我的 Ubuntu 20.04 网速非常慢

嗨,几个月前我买了一台新的戴尔 Inspriron 5501。从来没有真正用过它。但是安装 Ubuntu 20.04 后,我的互联网仍然很慢。我的下载速度只有 100KB/秒,而当我尝试使用 google speedtest 时,它应该是 6-10MB/秒(大约 100Mb/s 的速度)。它显示下载速度为 0.5Kb/秒,上传速度为 22-30 Mb/s。如果我有相同的下载速度,那就足够了。我整天都在使用笔记本电脑,我进行了所有更新和升级,并查看了所有文章和视频,但没有任何帮助。我正在用手机写这篇文章,因此对于我应该包含的任何信息,请在评论中告诉我。
