QNAP QSW-1108-8T-R2 vs TP-Link TL-SG108S-M2

For a small wired home network, our default 2.5G switch is the TP-Link TL-SG108S-M2 V2: its smaller case and documented wall mounting make placement straightforward. Choose the QNAP QSW-1108-8T-R2 for front-facing LEDs, rear cabling and loop blocking without a separate enable step. Both provide eight 2.5GbE ports; the decision is about installation and support, with no speed winner established by these specifications.

Each switch has eight ports supporting 2.5 Gbps, 1 Gbps or 100 Mbps. Using one for the router leaves seven endpoint connections, calculated from that port count. Sources: QNAP R2, TP-Link V2.

Compare the exact R2 and V2 models

The table uses the QNAP US product page, its hardware and package listing on QNAP's Chinese site, the TP-Link V2 datasheet and installation guide. Dimensions are reordered into the same width/depth/height sequence. Maximum-consumption figures are each maker's published limits, not measurements under matched loads or a prediction of your electricity use.

Keep the full model names. QNAP's recommendation here is specifically the R2. TP-Link's is TL-SG108S-M2 V2, including the S: the separately documented TL-SG108-M2 V2 has a larger 226 × 131 × 35 mm case. TP-Link's support selector also lists other revisions; do not transfer this V2 feature list to unspecified stock.

Default pick: TP-Link TL-SG108S-M2 V2

Pick the TP-Link when you want the smaller enclosure or intend to mount the switch on a wall. Its V2 specifications list fanless cooling, a metal case, loop prevention, 802.1p/DSCP QoS and IGMP snooping. Those automatic traffic features are useful distinctions to check, but they do not make it a configurable managed switch.

The installation guide specifies 110 mm between mounting holes for TL-SG108S-M2. Use that model's row: the shared manual illustrates TL-SG105S-M2 and covers several switches. Plan suitable wall fixings; screws are absent from the V2 datasheet's package list.

For routine switching, TP-Link describes plug-and-play deployment. For fault-finding, the manual distinguishes the 2.5G LED from the 1G/100M LED, so check the indicated link rate before blaming a slow backup on the switch.

Best for a tidy desktop: QNAP QSW-1108-8T-R2

Choose the QNAP when a visible status display and rear cable routing suit your desk. QNAP explicitly describes front LEDs and rear ports, plus automatic loop detection and blocking with no configuration needed. Those are firmer reasons to choose it than assuming a QNAP NAS requires a QNAP switch: both switches document ordinary multi-speed RJ45 Ethernet connections.

QNAP describes internal heat sinks, metal heat-dissipation plates and ventilation holes in its fanless design. Leave ventilation unobstructed. Fanless cooling is documented for both models, so it does not establish that either runs cooler in your room.

The R2 hardware/package listing documents the power supply and mounting accessories, but calls the form factor desktop. Use the supplied installation guide to confirm your intended mounting arrangement. Do not infer an installation restriction merely from the word desktop, or borrow dimensions and power details from another QSW model.

Allocate every port before ordering

Neither specification lists a separate uplink: the router connection uses an ordinary port from the same eight-port pool. Here is a worked allocation; the counts are our arithmetic, not an extra manufacturer capacity claim.

That layout has six downstream connections in use and one spare after the router uplink. If you need eight endpoints plus the router, neither model is large enough. Retaining the gigabit switch is an option for devices that do not need multi-gig links; its connection still consumes a port here.

Keep the NAS and fast computer on this new switch. With a gigabit router uplink, traffic crossing that uplink remains limited to gigabit, but local traffic between those multi-gig devices does not need to cross it. That is why a local NAS upgrade can make sense even before upgrading your internet plan. These are consequences of the documented port rates and connection layout, not measured transfer results.

The 40 Gbps switching-capacity figure is aggregate; it does not give a NAS a 40 Gbps connection. Both individual port specifications top out at 2.5 Gbps. For other layouts and configurable features, see our managed vs unmanaged switch guide.

Check NICs, cables and power before replacing gigabit

Start with the devices doing the transfer. QNAP documents negotiation at 2.5G, 1G or 100M according to the attached device; an existing gigabit NIC still negotiates a gigabit link. If every relevant endpoint remains gigabit, keep the existing switch until a faster endpoint creates a reason to upgrade.

For cabling, TP-Link's V2 datasheet specifies Cat5e or better, up to 100 m for 2.5GBASE-T. Try compliant existing runs before ordering replacements. If a link negotiates below the expected rate, check the NIC settings and substitute a known-good patch lead: TP-Link's troubleshooting guidance recommends checking connection speed, auto-negotiation and standard cabling.

If leads are missing, Cable Matters 160001 Cat6 is an optional indoor patch-cable family with bare-copper conductors and snagless boots, according to its official specifications. The existing linked variant is one black 7 ft cable; choose another length when the route requires it.

Check price on Amazon. Our Ethernet cable guide covers category choices beyond this upgrade.

Both switches list an adapter and a 12 V / 1 A DC requirement or output. That alone does not confirm interchangeable plugs or polarity: use the supplied adapter, confirm the local mains plug and keep its label with the switch. TP-Link's manual instructs users to use recommended adapters. Treat access-point power as a separate purchase requirement; these specifications provide no PoE power budget to allocate.

Neither is the right choice if you need to configure VLAN membership for separate networks. TP-Link's VLAN explanation states that unmanaged switches do not support VLAN configuration; its automatic QoS and IGMP features do not change that limitation.

Confirm the revision and warranty route

Before paying, request the exact model/revision and supplied-adapter details in the order description. TP-Link says the hardware version is on the product label, usually as Ver: X.X or VX (label guide). Match that to the regional support selector, rather than assuming a listing title identifies V2.

QNAP's US R2 page states a two-year warranty and directs customers to its service portal. For TP-Link, the current US warranty policy lists three years for non-Omada switches with steel chassis. The model page says metal casing, so confirm the exact product's category and serial eligibility with TP-Link instead of promising a blanket lifetime warranty. Its policy requires valid proof of purchase and the complete serial number, and excludes unauthorized-reseller purchases. The documented replacement route is product registration, technical-support troubleshooting, then an authorized RMA.

1. 1

   Match the model

   Keep QNAP's R2 suffix or confirm TP-Link's V2 label and regional documentation.

2. 2

   Check the box and location

   Confirm the supplied adapter, local mains plug, cable reach and mounting fixings.

3. 3

   Connect and inspect

   Use the router's LAN side, check link-rate indicators and enable TP-Link loop prevention if wanted.

4. 4

   Keep support evidence

   Save the invoice, serial number, hardware revision and adapter details for a support request.

How we choose

This is a documentation-based comparison, with no physical or speed testing. We compared official model pages, TP-Link's V2 datasheet and shared installation guide, QNAP's R2 hardware/package listing, and US warranty documentation. The recommendations prioritize equal endpoint capacity, placement, documented setup and a usable support route. Port allocations and bottleneck explanations are our stated deductions from those specifications. Full editorial method: How we choose.

Verdict

Choose TL-SG108S-M2 V2 for the smaller case and documented wall mounting, remembering the loop-prevention switch. Choose QSW-1108-8T-R2 for its front status display, rear cabling and automatic loop blocking without that setup step. Order the chosen switch with its supplied adapter and only the patch leads your port plan is missing; keep the current gigabit switch if your endpoints cannot use faster links.
