I've just got a smart tv and want to connect it to a router. The manual says I need a Cat 5 SPT LAN cable. I've been looking online but the closest I can find is Cat 5e STP Network cable, or Cat 5e STP RJ45 male to male patch cable. I know this makes me seem pretty dim but the more I try and find out about this stuff, the more confused I get. Are these all the same type of cable and if not, which one best matches what I need?
