Solve the following problems in order:
z The wireless client cannot pass Web redirection-based authentication.
Are user name and password are correct?
Check the user credential information stored on the RADIUS server.
Is the RADIUS server correctly set up?
Check whether the password for the wireless client is stored using reversible encryp-
tion on the RADIUS server.
Check if the RADIUS server is set to use EAP-MD5, PAP, and CHAP authentication.
z The IWE3200-H does not respond to ping from the client computer.
Are two or more NICs (wireless or wired) installed on the client computer?
Use the OS-provided command-line network tool, route.exe, to modify the contents
of the routing table.
Use Windows-provided Device Manager to disable unnecessary NICs.
Is the underlying communication link established?
Make sure the wireless link is OK.
Make sure the Ethernet link between the AP and the IWE3200-H is OK.
Make sure the settings of the client computer and of the IWE3200-H match.
Are the IP address of the client computer and the IP address of the IWE3200-H in the same
IP subnet?
Use WinIPCfg.exe or IPConfig.exe to see the current IP address of the client com-
puter. Make sure the IP address of the client computer and the IP address of the
IWE3200-H are in the same IP subnet.
TIP: If you forget the current IP address of the Router, use Router/AP Browser to get
the information (see Appendix B-2).
z The default Router of the IWE3200-H does not respond to ping from the client
computer.
Solve the preceding problem first.
Is the modem working?
You may find out the answer by directly connecting the modem to a computer. Refer-
ring to the manual of the modem if necessary.
Are the IP address of the IWE3200-H and the IP address of its default Router in the same
IP subnet?
