Secure Your Home Wi-Fi Before Handling Sensitive Documents

Use this checklist to secure your home Wi-Fi before you look at, fill in or send sensitive documents from home. The Federal Trade Commission warns that others nearby who connect to an unprotected network might be able to see what you do online, including any personal information you look at or enter. The checklist takes the router and network steps from the Federal Trade Commission's consumer advice and puts them in an order a non-technical reader can follow, one setting at a time, with a short reason for each step. It does not test your router and does not replace your router manufacturer's own instructions. It is general information only, not advice about your own situation.

Step one: get ready

  1. Find the name of your router's manufacturer, because you need it to look up how to change the router's admin and Wi-Fi network passwords.
  2. Before you set up a new router or update your existing one, visit the manufacturer's website to see if a newer version of the router software is available for download, so your router stays up to date.
  3. Register your router with the manufacturer and sign up to get updates, so you hear about the latest version.
  4. If you got your router from your Internet Service Provider, check with the provider whether it sends out automatic updates, so you know how your router stays up to date.

Step two: change the default settings

  1. Change the default administrative username to something unique, because the admin side of the router is where its settings are changed.
  2. Change the router admin password, because a hacker who logged into the admin side could change your settings, including the Wi-Fi network password, and undo your other security steps.
  3. Change the Wi-Fi network password, the one your devices use to connect, because a unique and secure password prevents strangers from getting onto your network.
  4. Change the default network name to something unique, because the official advice lists the network name alongside the admin username and password.
  5. Keep your name, your address and your router brand out of every login name and password, as the official page advises.
  6. Make each new password long, aiming for at least 15 characters with uppercase and lowercase letters, numbers and symbols, or use a passphrase of random words, which follows the Federal Trade Commission's general password advice.
  7. If you cannot find how to change the passwords, search online for your manufacturer's instructions for the admin password and the Wi-Fi network password, and if you still have trouble, contact the manufacturer directly.

Step three: turn on encryption and the firewall

  1. In the router settings, choose WPA3 Personal or WPA2 Personal, because encryption scrambles the information sent through your network; WPA3 is the newer and best option, but both work.
  2. If the only options listed are WPA or WEP, update the router software and check again, because those older options are outdated and not secure.
  3. If WPA2 or WPA3 still does not appear, consider getting a new router, which the official page suggests to keep your information secure.
  4. Check that the router firewall is turned on, because it is an additional layer of protection that can help keep out viruses, malware and even hackers, and most routers come with one built in.

Step four: switch off convenience features

Some router features can be convenient but weaken your network security. Look for these three in your settings.

  1. Turn off remote management, because it lets the router's settings be changed over the internet.
  2. Turn off Wi-Fi Protected Setup (WPS), because it connects a device at the push of a button on the router instead of the Wi-Fi network password.
  3. Turn off Universal Plug and Play (UPnP), because it lets devices find each other on the network, which can make the network less secure.

Step five: give guests their own network

  1. Set up a guest network with a different name and password, so fewer people have your primary Wi-Fi password.
  2. Point visitors to the guest network, so malware a guest may unknowingly carry on a phone or tablet does not get onto your primary network and your devices.

Step six: finish and keep it secure

  1. Log out as administrator when you are done, because while you are logged in, passwords and security settings can be changed.
  2. Turn on automatic updates for your security software, internet browser, operating system and mobile apps, because updates often contain critical patches and protections against security threats.
  3. Secure your computer, phone and other devices too, because hackers can get to your network through unsecured devices.
  4. Turn on two-factor authentication for the accounts you use with sensitive documents, because a hacker who steals your password cannot log in without the second factor.

Before you open a sensitive document

  1. Look for a lock symbol or https in the address bar to the left of the website address, which shows the connection is encrypted.
  2. Remember that encryption alone does not prove a site is genuine, because scammers also create fake websites and encrypt them.
  3. Do not click a link in an unexpected email or text, and instead contact the company using a phone number or website you know is real.

What to do if something goes wrong

If you discover an issue, the official advice is to act quickly.

  1. If you think someone is using your personal information, go to IdentityTheft.gov to report it, because there you can get a personalized recovery plan.
  2. Report scammers to the Federal Trade Commission at ReportFraud.ftc.gov, because the Federal Trade Commission names that site for scam reports.

These official pages cover home routers, passwords and scams in general: they do not give the menus of a particular router model or address immigration paperwork itself.

Before you change settings, confirm the current advice on the Federal Trade Commission's page How To Secure Your Home Wi-Fi Network, and for help with the documents themselves, use the routes described in how to find authorized immigration help.
