Forcing A WiFi Device to Join to An Access Point

This is just an idea, and hope it can be done. I would like to test out WCL or WISM current configuration settings on a remote site. I know I can have a lightweight AP configured and joined to the remote site's wireless controller. Now my question is how would I force my wireless device to join to the AP in front of me?! If this is doable then it will help me to troubleshoot 13 remote sites right from my office. Is there a place where I can add my WiFi device's MAC address to a specific AP? Thank you for the help.

the client makes the decision on which AP to join based on RSSI + SNR + what ever magic the vendor put in place

The decision to join which AP is the sole responsibility of the wireless NIC card of the client.

You can help "influence" this by improving some of the settings on the WLC.  One of them is disable low-speed data rates from 11 Mbps and below.  Make 12 Mbps as "Mandatory" and the rest are "Supported"

You can also upgrade your wireless NIC card.  Intel has a bad run of 802.11n cards lately.  Until recently, all their drivers were useless.  I believed they released a "jumbo" pack a few months ago which helps wireless cards operate in 802.1n environment.

I have iPad users who are complaining their connection at the remote sites. District staff take their iPad and not be able to join the SSID we have created or very slow to get connected. At those sites, we have 5508 or 4402 WCL in place. The access points are 1231G in lightweight mode. For me to run a test for their connection quality, I might have to visit each site, and that's why I came up with this question. Since the device makes the decision on which AP to join, then I can isolate myself with no other APs in the area, and run the test. I could be making a testing lab with a 1231G AP joined with remote site's WCL in an isolated room and be able test out all possible wireless devices that school district carries. Does that sound right? Thank you for your inputs.

District staff take their iPad and not be able to join the SSID we have created or very slow to get connected.

Firstly, you've got 1231 so which probably means you only have 802.11b enabled.  If there's only one radio, sniff the air for any co-channel interferrence.  Do you have dynamic DCA and TPC enabled?

Next, can you try to create a PSK or even OPEN and see if there are any login improvements?  Have you checked MS AD and see through the logs the event of what happened when users attempt slow login?

Re: Forcing A WiFi Device to Join to An Access Point

Hi,

Just adding....to all other answers....

There is not a way to force the wifi device to use a specific AP from the  controller side of things.  As per the specs the client decides when and  where to associate.  You could try disabling some of the lower data  rates or lowering the AP's tx power to reduce the coverage cell of each  AP.  By doing this the client might not see the other AP as favorable.

Not too sure if I want to do that in our environment. Do not want to interrupt other users wireless connectivity during my test with a specific access point.

What would you do if you have 10 different mobile devices and want to test them out to see how well they will react to a remote WCL? Take those 10 devices from site to site? We have 23 remote sites with WCL and WISM. Or test them in an office with an AP joined to a remote WCL? But I do not want to alter other APs in the area to make office people angry.

We have 23 remote sites

I have >98 schools to manage my wire and wireless.  I've never seen a behaviour like yours.  Then again, I don't have AP1230 in my network anymore.

Not really sure when the 1231G will be phase out totally. Some schools have controller either WCL or WISM with 1231G joined. We have been converting lots of 1231G to light weight, so we can easily change from WEP to WPA2, and also start implementing BYOD to schools that are equiped with light weight access points. BYOD is new to us, and just started this year. My team lead just announced another wireless upgrade to our core sites, and finally we will be getting ICE and Cisco Prime. With that I hope the new installation will improve users using all types of mobile devices. In the mean time we are just patching holes on a flat tire.

Ok, you're not going to get any benefits with BYOD if the 1230 will be there.

1230 are only 802.11b/g.  You can stick 802.11a radio module but at the end of the day, the 1230's FastEthernet port will be one of the bottlenecks.

In regards to WPA2, the 1230 needs to have a radio upgrade AIR-MP21G-X-K9.

Too many hassles to get an old product to support BYOD.  Plus it's already end-of-support.  If your AP dies, you have to pay a fortune in Service Contract.

You're better off getting the APs upgraded.  Talk to your Cisco SE/AM and ask them about Cisco Technology Migration Platform.  This program means that you can get a discount for every old equipment (including non-Cisco) traded-in, like-for-like.   Say you traded-in 20 APs, then you get a $$ off 20 new Cisco APs.  You can't trade in 20 APs and hope to get $$ off 21 APs.
