How do you turn wireless off?

How do you turn wireless off?
My next door neighbour tells me that if I’m not using the wireless part of my modem/router, I should disable it or switch it off.   Can any tell me how to do that?  I’m using the Speedtouch 585 v7.0.
Thanks
Jessica

go here http://192.168.1.254/cgi/b/intfs/?be=0&l0=3&l1=1  click the WLAN, then configure at the top, top item, remove the click  i.e. dont enable

Unscrewing the aerial generally works as well if you're not confident about changing configurations.

it only one click enable or not, thats easier than removing the antenna

Some of the Thomson's have non-removable aerials too, I think.

Here's where you need to look.

Thanks Guys,
I just disabled it.  Pointless having it on if I don't use it.
Cheers,
Jessica
