernet cable from the AE LAN port. I unplugged one of the cables from the switch that goes to a second switch on the network and plugged that into the same AE LAN port. All the machines connected to that switch came up self-assigned and won't get an IP address via DHCP.
    In summary, if a single machine is wired to the AE it gets a valid IP address via DHCP. If multiple machines are connected they don't.
    With the Windows machines turned off, I now thinking they might not be the cause. BUT nothing has changed on the network to make this happen.

  • Time Capsule only works for one device at a time, how to make it capable to be used for multiple devices at times

    Time Capsule only works for one device at a time, how to make it capable to be used for multiple devices at times.
    Please help to set it up, thanks in advance

    You need to give more info..
    Firstly only works for what.. networking.. backup.. wireless. You need more nouns.. more adjectives... describe what you want and what fails.. then we can figure out why.
    Most likely you have bridged it when it should be in router mode..
    Most likely you are using Lion or ML which has the airport utility bridge the TC by default.
    Change it to working as a router. That might help.
    If you press reset button it will default back to router btw.
    If you are on Lion.. use a real utility. http://support.apple.com/kb/DL1547

    One possibility is that your hard drive is failing. If you don't have backups of any data you don't want to lose, that needs to be your number one priority. Get that data backed up. Once you have done that, you can start exploring options.
    Open Disk Utility, select your hard drive and take a look at the SMART status:
    If it says anything other than Verified, the drive is definitely failing. If it says Verified, all that means is that it isn't failing in a way that the drive can detect.

  • ITUNES ONLY WORKS FOR 5 MINUTES AT A TIME

    iTunes stopped working about a month ago, but then I fixed it using the msconfig solution. It worked for a while now I have the same problem, i can fix it, but then iTunes only works for about five minutes before closing. This is the only way I can fix it; first, by re-installing iTunes, then, doing the msconfig solution and restarting the computer. Then after about 5 minutes it closes. To open it again I have to go through the whole proccess. I cannot figure out how to permanently fix it.

    Sounds like you have some malware that is interfering with iTunes.
    What do you have to turn off in msconfig to get iTunes working?
    It's pretty involved to remove it. If you have purchased security software like Norton or McAfee, I suggest contacting them for help.

  • Wireless 3850 and Web-Auth for Wireless clients

    Hi
    I can't get the web-auth feature to work properly on the Catalyst 3850 for wireless clients.

    Issue is when I enable the webauth feature on the SSID. Incidentally when I enable the SSID to use consent it works.
    I am using local authentication for the guest users.
    When user logs onto the wireless, they get to the landing page, and are able to enter the credentials then there is a 30 second pause. The client detail says WEBAUTH_PEND and then a pop up window comes back as seen below

    I saw windows clients take a long time to load the page when using a self signed cert.
    MAC clients dont seem to work if you use the IOS or OSX based logon. You'll need to disable the auto logon and launch a browser for the redirect. There was a bug ID around this MAC problem which was supposedly resolved in 3.3.1SE  but I still have the problem.

  • Exporting PDF files on CS5 - hyperlinks to URLs only work for first page

    I'm new to InDesign and am working through the "Classroom in a Book" training workbook for CS5, I 've got to lesson 14 and have found that when exporting to PDF (interactive) format, the hyperlink to a URL only work for the first page of the document.
    I made my own document with links on multiple pages, and the same thing happened. I followed the lesson to the letter (3 times!)
    I also tried setting up individual links for individual pages and that did work, so how do I get one piece of text to link to one URL on multiple pages of a document (ie on a Master page) ???

    Thanks Peter,  I've actually got CS5.5, so I presume this patch is already updated on this version, because when I tried the 7_0_4 patch it wouldn't run; giving the message: "Some updates failed to install, and "update is not applicable". So I tried the latest update: 7_5_2 patch, but I'm still experiencing the same problems with hyperlinks not working from the Master pages.

  • Trusted Sites GPO only works for administrators

    I've got a major problem and was hoping somebody could help me.  I've got a hundred users or so that connect to an RDS Farm. The RDS farm is made up of several Windows Server 2008 R2 servers.  One with IE 10 and the other with IE 8.
    The problem that I'm having is if add sites to zone assignment in group policy and add sites to the trusted zone it will only work for users that are administrators.  I found a reference to this problem and the issue being IE Enhanced Security, but
    Enhanced Security is turned off.
    If I'm a normal user with Remote Desktop User rights and I go into IE and check Trusted Sites, there is nothing there.  If I login as administrator and check I can see all the trusted sites.
    Anyone know how I can fix this?

    Hi Cyprus,
    Please check if you have the computers or users needing the policy are in a group that is specified. Remember that domain users includes all users, domain computers includes all computer, and authenticated users includes both users and computer. By
    default, a GPO will be scoped to Authenticated Users.
    Also please run gpresult command on non-administrator user to check if it sync to client successfully.
    In addition, I suggest you ask Group Policy forum for more professional help:

  • Flash player only works for user account installed with

    Hi all
    I've different user accounts on my PC for me and my son.
    Somehow Flash Player 10 only works for the user account I installed Flash player with.
    In case I install it using my account it will not work for my son's account and vice versa.
    How can I solve this?
    Thanks

    I've struggled with this for a long time.  Here is what I've come up with.
    Adobe tech support recommended this:
    1. Log in as Admin
    2. Download the following zip file from here:
    www.supportflash.com/reset_all.zip
    3. Unzip this folder onto your desktop.
    4. Drag both files ‘reset_min_all.cmd’ and
    ‘subinacl.exe’ to your
    desktop.
    5. Run the reset_min_all.cmd file.
    6. It will open a DOS like terminal and start
    running through registry
    keys.
    7. When it is finished it will say “press any key
    to continue”.
    8. At this point you can install the latest Flash
    Player:
    for Internet Explorer:
    http://www.adobe.com/support/flashplayer/ts/documents/tn_19166/Install_F
    lash_Player_9_ActiveX.zip
    other browsers:

    9. Check that Flash Player is working for the
    Admin.
    10. Check that Flash Player is working as the
    other 2 users.
    I hope this information helps. Feel free to reply

    I can't recall whether I had to run this in each account or not.  It somewhat worked for me.  If the accounts were all set up as admin accounts, flash worked in all the accounts after that.  If one account was admin and the rest were limitied (I'm running xp home) it wouldn't work in the limited account.
    I gave up and reverted back to flash player 9 via NOrton go back
    It must be a permissons issue of some sort.  I just don't have the patience to figure it out.
    Good Luck,
    Let us know what you figure out

  • Initial configuration of ACS 5.1 for EAP authentication for Wireless clients

    Hi,
    I have set-up with below devices :
    Wireless LAN controller 5508
    LAP 3302i
    and ACS 5.1
    since i am new in ACS 5.1 configuration , I need so information to go ahead to configure ACS 5.1.
    which EAP method to use for wireless client authentication ? what is the best practice ?
    I have gone through some cisco documents and it shows that best practice is to configure PEAP but for the same , I need to install certificate in ACS server as well in client PC. is that so ?
    I have no clear picture for this certificate ?
    from where i can get this certificate or do i need to purchase this certificate separately from cisco. how to install it in ACS server ?
    I will be obliged to get atleast initial configuration for ACS 5.1 to enable the EAP method,
    I need GUI based initial configuration for ACS 5.1
    This mentioned ACS 5.1 is installed on ACS 1121 hardware appliance.

    Hi,
    which EAP method to use for wireless client authentication ? what is the best practice ?
    -> I would advise the most widely spread EAP method, which has the best ratio security/easy to deploy: PEAP with MSCHAPv2, which is available by default by all windows machines.
    I  have gone through some cisco documents and it shows that best practice  is to configure PEAP but for the same , I need to install certificate in  ACS server as well in client PC. is that so ?
    -> You will always need to install a server certificate, however, there is no need for client certificate because the authentication is based on the MSCHAP credentials exchange, not certificate based. The only requirement on the client regarding certificates is the following.
    If you want to validate the server certificate, you have to install the server certificate under the trusted CAs of the clients.
    If you do not require to trust the server certificate, you can simply disable the option of server certificate validation.
    I have no clear picture for this certificate ?
    from  where i can get this certificate or do i need to purchase this  certificate separately from cisco. how to install it in ACS server ?
    -> The server certificate can be a simple self signed certificate that you generate and install on the ACS GUI.
    Please feel free to follow this step-by-step guide on
    PEAP under Unified Wireless Networks with ACS 5.1 and Windows 2003 Server:
