Updated: October 9, 2026

Got a 2.5GbE port on your NAS, PC or Wi-Fi 7 router, but only gigabit everywhere else? A 2.5GbE switch is the cheapest way to add more fast wired ports. Here’s what to look for, and five options from TP-Link, NETGEAR and Ubiquiti.

How we chose: research-based. We compared manufacturer specifications (cited below, checked October 9, 2026). We have not physically tested these products.

Quick picks

• Small and simple (5 ports): TP-Link TL-SG105S-M2 or NETGEAR MS305 [1][3].
• More ports (8): TP-Link TL-SG108S-M2 or NETGEAR MS308 [2][4].
• Managed, with a 10G uplink: UniFi Flex 2.5G [5][6].

What to look for

• Port count. Count your 2.5GbE devices (NAS, PC, access point, router) and add one or two spare.
• Unmanaged vs managed. Unmanaged switches are plug-and-play: NETGEAR says the MS305/MS308 need no software or configuration [3][4]. A managed switch like the UniFi Flex 2.5G adds features such as VLANs and port mirroring, managed through the UniFi Network app [5].
• Cabling. TP-Link says its 2.5G switches work with Cat5e, Cat6 and Cat6a cables, and that Cat5e or better doesn’t need replacing [1][2].
• Noise. All four unmanaged picks are listed as fanless [1][2][3][4].
• Warranty. NETGEAR’s sources conflict for the MS305 and MS308: the product pages say “limited lifetime hardware warranty” [3][4], but NETGEAR’s datasheets and its warranty table list 3 years [8][9][10]. Confirm the term with NETGEAR or the seller before you buy. TP-Link’s product pages don’t list a warranty term [1][2]. Ubiquiti gives 2 years when bought from its own store, and 1 year from Ubiquiti’s shipment to the reseller when bought elsewhere [7].

TP-Link TL-SG105S-M2: compact 5-port

Who it’s for: a desk or media cabinet with a few 2.5GbE devices.

• 5 × 2.5GbE ports (100 Mbps/1 Gbps/2.5 Gbps auto-negotiation), 25 Gbps switching capacity [1].
• Fanless, metal case, desktop or wall mounting [1].
• 802.1p/DSCP QoS and IGMP snooping [1].
• Lowest listed max power here: 5.81 W [1].
• Watch out: TP-Link’s page doesn’t list a warranty term [1].

NETGEAR MS305: 5 ports, metal and fanless

Who it’s for: the same small setups, in a metal, fanless case.

• 5 × 2.5GbE ports (100M/1G/2.5G) in a metal case [3].
• Fanless; desk, wall or under-table mounting with the included kit [3].
• Energy Efficient Ethernet (IEEE 802.3az) and 802.1p QoS [3].
• Warranty conflict: the product page says limited lifetime, but the datasheet and NETGEAR’s warranty table say 3 years [3][8][10]. Confirm before buying.

TP-Link TL-SG108S-M2: 8 ports, plug and play

Who it’s for: a home office or network cabinet with more wired devices.

UniFi Flex 2.5G: managed, with a 10G uplink

Who it’s for: UniFi households, or anyone who wants VLANs and a faster link to a 10G NAS or router.

• 8 × 2.5GbE ports, plus one 10G combination uplink you can use as 10 GbE RJ45 or 10G SFP+ [5][6].

• Powered by USB-C (5 V, 3 A) or PoE+ [5].
• Desktop, wall, DIN or magnetic mounting (DIN and magnetic mounts sold separately) [5].
• Watch out: it’s managed in the UniFi Network application (version 9.0.114 or later) [5], so it suits people already using, or willing to set up, UniFi. Polycarbonate case, not metal [5].

FAQ

Do I need new cables for 2.5GbE?
TP-Link says Cat5e or better doesn’t need replacing for its 2.5G switches [1][2].

Will a 2.5GbE switch make my internet faster?
Only if your internet plan and router are faster than gigabit. Within your home, it speeds up transfers between 2.5GbE devices, like a PC and a NAS. (Planned guides: Best Wi-Fi 7 mesh systems for 1–2.5 Gig internet; Synology vs UGREEN vs UniFi NAS for beginners; Best budget NAS for Plex and Jellyfin.)

Do these work with 1GbE devices?
Yes. Every switch here lists 1G (and 100M) support on its 2.5GbE ports [1][2][3][4][5].
