B-3: Other Problems

•Solve the preceding problem first.

•Are the IP address of the SMC2582W-B and the IP address of the client computer in the same IP subnet?

•If you cannot find any incorrect settings of the SMC2582W-B, the default gateway may be really down or there are other communication problems on the network backbone.

•The DNS server(s) of the client computer do not respond to ping from the client computer.

•Solve the preceding problems first.

•If you cannot find any incorrect settings of the SMC2582W-B, the default gateway of the SMC2582W-B may be really down or there are other communication problems on the network backbone.

B-3: Other Problems

•My SMC2582W-B has been set to obtain an IP address automatically by DHCP. How can I know its acquired IP address so that I can manage it using a Web browser?

•Use the SMC2582W-B Configuration Utility (WLBrwsr.exe) utility, which is included in the SMC2582W-B Installation CD.This utility can discover nearby SMC2582W-Bs and show their MAC addresses and IP addresses. In addition, it can launch the Web browser on your computer.

NOTE: On Windows 2000/XP, SMC2582W-B Configuration Utility can only be run by a user with administrator privilege.

NOTE: SMC2582W-B Configuration Utility does not scan the SMC2682W.
