1. A computer-implemented method, comprising:
determining a decreasing sequence of scan ratios, each scan ratio indicating a proportion of time over which a mobile computing device scans one or more frequencies to attempt connection with a wireless network during a disconnected time window when the mobile computing device is disconnected from the wireless network;
determining a connected time window when the mobile computing device is connected to the wireless network, the connected time window occurring after the disconnected time window;
determining a ping-pong rate for the mobile computing device based at least on a duration of the connected time window;
selecting a scan ratio from the decreasing sequence of scan ratios based on the ping-pong rate; and
scanning the one or more frequencies in accordance with the decreasing sequence of scan ratios and starting from the selected scan ratio to cause the mobile computing device to attempt connection with the wireless network.
