Where to start if you have never opened your router's settings

A sensible order for a first visit:

  1. Follow how to log in to your router once, just to see what your admin page looks like. Looking around does not change anything.
  2. Use the default router passwords table to sign in, then change the admin password. It is the single most useful security step for a home network.
  3. Next, change the Wi-Fi password to a long one of your own (12 characters or more) and make sure security is set to WPA2 or WPA3.
  4. To understand the equipment in your home, read modem vs router and what is an SSID. They give you the vocabulary for everything else.

Here for a specific problem, such as a login page that will not open, a forgotten password or a weak signal? Jump straight to the troubleshooting guides above.

Finding guides for your equipment

Device-specific instructions live in three hubs: router brands for routers you bought yourself, US internet providers for gateways from Xfinity, Spectrum, AT&T, Verizon Fios, Cox and T-Mobile, and router IP addresses if you only know the address your router uses.
