UK households depend on Wi-Fi for work, school and streaming. Unfortunately, many routers still keep default passwords and legacy settings. This guide shows how to improve Wi-Fi security with modern encryption, segmentation and a reliable VPN — and links to our in-depth articles for each step.
Why Wi-Fi security matters
Without strong encryption, nearby attackers can sniff packets or clone your SSID (evil twins). Start with the basics: What is a VPN? — it explains why VPN encryption complements router security.
Harden the router (checklist)
- Change admin credentials and enable 2FA if available.
- Update firmware quarterly; vendors silently patch critical bugs.
- Disable remote management (admin from LAN/VPN only).
- Prefer WPA3 (WPA2-AES as fallback). Need help on router setup? See VPN on your router.
- Turn off WPS — it enables offline PIN brute-force.
- Lock DNS and consider DoH/DoT on devices.
- Back up configuration once hardened.
Segment your network: Main, Guest and IoT
Smart TVs and cameras lag on patches. Keep them away from laptops/workstations. At minimum, enable client isolation for Guests. For step-by-step public hotspot safety read VPN on public Wi-Fi.
DNS safety & phishing
Attackers may change your DNS to malicious resolvers. Manually set DNS on the router and enable DoH/DoT on devices. For a simple on-device checklist see Wi-Fi security checklist.
How VPN strengthens Wi-Fi security
VPN encrypts traffic, masks your IP and mitigates MITM attacks on hotspots. Combine hardened router settings with a reputable VPN. Compare options in Free vs Paid VPN and avoid services that monetise data. For power-users: Kill Switch and Split Tunneling add extra control.

Performance & privacy tips
Use nearby UK/EU servers for lower latency. If streaming apps detect your location, clear cookies and reconnect. Curious about alternatives? See Proxy vs VPN — but note that only VPN provides end-to-end encryption.
Quick checklist
- Admin password changed; 2FA if available
- Firmware updated; auto-updates on
- Remote management disabled; LAN/VPN only
- WPA3 (or WPA2-AES); WPS off
- Guest & IoT isolated; firewall limits east-west traffic
- DNS set + DoH/DoT; watch for leaks
- VPN active on public Wi-Fi; consider router profile
- Config backup exported
