Hey mocha, hope I'm not interfering.

Domain Name Server (DNS) Address choose Get Dynamically From ISP

Under ADSL Settings:

VCI enter 35

Under Wireless Settings:

Name (SSID): choose what you want to call your network
Channel: I have channel 11

Wireless Access Point:
Tick Enable Wireless Access Point

Security Options

Secure your network. Do not choose Disable. WEP is ok, not great and can be cracked by your neighbors. Choose WPA-PSK (Wi-Fi Protected Access Pre-Shared Key) or WPA-802.1x

Hope this helps.
