与同一个网络中的智能手机和其他笔记本电脑相比,上传/广播的速度非常慢

我确实想将视频投射到我的Google Chromecast,但是我面临的连接速度非常慢,这在同一网络中的其他设备上是不会发生的。 例如,我正尝试从Plex发送内容,但它没有启动或确实经常出现打but,但是如果我导航并从智能手机或另一台笔记本电脑中选择相同的文件并进行投射,则它的工作原理就像一种魅力。

我说的是投放,因为我以前没有遇到过慢的互联网连接,只是因为我的互联网提供商本身提供的上传速度真的很慢,而且我没有以其他方式注意到它。

I'm on Ubuntu 20.04 but I also had this problem on older versions. I tried to add options iwlwifi 11n_disable=2 (but also 1 and 8) in /etc/modprobe.d/iwlwifi.conf without results. I also tried to disable the iwconfig power management with sudo iwconfig wlp2s0 power off and to turn off the TLP power saving stuff, but nothing helps. Please send help, I'm going mad. ?

iwconfig result:
