In the past few weeks I have noticed that on occasion my internet surfing would suddenly stop or pages wouldn't load. When I looked over at my cable modem I noticed it shut down and then the lights would come back on and I could continue. However, today it has consistently shut down and come back on, shut down come back on, ad nauseum. Even when I am not online and I shut off the internet connection it will still shut-off completely and then power on. I checked all cables and power attachments and they are solid. This modem is connected through my Lynksis router via network connection (as opposed to USB). The router remains fully powered as does the rest of my PC. Only my modem seems to be sputtering, stopping, and restarting. I checked device manager and it is clean. I ran spyswepper, NOD32 anti-vi (nothing found), and I haven't loaded anything new nor have I changed any applications nor have I changed hardware. Basically my internet habits are the same. I also have a firewall. This modem is about 4, maybe 5 years old and has never given me a problem. Can modems go like this? I have never read of anything like I am experiencing now. It shut down twice as I wrote this.
