1. A gateway device comprising:
one or more processors; and
a non-transitory storage medium storing instructions executable on the one or more processors to:
monitor accessibility to a network from the gateway device via a physical uplink based on sending a first probe request at a first frequency, wherein the physical uplink comprises a wide area network (WAN) physical uplink;
monitor accessibility to the network from the gateway device via a virtual uplink based on sending a second probe request at a second frequency that is different from the first frequency, wherein the first frequency corresponds to a first time interval, and the second frequency corresponds to a second time interval that is different from the first time interval, and the virtual uplink comprises a local area network (LAN) connection through a switch;
based on receiving a response to the first probe request via the physical uplink and not receiving a response to the second probe request via the virtual uplink within a threshold period of time, mark a status of the physical uplink as reachable and a status of the virtual uplink as unreachable;
use the physical uplink to maintain data transmissions to the network from the gateway device;
suspend or stop connections via the virtual uplink to remove data transmissions to the network from the gateway device via the virtual uplink; and
continue to monitor the accessibility to the network from the gateway device via the virtual uplink.
