Cisco Wireless :: Connecting AIR-LAP1262N To WCS
Sep 13, 2012I believe I know the answer to this question already but I just wanted to make sure. Is it possible to connect a LAP access point directly to WCS without using a WLC? WCS is just for management and reporting and does not act as a WLC.

Sep 12, 2012I am trying to configure this newly purchased AP to be used for WiFi surveys, heatmaps, etc..
I cant seem to get to the web interface of the AP to make config changes, even though it is picking up an IP via DHCP and it is pingable.
Cisco Wireless :: AIR-LAP1262N-A-K9 Not Initiating Join Process?
Sep 11, 2012I foolishly put this 1262 into Bridge mode. The AP didn't accept that.
It had been joined to a 5508 running 7.2.110.0 and was running fine.
I've loaded on ap3g1-rcvk9w8-tar.124-23c.JA5.tar using the archive download-sw /overwrite /force-reload tftp://10.192.175.119//ap3g1-rcvk9w8-tar.124-23c.JA5.tar command.
When the AP reboots it has retained it's hostname from its CAPWAP days and indicates it is in DISCOVERY: %CAPWAP-5-CHANGED: CAPWAP changed state to DISCOVERY.
It gets a DHCP IP but never tries to find a controller. DNS on the subnet resolves CISCO-CAPWAP-CONTROLLER (& lwapp) to the 5508 mentioned above. I use this port for priming all my APs.
Are there other residual files in nvram: or flash: I need to remove? Is this thing now just a fancy paperweight?
Cisco Wireless :: AIR-LAP1262N-A-K9 802.11b And B/g Clients Frequent Disconnects?

Feb 22, 2012We have two Cisco 2960 TT-L switches. I'd like to reduce single points of failure and have dual servers for most tasks. For example, two firewall servers and two web servers. Should one server fail the other will act as a failover.I'd like to extend the redundancy to the switches, and am thinking of connecting one web server to one switch, and one to the other. In the event a switch failed a set of servers would still run, and be able to talk to each other.I'd like to run two VLANs, one for the LAN, and one of the WAN, and connect the two VLANs on each of the switches with the associated VLAN on the other switch.

Jun 9, 2013I have a lab network setup at my house with similar equipment to our office that I use for testing different features and functionality. Since I have had this installed (~ 2 years) I've had an intermittent but recurring problem with connectivity to various wireless devices that I have never been able to fully resolve.I have a 5508 Wireless controller with a handful of 3502i APs spread throughout my house. The controller is connected to a 3560X switch. And I have an ASA 5510 firewall as my Firewall/Internet Gateway. When I work from home I most often work from a desktop computer in my office and have a Windows RDP session to a laptop located in another room in my house on one of my monitors as a working space (I know this is weird but there is a good reason). This laptop is connected via WiFi at all times.Occasionally, I will lose connectivity to this laptop (or not be able to connect back to my desktop from it) and have to start an extended ping from the laptop to the desktop to re-establish connectivity. A while ago I performed some deeper analysis on what was happening and what I found is that when the connectivity breaks the problem is that the desktop is unable to resolve the MAC address of the laptop. It sends out ARP requests but never receives any reply back.
Why would the controller stop replying to ARP requests for the IP address of the laptop?If I log into the controller while this is happening it shows the laptop as a connected client, and has its IP address and MAC address listed fine in the clients section. In order to avoid getting up every time I need to reconnect, I normally hop to a system I control across one of my VPN tunnels via RDP, then connect BACK to the laptop and start the ping to re-establish connectivity back to my main desktop machine. This works because the firewalls ARP cache hasn't cleared yet. And then everything works fine again... unless I manually clear my ARP cache. Sometimes clearing the ARP cache will result in the exact same problem again and I will lose connection. Other times it seems to repopulate almost immediately and the connection doesn't drop.
A wireshark debug from the desktop reveals that ARP requests simply go out with no reply, confirming what is happening.As a note, I have set both the User Idle Timeout and the ARP timeout to 24 hours to try but this has not had any effect.This problem seems to go away and then come back. In fact, I havent been experiencing this issue for probably a couple months recently and then it just started again in the last few days which is why I am back to posting here. No changes to the network were made in the meantime that could account for this change in behavior. I am currently running version 7.2.111.3 but this behavior has persisted through at least four software upgrades so I don't think it's an issue with a specific version but I don't really know.I occasionally epxerience connectivity issues in my house to other devices as well that I use less often like a printer, network camera, apple tv so I now feel like these issues are likely all related.
Wireless Fail To Connect And Receive IP
Jan 12, 2012I have problems in the following scenario. I attached an image with a summary diagram of the network in question. The problem is that on the 3rd floor of the site users connect via wireless fail to connect and receive an IP. But they can not navigate. The second and first floor itself. As you see in the diagram are 3 routers, one per floor. The first is the only router that provides DHCP the other two routers are as simple Access Points.

View 4 Replies View RelatedCisco Wireless :: Set Up Fail Over Capability On Two Active WLC 5508
Mar 18, 2013for some reason some AP's are terminating the association to either one of the controllers for a short period of time. When this happens and the AP re-associates itself with either of the active controllers, it looses the information of what group it previously belonged; and it gets dropped in the default group, broadcasting every single SSID available.
What I would like to see happen is that if for some reason an AP terminates association, but restablishes it shortly; it can automatically go to the correct group.
Both WLC are running the same version and have the same amount of licenses, they can hold all the AP's one of the WLC came down. Config-wise they are identical except that the groups are named differently but ultimately configured the same. If that is an issue we can change it no problem since it's only the name.

Jun 22, 2011I have a point to point link of 9.27 km using 1410 bridges and AIR-ANT58G28SDA-N antennas as per the documentation that would be an easy to deploy link and it should work at 54 Mbps, eventhough it drops the link, it's so slow and the power measurments indicate -70 dbm (aprox) right under the antenna which is at 9 m height.
This is not the first time I have troubles with 1410 bridges, the other two times I had to change them for 1310 bridges. I wonder if it has to do with some configuration tunning like, external antena gain, link distance or anything else? By the wat this is ocurring in México don't know if that might be worth of taking into consideration in order to deploy a 1410 link.

Cisco AAA/Identity/Nac :: Wireless Clients Fail SSL / TLS Handshake And Reject ACS 5.2
Aug 29, 2011I have a problem where wireless clients at a remote site cannot successfully authenticate through their WLC to my ACS 5.2 (Linux on VM). I have three sites where this authentication is functioning properly; at my fourth site the wireless clients fail with a PEAP error: "12321 PEAP failed SSL/TLS handshake because the client rejected the ACS local-certificate". My wireless clients are Win7 using WPA2-Enterprise security type with AES encryption. The authentication method is set to Microsoft PEAP (EAP-MSCHAP v2) and the 'Validate server certificate' is not checked. My wireless access rules on ACS 5.2 are working well at three sites. My ACS 5.2 has a self-signed certificate that doesn't expire until August 2012. A laptop that can successfully authenticate at other sites cannot authenticate at the fourth site.
Phase one of the PEAP process is where the client authenticates the server certificate and the TLS tunnel is created so that in phase two user authentication credentials are sent through the TLS tunnel using EAP. My clients do not seem to be able to create the TLS tunnel because they reject the ACS local certificate; thus, user credentials are never passed and authentication fails. I have renewed the ACS local certificate and rebooted the ACS server but the problem persists. My WLAN on the WLC has its security policy set to [WPA + WPA2][Auth(802.1X)]. WPA uses TKIP and WPA2 uses AES; Auth Key Mgmt is set to 802.1X. The remote site where authentication fails is a different domain; the other three sites are the same domain.
I can see the failed authentication attempts in my ACS "Monitoring and Reports | Reports | Catalog | AAA Protocol | RADIUS Authentication" report. They all fail with the same PEAP error: 12321 PEAP failed SSL/TLS handshake because the client rejected the ACS local-certificate. The ACS local certificate works fine at three sites--just not at the fourth. Is my problem the certificate or is it an 802.1X client problem?

Linksys Wireless Router :: All 3 AE2500s Fail On A Single Computer?
Dec 4, 2012I purchased 3 AE2500s to connect 3 machines in my house.2 of the machines it works great. However on the 3rd machine, when I start browsing around (2.4Ghz or 5Ghz), things start going wonky and then the device basically loses connection, and the LED indicator starts flashing consistently indefinitely (with no connection).Removing and reconnecting the USB device will allow me to reconnect to my network and do stuff until it happens again. Speedtests on speedtest.net ALWAYS fail on upload test, I lose connection then.Streaming a movie across the network immediately causes this (exclamation mark on network icon) Regular browsing causes it also Checking event logs, I get the following error wlan extensibility module has stopped bcmihvsrv.dll The router is an E4200 I have tested all 3 AE2500s on this single machine, and they all do the same thing.Out of the 3 machines ONLY the one that doesn't work is Windows 7 32bit, the other 2 that do work are Windows 7 64bit Considering the event log is complaining about bcmihvsrv.dll, I know the 64bit version uses bcmihvsrv64.dll, could it be a bug in the 32bit drivers?I have attempted at trying different slots, uninstalling the drivers, removing and disabling any other network components in this single machine, lowering the power output in the advanced options, tried 2.4ghz and 5ghz, tried Wireless G only and then Wireless N only...

Cisco Wireless :: 1242 Can't Interrupt Boot Through Terminal
Apr 11, 2012We currently have 8 1242's and they all work fine, however we recently baught one 2nd hand one which was previously connected to a WLC, it lights up fine but it wont detect in IPSU even though the dhcp has assigned an IP to it. I would like to login through the web page to configure it but I am not able to do that either. It responds to ping fine though. So I no longer wont it be a LAP, so I tried to console in, to run flash_init etc. but when I try and give the <ESC> command (during the flash loader) it just carries on and ignores all input. I have used the correct settings Baud rate 9600, no parity, no flow control , databits 8, etc. but nothing happens it just goes through the boot and then asks me to press enter to input. i can then browse the directories and rename files. but I just cant get it to holt the loader so I can reset, I tried rename of config.txt and env_vars but that has't worked either. It keeps stating that it is looking for LWAPP/CAPWAP but unfortunately we don't have a WLC Is there another way I can reset it or is there some magic way in whic I can send the ESC command.

Cisco Wireless :: After Upgrade WLC 4402 Doesn't Boot
Jun 10, 2013I wanted to upgrade our three WLC 4402 from software version 5.0.148 to 6.0.202.0. The upgrade on the first controller was working. Unfortunately he lost all the local management users and it's MAC filters, but restoring this was not the problem. After upgrading the second controller.... the device does not boot anymore! The alarm led is RED and I don't know what to do. The only way to get connected to the controller is via the console port. There I can see a "parse error" but I don't know if that is the problem. Please look at the "log" attached. I'm not sure if the red alarm led was there before upgrading the controller software because the device is located to another place. I'm really concerned about upgrading the third controller because it's the most important wlc.
