This sounds more like your wireless router sucks. If it’s a combo modem/gateway from spectrum look into buying a separate modem and mesh network. Unless that messes with your sweetheart payment. Otherwise, you would probably be able to just put a mesh network onto current gateway with Ethernet and disable WiFi on old equipment. Maybe. Lots of possibilities to explore.
