Appendix B: T roubleshooting Check the following first: • Mak e sure that the pow er of the SMC2582W-B is on and the Ethernet cables ar e connected firmly to the RJ-45 jacks of the SMC2582W-B . • Mak e sure that the LED AL V of the SMC2582W-B is blinking to indica te the SMC2582W-B is wor kin g.
For a w ire le ss client computer to communica te with a corr espondent host on the Internet by the host’ s domain name (e.g. http://www .wi-fi.com), it first sends a DNS request to a DNS server on the Internet. The DNS request trav els first to the AP , then the AP relays this request to the default ga te- way of the client computer .
• So l v e the preceding pr oblem first. • Ar e the IP address of the SMC2582W-B and the IP addr ess of the client computer in the same IP subnet? • If y ou cannot find any incorr ect settings of the SMC2582W-B, the default gatew ay may be rea ll y d own or there are other communica tion problems on the network backbone .
• My SMC2582W-B stops working and does not respond t o W eb management requests. • The firmwar e of the SMC2582W-B may be stuck in an incorr ect state. • Unplug the power c onnector from the power jack, and then re-plug the connector to re star t the SMC2582W-B.
