A reliable home network is built from a few interconnected pieces, each worth understanding on their own.
The core components
- Modem — connects your home to your ISP.
- Router — distributes that connection to your devices. See our router guide.
- Switches — add extra wired ports if needed.
- Mesh nodes or extenders — extend Wi-Fi coverage. See our mesh Wi-Fi guide.
A simple health checklist
- Confirm your actual speed matches your plan — see our speed guide.
- Check router placement is central and unobstructed.
- Prefer Ethernet for stationary streaming devices — see our Ethernet vs Wi-Fi comparison.
- Restart your router periodically.
