Ender 3 V3 plus ( WIFI conection)

I bought an ender 3 V3 plus and when configuring it when I get to the point of selecting the wifi it is not possible to advance, it does not let me advance so I cannot configure the wifi. Could someone help me solve this problem?

I beleive the. V3 and Plus use the 2.4ghz band on the router–not 5 ghz. Check if that might be the problem.

My Ender 3 v3 also couldn’t find a wifi signal or it found one but with very little signal and it kept disconnecting. In the end I opened it from underneath and I could see that the wifi antenna cable was simply disconnected from the card, I connected it and the problem was solved. Maybe the same thing happens to you, I suppose it’s a bad quality control at the factory.
