Quick Questions

Shade in the A or B circle for each question.

1. Which Wi-Fi network is safer to use at home?

A A network secured with WPA3 and a strong password

B An open network with no password

2. What does WPA2 or WPA3 do to the data sent through the air?

A It makes the data travel faster through the walls

B It scrambles the data (encryption) so outsiders can't read it

3. Which is the newest Wi-Fi security standard?

A WPA2

B WPA3

4. You just plugged in a new router. The default password is printed on its label. What should you do?

A Change the default router password to a strong, unique one

B Leave it, because the manufacturer's password is already the safest

5. Which Wi-Fi password is the better choice?

A Three random words and some numbers, like purple-koala-bike-72

B 12345678

Answer Key

Securing a Wi-Fi network

Section A: Quick Questions

A — A network secured with WPA3 and a strong password

B — It scrambles the data (encryption) so outsiders can't read it

B — WPA3

A — Change the default router password to a strong, unique one

A — Three random words and some numbers, like purple-koala-bike-72

Section B: Match the Pairs

WPA3 → The newest Wi-Fi security standard, which scrambles data in the air so outsiders cannot read it

Open network (no password) → A Wi-Fi network with no protection, so anyone nearby can join and data may be read

Changing the default router password stops strangers from logging in to your router settings with a well-known password → Router admin password: admin -> Tr4in!Lamp#Hill92

Choose the strongest security setting on your router: WPA3 if available, otherwise WPA2 → Wi-Fi security: WPA3 (or WPA2)

Wi-Fi security: None (open network) → No password or encryption is set, so anyone can join and read data. Fix: turn on WPA2 or WPA3 with a strong password.

Router admin password: admin (unchanged) → The default password is public knowledge and easy to guess. Fix: change it to a strong, unique password.

Section C: Definitions

WPA3 — The newest Wi-Fi security standard. With a strong password it scrambles data in the air so outsiders can't read it. WPA2 is the older version. Open networks have no protection at all.

Section D: Fill in the Blanks

Network: HomeWiFi
Security: WPA3
Password: strong

Network: CafeFree
Security: Open
Password: none

Router admin login:
Change the default password
Use a strong, unique one

Network: GranHouse
Security: WPA2
Status: older but still secure

Wi-Fi encryption scrambles data in the air

Section E: Spot the Error

C — A secured Wi-Fi network needs encryption turned on so data in the air is scrambled. The line should be encryption = True.

A — An open network has no protection, so anyone nearby can read the data. The security should be a standard such as WPA3 (or WPA2).

D — On a secured network (WPA2 or WPA3) the data is scrambled so outsiders cannot read it. The message should say the data is scrambled.

D — A network is only secure when it is NOT open. The test should use != so WPA2 counts as secure, not ==.

C — If the router supports WPA3, use it because it is the newest and safest standard. Setting it to OPEN would remove all protection.
