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

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.
Thanks in advance,
Best regards,

I am running kernel 4.17.0-rc3 under openSUSE Tumbleweed KDE on a Toshiba
laptop, and controlling networks with NetworkManager. When I plug my dongle in,
the device connects automatically. The firmware I am using has the following md5sum:
aaef52a47852e599cbff63a3e7f96a94 /lib/firmware/rtlwifi/rtl8188eufw.bin
My dongle shows the following with lsusb:
ID 0bda:8179 Realtek Semiconductor Corp. RTL8188EUS 802.11n Wireless Network Adapter
Mine shows as an A-cut:
Chip Version Info: CHIP_8188E_Normal_Chip_TSMC_A_CUT_1T1R_RomVer(0)
Yours is a D-cut, but I would not expect any difference from that. The only
place that information is used is in the log entry shown above.
If you want to try a different driver, there is one at
