前些日子,發現我連線下載只有 110 k byte/ sec 左右,連絡客服人員,做了一些測試,隔天有請中華來看,他檢查了一下線路,後來說正常,幫我把 數據機從
Tecom 1086-B 換成 Tecom 4031C ,我有觀查數據機內的數值,發現有時候 ( 某些時段 ),數據機內下載數值不到 2048 Kbits/sec ,之前最低只到 1100 Kbits/sec ,換了數據機最低還 是只有1504 Kbits/sec , 可是常常在一些時段是正常的,因為請中華電信來,也不一定當下會有問題。有人有遇到過嗎?該如何解決。


以下是數據機內的數值

SNR值已經低於一般正常值...
這個可能需要請人看一下室內室外線...
看起來雜訊很高??
