Your router can change its internal DNS and IP configuration at will based on the firmware update provided. If your on wifi this can be tested by plugging it in directly to the router. If that is not an option you can power cycle and reset the firmware at the same time as resetting your license agreement. I had to do this when taken king dropped and I've been on since day 1 launch. Most routers also have an option to port forward for gaming. These are preset in the router but need to be activated. This will also give you a much higher connection and a better NAT type. Who is your Internet provider? I can tell you how.
