Mesh Network using 1522

Hi,
I am newbie to Wirelss Networking.
I want to build a network for Data, Voice & Video applications. But I get to know that I should not go beyond 24 Mbps (recommended) backhaul. Is that enough for these three applications. I have 1 RAP and 8 MAPs in radius of 600 feet. approximate users would be 2500.
Please sugeest.

Hi,
We have an outdoor wireless installation coming up for a public park using 1522. Can you please share the RAP to MAP distances used in your deployment ? For 802.11b/g, will a client to AP distance of 100m give good performance ? will the clients be able to communicate properly at such distances ? Also what approach did you chose to divide the outdoor area and decide on RAP and MAP placements ? Appreciate any suggestions from your experiences.
regards
Joe

1522 AP fail to join Mesh network

I have a Mesh network with 1522 AP's in it. The RAP and on other AP have joined but 4 other AP's get the below error while trying to authenticate.
AAA Authentication Failure for UserName:c1520-(mac address) User Type: WLAN USER
I have added thier MAC's to the MAC Filtering section on the WLC but they just keep failing. Looks like they are authenticating with the c1520 added onto the MAC everytime. The first PAP tried to authenticate like that then it switched to the MAC address only.
What am I missing? Thanks for the help.

Hi,
Try changing your mesh authentication type from eap to psk.
for some odd reason I've seen changing that correct issues like this.
can you provide the output of 'show mesh config' ?
thanks

Dual RAP Mesh Network vs PTP Wireless Ethernet Bridging to provide link redundancy

Currently looking at a few options to optimize a current point-to-point wireless LAN-to-LAN connectivity shot for a wired customer site for better redundancy (hardware diversity and/or logical path diversity). Currently the customer is fed via an older solution, using two Cisco 1522 APs with Cisco Aironet 14-dBi Path Antennas (AIR-ANT5114P-N) for a 5-GHz PTP wireless ethernet bridge (under 3km), in which one 1552AP hangs off a L3/L2 Distro switch and the customer's 1522AP hangs off a 3750X switch, which has another access switch hanging off it via a fiber run of about 2km, which is exposed in parts and can't be re-run again due some limitations.The customer doesn't utilize any wireless services. Due to their location, we can't connect them to our wired distro infrastructure directly via fiber.
Looking at setting up two wireless shots (instead of just one currently used); 5-GHz point-to-point bridges using upgraded gear: Cisco 1552EU APs with Cisco Aironet 14-dBi Path Antennas (AIR-ANT5114P2M-N) or straight Exalt r5005 solution. The PTP shot will hang off two seperate distro switches for redundancy purposes, pointing toward the customer site at two seperate locations, spaced apart by approximately 1 to 1.5 km, so that they aren't at the mercy of being isolated on one side if they have another fiber cut which connects their two main access switches together. If need be, we can hang two main APs on one distro facing two APs at the customer site, since this would create some redundancy, just not the same level as above.
The below is what I'm really unsure on.
Possibly looking at setting up a mesh network using Cisco 1552E APs with 2.4 GHz Omni-directional antennas (either a 2.4/5GHz Terrawave MIMO Omnidirectional antenna or Cisco AIR-ANT2547V-N antennas, which ever is best) with two RAPs, one RAP hanging off one distro and the other RAP hanging off another distro for hardware diversity, both under the same bridge group name and both RAPs hanging off the same WLAN management SVI subnet on the distros. The customer site will have two 1552E MAPs located at two seperate sites, as pointed out above. I don't think a third AP would be needed, since they don't use wireless services. Since there would be only two RAPs, not three, would it be best two set-up this with both RAPs on the same channel to minimize convergence time should the mesh transfer from one RAP to the other RAP, as long as both RAPs are spaced apart under ???? distance to avoid interference/other issues? Looking at some documenation, it appears you can have a MESH network, as long as your MAPs and RAPs fall within a 2 mile range area, preferably closer to a 1 mile range area (for better bandwidth & reliability). This solution has been brought up as possible dual-homed solution in theory, by virtue of having two more more MESH APs fall within the range listed above, to the RAPs. From a layer 3 perspective, I'm not sure what the most optimal idea to run with in this scenario set-up would be. Possibly set-up two seperate user SVI VLANs (for their data services), one placed on each access switches these MAPs will hang off at the customer site, & using the same management SVI subnets as the RAPs for the wireless managment side (for accessing the APs). From my understanding, the user data SVI doesn't matter from the perspective of when the mesh transfers from one RAP to another, it should be transparent to them. The distro switches will just have the management SVIs placed on them for the RAPs, the user SVIs will be placed local on the access switches only. And all APs will hang off access ports set to the management VLAN ID.
In my opinion, the PTP 5-GHz, dual distro homed solution makes the most since for wired client access, but since the latter option was brought up, it has to be weighed - plus I'm curious if it can work.

The Exalt r5005 works great for redundancy PTP links. You have to use the sync cable between the two co-located bridges and also set the polarization on the bridges. You can then use routing or spanning tree to decide traffic path. With mesh, you will have to make sure you set the parent or else the maps will keep switching perhaps.

Mesh networking

Equipments being used:
1) Cisco 2106 WLAN controller
2) Cisco 1131AG access points (LWAPP mode)
3) Cisco catalyst 2950 switch
Hi,
My setup is as follows:
My access point is registered with the WLAN controller via the switch. When i try to change the mode of the access point to bridge. It does not accept the change. My aim is to create a mesh network using 1131AG access points.So my question is:
Can I setup a mesh network using Cisco 1131AG access point in LWAPP mode or do i need to change them to autonomous mode?
Any documentations or comments will be helpful.
Thanks in advance.
Regards
Sri

You should be able to setup the 1130 at a Enterprise Wireless Mesh. Take a look at this link for the F&A for Enterprise Wireless Mesh:

Blacklisted AP in mesh network?

What is the best way to debug a 1522 AP which has blacklisted its preferred mesh network path back to the root access point and will instead use a very poor path? I seem to find a lot of info on blacklisted clients but not on AP's?

The best to refer is the check the Traplogs that is generated on the controller. Refer to the URL http://www.cisco.com/en/US/docs/wireless/access_point/1500/troubleshooting/guide/TrbleshtMesh.html#wp1014809 for more information.

How to setup a wifi mesh network in a 6 story full brick home

Hi,
We have to create a solid wifi mesh network in a 6 story multi mil $ home. The home will have complete home automation and requires wifi crestron touch sceens to utilise the network and also all the IT hardware. There will be the ability to run cables to all access points however I am looking to build a power over ethernet mesh secure solution with also an external access point that will never break down or drop out. Each floor has more concrete then you can imagine however the floor span is no more then 30 meters with little walls. If we can create a vlan for crestron control systems then this will be the ideal situation. Your help is very much appricated with recommending a best solution.
Regards - Jay

Mr Davis has it pretty much nailed.
There are so many potential gotchas, depending on the front-end choices, there is no way (none, zip , nada, bupkis ...)to do this without (at least) one comprehensive survey by a real pro. If you talk to anyone that says this will be easy, say "thanks" then show them the door.
As an example, if you decided to go with 802.11g (2.4G), you get three channels total that won't overlap (1, 6, 11). Overlap will kill performance as it is seen as interference.
You will need to break the floorspace into "cells" such that no two adjacent cells will have the same channel assignments, but overlap enough to permit seamless roaming for things like VoIP.
In addition to the lateral cell structure, you may (site survey will determine) also have to consider the vertical, such that two cells on the same channel do not see each other through the floor, or by reflection up the stairwell or elevator shaft.
Adjusting the cell shape and diameter is done by changing the type of antenna (omni, sector, panel ...)and the power to each antenna.
The central controller system supports an "automatic" mode that theoretically could figure out these adjustments dynamically (within the propagation physic permitted by the antennas and environment) ... but auto modes are best used to maintain the operational design when things get dynanmic (like people walking around, pasing interference, passing Bluetooth, leaky microwave ovens ...)
This is just ONE very small piece of figuring all this stuff out. You need experienced eyes and equipment on-site, probably for a couple days depending on the ultimate application suite you decide to implement.
A VLAN for the touchscreen / control system is trivial (and common) compared to the other site engineering.
Good Luck, it sounds like a really cool & fun project.

Can I assign some SSIDs to some specific APs in the mesh network?

Hi All,
We are thinking about putting a mesh network in the site. But some wireless client only work at some specific area and they are not moving around. So I want to limit that ssid only at that area. So I wonder whether I can assign that ssid to 1 or 2 access points in that area. The other aps don't have that ssid configured. Can I do this in WLC?
Thanks a lot!

Prime Infrastructure with Mesh Networks

My customer has a Mesh network at a sea port. They have about 15 mesh access points at each location with two controllers each. Would Prime Infrastructure work with a mesh deployment? There is a lot of interference and sometimes the performance of the network is affected. I want to use the WCS portion of Prime, to manage the mesh coverage, parent/child relationship between the RAP's and MAP's.
Please let me know if Prime is something I can suggest to my customer to ease the management of the mesh network.
Thanks,
Scott

Hi Scott
Prime is the replacement for wcs. Wcs isn't supported past code 7.0.

Mesh network in overcrowded channels

Hi,
I have a mesh network consisting of about 30 MAPs and 10 RAPs(1552E), which are controlled by a 5508. The area which needs to be covered is mainly consisting of tents.
The problem is, this area is overcrowded by access points which interfere with our system. Clients complain about getting disconnected and having problems to receive an ip address, especially during the evening hours.
The APs show a channel utilization of 80-100% in the 2,4gh spectrum(no wonder with all those rogue aps). It's not that bad in the 5ghz spectrum, which is why I activated backhaul user access. The connection got better but it's still far from beeing stable.
Is there anything I can do except for unplugging the rogue access points? I know that it's hard to communicate if the channels are on their maximum, but maybe there is a way to improve it
Cheers

Hi Martin,
Maybe using indoor mesh APs inside the tents.
I guess the APs have a higher receive sensitivity than the usual weak clients like phones or tablets.
This will result in a more crowded wireless environment in the 2,4 GHz band for everybody else - but who cares as long as it works

*wireless mesh networking*

can a wireless mesh networking application be built using the sun java wireless toolkit??if yes ...then plz tell me how to do it..

The distance at 54 Mbps for 2.4 GHz side of the mesh (client access) is basically the same distance as it would be with most 2.4 GHz Access Points.
That said the "indoor range" being 90-100 Ft and outdoors being further because there are no obstructions. Now the Cisco Aironet 1500 does have an amplifier and a higher gain 2.4 GHz antenna enabling it to transmit further but how far that goes at 54 Mbps depends on the client being used (and the Access Point's ability to hear same).
remember just because the Access Point is improved (the client is typically operating at lower power and in some cases with an internal antenna so distance it really a matter of the client used and the environment it is used in. So there is no real exact answer as it varies but I'd expect to get at least 140 Ft or more outdoors at 54 Mbps. Again, you'd really have to test it with your specific client in your environment more more accurate numbers.

Is there a way to create a virtual network using C# and the Azure SDK/API?

I don't see a clear way to create an Azure Virtual Network using the SDK.
I have all the methods to create the virtual network configuration, but no way to submit it:

VirtualNetworkAddressPrefixes.Add("a.b.c.d/cidr");
DNSServers.Add(new NetworkListResponse.DnsServer() { Name = "TestDNS1", Address = "a.b.c.d" });
Subnets.Add(new NetworkListResponse.Subnet() { Name = "Subnet-1", AddressPrefix = "a.b.c.d/cidr" });

I have also created the entire XML response and sent it to the NetworkManagementClient -> Networks.SetConfiguration() method, but it appears this command expects the virtual network to already be in existence. If anyone could give guidance, it would be
appreciated.

Hi,
As discuss above , we have to create the XML response ,before that first you have to
GetConfiguration() details of existing virtual network.
string.format("@<NetworkConfiguration xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns='http://schemas.microsoft.com/ServiceHosting/2011/07/NetworkConfiguration'>

How do I extend my AirPort Extreme network using airport express

How do I extend my AirPort Extreme network using airport express

see http://support.apple.com/kb/HT4145 and other support articles
and/or
https://discussions.apple.com/thread/4462789?start=0&tstart=0
and many other discussions on this forum about this topic.

Can I create a unique subnetwork when extending a wireless network using Airport Extreme?

My office building has an Airport Extreme to provide wifi to our individual suites. I would like to create a sub-network using my Airport Extreme for my suite only that uses the wifi signal from our office building and provides internet to the computers (both wired and wireless) in my suite but have it protected so that other suites in my building can't see my computers. Is this possible and how do I do it? I have currently set up my Airport Extreme in wifi-mode "extending a previous wireless network" and have the router with its unique router name. But once I extended the wireless network, I could not find the network name of my router, only the office name (the one I was extending). The computers connected via ethernet to my Airport have internet access but none of my wireless computers see my airport name, it sees the office building network name. I'm assuming they are connecting to my Airport since the signal level is much higher than before and it appears that my Airport is rebroadcasting the network name of my office building. Is there a way to have my Airport broadcast its unique identifier for wifi, still connect to the internet via wifi signal to the Office building airport and maintain segregation between my computers and the rest of my office building?
Also, when I use the Airport Utility on my Iphone, I see the internet -> the office airport extreme -> and then 2 different base stations connected in a Y. Mine and my neighbors (who is probably doing the same thing as I am). But there is a dotted line to my base station, does that mean I'm connected to the internet via my neighbor's airport?
Any thoughts?

I would like to create a sub-network using my Airport Extreme for my suite only that uses the wifi signal from our office building and provides internet to the computers (both wired and wireless) in my suite but have it protected so that other suites in my building can't see my computers.
It is not possible to configure a single Apple AirPort router in this manner using wireless only, but it would be possible to do this with a single AirPort if you connect your AirPort Extreme to the "main" router using a wired Ethernet connection.
As for wireless only....you could probably do what you want by using two Apple routers....an AirPort Express to join the wireless network and provide an Ethernet signal to the AirPort Extreme's WAN port. Then the AirPort Extreme could then be configured to provide a separate network using a different subnet.
Users on the "main" network would not be able to "see" any devices on your "private" network and vice versa.
I use the two router set up all the time at hotels that only provide a wireless signal. The first Express "joins" the wireless network and feeds an Ethernet signal to the second AirPort which is configured to "create a wireless network" in router mode.
This way, I can connect multiple devices to my "private" network, but only pay the hotel for one connection since the hotel router only "sees" the AirPort Express that joins the network.

How can I set up a wi-fi network, using one time capsule and two airport express

how can I set up a wi-fi network, using one time capsule and two airport express ?
The time capsule is near the Mac. ok
The first Airport is on the corridor, ok, works well and the App on the iPad signals so, ok
But when I plug the next Airport on another room nearby nothing happens, and signals disconected ....
is the signal so weak that is not able to go to ono room to the other ?

Well, even if you have the first express set up to extend the network, the second express can only extend from the TimeCapsule.
Maybe you got walls of sheetrook in the way, or kitchen/bathroom tiles, etc, dampening the signal rapidly.

Cannot extend my network using AirPort Express

I just purchased a Time Capsule (2TB) and replaced my Airport Express WiFi. My intention was to expand my network, using the AirPort Express to expand the Time Capsule signal. I have tried several times and cannot get it to work.
Using AirPort Utility, I set up the Time Capsule successfully, making certain the "Allow the network to be expanded" box was checked off.
After resetting my AE, I plugged it in, it was detected by AirPort Utility, and I set the AE to expand the network, using the same network name, security, and password. When I save the settings and update, the AirPort Uitility returns an error stating that the AE unit could not be located. AE unit is flashing amber (slowly).
What DID work was connecting the AE to the Time Capsule with an ethernet cable, but this is not ideal, since I want to locate the AE away from the TC and wish to do it wirelessly.
Can someone offer some helpful suggestions that will work?
(Running MacBook Pro w/ OS X 10.7.2 and AirPort Utility 5.5.3.)

I would suggest the following:
Please move the AirPort Express (AX) to the same room as the Time Capsule and perform a Factory Default Reset as follows:
Pull the AX from power
Wait a few minutes
Hold in the reset button and continue to hold it in for an additional 8-10 seconds while you simultaneously plug the AX back in to power
Release the reset button after the hold period, and allow 40-45 seconds for the AX to display a slow, blinking amber light
Temporarily, connect a spare Ethernet cable from one of the LAN <-> ports on the Time Capsule to your AX
Open AirPort Utility and click Manual Setup
Click the Base Station tab below the row of icons to name your AX, assign a device password and adjust Time Zone settings
Click the Wireless tab next to the Base Station tab and adjust your settings as follows:
Wireless Mode = Extend a wireless network
Wireless Nework Name = Same name as your Time Capsule wireless network
Enter a check mark next to Allow wirelss clients
Wireless Security = Same setting as your Time Capsule wireless network. You may need to refer to the Time Capsule settings if you are not sure what setting to use
Wireless Password = Same password as the Time Capsule wireless network
Confirm Password
Click Update to save your settings
Close AirPort Utility and disconnect the Ethernet cable as soon as you see the message that the settings have been stored successfully on the AX
Wait 40-45 seconds for the AX to restart and display a green light
You can now locate the AX where it is needed, assuming that it can receive a good wireless signal at its new location
Post back on your results
