[Sissinghurst]

Hello,

I would like to stop this Kindle automatically connecting to wifi if a button is accidentally pressed (eg on suggested Wikipedia lookup whilst reading). It seems to be very easy for that to happen with this model - you don't have to go into the menu and make several choices before it connects (as with older models, which I'd prefer.)

A while ago, as there seems to be no "forget" button for networks on it, I tried to change the password to one that didn't work with the network, and save it, but it looks like that didn't work as it accidentally connected again.

Aside from changing the router password itself, is there any small hack that can be done for this?
Would prefer not to jailbreak it fully (never done that before) and leave it in a state where it could potentially be resold if I ever needed to do that. Is
