1. connect your router to your laptop/pc with ethernet cable
2. it should automatically connect you to the internet under vista
3. now open a web browser (IE, fireforx or opera) and type in the address bar 10.0.0.200 (it will bring up the firmware software of your router)
4. in the first interface click setup wizard from the left
5. click next, select router/AP
6. click next, set your time
7. click next, select DHCP client as WAN access type
8. click next, do not change this and keep the default (default is Bandp 2.4ghz(B+G), WO: AP, Network type: Insfrustructure, SSID: Zoom, channel: 11)
9. click next, select WAP2(AES) as encryption, passphrase as pre-shared key, type a passphrase/password (write down these important information, u will need it later), click finished
10. open network and sharing centre (in vista), from the left select connect to a network (make sure your wifi switch is on)
11. you should see zoom, right click on it and select properties from the menu
12. go to security tab of this menu and select WPA2-personal as security type, and AES as encryption type (some XP do not support AES, in that case you will have to select TKIP, thn again you need to go back to step 9 and change the encryption type)
13. type you password exactly you typed in step 9 (CASE SENSITIVE), click ok

remove the ethernet cable, it should connect to internet wirelessly, if not try turning off the power of both the modem and router for 30-50 seconds. this will make them adapt to new setting.
