An Essay Proving That The Same Wi-Fi Network Can Be Displayed With Different Name On Different Devices

The experiment on a router’s SSID shows that the same Wi-Fi network may appear with different names on different devices. The reason for this is that the special characters used in the SSID of Wi-Fi have different software different equivalents.

The author of the website called Hamptonmoore.com gave up the SSID of the Wi-Fi 6 supported Fios Home Router, instead of creating it from standard text characters, with a special character index you can see in the image below.

This was an interesting experiment because the 802.11 Section 6.3.11.2.2 published in 2012 accepts a maximum of 32 octets, and the special character that it chose for the SSID had a length of 36 octets.

36-octet special character set as Wi-Fi name

Since the router cannot specify a 36-octet character as an SSID, the particular character will be a xcc xb6 xcc x81 xcc x93 xcc xbf xcc x88 xcc x9b xcc x9b xcd x90 xcd x98 Converted from xcd x86 xcc x90 xcd x9d xcc x87 xcc x92 xcc x91 xcd to 97ccb6cc81cc93ccbfcc88cc9bcc9bcd90cd98cd86cc90cd9dcc87cc92cc91cd. After determining this interesting SSID, the author checked how the devices would ‘see’ the Router.

After checking why determining an SSID with special characters for the router is a ‘risky’ choice. Because almost all devices saw the Router with a different name. The devices that showed the router’s name as it should be were the Amazon Firestick with a Samsung Galaxy S8 running only Android 9.
