When I upgrade from old router G3100 to CR1000A, I had random drop out due to unexpected router firmwae upgrade. I even got my router replaced with the a new one , the same model, still the same issue.
I am 100% my router firmware version since I received he router is.
3.3.0.11
However, from system log:
If this is not a bug of the router, I think it might be a security issue - an attack can remotely send crafted firmware upgrade request - I am serious, I have been working in IT security for almost 20 years.
