Also, if the C7800 is the supplying both the hardwired and WiFi connections, how would the 5Ghz be performing at 325Mbps, while the hardwired is performing at 94Mbps?

the c7800 is a cable modem/router combo device. If the c7800 is getting full speed, the wireless will work fine. But if the cable connecting it to the pc isn't rated gig, is bad, or even the device isn't linking at gigabit, it'll only pull the 94mbps because of overhead.
that's why I'd check
1. the cable
