Linksys router not routing...

[TANAC]

I recently reset my Linksys router. Now it no longer allows my pc to connet to the internet( it is hardwired from router to computer.) I no longer allows my lap- top to connect to internet (wi-fi), BUT it does allow my ROKU to connect to watch movies and stuff (wi-fi).
It it did not work on the roku, that would make sence. but why on that one and not the others?
thanks for all ...

I reset this device again, and it still will not connect to anything but ROKU. ( I love ROKU) but the PC and laptop are still off line. Does anyone know why? I know it is something to do with settings (probably on the router page. ) but all of those settings seem to be set right.
