Right im a noob on the this networking stuff guys 
My dad's recently upgraded are orange boardband package to the max with free VoIP calls which sound great but isn't.
First orange sent there "Orange Livebox" which you have to use for the free VoIP calls but the problem is we have a Netgear DG834Gv2 already set up and working nice
Now i've got the livebox working but the wireless signal isn't very good and there's only two etherent ports on the livebox.
I spend all day yesterday playing around with both and atm i have the livebox as a gateway/modem i believe and the netgear as the main router which the livebox is feeding the internet to the netgear and the both are connected by a ethernet cable.
Which at first seem to work great but when using the wireless from down stairs its very slow
So im thinking could it be the ethernet cable which is connecting the twogether be slowing the speed down.
What the best type of cable to use ?
Cat 5 , Cat5e, Cat6
UTP or STP or cross over ?
