Hello
Is there any way I can flood a particular wifi channel so it's basically buggered?

You'd have to get a jammer for the freq you can do ssid flooding with auth

Use a jammer, can't think of a way of specifically flooding a single channel though.
However the legal side of this is all a little dodge 
Edit - Authentication flooding on the WAP is another option
Edit 2 - Actually, you'd just target the specific frequency for that channel (ie - if it's 2.4GHz 'b', then each channels is 22MHz wide, so channel 6 would be 2.437GHz; 'g/n' is 20MHz wide etc).
So yeah it's doable but you'd need to relatively close to the target and i suspect it might causes issues with surrounding WAPs.
Edit 3 - http://en.wikipedia.org/wiki/List_of_WLAN_channels

I doubt it's possible with just a couple network cards you might have lying around. I bet it'd be easier and cheaper to just block/jam/congest the 2.4GHz frequency.
Why do you want to do this?

It's a shame I can't actually get on the network because then it's easy to bring it down.
I considered a jammer but only wanted to target a specific one and not bugger others, plus the price of them is a bit high for the purpose I need it for, I'm not that hardcore I was more in the market for something I can put together with the things I've got.
Just doing it for educational purposes.

Yeah, pretty much.
If I changed my SSID to the same name as that one would that potentially cause the machines to try and connect to my network instead? But I assume then they'd just move onto the next one once they failed on mine anyway?
I'm just open to any kind of trouble causing suggestions really, for educational purposes.

oh, rename your AP to their name, use the same channel but don't offer up any encryption/authentication. Then run a man in the middle proxy faking the ssl certs and steal all of their paypal/ebay/shit

that's a cool idea. Though it's all technically illegal anyway, im not interested in financial data, but i like the idea of using a proxy to play with their minds haha "their" being imaginery test subjects on my test network im using for educational purposes.

all educational mate.
Only dawned on me the other day you could turn your phone into a wifi screwer by setting the details the same as the gateway

What are you actually trying to do?
One of our product features is that it can block a specific SSID on a given channel.
It's done by sending a deauthentication packet to the broadcasting radio's MAC address every 250ms.
Renders it completely useless.
It might be a bit on the expensive side for a home project though!

Because I work for a WiFi vendor that sells this feature.
