Buying guides
Which one, for the network you actually have
A hub compares everything in a family. A guide answers one question — a budget, a first NAS for someone who has never run one, what a flat with thick walls needs before a faster router — with a ranked shortlist and a reason for the order.
- First mesh system
A first mesh system for a home the signal will not cross
Thick walls decide the backhaul: wired, a dedicated band, or shared. Five mesh systems sold on Amazon.com, checked October 26, 2026.
- Router upgrade
Replacing the router your provider left, and knowing whether you should
Replace an ISP router only once you know what it does besides Wi-Fi. Five Wi-Fi routers sold on Amazon.com, checked October 26, 2026.
- Access points
Access points for a house that already has cable in the walls
With cable in the walls, ceiling access points beat mesh. Three Wi-Fi 6 access points sold on Amazon.com, with PoE and management compared.
- Extenders & powerline
Extending coverage where no cable can be run
No cable run? Powerline or mesh, and what each loses on the way. Five kits sold on Amazon.com, with breaker and outlet rules, checked October 26, 2026.
- Home switch
Choosing a switch for the ports you will actually fill
Managed or unmanaged, port count, fan and case: what decides a home switch, with four switches sold on Amazon.com, checked October 26, 2026.
- PoE switches
A PoE switch that will actually power what you plug into it
A PoE switch is chosen on its total power budget, not the per-port figure. Five switches sold on Amazon.com, checked October 26, 2026.
- First NAS
A first NAS enclosure, chosen on bays before terabytes

- SSD upgrade
Putting solid-state into a machine you already own

- Second copy
The drive that holds the copy you would actually miss

- Faster adapters
Getting one machine onto a faster link, without replacing the machine
A 2.5- or 10-gigabit card or adapter speeds up one machine only if the switch matches. Five sold on Amazon.com, checked October 26, 2026.
