Hello,

I installed Gentoo a few days ago. Everything went fine, it worked like a charm for two days and then today I can't connect to the local network. It turns out that dmesg prints:

Quote:
rtl8192ce_firmware_selfreset() 8051 reset failed


and then it starts polluting the output with tons of messages like "MAC reset failed". I tried to bring the iface down, doesn't work. Tried to reboot, doesn't work. I changed nothing sensitive these two days, just spent some time setting make.conf variables, installing packages and choosing stuff with eselect.

The device itself is working fine, windows recognizes it with no warnings/errors and no problems connecting to the network.

Seems to be a wlan chip.
You may reconfigure wlan and check if you have enabled verbosity in kernel.
You may also provide the needed firmware for this chip. Sometimes it has to be from google, sometimes linux-firmware, it is everytime different... sometimes just reconfiguring the kernel.

Code:
[I] sys-kernel/linux-firmware

do you have that package installed?

Completly irrelevant, as windows drivers, fixes bios bugs, gpu bugs and other stuff. e.g. my nvidia gpu has some bios / gpu bios bugs ...
do not expect that any bios / firmware / other stuff is production ready when hardware is sold. most often the windows drivers just fixes in the field the hardware to the desired behaviour. most reason why we have flash chips, so we can flash bios / gpu bios / flash firmware of SSD / ... lol
Only releveant is when any other linux distro works, than you can copy over the settings from that distro to gentoo.

Sorry, I should have mentioned it.

Yeah, irrelevant per se, but I meant the device was tested for not being physically broken.

I'm not definitely sure, but I guess that fixed the problem.
I totally forgot to look for the firmware package. Thanks!!
