You can increase the DHCP Server Lease Time which is shown in the picture , but generally the IP address renewal when the DHCP lease is up should be pretty much transparent . Try checking the ' Auto reserve IP for the same host ' as well , that should make the router give your PC the same IP address as the last time whenever the DHCP lease is up this might be why your connection seems to drop as the router will probably give you a different address and thus break the existing connections . Edit I would first try just checking the option , and then , if the IP renewal still causes issues , I would increase the lease time as a workaround . Bear in mind though , that if you make it too large say 100 days , not sure what the max value is , you might run into an issue when new devices won ' t connect to the network , because you have exhausted the IP pool . This depends on the router , some will release the oldest leases when they run out of IPs , but some won ' t give out any IP until some of the leases expire on their own .
