At least once a day I have to reboot my modem because my Xfinity service just decides to quit, sometime more than once a day. We pay handsomely for our Internet service and I find it very disappointing that it doesn't work any better than it does. I have the latest modem that Xfinity recommends so I don't think the problem is on my end. I am really tired of getting such poor service considering how much I have to pay. I guess the next step will be register complaints with the Federal Communication Commission and/or the Federal Trade Commission.
