3. Tap on "Configure IP - Automatic" to change it. You see 3 options:

Automatic
Manual          check
BootP

4. Tap on "Manual" to select it. You see manual setting details.

5. Enter your fixed IP address and other information:

ID Address      192.168.1.101
Subnet Mask     255.255.255.0
Router          192.168.1.0
