Thanks - doing the reformat/reboot option fixed it. Maybe there will be a firmware fix in the near future.

It's set to loop when the SD card gets full - I still have recordings from previous months. Any ideas what is causing this and how to fix it?

Had some relatives at the condo and asked them to unplug the AC adapter, then plug it back in - the 511W came back online without using the ethernet cable approach!

I think the RLC-511W has the same problem.

I had a 511W setup outside back in January and after 1 month it suddenly was no longer accessible. I had to remove it from its outdoor location and connect it to the router using the camera's ethernet port and I got it working again.

Unsure about that camera, I mounted another 511W outside but closer to the WiFi signal at the end of April and as of today, it also has suddenly gone offline also about a month after it was setup.

I don't think there is a firmware update available yet for the 511W.

I plan to reset the camera in a few weeks (8-hour drive) - wish there was something different I could do to make it stay connected for longer than a month.
