I just got my mac yesterday and found I was only getting about 25 mbs/5mbs of the 50/5 i should have been getting. After spending the entire morning at the house with a TWC tech trying to work on the speed i was getting we tested my old pc laptop and it is getting 52mbs/5mbs..... Is there something holding back my MAC that i need to change or a setting or something? First time Mac Owner here. Also, I was going to purchase the Time Machine, but TWC gave me a modem/router all in one. So is it necessary to have time machine? and or can it be hooked up without interference?
