Try the following when encountering an issue with the wireless access point connection:
- Move the subwoofer closer to the main unit of the home theater.
- If possible, place the subwoofer where it is not directly blocked by any furniture, walls, or metal barriers.
- Move your wireless access point (wireless router) more than 1 m away from the main unit, subwoofer, or sound speaker.
- If the wireless access point (wireless router) that you use can switch between 2.4 GHz and 5 GHz frequency bands, try changing the frequency of the wireless access point to avoid interference.
- For HT-ST9, HT-ST5, HT-NT3, HT-RT5: Try changing the wireless router to the 2.4 GHz band
- For HT-CT780, HT-CT380, HT-NT5, HT-CT790, HT-CT390: Try changing the wireless router to the 5 GHz band
- When using a wireless access point (wireless router) that can fix the channel, change the channel setting of the router to a frequency band shown above and check if the issue will improve. If it has improved, fix that channel.
NOTES:
- To change the wireless channel, refer to the operating instructions of the router.
- If the setting procedure of the router is unclear, it is recommended to turn off the power of the router. The router may automatically select another channel when it turns back on.
