 Posted: Thu Dec 21, 2023 11:25 am Post subject: USB WLAN adapter (TL-WN725N) not detected by NetworkManager |
 |
|
I have a USB WLAN adapter (TL-WN725N) that used to work fine before. It is listed pretty much everywhere and so is the Wi-Fi interface, except with NetworkManager. I cannot enable Wi-Fi via nm-applet right click context menu.
On Arch Linux (installed on the same machine, on another SSD, I can enable Wi-Fi from nm-applet just fine and connect to any network.
| Code: | $ lsusb
Bus 003 Device 004: ID 0bda:8179 Realtek Semiconductor Corp. RTL8188EUS 802.11n Wireless Network Adapter |
| Code: | $ ip addr

link/ether c4:6e:1f:1f:c0:2b brd ff:ff:ff:ff:ff:ff |
The interface (wlp0s20u11) isn't listed when running $ ifconfig.
However, it is after enabling it manually:
| Code: | # ifconfig -v wlp0s20u11 up
$ echo $?
0 |
| Code: | $ ifconfig
wlp0s20u11: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500

The interface (wlp0s20u11) isn't listed with both $ nmcli device status and $ nmcli device status
I'm using sys-kernel/gentoo-sources. Tried with 6.1.67, 6.6.8, 5.15.42, same behavior.
As I said, it used to work before and I don't think I changed anything Wi-Fi related in my kernel config. My two Ethernet interfaces are working just fine with NetworkManager.
Wi-Fi is enabled as per Gentoo Wiki - Wi-Fi - Kernel:

Realtek RTL8188EU Wireless LAN NIC driver is also enabled:
| Code: | Realtek RTL8188EU Wireless LAN NIC driver
CONFIG_R8188EU:
This option adds support for the Realtek RTL8188EU chipset, used in USB
devices such as the ASUS USB-N10 Nano. This newer driver is based on GitHub
sources for version v4.1.4_6773.20130222, and contains modifications for
newer kernel features. If built as a module, it will be called r8188eu.

I also tried with net-misc/networkmanager-1.44.2 + gnome-extra/nm-applet-1.34.0 (testing) followed by a reboot, but it doesn't make any difference.

| Also try the replacement driver rtl8xxxu in kernel 6.5 or higher as the old staging driver has been removed. |

eeckwrk99,
You don't mention linux-firmware. Almost all USB Wifi needs that.
What does dmesg show, that's a pastebin ?
-- edit --
| Code: | $ qlist -U wpa_supplicant
net-wireless/wpa_supplicant dbus fils hs2-0 mbo mesh readline |
Do you have an old insecure WiFi system that needs USE=tkip there?

Thank you, it's now working as expected with 6.6.8 after enabling this:
| Code: |
Symbol: RTL8XXXU [=m]
Type : tristate
Defined at drivers/net/wireless/realtek/rtl8xxxu/Kconfig
Prompt: Realtek 802.11n USB wireless chips
Depends on: NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_REALTEK [=y] && MAC80211 [=m] && USB [=y] && LEDS_CLASS [=y]
Location:

-> Wireless LAN (WLAN [=y])
-> Realtek devices (WLAN_VENDOR_REALTEK [=y])
-> Realtek 802.11n USB wireless chips support (RTL8XXXU [=m]) |
However, as you point out, this option doesn't seem to exist with 6.1. The closest is:
| Code: | Symbol: RTL8XXXU [=n]
Type : tristate
Defined at drivers/net/wireless/realtek/rtl8xxxu/Kconfig:5
Prompt: RTL8723AU/RTL8188[CR]U/RTL819[12]CU (mac80211) support
Depends on: NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_REALTEK [=y] && MAC80211 [=m] && USB [=y]
Location:
-> Device Drivers
-> Network device support (NETDEVICES [=y])
-> Wireless LAN (WLAN [=y])
-> Realtek devices (WLAN_VENDOR_REALTEK [=y])
-> RTL8723AU/RTL8188[CR]U/RTL819[12]CU (mac80211) support (RTL8XXXU [=m]) |
I didn't bother trying it before considering "RTL8188[CR]U" (not "[E]"U). I've just tried it just to make sure, unfortunately it doesn't change anything.

This is the same version than on my Arch install (where the adapter works with 6.6 and 6.1 kernels).

No, I'm using WPA2-AES.
dmesg doesn't print anything interesting on 6.1.67:
| Code: | [ 1.926909] usb 3-11: new high-speed USB device number 4 using xhci_hcd

I cannot remember if I ever got it working on any 6.1 kernel. I use it very rarely. Maybe it's not supposed to work with 6.1 at all? |

The staging drivers for wireless exist there because they are not up to modern standards and may (not) work as other drivers do.
Recently, some contributions came in to merge in more Realtek drivers into rtl8xxxu which is better in most accounts.
They deleted the staging drivers after this support was added.
So 6.5 and higher is very nice for some USB devices. |

I wonder why it works for me on Arch (with 6.1) and not on Gentoo then. |
