Appendix B - Troubleshooting

Ensure your TCP/IP settings are correct.

Using DHCP

To use DHCP, select the radio button

Obtain an IP Address automatically

. This is the default

Windows setting. To work correctly, you need a DHCP server on your LAN.

Using a fixed IP Address ("Use the following IP Address")

If your PC is already configured for a fixed (specified) IP address, no changes are required.

(The Administrator should configure the Wireless Access Point with a fixed IP address from
the same address range used on the PCs.)
