Best small 2.5 GbE switches

Five-port and eight-port 2.5 GbE switches for mini PCs, NAS boxes and Wi-Fi 7 access points.

Editorial opinionReviewed Oct 29, 2026

Most mini PCs, NAS boxes and fibre routers sold in 2026 have 2.5 GbE ports. A gigabit switch caps them at about 110 MB/s; these switches run them at full speed on the Cat5e cable you already have.

How we chose

  • At least four 2.5 GbE RJ45 ports.
  • Fanless unless the features justify a fan.
  • VLANs as a bonus, not a requirement.
  • Specs checked with the manufacturer in October 2026.
