How to Boost Wi-Fi Speed Without Buying Anything 
Slow internet? Try these simple fixes before spending money:
Move your router to a central, open spot for better signal.
Change Wi-Fi channels in router settings to avoid interference.
Limit background apps that use data silently.
Restart your router weekly to refresh the connection.
Use 5GHz band if your device supports it — faster and less crowded.
Tip: Avoid placing your router near walls or metal objects!
