Since the support can’t help you in the matter, I will. 5 days of fooling around and I decided to take matters into my own hands.
If you also have had issues logging into D2, or other games on the old Battlenet platform cannot connect to battlenet for no apparent reason. Don’t fret, we have a solution since blizzard will NOT assist you in the matter.
If this is your internet connection and you have access to the router / modem… This is solely for you.
1.Log into your router whatever brand it may be.
2.Jot down your current PUBLIC IP address
3.Unplug your cable modem
4.In the Advanced settings go to Setup
5.Locate your MAC address more than likely the setting will be, “use default MAC address” change the setting to “USE computer MAC address”
6.Apply the setting and allow the router to reboot and adjust the settings.
7.After this plug back in your cable modem and switch back to the main screen in your router settings to check the IP address, more than likely you will be assigned a new IP address because of the change in MACs
Voila!
Log into the game and have fun!
Enjoy never having the speak to the customer service.
