Before you start
- A laptop
- A VPN (recommended)
Method 1 Set Windows to Public mode
-
Step 1: Open network properties
Connect, then go to Settings > Network & internet > Wi-Fi > [network] properties.
-
Step 2: Choose Public
Set Network profile type to Public network (Recommended). This hides your PC from others and turns off sharing.
-
Step 3: Check the firewall
Open Windows Security > Firewall & network protection and make sure Public network firewall is On.
Method 2 Protect your traffic
-
Step 1: Use a VPN
Connect to a reputable VPN before browsing. It encrypts everything between your laptop and the VPN server.
-
Step 2: Stick to HTTPS
Check for the padlock and https:// in the address bar. Modern browsers can enforce it: Chrome Settings > Privacy and security > Security > Always use secure connections.
-
Step 3: Turn on two-step verification
Even if a password is stolen, 2-step verification protects your accounts.
Method 3 Avoid fake hotspots
-
Step 1: Verify the name
Ask staff for the exact network name. Attackers create look-alike networks (“Airport_Free_WiFi”) called evil twins.
-
Step 2: Don’t install anything
Legitimate portals never require you to download software or enter card details for “free” Wi-Fi.
-
Step 3: Forget the network after
Turn off Connect automatically and forget the network when you leave.
Troubleshooting
VPN won’t connect on hotel Wi-Fi
Sign in to the captive portal first, then connect the VPN. Some networks block VPN ports; try a different protocol in your VPN app.
Frequently asked questions
Is public Wi-Fi safe with HTTPS?
HTTPS protects the content of what you send, which covers most risks. A VPN adds protection for everything else and hides which sites you visit.
Is a password-protected café network safe?
Everyone with the password shares it, so treat it as public.
Summary
Set the network to Public, keep the firewall on, use a VPN and HTTPS, and confirm the network name to avoid fake hotspots. Use your phone’s hotspot for sensitive tasks.
