I have an issue to connect my sonoff devices to my capsman wifi network. The problem is, that these devices just can't to connect. BUT, the big BUT. I used to have simple wifi, not CAPSMAN and all works good. I can't understand what's the difference? The range is same, frequency is same, wifi type is same! Maybe something wrong with routes, but it's just a suggestion. And by the way, when i make hotspot on my cellphone using mobile data connection, all works good!
Please anybody give me a piece of advice, in which way i need to dig in to find a solution?
