@Coco Xia, I poked around the LattePanda drivers - it appears that LattePanda switched from Broadcom on the v1.0 LattePanda (z8300 processor) to Realtek on the v1.1 and v1.2 LattePandas (z8350 processors. Which WiFi adapter do you have?

I found two sets of Broadcom WiFi adapter code, one in the 'All-in-One Pack' folder structure, the other in 'WIFI & BT\Wi-Fi BT Driver for LattePanda V1.0.zip'. There are differences in the .txt and .map files - not sure if these are important. I am going to re-install the drivers from these two sources and report back.

Thanks, Norbert

@Coco Xia, I ran the LattePanda install scripts in both driver folders - in both cases, the commands 'pnputil -i -a bcmdhd64.inf' and 'pnputil -i -a bcmfn2.inf' failed with "Failed to install the driver on any of the devices on the system : No more data is available." I could not find anything in the Event Viewer logs. I also attempted to update the drivers through Device Manager and got "The best drivers for your device are already installed".

I tried uninstalling the drivers via Device Manager and scanning for hardware changes to reinstall the driver - still no joy.

My suspicion is that the Broadcom drivers provided by LattePanda are not compatible with the Fall Creators Edition. I did a search on "VID_02d0 PID_a94d" drivers and finally found driver version 5.93.103.27 at https://drivers.windows10download.com/w ... bit-gjqqk/. I updated to this driver using Device Manager, disabled/enabled the WiFi adapter, and successfully connected to WiFi.

Problem solved!

Hello, I'm also one of the original backers and I have this issue. I'm not interested in downloading a driver from some random website, is it possible for the LattePanda team to provide a compatible Broadcom driver ?
