Preparation Note

Keep your current Wi-Fi network name and password handy before adjusting wireless settings inside your router web dashboard or mobile companion app.

01. Physical Placement & Band Selection (2.4 GHz vs. 5 / 6 GHz)

Higher-frequency 5 GHz and 6 GHz channels deliver fast gigabit throughput at close range, while 2.4 GHz signals travel farther through walls at lower speeds.

Workstations & Streaming → 5 GHz / 6 GHz · Smart Plugs & Distant Rooms → 2.4 GHz

Elevating your router on an open shelf rather than tucking it behind a television or inside a media cabinet noticeably improves room-to-room signal consistency.

02. Timed Power Cycling & DHCP Lease Refresh

When switching modems or refreshing an internet gateway connection, powering equipment back on in sequence ensures proper IP address negotiation.

Power Sequence → Modem / ONT First (Wait until Online LED is solid) → Router Second

Waiting 60 seconds before reconnecting power allows upstream gateway sessions to reset cleanly.

03. Enabling Encrypted DNS-over-HTTPS (DoH)

Windows 11 and modern browsers support encrypted DNS lookups, improving lookup privacy and responsiveness on congested networks.

Settings → Network & internet → Wi-Fi → Hardware properties → DNS server assignment

Select DNS-over-HTTPS (On - automatic template) when configuring well-known public resolvers such as Cloudflare (1.1.1.1) or Google Public DNS (8.8.8.8).

Additional Reference Note

Consult your internet service provider app or gateway manual if fiber optical or cable signal indicators remain dark.
