I too had the same problem with my HP envy notebook. My laptop shows all wifi connections other than mine. I was using D-Link dual band router. I resolved the problem by changing the wifi channel to lower one(1-10). It seems Hp laptop does not recognize the channels above 10. So, please log in to your Wifi router and select the bandwidth (2.4 GHz.) and change the the bandwidth which is lower than 10. I hope this will solve the problem. Best of luck…..
