Doorbell not connecting to the wifi - first install

Hey, I tried to connect ring doorbell 1 to Tp-Link VR600 2.4 wifi network. After the ring is connected to the wifi, the left white light is turned on - "no internet connection".I tried a lot of things to solve to the problem:1. To ensure I get a stable connection in a few other devices on that wifi network.2. Change the wifi channel from auto to 4 and Channel Width to 40m and 20m.3. Factory reset the ring.4. Disable iPhone cellular data.5. Open a new 2.4 guest network.6. Fully recharge the ring.7. Empty the battery and recharge it again.In every step, the ring does not get a connection to the internet.What can I do to solve the issue?Thanks-- Ori
