How to Fix Slow WiFi on Any Device

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.
