I’m not really sure about Cable Internet, but if you have DSL Internet and your connection keeps spontaneously dropping, it’s possible that the modem is going bad even though it appears to work perfectly fine. I’ve been dealing with the connection dropping for awhile now, and I thought it was just the ISP, but I was wrong. The modem was 3 years old and nothing seemed wrong with it. It wasn’t until I got a new modem that it all made sense. I’ve been continuously connected for 3 days now and not once has the connection dropped. So just thought I would put this out there for anybody who has DSL.
