There are problems - maybe intermittent - with WiFi on akari, akatsuki, aurora and xz2c so I have removed the 5.10 builds for these devices from the download server. I recommend sticking with 5.9 until we can get to the bottom of this. I have uploaded some log files for the team to look at, but interpreting them is above my pay grade 
Similar problems are known and reproducible in v6 builds for these devices (which share a common hardware platform) which is why I was making v5 builds for them.
