Our modem is dying an overly-dramatic death so went and got a new one last night, right before the shop closed... Of course I got the wrong one and wasted half an hour trying to make it work. This is why I spend ages opening boxes with the least amount of damage possible.
Back to the store this morning to confess I'm an idiot and can I please swap this opened box for something else?
I got one for DSL that you have to mess with to make work with fibre. If I'm spending that much money on something I'd rather get the right one and have it work out of the box.
