By the way. Its normal for your router to fail now an then(logjam). All thats usually required is for you to hold the reset button for several seconds and your good.  Also your PC isnt supposed to recognize your router(and it won't). Well okay it'll recognize the IP but thats not your router tyhats all setup on your PC first..  But it does need to recognize your NIC(ethernet card). Reinstalling drivers for the NIC should have resolved that. But hey, now yu can start again with a brand new fresh drive.
