The ISP's DHCP service is not working correctly, what should I do?

Question

Computer networks

Good afternoon, I decided to change the Internet. Everything works through the asus rt-n14u router. Directly to the computer everything works well, and through the router at first too. A day later, I began to give an error "the dhcp service of the Internet service provider is not working properly", although there are still no problems with the old Internet. Tried to turn it off for a while, does not help.

Answer 1

• Register static on the computer
  
• Or do a reset on the router
