I have a DSL line that I have going through a Linksys 4 port router. The speed fluctuates dramatically sometimes slowing down to a near halt or not working at all. A combination of unplugging the router, unplugging the modem, disconnecting and reconnecting in the router settings and just plain screaming obscenities sometimes fixes the problem. I have done a speed test on a site and it goes from an aprox 680 per second rating of "fantastic" all the way down to 50. Could there be a hardware problem with the router or modem? I suspect that it might be the router because when things are not working properly sometimes 192.168.1.1. in the browser window is unable to bring up the router settings page. I only have me and my roommate on the system. If he is using it would my speed decline substantially? I am about ready to switch to cable if I can't fix this. Thanks
