Any mysterious connections showing in the logs? What is the uptime of the router?
Either way, change the username and the router password.
No mysterious connections that I can notice but maybe this isn't where to look. Also, it had been up a month and a half, bought the 88 on November 1st. I rebooted PC, cable box and the 88 before noticing radios were off. Weird that there isn't anything until last night:
