最近標了一台新的無線ATUR，家中使用環境為2M/256K，距機房3300公尺左右，2F兩台電腦，3F一台含ATUR，原有設備有642R51(bridge)、P312、BARSW4PHG、5PORT SWITCH，現在只用AWR-2440（pppoe）、5PORT SWITCH（無線功能關閉，使用原線路），使用上感覺3台電腦網頁開的比之前快，用NORTON線上掃瞄結果也與之前用P312時之結果一樣（設定都是預設），因為好奇拆開看了一下flash 4MB、SDRAM 16MB，無線模組好像是mini PCI介面，但是整台好熱喔，2天了還沒當機，上網查了一下規格如下供參考，

我也是用AWR-2440這台
請問要怎麼更新韌體阿
我把防火牆關掉就無法上網了～怪
要怎麼用阿

我的那台和你不一樣～我的規格是
