Hi  @lbuckley57,

May I know if your network topology diagram is as follows:

Cable modem—Archer AX73 )))((( client devices  or  Cable modem—Starlink router—Archer AX73 )))((( client devices

(Note: — stands for wired connection,)))((( stands for wireless connection )

Your ISP should have provided the following info and additional credentials for logins: PPPoE, Dynamic IP (SLAAC/DHCPv6), Pass-Through (Bridge), and Static IP.

Note: You may have received this information when your first signed up with your ISP. Otherwise, please get in contact with the support team from your ISP as they can provide the information.

Have you configured IPv6 for Archer AX73 according to the IPv6 configuration information of Starlink router?
Are there any error messages when using the IPv6 network of AX73? Please provide relevant screenshots.
