The￿wireless￿LAN￿antenna￿wire,￿wireless￿LAN￿unit￿or￿system￿board￿may￿each￿be￿the￿source￿

of￿a￿wireless￿LAN￿fault.￿Any￿of￿these￿components￿may￿be￿damaged.￿To￿determine￿if￿the￿

computer’s￿wireless￿LAN￿system￿is￿functioning￿properly,￿perform￿the￿following￿procedures.￿

Figure￿2-15￿outlines￿the￿process.￿Start￿with￿Procedure￿1￿and￿continue￿with￿the￿other￿

procedures￿as￿instructed.￿

Procedure￿1:￿ Diagnostic￿test￿

Procedure￿2:￿ Connector￿and￿replacement￿check￿

Procedure￿1￿ Diagnostic￿test￿

Run￿the￿Diagnostic￿Program,￿which￿will￿automatically￿execute￿the￿wireless￿LAN￿Device￿ check.￿Test￿and￿Diagnostic￿for￿more￿information￿PLS￿use￿windows￿application.￿

If￿an￿error￿is￿located,￿go￿to￿Procedure￿2.￿￿If￿an￿error￿is￿not￿located,￿the￿wireless￿LAN￿system￿is￿ functioning￿properly.￿

Procedure￿2￿ Connector￿and￿replacement￿check￿

The￿wireless￿LAN￿antenna,￿wireless￿LAN￿unit￿or￿system￿board￿may￿be￿disconnected￿or￿ damaged.￿￿Disassemble￿the￿computer￿following￿the￿steps￿described￿in￿Chapter￿4,￿Replacement￿ Procedures,￿and￿perform￿the￿following￿checks.￿

￿

Check￿1￿ Make￿sure￿that￿the￿wireless￿LAN￿antenna￿is￿firmly￿connected￿to￿the￿Wireless￿ LAN￿module￿(refer￿to￿Chapter￿4￿for￿instructions)￿and￿that￿the￿wireless￿LAN￿ module￿is￿securely￿slotted￿into￿the￿system￿board.￿If￿the￿problem￿persists,￿go￿to￿ Check￿2.￿

Check￿2￿ Check￿that￿the￿wireless￿communication￿switch￿is￿turned￿to￿“On”,￿and￿then￿make￿ sure￿that￿the￿wireless￿communication￿LED￿on￿the￿front￿panel￿is￿light.￿If￿the￿LED￿ is￿light￿but￿the￿wireless￿LAN￿function￿is￿still￿faulty,￿the￿antenna￿may￿be￿damaged.￿
