How to choose a Wi-Fi router
Your router guards every device on your home network, so security updates matter as much as speed. Pick a Wi-Fi standard your devices can use, plan coverage for your home's size and walls, and change any default password on day one.

Common mistakes
Myths vs facts

FAQ
Wi-Fi Routers: common questions
Do I need mesh Wi-Fi?
If one router leaves dead zones in a larger or multi-floor home, mesh or wired access points help. Small flats often do not need it.
Should I use the router from my provider?
It can be fine if it gets updates. Your own router gives more control but check compatibility first.
How do I secure my router?
Change default passwords, keep firmware updated, use WPA3 or WPA2, and turn off remote management you do not need.
