Can anyone recommend a working firmware for the 2865 that won't reboot its self every few days?

Debug below if anyone is interested;

My 2865ac is running 4.4.1 and currently has an uptime of 475hrs.

Thanks - will give that a try sometime over the weekend. Oddly I'd not noticed the till I was logged in doing maintenance on a handful of devices and the uptime was so low... (max of 6 days)

I'm sure there was posts on here about the newer f/w's having the same or worse issues, but your 400+hrs seems to be the best so far!

I have two, 916 and 530 hours currently. Both seem stable.

I'd also suggest 4.4.1, current uptime is 1776 hours (74 days) which is when it was updated.

If you still have issues it may be worth manually configuring from a factory reset.
