When you are connected direct, are ALL other devices off the network connection–just one cable between the DM0 and laptop? No switches even dangling off it?
Take a look at this post–it seems a security update/change in later versions of Android broke auto-discovery (or that’s how I read it). You’ll have to manually connect.
I also don’t use these much, as the band takes care of their mixes. However, it sounds like it could be the configuration needs saved in the ME-1…I’ll have to see what ours do when they get plugged in with power.
We’re having an issue where we had to temporarily replace our ME-U (to get repaired) with a switch and we are having a “pop” about every 30 seconds, too.
