ช่วยด้วย Zyxel P660HW-T1 V2 noise ต่ำ

[OVERMAN]

สงสัยครับ ทำไม noise margin ที่ได้จาก Zyxel P660HW-T1 V2 ตัวนี้มันต่ำจังครับ

เมื่อก่อน ใช้ Bipac 7000+ ได้ประมาณ 33
ใช้ P660R-T1 ก็ได้ประมาณ 33 พอกัน
แต่ใช้ T1 V2 ตัวนี้ อยู่ที่ประมาณ 17-21 แค่นั้นเอง ทั้งที่เบอร์เดียวกัน สายเดียวกัน งง ครับ

เป็นที่อะไรครับ แล้วจะแก้ยังไงได้

[OVERMAN]

เยอะกว่าผมอีกอะของผมพอต่อลงชั้น 2 ดอบจาก 34 เหลือ 14 เลย SNR
ของคงอาจจะที่ Adsl Mode ป้าว

แก้ไขได้หรือยังครับ

[kidnapped1]

ลอง Adsl mode g.dmt ดูอาจจะดีขึ้นไม่ต้องกลัวครับ รีแล้วมันรับค่าเดิมไม่หมดประกัน (True นะ)

Start > Run > cmd > telnet 192.168.1.1 กด Enter

ใส่รหัสของตัว Router

แล้วพิมพ์ว่า
wan adsl opencmd gdmt
กด Enter
wan adsl reset
กด Enter

ไม่รู้ maxnet มาเจอ 660hw Adsl mode g.dmt จับสัญญารไม่ได้เลย งง เหมือนกกัน

[OVERMAN]

ก็ยังไม่ได้ดีกว่าเดิมครับ

ลองปิดบิทดูนะครับ รุ่นนี้มีปัญหา NAT MAX เต็ม ถ้าปิดแล้วเข้าเวปได้ปกติ ลองเข้าไปปรับหน้า nat จาก 512 เป็น 1024 ดูจะดีขึ้น ไม่ก็เปลี่ยน uTorrent เลยผมหายเลย

ปรับแล้วครับ แล้วก็ใช้ uTorrent ตามปกติ แต่คงต้องรอดูผลซักระยะก่อนนะครับ

วงจรในเราเตอร์ มันไปกวนสัญญาณครับ
ถอดตัวบนออกแล้วหาย เป็นเรื่องปกติ(ถึงจะไมไ่ด้เปิดใช้ก็เหอะ)

ถ้าใช้G.dmt ไม่ได้ ลองใช้คำสั่งเป็น T1.413ดู
ในZyxel อาจจะต้องพิมพ์เป็น T1413

สายมันยาวเกินป่าวครับ มันอาจจะยาวมาก และไปผ่านอุปกรณ์อะไรเข้า เกิดการรบกวน

สายสั้นก็เป็นครับ

แ้ก้ NAT เป็น 1024 แล้ว ลองใช้มาหลายวัน คิดว่าอาการน่าจะหายแล้วครับ

ขอบคุณครับ
