This metric is expected to be constant, unless device is reconnected: it merely takes content of /sys/class/net/wan/speed and converts into bytes/s (original in Mb/s). And AFAIK, content of this file is kept constant once connection is established.

Regarding your need: to get current speed on the interface you can use something like irate(node_network_receive_bytes_total{device="wan"}[5m]) and irate(node_network_transmit_bytes_total{device="wan"}[5m]). Depending on situation you might need to switch to rate and adjust range selector, though.
