Cisco Wireless :: 1242 / 2504 - Warehouse AP And Antenna Choice
Dec 23, 2012
We'd like to work with Motorola MC3190 a/b/g handheld scanners in our warehouse so we need WiFi connectivity there. The warehouse has concrete walls and is divided into two parts - loading bay 18m x 42m (59ft x 138ft) and main warehouse building 44m x 42m (144ft x 138ft). The loading bay is just a simple hangar with gates mostly open, temperature could be very low there, down to -20C, the right thing would be to install an external AP there but still I want to get along with the signal from the inside.
Some very basic site survey with the Cisco 1242AG ap shows that there is -70db signal at the loading bay from warehouse AP. What do you think about mounting the antenna at the loading bay and connect it to the AP inside the warehouse? The actual ceiling height is 8m (26ft) but the steel beams are 6m (20ft) from the floor and that will be the mounting height of the AP's. (I think it's rather high though). Storage racks are made of metal and are up to 7m (23ft) high. Stored materials are mostly different types of fiberglass cabling, polyethylene, steel cabling, steel wires, metal barrels.
The environment is very dynamic and it's rather hard to predict the actual RF situation so I'm trying to determine the worst case scenario. So I'd like to use 2504 wireless controller with five 3502e AP's with ANT-2422DW dipole antennas mounted at the ceiling beams in the warehouse at 6m height. My thought was to set scanners to work in b/g band (there will be several laptops there too). There is a little diagram attached below.Still think it's too high, and doubt about the antennas. Are there better choices for such a setup? Maybe with wall mounted antennas?
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.
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.
I have a Cisco Aironet 1242G and an outdoor omni 12 dbi antenna. I hooked it all up to day (antenna is connected with a 100ft cable). My signal is very disappointing. I have it behind a garage and can only get about maybe 75 foot away and the signal gets very weak.
Is there something that needs to be configured in the aironet? I have enabled external antenna and played with the settings. Is the 12 dbi antenna just too much?
I'm planning to use these with a 2504 controller. However, I cannot find a straight answer on whether or not the External Antennas provide better coverage than the Integrated Antennas? These will be wall mounted in a combo office/warehouse environment. Also, I cannot figure out if the External Antennas are even included with the 1602E (AIR-CAP1602E-A-K9)? or what if any power adapter/ injector is included with the AP's?
I have to set up a new wireless infrastructure on a large warehouse. I have a 5508 with 15 APs 802.11b/g so far.A new area of the warehouse (indoor) is ready to be used with new wifi devices and I want to isolated the legacy operation from the new one, because new wifi clients are very sensitive. So I have a few question:
- Can I use my existing WLC (5508)?.
- What is a good 802.11n AP model for this environment?.
- What antennas to use with 802.11n APs?
- Is there any restriction on the WLC I should keep in mind?
I am doing a predictive survey for a very large mixed environment facility.I have advised this customer that it would be best to have a professional site survey done and he understands but has requested I do a preliminary predictive survey and recommendation. This will have both open area manufacturing and also warehouse type areas with 18ft racks and cages, The actual ceiling height is approx. 30 ft. but the building steel I-Beams are at 18 ft and would be the mounting height of the AP. I already have several installs in other buildings with the exact same structure and setup using 1242 AP and AIR-ANT2465P-R and AIR-ANT5170P-R patch antennas mounted to a board, pointing down and at 18ft.
My question is: I would like to use either the 3500E or 3600E AP with diversity patch antennas (3600E & air-ant2566 for example) but see that Cisco also recommends the 2dbi stubby Omni dipoles in this type environment. I'd just like to get some opinions and thoughts on AP and antennas.

I'm currently configuing the WRT54G2 to port forward to an FTP server we have on our network.
The issue I'm having is that the router is offering me the 192.168.40.* range, however the FTP server is in the 192.168.10.* range. The server works on the local network across several computers, however this issue I beleive is what is preventing me from having it accessed from outside the network.
Any options for getting it to offer me the 192.168.10.* IP range?
We are replacing a DS3 Internet connection with a 100 Mbps fastE connection from a Tier 1 Provider. I currently have a Cisco 7204VXR with 512 Mb DRAM and 128 Mb of Flash and two 10/100 ports that is connected to the DS3. I also have a 3845 with 1 Gb of DRAM and 256 Mb of Flash with two 10/100/1000 ports available.
We are currently running BGP, below is the summary
BGP table version is 88880414, main routing table version 88880414 379041 network entries using 44347797 bytes of memory 379043 path entries using 19710236 bytes of memory(code)
It seems it's time to let my trusty but ancient CAT: Networking(Tomato Firmware)because it has problems downloading downloading torrent of 1.0 MB/S and plus.My friend recommended me the Asus RT-16 but it's too expensive for my taste. So I'm looking at the WL-520GU with the TomatoUSB firmware. Can it handle bittorrents with no problem with QoS enabled? Is the 16 MB ram enough to run services such SNMPd?
I'd like to ask you which wwan card is the best choice for a dell latitude e6400 laptop.Is it correct that the version 5540 is the newest and probably the best one?
I am considering the RV180 as a wired router replacement to my current wireless and I can not find any user reviews, comments or ratings. I live in an area with a very poor wireless reception for our Sprint Cell phones (Still under contract) and I have a Sprint Airave which boosts the wireless signal for the cell phones. The Airave transmits on a 2.4Ghz band and it is stepping on my Internet wireless signal causing poor reception thought my 2-story house.
Due to this problem, I am considering installing a business class network with a router, PoE switch, and a strong Access Point. My house is pre-wired for with CAT5 wiring. I have looked at the EnGenuis EAP-350 Access Point (800Mw and 29dBm gain and PoE), The RV180 Gigabit Router, and the Cisco SD208P 8-port gigabit switch with 4 port PoE support for the Access Point. The switch will be located in a wall junction box so I need a switch with minimal ventilation requirements. Is the RV180 and SD208P the right choice to integrate in my network?
My experience with Linksys and Cisco products have been Great so I would like to stay with Cisco. I have looked at a competitors router (Netgear FVS318G-100) but the user reviews were very poor. I am not sure if I need a managed switch or not, as I will have one primary laptop running during the day and up to 3 other computes(2 laptops & 1 desktop), a wireless tablet (android), and a Xbox (wired connection) for the family (of course not all running at the same time).
A client I have just taken on wishes to provide internet data and VoIP for multiple tenants in their new office they move to in a few weeks.
they currently have a Cisco 2811 router with a 24 port Catalyst 2960 PoE managed switch serving just their staff and one tenant company who is plugged into a single port on the switch. I dont know what the tenant has the other side of that at this time.
when they move they currently will provide single port access points on the switch for each tenant, so the tenant can deal with their own network LAN. The client will provide phones to all the tenants using VoIP phones on a single subnet and hosted on an external PBX the phones all plug into the Catalyst and use the PoE. the WAN is a 20mbps fibre connection.
The client has 16 staff, the tenants are 3 companies with 3,6 and 9 staff. They may all increase or decrease in size to a total size of about 30 or 40 people.
I have a few questions
1. should I look at Vlan setup for this instead of the current basic routing setup or is that overkill since they only use one port access point per tenant as gateway.
2. can the cisco 2811 handle this or is it a bit old.
3. what router replacement would be recommended for this task given the above info especially if I went with Vlan solution.
4. any thoughts on the current switch's capability for this task.
5. managing bandwidth solutions? is there any router designed with this in mind. the ASA maybe or something like it with nice visual webgui management capabilities for monitoring and controlling bandwidth use of tenants? Mark
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.
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 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.
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.
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.
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.
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?
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. [code]
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.
