Cisco Wireless :: AP 1231G Not Passing DHCP To Clients
May 27, 2012
My company AP 1231G is not passing the DHCP address to the client from the DHCP server, my config listed below basicly the AP is on its own VLAN 10.1.123.1 and the DHCP server is 10.1.10.2 -- trying to use iphelper to pass DHCP to clients and the AP is on static IP 10.1.123.2--

Here at HQ we have a 4402 WLC. At our remote sites we have 1231G APs running in autonomous mode. I upgraded one of the APs -- IOS 12.4(3g)JA -- to run LWAPP. Per release notes I've read upgraded 1231's do not support REAP/HREAP mode, consequently, it's running in LOCAL mode.
The AP is managed by the WLC. I created a WLAN for the remote site and assigned it to the MGMT interface; the remote site subnet doesn't exist in HQ. The DHCP server for the remote site is presently at that site; AP and DHCP server reside at the same place.
Clients authenticate successfully to the remote site AP, however, they are not getting DHCP addresses assigned. Does the DHCP server for the remote site have to reside in HQ since the AP is running in local mode? If so, where is that specified, on the MGMT interface config?

I have a Cisco RV220W running the latest firmware (currently 1.0.4.17), and I have noticed that after about a week of use, wireless clients can no longer acquire IP addresses via DHCP.
I have used Network Monitor on both the DHCP server, and the WiFi client, and can see that the server is receiving the requests and sending a reply, but the client never sees the response from the server. So far the only way to resolve this is to reboot the router.

I bought 3 of the Aironet 1231g access points and cannot get any clients to connect to them. I have tried everything from an Iphone, Droid2, Win 7 and XP laptops with built in wireless G cards. All say that they cannot connect to the wireless network. I have two setup currently, one on Vlan 1 that I have configured the way I want with WPA2 enterprise. The other one is just one I setup while playing around.

We have 12 - AP-1231G access points in our warehouse with 2 SSID's, both on different VLAN's. We would like to set one of the VLAN/SSID 's to use DHCP from a windows DHCP server.Is this possible to do with option 43 or is that only for lightweight AP's ? Sho ver: Cisco IOS Software, C1200 Software (C1200-K9W7-M), Version 12.3(8).

I have 2 1242AG APs setup with one SSID and no vlans configured. The APs are connected to a switch along with my DHCP server. Clients are able to connect to the SSID but are unable to get an IP from the server. Clients can plug into the switch and get an IP. If I configure a static IP on the wireless card, the client works fine.
Is there something I'm missing on the AP to allow DHCP requests to pass through? IPhelper?
Here is the AP info: AIR-AP1242AG-A-K9 12.4(21a)JA1

We've got a fairly plain-vanilla VPN configuration on a C3660 router running IOS 12.3(26) so that our employees can initiate VPN sessions to our office using their Windows or Linux workstations. In a typical windows L2TP VPN configuration, the default route is set to the VPN server, and no other routes are passed to the clients, which means that if the client disables "use default route" setting, even getting to the office network fails.
I know there's a way to do this, but I haven't found it yet. What I want to do is pass local routes to the client so that only those routes transit the VPN, and permit the clients to use their own default routes.

A little background on me: I do performance testing for a large corporation, so networking is like an old hat for me - but this has me spinning because it makes no logical sense to me.Here's the layout of my home network:CableModem(passthrough) -> WRT120N -> ENH200 (Access point) -> ENH200 (Client Bridge) -> Netgear N600Both the WRT120N and the Netgear N600 are providing wireless access to clients at both locations. N600 is set not to route or DHCP, and the WAN port isn't used.Initially the WRT120N wasn't in play because the cable modem was serving DHCP, but it wouldn't successfully send DHCP to most clients on the other side of the client bridge. So I installed the WRT120N (old, I know) and it was able to serve up DHCP to any and all systems... for a while. Now DHCP doesn't appear to be working fully again on the Netgear side of the bridge. One device registers in the WRT120N, the client list shows the mac as getting assigned an ID, but the device never actually pulls the address. Static works fine. Those that already have DHCP addresses work like a charm, so I know the link is stable. pingtest.net reports near perfection.

I have the bridge working but I have to assign a static IP address to devices connected to it. I can't get it to pick up an address from my DHCP server. Here's what I have:
Cisco ASA5505 (Firewall & DHCP server)
WAP54G - Access Point
WET610N - This Wireless Bridge
The ASA5505 successfully gives DHCP address to ALL wired and wireless computers. The WET610N has connectivity to the WAP54G. The status page indicates it's connected and I can get on the internet if I set a static address. However, once I configure my computer to automatically get an IP from DHCP, it just times-out and says limited or no connectivity. Again, when I set a static IP, I have connectivity to everything. I know the AP is working because I can get an address from my DHCP server (ASA5505) with my other laptops and even my cell phone. Why can't I get a DHCP address through this bridge (WET610N)?

We have setup a bridge between two of our offices using two WET200's in adhoc mode. Everything is connected fine and the signal strengh is good. All traffic pass's over the bridge correctly but DHCP requsts/replys seem to be failing to traverse the bridge. Our DHCP server is hosted on site A and the computers on site B fail to obtain thiers IP's from the dhcp over the bridge requiring us to use static IP's.Firmware is currently the latest.

We currently have a cisco 4402 with firmware version 6.0.182.0 and 4 WLANs currently running on it, we found the need to add an additional WLAN and after the configuration was completed and I tried to connect to it I found that we are not getting an address. If i connect a laptop to the VLAN I can get an IP and am able to browse. If i hard code an IP into a device and connect to the wireless i am able to connect and browse.

I am seeing a problem with our Cisco 300 switches. We use these switches as access switches, with a stacked 3750-G at the core, two 2960-S at the distribution layer, and about 10 300 Series switches at the access layer (10 port and 28 ports, all PoE).
We use Voice VLAN (VLAN 14) for our Mitel phones – there is a DHCP server on the Mitel system. Phones come up, get tagged VLAN 14 (LLDP), Traffic flows (including Broadcast for DHCP etc…). The system works, and has worked for months.
One day, suddenly, I find that all the Mitel phones on a particular access switch are not working. I look on the Mitel system and the lease on DHCP has expired, and the phone is stuck on renewing its DHCP IP address. I run port mirroring on the switch for VLAN 14 to see what is happening. The phones are stuck on DHCP discover, and I see the DHCP Discover broadcast packets on the switch but nothing else, no DHCP offer packets – hence the phone stuck at boot cycle.
I then do a port mirror from another access switch (that is currently working) – I can see the broadcast packets from the Mitel phones on the broken switch, but on this switch I can also see the DHCP offer packets from the Mitel system. I run two port mirrors simultaneous from the two switches (one working, one not) and I can see that the DHCP offer packets are not coming through to the broken switch. Panic ensues – I look at the distribution layer and there is no problem what so ever.
For some strange reason, the Cisco 300 28 port has stopped passing DHCP broadcast packets on a particular VLAN, even though they are being sent. I power cycle the switch – and hey presto, DHCP offer packets are coming through, and the phones get an IP address and boot properly.
Forward a couple of weeks later, and to today. I have another phone that is showing the same symptoms, luckily it is the only phone on this particular Cisco 300 28 port. The same issue is occurring as described above. I gather as much diagnostic information I can then reboot the switch – but still no joy. I then remember that this switch is not directly attached to the distribution layer and instead gets trunked to another Cisco 300 28 port. I give that a reboot and 5 minutes later, DHCP broadcast offers are passing and the phone boots.
I am listing this problem as not just a ‘one off’ now, and is recurring. It has happened to two of my 300 28 port switches.
All Switches running 1.1.2.0. No link to up time – first instance of the problem, switch was up for 14 days – second instance (another switch) uptime of 39 days LLDP is working fine on the switches, as is Voice-VLAN (Port is tagged and broadcasts out DHCP Discover which is seen by other devices throughout network) Nothing in the log file on the access switch Nothing on the Dist/Core regarding STP – Spanning tree set up is fine throughout.

Cisco Small Business Switch POE ESW-520-24P with a Wireless Access Point Cisco Aironet AP1141. Both the devices are upgraded to the latest firmware.
Connected to the ESW-520-24P is a Windows 2008 SBS 2011 with DCHP and Domain Controller. Along with the server I have a number of wired computers connected to the switch which do not have any issues and connect to the DHCP server without any problems.
When connecting two wireless devices to the AP1141, they get the IP address and DHCP from the server; but when connecting other devices apart the first two they will fail to connect to the DHCP server and do not get any IP Address. They manage to connect to the Wireless access point but they cannot contact the DHCP server.

I have two WAP4410N plugged into my Catylist 3560 switches.One of these switches is my Default Gateway for the LAN.The only way I can get a device to connect to the WAP4410N is by assigning it a static IP. Then it works perfectly.

I'm monkeying around with an 881-W. Clients can associate and authenticate to ssid 'test', but they cannot get a DHCP address. Clients plugged into f 0 - 3 get DHCP addresses just fine.
I've looked at a lot of different guides, ran debugs etc. When wifi clients make DHCP requests the server never gets them. So there must be some IRB thing going on.

I have new 2504 WLC + 1041LAP. I configured the first DHCP scope on WLC and the first WLAN. Then I set WLC DHCP server in WLAN properties and tried to connect to WLAN with wireless clients.
My wireless clients are able to authenticate on WLAN, but not able to get IPs from DHCP. The only lease that DHCP shows is for 1041LAP.
If I set permanent IPs on my wireless clients, they can connect and ping WLC.

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.

I have 19 locations, each with 1 or more LAP1142N AP's in FlexConnect mode, AP's are primed using CAPWAP to my 5508 WLC at the datacenter. The AP's join the WLC without issue every time. I have two WLAN's, one guest and one staff, the guest network is open and obtains DHCP from a WatchGuard XTM33 firewall at each of the remote locations. The staff side is WPA2/RADIUS and DHCP is assigned from the WLC. Each AP is assigned a static IP that is not in the DHCP scope. For example: DHCP scope on the branch firewall is 192.168.1.10-250 the AP will be assigned static IP of 192.168.1.1.. The AP's are connected to a HP procurve switch that has a untagged VLAN, the firewall is using the native vlan 1 and so is the AP.
I have been running this network for over a year and it has not had a single issue until the last two weeks. Nothing on the network has changed or has been upgraded.The issue I am seeing is that clients are no longer able to connect to the AP and do not get DHCP assigned to them. I am able to get it working, if I remove the static IP from the AP, the AP will reboot, join the controller, then begin working, users can connect and DHCP is assigned from the firewall as it should. However, If the AP then reboots, the AP will join back to the controller but no clients can connect nor do they get a DHCP address. So, I then reassign a static IP to the AP again and it reboots, connects to the controller and clients then can connect and get DHCP.i've found several posts on this topic, in fact the patch of unassigning or reassigning static IP is one that I found. I am also waiting on my SmartNet to start up and will be contacting Cisco support as well.

I'm setting up a Cisco Aironet 1141 (standalone mode, AP) to handle wireless traffic in the office. It gives out 2 mbssids, one of which authenticates domain users through a RADIUS server and places them in an appropriate VLAN (RADIUS options 64, 65, and 81). The other is a guest ssid that uses WPA-PSK and places users in the restricted guest VLAN. Physically, the AP is connected to a 3750 PoE Catalyst, to which RADIUS and DHCP servers are also connected. AP, SSIDs, RADIUS and EAP authentication all work. The configuration given below is a working configuration. People do get authenticated and do get placed in the appropriate vlan. The problem is that, once authenticated, the "Obtaining IP Address" phase on the client hangs and most clients timeout without getting an IP address. Given that the DHCP server is on the same switch and a test simple ASUS Wi-Fi IP gives out the same scenario (except the multiple VLAN) at the speed of light, I don't think that it's a problem with the network connections between clients and the DHCP server. After reading some topics here, I realized that probably other communication will be extremely slow, as well, but haven't tested that for sure. Clients are all non-Cisco - smartphones, notebooks, etc. Most of them are 802.11G, not N.

I have a (single) client (it is a cisco IOS router) behind a wireless workgroup bridge (cisco1242).The client's IP address is obtained via DHCP from the wired network.Now, when roaming occurs, the Client will never have knowledge about this event,and hence will not renew its IP address until lease expiers. This is not a problem of course when Layer 2 roam occurs, but with Layer 3
roam it will interrupt the traffic.
The cisco's IP Mobile implementation does have this issue addressed in DCCoA scenario: the WGB is configured to send an SNMP trap on its dotradio state change;the cisco mobile router is configured with snmp-server manager to process this trap and start DHCP renew on the Down/Up event. Unfortunately, this works in Mobile IP scenario only because I cannot make it work without the mobile router registered with a home agent.
how to force DHCP renew on a client (cisco IOS router) in such a situation - event scripting, SLA, or ...?

Is there a way to get the E4200 to NOT provide itself as a dns server to the DHCP clients? I have the unit set up to provide two dns servers to the clients, but the 4200 always provides itself as a third and it uses my cable providers dns servers. I am using a dns based filtering service to prevent certain material from being accessed within my network as the first two resolvers. So long as both or one of the provided servers is working it doesn't fall back to the unfiltered third, but I would prefer to remove it entirely.

The router always inserts its’ own address as the primary DNS server for the all DHCP clients even though you have set the DHCP server on the router to assign manual external addresses?
Oh I have a
WRT310n v2
firmware v2.0.01 build 004
Let me elaborate a little so I am clear what I am saying. On the router setup page go to the section that is labeled “DHCP server settings” enter 3 static DNS servers. Say 2 Google and one open dns.
8.8.8.8
8.8.4.4
208.67.222.222
Apply your settings.
Release your ip on your workstation, then renew it. And look at your DNS, the routers address is still the first entry.
DNS Servers . . . . . . . . . . . : 192.168.1.1
I suspect this was probably a design decision so that they could allow a user to open their web browser and type something neat like [URL]. Which for the average user is fine and dandy. If my ISP didn’t suck and try to redirect everything to cached copies I probably wouldn’t have noticed it. But since I end up using the router for DNS and it picks up DNS from my ISP I end up getting Akamai IP addresses, and they have problems with SSL certs…. So you get errors.
I know I can go set the DNS server settings on the workstations. But I really don’t want to do this on all of my devices as they are mobile and switch networks, and on some networks not using the local dns breaks things. Like on the corporate network.

I've got an E4200v1 running 1.0.04 firmware with guest access enabled. I'd like to find out who is logged in using the guest access. Is there a way to get a list of the DHCP clients on the guest network? I'm able to do this for the non-guest access via the WEB interface's Status->Local Network->DHCP Clients Table page. But I can't find a similar table for the guest network.

I'm trying to understand my options for assigning addresses to VPN clients on an ASA 5510. Under the ASDM, I have a field for DHCP servers, radio buttons: none, dhcp link, dhcp subnet, and field: client address pools. Cisco's VPN examples demonstrate setting up a client address pool, which I did, but the VPN client isn't assigned a gateway in the process so it can't connect to anything; I really don't understand the point of this. I'd like to create a DHCP pool on the ASA for VPN clients as this seems to be the standard configuration. However, I don't know where in the ASDM to configure this and how it's applied. The only DHCP options I found involved creating a DHCP server on an interface, which I don't want to do since VPN users aren't on a physical interface, right?

When on the management interface the clients can't get dhcp but the AP's can on the same vlan. I've tried enabling and disabling dhcp proxy, and using a remote dhcp server as well as the internal server. This same config works on the 4402 we're replacing with version 5.2.193 on it.

I've got a 2106 that I'm installing for a customer and having issues with it assigning DHCP to WiFI clients. What's odd is that this was working at one point at home during testing. Only difference at this point is LAN hardware at the customer location.

I don't have the specific version of code it's running, but I know it's 6.0. One of my local Cisco account engineers found some Cisco CSC bugs referencing this issue. One TAC cas even referenced stripping all security off the WiFi, connecting the client and then reimplementing the security again.

When I go into the Network Settings, and the end of the page I find a list named "Number of Dynamic DHCP clients: 7". As far as I know, I should only see 4, all 4 laptops; however, I see 2 UNKNOWN entries in this list, and one name "Macondo". Each of these entries have an option (a link) saying "Revoke" and other "Reserve". I am just wonder if these entries are intruders in my home network. What should I do? I am afraid to break my internet connection. By the way, I set up every single one of my family 4 laptops at home with a WPA-PSK using a very long key.

Some of these APs are using AIR-ANT 1728 (2.4 GHz omidirectional 5.2 dBi) and Mobile Mark OD9-240 (2-GHz omnidirectional 9 dBi) on the same access points. Some of my AP are PoE and some are using a power supply (at the AP) some are using both. Power level is set at 2 a radios are not enabled just the bg radios. I'm having issues: I need to tweak the APs (Power settings & Channel settings) so my clients (LXE VX6) can refresh faster.
