Dhcp settings

I have a cisco 2100 WLC. How to I change the dhcp setting to point to a different dhcp server? I looked in \config\dhcp but all the listing appear to be for creating setting up a dhcp server on the controller and I want the cleint to get their ip address from my internal DHCP server.

You configured this under the interface (Controller - Interface) that is mapped to the WLAN.

  • DHCP Settings keep resetting?

    I've actually had this problem since Server 2 for Mountain Lion, and removing Server and /Library/Server would do the trick, but not with Server 3.1...
    Any ideas?  To be clear, every time I set the DHCP settings and enable the DHCP service, it will reset on reboot.  Sometimes it will reset without a reboot of OS X and suddenly none of my devices can get on WiFi.

    Launch Console.app from Applications > Utilities directory, open the view of all the logs on the left if it's not already open, and see if the DHCP server is logging errors when the startup is attempted.
    Check your local DNS, too.  Launch Terminal.app from Applications > Utilities and issue the following harmless diagnostic command:
    sudo changeip -checkhostname
    This command will either tell you no changes are required, or that there are DNS or network issues lurking.  DNS issues cause all sorts of weird bugs, as can networking problems.
    Also ensure the server is not using .local as its top-level domain.

  • DHCP Settings not showing up

    I have an OS X 10.4 server running 10.4.11 that has been running fairly well for some time. I recently had a need to go in and make some changes to the DHCP settings, but they aren't showing up. Trying to add another subnet seems impossible because the "Network Interface" option doesn't give me any interfaces to choose from. The new subnet doesn't get applied to my interface, so it uses the old settings that I can't see.
    Running 'serveradmin settings dhcp' gives me:
    2008-05-19 12:25:17.494 serveradmin[17130] * -[NSCFArray UTF8String]: selector not recognized [self = 0x31cec0]
    2008-05-19 12:25:17.494 serveradmin[17130] Exception in doCommand: * -[NSCFArray UTF8String]: selector not recognized [self = 0x31cec0]
    Trying to modify DHCP settings using serveradmin also gives the same error.
    From what I've gathered, the DHCP settings aren't stored in their own file, but in the NetInfo database. Is there a way to clear out the DHCP part of this database, or overwrite it with imported settings?
    Thanks,
    -Craig Coleman

    Okay, I used the Netinfo Manager to delete the "dhcp" key under "config" but it still has the same problems, except for the fact that the old dhcp config isn't there anymore.

  • I've just changed my router and whilst my laptops sync ok, my G4 tower which connects via an airport express doesn't connect to the internet. I think it's something to do with the IP or DHCP settings but have had no success, any help much appreciated.

    Hi Jake,
    Is it connecting to the Router or Modem?
    Is the new Router using maybe WPA2 encryption? If so, G4s can only do WPA or less.

  • Anyone else having issues with DHCP settings resetting?

    I think this is a glitch with OS X Server 3.0.1... I have the server handle DNS and DHCP instead of the router, and after a reboot, DHCP settings revert to off and the default Ethernet IP pool.
    I tried the usual, even formatted the hard drive and installed from scratch.  I also deleted Server.app and /Library/Server, then redownloaded Server from the App Store.  I also verified and repaired permissions.

    Bob-
    If you are using the old iPad 1 dock with an iPad 2, there is a problem due to the different shape of the new iPad's bottom.  Some have suggested folding some paper to stuff between the back of the iPad and the dock, to help make better connection.

  • WRT54G cannot save DHCP settings

    Hi,
    My WRT54G will not save changes to the number of DHCP users. I have a static IP address from my ISP and have all of the info entered correctly and can connect wirelessly to the internet from my laptop but not from my wired desktop. I'm guessing it has something to do with the DHCP settings.
    On the router setup page it has the starting IP address as 192.168.1.1 (which is the IP address of the router and shouldn't be the pool's starting address) and the max number of users as 2. If I change the starting IP address to 192.168.1.2 it automatically sets the max number of users to 1. If I try to enter in any other values than those above for the starting IP address, it does not save the changes even though I get that page that says 'settings have been changed successfully' and the 'continue' button.
    I am running Vista on the laptop, XP Home on the desktop and have an SDSL modem from my ISP. I just switched from a Belkin router to the Linksys & both pc's could connect before with the Belkin except it kept dropping the wireless connection on the laptop -- hence the reason for the switch to the Linksys.
    I hope this makes sense to someone out there who can offer some assistance. I certainly do appreciate any help offered.

    You need to reset the router to factory defaults, then setup your router again from scratch.   If you saved a router configuration file, DO NOT use it.
    To reset your router to factory defaults, use the following procedure:
    1) Power down all computers, the router, and the modem, and unplug them from the wall.
    2) Disconnect all wires from the router.
    3) Power up the router and allow it to fully boot (1-2 minutes).
    4) Press and hold the reset button for 30 seconds, then release it, then let the router reset and reboot (2-3 minutes).
    5) Power down the router.
    6) Connect one computer by wire to port 1 on the router (NOT to the internet port).
    7) Power up the router and allow it to fully boot (1-2 minutes).
    8) Power up the computer (if the computer has a wireless card, make sure it is off).
    9) Try to ping the router. To do this, click the "Start" button > All Programs > Accessories > Command Prompt. A black DOS box will appear. Enter the following: "ping 192.168.1.1" (no quotes), and hit the Enter key. You will see 3 or 4 lines that start either with "Reply from ... " or "Request timed out." If you see "Reply from ...", your computer has found your router.
    10) Open your browser and point it to 192.168.1.1. This will take you to your router's login page. Leave the user name blank, and in the password field, enter "admin" (with no quotes). This will take you to your router setup page. Note the version number of your firmware (usually listed near upper right corner of screen). Exit your browser.
    If you get this far without problems, try the setup disk (or setup the router manually, if you prefer), and see if you can get your router setup and working.
    If you cannot get "Reply from ..." in step 9 above, your router is dead.
    If you get a reply in step 9, but cannot complete step 10, then either your router is dead or the firmware is corrupt. In this case, use the Linksys tftp.exe program to try to reload your router with the latest firmware. After reloading the firmware, repeat the above procedure starting with step 1.
    If you need additional help, please state your ISP, the make and model of your modem, your router's firmware version, and the results of steps 9 and 10. Also, if you get any error messages, copy them exactly and report back.
    Please let me know how things turn out for you.

  • What are DHCP settings and what is a DHCP lease

    My macbook has decided to stop logging on to my wifi router automatically.
    Seems the DHCP settings are wrong with an inappropriate IP address and Submask coded applied.
    When I change them back manually to what they were the computer says it is logged on to internet but refuses to open any internet application?
    I have tried the DHCP lease renewal prompt but still will not award appropriate IP or Submask code

    Hi RobertaMcC,
    Are you having trouble with a Wi-Fi connection or a wired (Ethernet) connection to the internet?  DHCP is a communications protocol that assigns each computer a unique IP address on the internet.    I'll include the information you specifically requested first, and general troubleshooting steps as well.

  • Question regarding Airport and DHCP settings

    I currently had a Dlink 624 router that just died. I need to get a new wifi router and was looking at the airport extreme base station...
    the question I have is with Dlink my dhcp is set to send out 192.168.0.xxx to my network. The apple is 10.0.0.xxx I believe. Can you change the airport extreme base station to 192.168.0.1? and serve 192.168.0.xxx across the network? The issue I have is I have other wifi devices that are already preset to accept the 192.168.0.xxx.

  • Help - I changed DHCP settings and cut myself off from my own router!

    In my lame attempt to increase security on my router (WRT54GS) I changed the allowed number of DHCP users from 50 to 4.  As soon as I clicked "Save Settings" I systematically disabled access to the router from all computers in the house, and now I can even get into the router to change it back.  Grr!!  Before I touch anything else, I wanted to reach out for help.  Anyone?
    Solved!
    Go to Solution.

    Hummmm, well if I had to guess I bet you did not hold down the reset button in back for 30 seconds at least and then power cycle the router.  A quick press of the button will not perform a hard reset.  So how did you perform the 'reset' ;-).
    Wireless security can be found here.  Pick which level you want.  Glad you got it going.

  • How do I change the dhcp settings in the Airport Utility?

    I have a Time Capsule, 7.6.1 firmware connected to my DSL modem which uses PPPOE to connect to the internet.  The router mode of the Time Capsule is DHCP and NAT. The Time Capsule serves several static addresses to my clients, and to guests as needed. What I've noticed is that the DNS address is incorrect, it the IP address of the Time Capsule, not the address of my DNS, which is on the local LAN. I can see where I can change the values that are served out. Can someone help me out?
    Thanks

    Well, I think your problem or doubt is solved. But I have a situation here.
    My TC is connected to my ISP router and it uses DHCP to obtain the internet ip and dns from the ISP router.
    My TC is configured to serve my wifi clients using DHCP too.
    Everything is fine..
    In my client wifi computers, I can see the IP (something like 10.0.1.25 to 10.0.1.65) - that´s my range. My client computers also get the default gateway and DNS (10.0.1.1) -- that´s my internal TC IP.
    The problem: I want to use, in my client wifi devices/computers the DNS of my ISP or anyother I want. In desktop computers and some devices, I can go and change only DNS and continue to use DHCP (from time capsule) but in some devices, I can´t change only de DNS and they are forced to use 10.0.1.1 DNS address served by time capsule.
    Why I want to change? In my desktop computer, I can see that if I use my ISP DNS direct on my network adapter instead of use 10.0.1.1, every internet access is much, much faster. I don´t know why, because, in theory, the TC is just forwarding the dns requests from my computer to my ISP DNS, but I think something is not working as it should and using this Time Capsule relay, is costing me some valable time.
    Can I configure Time Capsule to serve a specific DNS address to wifi clients, instead of its own ip address?
    Thanks.

  • Bug report EA6400 LAN IP - DHCP settings

    Dear reader,
    I'm not sure I'm in the right place, but I want to report a bug in the EA6400 firmware.
    Firmware version (latest at this time and date):
    10/16/2013
    Ver.1.1.40 (build 153731)
    Problem for short:
    Routers IP address cannot be changed with DHCP server disabled.
    Problem in detail:
    When configuring my EA6400 router, I could not change the network portion of the Routers own IP address (192.168.1.253 to 192.168.2.253) while I had the DHCP server disabled.
    The router showed an error message about the IP address (something about it being invalid).
    After enabling the DHCP Server (and making sure the range doesnt overlap with my current DHCP server) and applying the setting, the routers IP address could be changed.
    With the IP address of the router changed, I disable the DHCP server function.

    Hi DvanBavel! Thanks for letting us know about this. As far as I can remember, when setting up LAN to LAN network  where I had to disable the DHCPS server also, I always change the router's IP address first. It is because as soon as I disable the DHCP server on the router's IP, the page closes right away and I am unable to access it again. I didn't know that this was a bug though. Let's wait for others to comment. 

  • WLC DHCP Settings - Under Dynamic Interface configuration

    Hi Guys,
    If I have a dynamic interface that is connected to a subnet where the router interfaces have DHCP servers configured under the helper address commands, do I need to configure the DHCP fields under the dynamic interface configuration?
    I have helper address configured on the connected routers AND these fields configured with the same DHCP servers.
    Just wondering if I can take the IPs out of the WLC configuration?
    Many thx indeed,
    Ken

    Ken, the DHCP address under the dynamic interface, is the address the WLC will unicast the DHCP request to when a client tries to use that interface. Under normal operation this address is needed. There is a way to get the WLC to bridge the packet to the wire so that it is a broadcast instead of a unicast packet. CLI command is config dhcp proxy disable.
    But I do believe that even if you issue the CLI command, the software wants the DHCP address listed under the dynamic interface.
    HTH,
    Steve

  • Dhcp settings are being overwritten by PC

    I had a fiber optic connection installed with a wireless router for my daughters computer. The router is DHCP. Every time the installer tried to connect to the wireless router with my G4 PC using a cable the proper codes would be over written by my computer in less than a second. How can I get my apple to stop this.

    Not quite sure what you mean by "installer" (the guy that installed the fibre optic?) but previous repsonse is correct that you should check that internet connection sharing is off - part of the effect of that setting is to make your G4 a DHCP server on a subnet of 192.168.2.x - if the other system is getting an IP address along the lines of 192.168.2.2 that is your problem. And if you have just upgraded from a connection that you were sharing to a peer-to-peer enviroenment with a separate router/DHCP server this is very likely the answer.

  • Time Capsule DHCP settings

    My BT Home Hub 2 started playing up so I replaced it with a Draytek Vigor 120. I have managed (somehow) to get it to work and have internet access despite the Vigor saying that I don't.
    The Time Capsule DHCP is assigning IP addresses of 10.0.#.# instead of 192.168.#.# - any ideas how to change this format?
    Thanks.

    A consumer device with an LED labeled as an essential funtion but is actually redundant? This is why Apple should do their own ADSL modem...
    It is not redundant.. The internet LED will light when the draytek is used as router.. it then handles the routing.. but the UK version has removed that option.. this is correct because the internet is not controlled then by the modem.. only dsl sync. The router that does authentication, actually is the internet device..
    Apple have never made anything beyond dial up modems and they will never make adsl modems.. which are going to eventually be phased out hopefully as we go to fibre or vdsl.
    A bridged modem is not generally accessible from a router.. the WAN port of the router is pppoe encapsulated not normal IP addressing.

  • DHCP settings - use 10.0.x.x

    Hello
    I'm considering buying a ea6500 for our home / office network.
    Our current network uses the IPs 10.0.x.x
    We have a DNS server running on the network and it would make the transition a lot easier if I could set up the new router to dish out 10.0.x.x addresses.
    Does anyone know if this is possible or am I stuck to 192.168.x.x?
    Thanks
    Andrew
    Solved!
    Go to Solution.

    Many thanks for the reply - really helpful.
    I'm hoping I can set the new 6500 router to 10.0.1.1 as our DNS servers are 10.0.1.2 & 10.0.1.4 - but it sounds like that should be possible. We then have the DNS Servers forwarding to OpenDNS any unresolved requests. I assume the 6500 lets us use our own DNS servers?
    Also - I'm unlikely to use the 6500 as a Wireless access point - most likely going to use it as the (sole) router in the network - as where it will be located is a long way from where we use our wireless devices mainly. I then have some Apple Airports plugged into hardwired connections near to where we need to use the WLAN.
    Will I still be able to see all devices through the 6500 even though they are not connected through the ea6500 WLAN? (they'd be connected to the ea6500 through a different WLAN which is then connected through the hardwired connection)
    Any help much appreciated!
