Hi, Rick B.1
Welcome to Microsoft Community.
We understand that you are experiencing problems with an incorrect IP address, and to change your IP address you have a few options depending on whether you are connecting to the Internet via Wi-Fi or Ethernet. Here is how to change your IP address:
1. Reboot the router:
○ Turning the router off and on will sometimes provide you with a new IP address.
○ Unplug the router from the power source, wait a few seconds, and then plug it back in.
2. DHCP Issuance and Renewal:
○ In Windows 11, you can release and renew your IP address by going to Network and Sharing Center.
○ In Network and Sharing Center, click “Change Adapter Settings” on the left side.
○ Right-click your Wi-Fi or Ethernet connection, select “Properties”, and then click “Internet Protocol Version 4 (TCP/IPv4)” or “Internet Protocol Version 6 (TCP/IPv6)”. (TCP/IPv6)", depending on your network settings.
Click “Properties” and select “Use the following IP address”.
○ Enter the new IP address in the “IP Address” field.
○ Make sure the Subnet Mask and Default Gateway are set to the correct values.
○ Click OK, and then click OK again to close the properties.
3. Contact your Internet Service Provider (ISP):
○ Typically, home network IP addresses are dynamic and provided by the ISP. If you are still experiencing problems, you may need to contact your ISP for assistance.
4. Go to a public Wi-Fi network:
○ Connecting to a public Wi-Fi network sometimes provides you with a new IP address.
Please note that changing your IP address will not necessarily resolve your Internet or streaming issues with T-Mobile. If you are having problems with your Internet connection, it is best to contact T-Mobile or your ISP for further assistance.
