The only way i can play without dropping out is to play with other people.
Have you tried joining General chat? That seems to resolve the 3007 disconnections for many. The error is a generic 'connection lost' error, so there could be any number of causes. For people disconnecting within the first 5-10 minutes and very consistently, joining General chat seems to be a successful workaround.
For those people it looks to be an issue with how the game sends data, and how some specific routers work with it (or in this case, don't). It's likely a router support issue we can attempt to mitigate from our end, but it'd be through a patch at some undetermined point in the future. What we need to do now, and ask for your assistance in, is troubleshooting the issue from the user end to try to find a workaround in the mean time.
If joining General chat does not resolve it, again, it's going to be a process for our tech support team to work with you and try to find the cause for your issue. [url="http://www.battle.net/support"]Battle.net/support[/url]
Well if anyone has problems with connections to the game, what would help is to list all UDP/TCP ports for players to have open. Make sure the ports are able to send and receive data, portforward.com is a very useful site.
Secondly, if you're on wireless - try cabled instead.
If the problem still persists it's either your ISP blocking some of theese ports, or, most likely your router causing the problems. If you have the possibility, try a different router/modem.
I've had a friend (and others) with similar problems in a different game. Playing cabled was better, but still didnt fix the problems. Switched to a different router and problems where gone.
It might be the same as i guess the problem is with that game. Different information are sent through different ports, you can connect and so but when some data are sent or trying to be received through a blocked port the Blizzards servers recognizes that client disconnected.
So - if you know the ports required to be open - post them here (and this should already have been done with a blue post!). Not sure if this is helpful for anyone but i hope someone will at least find a solution.
