[SOLVED] Realtek_wifi.
* Realtek RTL8821AE firmware, version 29 (rtlwifi/rtl8821aefw_29.bin). Please see the snapshot attached. Also, you can see those files installed in my system:
/lib/modules/5.10.0-18-amd64/kernel/drivers/net/wireless/realtek/rtlwifi/rtl8821ae

However, wifi is no where to be found:

As part of journalctl list, you will see fail to load firmware: rtw88/rtw8821c_fw.bin. This file I downloaded from git hub, and it was not from realtek_20210315-3.deb from Debian 11 non-free packages.

Re: Realtek_wifi.
Does it work if you use the firmware from the repositories?
Note that you have an RTL8821CE, which is not the same as an RTL8821AE (the card you claimed to be using in your OP). The driver was only mainlined for kernel 5.9 so linux-image-amd64 from bullseye-backports might be better for that device. There are also some other driver versions available:

https://github.com/lwfinger/rtw88

Re: Realtek_wifi.
Thanks. Firmware: rtw88/rtw8821c_fw.bin is on lib/firmware/rtw88/rtw8821c_fw.bin. This one was clowned from lwfinger github. Do you know why it failed to load?Head_on_a_Stick wrote: ↑2022-09-23 23:02Does it work if you use the firmware from the repositories?

Re: Realtek_wifi.
No, I do not. There have been some reports in the past of buggy firmware releases, I found some links yesterday but I don't have them handy atm.
To be clear: remove the firmware you have downloaded manually and install the firmware-realtek package from the Debian repositories instead.

Re: Realtek_wifi.
Thank you very much for your time to work with me. However, Debian repositories doesn't support 8821ce as yet, only 8822ce. Only options now switching to Ubuntu 20.4, or staying with Debian and wait for new release from Debian's repository. I choose to wait instead.

Re: Realtek_wifi.
Are you on stable?
You can install the firmware from testing or sid, they are just firmware that don't depend on packages.

https://wiki.debian.org/InstallingDebia ... L8821CE%29This laptop has a Realtek RTL8821CE 802.11ac PCIe Wireless Network Adapter. It is not supported by bullseye's 5.10 kernel, but since 5.13 (I think).
I installed kernel 5.18 from bullseye-backports and now it's working. I haven't made any benchmarks, though.

Re: Realtek_wifi.
I forgot to mention that I still needed to install firmware-realtek_20210315-3_all.deb in order to work with kernel 5.18. How can I report this problem was solved?LTL wrote: ↑2022-10-05 19:39Thank you very much. It works.panpan wrote: ↑2022-10-04 10:21https://wiki.debian.org/InstallingDebia ...
