On October 23 I purchased a new dell laptop with windows 10 from Newegg. Due to not having internet at my home, I did not discover it would not connect to the internet until after my 30 day warranty from them had ended. I called Dell, they ran a diagnostic on it and said it was NOT a hardware issue. It sees my wifi, but will not connect. I have tried to connect to wifi in 4 different locations. Any ideas?
