Without having further information, it's difficult to determine if the problem might be with the Blu-ray player, the connection, or the router. Unfortunately I don't have any way to assist on this.
If you'd like to attend troubleshooting, we offer live chat on the Samsung.com support page. If it's not the player, and instead it's an issue with the router or the Internet connection, you may need to contact the customer support for those products. Here's the link to Samsung's assistance:
