To help with possible disconnects (this worked for me, and several friends with the issue)
1. Boot up the STO launcher.
2. Click the tab in the upper-right 'options'.
3. Use the drop down window under 'proxy'.
- Select either US or EU depending on your location.
4. click 'OK'
You'll get a pop up that warns you of possible disconnects. Ignore it. This got rid of my constant DC's issue completely. I hope it works for you as well.
Tip: Uninstall Pando Media Booster, after you're done installing and updating the game. This is a general rule of thumb for anything that uses that program. Pando is known to continue running in the background, sucking up bandwidth.
