Send wifi from computer to router? Read more for details?

[Azuka]

The problem with this setup is that Routers are used as access points, but computers are not. You can connect one router to another via hard wire and extend the connection that way, but computers are not designed to broadcast.

I'm not saying this is impossible, but I suspect it would require special efforts by some very nerdy and savvy person to get things work in ways for which they were not designed.

If something like what you have attempted works, it would seem that you would also, and more easily, be able to share access by connecting your pc to another one via hard wire connecting the two. I don't think this works either.
