Pc help needed please

The switch is a accton 3024c

My sky router is a bit knackered, but the sky monkeys said there is a fault on the line.
The router stopped working properly on thurs, I can't connect with LAN but could via wireless and couldn't connect with my iPad. Reset it a million times and it started to work with the wireless again

The switch I had connected straight to the laptop. Via a short (1m) normal not crossover cable.
And it wouldn't aquire an address.

On the router dhcp is on.(as standard)

I can't check the laptop settings as I'm out at the second but I will when I get home

Thanks for your help
