Emo-Fi

Emo-Fi is your turbocharged Wi-Fi menu bar utility. It lets you view more Wi-Fi information than is available with the built-in dropdown.

You can discover various network attributes at a glance, such as encryption, 5Ghz or 2.4GHz band, and generation. Additionally, you can view the connected Wi-Fi network IP address, router IP address, public IP address, and signal strength.
