Like Jamie, I've been having problems with my Dynalink RTA1320 modem/router. I ended up replacing it with a Linksys AG300. That seemed to fix the problems, but ... about once per day access to the Internet gets cut off. It's easy enough to restore functionality. All I have to do is (a) power off/on the modem/router, or (b) disconnect/connect, or (c) add my ISP's DSN servers to the network tables on my computer. In other words, it appears to be a DNS problem. The question is what's happening? I've put my ISP's DNS addresses in the router/modem's setup (makes no difference). When DNS name resolution via the router fails, all computers on the network fail to access the Internet. The timing of the problem doesn't coincide with the monitored with the monitored burglar alarm "phoning home". Any suggestions on what the problem is or what to try next? Michael
