Cisco Wireless :: Are There Multiple Models Of AP541N
Nov 6, 2011
We are considering order the AP541N for our network. A few questions...
1). Are there multiple models of the AP541N? or just one cisco part number?
2). I am assuming the basic antenna comes with it. If this is something that I need to buy seperate.
3). Are there part numbers for the POE injector? Need to know part numbers on the AP541N and the poe injectors?
4). We would buy a couple of these and run them in cluster mode. My understanding is that I won't need a controller. Do I need to buy a certain model to use the clustering or is that available on all the AP541N?
5). Can I have this talk to active directory to authenticate users? Is that tough to do? Do I need install some kind of agent on a domain controller? I have configured the ASA to use Active Directory for authentications. Should it be any more difficult that that?
I have setup a few other Cisco APs before and am generally familair with wireless. But, I am not a "wireless expert" and don't have any experience with this particular product.

A couple of questions about the AP541N:
1. How to get these installed and working properly, especially in a clustered environment? I have read so many comments about slow performance, no performace, bad coverage, etc... They sound like the perfect product for my intended use if they actually work as advertised.
2. what is the installation requirements for multiple units? (What is the minimum/maximum distance between units? How many units are needed for a certain area?

I have one AP541N and need to extend the wireless network with a second wireless AP. Which models of AP can I use with the AP541N to achieve a 'cluster', please? Is it just with a second AP541N or can I use other Cisco APs to achieve the cluster?
Am I correct in thinking that doing this will allow wireless clients to 'roam' seamlessly between the two APs?

I am able to view clients, rogue APs, rogue clients etc, but the information is faily inaccurate. Thus, I am trying to calibrate using the RF calibration models. I have created a new model and am attempting to add data points.After adding the client MAC, selecting the floor plan and clicking next, the floor plan loads and a message pops up stating: "Could not enable S60 across all relevant controllers on this floor". I click OK, and select "point" as the calibration method. When I place the calibration point on the map and click GO I am presented with the following message: "Failed to initiate data collection. Please make sure your client is connected on the wireless network and then try again." Both of these messages can be seen in the attached screenshots.
I have confirmed that the client is associated to an AP located on the map.I have confirmed connectivity of the client.I have used both the Cisco AIR-CB21AG-W-K9 (CCX V5) and the integrated intel wireless card (CCX V4).I am running WCS 7.0.172.0, MSE 7.0.201.204, and WLC 7.0.116.0.

I'm adding some additional AP's (3502s) to an environment that is all 1131AG AP's. The DHCP is configured for DHCP option 43 for remote sites for layer 3 discovery. Since only one AP mode can use option 43, I've added a DNS entry for cisco-lwapp-controller in my local domain.My assumption here is that the new 3502's will be able to use DNS for discovery, while any additional 1131AG would continue to use DHCP option 43. will this work in a mixed environment?The new AP briefly showed up on my controller, but then disappeared. The LED is cycling red, green, off - indicating it is still in the discovery process. Could I effectively remove the option 43 in DHCP and have all AP's use DNS? Is this as reliable as option 43? What is the best practice for discovery?

We are looking at doing some switch replacement. These switches will be in for ~7 years.We need POE for a VOIP phone system, and 10gb uplinks back to the core. We want to have the ability to go POE+ in the future.
We were quoted from our vendor for:WS-C3850-48P-S with 2x715w Power supplies. It looks like the data sheet says that to get POE+ you need 2x1100w or 1x1100w & 1x715w. Do we need to step up to the WS-C3850-48PF-S?

We have acquired few AIR-BR1410A-A-K9 AP's that are for US only. I am in Pakistan. For our market, Cisco proposed AIR-BR1410A-E-K9. This is fine as it is listed on their website as well.However, since we also have the "A" model and now the "E" model, can we place an A model on one end and an E model on the other and make them communicate with each other?

I am planning to build a site to site vpn tunnel, connecting 2-3 satellite office to the main office.After searching the product, I really don't understand the difference between models like the ASA5505 and RV042.Can I need to use ASA5505 in the main office while RV042 in the stallite offices? Or can I use RV042 (or upper) in all the office and it is enough for vpn tunnel?If it is the case, what is the benefit of ASA series over the RV series?

ACE 4710 deployment model. We'll be doing an eval later in the year, but I'm just looking to understand the architecture.We have a stack of 3750 switches with a single VLAN (10.1.1.0/24). Connected to that stack is a pair of web servers (10.1.1.5 and 6) that we want to provide load balancing/failover for. Some of the clients are located right there on that same VLAN. Other clients may be coming from other spots in the infrastructure.It sounds like I could put a pair of 4710s connected to that stack of switches, in a single arm deployment? And then the virtual IP and the real servers would all be 10.1.1.0/24. Maybe use an etherchanel to connect each 4710 to two 3750s?

I am trying to decipher the differences between the two models of the 1921 router. One has an IP Base IOS and the other has a Security IOS. I have an ASA so I don't think I need all the Security IOS bells and whistles on an internal router. Although, does the IP Base IOS allow for trunking and sub interfaces? I definitely need that and on CDW's website it says that the 1921-Sec/K9 w/ Security IOS includes 802.1Q and that spec is not listed on the 1921/K9 IP Base IOS model.

I just installed a brand new AP541N-A-K9 (running AP541N-K9-2.0(1) software) and cannot seem to add a SSID. I've tried both from CCA and directly from the Web interface (Wireless:Wireless Network Setup menu). The Add Another button doesn't seem to do anything. I've even tried multiple browser versions.

I have 2 AP541N access points. Have been working well for a couple of years. Later last year they just dissapeard from CCA one day. COundt access them but they were still delivering 'wireless' so to speak I have recently put them back to defaults to try and get them back in to CCA. i had one, but not the other. They would work fine via GUI/web access.Then i updated them to 2.0.4 (both images) and since doing that i have no access to either of them via any form.

I mistakenly mis-configured "Management ACL mode" on my AP541N.
Administration>Administration Access Control>Managment ACL Mode
I set this to "Enabled", the problem is I only entered 1 IP address, and that IP address is the SAME IP as the AP's own internal interface. I was not thinking and entered that IP out of habit when I meant to enter my workstation's IP. The FW does not have a safeguard against this.
So, as you can see, this is a big problem, because now I have completely cut off all access (That I can think of) to the router. I can never access the AP as that IP because if I set my workstation to that IP, 1) There will be an address conflict, 2) My computer won't route traffic to the AP out its NIC because it recognizes that IP as itself.

As I posted about in the other AP541N thread about degraded performance, mine did a strange client disconnect last week. It dropped all authenticated clients, but they all thought they were still connected. A quick disable/enable of the wireless card on the laptop would get the computer back on the AP.
This same thing happened again today.
Device information and configuration:
Device: AP541N
H/W: V01

we have two AP541n APs that were clustered togehter. They are powered using PoE. The other day I discovered one of them wasn't working properly. I couldn't log into it from the web interface so I unplugged it and plugged it back in from the PoE switch. That didn't work. Since then I have taken it off the network and have tried to reset it and I still can't access it. I've tried connecting to it from the default IP, which according to the admin guide is 192.168.10.10, and that doesn't work. I have tried using Telnet and SSH to connect to it using the default IP and the static IP we had set for it. I have set up a little linksys router and plugged the AP and a laptop into it in hopes it might get DHCP, but that hasn't worked either. I have also noticed the WLAN 2.4G and WLAN 5G lights are not coming on. The PWR, SPEED, and LAN lights all come on. The DIAG light comes on when it's furst plugged in and then turns off. Right now it is not plugged into PoE so that light is off too. We had both APs plugged into an ESW-520 that was plugged into a UC560 which had recently been updated to the latest firmware: 8.6.1. The short story is I don't have any connectivity to my AP541n, even after being reset. No wireless, no Web GUI, no ping, nothing. Has this thing become a large paperweight?

I purchased quite a few of these APs as they listed the ability to function in WPA2-PSK mode, but on initial configuration I see that this may only apply to standard AP mode? Is there any way to configure WPA2-PSK on an AP541 to AP541 bridge? Unfortunately, this is a must have for our client. If not, what would allow for this with an external antenna port?

I have 2 AP541N's set up using a WDS bridge, broadcasting a single SSID. I am using WPA-PSK for the bridge and WPA/ WPA2 and CCMP (AES) on the SSID. I only have around 75 (Mac, PC, iPad, iPhone and Android) devices that use wireless. Some are laptops that roam around from AP to AP, and are using LAN when they are not roaming. I have increased the roaming agressiveness on PC clients and this doesn't seem to have resolved the weak connection. At most, I have 50 clients trying to access the wireless at one time. My problem is that they keep on dropping the connections and have real problems reconnecting once it's dropped. After 4 or 5 tries, they may or not be able to reconnect.

when moving throughout our building my laptop will not switch between AP’s unless it loses its connection with its existing AP then it will see the other AP that is closer and connect to it.
For example, I start at one end of the building where it connects to AP#1 at 270Mbps, if I then slowly go to another section of the building, the speed will drop all the way down to 24Mbps, but it will not switch over to AP#2 unless I turn off AP#1 then the laptop instantly switches to AP#2 at 160Mbps. Again the same behavior if I start walking back the other direction. The laptop will not disconnect from AP#2 until the signal is lost.
With my 2.4GHz wireless 802.11g AP’s (WAP200) I can roam around the building and the laptop will happily jump between AP’s always staying with the faster of the two available.
Settings are all pretty basic.
Mode is set to 5GHz 802.11n Channel is set to AutoA single SSID is running WPA Personal using wpa2, CCMP (AES)Channel is set to AutoChannel Bandwidth is set to 40MHzClustering is enabled and the AP’s see each other just fine.

I recently attempted to update my access points Software from AP541N-K9_1.8(0) to AP541N-K9_1.9(2). As soon as the update and reboot were complete I could no longer connect to the wireless network using my iphone. I switched back to the secondary 1.8 software and could immediately reconnect my iphone to the network. Upgrading to 1.9(2) changes a setting or is flawed.

I was looking for some clarification on the capabilities of these devices to allow roaming of clients between AP's. Take a basic scenario of 3 AP's and a single SSID. I know the AP541N has clustering which uses the Fast Client Roaming Protocol, which basically does a quick re-connect to the new AP. Not quite as seamless as using aironet and a controller, but still pretty good.
Question 1 How does the WAP321 handle roaming? Obviously without the clustering feature you would have to configure each AP independently. But after setting them up, would it support roaming in a similiar way to the AP541N??
Question 2 Would running three standalone Aironet 1141's operate any differently in terms of roaming?
In summary I like the roaming capability of the AP541N but hate the large clunky form factor. I need something that can be mounted in an office environment (ceilings) that will handle easy client roaming. A short disconnect isn't a concern as long as it reconnects on it's own. Wireless controllers are a little out of the price range for this setup.

i have a 541N running the latest firmware 2.0.2.It has 3 SSIDs for the 3 vlans that it has.I have configured b/g/n.The power is fullIt is powered via POE.The end customer tells me that the range it covers is very very small!Comparing to traditional low budget APs the power is very very low.It does not cover 30-40m in free space where other APs do.Do i need to configure something more in the radio settings?

trying to get my new router and bridge to work I am close to give up.
1. I have bought a RV220W router this will be connected to Internett and all wireless devices will connect to it. It seems to work fine. I have enabled on AP profile where others easyli can access internett through router WAN port
2. I have bought a AP541 Access point that i want to have as a bridge (We earlier used 3COM without problems) Some Computers and other stuff like printers will be connected to this through a switch for the Ethernet port on AP541. (I dont want any clients to connect wireless to AP541N)
Before I start asking detailed questions, i want to verify that my setup is possible. Reading the Information on the shops webpage clearly states that AP541N can work in bridge mode, but struggling to find any good explenation makes me wonder if this really is true.
Can Cisco AP541N works as a bridge together with RV220W.

I have an SA520W firewall, and am implementing a new AP541N. On the SA I am using port 4 to connect the AP. Trunking is on with Vlan 1 and 25. Connecting the AP I am able to use VLAN1, however when I assign a new VAP using Vlan 25, I only receive IP addresses for VLAN1.

I have an AP541N-N-K9 Dual Band Access Point which I'm having some issues with. We have a few users with Android and iOS devices and they want to connect to our corporate network but when we configure the wireless network details in both OSs none of the devices get an IP address. We have an MS AD/DNS/DHCP infrastructure. On looking at the logs of the access point I can see the devices successfully authnticating but then I see the connection being disassociated and deauthed. A few seconds later the device attempts to get an IP address again and the same thing happens again. This loop just keeps on going forever. If we connect to the AP with an MS OS everything is fine.
