Public Wi-Fi Safety: Look-Alike Networks and What Not to Do on Hotel and Café Wi-Fi

Free Wi-Fi at the café, hotel, airport or ballpark is handy. Most of the time it’s fine — especially now that almost all websites use encryption. But public networks come with a few risks worth knowing about, particularly for business owners checking email and banking on the road.

The main risks

• Look-alike networks. Anyone can set up a hotspot named “Main Street Cafe FREE.” If you connect to it, they can watch your traffic and redirect you to fake sign-in pages.
• Open networks (no password, no lock icon) don’t encrypt the connection between your device and the router.
• Captive portals that ask too much. A Wi-Fi sign-in page that asks for your email password or card number is a red flag.
• Auto-connect. Phones and laptops may silently join networks with familiar names.

Tips for safer public Wi-Fi

• Ask staff for the exact network name and password.
• Use your phone’s hotspot for banking, payroll and anything sensitive.
• Look for the lock icon / https in the address bar, and don’t click through certificate warnings.
• Turn off auto-join for public networks and “forget” them when you leave.
• Use a VPN for business work on the road. We can set one up that connects back to your office.
• Keep your device updated and its firewall turned on.

What about public charging stations?

USB charging ports in airports and hotels could, in theory, be tampered with to access data. Real-world cases are rare, but the fix is easy: use your own charger in a wall outlet, carry a battery pack, or use a charge-only cable. If your phone asks whether to “trust this device” when you plug in to charge, tap Don’t Allow.
