I have built a webserver running Ubuntu 12.04 64 bit. Works great and serves up my webpage fine but when connected to my ADSL router it crashes my internet connection intermittently 2 to 3 times a day. The only way to restore ADSL connection is to reboot the Thomson TG782 modem/ router. Not sure what is going on but this only happens when the server is on the network. Are their any known issues that will cause this.
