Cisco Wireless :: 5500 WLAN / AIR-LAP1142N - Joining Access Points

Nov 1, 2012

Got a bit of a quandary with joining new access points to our 5500 series W LAN Controller. It looks like the LAP is initially able to see the W LAN controller, but after that things go sideways. The LAP is pulling a valid IP address from DHCP, and the W LAN Controller is able to ping it.
 
In the controller's AP Join Statistics we get this: 
Last AP Message Decryption Failure  
Last AP Connection Failure   -Timed out while waiting for ECHO repsonse from the AP
Last AP Disconnect Reason

Cisco Wireless :: AP LAP1142N Can't Join Controller - 4402

Apr 11, 2012

1) AP was originally running a standalone image.  I booted it into a so-called ROMMON or AP mode (ESC is the right key to make it boot into this mode).

I found a recovery image in its flash - c1140-rcvk9w8-mx. I made the AP boot from it by using "set" command and I see that it start booting using this recovery image. Here goes the question. Do all AP settings matter ? E.g. when I run "set" command from AP I see the following:
 
ap: set
?=
DEFAULT_ROUTER=10.0.0.1
Default_router=10.9.99.1
ENABLE_BREAK=yes

Cannot Connect To Public Wireless Access Points?

Apr 6, 2012

At home, I use my laptop to connect to my wireless router without any trouble.But at: public libraries, Starbucks, hotel rooms... any free public wifi? All attempts to connect meets with the same error: "unable to connect to network" (preceded by the system hanging for a lengthy amount of time). Windows advises me to unplug the router and plug it back in, which obviously isn't an option.It's annoying to troubleshoot, because I'm only having the problem at times where I have no wired access (hence: no way to get to forums like these and look for an answer, update drivers, whatever).

Cisco Wireless :: LAP1142N / WCS V.7.0.172 - Disconnects From WLAN Guest Access

Feb 7, 2012

We have a strange problem. We have a WCS v.7.0.172 that controls our two WLC v.7.0.116 and we have also two "Anchor Controller" WLC
v.7.0.116 for Guest Access.
 
We use the LAP1142N and every AP has two SSID's. One for internal data traffic and the other one for the guests.
 
Now the problem is, that even if we have internal and external user on the same AP, the guest users gets disconnected after a few time. Sometimes after 20 minutes, sometimes after 90 minutes...but the user is still working. It's really irregular.

Cisco Wireless :: AIR LAP1142N Access Point Configured And SSID Broadcasted

Mar 7, 2012

We have an  autonomous AIR-LAP1142N-E-K9 AP with software release version 12.4(25d)JA1. The access point is configured and an SSID is broadcasted. However when users are trying to connect to the AP, authentication seems to be accepted but users are not connected. I suspected the issue in DHCP but even on static IP the user is not connected.I dont believe any LAN issue is there cause I connected a PC to the same interface where the AP is connected and it took an IP from the required VLAN (1234) [code]

Cisco Wireless :: Clients Unable To Connect And Get DHCP LAP1142N AP

Feb 5, 2013

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.

Cisco :: Can't Connect To AIR-LAP1142N-E-K9 Unless SSID Is Broadcasting

Aug 2, 2011

I have a Cisco 5500 Series Wireless LAN Controller Model No. AIR-CT5508-K9 
 
I have HREAP groups in Boulder, CO,  Boston, MA, and Amsterdam, NL.
 
The LWAPPS act perfectly in the states (all AIR-LAP1142N-A-K9). The unit AIR-LAP1142N-E-K9 in Amsterdam will not allow any clients to attach unless the SSID broadcasting.  I don't want to broadcast SSID. I have used iPhones and Intel 5100 series wlan cards.  I don't get it. I have been working with Cisco for weeks.  We have even replaced the LWAPP.
 
I am getting this from the ASA in Amsterdam:
 
6    Aug 03 2011    20:20:22  PMTU-D packet 1485 bytes greater than effective mtu 1426, dest_addr=wificontroller, src_addr=LWAP, prot=UDP
 
I don't understand because the mtu on the outside interface is 1500  I guess "effective" is the key word which I missing here.

Cisco ASA5505 And Wireless Access Points

May 31, 2011

We have a Cisco ASA5505 here that provides DHCP and routing to all our devices in our network. We also have a few other switches and wireless access points connected directly to the back of the ASA5505.For the past year all the wireless network signals has been working fine however starting last month, none of the wireless access points (we have three WRT54G) would allow proper connection (dropping connection, slow internet).I thought this maybe all THREE wireless access points are toast/bricked. So i went out and bought brand new Netgear WN604 and even with the new WAP i'm having same connectivity issues (really slow internet).When hardwired directly to the switches we get BLAZING fast internet & connectivity, no issues.

I called CISCO TAC and they automatically said "our ASA5505 is fine, it has to be your wireless access points" not working properly. I explained to them that i also purchased two brand new access points and they are doing the samething now, how can that be?

Cisco Wireless :: WAP4410N Access Points Set Up

Apr 9, 2013

I've had some long standing issues that I've tried various things to fix.  I have two WAP4410N access points set up at a smaller sister company.  Wireless clients (laptops) are not receiving DHCP assigned IP addresses.  If I type in an IP manually, it works fine.The sister company has a point to point T-1 connection to our main building.  Our main building has the DHCP server.  The router on the sister company end is configured as the DHCP relay. 
 
I've upgraded the firmware three different times in the past to hopefully resolve the issue, but no luck.  Just today, on one of the WAP4410N's, I upgraded to the 2.0.6.1 firmware (backing up config, reset to factory default, upgraded firmware, reset factory default again, restored config).  After the first reset to factory defaults, the Access Point itself picked up a DHCP address from the server, and I verified this in the DHCP console on the server, so I know that the DHCP relay is working.  However, my laptop would not get a DHCP address when connecting wirelessly through that access point.  It is a Windows 7 Enterprise laptop.  I also could not get a DHCP IP with my iPhone connecting to wireless, to rule out specific issues with just a laptop.I have the DHCP lease times for the subnet that these WAP4410Ns are on set to 2 hours.
 
To put a cherry on top, there is one laptop that stays in a lab area at all times, connecting wirelessly, and it DOES get a DHCP IP address (I can see in the DHCP console that the lease for this laptop continually renews as needed).  I do remember on initial config when I couldn't get it to work, that I did a manual set up, gained connection, then switched it to DHCP...but that doesn't work for any other laptop.Why would the access points get DHCP address, but not anything connecting to the Access Points?

Cisco Wireless :: CDP On Access Points 3502 Aps

Mar 15, 2012

Using WISM with 7.0.220 and 1240 and 3502 APs. Just found that some of our 3502 AP didn't enbale their clean air and CDP when installed. This only happened on a few new APs.  But the area these APs where we seem to have had a few problems with PCs. The only PCs effected where Computer On Wheels (COWs), Dell 780 Desktop with a Cisco Wireless Card.

Using an interl wireless card and others in thes areas worked.Once I enabled the CDP and Clean Air, the COWs worked.My question is with the APs not having CDP enabled, could this affect the cisco wirelss card in the COWs?

Home Hub - Add Wireless Access Points?

Nov 10, 2011

BTW the halls are next to each other.The house and the 3 halls are in the vicinity however not attached together(i.e. wall to wall). The distance between the house and the first hall is approx 1 road width distance.ISP is Virgin and the internet was installed this year hence has the latest Virgin Home Hub.I am aware that i probably require 3 wireless access points (1 for each hall).The first wireless access point will need to be connected with a RJ-45 cable running from Home Hub. Can i connect the Wireless access points up together or do they all need to come from the ADSL hub?I am not sure what Wireless access points would be best and how to go about connecting this all up

Two Wireless Access Points With Two Routers?

Jul 5, 2012

I have New Pace 4111n Wireless Router that I got from AT&T and is setup on 1st floor, but its wireless range does not get me to 2nd floor. I also have the 2Wire wireless router from AT&T. In Addition, I have ethernet connection from level 1 to level 2 as well.

I was wondering if it is possible to have the Pace Wireless N router to work as modem and wireless access point, at the time use the 2Wire router to broadcast wireless and act as access point for 2nd floor.

IF its doable, how should the two be configured and connected.

Cisco Wireless :: Push Access Points To Second 5508 Via HA

Aug 9, 2012

I am having an issue here.  I have 2x 5508 that each have 100 AP license and a little under 200 access points.  Basically all of the access points are using DNS to connect to the primary controller that has the DNS entry.  Basically half of my access points need to be on the second controller and in order to do this I have been using the high availability mode of each access point to push them to the second controller IP address.It was working perfectly until now.  I have pushed 28 access points to the second controller and the last two I need to push at this location just keep resetting on the primary controller.  Neither controller is configured as master controller.

Cisco Wireless :: 5508 IP Scheme For Access Points

I have access points deployed across several buildings that each have a different IP scheme and their own T1 line. Is it possible to configure the 5508 controller to allow these access points to use the IP scheme assigned for that particular building or will dhcp always assign an IP address to the connecting client based on the IP scheme of the building that the controller resides in?

Cisco Wireless :: Access Points Which Are Not Registering With WLC 2500

May 1, 2013

We have a couple of Access Points which are not registering with WLC 2500. I followed-up on the two LAPs in the dorm.  They were cycling through red, amber, green, indicating they were trying to join the controller but could not.
 
Recently, we have changed our IP Schema for the Wireless Devices and I believe there is an IP Conflict between APs and WLC. Earlier APs were cofigured with Static IP Address assignment, thus they can't change their IP Address.
 
how to reset the Access Point? I know we can hard reset them by pressing the Mode button manually.
 
Is there another way via which this can be done witout removing the Access Points from their enclosures?

I have multiple cisco 1130ag access point at one of my clients villa. The issue I am facing is when moving throughout the buildingthe laptop and smartphones will not switch between AP’s unless it loses its connection with its existing AP then it will see the other AP that is closer and connect to it.
 
For example, I start at one end of the building where it connects to AP#1 , if I then slowly go to another section of the villa, it it will not switch over to AP#2 until the signal is lost from AP1

Cisco Switching/Routing :: 3550 Wireless Access Points

Feb 11, 2013

what I can do to accomplish my end goal of safe public wifi and configuration.I have 2 domain controllers (for redundancy) with a split scope for DHCP and they both serve DNS. I have VLAN 2 (management), VLAN 3 (Servers), VLAN 4 (Wired Access), VLAN 6 (Wireless Access) and VLAN 480 (Outside Wireless). I have setup INT VLANs for all of these on my main router (Cisco 3550) with the ip-helper address to the DC for all but the VLAN 480. All of this works great, and the scopes are setup just like the VLANs. (ie 192.168.2.0 (management) .3 (servers) etc.)I was wondering if there is a way to have VLAN 480 get DHCP from the cisco 3550 as a random address say, 172.16.0.0 255.255.248.0?
 
On a side note, I have seperate Wireless Access Points for the outside. (From a guy before me) I understand you can have a guest wireless setup on the newer Access Points, and trunk (cisco term) the 2 VLANs and seperate them out with Access Control Lists so they don't talk to each other, but I would rather just give the VLAN 480 it's own DHCP from the router.

Cisco AAA/Identity/Nac :: ACS 5.2 - Setup EAP-TLS Authentication For Wireless Access Points?

Cisco :: Missing Access Points On 2500 Wireless Controller?

We have a Cisco 2500 WLC with 136 APs. Recently, we discovered eight APs that were not listed on the Wireless > Access Points > All AP list. These APs were once working and connected, but now they are no longer in the All AP list. I located one of these APs and found the green LED blinking. I power cycled the AP and it came back online with a solid green LED and was then registered on the All AP list. The All AP list will only show the connected APs. I would like to know if there is a method to show the APs that were once connected and are no longer registered so we can better identify when an AP is not working?
