In Client mode - Can't obtain IP address from connected AP (using kernel_version branch)

[maggieroxas]

I am currently having problems with my wireless device (with its own ARM microprocessor) installed with 8723au module, running in Client/STA mode.

I have the following setup:

• rtl8723au module: 8723au with 2.4Ghz
• rtl8723au driver: kernel_version branch as of Feb. 27, 2014 commit
• Linux Kernel: v3.13.5
• File System: Ubuntu 13.04 (Raring Ringtail)
• Platform: ARMv7

I cross-compiled the driver (with my device's platform's compiler) using my Ubuntu 12.04 PC as host and across kernel v3.13.5 source codes - NO problems in compilation (make clean && make all),

I copied rtl8723aufw_*.bin to my platform's file system, specifically at /lib/firmware/rtlwifi.

I copied and installed the created 8723au.ko in my platform's file system, via "insmod 8723au.ko debug=4" - NO problems in installation.

But I had problems for 8723au as Client or STA.

I can:

• Turn wlan0 up (via "ifconfig wlan0 up")
• Scan nearby Access Points (via "iw dev wlan0 scan")
• Set my wlan0's mode (via "iwconfig wlan0 mode managed")
• Connect to an unencrypted Access Point (via "iwconfig wlan0 snakecentral")

But I can NOT:

• Get IP from the Access Point I've connected to (via "dhclient -v wlan0"), because it times out.
