Currently, the Circle device supports Wi-Fi network names (or, "SSIDs") and passwords with most special characters, as well as passwords up to 64 characters long.
The Circle device does not support the following characters:
- Leading "whitespace" (i.e., a space before the first letter/number/special character)
- Trailing "whitespace" (i.e., a space after the final letter/number/special character)
- Non-English alphabetical characters
Whitespace in the middle of the SSID or password should be fine.
NOTE: Earlier versions of the Circle device firmware did not support many special characters or lengths of over 50 characters for Wi-Fi names (SSIDs) or passwords. If you are running into issues and suspect that you may have a Circle device running old firmware (like recently powering it on after many months of inactivity), please contact our support team.
