Apakah anda tahu bahwa Anda bisa me-setup jaringan Wireless Adhoc untuk menshare koneksi internet di rumah tanpa harus menggunakan router atau switch?? Tentu saja anda bisa. Anda juga bisa menggunakannya untuk men-share file atau printer antara 2 atau lebih komputer dengan jaringan wireless. Perlu diketahui bahwa Anda bisa mempunyai 9 jaringan, dimana komputer bisa mengirimkaan data secara langsung satu sama lain. Kelemahan dari jaringan ini adalah jangkauannya yang terbatas. Anda akan perlu router wireless atau akses poin untuk jangkauan jaringan wireless yang lebih luas.

Alokasi Alamat IP

Anda bisa mengalokasikan alamat IP untuk setiap komputer yang masuk ken jaringan Ad-hoc wireless. JIka Anda menggunakan 3 komputer, Anda bisa dengan mudah meng-assign 192.168.0.1, 192.168.0.2,192.168.0.3 ke masing-masing komputer dengan netmask 255.255.255.0.

Catatan : Jika Anda mempunyai Internet Connection Sharing yang di-enable pada host komputer, Anda bisa men-setup komputer klien untuk mendapat alamat IP secara otomatis, kemudian komputer-komputer tersebut akan bisa mengakses ke Internet.

Konfigurasi  Komputer Host

• Klik Start  -> Control Panel -> Network Connections.
• Klik kanan pada wireless network connection, lalu klik Properties

• Pada Wireless Network Connection Properties, klik tab Wireless Networks.
• Klik Add pada bagian Preferred networks.

• Selanjutnya isilah Network Name (SSID) untuk jaringan yang akan Anda buat.
• Jangan lupa untuk mencentang check box This is a computer-to-computer (ad hoc)network: wireless access point are not used.
• Anda juga dapat membubuhkan WEP Password agar koneksi anda aman.

• Klik  OK dan OK lagi untuk menyimpan konfigurasi Anda.

Konfigurasi Komputer Klien

Windows XP otomatis akan mendeteksi jika ada Wireless Network yang aktif

• Klik kanan pada icon Wireless Network yang berada pada taskbar, lalu klik View Available Wireless Networks.

• Wireless Network Connection akan menampilkan list SSID wireless anda. Klik SSID wireless Anda lalu klik Connect .

Jika pada komputer host , Anda bubuhkan WEP Password maka windows XP meminta anda untuk mengisi password sebelum anda terkoneksi ke jaringan Ad Hoc Anda.

Update:
Untuk Windows XP yang tidak mempunyai DHCP Server service, user  harus  meng-assign alamat  IP secara manual, baik yang broadcast maupun client  yang terkoneksi .
