Cisco :: Cannot Ping APs Connected To WLC 2106
Jul 11, 2012
I have a problem with pinging APs that are connected to WLC 2106. We have a TRUNK with VLAN50, VLAN51 and VLAN71 (all tagged) connected to our WLC 2106. VLAN50 is our management network. We have configured bot management and AP-management interfaces on WLC with IP addresses from our management network and we have set both to VLAN 50. We have also configured static IP addresses on every AP, connected to WLC.
The problem is we cannot ping APs. This means that APs can’t connect to any other device on the management network and we would like to use RADIUS for WiFi client authentication.
How can we solve this problem? I guess if we configure VLAN50 as native untagged VLAN in our TRUN, this would work? Is there any way to configure this without using native VLAN?
We also have problem with IPv6 connectivity. We have configured DHCP and we are using 1.1.1.1 DHCP proxy and it works great for IPv4, but how can we configure DHCP proxy for IPv6 addresses? Our WiFi clients need to get also IPv6 addresses. I have enabled “IPv6 enabled” option on the WLC.

I'm setting up a 2106 controller with 3 APs.
When I connect the APs to a port on our 3550 switch, the AP gets an IP and associates with the 2106 controller. I can ping the AP from a wired PC and associate a wireless client to it. When I connect them to the PoE ports that are on the controller, it gets an IP and associates with the controller but, I cannot ping it from a wired PC or wireless client but, I can associate a wireless client to it.
The AP manager and Management interfaces, under PHYSICAL OPERATION are configured for port 1, which is the port that connects the Controller to the rest of the network. Since the whole network is using VLAN 1, I set the VLANs for the Management interface and AP interface to 0, untagged. I noticed when I set the AP manager interface to 1 I get the same results.

The issue i was having is when i connect to 192.168.50.* network i cannot seem to ping or connect to 192.168.51.2 (esxi host1) and 192.168.51.3 (esxi host2) and also free nas device i.e 192.168.52.2. i can only connect to these devices if i ping the 192. 168.50.1 from both the esxi hosts and also from free nas. Everything starts working if i ping from the esxihosts & Freenas device to 192.168.50.1.
f i connect to the hp procurve switch i can ping the hosts fine from the switch not when i connect to Draytek Router i.e 192.168.50.1 unless i run a ping from esxi hosts and free nas device then everything starts working.Here is my network setup for my ESXI home lab.
I have Draytek Vigor 2800 Router with ipaddress 192.168.50.1 (This Router is Downstairs and connected to DSL Line) and another Router with Firmware flushed with DD-WRT and IP address for this is 192.168.50.2. (this router is in upstairs labroom and is connected in Wireless Bridge Mode to Draytek Router Downstairs)
There is a HP Pro curve Switch 2610-24 with IPaddress of 192.168.50.3 and has VLAN's configured on this switch.The VLAN's are : VLAN10 is esxi vlan and ipaddress is 192.168.51.1 and vlan20 is storagevlan and ipaddress is 192.168.52.1 and vlan 30 is internet vlan and ipaddress is 192.168.50.3 (Switch Address).Port 24 is untagged to vlan 30 i.e internet vlan and connnected the port to dd-wrt router lan port. I have untagged ports 1 to 5 to vlan10 i.e esxivlan and connected esxi host's 1 & 2 to ports 1 and 2 respectively and connected freenas device i.e storage to port 6 which is untagged to vlan20 i.e storagevlan
IP Routing is enabled on the switch and ip route 0.0.0.0 0.0.0.0 192.168.50.2 and Default gateway on the switch is 192.168.50.1.
On the Draytek router i have configured a static route for 192.168.51.0/24 and Default Gateway is 192.168.50.3 and another static route 192.168.52.0/24 and default Gateway is 192.168.50.3

I've been stuck with a connection problem on my desktop for 6 months and nothing I do can fix it. My computer technician friends can't fix it either, so here's my last gasp attempt to get it online before I throw the machine out of the window.I'm using XP, don't recall ever having downloaded any Service Packs, and am trying to connect wirelessly to my home network here in France. Laptops and iPhones connect no problem. I don't think it's the wireless network card (which I bought nearly 5 years ago) as I had the same connection problem in my last apartment, with the same internet provider. I eventually borrowed an ethernet cable and managed to get it working wirelessly, but I have no idea how I did it.
The computer connects to the wireless network but I can't browse or ping. I've flushed dns, tried to input the ip manually, checked and unchecked LAN settings, checked and unchecked Internet Protocol TCP/IP, i've tried winsock, I've done the netsh reset and NOTHING worksI've checked the security settings, password and encryption a hundred times, I've disabled the firewall and today I've pulled out the recovery disks It didn't.Interestingly, the desktop has suddenly decided to go online once or twice (after I'd disabled Norton) but as soon as I shut down, I'm back to square one

I've configured a lot vpn server for 857/1800, etc. But this has never happened.I configured 881 as VPN server using CP.Shared key, local group and local user authetication with split route.Local pool 192.168.100.1-254? I have acl for telnet which allows local pool IPs.I have acl to deny local network to local pool IPs for NAT.I've deleted the whole settings and re-run the wizard. It's still the same thing. I can connect from the VPN Client, but no traffic going through. The problem to me is isakmp with DPD. But why it is dead? Why no response from the server? If it is an error, why connection has no problem.

I've got a netbook (Acer Aspire One) with XP SP3 on it. It connects to my wireless network (so it says), but it won't get onto the internet. I can ping 127.0.0.1, but it won't ping my router. When I do ipconfig /release > ipconfig /flushdns > ipconfig /renew, it hangs up on the renew portion telling me that the DHCP server timed out. The exact error message is:"An error occurred while renewing interface Wireless Network Connection 2 : unable to contact your DHCP server. Request has timed out.No operation can be performed on Local Area Connection while it has its media disconnected"I've checked the TCP/IP settings, it's set to automatically obtain and IP address and DNS servers. I've checked the DHCP service and that's running. The internet works when it's wired. I've used the "repair" function when right-clicking the wireless icon and it tells me it can't renew my IP address. I made an ipconfig /all when it was connected and this is what it came up with:
Host Name . . . . . . . . . . . . : Jencomputer
Primary Dns Suffix . . . . . . . :
Node Type . . . . . . . . . . . . : Unknown

I have a copper over ethernet connected to an adtran 908e connected to an ASA 5505 with a port 192.168.150.254 connected to the router on the Gigabitethernet 0/0
I can ping to internal and external ip addresses but when a device is connected through the wireless signal then the device cannot ping anything; what could be stopping the device from pinging any ip addresses internal and external?
I posted my current config for the router and ap:

I'm trying to configure a 2800 series router. .I'm consoled in and put a basic config on the router (see attached). After putting this basic config on, I plugged it into a small unmanaged switch, changed my laptop's IP and plugged it in the switch also. I can't ping the router from the laptop and vice versa. This is the second switch I've tried this with, so it must be.The first switch, I installed at location, connected a cisco cable to it and a local server, so i could remote in and finish configuration. In that scenario, I had plugged the switch into a managed switch and had the same result as I'm getting now--can't ping IP addresses (can't ping the switch's IP, not can it ping local IPs).

I have noticed that my virtual-access interface comes up but the line protocol of virtual-interface remains down as follows:
Virtual-Template100 x.x.x.x YES TFTP up down
Also The client PC picks up a random gateway of 10.10.10.1 which I never configured anywhere on the server.

I've setup a CISCO 871 which receives DHCP IP address on WAN interface Fa4 and DHCP-assigned static IP Address on virtual-ppp1. The static address is used for site-to-site VPN's, while I've planned the DHCP address for standard web access and CISCO VPN Client dial-out.
Internally, I've created 2 VLAN's, one for standard PC's with access to the remote sites via site-to-site and cisco client, and the other for a 'secured' area with only HTTP/S allowed out. [code]
Clients in the PCLAN should also be allowed to dial-out using CISCO VPN client to remote sites via the OUTSIDE interface. This is partially working because the client does log into a remote site, however I cannot ping or rdp remote stations once connected."ip inspect log drop-packets" does not reveal dropped packets when trying to ping or rdp.

A friend recently re-installed windows XP on their HP Laptop. They were connected wirelessly with a Linsys router (model wrt54g.1) and an RCA Cable Modem. The Cable ISP can ping the modem and gave me the IP address over the phone. I cannot ping the modem even when I take the router out of the loop. The network card (i1394) in the Laptop is functioning normally and I can see traffic on the modem (both the Cable Internet light and the PC activity light are flashing green) the ethernet port on the laptop is also flashing (amber). However I cannot reach the internet and cannot even ping the modem. The modem is brand new..

I have a netger router/moden connected to my phone line for broadband, an ethernet cable coming out of that to a netgear switch an then a cable going from the switch to fa4 on the 861. I can ping the netgear router from the 861, however, when I connect my PC to it, I am unable to ping let alone connect to the internet, the PC is getting an IP from the 861 and I can ping the fa4 interface from the pc. I just don't understand my I can not ping the broadband router, I even added a static route to the netgear with no luck.

we have the following setup for our network :
UserNetwork - ASA5550 - WAN Router 2911 - ISP Netowrk - Branch Routers 877s / 1941s
Since last week we started noticing this problem that the branch users started to complain of slow application response.. After verifying it with the ISP and middle network we noticed that if i ping from my machine (ie usernetwork) to the WAN Router interface (facing the ASA) , i get time outs.. which is strange cause this is directly connected to it via ethernet cable.

I was handed a Cisco 2106 WLC and 6 AIR-LAP1131AG-A-K9 acess points a few days ago and was told to get it working. My problem is i have never worked with cisco products, so i have been stumbling setting this up. Here is what I did get working Web interface into the 2106 WLC I flashed the 2106 from version 4.x to 7.0.116.0 I get green connected lights on numbers where AP are plugged in I configured the ap-manager area to settings of
Port Number=6
Vlan Identifier=0
IP Address=10.0.0.254
Netmask=255.255.248.0
Gateway=10.0.0.1
Primary DHCP Server=10.0.0.18
[code]....
I have logged into the console port on both the WLC and AP but i do not understand how to see reports or enable reports on either device to see what is wrong. I read that the AP can be set to lightweight or anon mode but i do not know how to check to see what mode they are currently in.

I've just installed a 2106 Controller at a remote site. The Controller is seen by the WCS at the main site so, connectivity is good and I'm able to login from the main site. I've configured the DHCP server which is at the Main site on the AP manager interface and the Manager interface and on the WLAN of the new controller but, APs are not getting addresses.

I bought a brand new 2106 WLC and a 1142AP. After going through the standard setup, the 1142 LAP was blinking red, yellow and green. I checked the logs and found the following message; [code]
I requested the latest IOS and Boot image for the controller from the supplier but he has provided only AIR-WLC2100-K9-7-0-220-0.aes, no equivalent boot image and has insisted that it is enough to upgrade the controller.
Is the AIR-WLC2100-K9-7-0-220-0.aes compatible with the 1142 LAP? And would I be able to upgrade the controller with only the AIR- WLC2100-K9-7-0-2 20-0.aes IOS and no equivalent boot image?

We recently purchased a bundle of 3 1042N AP's with a 2106 WLC. I am able to get the controller on the network and am able to manage it through the https web gui. I am now trying to add one of the AP's to the controller and am getting an infinite loop on the AP upon bootup. I tried looking up the solution but could not find a good article that pertained to the problem I was having. One thing I did notice is the time on the AP is way offset, but when I do a clock set to change it to the actual date it doesnt stick on the next reload.
Here is the output:

I hava installed a WLC 2106 with 4 1252 Aps. Some laptops has dual radio wireless card, but others has just 2.4 Ghz card.
I have one SSID with WPA2/AES and 802.11X authentication.
With the laptops with dual radio the speed is in 300 Mpbs, but when is single 2.4 radio the max speed is 70Mpbs
If i use a 1252 ap with autonomous IOS, SSID with WPA2-PSK/AES this laptops single in 2.4 works to 144 Mbps
is there a knowed issue about 802.11x in 2.4 Ghz or i need to make a different configuration to can work in 2.4 with a speed of 144 Mbps?

I got my final assignment from school, and my teacher asked me to configure 2 Access Points (1200 series) directly on a Wireless Controler (Cisco 2106). I can't ask my teacher for any questions, cause he doesn't know how to configure it also, THAT's why he's asking me to do it.I've learned a lot of things about the default static interfaces (the "management" and "ap_manager" interface), but i can't seem to fully understand how to configure it.I want to use the Internal DHCP server of the WLC. How I can get those 2 Access Points working on the WLC. I only seem to get DHCP issues.
This is what i've done:
- Leave the configuration of the "management" and the "ap_manager" default (172.16.1.30 and 172.16.1.30). Bound to port 1
- Made a new interface "AP1" with IP-Address 10.0.0.10 (/24), default gateway 10.0.0.1. Primary DHCP server: 172.167.1.30
- Made a new interface "AP2" with IP-Address 192.168.1.10 (/24), default gateway 192.168.1.1. Primary DHCP server: 172.167.1.30
- Made 2 DHCP scopes within the 192.168.1.0 and 10.0.0.0 networks.
For some reason, when i boot up both AP's, the won't get any DHCP address.

We have a 2106 that was configured by a former employee. No one left in the company is qualified to configure it. The wireless guest access used to work fine. We'd configure a guest user account. They would connect to the guest wireless, open a web browser and login. For some reason now there is no prompt for login. People can connect to it and get an IP address, but that's it. No login prompt or anything else from there.User Login Policies was set to 0 and I put it to 8. That didn't do anything. Under Web Auth > Web Login Page it's set to Internal (Default).
