When I Try to connect to battle.net it says i may need to connect to the internet manually etc. I ran the diagnostic tool linked in these forums and its showing that i am ip banned. Though I don't know how that would be possible since I have never used any third party programs or invalid cd keys.

Also this problem has only been happening since i switched isps. I have configured my router/firewall and the portforward port checker tool says the needed port is open.

I would also like to note that the tool took a very long time just to get this far, about thirty minutes or so.
Here is the diagnostic tool info:

You are temporarily restricted. Unfortunately, we cannot tell you the exact reason as to why you have been restricted, or the amount of time you'll be restricted. The only thing we can show is the list of reasons for restrictions and give you a timeframe. Please note that restrictions cannot be removed or shortened, the only solution is to wait it out. You can view the thread below for more information about restrictions:
(http://forums.battle.net/thread.html?topicId=10972137363).

Now, there are different types of restrictions. First, there's the Realm Down message which only appears on Diablo2. This type of restriction lasts between 2 minutes and 12 hours. Next, there's the Temporary Restriction and the Extended Restriction. Temporary restrictions last anywhere from 2 minutes to 72 hours and Extended Restrictions last between 3 days and 2 weeks. If you would like to find out what type of restriction it is, send an e-mail to support@blizzard.com. Please note, it will take an employee 2-3 business days to respond to you.
