I also have a similar problem. And your solution works in some parts. Changing the channel from default is really time-consuming.
Though, if you want to try, follow these steps:
- Connect your PC or Mac to the Wireless Stick SSID in your WiFi settings
- Open your web browser and type www.sandisk.com/myconnect into the address bar
- Click on the Gear (setting icon) in the upper right corner
- Click the drop down menu beside Channel and select a channel other than default (if you continue to see random signal drops repeat changing the channel until a clear channel is found)
