I installed a wireless netopia usb adapter on my desktop, but I can't connect to my network, it says acquiring ip address, DHCP is enabled and started, but for some reason its not assigning this computer an ip address, I have two laptops also on my network and I don't have any problem connecting with them.

Last night the power either blinked or had a surge and I lost the internet on both of my computers. After restarting the Hughesnet modem and Netgear WNR3500L router, I now have internet service back on my laptop computer. However, I can't get it to work on my desktop. I have an HP Desktop running Windows XP (actually both computers are XP) using a Netgear Wireless-G USB 2.0 Adapter. Everything worked fine until today. Since then, it seems that the desktop sees the network, but can't connect to the internet. I've looked at a lot of forums and instructions and it sounds to me that the router will not assign the adapter an IP address. My wireless network connections have aegis protocol and tcp/ip selected, with obtain and ip address and dns server address automatically selected. I've uninstalled the adapter and reinstalled it and even done a system recovery on my computer in hopes to reset it, but nothing has worked. As you can see below I've tried most of the suggestions I've found online to no avail. I've also done the winsock and t something stack commands. I also don't know how to access my router b/c it's not connected to a computer. I could access it with my laptop, but I'm not sure how since it was setup with my desktop which required my entire desk to be physically moved at the time.

The Cisco 1921 router has two routed adapters. One is GE0/0 which I am using for my WAN interface. It is working properly. The 2nd interface is GE0/1 which is being used as my internal adapter. It is running NAT. When I attempt to reach the internet it fails while checking the exit interface. Here is the report.

That's a wonderful router on the paper! Really it has some problems with the wireless connection and the dhcp server. After 2 days of i must forced to reset the router because it refuse any wireless connection while the internet browsing on the other pc connected via ethernet ARJ45 is very slow.To complete the scenario the router doesn't allow any acces to his console page ..so what's the problem?
I try to change any channel for the wireless without no positive result.I bought it on amazon but if this situation will continue without any solution from tp-link i will forced to send it back with a totally negative feedback on the product.
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 a Windows 7 machine that is a client to an old SBS 2003 server. I don't use the server but once a month anymore because there is some old software that I need to keep on it. I also don't want to use the server for internet access anymore. I just use a wireless adapter on the client machine for internet connection. My problem is that I can either use my wireless adaptor for internet access or connect to my server. I can't do both at the same time (I get the "multiple networks red x") and no internet access.
View 4 Replies View RelatedI 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

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 14 Replies View RelatedIf 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.
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)?
We have a Comcast business class cable modem with a static IP address. There are two devices hardwired to it; a server and a Linksys WRT610N, The server is hardwired to it with port forwarding set for ports 21, 80 and 5900. It works perfectly and can be reached as intended by the outside world but not by our own network. Our Linksys WRT610N is hardwired to the modem. All computers on the wireless network see each other and can access the internet perfectly. So all seems well enough. BUT, no computer on our network can reach our server. Using the domain name or VNC connections from inside our system results in time outs and no connection.
View 12 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.
The e4200 1.0.03 DHCP server appears to be quite buggy. After configuring a static IP / reservation for a client which already had a dynamic IP from the pool, the e4200 continued to offer this client its pool IP. However, the DHCP client listing in the e4200 showed the client having the static IP even though it was still being offered that pool address.This may sound like user error, but I can assure you, it is not. I have had a very frustrating experience with this product, and rather than fool with tech support again, I ran `tcpdump -e -s1600 -n -vvvv -i eth0 port bootpc or port bootps` to absolutely rule out a mistake on my part, bug in the DHCP client, etc. I found that the client was always offered that old IP, even thought the e4200 status display showed the "new" static one, after doing a DHCPDISCOVER without requesting a specific IP. This condition persists across e4200 reboots even after having the client release its lease!I finally was able to resolve this by forcing the client to request the static IP from the e4200.This is unquestionably a bug in the DHCP server, and additionally, the user interface does not show the real state of the underlying DHCP leases held by clients which have static addresses / reservations. Troubleshooting this condition is well beyond the abilities of the average user.

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 alredy checked the DHCP Proxy in Advanced option.

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?
