Flint WiFi issues

  1. After updating to 3.207 I have WiFi issues, signals appear and disappear quite frequently.
    blue light on router starts flashing slowly and after couple of minutes WiFi signals appear again.

2- Sometimes it is not WiFi issue but there is no Internet connectivity. If I disable and enable NextDNS Internet connects again.

3- I have enabled GL DDNS but I can’t set it in nextDNS as in the router DDNS check I always get the message " Your DDNS is not effective yet. Please try later."
