| |
Hello,
I have just moved from Linux 3.7.x to Linux 3.8.x because 3.7.x is EOL-ed. On an iMX233-OLinuXino-MICRO with USB WiFi adapters I got the following problems which were never present in Linux 3.7.x.
Error 1: At first I used a USB-WiFi adapter with the RTL8192CU chip. The rtlwifi driver showed nothing wrong in dmesg. However, I could get nothing when scanning for APs. It looks exactly like there are no AP at all. Of course I could not associate with my AP either. I also tried to use the manufacturer's driver, same problem.
Error 2: Then I changed to use an adapter with the RT5370 chip. This time I got scanning working. It can also associate with the AP and works as expected. The problem is -- when I tried to add the wlan IF to a bridge, I got this: "can't add wlan0 to bridge br0: Operation not supported"
Here are some of my kernel config options: CONFIG_RT2X00=m CONFIG_RT2500USB=m CONFIG_RT73USB=m CONFIG_RT2800USB=m CONFIG_RT2800USB_RT33XX=y CONFIG_RT2800USB_RT35XX=y CONFIG_RT2800USB_RT53XX=y CONFIG_RT2800USB_UNKNOWN=y CONFIG_RT2800_LIB=m CONFIG_RT2X00_LIB_USB=m CONFIG_RT2X00_LIB=m CONFIG_RT2X00_LIB_FIRMWARE=y CONFIG_RT2X00_LIB_CRYPTO=y CONFIG_RT2X00_LIB_LEDS=y # CONFIG_RT2X00_DEBUG is not set CONFIG_RTL8192CU=m CONFIG_RTLWIFI=m CONFIG_RTLWIFI_DEBUG=y CONFIG_RTL8192C_COMMON=m
I will post more information if necessary.
Best regards, Guan
