In the past few weeks, I've developed a problem with my cable modem. About once a day, it drops the internet connection. I have a Cisco cable modem connected to a Linksys 8-port wired router that is 7 years old. I've had this combination for several years with no problem. The only way to get the internet back is to cycle the power on my modem and router. I checked for a firmware upgrade for my router, but I have the most recent firmware available for my hardware version. My ISP, TWC, has checked the modem and says it is working properly. The last time my internet connection went down, I connected my laptop directly to the modem and could not get on the internet. I went into the router's software and the IP address showed as 0.0.0.0. Oddly, when we recently returned from being out of town for Thanksgiving for 5 days, we were still connected to the internet. We have a laptop, two iPads, three iPhones and an iPod Touch that all went with us on the trip. As soon as we returned, the problem returned. That makes me think that one of our devices is causing the problem Any ideas what is causing this? Is it possible the router is dying and is causing the modem to drop the IP address? Thanks.
