There are several possible reasons for that:
1. Your Wi-Fi signal is weak or doesn’t extend far enough. Wi-Fi connections can easily drop when the connected device is located near the edge of your network’s wireless signal range. The further away you get, the more unstable a Wi-Fi connection can get. Relocating your devices closer to your router is one way to solve this issue.
2. You’ve got too much wireless interference. You router isn’t the only device in your house emitting a signal. Several household items like Bluetooth devices, microwaves, TVs and cordless phones are pumping out radio signals that can interfere with your Wi-Fi network signal when they are in use. Moving your router away from devices like these is an easy solution.
Please note that an ideal position for a speaker is about 2-10 meters with a clear line-of-sight to the router. Having the router too close will cause interference. If you don’t have a chance to make an surrounding environment more suitable for stable Wi-Fi connection (e.g. move the router closer to the speaker or change location to avoid interference), we would suggest to use wired connection instead.
