Langkah pertama, Hitung IP (Subnetting) :
IP ADDRESS : 128.168.1.3/27
SUBNET : 255.255.255.224
Binary of IP ADDRESS
10000000.11000000.00000001.00000011     IP ADDRESS    128.168.1.3
10000000.11000000.00000001.00000000     Network           128.168.1.0
10000000.11000000.00000001.00000001     First Host IP     128.168.1.1
10000000.11000000.00000001.00011110     Last Host IP     128.168.1.30
10000000.11000000.00000001.00011111     Broadcast         128.168.1.31
*Red : bits of Network number
*Blue : bits of Host number
Buka Cisco Packet Tracer untuk membuat desain wlan nya :
-          - Letakkan beberapa PC pada layer, dalam video tersebut ada 5 PC sebagai contoh
-          - Pasang Switch, LinkSys, dan access point sebagai pendukung periferal jaringan.
-          - Tambahkan laptop (5) untuk mengakses wifi
-          - Hubungkan setiap PC ke switch menggunakan kabel stright.
-          - Hubungkan Switch ke LinkSys menggunakan kabel Cross dan hubungkan LinkSys ke Access Point menggunakan kabel Straight.
Mengaplikasikan IP hasil subnetting :
-          - Beri nama komputer dengan IP address yang sesuai agar lebih mudah dalam penentuan IP pada setiap komputer (sesuai contoh dalam video).
-          - Klik pada komputer untuk konfigurasi IP, pilih desktop tab, Ip Configuration panel untuk mengkonfigure IP komputer. Isi Tetx field sesuai dengan Range IP yang telah dihitung. Dan lakukan cara tersebut pada masing-masing PC dengan IP yang berbeda tentunya.
Setting LinkSys (Wireless Router) :
-          - Klik LinkSys, klik tab GUI, kemudian isi IP address Router sebagai Gateway (pintu gerbang keluar masuk data).
-          - Tentukan start IP Address, hal ini berfungsi untuk memanagement IP address saat menggunakan DHCP setting
-          - Klik Wireless tab untuk mengganti SSID wireless, hal ini dilakukan agar PC/laptop yang akan menggunakan mengetahui ID wireless tersebut jika akan mengunakan. (contoh : Wireless). Close dialogbox.
-          - Beri nama LinkSys agar lebih mudah dikenali.
Accsess Point : 
Access poin berfungsi sebagai repeater atau sebagai penguat sinyal wireless,
Setting SSID AP (contoh : Access Point)
Setting laptop agar dapat terhubung ke wireless :
-          - Klik laptop, matikan power laptop, ganti Lan card dengan Wireless Card, tekan kembali tombol power untuk menghidupkan laptop. Lakukan hal yang sama pada masing – masing laptop.
-          - Untuk mengkoneksikan laptop dengan wireless yaitu dengan cara : Klik laptop, pilik Desktop tab, pilih PC Wireless panel, pilih connect tab, tunggu beberapa saat hingga wireless (SSID) terdeteksi, kemudian pilih wireless yang akan digunakan, klik connect (sesuai video tutorial).
-          - Biarkan laptop dengan settingan DHCP pada IP configuration agar laptop secara otomatis menyesuaikan IP Addressnya.
Test konektifitasnya, caranya :
-         - Klik salah satu PC/laptop ex: komputer 1 dengan IP Address 128.168.1.1
-          - Pilih desktop tab
-          - Pilih command promp
-          - Ketik : ping IP Address PC/laptop lain ex : ping 128.168.1.9
-          - Tekan enter
-          - Replay, berarti antar PC dan laptop sudah saling terkoneksi.
Selesai, semoga paham :)
