Is anyone else getting fairly frequent and seemingly random disconnects? This is not IS Boxer specific, as I'm getting this while also one-boxing to level up a toon to 70th on a newer account.

The exact message is:

LOST CONNECTION
Your connection to the Battle.net service has time out.
Please log in again. (Code 3007)

OK




According to their knowledge base, ensuring that Windows Secondary Log-In is enabled can fix this issue.
Mine was set to 'Manual' and not 'Automatic', but changing this setting didn't make an issue.

Their second potential fix is to join a General Chat channel, so you're constantly getting messages from their server.
Again, no luck in solving the issue.
