WLAN troubleshooting

Introduction to WLAN troubleshooting

The main problem that can occur is malfunction in WLAN or WLAN ASICs or WLAN SMD components. Such

problems are unpredictable and may have many causes, either HW or SW related.

Note: When WLAN ASIC or WLAN/BTH front-end-module is changed, WLAN tuning is required. WLAN

tuning is also required when permanent memory is replaced or corrupted. See tuning instructions

for more information.
