Special Characters are not suitable as Wi-Fi Name and Password

Used Products:

When creating a filename or web URL, it is essential to avoid common illegal filename and directory characters since the web files will be viewed by numerous users who use a wide variety of operating systems (Mac, Windows, and Linux for instance) and devices (desktops, tablets, and smartphones).  The same rule goes well with the wireless name and password. A common  Wi-Fi Name/ Password would include 8 to 63 printable ASCII characters, while things would become more critical when various device groups are involved.



Here are some common suggestions when setting up a Wi-Fi Name/ Password that would guarantee as many as devices are able to join the network:

1. A password is 8–63 characters long. A password of 14 or 15 characters would be long enough to defeat most brute-force guessing.

2. Avoid Trailing and leading spaces (ASCII 0x20)

3. Be careful with certain special characters, such as # % & " $ £


For Wi-Fi Name/SSID

Knowing your WiFi name without the password does not help if someone wants to steal your WiFi. So you might just need to make your WiFi unique and tell someone clearly, it is not yours, and please connect to your own Wi-Fi!  And if you look carefully, you might see Available Networks are listed from A-Z when the wireless signals are almost the same. So a name starting with "A "would be easy to spot, such as "A Happy New Year".


While Special Characters such as ?, ", $, [, \, ], and +  are usually out of consideration.  An apostrophe(’) is very popular but sometimes, could be confusing for smart cameras, TV, and wireless printers, for example, Don’t use an apostrophe in your broadcast Wi-fi name!.

During further troubleshooting with our users, we also found some devices refused to connect to Wi-Fi when certain special characters are included in the Wi-Fi password:

Case One:  Special characters not allowed in Wi-Fi password

Most of the Smart IoT devices, like wireless cameras and speakers, are suggested to connect to a wireless network without special characters, like @ ^ & and  ‘(apostrophe).


Case Two: If non-Latin fonts don’t appear correctly

Non-Latin scripts, like "ò" or "é" are rarely used in system coding. Please make sure the Language & Region settings of the device match your preferred language.
