我在一台新笔记本电脑上使用 Ubuntu 20.04.3 LTS。我的以太网连接似乎上限为 100MB/s，我想将其更改为 1000MB/s。我曾尝试使用以太网来做到这一点。这是我做任何事情之前 ethtools 的统计输出：

Settings for eno1:
    Supported ports: [ TP MII ]
    Supported link modes:   10baseT/Half 10baseT/Full 
                            100baseT/Half 100baseT/Full 
                            1000baseT/Full 
    Supported pause frame use: Symmetric Receive-only
    Supports auto-negotiation: Yes
    Supported FEC modes: Not reported
    Advertised link modes:  10baseT/Half 10baseT/Full 
                            100baseT/Half 100baseT/Full 
                            1000baseT/Full 
    Advertised pause frame use: Symmetric Receive-only
    Advertised auto-negotiation: Yes
    Advertised FEC modes: Not reported
    Link partner advertised link modes:  10baseT/Half 10baseT/Full 
                                         100baseT/Half 100baseT/Full 
    Link partner advertised pause frame use: Symmetric Receive-only
    Link partner advertised auto-negotiation: Yes
    Link partner advertised FEC modes: Not reported
    Speed: 100Mb/s
    Duplex: Full
    Port: Twisted Pair
    PHYAD: 0
    Transceiver: internal
    Auto-negotiation: on
    MDI-X: Unknown
    Supports Wake-on: pumbg
    Wake-on: d
    Link detected: yes

我尝试使用以下命令将速度设置为 1000，但是，我立即断开连接并且输出更改为未知：

user:~$ sudo ethtool -s eno1 speed 1000 duplex full
user:~$ sudo ethtool eno1
Settings for eno1:
    Supported ports: [ TP MII ]
    Supported link modes:   10baseT/Half 10baseT/Full 
                            100baseT/Half 100baseT/Full 
                            1000baseT/Full 
    Supported pause frame use: Symmetric Receive-only
    Supports auto-negotiation: Yes
    Supported FEC modes: Not reported
    Advertised link modes:  1000baseT/Full 
    Advertised pause frame use: Symmetric Receive-only
    Advertised auto-negotiation: Yes
    Advertised FEC modes: Not reported
    Speed: Unknown!
    Duplex: Unknown! (255)
    Port: Twisted Pair
    PHYAD: 0
    Transceiver: internal
    Auto-negotiation: on
    MDI-X: Unknown
    Supports Wake-on: pumbg
    Wake-on: d
    Link detected: no

我假设这是由于在将速度设置为 1000 之前“链接合作伙伴宣传的链接模式”不包括 1000baseT/Full。但是，我的互联网提供商发誓这不是他们的路由器。在我的旧公寓和我的旧电脑中，以太网电缆很容易处理 1000MBit/s。

有人知道这里可能出了什么问题吗？
