How to fix "Slow Web Browsing"

Change your router's DNS settings to 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google) for an instant speed boost if pages hesitate before loading.

How to fix "Strict" or "Blocked" NAT

If your IoT NAT Type failed, try these steps in your home router (192.168.1.1):

  1. Enable UPnP (Universal Plug and Play) to allow auto-port routing.
  2. Change NAT Filtering from "Secured/Symmetric" to "Open".
  3. Call your ISP (CGNAT Issue): If on Mobile/Fiber, request a Static Public IP.
