Cisco Wireless :: Few Pins On RJ-45 Socket Are Damaged
Sep 5, 2011
I have a problem with my AP. Basically when I plug it in to the PoE switch it will start up (I can see the lights) but for some reason there is no light on the PoE switch. Looks like there is nothing connected. I chave changed the cable, port on the PoE switch but still the same. Is it possible that maybe few pins on the RJ-45 socket are demaged or there may be sth else.The other APs start without any issues and the light is always on on the PoE switch.I also need to add that the AP can not get the IP address.

I purchased two linksys wrv210 routers and the firmware seems to be damaged. The dhcp server for the router is not working and even if i configure a static ip address on my notebook. I still can access the router via the web interface. I have already tried to reset the router to its default settings via the reset button but that proved to be useless. Can the firmware be reloaded via tftp?

I recently upgraded to an EA3500 router using Cisco Cloud Connect after my E2700 series router was damaged after a power surge came through coaxial cabling to my house and was transfered to the router over ethernet.
I have my EA3500 running both 2.4 and 5 GHZ networks running as 802.11n only and a Lynksis WRT54GS router for 802.11g network devices that are left in my house connected to the EA3500 over ethernet.
Since upgrading to the EA3500 - I have noticed that I am having some trouble with my internet connection dropping randomly that was not present when I was running the E2700 series using the same configuration.
I have not been able to get my full internet speeds as promised by Comcast over wireless (30 Mbps - using direct ethernet I can get upto 40Mbps). My two printers connected via ethernet through an ethernet bridge are being stubborn, the IP address constantly changes. I have not changed any settings in the router other than the network name and setting it up for dual band configuration.

I am trying to FTP a 25MB file to a client using FileZilla and my wired WRT310N router. In the past I have never had a problem but now I am getting the following error: Could not write to transfer socket: EPIPE - Local endpoint has been closed.I changed the MTU to manual - 1500 on the router.I am using an almost brand new iMacThe iMac firewall is OFFTimeout in Filezilla is set to 0.The transfer stops at about 12MB everytime I try; which is ~ 35 seconds.

I have written a java server-client program. The server accepts incoming connections on port 2175 and writes responses on 2176 which the client listens on for the response. I am sending serialzed objects over the network.
Problem: This all works well if I run my client on the same machine as the server. I put together a client jar and deployed it on another machine running on the same wireless network as the server. Now I get a "ConnectionException :Connection refused". So I thought I should hardcode the server and client IP's but that still didnt work.
Question: What else would I have to do to get the two computers to talk to each other (in terms of networking not java)?

I have a tcp socket server application. Some of my clients are asking if I can provide server redundancy for my tcp service for HA purpose. I know it can be done using Windows NLB but the cost of the Enterprise edition is beyond the budget of most of my clients. DNS failover is also out since it will involve fiddling with the DNS server. I'm would prefer to setup a simple solution in which I check the status of the primary server and then if the primary is down, change the ip address of the secondary to the primary so that the service remains available. This sounds simplistic, and besides different clients use different networks, e.g. AD, but I'm not a networking guy so I am at my wits' end.

I have a Netgear WNR3500L wireless router. I assume it's v1 because on the back it doesn't have "v" anything. Firmware version V1.2.2.44_35.0.53NA.When I connect using g I get 22+Mbps download speed. When I connect using n I get 10 Mbps. I've tried using both WPA2 only (laptop reports 130 Mbps connection I believe) as well as the combo WPA+WPA2 (laptop reports connection of 117 Mbps).Broadband download results don't change - they stay at the 10 Mbps level. I've fiddled with some of the settings on my laptop's wireless card - but the results are the same.For now I'm just trying to figure out where I should focus my investigation and fiddling efforts - on the laptop or on the router.

I have a setup involving 3 clustered AP541 running off a sg300 switch. The wireless network setup VAP has one entry for vlan 1 with station isolation disabled. Is there anything more I need to do to allow one wireless client to ping another wireless client - am I missing something - i assume this is possible.Needless to say wireless clients can ping non wireless clients and vice versa quite happily. Everything is running with factory default settings more or less.

I have a WLC 5508, AIR-LAP1142N APs and a SSID for students to connect to who bring their own device. I am still testing this and it has not been rolled out but I am running into some serious issues with joining the network. I am authenticating them through a RADIUS server (2008 R2). Problem: many of them cannot connect because they are lacking the certificate.
1. What is a good setup for authentication in a BYOD environment
2. If my setup is good what can I do to allow kids to use their computers on the wireless either without the certificate (which I know is unlikely) or what do I need to have them do to connect. I am hoping it does not involve hard wiring and getting the certificate from the server.

have a Cisco 5508 controller (version 6.0.199.4) that when I enable global multicast mode it will work for an hour or two and then it will kill the network. All internet both wired and wireless, access to server everything dead. I then have to directly connect to the service port and disable the global multicast mode. Then two reasons for enabling it are Docs2Go and LanSchool both require multicast to be enabled. I have it enabled on our wired network and it works OK there. ted.

We have recently been given this unusual task. The setup is a series of CAP3502P access points, and a wireless controller (either 2500 Series or 5500 Series), as well as other standard network infrastructure.
In this network, the client (mobile/wireless) devices must be able to detect when they change what access point they are communicating through, while also requiring a seamless transition. Ie, if the client device is communicating via access point A, and displaying the application menus for A, when the user walks to the area services by access point B, it must detect that sot he application can display menus for B, without the user having to select "B".
Is there a way for the client device to detect which access point it is using and provide that to an application? Or alternatively a way for a host service residing on a server to get that information from the wireless controller?

i am placing a formal request to Cisco and to the firmware development team to create a new-and-improved firmware release for the WET200 wireless Ethernet bridge, a product that is still being produced, shipped, and sold. I purchased the product about one-and-a-half years ago and have enjoyed its performance. There have been, however, some flaws with the device, namely the following:While configured to use WPA2-based security, DHCP-related traffic is not passed from a router/gateway's DHCP Server to connected devices on the WET200. Current firmware release notes indicate this was a known issue and was, supposedly, fixed; however, due to the level of problems customers are reporting, it appears this may have only been resolved, if at all, with security configurations of WPA, WEP, or OPEN. It has not been fixed for customers using WPA2-based security.When I originally purchased the WET200 and configured it to use WPA2-based security, while it, initially, did have a few problems connecting to my router/gateway, it, eventually, did connect and stayed connected for, approximately, one year. However, in September of 2009, it suddenly lost connectivity with my router/gateway and has not been able to establish a connection since, even after reinstalling the latest firmware revision and after several soft and hard resets of the device. I tested the WET200 with another router/gateway, only to experience the same issue. Other devices are connecting to my router/gateway, but, not the WET200. The last firmware update for the WET200 was dated back in July of 2008. Currently, it is January 2010 and since these issues have been known for quite some time, it is unacceptable that the firmware for this device has not been updated in such a long time, especially when there are known issues with the WET200's firmware. Such lack of support is forcing me and my clients to stop using these Cisco-based products and purchase competing hardware, something I would prefer not to do; however, without better support, I and my clients do not have a choice. Expecting me and my clients to use an inferior form of security on the WET200, such as WEP and/or WPA, until a firmware update is issued is unacceptable, especially when that update has not been released in over one-and-a-half years. Such lack of support is especially unforgettable when my clients and I are looking to purchase new networking equipment. In the past, I would not have hesitated to purchase a Cisco-based product; now, with this experience in mind, I am finding it very difficult to recommend to a client that he or she should invest their organization's finances into Cisco-branded equipment. Proper, professional, timely, support of your hardware is expected of your customers, especially if you wish them to remain loyal customers. I have noticed that other similar devices, albeit, higher-end devices, have had their firmware updated, more recently, compared to the WET200. I assumed this meant that the firmware development team was updating all firmware on such devices. So far, I have been disappointed in the lack of firmware updates for the WET200. While I understand the possible desire to update the higher-end products, first, as a professional whose job is to research, recommend, purchase, install,configure, secure, and maintain both the enterprise-level and small business-level devices, I highly encourage Cisco not to overlook their small business products when the firmware development team is updating firmware for any Cisco products. Deficiency in the support of one strata of Cisco-based products is reflective upon the support of any Cisco-based product and is not easily forgiven by Cisco customers, such as myself, when new and additional hardware needs to be purchased.

Due to lack of wires we decided to extend our network by using WET546 bridge by linksys. Ideally we looking to create topology like this:
(Computer)--eth--(WET546)---wireless----(AP/WLC2100)---(router)---(Internet)
WET546 successfully authenticates and looks pretty healthy on controller (see below) , however neither of computers plugged to WET546 was unable to obtain ip address from dhcp server , nor working with static ip. I was under impression what it might be related to some default policies on WLC2100. Logs (warning) on WLC2100 looks clean.

This is the first time I am trying my hands on wireless gears. I have 2500 WLC and 1142 AP (which I converted from Standalone to LAP).I have a layer 3 POE switch where i am using port 1 for the WLC which is a trunk port.
Port 2 is for the AP using access vlan 111
Port 3 is trunk port going to a router where i am running dhcp server for the VLANs which are as follow:
VLAN 110 -Corp Wireless (10.1.110.0/24)
VLAN 111 - AP-Mgmt (10.1.111.0/24)
VLAN 999 - Guest (10.1.101.0/24)
I wanted to block the traffic from the Guest VLAN 999 but when i apply the ACL on the Guest Interface created on the WLC, I dont see any pings going across and neither I see any hit counts on the deny statement as if the ACL is never applied.

We have a 2504 Wireless Controller and it works great!We currently have 6 Access Points (Aironet 1252) connected.We just added the sixth one a few weeks ago and with a properly configured and fully functioning Wireless Controller, it was super easy.Now, I have been assigned to add another Access Point, but at a remote site.The plan is to have up to three or more APs at this remote location and we want them to talk back to the Wireless Controller.We have plenty of licences on our current Wireless Controller.Do do not want to spend the funds for another Wireless Controller and more licenses.
1. How does one manually add a Aironet 1252 to the 2504 Wireless Controller
2. If the AP is on a different subnet than the Wireless Controller, how does one get it registered?
3. The best for last: Can a Aironet 1252 talk to a 2504 Wireless Controller over a WAN link?

I have problem setting up wireless repeater using Cisco 1242AG access points. Here is the setup and problem - The location has 2 1242AG APs and a WLC (2206) which will be used by PDAs. One of the AP was converted to Lightweight AP and is wired. This AP is up and working and PDAs are able to connect to it. There is 1 WLAN and it uses Local EAP (LEAP) as authentication. Layer-2 security is configured as WPA/WPA-2 with 802.1X authentication. Under AAA servers Local-EAP is enabled and a profile (with LEAP enabled) is used. Local users are configured for login. As said PDAs are able to connect and it is working without any problem.
WLC (LEAP with local users) -----> LAP ----> Repeater AP
But the 2nd AP has to be configured as repeater was configured to repeater mode (refering to the document) and was placed. The WLC can see a client (with APs MAC address) but it is probing. The AP is still Automonous AP. Also username and password is configured for authentication. But still the radio on the AP is not up and it is in reset state.

I have a WLC 2006 running 4.2.130 code with AP1020s.I also have several users that have VMware machines that run various flavors of Linux, etc Virtual Machines on Windows XP Pro.
The Windows XP works fine on the wireless. It is the VMWare Virtual Machine running the Bridged ethernet connection that have problems.
The problem is that the Virtual Machine doesn't get a DHCP IP address from the wireless network.
If the user plugs into the wired network all works fine.I have done some captures that show the DHCP requests going out with the MAC address of the wireless client, but no DHCP replies.
It looks like the WLC is seeing the additional DHCP requests from the MAC address of the wireless adapter and dropping them.The same DHCP server (different scopes) are used for both wireless and wired clients.
The DHCP server shows NO activity when the Virtual Machine tries to get a DHCP IP address.The DHCP server is a Cat 6500 running IOS v12.2(33)SXH. DHCP activity was monitored using debug IP dhcp server events/debug IP dhcp server packets. The VMWare Workstation tried is 6.02-6.04.

We have 2 access switches (3750s) that are both attached to a pair of Nexus 5548UPs with L3 cards over VPCs. Access switch (AC1) terminates our 4402 WLC. The WLC services 4 WLANs and connects to the access switch with a single trunked port. Access switch 2 (AC2) terminates an 1131AG lightweight AP. The WLAN is 10.1.1.0/24 on VLAN 300. Router 1 (R1) VLAN 300 IP is 10.1.1.2. Router 2 (R2) VLAN 300 IP is 10.1.1.3. R1 is the active router for VLAN 300. The standby IP for VLAN 300 is 10.1.1.1. The VPCs between both access switches and the router pair are functioning correctly and trunks are wide open (no pruning).
Wireless clients get a DHCP address from a server on another VLAN. Those addresses get handed out just fine.
Wireless clients can ping 10.1.1.3 (R2). They cannot ping 10.1.1.1 (standby address) or 10.1.1.2 (R1).
I took captures from the WLC and I see the ARP requests and replies from wireless clients to their gateway (10.1.1.1). I took another capture directly from the wireless clients themselves. From there, we see the ARP requests, but never the replies. If I create a static ARP entry on the client, it can ping the gateway just fine.
