Ethernet LAN Cables — Cat5e to Cat8 (6)
How to Choose a Network Cable
Three things decide it: the speed of your line, the distance of the run, and where the cable will sit. Match the category to your speed (Cat6 covers most homes), pick a length with a bit of slack, and choose shielding only if the cable runs near power or in a noisy electrical environment.
Cat5e and Cat6 both handle gigabit internet for most homes, with Cat6 giving more headroom. Cat6a supports 10Gbps over longer runs and is worth it for fast fibre or a NAS. Cat8 targets 25/40Gbps over short distances for servers and data centres — overkill for a normal home line. Buy for the speed you actually have, not the highest number.
Standard twisted-pair Ethernet is rated up to about 100m for a single run before the signal weakens. For home use that's rarely a limit. Order a length with some slack so you can route the cable neatly along skirting or behind furniture rather than stretching it across the floor.
Unshielded (UTP) cable is fine for most homes and offices and is more flexible and affordable. Shielded (STP/FTP) cable adds a foil or braid that resists interference, which helps when the cable runs alongside mains power, through a server room or in an electrically noisy space. If in doubt for a normal home run, UTP is enough.
Patch cables use stranded cores that flex well for short links between a PC, router or switch. Solid-core cable holds up better for long fixed runs inside walls or trunking but is stiffer. For plugging gear together on a desk, a flexible patch cable is the right pick; for a permanent in-wall run, choose solid installation cable.
A cable only helps if it was the bottleneck — for example replacing an old Cat5 or damaged lead. It can't make your line faster than the speed your ISP and router deliver. Match the category to your line speed; beyond that, a higher category adds future headroom rather than instant speed.
