    So, over the last few days, my internet connection has been cutting out CONSTANTLY, and after much experimenting, trouble-shooting, and process of elimination, it is in fact NOT my router (yay!), but it is my cable modem. I have a Linksys CM100 cable modem, and I have the log files here...

    Sounds like either a signal/cable issue, or something on the ISP's end.

    Be best if you post this in a more specialized forum about networking though in your situation the first thing to try is calling your ISP since you are paying every month and rightfully deserve proper customer service.
