I have a Cisco 827H ADSL router. I have had to download Microsoft VM and install it on a machine to be able to use the web interface. If you use any other version of Java, the browser will not communicate with the router. I KNOW that I can telnet/putty into the router and use the command line interface, but it is so much easier to just use the web interface. I would like to do this from my linux machine as well, but don't know if there is a version of Java that is the same as the Microsoft VM.
