我有一台装有 Ubuntu 20.04 和 Windows 10 的双启动笔记本电脑 Asus Zenbook Pro 15。我检查过,当我使用装有 Windows 的电脑时,我的无线连接速度比使用 Ubuntu 时更快,信号也更强。

从上面的输出来看,我正在使用iwlwifi
驱动程序。有人知道如果我使用不同的驱动程序是否可以改善我的 WiFi 连接吗?如果不是这样,是否有任何配置可以尝试来修复它?

答案1
您所连接的 SSID 是:
MiFibra-1B0A_EXT 基础设施 100 135 Mbit/s 50 ▂▄__ WPA2
如果您有路由器的管理权限,请检查其设置。首选 WPA2-AES;而不是任何 WPA 和 WPA2 混合模式,当然也不是 TKIP。
我建议使用固定频道,而不是自动频道选择。我注意到,在您的阅读中,还有其他几个 5 gHz SSID,并且至少有两个也在频道 100 上。我建议您选择一个远离附近其他频道的频道。
您可以使用终端命令查看无线设备支持的频道:
iwlist freq
然后比较路由器中可用的通道,并选择读数以外的通道。
接下来,我们的无线网卡可能会因为电源管理而掉线或变慢;电源管理是指在非活动期间,卡会部分断电以节省电池电量,然后在活动恢复时无缝地重新通电的功能。让我们禁用省电功能,看看是否有帮助。从终端:
sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/*
在路由器上进行更改后,通过电源循环重新启动它。
