It's not affecting the sync, it just rebooted after 300 hours uptime.
I think I have figured out the issue.
I have always had the Sky Hub connected and 2 further hardwired 2.4 & 5Ghz AP's elsewhere in the house, so I have been serving my devices with 3 routers.
Long story cut short spilt liquid down one router and the other failed.
I now have at least 10 devices via WiFi with often around 15 - 20.
The Sky Hub cant keep up and it reboots.
In time I will get another 2 APs, but for now it's not a priority.
Word of warning for everyone: having 10+ devices on the SR102 means it'll reboot on its own accord. I've gone from 100% stability to this.
Overall, disappointed with this router now.
It's easily done getting this number of devices. There are 5 people in my house, all with at least 1 phone (some of us have work & personal phones though so 2 each),
7 WiFi enabled phones (3 are for work), 2 WiFI TVs, 2 Apple TVs, 1 chromecast, 2 Sky boxes over WiFi, 1 PS4, an xbox 360, 1 WiFi printers, 5 laptops personal, 3 laptops for work.
It really adds up. Obviously these things are not all on at once but usually 10ish.
