Problem with hostapd (rtl8188cus, Linux kernel 3.20 32bit) #4

Closed ChangmingTian closed 8 years ago

ChangmingTian commented 8 years ago

I've built and insmod the driver without any problems with linux kernel 3.20 32bit AP is visible but I can't connect to it If WPA is enabled. It works well in AP mode with an unencrypted network.

I have followed this advice,but It is not work https://github.com/lwfinger/rtl8188eu/issues/94 ajeet17181 commented on 7 Apr 2015 I encountered the same issue and found that the sizeof struct ieee_param in kernel driver is 60 where as in hostapd it is 64. if I comment out following lines in rtw_set_encryption in os_dep/ioctl_linux.c (line number 4880) file everything works fine. I am able to connect with wpa2 and with WEP too.

if (param_len != sizeof(struct ieee_param) + param->u.crypt.key_len) { ret = -EINVAL; goto exit; }

As you learned, struct ieee_param is not wrong in this driver.

This driver is provided as a service. My only guarantee is that it will compile. If you want/need this driver to work in encrypted AP mode, you will need to find someone that you can pay to debug it. I have no time for such efforts.
