1. Update your WiFi driver
Device Manager → Network Adapters → right-click your WiFi adapter → Update driver. Outdated drivers are the #1 cause of random disconnections. Visit your laptop manufacturer's website for the latest driver.
2. Change your WiFi channel
Log into your router (usually 192.168.1.1 or 192.168.0.1) → Wireless settings → change channel. Use a WiFi analyzer app (WiFi Analyzer on Android or inSSIDer on PC) to find the least congested channel in your area.
3. Disable WiFi adapter power saving
Device Manager → Network Adapters → right-click WiFi adapter → Properties → Power Management → uncheck 'Allow the computer to turn off this device to save power'. This prevents Windows from disconnecting WiFi when idle.
4. Flush DNS and reset TCP/IP
Open Command Prompt as Administrator and run these in order: ipconfig /flushdns → netsh int ip reset → netsh winsock reset → then restart your PC.
5. Update router firmware
Log into your router's admin panel → Advanced or Administration → Firmware Update. Outdated router firmware causes stability problems and security vulnerabilities. Check manufacturer's site if auto-update isn't available.
6. Check for interference
Microwaves, cordless phones, baby monitors, and neighboring networks all cause 2.4GHz interference. Switch to 5GHz band for a cleaner signal (shorter range but faster and less congested).
If disconnections persist after all these steps, the issue may be with your ISP, modem, or network infrastructure. We can run a full remote diagnostic to identify the exact cause.
