RTL 8188, Can't Make it Work

[idude]

I need some help with rtwn driver, I bought a usb wifi adapter with the "rtl 8188" chip thinking that would be supported by FBSD 14.2 but it's not being recognized by it. So I decide to include this line if_rtwn_usb_load="YES" in /boot/loader.conf and rebooted and ran kldstat and now I can the driver loaded:

30 1 0xffffffff8362a000 dff7 if_rtwn_usb.ko
31 1 0xffffffff83638000 19140 rtwn.ko

Running usbconfig I can see it also:

ugen1.3: <RTL8188FTV 802.11b/g/n 1T1R 2.4G WLAN Adapter Realtek Semiconductor Corp.> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA)

but if I run sysctl -n net.wlan.devices I don't get devices listed, I should get something like rtwn0

Does anyone know why?

Unfortunately there are different variations of the "RTL 8188" chip.

The supported RTL8188EE is a 46 pin QFN package, yours seems to report a RTL8188FTV which has a 24 pin QFN package. So it's a different chip, and it's probably different internally too.

I think you're talking about the PCIe version, I'm talking about the USB version.

Thread 'RTL8188FTV Frustrations!'

Feb 19, 2025

I recently attempted to purchase an RLT8188CUS after recommendation in this post. I went to purchase it. To my horror, after a very long wait, it eventually arrived, I tested it under Linux, Windows and FreeBSD, and all said it was instead an RTL8188FTV! Do I need to go out and get an RTL8188CUS, or is there any way to make my RTL8188FTV function at all under FreeBSD? bsdconfig didn't seem to like it much and just didn't recognise it. usbconfig reports it as an FTV but doesn't specify any driver or anything

I've seen some posts on this, but a lot are from quite a long time ago and I...

Edit:
8188ETV appears to be supported.

the chipsets are different (EE and FTV). you can look at the openbsd driver which supports both. there are enough differences in the code.
