16.16 proved to be extremely unstable for us on an MX250. Also had the same problems with 17.3 and I believe 16.5? Constant disconnects from the cloud. Woudl completely go out to lunch and have to be factory reset. We are finally stable after support locked us back to 15.44. I've been through 3 new RMA MX250s and done countless factory resets. What a mess. I have a bunch of MX65 and MX68 running 16x and they work fine but no way on earth I'd load this on a 250 after the last 3 weeks of problems I've been dealing with.
