Adding support for USB WiFi TP-LINK TL-WN821N(V4) with Realtek RTL8192CU?

[Wallace Au]

Hi,

I am new to ChromiumOS/Linux building and trying to get my onhand platform work... It is a ZOTAC ZBOX ID18 with Intel Ivybridge 1007U CPU, the factory config is without WiFi. So I plug the USB WiFi TP-LINK TL-WN821N(V4) with Realtek RTL8192CU chip.

I tried the default ChromiumOS amd64-generic build but with no luck, the WiFi is turned off as the following screen:

Then I went through the following kernel reconfig to include the RTL8192CU driver but still not fixing the problem:

- run cros_sdk

- run ~/trunk/src/third_party/kernel/3.14/chromeos/scripts $ kernelconfig editconfig

- Set"Networking support-->Wireless-->cfg80211 - wirless configuration API=Y"

- Set "Networking support-->Wireless-->Generic IEEE 802.11 Networking Stack=Y"

- Set the "Device Drivers-->Network device support (NETDEVICES [=y])-->Wirless Lan(WLAN [=Y])-->Realtek rtlwifi family of devices" to "Y"

- Guessing it might be required, I tried "kernelconfig oldconfig" here

- run ~/trunk/src/scripts $ ./setup_board --board=amd64-generic

- run ~/trunk/src/scripts $ ./build_packages --board=amd64-generic

- run ~/trunk/src/scripts $ ./build_image --board=amd64-generic --noenable_rootfs_verification dev

- run ~/trunk/src/scripts $ cros flash usb:// amd64-generic/R39-6258.0.2014_09_16_1753

- boot the USB pendrive

Anyone can help me out?

Thanks!
