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.

WRT120N on non-default network and DHCP problem

Hello,
I have setup the WRT120N on my network with an address like 192.168.3.X, the problem is that I cannot setup the DHCP server to serve on this network, it is fixed on the 192.168.1.X.
Is there a way to change this or I really need to setup my network around this router?
Thanks
Ivan

These settings are not possible. You cannot use the same IP subnet on the internet connection and the LAN. Routing happens based on IP addresses and subnet masks. 192.168.3.* addresses are on the WAN and the LAN side. How is the router supposed to know whether it should route an IP like 192.168.3.7 to the WAN side or the LAN side?
Actually the router should not allow you to set up this. Can you press Save settings with these settings and it is accepted? That would be a firmware bug. The LAN address should never be accepted with a internet address you have set.
Your settings suggest you don't want to use the WRT as router but as wireless access point and ethernet switch to extend your existing LAN. If that's the case, the correct setup would be to switch the internet connection type back to Automatic/DHCP. Leave the LAN IP address as it is or set it to 192.168.3.11 if you prefer that.
In addition, disable the DHCP server. (as you have it in your screen shot). The WRT cannot be a DHCP server when used as access point.
Save settings and then wire one of the numbered LAN ports of the WRT to your existing LAN. Don't use the internet port! Now the WRT is a simple wireless access point and ethernet switch. It does not do any routing, DHCP, or similar.

1242AG Association and DHCP problem

I am working on a 1242AG running 12.3(3G)JA1. It's setup with Radius using PEAP-MSCHAPv2. I'm having a problem with the AP assigning ip addresses to machines after user is authenticated. In the AP it shows the client as EAP-Associated but the wireless adapter has an APIPA address. what could be the problem? Many thanks!
-J.

Verify that the subnet the users are on, dhcp is working by assigning a port to that vlan and plugging in your laptop. If that works, then look at the configuration on the SSID to make sure the vlan info is correct and the switchport the ap is connected to is trunked correctly.

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.

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

%DOT11-7-AUTH_FAILED: Station c023.4921.2100 Authentication failed%Unknown DHCP problem.. No allocation possible

Hi All,
My wireless network system is consisting with 7.5 virtuall wireless controller and few 3600i APs.

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 ?

Snow Leopard and DNS problems

Hi
I read a lot about SL and DNS problems while accessing websites. It seems that you have to put your DNS server in system settings/network so that you don't get the error message "can't connect to the internet' in your browser window. My problem is that I change locations with my mac quite frequently (home, uni etc) so whenever I am a a new location I have to go to the network settings and manually put in the DNS server. Why do I have to do that with SL when it worked completely fine before the upgrade to SL?
Cheers
Martin

waschbaer22 wrote:
That is exactly what is happening. The problem with my DHCP server at home is that it doesn't submit the DNS address to the computer somehow. That's why I have to put it in manually each time I reconnect the MB at home after I had it at uni. Once back at uni I then have to go into the settings and delete my manually added home DNS server. Right after that the uni DNS server address appears automatically. So I guess that is just how SL now works and I have to live with it, right? However, why do we need a DNS server anyway to connect to the internet. I thought a DNS server just facilitates the connection to websites but I didn't know that it is crucial.
You should really try to figure out why your home router isn't providing you with a DNS server address and fix that. It could be a firmware issue, or it could be as simple as you have things set up so that one must manually be set up in the router, and one is not.
You are also misinformed as to DNS' importance.
DNS is the service that translates names - say "apple.com" - to the IP addresses - say "17.149.160.49" - that your machine needs to be able to connect to any site.
Without being able to resolve names to addresses, you have to manually specify numeric IP addresses for everything - effectively meaning you will be unable to use the Internet.

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:

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.

WET200 and DHCP

Hi there,
I noticed a few discussion about Cisco Wireless bridges not being able to pass DHCP requests from clients.
In my case I have a WET200 successfully associated with a Deliberant DLB2700 access point. When client computers are configured with static IP addresses they can browse the network, connect to e-mail etc. Problem starts when a computer will try to obtain the IP address via DHCP while connected to the wireless bridge. It simply doesn't work.
Is there a newer firmware or a secret settings which will allow me to make it working? I have a quite few of these WET200 units ...
Thanks in advance for any suggestions.

Hi Mr 2,
Please check the following link;
1. http://support.deliberant.com/forums/p/1069/4889.aspx#4889 does this sound familiar ?
But my thoughts are at this stage, sure look like there is a question hanging over the deliberant model number you mentioned, at least that what the deliberant forum might be suggesting.
2. But does a WET200 in place of the deliberant result in DHCP requests being dropped?
(Since you have multiple WET200, it would be interesting to peruse this approach for diagnostic reasons and to confirm this in your mind.)
But, if you can't do step 2 above, and are adventurous, maybe you can capture the DHCP server interaction.
I'm guessing your network may look like the following, excuse the rough network diagram;
PC---WET200~~~~~~~~~deliberant-------managed switch------------router
                                                                  |                |         |
                                                               HUB              |        |------DHCP Server
                                                                           mirror port
Beg borrow or steal a 'HUB' and they are hard to find these days, NOT a switch.
Or as an alternative, if connected to a managed switch, mirror the Ethernet switch port that leads to the deliberant AP to a PC running ethereal.
Using ethereal or similar application, just checkout the state of ARP and DHCP packets that egress in and out of the switch port that is connected to the deliberant AP. (I'm guess ARP is working otherwise you would not be getting anywhere from behind the WET200.)
But if you wish to post a ethereal trace, it would be fun to quickly check it out.
If you do this please don't capture megabytes, try to capture just a bit before and after a DHCP request.
The other option is to just keep doing what you are doing and statically define IP addresses.

AFP to a default host in AEBS (and other problems with F/W 7.1.x)

Hi all -
I have a AEBS version N connecting a workgroup of several Macbooks and a Mac Mini acting as a app server/file server. This workgroup is connecting to the internet via the AEBS running WPA.
Due to the network configutation, I have 1 publically routable IP address (200.13.99.x), which the Mini needs in order to allow "outsiders" access to a database app. The other laptops can share a NAT address for normal email, web browsing etc.
After several attempts, I found the best solution was to set the AEBS Ethernet WAN manually to the public IP address (200.13.99.x), and set connection sharing to share a public IP address. Then using DHCP and NAT options, I fix and specify the MAC address of the Mini (10.0.1.2), and get the AEBS to enable a default host to be the public IP address (200.13.99.x -> 10.0.1.2).
So far, so good. To recap, the AEBS has the public IP address (everthing else has a DHCP 10.0.1.x address). When outside users need to connect to the database on the Mini, they use the same public IP that the AEBS has. It works perfectly.
NOTE: This ONLY WORKS WITH FIRMWARE 7.0. F/W 7.1 & 7.1.1 FAIL and do not allow any connections in this configuration.
My question is this: How do I enable people to connect to the Mini and mount the filesystem remotely?
If someone goes to Finder, Go, Connect to Server, then input the public IP (200.13.99.x), they attempt to mount the AEBS (which does not have any disks). How do I disable disk sharing on the AEBS and forward all AFP (disk mount) requests to the Mini (acting as Default Host)? I have attempted to Port Map Personal File Sharing, but when attempting to mount 200.13.99.x I still see the AEBS.
The fallback plan is to buy an external disk for the AEBS, but it would be nice not to have that expense.
Any thoughts appreciated!
Regards,
Charles
===
Footnote: I have also seen a lack of stability in F/W 7.1.1. In addition to the above, I was having to restart the AEBS every week or so, and was also getting peridic connection problems to the Internet. F/W 7.0 seems fine. Hopefully these issues will be address in the next F/W release.

Hi Robby
I don't know if you solved your 'register now' problem concerning LE7 & LE8. I suspect the error your making is trying to open up each project in it's initial program - i.e. 7 or 8. The computer sees it differently (concerning Library settings etc) and your problem will be solved (hopefully) if you open up things in the right order :
1° Open Logic EX 8.
2° Then open the old project from LE 7. This should then open in your new system of LE8.
Of course if you wish to keep working on LE7 projects in LE7 then you'll have to change between each system as you go. You should remember that in terms of programs (with the same 'name/directory') that a computer works much like a tightly packed garage - if you wish to get out your old bike you'll have to move the new one first and vice versa!!
Normally you won't be asked to register again, BUT ... remember that you have to decide if you're going to save in 8 (and so keep working in that format) or not and I imagine if you've bought an update this is certainly your idea. Of course if you now decide to close LE8 and then start clicking on files in LE7 you'll be back at square one ..... register now etc. Please also remember that LE7 projects can work in LE8 but not the other way round, so once you've opened a LE7 project and made adjustments using LE8 you can't reuse 7 - I suggest you back up all your LE7 first on external/DVD support for later/backwards adjustments or reference.
Another small point to remember is that your computer will now be saving your project a second time in a LE8 format. So at some point you should remember that you'll be using valuable HD space twice over if you just convert and save in the new format - if you see what I mean?!

Radius, and DHCP DNS info

I have recently turned on the Radius server, and it seems to work fine, and has taken control of my Airport base station which is great. I only have one problem which is that the DHCP info provided by the server to the clients only seems to give one of the 2 DNS addresses that I have listed in the DHCP server info section. This is rather frustrating as it worked fine with WPA!
Any thoughts?

I just upgraded from a 2008 domain to 2012. I followed all the best practices, set up new 2012 DC and transferred all roles to it then removed the 2008 server. I just have the one DC at the moment and it's running both DNS and DHCP. Ever since we've had some odd DNS issues which usually require a reboot of the server to fix. Now at this point I'm digging through DNS and DHCP and seeing that a lot of client IP addresses are not matching up. DNS does not have the correct IP's for several clients. How can I fix dns?

WRVS4400N DHCP problems

Hello,
I have a new router (obvious) but it seems to have problems with DHCP and also problems when using N function, especially on the 40 MHz band.
First I thought the wireless NIC would be the problem but when I used another wireless NIC from a third party the same problems exists.
The only stable connection I get is if I give the wireless NIC a fixed ip address.
Router is an WRVS4400N version 1.1. The firmware has his newest version that I could find in the download section. Router has been reset to factory settings a few times.
The documentation is not very clear because it differs with the router functionality.
Router is configured to be used in Europe.
I hope someone can help me out or even point me to a newer version of this device.

I had the same issue that with the WRVS4400N 1.1.03.
After I reviewed these email threads and upload the 1.1.08 version, it is still the same, the problem cannot be resolved.
My scenario is:
1. DHCP does not assign any IP address to the wireless devices if there is no wired-LAN device connected to one of the LAN ports.
2. Once this wired-LAN device is connected to the router and got an IP address, the rest of the wireless devices got that too.
i.e. DHCP is not functioned properly. Can anyone advise how to resolve this problem? There is no new firmware update other than the 1.1.03 and 1.1.08(this is a special one and is not available on the web)
HELP!!

WRT1900ac and DHCP Static IP Reservations

I was trying to configure my WRT1900ac last night and had problems with DHCP reservations.
I wanted to manually add all the IP addresses prior to switching everything over to the router (to avoid any potential conflicts). I changed the router to 10.0.1.1 and wanted the DHCP to start assigning random clients at 10.0.1.100. I have static IP addresses grouped (i.e., 10.0.1.1-10.0.1.9 as network hardware, 10.0.1.10-10.0.1.19 as computers, 10.0.1.40-10.0.1.49 as TiVo equipment, etc.).
When I tried to manually enter everything, I was receiving an error message stating an invalid IP was entered. The reserved IP addresses should be outside the range of assigned IP's (or at least it is with most routers). I don't want random devices assigned IP's under 10.0.1.100 in case I need them for future reservations.

You need to ensure you are setting each device to Automatic Obtain IP addressing if your going to use Reserved IP address ON the router. Static isn't the same as Reserved. Static is set on devices while Reserved is set ON routers. Reserved IPs is preferred and recommended over Static for most devices. I recommend you try using the Default DHCP pool of 192.168 at first so you can check to see the process. It should appear in the device list then just select ADD to add it to the reservation on the router. Once you get the process down, then you could change the DHCP pool numbers however it's not recommended.

WRT54G V6 DHCP Problem

I have a WRT54G V6
I am use WPA 2 with AES
and useing MAC Filering
i have 1.02.2 7/02/2007 Firmware for the WRT54G V6
- i think it may be the Firmware

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.
What kind of Wireless MAC Filter are you using "Prevent" or "Permit Only"

Cable, BVI interface and dhcp

I have a router 2821 with two Internet links over "one" ethernet port. For this, I configured the interface GigabitEthernet0/1 in two subinterfaces with Vlans (interface GigabitEthernet0/1.998 and interface GigabitEthernet0/1.999). Betwen the router and the internet modens (ADSL and Cable) I have a Catalyst 2950T with the respective Vlans.
My problem is with the interface GigabitEthernet0/1.998 that is connected to cable modem (Motorola). This interface doesn´t receive IP address in the BVI interface via DHCP. If I place a workstation or the interface GigabitEthernet0/1 without Vlan configuration and switch the IP address is ok.
Bridging configuration because with the 'ip address dhcp' under interface GigabitEthernet0/1.998 doesn´t receive the ip address with the cable modem. If I place other dhcp server (Linux) with this configuration in the interface GigabitEthernet0/1.998 the IP address is ok. Bridging because cable modem.
With the BVI configuration, the dhcp client on the interface already received the IP, but after one or two days trying. In this midle time, the service provider doesn´t have allocated none IP and mac-address.
It has some suggestion, the problem is with the BVI interface or with the switch configuration (mac-address switch x mac-address router for the service provider)? What is the good design for this??

The Cable Service Provider is receiving the mac-address of interface fast
ethernet 0/19 of switch. Are there how the switch doesn´t send this information
and the SP receive de mac-address of router?
