Steps:

1. Settings → Network & Internet → Ethernet (or Wi-Fi if on WiFi). Click your connected network.

2. Edit next to IP assignment → Change Automatic (DHCP) → Manual → toggle IPv4 ON.

3. Fill:

   • IP address: 192.168.1.50 (pick a free one — .50 is usually free. Check router's DHCP range first)
   • Subnet mask: 255.255.255.0
   • Gateway: 192.168.1.1 (your router — often printed on router sticker)
   • Preferred DNS: 192.168.1.1 (or 1.1.1.1)
   • Alternate DNS: 8.8.8.8 (optional)

4. Save → no reboot. Test: open cmd → ipconfig → should show 192.168.1.50.

How to find Gateway / free IP:

• Gateway: cmd → ipconfig → Default Gateway line.
• Free IP: in router admin 192.168.1.1 → DHCP → see used IPs, pick outside range or use the app's banner after change (it tells new IP).

Undo: Set back to Automatic (DHCP) anytime.

When you change IP, re-scan QR: Host Overview will show banner Host IP changed — Was .23 → now .50. Re-scan QR → show QR again → phones re-pair (30s).
