I did have to call and get my system router, an very old Netgear RT314 to work but that was simple enough. One thing, though, When one does go through CERT's non-tech users site, one finds that tehy recommend bout a hardware (router) and a software firewall. Of course, they are talking about with Microsoft but I find it works with Linux, too. I use Linux but my wife does have a Win98se system which is almost never online. Since I do websites and am an IRC netadmin for deepspace.org, too, I did have to get my new IP registered with my host so I could log on with my O-line, hehehehe. I never did use the Roadrunner web site nor their e-mail and have no real reason to use Comcast's services, either, I simply use their IP throughput and if any problems arise, there is always DSL, but that is AT&T here in Houston, too.
