I have an HP ENVY 700 PC, got it in January and its time to figure out why I am constantly having to restart my PC all day long to reconnect to the internet. It just looses connection all day long. The 5 bars goes either to the little x and greyed out, or the big yellow triangle. My daughter borrowed it and she had no problem in her house for about a week. Router is Netgear and I have an Xfinity modem. Can someone guide me in the right direction. I have called Comcast twice and they see a strong connection.
