Cheers guy's was pretty sure it would be fine

Plugging in to configure will be fine...and yes I will be securing it don't worry
In fact....just looking into the wireless router it is either one of these:

So maybe it WONT work....fuck knows how it would be able to establish that and what the point of it is
