I just changed my internet provider from DSL to cable. When I hooked up the DIR-615 I had some difficulties. At first my computers would all connect to the router but there was no internet connection. I had to download the latest firmware and install it. After the install succeeded, everything seemed to be okay. However, I now occasionally get the message that the connection to the server was reset while the page was loading. Also, the little world symbol on the router constantly flashes at a rapid rate. Before the switch, neither of these two things happened. When I check the download speed it seems fine. The cable modem is an Arris and also handles my telephone service.
