Need help losing sporadically internet connection

[elcoyote189]

I have a PFSense router running in a Windows server 2016 hyper-v, 8GB ram, 4 Cores, and Lan and Wan coming out of a Syba SD-PEX24033 NIC pci-e. It is directly connected to My Verizon Fios ONT box I do get a WAN IP I can also see all the devices on my network but at times my internet connection drops where I can access nothing other then my other machines and after certain amount of time it will work again on its own.
