I'm having trouble installing my Cudy Wifi Adapter Driver (RTL8821CU) in the OpenWRT CLI! I've already installed all necessary usb-2 and usb-3 drivers? using kmod and so forth, so I have Open WRT installed and can login via the web browser. After I couldn't get the wifi adapter driver installed I tried to install it through the OpenWRT > System > Software menu where I got this error below...
I didn't! I was following the same video as you and just bought the same wifi adapter used in the same video!! lol I bought four of those adapters just to try to bond them together (channel bonding) in hopes of making the speed faster, but I doubt it'll work especially if the driver(s) won't work with the device!! lol
In OpenWRT 23.05, no the kmod-rtl8821ae module won't work with an rtl8821cu USB wifi dongle, I tried. No new device appears as listed with "ip a", however the kernel module "rtl8821ae" is seen as having successfully loaded with "lsmod". This is on a Raspberry Pi 4.
BTW: I installed "usb-modeswitch" and ran "usbmode" on the command line, as this dongle was in "Mass Storage device" mode at first. Seen in kernel log:
New USB device found, idVendor=0bda, idProduct=1a2b, bcdDevice= 2.00
usbmode changed this to:
New USB device found, idVendor=0bda, idProduct=c811, bcdDevice= 2.00
That still didn't help for a new device to pop into existence.
