View 5 Replies View Related2 days ago, my laptop was connected to my router and working fine. But it then randomly disconnected and haven't been able to connect back since. I am using an ethernet cable to access the internet, and have tried many ways to try and resolve the issue but nothing is working.
I have a Dell L501x (Win 7 64-bit) with the Intel Centrino 1000 BGN wifi card. I have restarted the router and modem and disconnected all devices and tried reconnecting, but to no avail. I have tried updating the drivers, system restoring and using safe mode (with network) but nothing works. The modem and router are working fine as other devices connect and access the internet, it is just my laptop that cannot.
I am sure it is not a hardware issue as the card detects all the surrounding networks. The troubleshooter only says "An administrator profile failed to obtain an IP address from the DHCP server.
I have simple set-up in my network with 2 routers connected to each other, 2nd router is just kind of wireless access point and switch to extend cable sockets upstairs.I have DHCP reservation on the first router and it works perfectly.

View 7 Replies View RelatedI would like to share one problem with WLC 5508 . we added a new virtual interface on the WLC. One new SSID is associated with this interface.
We created a ACL for this interface to restrict the access via WIFI to certian services. It´s not correct that everything works fine because the change were not applied. [code]
The changes of the ACL are applied on the fly, but for reason we don´t know, the clients don´t get a DHCP IP-Address (after changing the ACL) until the Controller is rebooted.
I have an Avaya IP Phone for work. This has been tested at work and works as expected. After the IP Phone boots it's able to obtain an IP address from work. At home when I plug the IP phone into my DIR-655 router, it's unable to obtain an IP address. Other network devices are able to obtain an IP address, for example any computer or laptop. Also my wireless works with no issues expect for the IP phone. I've already done some searching and found other users with the same issue but I haven't been able to find a solution other than setting a static IP address. I'm curious why this relatively new router won't work with an IP phone. I've played with some of the router settings but it didn't make a difference. Any work around to get the DHCP to work? I'm running the latest firmware for my router: 1.35A Hardware Versions: A4.

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 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:

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.

View 4 Replies View RelatedI 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)?
I have a 4402 (version 7.0.235) working with 10 units of 1121 APs connected to it. The WLC is not configured to work in LAG mode. Physical portt #1 is connected to the Main Switch (trunk). I have 3 WLAN mapped to 3 Different VLAN and Everything (security and internal, external DHCP) is working swell...Now- I have connected Physical port #2 directly to an ADSL Router (giga port), Configured Port 2 as untaggedwith the proper IP details.I have configured this interface to receive DHCP from the ADSL Router and for some reason, Clients are not getting addresses.When I assign a Static address to my laptop I get internet access and all is nice. I tried configuring The WLC internal DHCP server (instead of the ADSL router) and that didn't work. It seems like a DHCP problem but I dont understand the source of the problem of think of the solution.When turning off the proxy settings I noticed that it worked. Is there anything to do with that? The problem was that after a while the other WLANs starting causing DHCP issues as well.
View 7 Replies View Related I have a Linksys WAP200 Wireless-G Access Point problem. It is SW version 2.0.4.0. I have it configured for a small network and the problem seems to be that it is not forwarding DHCP requests onto my DHCP server. I know that it is not a SSID or Key issue as when I give my devices static IP addresses, they communicate fine within my system. The only issue seems to be when the devices make DHCP client requests. I also know that the problem is not my DHCP server as it has the device's IP / mac addresses in its configuration file and other wired devices are able to communicate with it to get their IP address through DHCP.
I have seen that there was talk in some blogs about WAP200 no forwarding DHCP requests and I was hoping that updating the device to the latest release would have resolved the problems.

setup a DHCP server on a WLC 2504. I'll try to resume my configuration:
I have 2 networks: inside users (vlan 1) and external users (vlan)
My controller uses the port 1 to connect to the switch, which has a trunk with WLC.
I have two routers, one using vlan 1 (192.168.3.0/24) and one using vlan 10 (200.X.X.X). All ports to these routers are access ports on their respective vlans.
I have 2 SSID, one for inside, other to outside. Inside is working very well.
To the outside I created a DHCP escope and already set the IP of the management interface 192.168.3.119.
Managemente interface (vlan 1 inside): 192.168.3.119/24
Outside interface (vlan 10): 200.X.X.195 - Default gateway 200.X.X.X.193

I am trying to setup a guest vlan. I set up an interface for the guest vlan on my 4402 controller. I assigned the guest vlan interface an IP of 192.168.2.10 with a 24 bit subnet mask.
This vlan will go to my DMZ where there is no DHCP server so I need to setup the internal DHCP server. I created a new scope but I'm having trouble with what to put in the Network field for the DHCP scope. The pool addresses are 192.168.2.100-200. with a 24 bit subnet mask.
Every time I try to apply the configuration I get an "error in setting DHCP scope network and netmask".
I've tried using:
192.168.2.10
192.168.2.255
192.168.2.254
as entries for the Network setting but no go. The docs say to enter the IP address used by the management interface with subnet mask applied.
I was assuming they meant the interface for the guest vlan.
How to clear dhcp lease in WLC 6.0.199 from the IP leased from internal server?
View 1 Replies View RelatedI have two WAP321s in my office. The network they are on is a single VLAN (172.16.10.x). Both WAPs are setup with the same SSID, and I have setup Single Point Setup.
I am having a problem that was happening before I setup Single Point Setup, and it is still happening. Basically wireless will be up and running fine for part of the day. Then people throughout the office will begin to lose their connections to the DHCP server. They still retain the connection to the WAP, but can no longer access the network.
The only way I have been able to fix this issue is to reboot the WAP. As soon as it reboots the connections come back. At first I thought it was due to the number of connections (which is why we now have 2 WAPs), however we only have about 20-25 conncurrent connections.
I put in the second WAP to try to balance out the load but this does not seem to be working. Is there a setting I need to change on the WAPs to balance out the load?

View 3 Replies View RelatedWe have a 5508 controller authenticates with WPA2-enterprise to 3 possible AAA servers. Today I tried migrating our DHCP server from a Windows 2003 machine to Windows 2008 R2. Migration went smoothly and all wired clients could get IP's. Reservations intact, scopes intact, etc.. you name it. I though it was a great success.
Fast forward about an hour when people started coming into work for the day. Calls started coming in about their laptops not able to connect to the network. I double checked with a spare laptop in our IT department and also my iPhone. Same issue. Seems the only thing I changed today was the DHCP server (from 10.1.1.1 to 10.1.1.2).
After racking my head on it for awhile, I re-enabled the "old" dhcp server (10.1.1.1) and disabled it on the new (10.1.1.2). Instantly wireless clients were able to connect.
Am I missing some configuration step in the 5508 controller when moving DHCP servers? I do plan on running 2 DHCP servers (10.1.1.2 and 10.1.1.10) for redundancy once I get the primary one moved over and working correctly.
I want to decommision the older 2003 server. Its time to raise the domain functional level.
i have 5508 WLC and 1242 LAP . i 5508 connects to core switch and LAP connects to access switch, and there is L3 link from core swtich to access switch , so i have to use HREAP to let my WLC to control my APs.in my access switch i set ip helper-address to my WLC in the client vlam, then all the wireless clients cannot get ip address from the WLC.but if i set ip helper-address to another DHCP server , the wireless clients can get ip address .so i dont know why WLC cannot be the DHCP server of the wireless client?
View 3 Replies View RelatedFiOS gave me an Actiontec router that every other day is getting into a state where it refuses to give out IP addresses via DHCP. I have to reset the router to get it to work again.This seems ot have started in the last year, I assume due to some piece of equipment I added, or perhaps the VPN software or Windows 7 installed on my work laptop. I've not been able to figure out what is tripping up the Actiontec router, so I decided to try moving the DHCP function over the WRT610N that I have. I basically had the WRT610N setup without DHCP enabled, no NAT and no RIP, so it was basically just working as an access point. I left the Actiontec at 192.168.1.1 and assigned 192.168.1.2 to the WRT610N on the LAN side, while the WAN side is left disconnected.
I disabled DHCP on the Actiontec and enabled it on the WRT610N. I also set the DNS server to 192.168.1.1 so it would go to the Actiontec for name resolution. Using nslookup from a command prompt on a PC wireless connected to the WRT610N, I can see that names are indeed getting resolved. However, it looks like the WRT610N is setting itself up as a the gateway at 192.168.1.2. When trying to ping something out on the net, I get a message back saying that 192.168.1.2 is reporting the address as unreachable.
I assume this is because the WRT610N is handing out its own address (192.168.1.2) as the gateway. Is there anyway to get the WRT610N to hand out a different gateway address than itself? Optionally, is there a way to get the WRT610N to route requests coming to it over the Actiontec?I suppose I could just ditch the Actiontec altogether, but it seems a bit easier to use to setup port forwards and the like for various servers we have running. It also has a coax MoCA interface which I believe our FiOS set-top boxes use for their internet connectivity, so I don't want to lose that.
