HP Envy 7640 can's see some wifi networks

[kpgraci]

The windows 8.1 O/S may be 32 or 64 bit, not sure which (it is not in front of me).

The printer HP Enny 7460 can see and connect to other wireless networks, but it can not see my home cox wireless network, that is, the SSID is not in the list of available networks in the wireless setup.

The cox modem actually has 2 wireless networks with 2 diffierent SSID's, one is 2.4 GHz the other 5 GHz, the printer can see neither of them, my andriod phone sees only the 5GHz network, which I can connet to with my phone.

The cox wireless network is broadcasting supposedly the SSID for both networks.

There are several networks listed in when I go to wireless setup in the printer, but they are the surrounding neighbor's, not my cox network.

I spoke to cox support and they confirmed that the modem was functioning properly, there are no MAC filters, and the SSID is being broadcast.

So it may be that the printer will not see a 5Ghz network, I don't think they existed when the printer was made, but it should see the 2.4Ghz network. I cannot confirm that this 2.4 Ghz network's SSID is being broadcast but the cox people say it is. The 5Ghz SSID is being broadcast.

If in fact the 2.4Ghz SSID is NOT being broadcast then this is the whole problem, but I believe it is, so is there any reason the printer would not see my network?  Would the wiresless security mode (WEP, WPA2, etc) have anything to do with it?  (The cox modem uses WPA2).

Thanks!
