Release and renew the IP configuration
Regardless of what type of addressing your computer used
originally, it will now obtain this information from the SOHO
using DHCP. To enable your computer to receive this information
from the SOHO, you must force it to release and renew its IP
configuration information.
From your computer desktop:
1 Click Start => Programs => Command Prompt .
2 At the C:\ prompt, type winipcfg . Press Enter.
The IP Configuration dialog box appears.
3 Verify that the information is displayed for "Ethernet Adapter,"
not for "PPP Adapter," which applies to a dial-up telephone
modem.
4 Click the Release button. Then click the Renew button.
Your IP Configuration should look similar to the image below. The values
in the IP Configuration dialog box were obtained from the SOHO itself.
The IP Address, Subnet Mask and Default Gateway entries must be
completed and have the values displayed for address sharing to work as in
the example below.
