Pros & Cons
Pros
- ✓ All 5 ports are 2.5G, not one uplink plus four 1G ports
- ✓ 25 Gbps total switching capacity handles NAS and AP traffic at once
- ✓ Hits 2.5 Gbps over existing wiring, no Cat6 pull required
- ✓ Fanless metal chassis runs silent for desk or media-cabinet use
Cons
- ✗ Unmanaged: no VLANs, port mirroring, link aggregation, or web UI
- ✗ No PoE, so access points and cameras still need separate power
- ✗ 5 ports fill up fast once NAS, AP, PC, and router are connected
- ✗ No 10G port, so it caps multi-gig NAS transfers at 2.5 Gbps

SpecPicks Verdict
SpecPicks scored TP-Link TL-SG105S-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 five ports really 2.5G, or just one?
All five ports run at 2.5 Gbps. TP-Link rates the switch for up to 25 Gbps of total switching capacity, which is 2.5 Gbps in and out on every port simultaneously.
Do I need to rewire my house with Cat6 to get 2.5 Gbps?
No. TP-Link states the TL-SG105S-M2 reaches 2.5 Gbps without upgrading to Cat6 wiring, which is the main reason to pick 2.5G over 10G for an existing home run.
Will it work with my older 1-gigabit devices?
Yes. Auto-negotiation senses each link and adjusts across three speeds, 100Mb, 1G, and 2.5G, per port. Mixing a 2.5G NAS with 1G laptops on the same switch is expected behavior.
Does it have a fan, and is it loud?
It is fanless, so there is no fan noise at all. TP-Link designed it for silent operation in living rooms and offices, and the metal case doubles as the heatsink.
Can I configure VLANs or manage this switch?
No. This is an unmanaged switch with no web interface or configuration options. It is plug-and-play only. If you need VLANs or link aggregation, look at TP-Link's managed 2.5G models instead.
