Rogue WiFi SID with obscene name. How to get rid of it?

I have an unusual question about a problem a client who is a church has.   They discovered last Sunday in the morning service someone had taken their cellphone presumably and created a WiFi hot spot with the SID named "F*** OFF!"  Since the church has a Public WiFi network available to the worshipers so they can access an online bible, some of the users when trying to connect to the normal WiFi network discovered this rogue SID.  Can you think of any way I could help the client get rid of the rogue SID?  It is embarrassing to the client and they are hoping I can do something to help them out.  Many thanks if you could give me some ideas.

there's absolutely no way of getting rid of a broadcasted SSIDs
You can DoS a rogue AP - but that will just disconnect clients - and not showing SSID.

The easiest (??) would be to contact the owner of the SSID - they've maybe just used that SSID to show other people not to connect - and not to be offensive

You don't think that the SID name is not offensive?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

wether the name is offensive or not is not put of for discusssion, I just said that the name maybe wasn't set to offend ..

Put to sum it up - the only way to get rid of the SSID is to get the owner to turn off the AP or get the owner to change SSID

It is possible to find your rogue access point but you'll need a tool such as Flukes' AirCheck  or if you have a laptop you can download NetStumbler.  

You'll look a little silly doing it during church but you walk around and find a general direction by watching the single strength coming from the rogue access point as displayed by NetStumbler.  You can usually easily narrow down to a single room and in large rooms to an area of the room using this technique.  

Then you just have to walk off that section of the room and you'll know by single strength readouts once your on top of the device.

it's not easy to specify location of a rogue AP using only netstumbler og inSSIDer or similar tools. If you're in an area with few houses - this is maybe possible, bt if you have several houses nearby, maybe also a housing complex - then you need at least 3 wireless radios to triangulate, and then MAYBE you can locate AP.

I guess this rogue AP isn't located within the church? if so - look at switches and MAC-addresses

I agree it isnt easy using the laptop but it can be done. If this is truly a wifi hotspot via phone from someone at church they will notice you looking and it might be enough to discourage.

I have had quite a bit of luck using a fluke air check with a wand however if you can get your hands on one - they are about 1500 otherwise.
