Tried to flash from 7.1b3 back to 6.48, it does shows up in Netinstall and I clicked the 6.48 file, it shows uploaded 1 package, then the device went reboot, after reboot it was still staying in 7.1b3, and when I wanna do Netinstall again, I can't find any devices in Netinstall anymore.

It can still boot up and perform normally in 7.1b3 now, but just can't do Netinstall anymore. Tried Netinstall version 6.48 and 7.1b3, still no luck.

Has anyone got the same experience or idea?

Thanks

On the positive side, everyone who purchased Chateau12 is stuck with ROS7 only. To be honest, for home or small office, ROS7 is perfectly fine.

Netinstall should still work tho.

Solved by using 192.168.1.x instead of 192.168.88.x, it's weird since I never use this IP range, my config IP range is 192.168.0.x.
