ผมใช้เน็ตของ TOT 6M/512K แล้ววันนี้มีอาการหลุดบ่อยไม่ต่ำกว่า 5 ครั้งต่อวัน
จึงลองเช็คค่า Noise margin ดู

6 db น้อยมาก

ผมจึงทดลองดึงสายโทรศัพท์บ้านออกจาก Splitter


ลองเช็คค่าอีกครั้ง ปรากฏว่า

ค่า Noise margin เพิ่มขึ้น
และอินเตอร์เน็ตไม่หลุดเลย

พอเสียบสายโทรศัพท์กลับ อาการก็กลับมาเป็นเหมือนเดิม แต่อินเตอร์เน็ตไม่หลุดแล้ว

โทรศัพท์บ้านเป็นสาเหตุหลักหรือเปล่าครับ
