Hi Brian, Thanks for taking the time to post of the forum. I apologize that you’re having these issues with your SoundTouch system, and I think we can solve this problem.
I’ve seen this issue before where systems with Wi-Fi cannot be detected by a computer that is connected with ethernet, and vice-versa. A lot of times, this can be solved with a simple settings change in your router. Typically, it will be called “Wireless Isolation” or “AP Isolation”. We want to make sure this is disabled. Apply the setting, power cycle the router, and this should hopefully solve the issue.
If the issue persists, please reply back with the Brand and Model number of your router so I can take a deeper look into the settings menu.
