Procedure￿2￿ LAN￿connection￿check￿

The￿LAN￿cable￿may￿be￿damaged￿or￿the￿connections￿may￿be￿loose.￿Perform￿Check￿1:￿

Check￿1￿ Make￿sure￿LAN￿cable￿is￿firmly￿plugged￿into￿both￿the￿LAN￿set￿and￿the￿LAN￿port￿ of￿the￿computer.￿If￿the￿cable￿is￿connected￿correctly,￿go￿to￿Check￿2.￿

Check￿2￿ Make￿sure￿the￿LAN￿port￿is￿firmly￿secured￿to￿the￿system￿board￿of￿the￿computer.￿If￿ the￿malfunction￿remains,￿go￿to￿Check￿3.￿

Check￿3￿ The￿LAN￿cable￿may￿be￿damaged.￿Replace￿with￿a￿good￿cable.￿If￿the￿malfunction￿ remains,￿go￿to￿Procedure￿2.￿

Procedure￿3￿ LAN￿set￿check￿

The￿LAN￿set￿may￿be￿faulty.￿Perform￿Check￿1:￿

Check￿1￿ Try￿using￿the￿set￿for￿LAN￿reception.￿If￿it￿does￿not￿work,￿the￿set￿may￿be￿damaged.￿ If￿the￿set￿does￿work,￿perform￿Check￿2.￿

Check￿2￿ Try￿connecting￿a￿different￿LAN￿cable￿to￿the￿computer.￿If￿the￿replacement￿LAN￿ cable￿works,￿the￿original￿set￿may￿be￿damaged.￿If￿the￿replacement￿set￿does￿not￿ work￿the￿system￿board￿may￿be￿damaged.￿Replace￿it￿with￿a￿new￿one￿following￿the￿ instructions￿in￿Chapter￿4.￿
