Cisco WAP 321 causes network failure ?

Hi everybody.
I recently bought a Cisco WAP 321 for my company, but when i connect it to the network, the switch on which I connect crashes, and I lose all connectivity to the network, (internet also). i have to unplug the WAP321 and wait for a few minutes to be able to use the network again.
I'm currently using a small 8 port switch, There are usually 3 or 4 users connected on it. When I try connecting the WAP321 on another switch, only connected to 1 computer, it seems to be working : I can access the configuration page, and make some modifications.
Has anyone had this problem already ?
Any idea ?
Thanks everybody for your time !

Hi, My name is Eric Moyers. I am a Network Support Engineer in the Cisco Small Business Support Center. Thank you for using the Cisco Community Post Forums.
Could you give a little more detail about your network? What is the switch that you are connecting to? The 8 port and the other one. A network topology would be helpful as well.
Thanks

DHCP issues with Cisco WAP 321

I have 4 Cisco WAP 321's in my office connected to our Cisco 2911 ISR for DHCP, everything is fine on the office wifi on vlan 1 but vlan 3 with the guest wifi network it fails to obtain an IP address. I have tried under each of the WAPs to make sure it wasnt just the one nearest my desk. I was on the phone yesterday with Cisco about this and we turned on debugging and watched the DHCP requests and no requests even hit the ISR (only thing I have smartnet support on). I noticed our firmware was a few versions old so updated that this morning but still have the same issues so now I am turning to you all to help me figure this out.
Thanks

Cisco WAP 321 Quality Superb Worst + RMA Slow

hi Everyone, recently i notice that the WAP 321 quality is superb worst as base on project we bought 13 units of the cisco WAP 321, out of three not even use for 1 months the unit faulty (unit cannot be power UP) but adapter power is working fine.
beside the quality issues, the RMA process also very slow, when we send the unit to distributor for RMA claim, the cisco feedback the unit need to wait until November of 2015, this ridiculous, how u imagine the unit faulty the replacement unit only can send it back to you almost in 9 months time. I really can't believe it, cisco is so worst on the RMA claim.

this is the case number, we are planning to return all the cisco ap to cisco, as our end user and us really piss off with the RMA process and quality of the cisco AP. we now waiting the feedback from the ECS which is the distributor in malaysia.

Cisco WAP 321 found bug that causes loss of config

I have been setting up a WAP 321 which has been unable to retain it's settings across reboots.
What I have found is that if I leave the Timezone set to USA (Pacific) the WAP 321 can be rebooted without losing config, but as soon as I set the timezone to United Kingdom the next reboot will cause the device to take a long time to reboot and will have then gone back to factory default setings.
To help me determine if I have a faulty unit, does any one else have one they'd be willign to set to United Kingdom timezone & reboot to see if you get the same results?

Hi Tom,
It seems the exact same problem, described in diferent ways.
For me even if i configure a different management IP and after that reboot the system, the system take much time too boot and my laptop lan interface keeps goind "connected, disconnected, connected, disconnected..." until i turn off the access point off and turn it on again after about 10 seconds.
When it boots is in factory default settings.
When i'm configuring the access point on Safari Browser on a Mac laptop, i have no problem at all. I can change everything and reboot every time i want without losing my configurations.
The problem is only when i'm configuring on a windows laptop with IE9 or Google Chrome.
I will send you an e-mail with my CCOID, serial number of the access point and this description.
Note that this is the second Cisco WAP321 that we have received with the exact same symptom. We have returned the first one and received the second one with the same problem.
Best regards,
Vitor Oliveira.

Airport Express extending Time Capsule network causes network failure?

I have a 1GB Time Capsule used as my 'main' wireless access point for my home network. I purchased an Airport Express for use about halfway through across the home so that I could play iTunes music in that area... no problem. That works. However my office is also right next to the Airport Express.
So if the Airport Express is -not- plugged in I have a great signal from the Time Capsule and things work without a hitch. Once I plug the Airport Express in, every 20~30min my MacBook Pro shows I have a full-power network connection, but it wont actually do anything. I have to turn off the MacBook's wireless, then turn it back on... then again it only works for a short while. If I unplug the Airport Express this is no longer an issue. :/
So I know the Airport Express is part of the issue. But also, I know it must be setup correctly since I can go all the way to the back of the house and have a network connection [when normally without the Express I would not have a connection at all]. Clearly it's extending the network.
Any ideas why my MacBook might be getting 'stuck'? I'm relatively new to Apple gear, but long time PC user and very skilled with networking... but never experienced anything like this... but also this is the first time I've ever extended a network.
Open to any suggestions... thanks all!

Welcome to the discussion area!
Something is wrong, whether it's an incorrect setting or a defective AirPort Express because the "extend" setup normally works very well. I've gone 3-4 months with no problems at all since I added an Express last fall and the network is up 24/7.
Check to make sure that your MacBook is actually connecting to the AirPort Express (AX) as follows:
Open AirPort Utility, click on the AirPort Express and note the AirPort ID for the AX
Hold down the option key on your computer and click on the fan shaped AirPort icon at the top of the screen and you will see details about the connection. You should see the AirPort ID of the AX. If not, you are not connecting to it.
You can also check a few settings using AirPort Utility to see if the Time Capsule (TC) and AX are setup to "extend".
For the TC:
Click Manual Setup and click the Wireless tab below the icons
Wireless Mode should be "Create a wireless network"
There should be a check mark next to "Allow this network to be extended"
For the AX:
Click Manual Setup and the Wireless tab
Wireless Mode should be "extend a wireless network"
Network Name should be the name of the TC network
Check mark next to "Allow wireless clients"
Security and Password settings are the same as the TC
Is that what you see?

WAP-321, Captive Portal and Wi-FI repeaters

Hi,
So I am currently deploying a Wi-Fi Network based around Cisco WAP-321. I use the CP function with a Radius server to authentify my users. So far so good, when a user connect to one of the AP and uses his credentials, he can login and access Internet without any trouble. But I also use some Wi-Fi repeaters (Netgear WN-1000RP) to extend the range of my wireless network in places I can't install an AP. The repeaters effectively extends the range of my network, and I can connect on them without any trouble when the CP is turned off. However, when I turn on the CP, I access the login web page and enter my credentials, but no matter what, I can't login while connected on the repeater. After some research, it looks like I have to manually enter the MAC address in the MAC trough list of the AP. Except such a feature doesn't seem to exist on the WAP-321. I have tried using WDS bridge and Workgroup bridge, but without success, since I think it's only compatible with WAP-321 and WAP-121 devices.
So I am kind of running out of ideas to make this work, and I would be very grateful if someone could help me out.
Thanks in advance, do not hesitate to ask me for more informations if needed.

My name Eric Moyers. I am an Engineer in the Small Business Support Center.
I am sorry to hear that you are experiencing this issue.
While what I am fixing to share is not in any way a great solution, It can be utilized as a workaround.
With the WAP321, after trying a few different scenarios that didn’t work. I simply created two vlans, leave the Untagged vlan as main vlan and changed the Management vlan to the second. I then attached the guest SSID to the Management VLAN. This allowed me to authenticate to my guest captive portal and get an IP and get out to the internet. The Main SSID still worked normally.
Now for some caveats:
Problem: If a wireless client knows the IP of the WAP and the username and password they could get into the WAP.
Solution: Setup Management Access Control to an IP outside the DHCP scope for that VLAN and have a Strong Password.
Problem: Management of the WAP321 can only be from an IP on the Management VLAN. (In my case 2)
Solution: Setup Management Access Control to an IP outside the DHCP scope for that VLAN and have a Strong Password.
Not the very best solution, but the only workaround I can come up with for now.

WAP 321 NPS

Hi,
We want to configure a Cisco WAP 321 to NPS on windows 2008.
We have this error and we do not know what is wrong. Can you help us?.
On NPS system event viewer :
An Access-Request message was recived from RADIUS client XXXXXX with a Message-Authenticatior attribute that is not valid.
We have installed other RADIUS client on Windows 2003 Server and we have the same error.
On the Web interface of Cisco WAP only can configure the IP and password of the Radius server.
Please, can you help us?.
Thanks.

Hi,
go to your NPS/IAS, edit your RADIUS client configuration, clear the "Request messages must contain the Message-Authenticator attribute" checkbox and try again.

Stefan

Client cannot associate to WAP 321.

Dear Support Team
I have purchased, cisco wap 321 2 days back and configured it. Problems I am facing are
1. Clients are not able to connect to it. If they get connected and get an IP address from DHCP server. They have frequent disconnection.
2. User face high latency.
I would like if cisco team can take remote and resolve the issue.
Thanks
Deepak Khemani

Hello Deepak, first please try disabling the Bandwidth Utilization found under the wireless tab. If that does not resolve your problem the best thing would be to call in and open a case. At that point then one of our engineers can remote into your system and see what is going on.

WAP 321 Losing connectivity

Hi,
I installed four WAP 321 for a customer at a remote site. They are set to use a tagged VLAN 80 for management, there three additional VLANs used for SSIDs.
They have latest firmware installed.
LAN setting has untagged VLAN unchecked, 'Green Ethernet' is enabled but I think I have tried disabling it.
Connections are to trunk ports on 3560 with native VLAN 1.
WPAs are in single-point access mode.
All seems to work, but after a period of time, I would guess about 5-6 hours, the WAPs start losing connectivity to the wired ports, I cant ping them and there is no entry on the switchport MAC address table. Sometime I see ARP entries for both VLAN 80 and VLAN 1 (not used).
The only way I can regain connectivity to these devices is to shut the switchports for a while (count to 20;-) then re-enable which I presume hard boots the device.
I haven't been able to verify yet but I suspect these devices are losing all connectivity to the wired network.
I really need a resolution for this, so any help gratefully received!
Regards,
Kevin.

For the sake of those that come after me .....
My WAP 321s connected for about 40 hours now so it looks like this is resolved, this looks like a bug in the 'OS/firmware - currently version 1.0.3.4
To summarise;
In 'VLAN and IPv4 Address' settings your are advised to leave the Untagged VLAN Enabled, and leave the untagged (native) VLAN and Management VLAN as 1. I haven't established if any one of these settings causes the problem, but certainly changing all three is likely to cause devices to hang within a working day.
VLAN and IPv4 Address

MAC Address:

Macbook wireless and Cisco base station causes kernel panics

So my company uses Macbooks and Cisco wireless base stations. For some reason, when they use bother ethernet, and the wireless, the Macbook will kernel panic for no apparent reason. So since we have a fast wired network, I have been advising those Macbook users to turn off wireless and use the wired network. Wouldn't you know, the kernel panics go away. Is anyone aware of an issue with the wireless chipset in the Macbooks and the wireless chipsets in the Ciscos not liking to play with one another? I know it's the wireless in the Macbooks as if I use any other wireless base station from Apple or Linksys, the issue is not there. I should also mention that when people use those Macbooks on the wireless every once in a while, they get an access control list error. We do not have ACLs for our wireless. Our PowerBooks and iBooks do not exhibit any of these issues on the same network, so we know it is an issue with Intel based Macs. Any ideas?

I'm having a similar problem at college (they use Cisco equipment). On most of the campus everything is fine, but in the area near my classes (typically), wireless causes the mac to panic.
I asked at IT, and came back more confused (apparently, they use the same model WAPs throughout the college, so they couldn't see why one particular WAP would cause this. They guessed it was to do with the huge amount of traffic that particular WAP gets, with it being in the Computing department and all).

WAP 321 best practice

Hi
I've got 4 AP placed in the corners of the house.
I would like to provide the best possibilities of roaming users which will be moved in the building.
What kind of parameters I can change to set sensivity of reconnection user to another AP ?
Many times I saw that device works with AP with weak signal when available is another with much stronger signal.
Is any way to change moment when device will be reconnected ?
Is this process related to OS of the device ?
Generaly to avoid interference AP in neighborhood should work on different channels 1 6 11.
To configure WDS all AP should work on the same channel. Why ?
Is WAP 321 is salt water resist ?
Could it be install on boat ?
Of course inside of cabin but I can imagine that salty fog or steam available around can be dangerus.
Please advice if I can use this model or should chose differrent ?
Best regards
Darek

Hello Dariusz,
What kind of parameters I can change to set sensivity of reconnection user to another AP ?
Generally, the clients control which AP they want to connect at any given point of time. If you are using Windows operating system, you can set the roaming mode to aggressive where the wireless interface on the device will constantly monitor the signal strength from different Access Points in the viscinity (on the same SSID) and when it finds an AP with better signal than the current one it is attached to, it will switch the association to the new AP.

Answer is included in the link below:
http://www.intel.com/support/wireless/wlan/sb/cs-015906.htm

This is typically controlled by the Client Operating System/wireless card driver.
Generaly to avoid interference AP in neighborhood should work on different channels 1 6 11.
To configure WDS all AP should work on the same channel. Why ?
Essentially, WDS is sort of bridging/repeating across multiple Access Points without the need for a wired infrastructure to connect the access points. Since the WAP321 has a single radio interface, it cannot switch between different channels on the fly when communicating with another AP and with the clients. In order for the AP to bridge/repeat data from a neighboring access point, it has to be on the same channel as the neighboring access point and for association purposes, all other radio parameters should remain the same.
http://en.wikipedia.org/wiki/Wireless_distribution_system
If you have a wired infrastructure connecting these access points, then you can use Single Point Setup to connect these access points in a clusture and manage the channel assignment.

APP-V 5 SP1 - "Application Failed to Launch. This may be due to a network failure 0x0FD01B25-0000007B"

Hello all,I am having some issues with APP-V 5.
I am having particular issues with starting a packaged SIMS.net. I keep recieving:
"Application Failed to Launch. This may be due to a network failure 0x0FD01B25-0000007B"
...within a second or two of clicking on the app-v created shortcut for this software.
To clarify, I had this software working perfectly previously. I recreated this package due to a software update, but it fails to launch now. I started a new package from scratch as this is a complex piece of software with multiple installers to run etc.
To be honest, I keep seeing this error on other applications. At one point, nearly every published app returned the same error. I spent a day trying to diagnose but the following day, everything mysteriously started working again.
I have had a look on kirks blog & Tim Magan, but to no avail.
Any help would be greatly appreciated, as this is a 'business critical application' (as they say).
Quick overview of my setup:
- Single Server configuration (Management, Publishing & SQL) on Server 2012 VM in 2012 Hyper-V
- Win 2000 Domain with 2003 DC
- Windows 7 Enterprise SP1
- SIMS.net Summer 2013 sequenced on 32bit following best practice guide
- Deploying to 32 bit machine
- Client settings pushed by GPO. Powershell execution policy set to allsigned.

RESOLVED: This error is caused by the "Program Files" missing from the "C:\ProgramData\Microsoft\Windows\Start Menu\" folder.
Firstly, a big thank you Nicke. You may not have solved the problem, but you sent me down the road to resolve this issue.
After trying the step you mentioned, I placed the computer in an OU with inheritance disabled. From this point onwards, I deduced that it was actually a group policy issue.
In my environment, I redirect start menus to generated start menu. This is created using a powershell script to combine locally installed items and network items. This scripts deletes the content of the 'programdata' start menu (i.e all users start menu)
to prevent these items disrupting the start menu.
Now... The app-v packages were breaking because, the 'Start Menu > Programs' folder did not exist. If an empty 'Start Menu > Programs' exists, the packages work correctly.
I can only assume that the two packages that were working correctly - that I installed these for 'current user only', rather than 'all users'.
It seems a little silly to me that app-v should fall over for something so simple. However, you could argue that it serves me right for playing about with system files :)
Thanks again for the help.

EBS 11i - Concurrent Manager goes down due to network failure.

Hi,
We have a Single Node Oracle EBS 11i (11.5.10) [upgraded from 11.0.3] Production Instance on a Windows 2003 (32-Bit) server.
We have UPS support for the Server but the Netwok Switch is not on UPS. Due to this whenever there is a power trip the network goes down and due to this the Concurrent Manager (only)goes down. All other Apps Tier and DB Tier services are up inlcluding the 806 Listener (APPS_SID).
Is this how it is designed to work? Is there anyway to ensure that the Conc. Manager does not go down due to network failure.
