Cisco Wireless :: AP541N Device Stops Accepting Client Connections

Feb 8, 2010

We have an AP541N that has been deployed to replace a Cisco 1200 AP (B/G radio).  The 1200 functioned perfectly in our environment.  The new AP541N on the other hand seems to work fine right after a reboot but immediately starts to degrade service.  Over a short period of time, the devices bandwidth degrades to the point were the wireless network is not usable.  This happens with just one device connected.  Eventually, the device stops accepting client connections. We are unable to get any relevant logging out of the device to diagnose the problem.

Linksys Wireless Adapters :: WMP600N - System FW Not Include Enough Info To Properly Configure / Use This Device

May 4, 2010

I've purchased a wmp600n pci adapter january this year and installed it with no problems and did not encoutner a single problem with it until today. I use windows 7 64bit.
 
I've just came back from a 3 week absence and turned on my computer for the first time since i left. I notice that I have no wireless connection. So i go to network connections and realize that my wireless adapter dosent even show up..only my lan card. So i check my device manager, and under network adapters, i can see my wireless adapter, but with an exclamation mark next to it. I check the properties, and under the status box, it gives me this message.Your computer's system firmware does not include enough information to properly configure and use this device. To use this device, contact your computer manufacturer to obtain a firmware or BIOS update. (Code 35).
 
So i do what it says, and flash my bios to the latest version. After the update, I check the device manager, and the error message is still there. I check my wireless adapter driver version and it is v3.0.2, which is the latest version according to the linksys driver download webpage. I've tried uninstalling and re-installing the adapter but no luck there. I also checked to see if maybe there was a problem with my pci slot and that was not the problem because I was able to use my older wireless adapter.

D-Link DIR-655 :: Devices Connected Not Showing In Device Info List

Apr 26, 2011

I just got a DIR-655 and set it all up pretty easily. I have 6 wired and 3 wireless. All work fine and all are set to use DHCP. But if I go (in the router) to the Lan Computers list under Device Info, three devices (2 wired, 1 wireless) do not appear. I do have a switch added to the system, but of the three devices connected to it, 1 shows in th Lan Computers list and the other 2 do not.Since everything works, I'm mostly just curious why this is. Every previous router I've had showed everything correctly.

Cisco Wireless :: 4402 WLC Web Interface Missing Buttons When Logged Through Radius?

Feb 12, 2012

I have a Cisco 4402-25 WLC with the below information that is having an interesting issue. When you log into the GUI interface with the local account and click on WIRELESS, then choose a accesspoint it brings up a menu where you have three buttons below for the following options (Hardware Reset - Reset AP Now), (Set to Factory Defaults - Clear All Config), and (Set to Factory Defaults - Clear Config Except Static IP). The problem I am having is we access all of our WLC's using Radius and when you enter your AD username and password and go to bounce a access point the GUI interface is missing the buttons, they however appear fine when logged in with the local account.

Cisco :: High CPU In 2960 When Not Logged

Aug 28, 2012

I've noticed a strange behaviour in my 2960s regarded to CPU.
 
CPU level is very high, 70-75% when nobody is logged by vty or console, but it drops drastically to 40% when sombebody logs in. I've been able to discover that this is due to CPU interrupt level, as it shows the output of sh process cpu sort 5sec, just logged in.
 
RH0A01-SW1-10G#sh proces cpu sorted 5sec
CPU utilization for five seconds: 68%/37%; one minute: 67%; five minutes: 50%
 
...Some seconds after logged in...

I just bought the Dir-655 with 2.00 firmware. I am having trouble with my NAT on my game system and I have tried everything but I have everything setup on my router where it needs to be. I read somewhere, where a guy was having my same trouble and he upgraded his firmware to 2.03na. I have tried with no success whatsoever.

Downloading the file from the d-link website with no problems. But i keep getting the same message when i try to upgrade the router saying the file may be corrupt, the router is to busy, or I am not logged in as an Admin. I am the only one using the internet and I am logged into my router as the admin. it wont even start uploading the firmware to my router..

Cisco Wireless :: 1142 AP Showing Maximum Of Only 54mbps In Network Info Dialogue Box

Mar 18, 2013

I have encountering a problem with a new installation at my clients side recently.We have a 5508 wlc and a bunch of Laps connected to it.Recently we associated a 1142ap to the same controller.The issue we are facing is that , the client laptops that are connected to THIS ap are showing maximum of only 54mbps in their network information dialogue box.Initially i couldn't understand why this could happen.But after a bit of research , i came to know that this could happen because of ``unticked`` data rates in the controller , or because of not using wpa2 with aes as the security standard for N-series access points.Now i have enabled all data rates in the High Throughput section as well as enabled the correct encryption standard.But still the issue persists.We have checked with multiple laptops , to rule out the possibility of a faulty n/w card

Cisco Wireless :: AP541N - No Access Or IP Address

Feb 12, 2013

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.

Cisco Wireless :: Misconfiguration Of Management ACL On AP541N-A-K9

Nov 20, 2012

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.

Cisco Wireless :: AP541N Drops All Clients?

Jun 20, 2010

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.

Cisco Wireless :: AP541N Connectivity And Web Management

Apr 18, 2013

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?

Cisco Wireless :: AP541N Bridge With WPA2

Aug 23, 2010

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?

Cisco Wireless :: AP541N Keeps Dropping Connections

Mar 6, 2013

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.

Cisco Wireless :: AP541N - Computer Not Switching Between AP's

Jan 4, 2011

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.

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.

Cisco Wireless :: AP541N-K9-1.9(2) Won't Work With IPhone 3gs

Cisco Wireless :: Difference Between WAP321 And AP541N?

May 21, 2012

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.

Cisco Wireless :: Using AP541N As A Bridge With RV220W

Sep 25, 2011

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.

Cisco Wireless :: AP541N Can't Get AIP Address On Some Devices

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.
