Rtw_8821cu driver loading exception. #200
Comments
|
RTL8821C, RTL8822C, and RTL8822B with USB or SDIO interface are not working well in AP mode with this driver. |
Oh, thank you for your answer |
|
I applied the patch [1] (wifi: rtw88: usb: unbreak multicast) from mailing list on this repo and AP is working now on my USB stick with 8822CU chipset. |
|
There is active work on the USB part at this point, I see; |
Can it be used in openwrt kernel version 5.10 or above? Now my error is that on the openwrt kernel version 5.10.201, the 8821cu module can normally receive WiFi when the board is turned on, but it is useless to disconnect and restart WiFi after a while. |
Thank you for your reply. Can this patch be used above openwrt kernel 5.10? |
In addition, downloading drv rsvd page and firmware failed, and I don't know where they were downloaded. The following is the error log.
