Cisco 3502i in autonomous mode - for site survey

Hi,
Last year I was able to load autonomous mode IOS to a cisco 3502i to do the site survey using instructions at following thread.
https://supportforums.cisco.com/thread/2084624
This year I have to do site survey for a different site and need to do the same process. However on the CCO I don't see the autonomous image. Under downloads -> products -> wireless -> access points -> Cisco 3502i I see IOS link and when clicked there is gives
ap3g1-k9w8-tar.124-23c.JA4.tar. I even loaded that IOS but it seems to be light weight mode IOS.
After reading a few different threads somebody clarified that K7 = IOS and K8 = Lightweight. However I can't seem to find the lightweight mode anywhere.
https://supportforums.cisco.com/thread/2140629
Can somebody guide me? I need to run this code only for the site survey and totally understand the fact that Cisco would not support such configuration.
Thanks in advance,

Sorry to inform you but there is no autonomous code for the 3500. You could however use the 1140 code. But this not supported by Cisco but it does work ..

Configuring 1142 to use for site survey.

Just got in a bunch of the 1142 N-A-K9 APs. I need to set them up to do a site survey with.
Don't seem to be able to find anything on the site.
Has anyone used yet for site surveys? The radios are off by default.

You can survey with 1142. You can do two ways in lightweight mode. One would be to use it with 2106. This could be cumbersome as you have to carry around UPS so you can power the 2106 and use PoE on 2106 to power 1142. This way you can adjust channels and power levels on the AP as you see fit from cell to cell. Second method would be to configure the AP for HREAP mode on the controller and assign your custom power levels and channels. Then you can just use that AP without the controller to survey and power it up thru a PoE battery pack. The custom power levels stay on both 2.4 and 5 GHZ radios but channel only stays on 2.4GHz. Due to FCC and DFSS the 5GHz channel will most likely change each time you boot the AP. If you keep the AP on the battery pack for the duration of the survey it will stay on the same channels. So the negative to the HREAP mode survey is that you can't adjust channels and power levels as you move from cell to cell easily as you would have to connect it back up to the controller. Surveying with 1142 is helpful as from my experience they have a better footprint than 1131s. Hope this helps.

Config for using 1242 for site survey

Hello, i'm helping a coworker, we have a 1242 and would like to use it for a site survey, but we are not able to activate the radio using conf t it is in light weight, are we missing something? were can i find a config example to use for this purpose?

Hi Alfred,
Converting a Lightweight Access Point Back to Autonomous Mode
You can convert an access point from lightweight mode back to autonomous mode by loading a Cisco IOS Release that supports autonomous mode (Cisco IOS release 12.3(7)JA or earlier). If the access point is associated to a controller, you can use the controller to load the Cisco IOS release. If the access point is not associated to a controller, you can load the Cisco IOS release using TFTP.
Using a TFTP Server to Return to a Previous Release
Note This section does not apply to Cisco C3201WMIC and Cisco C3201LAP.
Follow these steps to revert from LWAPP mode to autonomous mode by loading a Cisco IOS release using a TFTP server:
Step 1 The static IP address of the PC on which your TFTP server software runs should be between 10.0.0.2 and 10.0.0.30.
Step 2 Make sure that the PC contains the access point image file (such as c1200-k9w7-tar.122-15.JA.tar for a 1200 series access point) in the TFTP server folder and that the TFTP server is activated.
Step 3 On the PC where the TFTP server is located, perform these steps:
a. Disable any software firewall products, such as Windows firewall, ZoneAlarm firewall, McAffee firewall, or others.
b. Ensure all Windows files are visible. From Windows Explorer, click Tools > Folder Options > View > Show hidden files and folders.
Step 4 Rename the access point image file in the TFTP server folder to c1200-k9w7-tar.default for a 1200 series access point, c1130-k9w7-tar.default for an 1130 series access point, c1240-k9w7-tar.default for a 1240 series access point, and c1250-k9w7-tar.default for a 1250 series access point.
Step 5 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.
Step 6 Disconnect power from the access point.
Step 7 Press and hold MODE while you reconnect power to the access point.
Step 8 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds) and then release.
Step 9 Wait until the access point reboots, as indicated by all LEDs turning green followed by the Status LED blinking green.
Step 10 After the access point reboots, reconfigure it using the GUI or the CLI.

Cisco Aironet 3700 Autonomous Mode

Hi guys,
I was wondering if the autonomous IOS for the Cisco Aironet 3700 series is fully functional, instead of only supporting the site-survey mode.
Many thanks.

Thanks man.
I saw that IOS on Cisco's site too.

Detail workflow for site survey?

Hi All,
I am new in this field. I had saw some information and I can catch the basic meaning of wireless LAN. But I can not find any information about the detail workflow when doing site survey and how to work when an AP doing as site survey client, also when a bridge work as a repeater. When will a client doing a site survey? and the detail workflow of site survey? Is there any problem that may make site survey fail? Does any body know it? Can any body give me a hand? Thank You!
Best Regards

Here are a few URL's that should help you with the site survey. These links have a list of things that could interfere with the site survey. http://www.cisco.com/univercd/cc/td/doc/product/wireless/airo_350/350cards/windows/incfg/win5_apf.htm http://www.cisco.com/univercd/cc/td/doc/product/wireless/airo_350/accsspts/ap350scg/ap350ch3.htm#1016921

Question about WLAN Site Surveys with 802.11n APs - 1142s

I do site surveys a little differently that everyone else nowadays, I believe. In the past, I used an autonomous 1230 or 1240, but now I use a lightweight 1142. I configure a port in a room to be on the AP VLAN and I connect my 1142 to the port and hang it where I want - it then gets on the controller and start broadcasting just like the finished product will. This works well except for the time it takes me to configure a port on the switch and the bootup time for the AP. I'm one of the Networks Architects on a campus of almost 200 buildings, so I have access to all the routers and switches and can configure anything I need while onsite.
Now I want to have someone else (in-house) to do our surveys - but this person(s) does not have access to switches and routers, and that won't ever change.
I tried configuring a lightweight 1142 in HREAP mode to handoff to this person, but it appears the power and channel settings don't stick on the 5 GHz side.
Scrapping that idea, I now have to build out an autonomous 1142 for site surveying. I missed out on this step because I went from buying 1242s (can jump between lightweight and autonomous) to 1142s (which didn't have an autonomous image at that time, I believe). This is why I started surveying with lightweight 1142s.
I'm curious if anyone has gone through the configuration of an autonomous 1142 and wouldn't mind sharing their "lessons learned". I haven't seen a matrix of features that are supported/not supported on 1142s when configured for lightweight vs. autonomous.
I currently aim for designing around the 5 GHz radios set to 10 dBm, 20% cell overlap. I also turn on 40 MHz channels in 5 GHz range. This usually ends up with an AP in every other or every third classroom, depending on how old the building is and how many times it has been renovated. I can't "just throw APs out there" since each building is different - some are thin concrete block, some are poured cement, and some are block with metal mesh and stucco. Those usually end up with on AP per classroom.
Does anyone have a matrix on what can and cannot be turned on in an autonomous AP? I would like to get my config as close to the lightweight scenario we deploy for all of our production WLANs.

There is no matrix as to what you're asking for. I've done conversions and configurations of AP's from Lightweight to Autonomous and vice-versa. The configuration of the autonomous AP can be identical to the Lightweight AP from a client perspective.
My current setup has 3 SSID's (VoIP, Data, and Guest) on the autonomous AP. Couple things I do:
1. PoE powered AP through a Tessco power pack.
2. VLANs have to be enabled on the AP (1 for each SSID)
3. The SSID's will have to be created and each AP mapped to a VLAN
4. The SSID's will be need to be enabled on both radios if desired.
The easiest way to configure the AP is to power it with either the power cord.
Console into the AP and let it boot. Assign an IP address to the BVI 1 interface.
Assign an IP address on the wired NIC of our laptop and plug an ethernet cable into the AP's ethernet port.
Configure the AP as listed above via the web gui.
This is by no means a complete answer, but your questions were all over the map.

Jerry

Help with first time "controller based" Site Survey

We are moving from autonomous 1242AG to "2500 LAP with 2600 WLC"
I am used to bringing 1 autonomous AP to do my Site Surveys, but now that that I have a LAP, does it mean I need to bring a Wireless Controller with me so that the LAP could join it?
What do you guys do? Bring WLC, LAP and small UPS?
Any ideas would be helpful
Thanks!

Hi,
If you only have a LAP now then also you can convert to autonomous AP and do the site survey and then convert back to Lightweight.
You just need the 2 images.
One autonomous image:k9W7
http://software.cisco.com/download/release.html?mdfid=284362264&flowid=34154&softwareid=284180979&release=15.2.4-JB4&relind=AVAILABLE&rellifecycle=ED&reltype=latest
One lightweight image: k9W8
http://software.cisco.com/download/release.html?mdfid=284362264&flowid=34154&softwareid=280775090&release=15.2.4-JB4&relind=AVAILABLE&rellifecycle=ED&reltype=latest
Site survey is nothing to do with WLC(You can go ahead with Autonomous AP for site survey).
On the same place put the LAP and connect to nearest switch.
WLC push the config to LAP and also manages the RRM feature(Power, Channel....).

Showing Full AP name in cisco Wireless phone 7921-site survey

Hi,
I am working on a project where cisco wireless phone 7921 is utilized. We use phones sitesurvey tool for coverage tests. Our AP names are 18 characters in length and are not dispayed in full in site survey screen. Please suggest on a way to increase the display character count in the site survey or to make it a running text. Thank you.

Hi Leo,
Thanks for the suggestion. I looked at the Fluke OptiView XG Network Analysis Tablet. Looks very interesting, but looking at the cost of the Tablet, I am pretty sure that my Employer will say NO.
Anyways, Can you recommend some vendor options (It will be really helpful, if you can share the Model information as well) for the list highlighted below.
1. AP Tripod (Reaches 3 meters max) - Need recommendation on AP Telescopic Tripod which should be portable to carry in the Peli Case.
2. Distance measuring tool - Need recommendation on this.
3. Laptop harness - I did some research and found Connect-A-Desk Laptop Harness, which I am planning to purchase
Also, I need your inputs in choosing Antennas for Site-Survey Kit (I am looking at must to have options for the Kit).
Thanks,
CJ

Site survey on non cisco card

We currently own several Cisco aironet cards which we do site survey's with. As a company standard our laptops were replaced with new laptops which did not include type II pcmcia slots. Is their a solution for the express 34/54 slots to work with the Cisco aironet site survey software?

I have seen PCMCIA to USB adapters but I think they need to be cutom made for each type of PCMCIA card. Does anyone know of a suitable adapter?

Site Survey with ap3500i

Hey,
I have a question about sitesurveying with ap3500's
I'm going to deploy a wireless network in a new building, i have a company that normaly does my site surveys.
I normally provide them with some AP's configured with a designated ssid and local power modes set to 50%, however this does not seem possible with the new 3500i's i'm willing to use, for there is no IOS image available for it.
I dont have any network connectivity yet in this new building, so i cannot f.i place them in a separate ap-group and assign a dedicated wlan to them.
Can Anybody think of a viable solution (ASAP) Thanx in advance

leolaohoo wrote:We use 1140s for site surveys in our 3502i deployments.Not recommended.
I have the same questions as Thomas. In the thread below I tried to find out any differences between these APs but the consensus was that ClearAir was the only notable difference. The only way the 1140 would be not recommended for a passive survey is if there is differences in the antenna pattern, and active survey if there's a difference in chipset or hardware. So what are the differences?

Wireless RF Site Survey Tools: Do you have a preference?

Our customers are asking us with greater frequency to work with them on deploying high performance wireless networks that are secure, reliable and support end-to-end QOS. We recognize to do that professionally requires great site survey RF tools.
We are considering AirMagnet's "Survey Pro" with their integrated "Spectrum Analyzer." We would run them on a Lenovo 802.11abg PC.
However we have seen some discussion on here regarding Cognio's Spectrum Analyzer and we have also found the Exahau "Site Survey" software product will speak with a Fluke 802.11 radio.
We are looking at investing in a tool set for our Wireless practice and we want to ask you what are your favorite site survey and spectrum analyzer tools? Thanks for taking the time to respond!

Apart from all the features Sales folks pitch about from both these companies the intuitiveness (ease of use) and accuracy make a lot of difference.
I would suggest getting trial copies of both of these tools and using them in the field before making a final investment.
Personally I have used AirMagnet Spectrum Analyzer (a separate product) and has been impressed by it. It comes in both laptop as well as handheld formats.
For site surveys I have used Wireless Valley which is also very impressive.

Cisco 1572 Outdoor AP in Autonomous or Site Survey mode?

Can a 1572 outdoor AP be put into an Autonomous mode, or at least a Site Survey mode so coverage areas and signal strengths can be tested without the need for a wireless controller?
If so, is that what the sku "SW1570-UL01A01-K9 SW Cisco AP1570: Unified LOCAL" is for? Seems like it would be, but not sure..
Thanks!

Got the answer to my own question... yes, it can be deployed in Autonomous mode... Installation guide lists this at the very end of the doc...

Site survey for 3502i access point

Hi,
I want to do initial site survey to fix the location of 3502i but there is no existing lan-set up where i can connect and do the site survey.
I do not have autonomous ap as well.
do i need to wait to get ethernet lan up and connect my ap and get registered ap with WLC and then fix the location or is there any other way to do site survey?
Please suggest me .

There is now available beta code for autonomous 1260 series APs. You could reach out to your Cisco contact and try to get that. The 1260 and 3500 series APs are identical with the exception of the spectrum capabilities in the 3500. So you can survey for a 3500 deployment with an autonomous 1260.

Wireless site survey doubts with cisco aironet site survey utility tool

Hi,
I have 1131 autonomous AP and we have project where we need to implement WLC 5500 with 1140 LAP.
Before that , we need to do site survey . we are going to use cisco aironet adapter and with the help of site survey utility tool we are planning to do site survey .
I have below doubt before starting the site survey :
1) do we need to configure the AP 1131 with existing LAN set-up of client to get connected ?
If yes , how can i shift this 1131 ap always from one location to another location and connect to respective vlan in switch ? It would be tedious job ....
because , We need to connect ( get associated ) our laptop always to 1131 ap and then roam around to get the RSSI , signal strength , SNR and throughput .... ...
to configure the AP to existing lan set-up of client , it would not be flexible to do site survey ?
without that , how can I just plug-in power to 1131 AP with standalone configuration .... and without connecting to switch ( any lan-port ) , do the site survey ?
Please suggest me .............
In short , without connecting to LAN set-up of client , how can i do the site survey ?
2) will it be worth to do site survey with cisco aironet card ( site survey utility ) ? or we should i have different site survey software for the same ?
Please share the knowledge ....

Site Surveys are important and should be done by a professional. A poor site survey can lead to a lot of problems. It would be hard to put all aspects of conducting a proper site survey in a single post. Lets cover a few of the basics.
1) If you plan to deploy 1140 model access points. Then you should use that AP in autonomous mode so you dont have to be plugged into your network
2) The AP gets powered by an exteral power source like this battery for exmaple:
http://www.tessco.com/products/displayProductInfo.do?sku=345625&WT.mc_id=google_base&sp=true
3) As far as moving the AP around you can purchase a site survey pole like this:
http://www.tessco.com/products/displayProductInfo.do?sku=392506&eventPage=1
4) As for software, I like AirMagnet Surveyor

But again. There is a lot to know about doing surveys...

Looking for a beginners guide ot site survey

Good evening,
Getting ready to do a site survey of a rather large facility... About to switch to an entirely different wireless nic (intel 3945ABG) which isnt performing as well as its cousin, 2200BG. Reviewing the stats of the cards it doesnt make sense as intel claims (from my understanding) the 3945 is more sensitive.
Given the sheer size (220,000+ sq feet) of my facility i want to ensure i do this correctly the first time around. I have the given equipment which will be deploying this card.
What i have done in the past for resolving some issues is going every 5 feet and recording by hand the SNR using something along lines of netstumbler. Is this correct?
any suggestions will be great.
