 Since the pre-built SD card image might not have the latest bug-fixes/updates, it is recommended to update the driver on board.
 - Prepare Analog Devices Linux kernel source code (only need to run once):
  ```
-  $OPENWIFI_DIR/user_space/prepare_kernel.sh $OPENWIFI_DIR $XILINX_DIR ARCH_BIT
+  cd openwifi/user_space; ./prepare_kernel.sh $XILINX_DIR ARCH_BIT build
  (For Zynq 7000, ARCH_BIT should be 32, for Zynq MPSoC, ARCH_BIT should be 64)
  ```
  **Note**: In Ubuntu, gcc-10 might have issue ('yylloc' error), so use gcc-9 if you encounter error.
 - Compile the latest openwifi driver
  ```
-  $OPENWIFI_DIR/driver/make_all.sh $OPENWIFI_DIR $XILINX_DIR ARCH_BIT
+  cd openwifi/driver; ./make_all.sh $XILINX_DIR ARCH_BIT
  (For Zynq 7000, ARCH_BIT should be 32, for Zynq MPSoC, ARCH_BIT should be 64)
  ```
 - Copy the driver files to the board via ssh channel
  ```
-  scp `find $OPENWIFI_DIR/driver/ -name \*.ko` root@192.168.10.122:openwifi/
+  cd openwifi/driver; scp `find ./ -name \*.ko` root@192.168.10.122:openwifi/
  ```
  Now you can use **wgd.sh** on board to load the new openwifi driver.
  **Note**: If you have symbol or version error while loadng the driver, it could be because the kernel in the SD card image is too old. In this case, you need to follow [[Build openwifi Linux img from scratch](#Build-openwifi-Linux-img-from-scratch)] to generate your new SD card image.

 On the other hand, the wpa_supplicant program on the client side (commercial Wi-Fi dongle/board) cannot suppress 802.11b rates out of the box in 2.4GHz band, so there will be an issue when connecting openwifi (OFDM only). A patched wpa_supplicant should be used at the client side.
