AP Controller IP DHCP Problem

Dear all,
its not my first config or location but with the 2600 I have now a problem.
Any ideas?
*Mar  1 00:17:04.255: %CAPWAP-3-DHCP_RENEW: Could not discover WLC using DHCP IP. Renewing DHCP IP.
*Mar  1 00:17:07.327: %DHCP-6-ADDRESS_ASSIGN: Interface BVI1 assigned DHCP address 10.X.Y.101, mask 255.255.255.0, hostname APc08c.6024.cfc8
Translating "CISCO-CAPWAP-CONTROLLER"...domain server (255.255.255.255)
*Mar  1 00:17:14.255: %CAPWAP-5-DHCP_OPTION_43: Controller address 10.A.B.30 obtained through DHCP
The AP will use the 10.A.B.30 as Controller...when I enter the Controller IP manually it works..
best regards,
Sebastian

    Hi All,
    My wireless network system is consisting with 7.5 virtuall wireless controller and few 3600i APs.
    All SSIDs & APs have been configured in flexconnect & flexconnect groups.
    APs acquire IP address & controller IP address via DHCP option 43.
    My problem is,
    After I created a new SSID & pushed it. APs don't reboot itself but disconnecting from the controller and never come up back until give a manuall power reboot for each APs.
    * DHCP server has not been configured any authentication mechanism for APs.*
    I got below console outputs:

    Anybody know the reason for this behavior ?
    Thanks,
    Charith

    Hi Charith,
    It's looks like AP goes into Standalone mode due to it cannot reach your WLC. In flexconnect when it cannot reach WLC, it will go into standalone mode without rebooting AP. (in local mode AP will reboot unless it can find a WLC)
    Can you check your AP has reahability to your WLC all the time ? Where the DHCP configured for users ?

  • How to resolve DHCP problem in Oracle for Cent OS

    Hi everyone,
    I want to install Oracle 10g on my new linux os CentOS. At very first step of system check, it warns me about having DHCP enabled and to use some static IP insted.
    I have already done loads of installation on my windows box so I know how to deal with DHCP by using Microsoft Loopback Adapter.
    But I dont know if there is any Loopback adapter available for Linux ? I have tried already to google but it seems that its really difficult to find the correct installation methods because most of "How tos" just ignore the fact that , web interface of EM won't work well with DHCP ( as far as i know :D ).
    So, is there any work around for this DHCP problem ? I mean linux version of microsoft loopback adapter !!! ... Also do I need to say that , its my laptop and I use it on various networks including starbucks and DD ;) ... so I guess , I can't go for configuring static ip for my physical card. my knowledge for linux is a bit primitive so it will be really appreciated if you can provide me step by step instructions.
    BTW, regardless of warning i have installed Oracle 10g, and as i had expected .... Web Interface of EM gave me an age old error ( web page not found ) when I restarted my laptop... which is because of DHCP.
    Thanks in advance for any help
    Peace,
    Jack

    Thank you guys for your advice. I really appreciate it.
    But this does not solve my problem. I dont know weather you guys know or not , CentOS is EXACTLY same as RHEL other then "support" thing. So I dont see any reason to switch from CentOS to RHEL. Another reason is , I have already installed CentOS on my separate partition , so I dont want to go to through all of that again :D .
    And even if i think to change to OEL( i have downloaded it already ) or RHEL , problem still exists ... " DHCP " ... how do i deal with it ??
    for my friend damorgan,
    a fixed IP address is preferable but if you need DHCP for some reason just do the install, build your database, and then modify the listener.ora and tnsnames.ora to point to 127.0.0.1 for the host. , I know I need fixed IP, but if I am installing it on my laptop and just for study purpose, Its really not useful to setup static IP and as i wrote in OP, life of student is very adventurous and we never stay at one place right ? so, its not possible to have static IP for me ( unless i use it with VMWare or something like that ) .... now question is, what is this 127.0.0.1 ip you are talking about ? Do i need to add it into HOST file ? A little brief explanation will be helpful here :) ... this stuff is damn easy with windows and i am sure that linux should have have work around of DHCP. I am writing LINUX , instead of going in to specific flavor because i think the solution will be same only the method will change, right ? .
    I also looked at the link David posted here , (to be honest , I have not gone through all OSes setup help ) , I can not find even a line mentioning about DHCP Problem. May be I am missing something , David can you point me exact link (if there is any) ?
    Any more suggestions guys ?
    Peace

  • WRT54G (v5) DHCP problem (MAC, APPLE, MAC OS) -- How to fix it

    Ok, so I just got some instructions from Linksys support and apparently definitely got rid of the DHCP problem. Here they are:
    Please reset the router before and after the upgrade.
    To reset the router (make sure that the modem is disconnected when doing a reset):
    1. Locate the reset button of the router at the back panel.
    2. Hold the reset button for 30 seconds using a pen or a paper clip.
    3. Release the reset button and unplug the power adapter of the router.
    4. Leave the router off for 30 seconds then plug it back in.
    Click the link below to download and save the firmware:
    http://www.linksys.com/servlet/Satellite?c=LDownloadC2&childpagename=US%2FLayout&cid=1115417109974&packedargs=sku%3D1127782957298&pa gename=Linksys%2FCommon%2FVisitorWrapper
    To do a firmware upgrade, you can follow the steps listed on this link:
    http://linksys.custhelp.com/cgi-bin/linksys.cfg/php/enduser/stdadp.php?pfaqid=557
    Reset the router again after the firmware upgrade. You can then reconfigure it for Internet and wireless connection.

    Hi, Malcolm:
    Thanks for the post.
    No, my new Mac Pro system does not have USB port on the Keyboard, cause I've opted for Apple's wireless blue tooth mouse and keyboard.
    I do have 2 USB ports on the Apple's 23" LCD display, and Two USB ports on front side and two available USB ports on the back of the Mac itself.
    During the Thanksgiving long weekend, I think I might accidentally singled out the cause of my problem.
    I have my HP printer and one multi-card reader constantly pluged into the two USB ports at the back of my Mac, and always tried to use the front side USB ports for the 1GB USB Pen Drives, and that's where the problem lays!
    When I unplug the Multi Card Reader from the back USB port, and suddenly all USB ports on my Mac works just fine with the Pen Drives!!!
    So, for now, I plug the Multi Card Reader in one the the front USB port, and the rest of the USB ports on the Mac work with Pen Drives flawlessly, it seems that I sloved my problem for the time being...
    As for those two USB ports on the back of my 23" Apple Display, They can not take my USB Pen Drives, as you've mentioned that it does not have enough power for the USB Pen Drives.

  • WRT54G V6 DHCP Problem

    I have a WRT54G V6

    and useing MAC Filering
    i have 1.02.2 7/02/2007 Firmware for the WRT54G V6

    The firmware is the most current one on the site. There are no other options than that. Anyway what kind of DHCP problem are you having? Is your laptop getting "limited or no connectivity" when you try to connect wirelessly to the network?
    Don't use AES. Most cards are only compatible with TKIP.

  • DHCP problem with wireless clients

    I've just set up this eqipment
    Router/Firewall ASA 5505
    Cisco WLC 2125 - Wlan controller
    Switch Catalyst 2960
    16 Ap's  AIR-LAP1131AG-E-K9
    Everything was working fine, but after a while there was a problem, spesially with cell phones with wlan and with some laptops. It seems a part of the users that has been connected, then loggout out and try to log in again. It seems that they then dont get dhcp. Can this be a problem with dhcp on the asa 5505? Or does anyone know of any settings that create problems of this type.
    Trond

    One layman's question:
    For DHCP to work, you already permit 0.0.0.0 to ask 255.255.255.255 for its IP adress (i.e port 67 in one end, and 68 in the other).
    When a client re-attaches ("logs in again") it will try to use its old adress (the one assigned by dhcp) and ask 255.255.255.255 to renew its adress.
    Does your ACLs permit the IP range assigned via DHCP to access 255.255.255.255?

  • 2100 wireless LAN controller intermittant DHCP issue does not respond to clients

    Hi everyone,
    I have been struggling with a difficult problem for some time now:
    The cisco 2100 wlan controller I have is configured with a dhcp scope in the same ip address range as its WLAN. The configuration works and on a good day I have up to 200 clients connecting with out issue. In the web interface they display as associated and authenticated
    On a bad day I find I will begin seeing about 50-80% of all new devices that attempt to join the WLAN show up as associated but not authenticated. These clients end up self assigning themselves a 169.254.0.0/16 (APIPA) address
    When my controller / WLAN enters into this state: if clients leave the WLAN they typically fail to get back on and successfully authenticate. By the end of a day around 80-90% of all devices are essentially without Internet access due to this issue.
    Rebooting the controller and or APs typically makes no difference or makes things worse – although sometimes it appears to resolve the issue. The same holds for disabling the entire wlan for about 10 minutes and then re enabling it.
    Im using 1130 cisco aironet APs with the controller. I have checked extensively for interference and congestion – I think I have congestion – some APs typically host 40 to 90 devices. However as mentioned on a good day the wlan will host 200 devices all day without any issue and some APs will host 50 to 70 devices without major issue.
    I can provide more specifics if anyone should need – eg firmware, IP addresses, exact model numbers etc.
    Please let me know if anyone has seen something like this before ?
    I believe the 2100 is rated to handle up to 350 devices and its recommended not to load a 1130 AP with more than 25 devices ??
    Regards
    Matthew

    Hi Amijad, Hi George:
    Thank you both for your time in considering my situation.
    I will think about implementing an independant DHCP server; im really wondering if the equipment is just overloaded
    - What software versoin the WLC uses?
    Product Version.................................. 6.0.199.4
    RTOS Version..................................... 6.0.199.4
    Bootloader Version............................... 4.0.191.0
    Emergency Image Version.......................... 6.0.199.4
    PID: AIR-WLC2106-K9, VID: V05
    - What ports of the WLC are connected to the neighbor swtich? one or more?
    2 ports connect to the neighbor switch on separate vlans
    - port 1 is vlan 0 and hosts the management and ap-management IPs for the wlan controller
    - port 2 is vlan 1 and hosts the wlan
    - the controller has one dhcp scope defined on port 2 for the WLAN
    - What is the security of your WLAN?
    WPA+WPA2
    AES
    PSK
    - Do you have "DHCP required" enabled on the WLAN?
    yes DHCP required is enabled in the WLAN
    please let me know if you have any additional advice.
    regards
    Matthew

  • VWLC and dhcp problem

    Hi, I have some problems with dhcp.I have 8.0.100.0 vWLC. My ap joined to the controller. Clients connected, but cannot receive ip address. I know, what are exist some methods to receive address, with DHCP Proxy Mode and without, then you just need to prescribe ip helper-address on int vlan. I try both of them, but nothing helps. 

    You are using the vWLC, which means that all your access-points should be in "flex-connect" mode. My advise is to make your SSID's "local switched" so that the client traffic gets bridged on the switchport (dot1Q trunk) directly. Than you need to configure the VLAN ID's on the access-point or flex-connect group in the WLC. If you have all the this configuration in place, you need to configure some DHCP relaying on your SVI (vlan interfaces) so the the client can actually gets an IPv4 address. I recommend to uncheck the option "DHCP required" on the SSID on the WLC.
    This should get your network running. If it still does not work I would start troubleshooting on the WLC to see if the client is actually associated and authenticated (if you don't use any L3 security mechanism) if that is the case you should see the clients MAC address on the switchport. If the client by then still does not receive an IPv4 address, you need to troubleshoot the DHCP / SVI configuration on the switch/router and even maybe on the DHCP server itself.

  • DHCP Problem with ASA 5505

    Hi. I have an ASA 5505 configured for Transparent Mode. The Outside interface connects to a router (RV042). The router manages DHCP. With the 5505 in the system, all computers can connect to the internet and to each other, except for a few. The problem computers can be made to work if they are set to a specific address, rather than automatically assigned by the router. Some of the iPads work correctly, some do not. At least one Apple Notebook cannot connect even if I enter a static address.
    Consulting the documentation, I found that DHCP traffic (UPD Port 67 and 68) needed to be enabled via rules for the Inside and Outside interfaces. I did that in ASDM but now nothing works.
    I have pulled the 5505 out of the system and restored it to the configuration that worked for most of the computers.
    Any suggestions would be appreciated. I can pull a "show" run from CLI if it is useful.
    Thanks...

    Understood. I tried adding the "inside_out extended permit ip any any" command, but it made no difference. Because the implicit rule (permit ip traffic to any less secure interface) is still in the access list table, it would seem the additional extended rule is not needed.
    When I first received the 5505, it had an older version of firmware. At the time, when I entered any rule in ASDM it deleted the "less secure" implicit rule, which then broke the system since there was no path for internet traffic from inside to outside, as you have stated. With the newest firmware release, however, when I enter a rule, the "less secure" implicit rule does not go away.
    So, with help from the folks here I have made progress. Right now the issue is that when the 5505 in Transparent Mode is between the router and user computers, the computers cannot reliably get addresses that are auto-assigned by the router.
    Looking through the logs displayed on ASDM, I noticed the following curious statement:
    "6 Mar 31 2014 07:16:42  fe80::1131:41c2:3627:8339 63575 ff02::1:3 5355 No management IP address configured for transparent firewall. Dropping protocol UDP packet from outside:fe80::1131:41c2:3627:8339/63575 to inside:ff02::1:3/5355"
    However, I have configured a management IP address, and it is listed in the "show" document that I posted yesterday:
    interface BVI1
     ip address 192.168.1.10 255.255.255.0
    So, I am confused.
    I appreciate the help. I am new to the 5505, although I participated as a "friendly" in the ASA program some years ago. I recall a similar problem with that setup. Regrettably, I can't remember how we fixed it...
    Regards...

  • VirtualBox 4.0.2 internal DHCP problem in Host-only mode?

    Hi,
    dos anyone have experience problems with VirtualBox 4.0.2 internal DHCP not working when running Oracle Linux and a Host-Only adapter.
    More detailed described my problem is that Oracle Linux don't get a ip from the internal DHCP server om my system. My host is Win 7 (64 bit) and Guest Oracle Linux (64 bit). I have read that there are several ohers who experienced the same problem with the open source version, but that patching the Guest Tools to 4.0.3 helped them. Sadly this is not the case for me. Any suggestions are welcome and thanks in advance.

    Thanks for your reply - my problem is that the build in dhcp server is not working for some reason and i dont't gen any ip address assigned. I can see from the VBoxManager that it is running, but i can't get i contact with it from the linux guest.

  • Self Assigned IP / DHCP problem : sharing my fix.

    Okay. I WAS frustrated for a long two weeks before I figure this out. It seems that this problem has affected a LOT of people out there, and since I now am (supposedly) free of this thing, I want to share my hypothesis of the problem's roots (A) and my fix (B).
    Note that:
    - i'm free of this problem since the last one week, so .. well, hopefully this is right.
    - the problem happens almost anywhere, with any router types, and in any connection type, be it ethernet or wireless a/b/g/n.
    - the problem is automagically fixed by running into safe mode.
    - the problem keeps happening again and again, although you have powercycled everything of the electronic peripherals in your house, even by disconnecting your phone/ADSL line and main power fuse.
    - disabling the Mac OS X Application Firewall sometimes cures it, but most of the time it happens again.
    - AFAIK (correct me if i'm wrong), the ipfw, mother of all OS firewall, exists within Mac OS X, and the Mac OS X Application Firewall (i call this OSXAF) has nothing to do with ipfw.
    A. My hypothesis and the reasons.
    * for an unknown reason, there is a rule created for ipfw that tells it to block the ports 67 and 68, both are the common DHCP ports.
    * because of that, your Mac cannot contact with any DHCP servers, anywhere. This forces your mac to assign an IP address by itself.
    * disabling OSXAF incidentally removes that rule, but after (one or a few times) reconnect or reboot, the rule appears again.
    * powercycling your routers or anything related does not concern ipfw, thus has no effect whatsoever to the problem.
    B. My fix.
    1. Get the WaterRoof free ipfw frontend (forgot the site, just google)
    2. Open it.
    3. Go to Static Rules part.
    4. Find everything which reads "deny blah blah blah port blah,blah,67,68,blah blah"
    5. Edit those rules so that there is no 67 and 68 inside.
    6. Open tools -> rules configuration -> save to startup configuration -> yes.
    7. Open tools -> startup script -> install startup script -> yes.
    That's all.
    For me, this seems to be a permanent fix. Please note that the startup script mentioned before exists in all *nix-based machines, so don't worry about startup time, there'll be no slowdowns (again, please correct me if i'm wrong, i had only little experience with *nixes). Besides, i suspect that if you don't save and reinstall that script, the previous script is the one which has 67 and 68 inside.
    Hopefully this helps. Any corrections, comments, suggestions, and/or knowledge are welcome.
    Cheers,
    -bam, the noob.

    OK, so a little background -
    I have an MBP with 10.5.5 (which I downloaded yesterday, so that's not the issue). This year at school they upgraded the wireless system and network control to Foundry routers and Bradford Securities Network Control. Problem is, my computer is intermittently and randomly having a hard time sticking with one IP and staying away from a self-assigned 169 IP. The System Prefs are fine, and even when I change to manual settings for the IP, it doesn't stick. I checked the terminal (tcpdump) and it seemed to be having a tough time accepting one of the two IPs the servers offered (there are two servers for redundancy). It asked for an IP, gets two offers, and then asks again. I was stumped, and so were the IT guys on campus. And it's not just me, many other 10.5 users are having the issue. And it's not the network, because nobody else is having the issue but 10.5 users. Certificate problems are similarly eliminated from possibility.
    The IT guy showed my this thread, and I was excited, so I first tried to just shut off the Firewall all together, and that worked, briefly, but now it doesn't matter if the Firewall is on or off, the problem persists. I tried your WaterRoof method, and the similar program NoobProof, but there were no rules relating to ports 67 or 68 at all, let alone denying them. (As a side note, when my FW is off, there's only the rule allowing all IPs in and out, and when it's on (but only allowing specific programs) it gives a second rule that denies "icmp from any to me in imcptypes 8." No idea what that means.) I've been watching tcpdump and the FW logs closely (as well as the console itself), but nothing has changed. The only interesting thing is that when the IP changes from the (good) 137 IP I'm supposed to have to the (bad) 169 IP, often times (in fact, most times) there is no firewall activity. The console says that the en1 link (wireless) is now down, and the tcpdump picks up the computer asking for an IP again, but the firewall logs pick up nothing, neither through the console or through WaterRoof. Which is weird, because I thought it was a FW problem (as did the IT guys), but the logs show that only occasionally when the servers offer me an IP does the FW block the request, but not all the time.
    As another point to note, this is not only an issue with the wireless. The wired connection (Ethernet right into the wall, and attempted from many different plug-in sites) also has this issue.
    My only conclusion is that the FW is buggy, or that the logs are missing denials, neither of which makes much sense, IMHO.
    Any thoughts?
    EDIT: Shutting off the FW often solves the problem, but not always. Sometimes I can get a correct IP even with the FW in full swing without anything popping up in the logs. And sometimes I can't.

  • RAID controller on G4; problems... is RAID dead? Help please!

    Hey.
    Here's the deal... Our graphics department has a MAC G4 (fully upgraded. newest patches, OS, etc.) that's got a 4 port SATA RAID controller. They use this with four 750GB hard drives as an external RAID (the OS is on a seperate, 65GB hard drive). The way it's set up, through Apple's OS, is we have the four 750GBs in pairs... those pairs are striped, and then the two sets of striped 750s are mirrored. This has worked just fine for a number of months, but we recently had a power surge, and now we're unable to mount "Monkey" (the name of the 1.4TB array).
    See the below screenshots for more clarification.
    http://www.amcdoors.com/lorenzo/raidsetup.JPG
    This shows the RAID card, and the four SATA cables coming out of it.
    http://www.amcdoors.com/lorenzo/leftside1.JPG
    As you can see in this and the below screenshots, this shows the 1.4TB Striped set as 'online', but the two below (the two 750GB hard drives) show up as "offline".
    http://www.amcdoors.com/lorenzo/leftside2.JPG
    this shows the actual drive i click on. same thing
    http://www.amcdoors.com/lorenzo/leftside3a.JPG
    If i click the entire array, you can see how it's set up (the Mirrored RAID set consisting of the two Striped RAID sets). The RAID sets (all 3 of them) are showing up as online, yet the drives are offline. No idea why. The drives are all powered, and are spinning, and plugged in.
    http://www.amcdoors.com/lorenzo/leftside3b.JPG
    when you click "Monkey Drive", nothing shows up in it. i don't remember if anything ever used to. if you click 'mount', nothing happens.
    http://www.amcdoors.com/lorenzo/leftside4.JPG
    http://www.amcdoors.com/lorenzo/leftside5.JPG
    this shows the exact same problem as the first RAID set.
    http://www.amcdoors.com/lorenzo/verifyRAIDset1.JPG
    If you try to Verify the RAID set, it shows that no repairs are necessary
    http://www.amcdoors.com/lorenzo/verifymonkey.JPG
    If you try to verify Monkey, you get a "Volume Needs Repair" error... but when you try to repair it, you get this:
    http://www.amcdoors.com/lorenzo/repairmonkey.JPG
    Really need help; this is a pretty critical problem. Someone that's familar with RAID solutions on MACs please help me out. We can't risk losing any data if at all possible.
    Thanks

  • IMac G3 OS 9.2.2 with DHCP problems

    I'm totally new to Macs, so I apologize in advance if I don't know the correct things to mention in this post. I just received two nearly identical iMac G3's (the only difference is one is 350MHz, the other is 400MHz) and wanted to get them onto my home network, which is currently dominated by Windows PC's. I reinstalled the OS on one of the iMacs since its hard drive was wiped before I got it. I used the gray "iMac Software Install" CD with OS 9.1 on it that came with the system. Install worked fine, and the system seems to check out.
    I hooked the computer up to an ethernet cable that is connected to my router at home. The link light on the router came on, and Apple's System Profiler says the ethernet connection is active and up. However, running through the Internet Connection Helper, I was unable to get DHCP working properly. I went into the TCP/IP control panel and here's what I have...
    Connect via: Ethernet
    Configure: Using DHCP Server
    DHCP Client ID: [this box is blank]
    IP Address: 169.254.84.226
    Subnet mask: 255.255.0.0
    Router Address: 169.254.84.226
    Name Server Address: [this box is blank]
    Implicit Search Path - Starting Domain name: [box is blank]
    Ending domain name: [box is blank]
    Search domains: [box is blank]
    Clearly my system is not getting a valid IP address from my router (a D-Link DI-524 with the latest firmware version, 3.20). I checked the system's name in the File Sharing control panel since some people suggested it may be the problem. The name is fine - it is "blue" for one of the iMac's and "indigo" for the other. Creative, aren't I? Anyway, something is going on where the link is up but no DHCP address is being assigned.
    I decided to hook the other Mac to the same cable. The exact same problem happens - only "169" addresses are assigned, not the "192" addresses that the router should be handing out. So I decided to test out the cable - it works fine with my Sony laptop. I connect it to the same cable and I'm online instantly. My router is set up to configure computers via DHCP, too, since release and renewal commands on the Sony laptop work just fine. I've rebooted, I've reinstalled the OS, I've updated to 9.2.1 and then to 9.2.2, and nothing seems to work. Both systems refuse to get DHCP addresses, but my Sony, on the exact same cable, works fine. I even changed the port that the ethernet cable connects to on the router - again, the iMac's fail to get an IP while other computers that I try with that cable and that port at a later time have no problem getting an IP.
    On a final note, when I set the IP configuration of one of the systems up manually and connect it to the router (forcing it to have an IP of 192.168.0.150, for example), I am able to then ping the iMac from a windows based PC on the network. Also, I am then able to ping the Windows PC from the Mac using a program that I found online to allow me to ping on a Mac. Strangely, I can't ping the router's IP (192.168.0.1) from the iMac even though traffic MUST be going through the router to get to the Windows PC from the Mac and vice versa when I do those pings. I have no problem pinging the router's IP from the Windows PC. It's a really strange situation and I just can't figure it out...
    If the cable didn't work with any computer, I'd blame that. If the router didn't assign IP's to my windows boxes, I'd blame the router. If I only had one Mac, I could theorize that it has some sort of problem with its ethernet port. If I couldn't ping in or out, I could also theorize that the link was broken somewhere in-between. But to have the exact same thing happening on 2 iMacs with virtually identical configurations and OS installations is really bothersome, considering all of the other networking equipment has been shown to work properly with the Windows machines. I have a feeling it is some setting that I don't know about on the Macs that must be changed or enabled / disabled, but I just don't know what it is. Any suggestions or help that anyone could provide would be greatly appreciated.
    iMac G3 400MHz   Mac OS 9.2.x  

    Access control lists aren't enabled on the router... like I said, it's strange that the pings are getting through (which an access control list would prevent). I reset the router to factory defaults and the problems I mentioned still remained.
    I tried out a different router and suddenly, without explanation, both Macs started working. I guess my D-Link router (DI-524) just doesn't like these iMacs running OS 9.2.2. They work fine with a Belkin router that a friend brought over, though - and that has me satisfied with their condition. Looks like I need to buy a new router, or otherwise contact D-Link to figure out what the problem is. I have a feeling just getting a new router will be easier, though. Thanks for the help. Hopefully someone else searching for help with these iMac models and a D-Link DI-524 router will find this information useful. Oh, and lastly, I have another D-Link DI-524 available... I connected the Macs to it, and again, they couldn't get IP addresses autoassigned via DHCP. This is definitely a compatibility issue between iMacs and this specific router model.

  • DHCP Problems on new SSID

    Hi all,
    I have an SSID where clients cannot get DHCP addresses. I have captured the following debug and from what I can see the WLC recieves the DHCP address from the DHCP server and then attempts to forward that to the Station but the station does not get it.
    Is my thinking correct? If so, what can cause the client not to recieve the DHCP offer packet from the WLC?
    Thanks
    Mario

    The WLC is sending the traffic properly.  The DHCP server is sending back a NAK to the Client REQUEST.  It's a bit odd because the client is making a Request to the same DHCP server, with the same transaction ID, with the same "offered" IP address.  Once the DHCP Server sends back an "ACK" instead of a "NAK", then you will be good.
    What is the device offering DHCP?  You might consider getting rid of DHCP-Proxy and simply bridging the traffic over.  Can you take a "wired" client and place them on VLAN 51 of that same switch and get an IP address?
