Hi every. I have an usb wifi card with rtl8821, now we can compile the driver to generate the .ko. then i copy the file to the openwrt, then insmod the module. it can display two interface, one is wlan0, the other is wlan1. I can use one interface to take as client to connect with AP, I also can access internet from local machine my problem is: I could not use the wifi detect tools to find wifi interface, so the file /etc/wireless is empty, So I couldn't use luci or uci command line to let wlan0 to jion the wan zone, So I couldn't use it as regular router to connect with other device , Can anyone give some suggestion about it? Thanks
@ninesuntj, welcome to the community!
I beleive this chip is client only...no AP.
then vendor provide the latest driver code. you can get both AP and STA after compiling it. we can see two interface :wlan0,wlan1
then add it to the source tree, additional sets of hands are always appreciated.
sorry. Such codes is licensed, we couldn't upload it
then how would you expect us to do it ?
can you give us some suggestion about it? because the etc/config/wireless is empty. can I add the wifi config mannually or modify the relative script to get right etc/config/wireless
could you please recommend me replaced one?
usb wifi stick as AP ? avoid it, if you can.
if not, read Best 5GHz USB Wifi Adapter to Work with OpenWrt
whatever you choose, don't go for Realtek.
I agree with those talking negatively about Realtek USB WiFi support. Just avoid Realtek.
I maintain a Github repo with information about USB WiFi adapters to be used with Linux:
Here is another link where I give information about using a RasPi4b, hostapd and a mt7612u chipset based adapter to set up an AP. This setup works really well:
