Aironet 350 w/ Linksys WAP11

I'm trying to add an Aironet 350 PC card to an existing Linksys WLAN. I've configured the WLAN for WEP-disabled, open access. I've set all the parameters on the 350 to match a working Linksys card. I've disabled MAC control on the Linksys Access Point.
The Aironet Client Utility reports that the card is "not associated". When I bring up statistics, I see lots of PLCP CRC errors.
Any pointers?

No 2.4Ghz equipment in the house (except possibly the microwave, which is not running). The linksys is using both antennas. I'm not dead certian what 'diversity' means, but it sends/receives on each. Also, when I'm communicating with a LinkSys PC Card, I'm getting 100% signal strength and 100% signal quality, so the problem would not seem to be electronic noise.
The retailer's support staff has suggested that I ensure that the WAP is using the same protocol! (Um... I think that's what WiFi/802.11b means.)
I've tried setting up the Aironet card and the LinkSys card on a different laptop. Same results. When the Linksys card is in, it talks to the WAP, but the Aironet says it is not associated, and shows lots of CRC errors.
Any other ideas, or should I just throw in the towell and send it back?
Thanks in advance!

Aironet 350 Wireless Bridge Problem

I have inherited a wireless link between two building that used a pair of Aironet 350 wireless bridges. I say used because one took a lightning strike and is fried. I need to see the configuration on the remaining bridge to set up the new bridge but no one knows the user name or password to access the remaining functioning 350. How do I reset this old buzzard? I have tried all the instructions I have found on this site and others. There is no reset button. I found this out by disassembling another Aironet 350 we had which has also taken a strike. I cannot set up the new 1300 without knowing the config of what it will be talking to. I have been able to connect to the 350 with a serial cable and I can see some of the information. But the only thing I get is the ip address for fe0. I have attached the file I captured to this post. Any help will be appreciated. Thanks.

If you know the IP of the 350, put a laptop on the same subnet and use a crossover cable to web to its GUI. VxWorks CLI sucks!
If you can get hold of a pair of 1231 APs, they can be configured to run in bridge mode and use the same antennas as the 350s. Benefits are IOS and G radios.

Securing Aironet 350 Access Point

Hello -
My small network is operating correctly using the Aironet 350 Access Point and multiple clients. However, the setup is not secure.
How is it possible to secure access to our AP?
Specifically: I would like to establish a WEP key, as some devices (i.e. pocket-pc's) do not support more advanced security schemes.
Thanks,

Extensible Authentication Protocol (EAP) authentication, also called 802.1x authentication, provides dynamic WEP keys to wireless users. Dynamic WEP keys are more secure than static, or unchanging, WEP keys.
For more details on configuring both types of WEP refer the following document,

Aironet 350 with pismo antenna?

Hi people. I recently bought a cisco aironet 350 pccard wireless adapter for my pbg3 500. It works, i use os x 10.3.5. The problem is it doesnt reach very far. Last week a friend of mine came with his macbook and he had full signal at places where I could not even connect.
Doing some research I found that removing the fat sticker placed on the part of the card that remains outside the powerbook, there are 2 antennas and a jack for an external one. So I tought I could use the one built-in the display that is meant for airport cards. The problem is they can not be conected directly (the cable doesnt reach and the conectors are different anyway. To make thinks worse, the powerbook cable doesnt even have the conector, just the wire. I tried making a bridge between this cable and the cisco jack (using a 15 cm cable) but doesnt improve the signal, so I think im doing something wrong, or the pismo antenna is no better than whats built into the cisco card. Maybe someone here has some experience on using a non airport card with the airport antenna.
Thanks in advance for your help.
Pepo

Thanks Brent. I have a spare ibook display that I can use for testing the antena. Problem is I dont want to burn the pccard amplifier. I dont know how the antena works, or if there is already an amplifier in the display, so if I connect the output of the card to the airport antena, I may burn the card. If I touch the antena lead it has power, as well as the pc card, so I dont think they can be connected toghether.
Also another doubt I have is actually how the antenna works. If I check the jack with a tester, I can see that the shield and the conductor of the wire arent isolated from each other, so then how do you wire them to the card when they are bridged already?
Sorry, hope I explain myself a bit at least, my english is not good enough I think for this kind of things.
Thanks again.

Aironet 350~~ Help Factory Settings must be RESTORED

Hello,
I am the proud and happy new owner of the Cico Aironet 350 wireless access point. Now the issue (acquired by the company's buyout of another one), needless to say when I get it there is no username/passwords included. Just the cable/power supply and the wireless access point it self. Has anyone here ever worked with this unit before and if you have, do you know how to reset to the factory defaults?

Hi Joshua,
Here is the method to do a factory reset;
Reset the AP 350 That Runs Cisco IOS Software
Complete the steps in this section in order to reset an AP 350 that runs Cisco IOS Software.
Note: Cisco IOS Software-based APs have a default configuration that includes a username and password combination. Both the username and password are "Cisco", which is case-sensitive. After you reset to factory defaults, be prepared to give "Cisco" as both the username and password when you are prompted by either the GUI or the CLI.
The AP350 does not have a MODE button to reset the AP to factory defaults. So, if neither the GUI or CLI is available with sufficient privileges in the AP350, complete these steps to delete the current configuration and return all access point settings to the factory defaults using the CLI.
Reboot the access point by removing power and reapplying power. Let the access point boot until the command prompt appears and the access point begins to inflate the image. When you see these lines on the CLI, press ESC: Loading "flash:/" ...########################################################################### ################################################################################ ################################################################################ ####################
Once you press ESC, this information is displayed on the CLI screen..

Aironet 350 WAP + IP Scheme Change

Hello,
I have an Aironet 350 Wireless Access Point running VxWorks 11.07. We had it working fine on our 172.23.0.X IP address schema where the Ethernet and AP Radio shared the same IP address.
We have recently moved to a 10.121.40.X IP address schema and so I made very simple changes to the network configuration of the WAP (IP address, Subnet Mask, Default Gateway and DNS). However, now I can't get any devices to connect to the WAP even though I know they did before with the old IP address schema. I've even tried the WAP on DHCP and the result is the same.
What can I do to get this WAP working again? Is it something to do with the 10.121.40.X range?
Thanks.

The clients are trying to connect but in Windows don't get to the 'Acquiring network address' stage.
After a failed connection attempt the VxWorks 'Associations' page lists the client device but the 'State' is 'UnAuth'.
The WAP Event Log shows a lot of the following type of entries but nothing else:
00:07:57 (Info): Deauthentication from [10.121.41.19]0012f0dc17ca, reason "Unspecified Error"

Aironet 350 Bridge associations

Hi,
I have 2 aironet 350 bridges that keep disassociating and then reassociating constantly. Is there any way to stop this form happening?

Parent is "Root Bridge", end station is "Non-root bridge w/out clients." Thanks for pointing me to the Express setup page--that's the one I had in mind, but I haven't been there since day one. Now I need to figure out why, with those settings, it's allowing client connections...
The only MAC address filtering I see is (per documentation) "allow or disallow the forwarding of unicast or multicast packets either sent from or addressed to specific MAC addresses." When I look at the actual Address Filters page, it only allows me to specify "Dest Address." Not much help if I don't want to allow other connections *to* the bridge...
When I'm not in Express Setup, and go to the Setup page, I have the option at the bottom of the page (Network Ports | Bridge Radio or Network Ports | Root Radio) to go to an Advanced page. While there, I see a field called "Radio Cell role." The Root Radio Advanced page shows the Radio Cell role as "Access Point / Root." The other options would be "Client/Non-root" and "Repeater/non-root." The Bridge Radio Advanced page shows the role as "client/non-root." I am *assuming* that the Root radio here, although called an "access point" is not an access point for clients (i.e., its role is that of the access point for the far end(s) of the bridge).
I can't find anyplace to stop broadcasting the SSID...
Thanks for the help!

Aironet 350 Failure...Twice

A couple of months ago, I installed three Aironet 350 Bridges, each connected to directional antenna via LMR400 cable. The directionals are pointed towards an access point at the front of the campus. After abou 36-48 hours of use, the ethernet ports on the bridges locks up, and actually dies in two of the instances. I figured that it was a bad group of bridges, so we replaced them with three more, only to have two of the replacements do the exact same thing. When the port crashes, the red light comes on and stays on, even after you remove the rj45 connector. Afterwards, you are unable to access the bridge via a browser, so there is little means of troubleshooting available. I haven't had a lot of luck with the reseller, and this customer has been down since March!!
Any help would be greatly appreciated

Aside from on-site consulting (possibly on a contingency basis), I can only suggest that you pull it all into a lab, check all the configs, upgrade all the firmware and confirm that it's reliable before putting it back in.

Aironet 350 PCMCIA WiFi CARD

I'm having a problem with a Cisco Aironet 350 WiFi PCMCIA Card (speed has to be auto) installed in a Sony Camera and intermittently not connecting to a ZyXEL ZyAIR G-110 WiFi PCMCIA Card (speed set to b only (which is 11 MBPS))which is installed in a Dell Laptop. On startup (laptop first then camera) it sometimes connects and sometimes doesn't. The ZyAir card is always fully initialized first then the Aironet is initialized.
What I also noticed that was strange is that if you toggle (fn + F2) the Centrino WiFi NIC (built into the laptop) on and then off the Aironet suddenly establishes connectivity.
Any help would be appreciated.

If you use a non cisco card you can NOT use any Cisco enhancements to the standards including LEAP or 128 WEP. 40 Bit WEP will work fine as long as your card supports it.

Aironet 350 reset to factory config over vacation.

I have an Aironet 350 non-root bridge that was reset back to its factory default configuration over a 5 day period of inactivity (Christmas vacation). I didn't set it up, so I can't say too much about how it was configured before except that it was running 12.0 firmware.
I have upgraded it to 12.04 and reconfigured it and it seems to be running fine.
Any ideas on what could have caused this? Could I have had a security breach?

That could be very likely. Are you using a default configuration for security, or have you turned user-manager on and added a management username/password. Note that someone could have potentially done this via SNMP also.

AIRONET 350 - Duplicating configuration to a replacement

I have a problem with one of our AP it's a aironet 350, what is the easiest way to copy it's configuration to a replacement device of the same type.
I have just took over from out wireless guy who is off long term sick and I'm in at the deepend.
Regards
Mike

Hi Mike,
I have actually never tried this myself, but here is a good doc that discusses this process. Maybe somebody else will weigh in as well :)
Working with Configuration Files
This section describes how to create, load, and maintain configuration files. Configuration files contain commands entered to customize the function of the Cisco IOS software. To better benefit from these instructions, your access point contains a minimal default running configuration for interacting with the system software.
You can copy (download) configuration files from a TFTP, FTP, or RCP server to the running configuration of the access point for various reasons:
To restore a backed-up configuration file.
To use the configuration file for another access point. For example, you might add another access point to your network and want it to have a configuration similar to the original access point. By copying the file to the new access point, you can change the relevant parts rather than recreating the whole file.
To load the same configuration commands on all the access points in your network so that all the access points have similar configurations.
You can copy (upload) configuration files from the access point to a file server by using TFTP, FTP, or RCP. You might perform this task to back up a current configuration file to a server before changing its contents so that you can later restore the original configuration file from the server.
From this AP350 doc;
http://www.cisco.com/en/US/products/hw/wireless/ps458/products_configuration_guide_chapter09186a00801d016d.html#51335
