I've been trying to setup my deco unit after resetting it. After I set it up, I am unable to connect onto the wifi whatsoever. My modem works perfectly fine and has a stable internet connection but my deco unit always shows red and doesn't seem to connect onto the wifi like it's supposed to, I have resetted it multiple times, tried multiple setups and it's the same issue. Does anybody have any idea how to solve this? I have an AC1200 model - From South Africa.
