internet connection issue

[Skie]

Quick question about my net connection. 8 have cable, goes into a moto modem then to a linksy wireless router. From there I have two desktops, and 360 connecting wired and ps3 connecting via wifi. Problem is that the net on the desktops ranfomly cuts out. The thing is only one desktop drops usualy whiile the other has a great connection. I've replaced the ethernet cables and moved them cables between spots. Any ideas how to fix it? The net will usualy stay out till I reboot, but once rebooted it connects perfectly

Are you sure the Xbox or the the PS3 doesn't cut out? Is there constant data flowing back and forth to them at the time the PC drops out so you would be able to notice? Is the problem on one desktop or both desktops?

problem is with both desktop, one more than the other. And yea the internet will be 100% fine on one while other just completely drops
