Optimize Router Settings
Default router settings are often suboptimal for stability.
Router Optimization Wizard
Open browser → Enter 192.168.1.1 (or your router’s IP) → Login with admin credentials
Wireless settings → Channel → Change from Auto to 1, 6, or 11 (2.4GHz)
Advanced → QoS → WMM → Disable (if experiencing random drops)
Critical Router Settings for Stability:
Fix IP Address Conflicts
IP address conflicts can cause random disconnections for specific devices.
Method A: Static IP Assignment
Network settings → Change adapter options → Right-click WiFi → Properties → TCP/IPv4 → Use following IP address
Method B: Router DHCP Configuration
Router admin → LAN settings → DHCP Server → Increase range (e.g., 192.168.1.100 to 192.168.1.200)
DHCP Reservations → Add device MAC address → Assign permanent IP
💡 Common IP Conflict Scenarios
Multiple routers: Two routers with same IP range (both 192.168.1.x)
Manual IP assignments: Devices with manually set IPs within DHCP range
Network expanders: WiFi extenders creating separate IP ranges
Virtual machines: VMs with bridged networking causing conflicts
