What is the maximum length of a wifi access point's SSID?

Solution 1:

According to the documentation of the standard, the length of an SSID should be a maximum of 32 characters (32 octets, normally ASCII letters and digits, though the standard itself doesn't exclude values).

Some access point/router firmware versions use null-terminated strings and accept only 31 characters.

Here is the paragraph defining from the IEEE standard document :
