핸드폰에서 wifi 로 특정 앱만 들어가면 공유기가 죽는 현상이 발생하여...

신기해 함과 동시에 머리가 아프네요 ㅜㅜ 
해결책이 있을까 질문드립니다. 

문제의 앱은  골프 삼성 앱(안드로이드)입니다. 

공유기는 RT-AC68U merlin 펌웨어 (버전 386.3)사용중입니다.

문제를 조금더 자세히 설명하자면 .

골프삼성이라는 앱을 깔고 집의 와이파이 연결 상태에서 실행을 시키면 

웹페이지를 사용할 수 없다는 에러메시지가 뜹니다. (캡쳐그림 참조)

그리고는 핸드폰의 wifi가 죽고.

동시에 공유기가 죽습니다. 전원이 나가진 않습니다.(모든 표시등은 정상임) 

wifi 연결뿐 아니라 유선연결안되는 것으로 보아 

warm booting 인듯 합니다. 

로그를 볼때  그런 것 같습니다. (하단 로그 참조)

두대의 핸드폰 모두 같은 앱에서 동일한 현상이 일어납니다.(다른 앱에서는 이런 현상이 없었음).

몇번의 반복실험에서도 동일한 현상이 나타나네요....

특정 앱이 특정 사이트 들어갈려고 할때마다 공유기가 죽는다는 현상은 듣도보도 못한 일이라...당황스럽네요.

1. 있을 수 있는 일인가요?

2. 어떻게 대응해야 하는 걸까요 ? 

SK broadband 사용하고 있습니다. 

문제의 앱은 골프삼성이라고 하는 골프부킹하는 앱입니다. 

도와주세요..
