My network card doesn't work well in Ubuntu

Question

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.

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. — Logan, Mar 03 '23 at 19:50
Open a terminal and type inxi -N. Copy the output into your question (not the comments) — kanehekili, Mar 03 '23 at 20:04
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. — Organic Marble, Mar 03 '23 at 20:32
Does this answer your question? My wireless/WiFi connection does not work. What information is needed to diagnose the issue? — waltinator, Mar 03 '23 at 20:46
