My network card doesn't work well in Ubuntu

fk flag

I have a little problem with my Asus F1400E, so basically when I try to install Ubuntu my network card doesn't work well, the connection is so unstable.

Im close to a router. I have installed W11 and with that OS doesn't have that problem. But i want to try Linux, I`m new to Ubuntu so if anyone could explain how to resolve the problem I would appreciate it very much. I try to install the solution that give this user of this forum. After this my connection was more stable but i can't get all the potential of my connection, so i left two captures of one connection test, one in Ubuntu and W11 to see the difference. 1

Network: Device-1: Realtek RTL8821CE 802.11ac PCIe Wireless Network Adapter driver:rtw_8821ce

The white one is from Linux and the black is from W11. I am im the exact same spot.

Sounds to me like a driver issue. The only thing that I can suggest is looking for the drivers specifically for that network card (probably Intel) from it's manufacturer's website. It may be hard to find the drivers for Linux.

Open a terminal and type `inxi -N`. Copy the output into your question (not the comments)

I have a 20.04 mini-pc that uses that device, and it works very well. https://i.imgur.com/YmTJx4C.png Download: 144.30 Mbit/s / Upload: 23.01 Mbit/s (speedtest-cli results) The only bad thing is that on this underpowered mini-pc it takes forever for DKMS to update the driver.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
