關於有線網路 v.3 By 國青網管

＊本文件為Windows XP、Vista和windows7、windows8、windows10的使用者編寫。

＊歡迎使用台大宿舍網路，使用100Mbps高速的區域網路連線是您的權利，維護自己電腦
的安全與尊重智慧財產權則是您的義務。請不定時更新病毒碼，windows update，使用反
間諜軟體(SpyBot, Ad-Aware SE, Spyware Terminator, Advanced Windows Care)掃瞄您
的電腦。為了維護其他使用者的權利，若您的電腦被偵測出中毒或有不法的行為，您的網
路將會被暫停使用。

＊您的計中帳號(學號)必須啟用、住宿服務組的資料必須在國青、電腦的網卡也沒有在
其他宿舍註冊過，您才可以在國青宿舍內使用有線網路。以下為註冊您網卡的方式，若過
程中出現「無法顯示網頁」，請把「區域連線」停用再啟用，無法解決問題就重開機試試
看。

Step 1 開始→控制台→1.網路連線(Windows XP)
→2.網路和網際網路(Vista和windows7)
→網路和共用中心(Vista和windows7)
3.在「有線網路圖示」上按右鍵→開啟網路和共用中心(windows8、windows10)
Step 2 1.在「區域連線」上面按右鍵，選擇「內容」(Windows XP、Vista、windows7)
2.點選「乙太網路」，選擇「內容」(windows8、windows10)
Step 3 在一般分頁裡，點選Internet Protocol (TCP/IP)，然後按「內容」
Step 4 在「一般」分頁裡面，選擇「自動取得IP位址」與「自動使用DNS伺服器位址」
Step 5 打開瀏覽器，點「請點選此處以進行宿舍網路註冊」
若沒出現註冊頁面請輸入網址 https://140.112.2.197/register_dorm/
Step 6 若出現憑證過期的對話視窗，請按OK讓註冊過程繼續
Step 7 出現「宿舍網路註冊系統」，請輸入您的計中帳號密碼登入
Step 8 請確認您的個人資料是否無誤，沒有錯的話就按「資料確定」
Step 9 系統會自動取得您的MAC 位址
Step 10 請把得到的IP位址抄起來
Step 11 重複 Step 1至Step 3
Step 12 如果可以上網了就到這邊結束。如果不行，
在「一般」分頁裡面，填入剛剛得到的IP位址。
子網路遮罩設255.255.255.0，預設閘道則設140.112.XXX.254。
(XXX為Step 10所得IP的140.112.XXX.YYY)
DNS建議您填以下四個伺服器：140.112.2.197, 140.112.254.4、
140.112.2.2、140.112.18.1。
Step 13 等候五到十分鐘就可以上網了，祝上網愉快*^^*


＊若您的室友是外籍生又看不懂中文，請協助他們註冊網卡，謝謝您！

＊查詢網卡MAC位址：執行C:\WINDOWS\system32\cmd.exe，在對話視窗內輸入
ipconfig/all，找Ethernet adapter 區域連線的Physical Address。

＊台大宿舍網路系統不允許兩個相同的MAC位址，若您之前住在台大的其他宿舍，請確定
舊宿舍的網管已經將您的MAC位址刪除。

＊查詢本機連線狀態：「開始」→「執行」→輸入「cmd」確定，在對話視窗內輸入
netstat -n，就可以看到目前電腦的所有連線。

＊每個IP每天的流量(上傳+下載)限制為bGB，若您超過這個限制，您的IP當天會被限速
，每天晚上十二點流量重新恢復6GB，重新計算。

＊若您使用p2p軟體侵犯智慧財產權而被外面的公司追蹤到，您可能會收到一封來自計中
的公文。這封公文也會寄給住宿服務組、宿舍教官、以及您就讀的系所，請三思。

＊若遇施工或停電必須斷線，恢復網路的時間有時很難掌握。若已經過了公告的預計恢
復連線時間卻還沒辦法上網，請耐心等候。若遇校內其他單位網路施工，即使國青不在施
工範圍內，仍有可能出現網路斷斷續續的情形。
＊若您使用Outlook收信，請把郵件預覽的功能關掉，以避免電腦中毒。

＊簡易FAQ：
無法註冊網卡 請聯絡網管或至一樓填寫維修單

忽然沒辦法上網
先嘗試重新開機，有時候可能是作業系統出現問題。
也請嘗試將作業系統更新到最新版本。

嘗試其他瀏覽器如 Firefox、Google Chrome，
看看是否Internet Explorer 出現問題。

把網路線拔掉再重插，如果問題持續，再嘗試重新安裝網路卡驅動程式。

改用室友的網路孔試試看。

檢查IP、DNS、閘道、子網路遮罩等設定是否有錯誤。台大的IP都是140.112
開頭，預設閘道為140.112.XXX.254(見 step 12)，子網路遮罩為255.255.255.0，
DNS請填step 12建議的那4個。

換了新電腦或安裝新的網路卡，請自行更改MAC位址。
或是您在宿舍系統裡的資料不見了，請登入以下網頁檢查。
連上 https://140.112.2.197 選宿舍網路註冊系統

如果您的IP可能被鎖起來了，請至台大資通安全小組網頁
http://cert.ntu.edu.tw/ip.php 依日期或IP查詢

停電或施工過後，有時hub會出問題，請聯絡網管
速度突然變很慢 也許您當天流量已經超過6GB的限制而被限速
