 Posted: Tue Jun 08, 2021 8:28 am Post subject: wlan0 Interface doesn't support scanning. |
 |
|
Hello, i am trying to set up a wireless internet connection but can't seem to do it.
i am following this guide: https://www.linux.com/training-tutorials/how-configure-wireless-any-linux-desktop/
when i run a scan i get this error:
| Code: | satellite ~ # iwlist wlan0 scan
wlan0 Interface doesn't support scanning.
|
I made sure to enable the drivers in the kernel; when i run ifconfig, the interface wlan0 is showing.
when i run lspci:
| Code: | satellite ~ # lspci | grep -i wifi
06:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)
|
Any help will be appriciated. |

Is it up?
| Code: |
ip link set wlan0 up
|
Try also
| Code: |
rfkill list
rfkill unblock <> |

the wlan was already up, since it was showing in ifconfig without "-a" argument, but i run the ip link set wlan0 up command just in case.
when i run rfkill:
| Code: | satellite ~ # rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
|
there is nothing to be unblocked[/b] |

Missing firmware?
Do you have
linux-firmware installed?
Also
| Code: |
CONFIG_RTL8192CE=m
CONFIG_RTLWIFI=m
CONFIG_RTLWIFI_PCI=m
CONFIG_RTLWIFI_USB=m
CONFIG_RTL8192C_COMMON=m
CONFIG_RTLBTCOEXIST=m
|
in your .config
?

i checked all these modules in kernel's .config and everything was already enabled (to m)
also firmware-linux was also installed, but i reinstalled it just in case |

i checked and everything was set as you said except these:
| Code: | # CONFIG_CFG80211_DEBUGFS is not set
# CONFIG_CFG80211_WEXT is not set
CONFIG_CFG80211_WEXT_EXPORT was not found
CONFIG_LIB80211 was not found and the rest if them
# CONFIG_MAC80211_MESH is not set
# CONFIG_MAC80211_DEBUGFS is not set
# CONFIG_APDS9802ALS is not set
# CONFIG_MAC80211_HWSIM is not set
|
should i enable them and then recompile the kernel? |
