Scanning Access Points configured with JAPAN channels - 184,188 etc

Hi,
I have configured the below mentioned configuration for my Access Point. These wireless networks are not appearing in windows client network list. I have tried explicit scan also. Still it is not showing networks with 184,188 channels. But it is showing all remaining networks.
Country code: JAPAN
SSID for WLAN 1: Wireless Network1
WLAN 1 mode: 5 GHz 54Mbps (802.11a)
WLAN 1 auto channel: Enabled
WLAN 1 channel: 184 (4920MHz)
WLAN 1 alt. channel: 188 (4940MHz)
SSID for WLAN 2: Wireless Network2
WLAN 2 mode: 5 GHz 54Mbps (802.11a)
WLAN 2 auto channel: Enabled
WLAN 2 channel: 188 (4940MHz)
I am using CISCO AIRONET 802.11a/b/g WIRELESS ADAPTER. This problem can occur due to the following reasons.
(1) Do I need to set any region settings at Adapter?
(2) Does adapter firmware depends upon
country? How do I check the adapter firware?
(3) Is there anything wrong with adapter vendor driver? Do I need to set anything in driver level for supporting JAPAN channels.
Anyone please help me to identify and resolve the above problem.
Thanks

Ensure the world mode in the adapter is enabled so that it can scan any of the country channels. Ensure that the Broadcast option is enabled for the WLAN and that the SSID has been enabled on the corresponding Radios of the access point .

What channels are available? The 802.11b standard defines a total of 14 frequency channels. The FCC allows channels 1 through 11 within the U.S.; whereas, most of Europe can use channels 1 through 13. In Japan, you have only one choice: channel 14.
An important concept to note regarding channel assignments is that the channel actually represents the center frequency that the transceiver within the radio and access point uses (e.g., 2.412 GHz for channel 1 and 2.417 GHz for channel 2). There is only 5 MHz separation between the cente frequencies, and an 802.11b signal occupies approximately 30 MHz of the frequency spectrum. The signal falls within about 15 MHz of each side of the center frequency. As a result, an 802.11b signal overlaps with several adjacent channel frequencies. This leaves you with only three channels (channels 1, 6, and 11 for the U.S.) that you can use without causing interference between access points.

301 access point configuration

In Nokia manuals I found no information about access point configuration.
In my 301 I have two “path”.
1). at configuration/data communication/access point. There I see 10 access point configuration.
2). at configuration/personal configuration. There I can create detailed “personal” configurations and later can use it as active.
Question #1: what is the priority between 1 and 2? I mean 2 overwrite 1 or this two have coexistence?
Question #2: At personal configuration I can assign a flowing type of “subconfiguration”: “Web”, “Multimedia”, ” Continuous download”, “Access Point”. What is scope of each subconfiguration? I mean for example “Web” and “Access Point” is not a same?
Question #3: There is any useful manual about 301 access point configuration?
Thanks for any advice…

None. That first path you mentioned, that ‘active access point’ is just for computer tethering …
kzsolt wrote:

Can be. ‘Access Point’ is the preferred access point which your Nokia uses for all its built-in apps. With ‘Web’ you can override that for HTTP(S) based apps because some operators did have WAP proxies in the past. Nowadays, with modern contracts, you just create one Access Point account, there you specify the APN. And then you create a Web account and leave it at its defaults.
kzsolt wrote:

Not aware of. This concept was introduced in 2004 and I never met anyone at Nokia who understood that concept. Therefore, Nokia has problems to explain it. Actually, the software engineer who created it in 2003/2004 did not understand it either because, from the user interface, it is not possible to create a WAP proxy for an ‘Access Point’ which left many users in the dark …
Therefore, if you have a question, just ask us, please. Did that help?

Do somebody knows what´s the recommended heigh to install an access point 1242 with external antennas 1728 on a flat area?

Do somebody knows what´s the recommended heigh to install an access point 1242 with external antennas 1728 on a flat area?And for example, if i use aps 3602 the heigh to install is the same?? BEST REGARDS

To determine the required height of an antenna tower over a hypothetically flat, spherical Earth, it's necessary to calculate the effect of the Earth's curvature, and then add a distance equal to 60% of the radius of the First Fresnel Zone. The table below shows the result of these calculations. Values have been rounded up to the nearest foot.
Line of Sight Distance Between Antenna Towers
Height of Tower to Avoid Flat Earth Curvature
Tower Height Required Over Tallest Obstacle In Line-of-Sight to Provide

It can be seen in the table above that a wireless link between two points separated by 26 miles would require an antenna tower with a minimum height of 103 feet for an 802.11b/g radio and 95 feet for an 802.11a radio. In practice the heights would typically be 20 feet higher, or more. This is because the Earth is not smooth and flat and the tower height must be raised to compensate for buildings, trees, hills, or other obstacles. For example, in a suburban setting, with houses and small offices, it may be necessary to add 20 to 40 feet to the tower height to get over the homes, offices, and trees that would be in the line-of-sight between the two towers.

Wap200 wireless access point configuration

hi guys
I have a wap200 wireless access point configured and connected to the switch 2690 switch on vlan1, when I connect the wireless access points to the switch the port become disabled, is there a way to overcme this problem.
thank you

Hi Senzo.
Do you know the reason for the port becoming disabled? Can you run a "show int status err" on the switch and see if it give a reason for the port shutting down?

SmartConnect fails when GPRS access point configur...

I am trying to configure SmartConnect to cycle between a Wi-Fi and a GPRS access point.
The GPRS access point allows only HTTP/HTTPS traffic through a proxy server (this is a limitation of my service package through the mobile operator; direct Internet connectivity is much more expensive).
When using an HTTP application (e.g. Opera, Gmail) directly with the GPRS access point, everything works fine.
However, if I use the application with the SmartConnect access point, the connection fails.
Just for testing, I replaced the GPRS access point with one that allows direct internet connectivity without a proxy server (at a much higher cost) - everything worked fine.
So, I concluded that this is a bug in SmartConnect - they didn't take into account the fact that the access point may work only through a proxy server, and maybe they do some kind of connectivity check that is not HTTP and that fails. I tried to look everywhere support contact information for Birdstep but couldn't find any.
Has anybody encountered this? Or does anyone have contact information for Birdstep's support? I am guessing the fix probably super-simple.
==============================================
Summary of my settings:
Device: Nokia E51
Access Points under Connection settings:
1 - "Home WLAN" - WiFi, my home WLAN network
2 - "IL Orange WAP" - GPRS with Proxy Server that allows HTTP/HTTPS to the Internet (and unlimited WAP)
3 - "IL Orange Internet" - GPRS without proxy server that allows direct Internet connectivity without limitations
SmartConnect configuration that doesn't work:
Priority 1: "Home WLAN"
Priority 2: "IL Orange WAP"
SmartConnect configuration that does work:
Priority 1: "Home WLAN"
Priority 2: "IL Orange Internet"
Does SmartConnect perform some connectivity check prior to "releasing" the connection to the applications?
===================================================

Just got this from Birdstep's support:
"SmartConnect is not using the proxy setting of the connection. This is known problem with SmartConnect. Currently there is no fix or workaround for it".
So that seems to be the end of it, for now at least.

Access points configuration

What is best practise to configure 10 access points? working on project in big warehouse.
Sent from Cisco Technical Support Android App

Hi,
You can use any option you like to get the access points to join the WLC.
If the access points are on the same subnet as the WLC then you can stay with basic layer 2 discovery method that what the AP will do is once it gets an IP address if will send a broadcast request on the same subnet to join a WLC and since there is a WLC on the same subnet it will reply back and the AP will be able to join the WLC.
If the access points are on a different subnet then the WLC you need to use a layer 3 discovery method so that the AP can learn the IP address of the WLC that is on a different subnet and send a unicast join request to the specifc IP address.
The options would be option 43 or DNS lockup.
DNS option.

Nokia Email Access Point Configuration Disappeared

I`ve just upgraded to the new Nokia Email client on my N95-1 (model RM-159). It says it's version 9.04 (21).
Since upgrading, I haven't been able to configure the Access Point to be used by the email app, which used to be under General|Service Info. This is quite important to me, since I only want to let the app work when using WiFi.
Does anyone know what happened, or how can I fix it ?

This works for the E71: for the time being a workaround for the access point problem:
I set my SmartConnect connection (you can only download this from the Download icon on your phone) group as the default APN, I have the client using Wifi if available and the cellular network if not. This MUST be configured at initial setup, ie when you install Nokia Messaging, change it from "default" to the SmartConnect access point group.

Cisco Access Point Configuration to support 802.11b & 802.11g protocol

How do i Configure access point to support both 802.11b & 802.11g clients on a Cisco 1121G series access point(AIR-AP1121G-A-K9)
Regards
Hitesh

Hi Hitesh,
Check out this excerpt from the 1121g AP Installation guide section on enabling the 802.11b and 802.11g radios.
In Cisco IOS Release 12.3(4)JA and later, the access point radios are disabled by default, and there is no default SSID. You must create an SSID and enable the radios before the access point will allow wireless associations from other devices. These changes to the default configuration improve the security of newly installed access points. Refer to the "Configuring Basic Security Settings" section for instructions on configuring the SSID.
In Cisco IOS Release 12.3(2)JA or earlier, the access point radio is enabled by default, and the default SSID is tsunami.
To enable the radio interfaces, follow these instructions:
Step 1 Use your web-browser to access your access point.
Step 2 When the Summary Status page displays, click Network Interfaces > Radio0-802.11B or Radio0-802.11G and the radio status page displays.
Step 3 Click Settings and the radio settings page displays
Step 4 Click Enable in the Enable Radio field.
Step 5 Click Apply.
Here is a link to the actual document:

Capturing MAC Addresses from an Access Point AP1131 with SNMP

Hi!
I'm trying to use SNMP to track information as to whats connected to
our access points. The purpose is basic security and auditing in case
of a problem ( virus, technical problem, etc ). We're already able to
capture what wired devices are connected, but not the MAC addresses of
the wireless clients.
We're employing Cisco Aironet APs 1131, and looking around the MIBs, I found
one object that has what I want, but it's not accessible.
cDot11ClientAddress OBJECT-TYPE
SYNTAX MacAddress
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"The MAC address of the client."
::= { cDot11ClientConfigInfoEntry 1 }
Does any one know another way to get this information via SNMP?
Thanks U by advance!

Cisco Aironet 1240 AG Access Point - configure Mac Address using Telnet

Hi there,
IÂve got a problem hopefully someone can help me with. I have the above mentioned AP and it is configured, working well and providing wireless access to several laptops on our domain.
The thing is I canÂt get access to the web-based interface to add new laptops Mac addresses to the AP as I currently have them secured with local list Mac address authentication but my user name and password when entered in the web browser login dialog box wonÂt allow me in although strangely it does allow me to login using the same credentials when I telnet into the AP.
Does anyone know why I canÂt get logged in using the web interface even though the user name and password does appear to be correct as I can telnet in? Also if you have any suggestions how I could sort this without having to perform the password recovery procedure, as I donÂt want all the config on the AP wiped and want to avoid having the set the whole thing up again.
As I workaround if anyone knows what the commands are to allow me to add the Mac addresses of the new laptops so they are added to the local list Mac address authentication list so the new laptops are secured that would be great.
Thanks in anticipation,
Tony

Your AP is probably configured to use the enable secret as the password. Try entering nothing for the username, and enter your enable secret for the password ('Cisco' by default).
If that doesn't work, post your running-config and we'll be able to see why it's doing that. It's a standard configuration, and no worries because wiping the AP won't be necessary since you can successfully Telnet in.

Access Point configuration for flat network

We have recently aquired a remote location which has a pre-existing flat network (172.16.X.X/16). Before we are able to convert them over to our new IP scheme, they have a need to have wireless connectivity on site. We have 4 1142's which I need to configure for them. I have experience configuring WLC's and autonomous AP's for networks with multiple vlans but have never configured AP's for a flat, single subnet network. I need to configure them for either guest access (internet only) or corporate access to network resources with radius authentication. Do I configure a native vlan as I would for a typical multi vlan network? Do I configure the switch port as an access port as opposed to a trunk beacause of the lack of layer 3? I basically need a sample configuration for this situation.

since you are on flat network, you just need to configure the SSID, no need for subinterfaces. With the AP only servicing the one VLAN you can leave the port as an access port as well.
as they are on the only subnet, I wouldn't do a 'guest' SSID. I would go with just the corporate SSID with WPA2/AES/802.1x. So the config is exactly the same for the RADIUS server and the SSID, but greatly simplified since you don't have to sub-interface anything.

WLAN access point "missing" when connection alread...

Hello,
I have an E63 with version 400.21.013 firmware. However, I have experienced this problem from day one. I do not have a data plan but I use WLAN at various locations, and there is a list of access points in the Settings.
I have a home access point configured with WPA2 and I have all the settings saved in the Connection Manager (or is it WLAN Wizard - I don't know). When the phone is not connected to any AP and I use a program that wants data, it will almost always show the "Home" AP in the list which appears right after "Searching for available access points" is briefly displayed. "Home" shows up right below Search for WLAN. There is no problem making the first connection.
However, if the "Home" AP is already in use and I open another program that wants data, at times it will not show my Home AP in the list. If "Searching for available access points" is only displayed for a split second, "Home" will not be in the list. Sometimes I can close the program and open it again and if "Searching for available access points" stays on screen for about a second, then "Home" will be on the list and I can connect. Sometimes I will have to try 3, 4, 5 times, and sometimes it will never "see" the AP unless I disconnect the WLAN and start all over.
Right at this moment, there is no problem. I can open program after program and connect via my "Home" AP. But it is frustrating when it does happen. Has anyone seen this or found a remedy?
Thanks.

Have you tried changing the WLAN channel (i.e. frequency) of your home WLAN access point / router?
Try switching between few different channels (like 1, 3, 6, 9, 11) to see if some channel happens to work more reliably. It is possible that there is some radio interference (neighbouring WLAN networks, cordless phones, Bluetooth devices etc.) on the currently used WLAN channel, causing phone to discover this network less reliably.
In case your WLAN access point / router includes 802.11n support, make sure that your AP's "channel width" is set to a standard 20MHz mode (instead 20/40MHz).
This is a bit long shot suggestion (just guessing), but if switching the WLAN channel related setting on the AP doesn't help then you could also try editing your phone's access point (the one created for you home WLAN network, under Tools -> Settings -> Connection -> Access Points) so that your phone should consider this particular WLAN network as an "Hidden SSID" (even if network really isn't hidden) by changing the "Network status" setting from Public to Hidden.

Compatible with Netgear Access point?

I plan to operate some wireless G security cameras with a netgear WG102 Access point with their optional 2.4 GHZ outdoor antena. I will also purchase a new airport extreme and a usb hub to share a printer a external drive from lacie.
Plan to hook the extreme to the access point via a crossover cable and the external antena will reach all the cameras up to 500 feet away.
Has anyone tried this and can the access point setup with the extreme?
I really wish the extreme had a optional external omni directional 9 dbi antena.

Your speed problems might not be problems at all. It might be due to the specifications of your access points. A normal G router runs 54 mbps wirelessly and a B access point runs at 11 mbps wirelessly.
And the brand new PC... where is it closest to? To the Netgear or the Linksys?

Can't HP Officejet pro 8100 do wifi access point?

Yesterday my HP Officejet pro 8100 arrived and I try to connect via wifi. I thinked that It need a infrastructure access point to print via wifi.
When I powered on the printer I osserved that It create an access point autonomously with SSID: HP-Setup-7A-Officejet Pro, with IPv4 address server, etc...
I was very happy and I printed a page with my smartphone samsung s4 connected directly with printer access point (not wifi direct but standard wifi).
Today no changed occurred but I can't use printer with its own access point, but only with an external wifi access point.
Someone can help me, please? It could be an hardware problem?
Thanks,
Luca
P.S. in web server I checked that "access point connectivity" (Punto di accesso wireless connettività in Italian) is checked.
This question was solved.

Hello lucait
To print via WiFi you need to have a wireless router setup. Once you have the wireless router setup correctly you will have a SSID and Wepkey that will enable you to add devices to your network. The network will allow all your devices to communicate not just with each other but with the internet. At the moment your printer was not put in a network so instead of broadcasting on a network it is broadcasting on it's own network called HP-Setup-7A-Officejet Pro which is only good for a short period of time to allow you to setup your wireless. I am going to assume you have a wireless network and you are just needing assistance getting the printer setup on that network.
To set your printer up on a network you will need to reset your network defaults so your printer begins to broadcast that HP-Setup-7A-Officejet Pro network again. You can do this buy following the steps on the HP Support document Resetting the Network Settings. Once you have done this you can begin to install the software that came with your printer on your computer. You want to set the printer up wirelessly when the option arrives. The software should configure your printers wireless for you and put it on the network. Once completed you should be able to access your printer from all your devices as long as they are on the network.
I hope this helps resolve your wireless issue. Thank you for posting on the HP Forums. Have a great day!
