After some searching I see many people using power injectors or switches that supploy PoE. I am building a lab for the CCNA Wireless and currently have an old Cisco 3550 PoE switch and a 2106 Controller that I got at a steal of a price. My question is, The 1142 can use the 15.4 Inline Power from the 3550 even though it is not the 802.11af standard correct? If it doesn't then I will need to order a power brick.
View 3 RepliesWe have 5 pcs Cisco Aironet 1142 Access Points without controller at the same building. SSID is same for all of them. Our problem is client connected via wireless disconnecting randomly and continues working after a few seconds. IOS versions are same for all of them you can find detailed information about versions and configurations below.

I ordered a set of hardware that came with CBT videos; however, the videos they sent do not exactly match the hardware and I'm stumped.
I have 3 routers:
2610XM: Indianapolis
2620:New_England
2610:Seattle
Indianapolis connects to New_England with a WIC-1DSU-T1
Indianapolis connects to Seattle with a WIC-1T
The interfaces are up on all three devices and so are the protocols. The videos are of 2500 series routers and they only use the WIC-1T card. When I try to set the clock rate for the s0/1 on New England to 1000000 like the video suggest I get an error "this command only applies to DCE interfaces". Do I not need to set this on the WIC-1DSU-T1 interface?
Whenever I issue router rip and try to set network such as:
router rip
network 10.0.1.0
network 10.0.10.0
network 10.0.20.0
the network won't save on any of the devices. If I show the running-config it shows network 10.0.0.0 I've tried saving the config directly after exiting outt of the config mode, but still only 10.0.0.0
I'm looking to sit the ICND2 exam soon and have discovered that the pair of old 2924XL switches are not going to cut the mustard for the newer vlan commands and other features.
Would a pair of WS-C3550-24-SMI switches be a sensible replacement for ICND2 and possibly up to CCNP? They are available on ebay for about £80 each.
I am new to this forum. I ve been googling for CCNA explorer for last one month. All the versions that i download is not compatible with windows 7 and works fine with windows XP. Does anyone know if cisco has released any new version that is compatible with Windows 7?

View 7 Replies View Relateddesigning a wireless network for an apartment complex. The complex is shaped like like an rectangle, fairly small, maybe 100 feet on the ends and 300 feet long on the sides. There are 130 people that we are assuming may have about 3 devices each that they will connect to the wireless network, potentially simultaneously, as this is in a college environment. We have plenty of bandwidth and down/up speed. We are running 30 megabit down and 10 up. I am planning on having a router with two access points centrally located in an apartment and extending the network out with antennas in each direction from the access points with Omni directional antennas. The Access points that I am planning on using are Cisco WAP200 with maybe a Linksys router, as the router should not have more than 10 connections on it. I need something that will not crash after 10-15 users connect to it because it jams up from overload.

View 2 Replies View RelatedWe are leasing an office space from a building that has it's own network center. This center can be used by each office/company to either house their own networking solutions or utilize their internet access if you plan only to use cloud servers or NAS servers. Our company (4 employees) is using this network center only for internet access with all of our data stored and accessed in our cloud service.We would like to access the internet wirelessly, which building does not provide. We were given one port and shared the link through the use of a switch. So my questions is would an access point add wireless connectivity without any information (ISP?) provided by the network center? I am not sure yet if we will be purchasing a router/AP or device made for to be used as an AP.

View 5 Replies View RelatedWe have a Windows server based network (15 wired computers) and four wireless devices (more to come)We are using a CISCO SA520W appliance in the main building as the perimeter Internet gateway / firewall / wireless access. It all works well.We have a second building too far away for wireless devices to reach the SA520W radio in the main building.The second building is connected via fiber to the main building (switch to switch). Several wired computers are connected to the switch in the second building.We want to provide seamless wireless connectivity as wireless device users move between buildings.
We thought to mount and connect another simple B/G capable wireless access point, via ethernet wire, to the switch in the second building. But we're not sure of the best CISCO/Linksys model to choose for this. The choice should work well with the SA520W configuration and be relatively simple to configure in that environment.We're also unsure of the steps to configure a seamless wireless experience for the roving wireless device users.
We have cisco wireless network throught the whole 8-floor building on Cisco WLC 4402 and Cisco LAP-1242 AP. There are no coverage holes, but sometimes clients are flapping between two access points at different floors with serious loss in throughput. Is there any method to limit roaming between different floors in the building?
View 7 Replies View RelatedI live in a new apartment building which means a lot of concrete. The internet (fiber) enters the house at the beginning where the modem is hooked up to my Linksys WRT320N. From there two cables run through the house:1 to the home office, where two computers are connected through a switch.1 to the living room, where the Xbox, blue-ray player are connected through a switch.I also have a wifi network running from my WRT320N, but as it is at the beginning of the house, there are some black spots in other parts of the house. I tried to fix this with a Netgear repeater, but that keeps disconnecting.
What I want to do know is place a second linksys device in the living room at the end of the already existing cable that will also broadcast a wifi network, but I want this to be exactly the same Wi-Fi network as I already have. What I want to achieve is that I can walk from one end of the house with my iPad, streaming a video, to the other end of the house and that I always stay connected to the internet and that my tabled just picks up the strongest broadcaster, basically the same as with a mobile phone.

I need to generate an ODBC connection to the upm Datasource on LMS 4.1 running on Win2K8. I have successfully built connections to cmf, ipm and rmeng, however UPM keeps failing saying that the Database is not found.
Here are my settings.
Driver = CiscoWorks Embedded Database
ODBC Tab - Data source name = upm
ODBC Tab - Description = Device Performance
Login Tab - Supply user ID and Password is selcted
Login Tab - User ID = lmsdatafeed (i have tried DBA as well)
Login Tab - Password = set using the password I estabplished with the dbaccess.pl and dbpasswd.pl scripts
Database.Server name = upmEng
Network.TCP/IP = HOST=<lms server ip>;DOBROADCAST=NO;ServerPort= 43800
I validated the server port using netstat -a -b -o and matching up the PID with the UPMDBEngine process shown in the LMS Manage Processes window.Windows firewalls on the remote machine and the LMS server are off.
I just converted AP 1142 to LAP using the image "c1140-rcvk9w8-tar.124-21a.JA2.tar".
The WLC is a 5500 with 2 NIC : one on 192.168.0/24, one on a specific vlan 10.20/16
The main management interface is on 192.168/24 but we defined as management the interface on the 10.20/16 network.
For the access points, we use ports on a native VLAN on 10.20/16 with other available VLANS which are used for the wlan networks
We have 1152 APs which work fine on this config but that needed to be registered on the 192.168/24 network, then we moved them in their VLAN 10/20/16 and they work fine.
We also have 1142 APs which have been upgraded to LAP. These AP do not work with our architecture. They register correctly on the 192.168/24 network, but do not give access to the wlan VLANs. If they are moved in the 10.20/16 network, they don't register to the WLC (message : Timed out while waiting for ECHO repsonse from the AP). The AP do not get an IP.
is there a restriction with VALNs on these AP ? or is something false ?
I have an 1142 AP that I am unable to set back to factory defaults.Here is what I have done so far:
- boot AP while holding down the mode button
- ap: delete flash:private-multiple-fs
- yes
- ap: boot
- when the AP boots fully I try and enter any lwap ap commands and get "ERROR!!! Command is disabled"
- the AP name and password were reset to defaults but I am unable to get the IP address cleared.
I've also tried "clear lwapp private-config" and get an error saying the command is disabled.
I need to convert some 1142 APs to lightweight mode. They will connect to controllers running 7.3.101.0. I noticed there's two options of Lightweight IOS code available c1140-k9w8-tar.152-2.JA.tar and c1140-rcvk9w8-tar.152-2.JA.tar. Whats the difference between the two versions of code?
View 4 Replies View RelatedWhen we take a look at the internal antennas on the 1142 AP, we notice the 5ghz pointed all the same way, but for the 2.4ghz we can see each offset by 45/120 degrees. It was my understanding that all antennas are omnidirectionals on the 1142, why are those 2.4ghz antennas not all pointed the same way? onfiguration advantage and that each antenna is indeed omnicadirectional? Example, if I shut just one antenna off, do I lose a sector (120degree)?
View 5 Replies View RelatedI recently purchased another 1142 AP to expand out our current wireless infrastructure, my question is, what exactly needs to be done for this to work so that users can roam freely and auto-connect to the closet AP with the best connection without getting disconnected?
I have set all the settings the exact same on the new AP to match the existing AP. (How to save the configs into a file would be great, I am not sure how to do that)... But anyhow, before I launch it, I would like to be sure I am correct so I do not bring down the existing network. Of course, the only difference between the 2 are the IP addresses. AP1 is 192.168.2.2 and AP2 is 192.168.2.3
All computers are using Linksys Wireless-N cards.
The last three new APs I have received from our supplier (official Cisco 1142 LAPs) have all successfully connected to our 4400 series WLCs but are all reporting as being in an Operational Status of 'Down' ie their A/B/G/N radios are not broadcasting even though the APs are all in an enabled state. Furthermore, there is no steady green light showing on the APs - there is no light showing whatsoever (although they were displaying the familiar red-orange-green lights while they were pulling down the IOS images from the WLCs).
The only strange thing I have noticed is that in the AP config screen, the ‘Mini IOS version’ is shown as being v7.3.x. The other – working APs – we have of the 1142 series show v3.x. I know that controller code v7.2 and above only work with the newer 5500 and 7500 series WLCs. Could this be the issue and have any of you seen this issue previously? I am running WLC code v7.0.230.0.
that cisco ap 1142 will support WLC2506 or not .

I have removed the ip addresses for security reasons.
I am a bit confused of the repeater functionality in the mentione AP, my concerns are:
1- Will each radio be dedicated to one function (for example 2.4 GHz for user access and 5.0 GHz for repeater functionality)?
2- Will the internet speed for users be affected when using the access point in repeater mode (no ethernet)?
3- Can an Autonomous AP function as a repeater?
4- Is there any license required?
5- What is the signal overlap requirements between the two Wired and non Wired AP?
6- Can the non wired AP be work as a repeater for another non wired AP (similar to cascading)?
I have recently been adding a number of installed APs to heatmaps in NCS and am very confused as to the correct Azimuth and Elevation settings.
In particular - if the AP is mounted on a wall rather than a ceiling what should the settings be ( and does it matter - perhaps - as NCS is now dynamic by default rather than the old WCS being predictive perhaps it does ).
Any guide for this covering the following common installation locations.
All referenced when looking at the map view in NCS, front of AP is the side with the Cisco logo and the status LED:-
1. AP ceiling mounted ( Backplate pointing out of map towards your eyes - front of AP pointing down to floor )
2. AP wall mounted ( front of AP pointing upwards towards the top bezel of the screen )
3. AP wall mounted ( front of AP pointing right towards the right bezel of the screen )
4. AP wall mounted ( front of AP pointing down towards bottom bezel of screen )
5. AP wall mounted ( front of AP pointing left towards left bezel of screen )
