最近也裝了光世代
不過有一事很奇怪 就是只要閒置大概30分鐘左右 就會自動斷線 不知道各位有這情形嗎? 但是撥接程式並不會顯示已斷線 我是使用cfos撥接

我最近也申請了中華10M/2M,捉BT明顯比以前的ADSL 8M/648K快上許多!
剛剛進去看了一下ZyXEL的設定,感覺好像比其他人的還理想~

這樣的數值是否理想呢?!請個位大大幫我看一下嘍~感謝!!!

哀...寧願線路給MOD用，也不開給網路使用方面...

請問DELAY TIME的數據大家都是5.0居多
我怎是7.0呢??
Actual Delay: 7.0 ms 8.0 ms

97年9月裝的

Line Rate: 3.075 Mbps 14.102 Mbps－－－＞線路速度，可以不用看，只看Actual Net Data Rate就可以了
Actual Net Data Rate: 3.011 Mbps 14.014 Mbps　－－－＞線路實際傳送資料的速度
SNR Margin: 30.3 dB 30.8 dB－－－＞訊號雜訊比,個人覺得至少要10dB以上

大約解釋一下，希望大家看的懂

SNR Margin: 30.3 dB 30.8 dB－－－＞指的是抵抗雜訊的能力，基本上 6dB 就可以維持 Bit Error Rate 10^-6 了，當然越高訊號越好。
Actual INP: 18.0 symbols 18.0 symbols－－－＞Impulse Noise Protection，指的是對瞬間雜訊(如打雷)的抵抗能力，數字越高越好。18 symbols 代表要是有連續18個 損壞的 symbol 發生，它可以完全恢復。以 profile 17A 來說，約是 18 * 0.25 ms = 4.5 ms 的瞬斷。

請問怎樣登陸機子裡看這些資訊 要在哪邊做設定
我的是vdsl2
zyxel 的p-870h
型號是hgw-ve (p-870h-51)
因為我這邊很容易斷線（尤其是晚上和凌晨時候) 所以想知道是不是線路問題 還有用了光纖後
用電驢下載速度反而比先前用adsl的2m/256還要慢超多的 想知道是怎回事
我的isp是seednet的 感謝
