 |
|
| I just finished installing gentoo on my pc. During the installation of gentoo, my Comfast CF-723B WIFI usb adapter worked perfectly fine. However, now the internet wont work at all. I tried ifconfig -a to check on it, but the connection that I used during the installation no longer appea[/u]rs on the list. How do I get it to work? |

Darkstalker12,
Hi and welcome to Gentoo.
You're probably missing a kernel driver for your wifi adapter.
Please paste the output of lsusb. So we can get more info about your wifi adapter.

You have
| Code: |
Bus 001 Device 005: ID 0bda:b720 Realtek Semiconductor Corp. RTL8723BU 802.11b/g/n WLAN Adapter
|
If you google search the tuple "0bda:b720 cateee"
You get
https://cateee.net/lkddb/web-lkddb/RTL8XXXU.html
If you search additionally
you get
https://www.kernelconfig.io/config_rtl8xxxu
In this way you understand you need CONFIG_RTL8XXXU and where to find it in menuconfig(although you can search for config items from inside menuconfig by pressing "/").
You can do the same for pci devices by running
Do not forget to rebuild and reinstall kernel and modules.
Just remember to search by the id tuple and "cateee"

| I updated the kernel, and when I used ifconfig the device appered. However, when I try to start dhcpcd, all it says is "sending commands to dhcpcd process" and dosen't actually do anything. I tried to reboot it, but it still can't ping anything. |

| You should probably use something like wpa_supplicant to connect to your WiFi network. Does your WLAN adapter need firmware? You may need to install the linux-firmware package. |

Do you have any other working ifaces except the usb wifi?
Plz post
The easiest way to configure wifi connections is by installing
| Code: |
gnome-extra/nm-applet
|
This will of course pull NM.You will need to disable netifrc and dhcpcg etc and let NM handle connections.
Ethernet is easy.
wifi is a bit tricky.
You might also need
but i am not certain.Play around a bit.
https://www.kernelconfig.io/config_rtl8xxxu
+1 to @gentoo_ram for linux-firmware.

I'm trying to use wpa_supplicant, but when I try to use wpa_cli, all it says is
Could not connect to wpa_supplicant: (nil) - re-trying
I already tried messing around with /etc/wpa_supplicant/wpa_supplicant.conf[/code] |
