Watch out

  • The M2 suffix means 2.5G ports; the plain TL-SG105S is a gigabit model.
  • Versions V1 and V2 share the same spec table.

Why people pick it

  • All five ports do 2.5 Gbps for multi-gig internet and Wi-Fi 6E/7 access points
  • Runs on existing Cat5e cabling (maker note), so no rewiring
  • Fanless metal case is silent and small enough to tuck away

Know before you buy

  • Unmanaged: no VLANs or management of any kind
  • No 10 Gbps port for a fast uplink
  • External power adapter needed
