Due to Covid, everyone in our community is online at the same time. I have no issues with downlink but my uplink is horrible. I have the RT-AC5300 that seems to support a second WAN. In my case I don't want a second WAN as a fall over when the main goes down. I would like to purchase a second cable modem service and aggregate the two uplink bandwidths to improve my speeds. Does anyone know if this is a possible configuration and how to set it up (if it is)>
