เป็นแบบนี้มานานแล้วครับ อาการคือ DSL หลุดบ่อยมากๆ ใช้เน็ตได้ครู่หนึ่ง DSL ดับเลย แล้วกะพริบไม่หยุด ต้องรอประมาณ 10 นาที ได้ใช้ แต่ก็ไม่เกิน 5 นาที หลุดอีก เสียอารมณ์มาก แม่บอกว่าจะยกเลิกเน็ตแล้ว ไม่ไหวหลุดบ่อยแบบนี้
ผมลองเช็คตัว DSL ได้มาแบบนี้ครับ

เท่าที่รู้คิอ Noise margin ผมต่ำมาก ผมควรทำยังไงดีครับ
