Your last remark got me started to think 
The MusicLife app cannot be ruled out completely. The Arcam developer wants to obtain some information that could reveal the cause. This information contains the response the LinkSys is sending to the request MusicLife is making. He is investigating to create a MusicLife build with a save button. After you press this button the required information will be saved into a file. You have to send this file (PM it to me, I’ll forward it).
In order to get this build you have to be on the beta track. Are you already subscribe to Music Life beta builds? Refer to here how to get the build.
