If the LED is light but the wireless LAN function is still faulty, the antenna may be damaged. Replace with a new antenna following the steps in Chapter 4, Replacement Procedures. If the problem persists, or if the wireless LAN LED is not light when the wireless communication switch is turned to “On”, go to Check 3.
