I have recently bought a wireless LAN to use a second PC in another room. I was already using a router (internet sharing) for my 2 PC's. Now that I plug the wirless "air station" to the router, the connection of wired PC stops working. But the strangest is that it doesn't stop working immediately, but maybe after 15min. Then even if I turn off the wireless, I still have to reset (turn off then on) the main router to have the wired connection working again.

Is there no way of having a wired and wireless connection shared on the same router ?
