Wireless network does not appear in list and was working the other day.

Hello,
I'm having connectivity issues using a WIFI dongle and Centos7. I have been using this configuration without issue for 2-3 months. Yesterday, my ISP changed some settings involving my modem / router and now the network is no longer appearing in the list of networks that I can connect to wirelessly.
All the other networks appear and the dongle can transmit as a wifi hotspot. The network still appears on the list of "known networks" but I cannot access it using the "connect to hidden network" function or by selecting it from the list as I did before. Tried the nmcli functions and my network won't show up in the terminal. Tried nmcli --ask dev wifi connect wifinetworkname and there's no SSID?
I have not been using linux for a long time and would appreciate any help!
