Router Reservation (Recommended)

Best for venues — leave Host PC on DHCP, but router always gives it the same IP. No manual IP on PC, phones never break.

Works on TP-Link, IndiHome, ZTE, Huawei, etc.:

1. On Host PC, find MAC address: cmd → ipconfig /all (Windows) or ip link (Linux) → Physical Address like A4:CF:12:8B:33:01.

2. Open router admin: browser → 192.168.1.1 (or 192.168.0.1 / 192.168.100.1 — check sticker). Login (admin/admin or sticker).

3. Go to DHCP → Address Reservation (or LAN → DHCP → Static Lease / IP & MAC Binding).

4. Add: MAC A4:CF:12:8B:33:01 → IP 192.168.1.50 → Enable → Save. Reboot router or reconnect Host WiFi.

5. Verify: disconnect/reconnect Host → ipconfig should still be 192.168.1.50.
