Public WiFi options include 'VPN' or 'Travel Router+VPN'.
I explored ways to safely use public WiFi while studying on campus. There are two main approaches: one relies solely on a VPN on your device, and the other uses a travel router paired with a VPN. The latter is popular because it allows you to connect multiple devices at once, keeps everything on a private network, and avoids limits on VPN or WiFi connections. I’m still unsure why some people think a travel router alone adds real security benefits compared to just using a VPN. It seems unclear if having the router physically present offers extra protection in this setting. For your situation—just connecting one device at a time—I’d focus on understanding the specific security advantages of the travel router setup versus a standard VPN. Also, consider general tips like avoiding public networks when possible, using strong passwords, and keeping your device updated. Let me know if you want more advice!
To navigate between hotel lobbies, cafés and similar spots, using a VPN appears to be the most practical choice—no need to lug extra gear and you avoid splitting bandwidth across multiple devices behind your router. In more stationary settings, like staying at a hotel, I personally use my own Mikrotik router for better control and monitoring. It lets me filter traffic, set up routes, and manage resources efficiently (I’m using an SDWAN setup with zero-trust for remote access). Connecting all devices through one router is simpler than managing each individually.
The actual security depends on the VPN you choose—protocol, hosting location, and router configuration matter. A poorly set-up router can be more vulnerable than a mobile device acting as a client on a public network. Some VPNs have connection leaks, meaning traffic isn’t always fully rerouted through the tunnel. iOS has had issues with this in the past, though it’s unclear if fixes exist.
I prefer VPNs that use Wireguard or OpenVPN for stronger protection. NAT helps mask devices behind your router’s public IP, making it harder for outsiders to reach them unless ports are open. Combining NAT with a firewall and network monitoring provides extra security.
Keep your Wi-Fi settings randomizing MAC addresses and opt for password-protected networks with WPA3. After setting up your devices and router, create a test environment to check for sniffing or open ports. Ensure your firewall is correctly configured, keeping only necessary traffic in and out, and keep all software updated.
In short: a VPN can suffice for most users. If you go the self-hosted path, it’s safer if done right, but might be less convenient and could impact speed.
P.S. If you decide to buy a router, focus on securing it properly—otherwise, skip it here.
