的確,印象中之前用4M/1M時ping gateway也差不多是這個值。所以若不能用乙太網路供裝,就回應時間來說,能有的提升空間似乎有限。
不過以我現在的年資(電路費87上網費85)算下來,3M/768k的確是每個月便宜100左右。
在等待中午施工的同時,我把modem拆了下來,不經過防火牆,ping gateway的數據:
Ping statistics for 61.224.24.254:
Packets: Sent = 34, Received = 34, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 23ms, Maximum = 25ms, Average = 23ms
目前4031b內的連線數據,速率已經先改成4M/1M了,數字應該勉強還可以吧?
