Any hacker who is "sniffing" your non-encrypted WiFi traffic must be in physical proximity to your cable-modem, e.g., in a nearby residential house, or inside an automobile parked on the street, or a pedestrian on public property adjoining your home. How likely is that to happen?
Once your device has securely connected to the secure-HTTP page, where you enter a password, the password that you send is encrypted by your computer, and decrypted by the cable-modem.
Check all those "action-movies", where a president walks, insecurely, to the bullet-proof limousine, and then is secure when inside of it. There's only a small window-of-time where somebody can approach the president.
Similarly, the non-encrypted network traffic contains no confidential information, such as a password. The password is sent over a secure connection.
These are not the droids that you seek -- there's nothing to see; move along.
