I am able to connect the Cloudhub to wifi that has a simple password.
When the password is complex, the access point accepts the password blindly, but upon restart cannot start the wlan network interface. This password is very long, has single quote characters (e.g., '), has embedded spaces and a few punctuation characters. I suspect it is the quotes or the length which is the issue.
Unfortunately the raspberry pi 3 B+ does not respond to the usb keyboard when looking at the terminal (and the network is down for ssh), so it's hard to debug.

The VirtualHere cloudhub firmware wont work on the 3b+ , only works on the 3B
Other than the console
Other than the console keyboard, it looks to work OK. I thought I saw some posts on this forum saying the firmware had been updated to support 3B+ (and to get it from the hardware page).
That said, I wonder if the password problem is more of a software issue than a hardware/kernel issue. I suspect it has to do with quoting special characters somewhere along the path or handling of spaces.
