Router & Wi-Fi Guide: Why Your Internet Feels Slow

What a router actually does

Think of your internet connection as a water pipe coming into your house. The router is the tap that spreads it to every device. A cheap router is a tiny tap — no matter how big the pipe, only a trickle comes out.

Wi-Fi generations, decoded

• Wi-Fi 5 (older): Fine for a small flat and a few devices.
• Wi-Fi 6: Handles many devices at once — the 2026 minimum for a family.
• Wi-Fi 6E / 7: Newer, faster, and less congested. Worth it for gigabit internet or heavy smart homes (20+ devices).

Range: the honest truth

One router covers about 1,000–1,500 sq ft with good signal. Walls, especially concrete, eat signal. For multi-floor or large homes, buy a mesh system (2–3 small units placed around the house) — it's the single biggest upgrade most homes can make.

Placement matters more than price

• Central, high, and open — not inside a cabinet or behind the TV.
• Away from microwave ovens and thick concrete walls.
• If your home office is far, run one ethernet cable or use a mesh node there.

Security basics everyone should do

• Change the default admin password (routers ship with public default passwords!).
• Use WPA3 or WPA2 security, never open/WEP.
• Update router firmware every few months — routers get hacked too.

Home vs office vs enterprise

• Home: Wi-Fi 6 router or 2-node mesh.
• Small office: Mesh or business access point; separate guest Wi-Fi for visitors.
• Enterprise: Multiple wired access points with a central controller — handled by IT, because 200 devices on one router collapses.

Bottom line

Before upgrading your internet plan, upgrade the router. A $100 Wi-Fi 6 router transforms a 200 Mbps connection more than paying for 500 Mbps.
