Kể từ khi tôi cài đặt 12.04 (cài đặt sạch không phải là nâng cấp), tôi đã bị giảm kết nối Internet. Sự sụt giảm trong kết nối có thể là bất cứ điều gì từ 15 giây đến khoảng 3 phút và sau đó kết nối trở lại. Hành vi này xảy ra trong khi tôi đang tích cực duyệt Internet hoặc nếu tôi đánh thức máy tính và mở Firefox (đôi khi tôi có kết nối và đôi khi tôi không có). Xin lưu ý rằng khi kết nối Internet được bật, nó không bị chậm (như kết quả speedtest.net hiển thị).
Ban đầu, tôi nghĩ đó là vấn đề với trình điều khiển r8169 cho thẻ Ethernet RTL8111 / 8168B của tôi, vì vậy tôi đã tải xuống r8168 từ trang web Realtek, làm theo hướng dẫn chi tiết (danh sách đen r8169, thay đổi tệp thành .bsh
...), nhưng vẫn Vấn đề tương tự vẫn tồn tại.
Vì vậy, tôi đã chuyển sang kết nối không dây và tôi gặp vấn đề tương tự với kết nối Internet bị rớt ngẫu nhiên.
Có ý kiến gì không? Cảm ơn trước.

Lưu ý rằng thẻ không dây của tôi không hiển thị, tôi có thẻ Ralink 3390 (dường như không hiển thị trên Ubuntu vì một số lý do), tuy nhiên tôi có thể kết nối với mạng không dây và kết nối với Internet (khi nó hoạt động).
ifconfig

có thể giúp ích rất nhiều. Nếu bạn không thay đổi gì khác về hệ thống của bạn; không phải là vị trí trong nhà hoặc doanh nghiệp của bạn hoặc bất kỳ phần cứng nào, cũng không phải bất cứ điều gì về mạng của bạn, sau đó tôi nghĩ vấn đề của bạn là <em> KHÔNG </ em> hệ thống của bạn. Vì vậy
