Hello, I have 3 KC200 cameras on my home network. I have been experiencing intermittent network / internet connectivity issues on my home network since installing them. After troubleshooting devices (like laptop, iPhone, Apple TV, etc.) I discovered they were getting a DHCP offer with an invalid gateway address - and finally narrowed it down to every time, the gateway address was one of my KC200 cameras. After unplugging all 3 KC200's, the issue resolved.
It seems a DHCP server is running on this firmware version. Another user reported this as well, and I tagged onto that post with my firmware version; hope this helps.
