 Posted: Mon Aug 14, 2017 2:49 am Post subject: No Wireless Interface / No idea why |
 |
|
First time playing around with Gentoo. Really enjoying it so far, but getting my RTL8188CE wireless interface to show itself is driving me insane. I believe Ive enabled the right fields in genkernel's menuconfig, systemlinked net.wlp7s0 to net.lo, emerged linux-firmware. Its been two days and no hope.
Recently found this giys blog and enabled all Realtek's family as modules, but nothing.

CONFIG_RTL8192CE should be the kernel option to enable for that card. Just throwing it out there, but I bought one to use as an AP and it lasted all of 5 minutes. The module still loads and unloads fine and I can change channels and SSID name, but none of my wireless devices detect it. Maybe I just got a bum card.  |

The information you gave from lspci are missing important information. Please add the -n and -k options: | Code: | | lspci -nnkv | sed -n '/Network/,/^$/p' |
And as described in the Wifi wiki article, you could boil down the dmesg output to the relevant lines. |

Hi!,
Don't forget to emerge linux-firmware too.
If it still doesn't work, I could give you my wpa_supplicant.conf details, because the default -wext doesn't work, you need to define an other driver, bu I forgot its name.

Bunter, I just checked my kernel config, and thats set to be loaded as a module. Do tou mean I should pass it as an arg from grub at boot? Im wondering if genkernel is doing what I ask of it - I bet it is, humans are usually the issue when it comes to things like this.

Linux-firmware is emerged, and in /etc/genkernel set:
| Code: | FIRMWARE="yes"
FIRMWARE_DIR="/lib/firmware" |
xaviermiller, so something other than RTL8192CE is needed?
Thanks for the help. |

genstoopid,
What is the date/time in
Its the date/time that the running kernel was compiled. Does it look right or has the kernel update gone wrong somewhere?
Not mounting /boot before installing the new kernel is popular.

Yeah the new kernel is being used, and its the stable amd64 version - 4.9.34.
NeddySeagoon, /boot is mounted.
Why is it always wifi? ><

genstoopid,
What does | Code: | | zgrep RTL8192CE /proc/config.gz |
return?
Does /proc/config.gz exist ?

Y tho?
Edit: Im manually building the kernel now with make (hope Im able to boot into my LUKS rootfs) , we'll see if that helps tomorrow. A friendly desktop's distcc is chugging away at it, but it's still going to be 2 hours from now. |

genstoopid,
That's from your running kernel, which may not be the kernel you just built.

| Yeah, I'm at a loss. I just ran genkernel again with --no-oldconfig (even though OLDCONFIG="no" in genkernel.conf) and verbose=2 and it seems to still be pulling silentoldconfig. Could that be the issue? |

genstoopid,
I've never used genkernel. Run it with the --menuconfig option and check the settning before you let it build.
You can change the settings there too.

Hi!
Once you will have done with kernel configuration, if wpa_supplicant still cannot be started, try to change the default driver (wext) to (nl80811), in /etc/conf.d/wpa_supplicant | Code: | # conf.d file for wpa_supplicant
#
# Please check man 8 wpa_supplicant for more information about the options
# wpa_supplicant accepts.
#
wpa_supplicant_args="-Dnl80811" |
But do that only if the error message is that you cannot associate, and that the module is well loaded, with the firmware.

I'm an idiot. I had to be a special snowflake and rename my .config something else, and of course I didnt set --config when calling genkernel. I hate myself for wasting everybodys time.
If anybody finds their way to this thread googling their problem: save your config as .config
Will donate 5 clams to gentoo. 
Edit: xaviermiller thanks for the tip! Im sure that'll be my next problem =p Right now Im trying to wrangle booting into LUKS. Seems like Im missing something (always). |

Don't be too hard on yourself. Unless you repeat the mistake :)
