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.
So I have this E1500 Router that worked fine for the past 5 months, then out of the blue, the wireless feature ceased to function... laptops were not being able to connect to the wireless, the router was also not broadcasting the SSID.So, here's what I have done so far:
1. Check the router software settings, all was good there.
2. Did a "hardware reset" pushing the red button. (now this solved the problem, BUT only for a day, when power is turned off for the night, the next day it's non-functional again. The cycle can be repeated daily, but its a pain to reset and set it up everyday)
3. Updated the Firmware, and this somehow solved the problem for 3 Days... and now it's back to non-functional, again out of the Blue.
Is the Router just busted and it's not remembering the settings?
Several days ago I had to change my router. The new one works OK except that I can't get the PC to link into the wireless while the SSID isn't being broadcast. Having read that it is a good idea not to broadcast the SSID for security reasons, I thought I would try it!
I am running Windows 7 home Premium and the router is a Draytek Vigor 2710 using WPA2. I can see the network when the SSID isn't being broadcast, it just refuses to connect to it. As soon as I switch on the SSID it connects like a dream.
i have 2 DIR 615 routers which both stop broadcasting SSIDS. Ive had only one connected at a time, thinking it was a bad router, but both behave the same way. Is this a known issue or something ? What happens is, after some time (it varies..sometimes 3hours..sometimes longer), the router stops broadcasting the ssid, and I can no longer connect any of my wireless devices to it. The hardwired connection does work (I have a server connected to it, and it appears to work).The only settings I have changed is my SSID name, and wpa2 password. I've set up one virtual server to port forward requests to the server. Thats it. Nothing complex or anything. And both routers behave the exact same way, meaing they stop broadcasting the SSID.
I have a "standart" settings of Cisco Aironet 1240AG with ENABLED broadcasting SSID, encryption is WPA2 (AES). I can see the wifi network (ssid) with windows system but with MAC OS 10.5 and MAC OS 10.7 also with iPhone the wifi is acting like hidden. But If I manually enter the wifi ssid and set the proper encryption the connection work normally. Also I have a separete windows partition on one MACbook and this windows 7 have no problem to see the SSID of my network. But If i Boot to the MAC OS the WIFI is "hidden" until the manually connection. (same problem on iphone, manuall connect with manually entered SSID is working well).
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]
We've had a Cisco 881W set up in one of our remote offices for a while and the wireless has been fine. Yesterday I got a call saying that the wireless was no longer working.
I went over and it's true, the SSID is no longer broadcasting. I reloaded the router but it's still the same. I tried to get access to the embedded ap and I get this
RTR#service-module wlan-ap 0 session % telnet connections not permitted from this terminal RTR#
Now I've not changed anything on the configuration since it went in and it was working before. Has the embedded ap died? The embedded ap is still showing as a component in show hardware.
I configured the device manually, not even using Express Setup or Express Security setup so... it is possible I missed something.Anyway, here's the problem. Although the SSID is configured as "AP1", this SSID does not appear among available networks on the client laptop.
The connection, configured in Group Policy for the client, should actually happen automatically, based on the SSID, but since the SSID is not being broadcast, that connection is failing as well.
The Aironet does appear among the available networks as "Other Network" and if I click on "connect" I am prompted to enter the SSID -> AP1
Although, unexplicably, an error message displays (Windows cannot connect to the network, or something to that effect), the laptop *does* connect once I close that window. Network access is complete and functional - I can ping other hosts, etc..
I'd post screenshots but not knowing what setting is missing or incorrect, I'd have to print dozens. So here's the sh run output of the AP obtained via telnet (just below). This is a test network so all information is "real" (nothing changed for privacy):
Note: I even changed the hostname to "AP1" (it's still LAB1 below) but that did not resolve the problem (did not think it would).
I am running the demo of the virtual WLC and have one 1142N AP connected to it. I have two WLAN's created and they are configured to broadcast their SSID's. However, when I look on my laptop or Android, I cannot see either of them. I checked the AP to see if it has the WLAN's on it and it does. I did this by going to Wireless -> Access Points -> Radios -> 802.11a/n AP Interfaces -> Details. Under Station Configuration Parameters -> Number of WLAN's, there are 2, which is correct. I had this demo running on VMware workstation and had some bridging issues with it and thought that was the issue. I now have it running on ESX5.1 and am still having this issue. I am at a loss as to what is causing this problem.
I have Build a 5508-HA Cluster (7.4.100.0) , hat to reboot this cluster due to Licens install.After the reboot atleast one of the SSIDs was not broadcasting anymore, even the checkbox was checked.
What did I do:
Installed the Licenses @ Freiday 12:00 @17:15 reload active WLC, wait till controller is up again (a few minutes pingable) @17:25 force failover to first controller. check a few SSIDs but not all, those who where check are ok. @monday 07:00 clients complaining not seeing the SSID (some where connected)
I have a linksys WRT54G that has been bugging out a lot. It stops broadcasting the SSID briefly and won't start again until it reboots. Annoying enough problem on it's own, but not my primary concern.My concern now is that when I tried to upgrade the firmware to the latest version (which I presume was causing the problems) the router now is essentiallyunresponsive. The upgrade was successful according to the control panel site, but ever since the required reboot as part of the upgrade process the router hasn't worked properly. 1) The power light blinks constantly rather than staying lit.2) When I plug directly into it sometimes I get access to local networks and other times I don't (limited connectivity). But I never get access to the internet if it's plugged into it as well.3) When I try to go to the control panel site (through the 192.168.1.1) the site wont loadGranted this router is old, but it was working fine other than dropping the broadcast every once in a while. It did need a firmware upgrade, but the upgrade seems to have been a bad choice
SSID is not being broadcast from an e3200. I split the wireless networks and assigned a new name for the 5Ghz band. The broadcast SSID button is enabled for both networks. (2.4 & 5). The idea is I want to stream video on the 5Ghz band. Nothing seems to see it though, TV other PCs, etc.
I changed the 5 GHZ SSID name using Cisco connect on my E3200 router as was expecting to see 2 available wireless networks on my laptop, but it seems that only the 2.4 GHZ is still broadcasting as it was before. When I connect to it with my laptop it shows it connecting with 802.11n, so I would think that my laptop would see the 5 GHz SSID if it was broadcasting. I am trying to take advantage of the dual band feature and connect the 5 GHZ to my blue ray player for real time video streaming.
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 have a WLC of 4402 and AP's of AIR-LAP1142N-E-K9 . Where am getting problem of that users are complaining that they cannot connect it some times and they used to get disconnected in between.
I have a D-Link DIR-652 router, and I can see that it is broadcasting but I cannot connect through my laptop, tablet, or phone. Sometimes it will let me connect but other times it says it is unable to. I can connect when I plug into the router through a cable. I'm doing that now, and I did an ipconfig/all in case to see that:
Windows IP Configuration Host Name . . . . . . . . . . . . : Kyle-PC Primary Dns Suffix . . . . . . . :
I'm trying to setup 2 VLAN's 1 for Native Traffic on my Corp network and another VLAN for Guest Wireless traffic. I have attached the Config from my Cisco AP1231 and my Cisco 3750. I have the AP plugged into port 24 on my switch. I seem to have the VLAN's working fine. I can get the AP1231 to broadcast both SSID's and the very first time i can connect everything seems to work fine. after i power down my switch and AP i cannot connect to either SSID. I get the message Not Connected.
I have Issues with Wifi radius Autentication.we uses cisco 1140AG access point, which is used in Standalone mode issue we face is,only Several Laptops not able to connect to wifi , But in all laptops SSID "wether" is broadcasting. signal strength is full. But it was not able to connect,If AP settings are wrong then all clients should not connect, since few clients connected it ruled out AP config errors,We uses ( WPA - Enterprise + tkip ) settings , clients mostly windows 7.Windows 7 settings also cannot be wrong, since it is globally pushed via GPO for same Wifi settings.i totally cant understand this scenario.when i checked the radius logs, i am not able to see any logs for the client since it is not associating, SSID is fully broadcasting in Laptop with full coverage. but just not connecting..
N900, WNDR4500, works fine as long as broadcasting SSID on 2.4, but if broadcasting SSID is turned off neither of wireless computers (windows 7 & 8) will reconnect.
I have my all my computers, printers setup with a wireless network with dsl modem connected to linksys wireless router. I just signed up with comcast with another wireless router. I do not want to reconfigure all the laptops and printers with the new comcast wireless SSID. Is there a way I can connect the linksys router with existing SSID with the comcast router and using the internet speed of comcast. (note. will disconnect service with dsl)
I have a WAP4410n which has been configured with a single SSID since implementation several weeks ago with no issues. I am now trying to add a second SSID and not having any success. Originally the second SSID was not being assigned a MAC address and thus not being broadcasted. After upgrading firmware to 2.0.4.2 I now see a MAC address associated with second SSID and it is being seen by clients, but they still cannot connect. I reset the AP to default settings and reconfigured from scratch but still no luck. I have two of these APs, the other one is still at FW rev 2.0.1.0 and has same issue (it does have MAC address associated with second SSID so I didn't bother upgrading firmware yet).
I have tried a few different authetication options, including disabling authentication, to no avail. Question - I do not see an IP address associated with the second SSID - is that the problem and if so, how do I fix that?
I would like to connect the AP541N to the RV220W and use the same SSID assigned to both throughout the office, for seemless client movement. I would like to keep the AP541N connected via the internet cable, as it will be on a switch which is on the same segment. The access point has many different configuration methods available, but the router appears to only have WDS as an option to connect the two devices. I would rather not use the WDS feature on the AP, as I want to utilize as much bandwidth available as possible, and I assume using that method I would need to remove the ethernet cable from the switch.
Is it as simple as configuring both devices with identical VLAN settings? I am preconfiguring the devices before installing them, as to minimize downtime, so would like to make sure the configuration is correct.
I have configure my AP with to SSID (11 & 12), but I cannot connect to 12. It authenticates, and while trying to acquire IP address from 12, it fails and connects me to 11 (if I have already saved the SSID connection).
The following is my AP status:Product/Model Number:AIR-AP1231G-A-K9 System Software Filename:c1200-k9w7-tar.123-8.JEE System Software Version:12.3(8)JEE Bootloader Version:12.3(2)JA4
The SSID 12 already have 4 clients connected, And I am tring to connect a 5th one (smart phone), but cannot connect to 12, instead coneected to 11. Also tried with a laptop, but cant get the IP address, and give Limited Connectivity error.
The router is a N Wireless Router. When I try to connect to my router through my phone the SSID appears as belkin.2lc and it won't connect but says authorizing then disconnected. The weird thing is that my laptop and all my roommates laptops and my Xbox can all see the routers real SSID and connect.just fine. I've tried restarting the router and my phone. I've also checked my router settings and made sure their is no MAC address enabled.
I had a DI-524 for years and I had no problem. My girlfriend wanted more range /speed for her netbook, and bought a DIR-655.
Had no problem with the netbook (acer One) and the Wii. But the Iphone 1st gen (cracked, but working good up to now) won't see any Wifi.
What to say. I have to read the F* manual, I know. But Geez. "The high end" said the guy at the store.
I should have search the web a bit more before buying because this subject (iphone connect problem) is a popular topic. [URL] won't change a thing. The Iphone don't see the wifi network.
i'm using win7 and linux mint in my laptop. when i'm on linux i 'm able to connect in a specific ssid with my b43 driver. when i switch back to windows(broadcom a/b/g) i can not connect to this ssid-there is a yellow mark with limited connection. what do you think? is this a driver problem with win7. or win 7 driver has ''less power'' than linux's?
actually, i have 2wire DSL Router and i am using SSID Broadcast Disable after disable i can't connect wireless to my extra device too for example my Blackberry. but i am using another computer with wireless but i can't connect blackberry and iphone i don't have more idea in wireless stetting what can i do?
I am having a LOT of trouble with an HP 6500A Plus wireless printer.It has been working wirelessly with my X2000 using WPA2 Personal encryption. (The WPA2 key has NOT been changed since it was working)It has recently stopped working and I cannot see why.All other devices (Wii, two iPads, 1 iPhone) all continue to work faultlesly.I have tried numerous times to reset the WPA2 security key on the HP Printer but each time it fails to connect to the X2000.It does recognize the SSID. But will not connect.I tried to turn on the LOG in the X2000 to see what information I could gather, but nothing get put into the Security Log. Maybe I am setting it up wrong, using "wireless" then "Log", then "enabled", then "view log", select "Security Log". attempt to connect from the HP Printer... twice, then refresh the log on the X2000, and NOTHING.
In the company we have two SSIDs for corporate and guest networks respectively when I try to connect to any of the SSIDs it doesn't happen until 5 retries. The only log I get that seems to be related to it is the following:
*Jun 11 11:48:09.062: %APF-1-DISCONECT_MOBILE_DUE_TO_WLAN_SW: apf_policy.c:541 Disconnecting mobile 00:23:32:73:d7:15 due to switch of WLANs from 1(femsawl) to 2(visitas)
Here it shows a switch between SSIDs but if you just turned on an apple device and try to associate for the first time to any of the SSIDs the scenario is the same, several tries to connect.I am running a 4402 wlc with 6.0.202.0 software version.
Has anyone come accross a problem whereby an SSID becomes unavailable when selecting a Radio Policy of '802.11g Only'? The SSID is configured identically accross multiple controllers, but only works on the WISM's. The same WLAN profile on a 5508 is unavailable unless I select a Radio Policy of 'All'.
All controllers (WISM's and 5508's are running 6.0.188.0)The WLAN profile is using MAC Filtering[WPA2][Auth(802.1X)] as the security policy.
