Conky is slow in detecting network, after resumption from sleep

Conky 1.10.9_pre Linux Mint 19 Cinnamon

It seems the network is up quite a few seconds before Conky detects it, and I did not have this problem with the version of Conky in Mint's repositories, but it may be that some other update - to polkit, perhaps - is the source of the problem.
