I believe the statute of limitations has passed......
Long ago, when I used to live in San Diego, I had a neighbor who left his Linksys network unlocked at defaults and I would routinely log into his WiFi router to optimize his system unbeknownst to him.....change the default DHCP range, change the network channel he was broadcasting on to minimize his co-channel interference with the other WiFi networks close at hand (and move him away from the channel that I wanted to use.....), etc.
Many years later, I had an opportunity to introduce myself to him and "fessed up" to my actions.....he told me that was the best 802.11b WiFi network he ever saw and regretted having moved on to a later model router for 802.11g as it never performed to his liking (he didn't leave that one at defaults and unencrypted, so I couldn't work my normal magic on it for him.....).
