순간적인 끊김 현상

CPU - INTEL 콘로 L-430 M/B - ASROCK CONROE 133-D667 RAM - 2G 무선공유기 ipTIME G104BE 무선랜카드 ipTIME G054P 유선 연결된 컴 윈도우 XP 사용 - 특별한 문제 없음 무선 연결된 컴 윈도우 2000, 윈도우 XP 두개 사용중 윈도우2000에선 온라인 게임을 할때 특별히 인테넷이 느리거나 끊기는 느낌은 들지 않았는데 XP에서 게임을 하면 순간 순간 끊기는 느낌이 들어서 ping 테스트를 해보니 유선 연결 컴 윈 XP와 무선 연결 컴 윈도우2000 에서는 ping값이 10ms-14ms 사이로 일정한 값을 유지하는데 무선 연결된 윈도우XP에선 순간적으로 ping값이 1000ms로 종종 뛰어버림 Pinging yahoo.co.kr

Ping statistics for 119.161.11.206:     Packets: Sent = 80, Received = 80, Lost = 0 (0% loss), Approximate round trip times in milli-seconds:     Minimum = 13ms, Maximum = 1865ms, Average = 36ms 위의 결과 처럼 몇초마다 한번씩 ping time 수치가 1000을 넘어버림 인테넷 웹써핑하는데는 별다른 불편한 점은 없지만 온라인 게임할때 몇초마다 순간적으로 게임상의 캐릭터가 정지하고 1-3초간 무방비 상태로 공격만 받는 상태가됩니다. 일반적인 무선 랜카드 특성상 문제라면 그냥 넘어가겠지만 윈도우2000에서는 특별히 문제가 없었는데 왜 윈XP에서만 이런 현상이 일어나는지?
