AC87U randomly dies

Thanks for the suggestion. (Un)fortunately, no AV software/antispyware is running here.

I had exactly the same problem (firmware 380.64_2) and none of the solutions proposed here worked. But I think I discovered where is the problem. I disabled all the features under AiProtection - Network Protection and it's been already 3 days without reboots
