Router Will Not Turn On

I have a D-Link Router, model DIR-615. We used to have two phone lines and the one phone connected through the internet. We forgot we stopped having the one phone line and spent an hour or so trying to make the internet come on and the phones work.

The phones now work but I can only get internet access of I hook up my laptop directly to the speedtouch. I was attempting to fix the internet so I unplugged everything, took away the now unneeded talkbroadband box and reconnected everything.

Now the router refuses to even turn on. Not even the power light will glow. Normally everything glows, even if one light is red but now it's as if its not connected to power. I made sure to reconnect everything properly and I know which wires went were but even changing the electrical outlet won't work and I'm getting desperate. We need the wireless for work.

Help would be much appreciated.
