Hello everyone, I am currently testing a USB Wifi dongle LM816 [1] on a custom platform based on an IMX6. My configuration: kernel from mainline: v4.14 driver: staging R8188EU firmware: rtl8188eu from linux-firmware, last commit a3a26af24e29c818ef9b5661856018e21a5c49fb When I tried to set the wlan interface up, it says that "link is not ready" and that's all. Because of that, it fails to scan available networks. Here are commands used and their output: # dmesg [...] [ 14.690152] r8188eu: module is from the staging directory, the quality is unknown, you have been warned. [ 14.703105] Chip Version Info: CHIP_8188E_Normal_Chip_TSMC_D_CUT_1T1R_RomVer(0) [...] # lsusb Bus 002 Device 004: ID 0bda:8179 <-- LM816 Bus 002 Device 003: ID 0424:9e00 Bus 002 Device 002: ID 0424:2517 Bus 002 Device 001: ID 1d6b:0002 Bus 001 Device 001: ID 1d6b:0002 # lsmod Module Size Used by Tainted: G dw_hdmi_ahb_audio 16384 0 r8188eu 401408 0 coda 61440 0 imx_vdoa 16384 1 coda v4l2_mem2mem 24576 1 coda videobuf2_vmalloc 16384 1 coda evbug 16384 0 # ifconfig wlan0 up [ 447.639524] MAC Address = 5c:f3:70:3d:5c:71 [ 447.653636] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready # # # iw wlan0 scan command failed: No such device (-19) Does anyone already have this issue with this dongle? If it is not the case, what is your setup? Which firmware? Which driver? Any help will be very appreciated.
