I have a Blink camera system, the Sync Module is Gen1. (the one on the left: https://support.blinkforhome.com/en_US/using-your-sync-module/sync-module-reqs)
I switched to Three 5G from BT. I tried to reconnect the Sync Module to the router it says "password error". It is not because of the complicated passwords requirement. I tried the same password on a powerline access point (TP-Link WPA4220) and it connects to that fine. The security is WPA2 with AES.
I have tried separating the 5GHz and 2.4GHz WiFi bands, and even turning off 5GHz band for a test and use exclusively the 2.4GHz bands. Also I tried WPA/WPA2 and WPA2 for security.
BTW the error on the Sync Module is always "check your password", for any kind of failure, really. Even if I set a non-existing network.
So:
- all my other devices in the house work with the new Three router
- the Blink Sync Module works with any other router (old BT routers, powerline AP, ASUS router etc)
- just this pair doesn't work: Blink Sync Module and the Three router
I did talk to Blink for the last 2-3 weeks. There's a guy who answers every 3 days and keeps telling me nonsense like "call the ISP to configure your WiFi as 5G interferes with 2.4G" 🤡
Anyone can give an advice? There have to be some people who have Blink and Three, and made it work, right? Thanks!
