我在那里,所以我应该可以收到200Mbps
互联网连接速度,但我只能95 Mbps
在 www.speedtest.net 上获取。所以我检查了我的eth0
接口,它似乎支持千兆连接,我的以太网电缆是cat5
。
当我跑步时sudo ethtool eth0
Settings for eth0:

“链接伙伴”是您的计算机所连接的交换机/路由器/调制解调器。上述诊断的可能解释:
- 链接伙伴不支持千兆以太网(或者由于某种原因已被禁用,例如为了节省电力)。
- 连接电缆的信噪比太低,因为它们缺乏适当的电磁屏蔽。这可能导致链接伙伴同意降低链接速度以保持可靠的连接。如果是这种情况,请将电缆(以及任何其他潜在的连接设备,如墙上插头)更换为至少具有 CAT5e 或 CAT6 屏蔽且未损坏的电缆。
