LF: WIFI Surveilance camera recommendation

[Reef Pilot]

I have a Foscam and it worked great for several years. Then I changed my router, and be darned if I can get it working again. I attached it directly with a lan cable, pushed the reset button, etc, but for some reason it just won't connect (be recognized by the router). I tried my old router again, but it doesn't see it either anymore. So no idea what is wrong, but looks like it is just an ornament now.
