I currently have three PC sharing my IP using a Linksys router. My problem is that I had all three PC's up and running for a few hours then lose their internet connection. If I run my cable from the modem directly to the PC it works, this is the second router I have tried both with the same problem , lost internet connection. Do I go for router number three ?

Check the Lynksys site to see if there is a firmware update for your model. That often is the solution.

I agree with the last message, a firmware update may be all that is needed.

One thing to note it that Wifi can be subject to radio interference. At my house, I loose wireless connectivity whenever my dishwasher drains. As soon as the motor stops, the wifi picks up again.

I've had great success with Linksys equipment. They also have great tech support and I urge you to call them.

You didn't say whether its wireless or not or any other diagnostics so its hard for us to advise further.
