I am the librarian of the public library in Plainview, Texas. We were recently forced to change from DSL service to cable because the DSL broadband provider went bankrupt. We purchased a Linksys cable/dsl router (model BEFSR41, ver. 2) and after our third router, this last directly from Linksys, we are still experiencing intermittent Internet connection. I have spent many hours on the phone with Linksys but still no workable solutions. We use a fixed IP and the cable company swears it's not their problem and I believe them because when Internet service goes down, I am unable to ping the router. The router will come back up on its own in a few minutes (or faster if I unplug it for a few seconds) but it may operate for a couple of hours or only a few minutes before crashing. We have a 25-computer LAN but seldom are more than a dozen people online at any one time and crashes have occurred with a single user online after hours. Any suggestions. Right now I've lowered the MTUs to 1000 but I'm grasping at straws.
