To renew your IP address, go to Start, Run and type CMD to open a new command prompt window. In later versions of Windows, just click Start and type in CMD.

Now type the following command:

ipconfig /renew

Release IP Address

To release an IP address, type in the following command:

ipconfig /release

That’s all there is to it.

Method 2: Change your default DNS

• Hit Windows key + R
• Type ‘ncpa.cpl’ into the newly-opened ‘Run’ window
• Find the network you’re having trouble with in the newly-opened selection window and choose ‘Properties’ via the right-click menu
• Go to the ‘Networking’ tab and then click on the ‘Settings’ button
• Select ‘Internet Protocol Version 4 (TCP/IPv4)’ and click on the ‘Properties’ button
• Select the ‘General’ tab in the new window, and then click on the ‘Use the following DNS server address’ toggle’
• Replace the ‘Preferred DNS server’ values with 8.8.8.8
• Replace the ‘Alternate DNS server’ values with 8.8.4.4

Afterwards, you’re going to want to do the same thing with ‘Internet Protocol Version 6 (TCP/IPv6), but use 2001:4860:4860::8888 as your Preferred DNS server, and 2001:4860:4860::8844 as your Alternate DNS server. In some cases, this will solve your problem.

Method 3: Disable UPnP

Disabling UPnP is more complex than ever. It is more difficult because you will have to access the configuration interface of your router, and this may be more difficult because turning it off may cause problems in games other than Battlefront 2.

You want to open your web browser and type “192.168.0.1” or “192.168.1.1” in the address bar. Anyone can work, depending on the brand and model of your router. You can find a large amount of router-related information at portforward.com, which we recommend checking before making changes to your device’s configuration.

With the router user interface open, log in to the device using the credentials provided by your ISP, then go to the “NAT redirection” section of the interface. The exact name may vary, but keep in mind that you’re looking for some kind of forwarding with a dedicated section for UPnP. When you find the relevant option, just deactivate it and see if the issue is resolved.
