大家好, 我自上週12強美國打委內瑞拉那一天晚上開始, 就發現家裡的網路出現異常(慢) , 這幾天已嘗試路由器重置, 但不有效, 所以上來和大家詢問, 我會盡量提供完整資訊給大家, 謝謝！老實說我剛開始以為, 是12強的關係, 大家都在看網路直播, 所以網路比較慢, 但是台灣都打完得冠軍了, 我網路反兒更慢, 這幾天還出現無法上網的狀況, 打開銀行APP會顯示失敗那種, 我的資訊如下: 1. 路由器: 陸版小米路由器 AX3000 Mesh 黑色/ 2022 年購入 2. 網路線: 綠聯 CAT6A (家裡全部都是 CAT6A 2022年更新) 3. 固網商: 大大_頻 (100Mbps/100Mbps) 4. 全家都是 WIFI6, 有2.4g頻段和5g頻段, 雙頻合一, 給設備自行選擇 5. 家裏的 wifi 如下 https://imgur.com/ZsSITzI

5. 已嘗試 (1) (X)網路被偷聯 -> 已改密碼, 但是網路慢, 甚至打不開 (2) (O)重置路由器 -> 已重置2、3次, 但是網路慢, 甚至打不開 (3) (O)更改頻段 -> 已更改, 但是網路慢, 甚至打不開 https://imgur.com/bSjoqzr

(4) (O)找尋錯誤報告: 這部分比較有意思, 原來小米路由器有後台管理頁面, 一打開就發現大大的錯誤訊息, 如下圖所示, 前面幾個我看不懂, 不過DNS解析異常我還知道, 我有試手動改DNS 為 8.8.8.8 和 1.1.1 .1 結果更「慘」, ping 飆到20000多, 如下 https://imgur.com/PmqKdlE

不能改 anyware 至少我去兩年多用的很正常啊, 6. 補上測速報告, 網路連得上時狀況, 連不上就根本打不開 https://imgur.com/jEifaVF

7. 電腦中毒？家裏都是 mac , 已掃毒顯示正常希望大家幫我解答看看, 或是要任何資訊我都可以再補上, 我同時也有預算可以買新路由, 如果能解決問題當然沒問題謝謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 118.150.0.10 (臺灣) ※ 文章網址: https://www.ptt.cc/bbs/Network/M.1733144860.A.441.html ※ 編輯: raindeer896 (118.150.0.10 臺灣), 12/02/2024 21:11:52 ※ 編輯: raindeer896 (118.150.0.10 臺灣), 12/02/2024 21:13:03 ※ 編輯: raindeer896 (118.150.0.10 臺灣), 12/02/2024 21:15:32
