@Jasondidit,

If I am reading this correctly, you disabled the bridge mode on your router after contacting your ISP?

If so, the only way to get rid of this is to either potentially disable the DHCP and addressing functionality on your ISP router, or connect your TP-Link router as an access point. This would still allow you to take advantage of the improved network hardware from TP-Link, but would remove many of the management features that come with the router, as the device from your ISP would then be in charge of managing your entire network.
