我刚搬进新家,一直在设置互联网,但似乎我的台式机不喜欢新的互联网环境。最初,我测试了一下是否是我设置的 Ubiquiti 设备,但其他所有设备无论hardwired device was getting the expected 500-600 Mbps whereas the desktop was getting somewhere between 140-180 Mbps.
我将连接直接插入调制解调器、USG-3P(路由器)还是 US-16-150W(交换机),此结果在设备之间保持一致。有问题的台式机使用 Realtek GBE 系列控制器,在 UniFi 控制器和原生 Windows 10 网络适配器属性上均确认有 1.0 Gbps LAN 连接。
桌面操作系统:Windows 10 Pro
笔记本电脑操作系统:Windows 10 家庭版
这是我迄今为止尝试过的:
ipconfig /flushdns
同时使用 ISP 和 Google DNS
启用/禁用 QoS 数据包调度程序服务
通过 Realtek 网站更新 Realtek 驱动程序
使用 MSI Live Update 更新驱动程序
顺便说一句,这台台式机的上行速度实际上是预期的量(25Mbps),这让我更加困惑。到目前为止,我的谷歌搜索失败了。有什么故障排除方法吗?
更新 1: 带网络连接的安全模式也给我带来了同样的结果,下行速度约为 140-160 Mbps。
更新 2: 我还没有对 Linux LiveUSB 进行过测试,但我已经按照下面的建议购买了基于英特尔的芯片组,并得到了一些有趣的结果。此测试是在同一台笔记本电脑和台式机之间进行的。台式机运行的是 Windows 10 Pro,笔记本电脑运行的是 Windows 10 Home。
iperf3 结果如下:
在新的英特尔适配器(带有英特尔芯片组 82546 双端口千兆 8492MT NIC 的 Jeirdus)上:

尽管旧适配器上的 LAN 吞吐量似乎更高,但英特尔适配器似乎更接近台式机上的 WAN 下行吞吐量。也许 Realtek 适配器的吞吐量是错误的?无论如何,如果有人有进一步的故障排除步骤来恢复此特定台式机的 WAN 速度,我将不胜感激。
答案1
事实证明我并没有尝试使用以下命令来重置适配器:
netsh winsock reset
netsh int tcp reset
netsh int ip reset
此后重新启动解决了我的问题。
