Cisco Wireless :: AP 1131 DHCP Server Connectivity Between IPad And AP
Jul 17, 2012
I configured DHCP pool on Cisco AP 1131, Laptop users are working fine and obtain IP address from AP 1131 DHCP Server, but IPad user is getting IP problem when he try to connect Cisco AP 1131.when i reboot the AP, IPad user getting IP address from 1131 AP dhcp server and access the network resource for the 2-3 hr after that IPad show "obtaining ip address from .....".

I have a static IP given to me by the service provider, and I need to make the Access point as a DHCP server to provide me IPs inside my LAN.I have created a DHCP pool in the AP. But do I have to NAT the public IP onto the private DHCP range ? This setup is possible.
Until a couple of days ago I was able to connect to the internet wirelessly on both my laptop as well as my desktop. However, that has changed for the desktop, now I am unable to access the internet on it. It says that it can detect the signal. When I tried to renew the ip it responded with "An error occurred while renewing interface Wireless Network Connection : unable to contact your DHCP server. Request has timed out." [code]
I have a Gateway 818gm desktop pc and the wifi stopped working after I reformated the hard drive. I can not figure out where the wifi card is in this PC.
We just moved and had our internet service connected at the new house using the same service provider, wireless router and network we had at the old house. My PC can access the internet fine, but my wife's iPad cannot.
We are implementing a new corporate wireless network with Cisco 5508 WLC's and C3602I LWAP's. We are not running any RADIUS or EAP at the moment and are starting with WPA2 w/ AES with a pre-shared key to begin piloting. The issue we are having is iOS based devices (iPhone/iPad) do not seem to want to connect. We just get a could not join wireless network messages. We have had success with several Windows based laptops, my MacBook connects, as well as several different Android devices.Looking at the logs on the WLC I see these entries which correspond to the MAC address of my iPhone.

We are experiencing problems with Apple Ipads on a large scale network that we install and maintain, the Ipads seem to join the network with no problems (bit slower than laptops etc) but will then disconnect for no apparent reason at random intervals. We have ran laptops on the same AP's and in the same area and no similar probems occurred, we are using IOS Cisco 1041's and 1042's, we have seen one of the Ipads's sitting quite happily on a 1042 2,4ghz radio and then it disconnected and went to the 5ghz radio. We are getting similar disconnects on the single radio 1041.
i am getting internet from someone by a LAN cable. the lan Cable is connected to my LAN Card (RJ45).i bought a IPAD. and i want to browse using IPAD. IPAD needs Wifi connectivity. can i convert this existing setting to browse internet from my IPAD?
My iphone wireless connectivity to my Linksys router that I have put up with for a year, but as I now have the same issue with my ipad I've decided enough is enough.The issue is that they both connect OK to the router and therefore to the internet, but after a short period of time (minutes) whilst it appears that they are still connected to the router the connection seems to completely hang. At that point I have to go into settings on the iphone/ipad and turn off the wireless connection and turn it on again. This then allows connectivity and internet activity for 5-10 (15-20) minutes before it hangs again.I have no problems with connecting to any other router from the iphone and ipad. And I also have no problems with my PC's connecting to the Linksys router.
I have an EA2700 running latest firmware 1.1.38.138827. It is using Cisco Connect Cloud. I am unable to access the DHCP Reservations link under Connectivity/ Local Network. When I click on it, nothing happens. I've tried multiple browsers including IE 10 (Windows 8 RTM), Firefox 15, and Chrome 21. I also tried on a Windows 7 machine with IE 9 and the link doesn't work on that either except that it shows a box that says Invalid Character when I click on the DHCP Reservations link. I see no invalid characters on the screen. Any workaround other than downgrading the firmware or assigning static IPs on individual PCs?Also, on an unrelated note, where is the Dynanic DNS configuration on the Cisco Connect Cloud?
i have windows 2008 R2 as CA server. and i also have 2911 router as remote vpn server. Everything works fine for desktops computers and leptops. Users automatically enroll certificates on Microsoft CA server and get connected to vpn. But problem is with ipads. When i try to connect from ipad error massage deslpays "Could not validate the server certificate" and i also get chis error massage from router "CRYPTO-4-IKMP_BAD_MESSAGE: IKE message from x.x.x.x failed its sanity check or is malformed"
With ipads built in vpn client i can see the installed certificate and use it but with anyconnect client no certificates are displayed.
win 2003 dhcp server. when I leave dhcp services OFF i can ping the server fine. once i turn ON dhcp services the connecting drops in and out.. what is going on here? My users are unable to get a steady connection to the dhcp server.
I have a 2504 WLC and 1042 ap's. Everything worked great in my test enviroment (of course). Now when I want to deploy the wireless, the ap's are not getting and ip for the windows dhcp server.
I have option 43 configured in dhcp, sub option 241>ip address of the controller I have my A record in dns, cisco-capwap-controller.

I have converted ap 1131 from autonomous to lwapp successfully by using upgrade utility tool but the AP does not join the WLC 2106. I can see it as a neighbor on the switch with no IP address.
I am able to obtain IP addresses through the DHCP server for my clients and I am able to browse internet on the server 2k8.Server 2008 - Share Internet through DHCP server
I'm seeing some weird behavior trying to connect my Windows XP SP3 desktop via a USB wireless to my Windows network via Linksys WRT120N Router. It is unable to connect with DHCP. "Limited or No Connectivity" is shown on the network icon and no internet connectivity is present. When i manually assign a static IP, i am able to get connectivity to browse the internet, and I am able to ping the other computers in my network, but I am unable to view the windows workgroup. I am able to manually map network drives, but those drop continually. There seems to be no rhyme or reason to the connectivity and the dropping while I am using the static IP. DHCP does not work at all. I'm just trying to get this computer connected to the windows workgroup so that I can map network drives and printers once and for all. Right now the rest of the network (ethernet cabled to router) works fine. I'm thinking it may be something in the routers wireless config, as I am having the same issues (DHCP not working at all, static IP working but constantly dropping) with a Mac laptop.
I have Internal DHCP Server configured on the Cisco WLC 5508 and all is working fine. DHCP Range is 192.168.1.100 to 192.168.1.245. Now I created another SSID but I want clients connecting to this SSID get specific IP's or from a specific range. WLC has no option to bind a DHCP pool to a specific IP so what I did I checked the option to "Override DHCP" and added the IP of my firewall WLC is connected to and setup a DHCP Pool on that firewall as 192.168.1.89 to 192.168.1.94 (192.168.1.88/29).
Client can connect to the second SSID but can't grab and IP address, what am I missing ?
Recently I came across a wireless design whcih I ws not able to understand.The design is:
1. Two wireless LAN Controllers 5508, each with 25 AP license. AP load (5APs per Contorller) shared between the WLCs and congured with Backup Controller option.
2. The design has a Data Center Switch 3560x series, on which the two WLCs, Cisco Prime Infrastructure and Cisco MSE were connected. I've attached the design here.
3. The Data Center Switch is configured with DHCP pool for the wireless clients. The IP Address of the Data Center Switch is : 10.xx.xx.2 and Default Gateway is: 10.xx.xx.1
4. On the WLC, the Management Interface is configured with the IP Address: 10.xx.xx.21 for Controller 1 adnd 10.xx.xx.22 for Controller 2. But, their DHCP Server is configured with IP Address: 10.xx.xx.1 but not with 10.xx.xx.2 .
This means, all the DHCP requests are pointing towards the Gateway of the Data Center Switch.Is this the correct configuration?I have seen the Wireless Clients getting the IPs allocated from the DHCP Pool, even though the Management Interface's DHCP server configured with Gateway IP address 10.xx.xx.1 .
The DHCP configuration for the Data Center Switch is:
ip dhcp pool xxxxxx network 10.164.220.0 255.255.254.0 default-router 10.164.220.1
The Management Interface configuration on the WLC is:
Interface Configuration Interface Name................................... management MAC Address...................................... 2c:54:2d:72:b5:40 IP Address....................................... 10.164.220.21 IP Netmask....................................... 255.255.254.0 IP Gateway....................................... 10.164.220.1 External NAT IP State............................ Disabled
I have successfully implemented wireless guest access using 4402 WLC as the Anchor and 5508 as Foreign. The Anchor controller also provides dhcp services to guest clients. The 5508 is LAGged and there is no issue with the guests traffic separated from corporate. At a remote site, there is a 4402 WLC using LAG and also acting as a Foreign controller. But when a client connects to the guest WLAN, it obtains a corporate dhcp address instead of the dhcp address assigned from the Anchor controller. The guest WLAN setting is the same as with the 5508 controller i.e. DHCP server override is ticked and the management IP address of the Anchor controller is specfied. Also DHCP Addr required is ticked. Why the 4400 controller is not forwarding dhcp requests to the anchor controller and instead sending to the corporate dhcp server.
Is it problem with iPads or LAP1141n?WLC 4404 and many 1142 and 1141, so other devices laptops, iphones, androind phone works as well.But iPad authorized, but can't get an ip address from dhcp server (dhcp not local on wlc, on windows machine) with coverage lap1141, but it get ip with coverage lap1142, and when i got it i roaming to lap1141 and it stays, if i off/on iPads can't get it again from lap1141.
If I set a primary DHCP server in the interface configuration, or if I override DHCP in the WLAN Configuration.Which interface does the WLC use to try and connect to the DHCP on behalf of the wireless clients?IFA) The dhcp server is not on any of the configured subnets.B) The DHCP server is on a different interface's subnet.
I am hoping to get your feedback around the dhcp issues I am facing with Two Centrally Switched Wireless LANs. The setup is as follows:
- I have a WLC 5508 which has been configured with 4 SSIDs, out of which 2 are using Central Authentication and Switching. - I have an LWAP connected to the WLC in HREAP mode. - WLC is configured as the DHCP server for clients connecting to the SSID 'Guest'. For the rest, I am using external dhcp server. - Only one scope for Guest Interface is setup on the WLC.
Problems: 1. As far as I know, for WLC to act as internal dhcp server, it is mandatory to have the proxy enabled, but the Clients connecting to SSID 'Internet' are unable to get an ip address from the external dhcp server, if dhcp proxy is enabled on the WLC. If i disable the proxy, it all works fine. 2. DHCP does not release the ip addresses assigned to clients even after they are logged out. 3. If a machine which was earlier connected to 'Guest' SSID connects to the 'Internet' SSID, it requests the same ip it was assigned by the WLC which it was assigned under 'Guest', but gets tagged with the V LAN configured on the management interface.

A client wants us to use the internal DHCP server on a 5508 instead of Windows DHCP. They will have 15 APs initially and upto 25 later. The docs on the 7.2 WLC make it sound like this is discouraged: Internal DHCP Server.
The controllers contain an internal DHCP server. This server is typically used in branch offices that do not already have a DHCP server. The wireless network generally contains 10 access points or fewer, with the access points on the same IP subnet as the controller.
In this case, the APs will not be in the same subnet as the Managment Internet.Is it a mistake to use the internal DHCP with upto 25 APs (3 WLANs)?
We're in the process of upgrading our Wireless AP's from autonomus to LWAP. We're doing the upgrades remotely (we have 100's of sites to do, and it's not possible to be there to console on to each one), using a local computer to upgrade them to LWAP's with the Cisco Upgrade Tool.Having some inconsistent bugs pop up though from time to time.The most common one is that it basically buggers up the IP address after applying the recovery firmware image. It's supposed to keep the IP it had according to the IPFile.txt (for example 172.25.25.4), but it does something very weird... it keeps the last two octets (so 25.4 from the e.g) but replaces the first two octets with a 192.168 address. So the final address in this example after the UpgradeTool has done its work, is 192.168.25.4 - which is compeltely wrong.
This causes it to be unable to talk to the WLC (obviously, with bogus IP information it will struggle), and gives us big problems in that it wont ever come up unless someone can console to the AP and fix it. We can usually resolve the issue by munging about on the switch - switching the port it's connected to between access and trunk and doing some shut/noshut cycles seems to do the trick mostly.
I recently had to deploy about 4 cisco 1131 AP's to one of our branch location. When configuring them on the controller, i needed to put them in HREAP mode. As soon as i do that and the AP needs to reboot, it will continue to reboot in a loop and indicate the following:
Unexpected exception to CPUvector 1100, PC = 5A9048 -Traceback= 0x5A9048 0x48A8A0 0x4361FC 0x42E078 0x44880C 0x42A280 0x42AA68 0x18A990
I have an AP(1131) that keeps disassociating from the controller. It stays alive for about 10 mins then it doens't work anymore. I tired changing the AP but that didn't make a difference. I also tried changing the port on your 500 POE switch. My last effort to fix it was to put the AP on a 3550 switch with a power injector. Still no luck.
I don't understand why its doing this. I am able to connected to it and surf the internet for about 10 mins. After that It leaves the controller and just cycles through different colors.
I have some questions about this AP and it's IOS. I have some AP's 1131 and they have IOS 12.34(3g) JA I'm working with a 4402 WLC I'm going to change this WLC for one 5508 but this WLC has a different version software it has 7.2.103. My questions is I need to do any upgrade to my AP's IOS for join to the new WLC ?
I found a compatibility Matrix, in this document I guess i nedd to do some upgrade: URLs
The WGB can be any autonomous access point that supports the workgroup bridge mode and is running Cisco IOS Release 12.4(3g)JA or later releases (on 32-MB access points) or Cisco IOS Release 12.3(8)JEB or later releases (on 16-MB access points). These access points include the AP1120, AP1121, AP1130, AP1231, AP1240, and AP1310. Cisco IOS releases prior to 12.4(3g)JA and 12.3(8)JEB are not supported.
