WiFi will not allow certain WiFi Cameras to connect
I've been having a lot of trouble with SimpliSafe wifi cameras, and now one of Ring's wifi cameras, and have exhausted my tech support options at Ring, SimpliSafe, and with my ISP Cox. Multiple wifi cameras work with no problem, including the Ring doorbell and the Ring Battery Stick-Up cams. SimpliSafe's SimpliCam worked for awhile, then lost connection and wouldn't reconnect. SimpliSafe sent replacements, which worked for maybe 10 minutes before disconnecting and refusing to reconnect. Our current problem is trying to get Ring's Indoor Cam to connect.
The other Ring camera devices work fine. The Indoor cam refuses to connect to the same network. It will connect to a hotspot network. For troubleshooting, I have tried moving the camera to be close to the router, moved the router from any obstacles, ensured I was using the 2.4ghz network (5ghz is on a different name), ensured the SSID and password were not overly long and did not have symbols, turned off the router firewall, created a guest 2.4ghz network, restarted the camera/router/modem many times. It was also the first of the cameras that I tried to set up, so I don't think it is any sort of device-limiting going on. I don't have any sort of MAC address restrictions or other network lockdowns in place, unless there's some deep-menu setting that I somehow tweaked.
There seems to be some weird interaction of these certain cameras and this router. Ring's advanced tech support hadn't come across an issue like this before. Aside from buying a new router, I am out of ideas for troubleshooting. Any help is appreciated!
