Currently I have 3 computers on my network, they are all wired. This is what happens after about a week of being on the network and connected to the internet, all of a sudden in the morning I cant get online from any of the computer. I have Linksys router, model BEFSR41. What I figured out is that I need to connect one of my computers directly to the dsl box, then get online on that computer, surf the web. Then I reconnect my dsl box to the router and all the computers are able to get only. What is causing this? What do I need to do so that I dont have to do that?

Thanks for your help in advance.
