$20 under your budget

■ The catch — co-equal billing, always
Five ports means four devices. One goes to the router, and you are left with four — while the eight-port TRENDnet TEG-S380 sits at ~$75, still under your cap. Buy this only if you know exactly what is plugging in and it will not grow.
Dealbreaker? Runner-up №1 has eight 2.5GbE ports for $15 more ↓

Traps — this verdict avoids
Wired ports, not Wi-Fi
A switch adds wired ports only — it does not extend or improve Wi-Fi coverage. If the goal is a better signal upstairs, you need an access point, mesh node, or extender. A switch will not add a single bar.
The brand premium
Near-identical 8-port 2.5GbE switches sell anywhere from ~$49 to ~$150 — you are paying for the warranty channel and idle draw (~1W vs ~5W), not for speed. Prices in this class are unusually volatile; check the live price the day you buy.
Unmanaged is unmanageable
Unmanaged switches have no VLANs, QoS, or link aggregation — perfect for a flat home network, wrong the moment you want to fence IoT cameras or a guest SSID onto their own segment. Get that wrong and you re-buy at ~$133.
