請問一下各位大大
我使用D-link的dir-1760 約三個月，
最近兩周，一直發生DNS解析錯誤，導致google, apple, FB 一類網站都連不上，目前的韌體是最新的1.02
也有試過把主dns 改成8.8.8.8，但是過了一陣子還是依樣會發生錯誤，無法上網，
只有把主機重開，重抓DNS，才能重新上網
請問該怎麼解決
謝謝

berlienlu 大大 您好：
請問您是申請哪一家電信? 想請問您是如何確認因DNS錯誤導致無法連線? 是有顯示錯誤訊息嗎?
1、無法開啟網頁時，請先確認登入DIR-1760設定頁面首頁下方，確認是否有顯示網際網路IP位址、主要DNS伺服器、輔助DNS伺服器。(如下圖所示)
2、確認無法連網的電腦區域連線中(TCP/IPv4)內容中，設定自動取得IP位址與自動取得DNS伺服器。
3、嘗試將DIR-1760回復至原廠預設值。重新設定設備一次看看。
硬體Reset步驟：在通電的情況下，拿迴紋針，按下Reset孔持續約10~12秒鐘後放掉即可。
若需要我們進一步協助歡迎私訊或致電D-Link技術諮詢專線。謝謝~

你好，我是中華電信，無法上網時，皆有抓到ＩＰ跟ＤＮＳ，
但如ＦＢ或google 網頁就是無法開啟跟搜尋...(恕刪)
berlienlu 大大 您好：
1. 請先確認中華電信數據機已關閉Wi-Fi分享的功能。
2. 嘗試於DIR-1760 基本設定>網際網路中，將MTU值改為：1445後儲存設定。並將數據機與分享器重開機一次。重開後再確認是否能開啟ＦＢ或google 網頁。謝謝~
