We have done the troubleshooting to make sure the pc wireless card is working. It is. Pc can connect using Ethernet cable but not WiFi. Hp says to contact ISP
The two WiFi bands have recently been combined into one with the Comcast gateway devices. Some devices get confused and don't know how to see / talk to combined bands.
If you are not using any Xfi Pods, you can try separating the 2.4 and the 5.0 bands and give them two different broadcast names / SSID's;
Associate the PC with the 2.4 or the 5.0 (whichever one works) band's SSID (broadcast name) and password.
