Slow WiFi affects every device in your home. Before blaming your ISP, try these proven optimization steps that can double your wireless speed.

Router Optimization

1. Restart router: Unplug for 30 seconds (fixes memory leaks and channel congestion) 2. Channel selection: Use WiFi Analyzer app to find the least congested channel. Switch to it in router settings 3. Band selection: Use 5GHz for nearby devices (faster) and 2.4GHz for distant devices (better range) 4. Firmware update: Check router manufacturer website for latest firmware

Placement Matters

• Place router in central location, elevated (shelf or wall mount) • Away from microwaves, cordless phones, baby monitors • Not inside cabinets or behind TVs • Use mesh WiFi system for large homes (>1000 sq ft)

Device-Level Fixes

Phone: Forget and reconnect to WiFi. Reset network settings. Laptop: Update WiFi driver. Disable VPN/proxy. Run netsh winsock reset. Smart TV: Use 5GHz band or Ethernet cable for streaming.

When to Upgrade

If your router is 3+ years old and doesn't support WiFi 6, upgrading can significantly improve speed, range, and device handling. Xigox offers networking setup services starting at ₹999.
