Can a wired router and wireless router work simultaneously?

I already have a wired router connected to my pc. I wish to connect a wireless router too to this PC. Will the two routers work at the same time or will I have to disconnect one of them, in order to work with the other? Will I have any internet connection problems if the two routers do work at the same time? Any help will be appreciated. Thanks. |||You should never use 2 routers on the same connection as they can cause conflict. Either replace it with a wireless router (it will also have a wired connection) or better buy a wireless access point and connect this to one of the ports on the existing router. This gives both.|||switch off the DHCP server on one of the routers otherwise, they will conflict with each other!
