I've had cable internet (Road Runner) for a few years now. Overall very reliable, but fairly often (daily) I seem to lose my connection for just a few seconds. I know it's on my end because I'll lose connection to everything all at once. All my software programs will log out, then log back on again. Just yesterday I added DSL as a backup, and I've already seen the same thing happen twice within a couple hours. I was hoping this was a problem unique to my ISP, but now I'm guessing this is a common problem. Does this happen to anyone else? Is it caused by my ISP, or could there be another cause?
