Cisco Wireless :: Devices Hiding Behind A 1242 Bridge
Jun 10, 2012
At intermittent times, we will have a single device start to "hide" behind a 1242 bridge.In the past, my team would reload or reboot the bridge, and everything would come back up.But the 90 seconds of lost data were causing problems.
I found the the WB was always available.So I would ping the hidden device from the WB, and it would ping.Next, I showed the ARP table, and got the MAC address of the hidden device.Then, I would start a ping from my PC, and leave it running. Constant "Destination Unreachables" from the router.Next, I showed the bridging table for F0, and sometimes the device would be there, sometimes not. I would add a forwarding bridging entry manualy, and exit conf.
Showing the briding table would show the device, with a "P"ermanent age, but still no pinging.Finally, I would remove the forwarding briding entry, and pings would start within a couple of seconds.During these periods, outbound UDP packets will continue to be forwarded from the PC.So, my managers want to convert everything to UDP, which is a potential disaster in my opinion.

Is it possible to make a bridge using a 1242 and a 1310? I have been able to get them to associate together and it appears it will function as a bridge. I have the 12(4) 253 JA IOS for both devices. I would like to use the g antenna on the 1242 for the bridge and the a antenna for wireless clients. The configuration on the web management appears to support bridge root and non root for both devices.
I have Eight AIR-AP1242AG-E-K9's accross our site that have 2 SSID's and 2 VLAN's that work well, I want to link one of the AIR-AP1242AG-E-K9 to another one using 5ghz patch antennas across a 50 metre gap, but I am puzzled on how to do this, as to create a root bridge and a non route bridge link I need to put the infrastucture SSID on and this must be on VLAN1 but I want the traffic from both VLANs to pass over this link. I just want to ensure the config will work as I need to go into a cherry picker to get to the non-root-bridge.
I try to change the AP mode of my LWAPP 1242 from local to bridge mode. But when the AP reboots it never associates with the controller, i have to reset it manually.I have the same issue with a LWAPP 1142.I tried to modify the AP mode configuration through the controller CLI but it's the same behaviour, AP never associates.Is there any particular parameter or configuration to perform before changing AP mode?
What kind of hardware are people using for mobile bridges? I have not had good luck with Cisco 1242's in bridge mode with mobile-client enabled. The only reason we're using the Cisco access point over standard industrial bridges is because we need to manually forward the mac addresses of the devices behind the bridge. These are being installed on robotic forklifts. They have a generic ethernet scrolling marquee installed that does not maintain any active connections and drops from the fowarding table in the bridge if not staticly configured. I'm looking for an alternative because the roaming is not nearly as smooth as it should be.
I want to connect with wireless devices two buildings, one in front of another. Short distance (about 20 meters) and no obstacles. I have a couple of aironet 1242 and i was wondering if it would be possible to setup this link with this equipment.
I'm looking to bring up a wireless bridge between 2 WET200.I've set in Wireless -> Basic Settings and Wireless -> Security the same parameters in both devices, but it fails.
I am interested in purchaseing a WET610N wireless Bridge for my new XBOX 360 to connect to my existing wireless, and wire network. I was wonder if the device can be connected to a 5 port network switch and used on multiple devices such as my TV.
I have a DLink wireless bridge connected to the wireless WRV210 router. All devices connected to DLink can access internet/email fine and can ping the WRV210, however, they can not ping any device connected to the WRV210 router, nor can any device on the WRV210 ping devices on the DLink writeless bridge. All devices are on the same subnet, 192,168.100.X with mask 255.255.255.0. All devices get their address from the WRV210.
I have cisco's CUCM version System version: 7.1.5.10000-12 when I do a corporate lookup (form my 7970 I hit Directories - 5) Corporate Directory) I see all sort of accounts that have no phone extensions I.E. our windows service accounts, our administrator accounts that have no number associated with them. is there a way for me to hide them?
I know that when you surf the web, websites can log your IP & MAC address.If you get my jist, I don't want my laptop to be flagged on a few web sites I have been on.My plan is to use another pc, that has a wireless braodband dongle from a mobile phone company.The pc will be attched to the wireless router via eithernet, but banned from access the web via the router. This way I can connect remotley from my laptop.
Privacy in the web, I have a new laptop and I want to know if my verizon router will store my browsing history if I use Incognito mode or privacy mode? Because I don't need people seeing what I was doing.
I have a win 7 pc networked to several xp desktops and notebooks, nas, wired network printers, and all works well. Its no big deal but everything I look at to do with my network on my win7 pc says its network5. Is there a way to have this network 1 which I assume it was once? Does this mean that there is also junk hiding within my network as to the configuration of 4 earlier networks?
I'm using two cisco 1242 AG access points to configure WDS feature. I've named the accesspoints as AP1(acts as WDS) and AP2. Since I've only two accesspoints, I've configured the AP1 to act both as a WDS and as a regular accesspoints.Further I'm using the local radius server within the AP1 to authenticate both clients and infrastructure accesspoints. And both APs are connected to a router (which act as a dhcp server) via a unmanageble switch and both accesspoints are getting registered with WDS.But the issue is when I tried to connect to the configured SSID, it promts me a "authentication window" but after entering the configured username and password, i'm not getting authenticated by the AP.
I've attached the configurations of both APs to for your reference and I've used the following cisco document as a guideline to crate the WDS. [code]
I'm having a little issue with some Cisco Aironet1242ag WAP's. I receive a call at least twice a month stating that some of the WAP's are not giving out internet connection. What I always do is go to my patch panel and disconnect those WAP's not working and connect them back again so they can power cycle. These WAP's are connected to a Cisco3750g. Once the WAP's boot up, the users can connect to the WAP and connect to the internet.
I don't know if these WAP's are filling up with some information that causes the access points to not connect to the WAN.
I am trying to upgrade an autonomous IOS 1242 AP to LWAPP and I am having an issue with finding the right code to complete the upgrade. I have upgraded the AP to c1240-rcvk9w8-tar.124-21a.ja2.tar, but now I think I need a JX version of code to have it join a controller, and I can't find this anywhere on the Cisco site.
i need to change the IOS in a Ligthwiegth Access point and make it work as an Autonomus AP 1242. I have got the image but im not realy clear about the process. I got to enter the Ligthwiegth Access point true the console port but i dont know how is the upgrading process.
One of Cisco Wireless AP 1242 installed in my premises restarts itself; AP is getting power from Catalyst 2960 POE. I am using multiple SSID on this AP. I have issued the show tech-support. I have seen below in tech-support System was restarted by unknown reload cause - reason ptr 0xF, PC 0x46FEB8, address 0x0? what could be the reason of restarting of AP. AP is in production since 1 year and it restarts seldom.
When I tried to add new AP 1242 to my network I had following problem:
The Ap was constantly reloading and I was getting message
Wed Mar 20 13:32:12 2013 AP 'UBFT-E06-F0A-R09-0022.901b.a6ba', MAC: 00:23:ab:27:1f:30 disassociated previously due to AP Reset.
%CAPWAP-3-IMAGE_DOWNLOAD_ERR3: capwap_ac_platform.c:782 Refusing image download request from AP - unable to open image file /mnt/ap_bundle/ap.pri//c1240
I decidet to reinstall software on WISM 2 modul (7.2.111.3) this fix the problem and AP joined controller but during this process I have lost connection to 87 AP for 3 seconds and then they joind back again.
I have 3 Cisco 1242 WAPs that I have deployed at a site that has NO RADIUS/AAA devices. I have given all of them a different channel (1,6,11), but the same SSID and crypto (WPA2-PSK). The issue is when a machine boots up it associates with the closest/strongest AP, but as the device "roams" it does not which to a different AP. It stays associated with the original AP until that signal is gone. Then it quickly associates with the closest AP with no problem.
How do I get the device to associate with the strongest WAP? I have research "fast roaming and WDS" but it seems like you need EAP/LEAP and they do NOT have that at all.
We recently purchased an SRP527W router because of its capability to configure site-site VPN tunnels. The configuration of IKE and IPSEC is working and the tunnel comes up but the problem is that the router is passing our internal IP addresses through the tunnel. The remote end we are connecting to requires us to hide all traffic behind one IP address which would ideally be our external static IP address from our ISP.
We 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.
I encounter a strange problem on several AP 1242 in version 12.4(25d)JA1 of a customer : He has 10 autonomous AP covering The APs loose LAN connectivity randomly and therefore the clients don't work anymore. The AP are connected on a 2960 and a 3560 wich are in turn connected on a 3750 wich route the trafic.After checking spanning-tree no loops are present. When I check the counters on the AP involved I see the "trhottles" and "ignored" counters incrementing on the fa0 link of the AP impacted wich mean I think it can't handle the incoming traffic. This incoming traffic seems not to be too big however. I can see drops on the switch interface connecting the AP.
Currently have access points located throughout our warehouse that use the AIR ANT5160V-R antenna's from Cisco. These AP's are 25' in the air. However we have a lot of voice quality issues off of the 5Ghz band, we do no other services on this band as we keep data on the 2.4Ghz.This was all installed by a vendor but from what I am seeing on the documentation [URL] the cover is extremely poor for these antennas despite AP's everywhere. They cover side to side but aren't a well rounded AP at all.it seems like the AIR-ANT5145V-R would be better suited even though this is a warehouse.
we had a problem with a customer wlan in our warehouse (cannel overlapping). The troubleshoot needed a long time. For the future if requipred in case of problems i want to configure one access point in the warehouse as a scanner (please find picture in the attachement). The Autonomous cisco 1242 is now configured as scanner but i can't see any logfiles? Where can i find these informations. This is the cisco description of the scanner mode:Scanner—Functions as a network monitoring device. In the Scanner mode, the access point does not accept associations from clients. It continuously scans and reports wireless traffic it detects from other wireless devices on the wireless LAN. All access points can be configured as a scanner.
I have cisco LWAPP 1242 AP already joined controller but 802.11b/g shows down on the radio 0 interface. I tried to enable it but it comes with an error" Error in enabling admin status". I have resetted the AP to factory default settings and even replaced with NEW AP.
However, I now have a number of devices... certain smartphones so far... that will NOT connect to a FlexConnect AP if it's a 1262AGN AP, but my older 1242G AP will accept the devices without issue. Same SSID, same encryption standards.
If I connect the devices to my guest network (no security), they will connect just fine to both APs, and Non-FlexConnect 1242 and 1262 APs will both accept the devices without issue using my private network.
In other words, it seems to be an issue specific to 1262AGN with my encryption security. My security is WPA2/AES with PSK. No additional security on the SSID.
I have a set up 50 qty AP1242 (AIR-LAP1242AG-E-K9) installed with a single (1 qty) ANT1728 Antenna..I am not happy with the coverage..Is it possible that I can add another 1 qty of ANT1728 antenna to the exiting AP1242 to imporve the coverage?
AP1242 had dual RPC-TN connected. But I am not completely sure that wether 2 qty of antenna (ANT1728) can be connected to a single Access point (AP1242). I am also concern regarding the power requirement.
I would like to upgrade my existing Wlan to the following configration -AP1242 connected with dual antenna (AIR-ANT1728 x 2 qty) to improve the coverage.
