4.7.2 Connection Scan

The connection scan is run before a connection attempt. The process starts by running a fast scan cycle.

Fast scan: the purpose of this scan is to scan select channels to find and connect to a proper AP without scanning all 2.4G and 5G (and DFS) channels. Only select channels are scanned first, because a full scan could be a very slow process (more than 3 seconds).

The first step in this process is to decide which channels will be scanned. This selection is done by a rank algorithm which takes into account historical scan results, connection statues, link quality, and so forth.

After the Fast Scan completes, the system decides whether to connect to one of the candidates or to continue with the regular connection scan.

The decision is based on attributes such as: Priority, Security settings, RSSI, channel, and whether the candidate network was the last connected network. If a proper candidate was not found, the regular connection scan will follow.
