Wi-Fi & routers

VPN won't connect from home Wi-Fi

A VPN that won't connect at home usually points to a firewall or router setting blocking VPN traffic, an incorrect server or credential setup, or a conflict with another VPN or security app running at the same time.

Symptoms

  • VPN app shows 'connecting' indefinitely then times out
  • VPN connects on cellular data but not on home Wi-Fi
  • Error message references a blocked port or failed handshake
  • VPN worked before and stopped after a router change

Likely causes

  • CommonRouter blocking VPN protocol portsSome routers have a 'VPN passthrough' setting that needs to be enabled for certain VPN protocols to work.
  • PossibleDouble NAT or restrictive firewall on the routerComplex network setups can interfere with the VPN's ability to establish a tunnel.
  • PossibleOutdated VPN app or expired login credentialsVPN services update their apps and servers regularly; an old version may fail to connect.
  • PossibleAnother VPN or proxy service running simultaneouslyConflicting network software can block a VPN from establishing its own connection.

What to do

  1. Restart the device and try connecting to the VPN again, since a stuck network process can block it.
  2. Check the router's settings for 'VPN passthrough' (like PPTP, L2TP, or IPsec passthrough) and enable it if disabled.
  3. Try switching the VPN app's protocol setting (e.g., from IKEv2 to OpenVPN or WireGuard) since some routers block specific protocols.
  4. Confirm your VPN subscription is active and credentials are current by logging into the VPN provider's website.
  5. Update the VPN app to its latest version.
  6. Temporarily disable any other VPN, proxy, or ad-blocking network extension running on the same device.
  7. If it connects fine on cellular data but never on home Wi-Fi, contact your router manufacturer's support or your ISP, since some routers or ISPs restrict VPN traffic.

When to call a pro

If a business or corporate VPN specifically won't connect from home, your company's IT department may need to whitelist your connection or adjust firewall rules.
