Pros & Cons
Pros
- ✓ All 8 ports run 2.5G, not just one or two uplinks
- ✓ 40 Gbps total switching capacity for concurrent multi-gig transfers
- ✓ Auto-negotiates 100Mb/1G/2.5G, so older gear still connects
- ✓ Rated for 2.5 Gbps over existing Cat5e - no rewiring to Cat6
- ✓ Fanless chassis, silent in a media cabinet or on a desk
Cons
- ✗ Unmanaged: no VLANs, no web UI, no port mirroring or QoS
- ✗ No SFP+ or 10G uplink port for a faster backbone
- ✗ No PoE, so cameras and APs still need separate power
- ✗ Needs 2.5G NICs on both ends to see any gain over gigabit

SpecPicks Verdict
SpecPicks scored TP-Link TL-SG108S-M2 using a rating × review-volume × price-fit model applied to published specs and reviews across the networking category. TP-Link's networking lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for networking of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
Frequently Asked Questions
Are all 8 ports 2.5G, or only some of them?
All eight ports are 2.5-Gigabit. TP-Link rates the switch at up to 40 Gbps of total switching capacity.
Do I need Cat6 cable to get 2.5 Gbps?
No. TP-Link states you can reach 2.5 Gbps without upgrading to Cat6 wiring, which is the main reason to pick 2.5G over 10G for an existing house.
Will my older gigabit devices still work on it?
Yes. Auto-negotiation senses each link and adjusts across three speeds - 100Mb, 1G, and 2.5G - so mixed-speed gear shares the switch without setup.
Is this switch managed? Can I set up VLANs?
No. The TL-SG108S-M2 is unmanaged, so there is no web interface, VLAN configuration, or QoS. It is plug-and-play only.
Does it have a fan, and how loud is it?
It is fanless. TP-Link describes it as silent operation, which is why it suits home offices, media cabinets, and desks.
