Hello,
I'm not an CS expert, so don't quote me on this.
When you change the HWD in a CS product, you also replace the LINUX OS, like in the DM1x00. If you use the CG150 as gateway it will take time. A long time.
You should be able to use WiFi, which is faster (nothing I have done myself, but I heard it takes around 2 minutes).
I'm not sure what happens after the update, if you just can connect with WiFi again or if you need to connect with CG150 and change some settings??
Here's a video about the CS10 and WiFi connection:
