Would plugging a new wireless router into a normal router work? or are there other ways or converting an old 1?

Trying to perswade my parents to get a wireless router... but need help :)


is is possible to plug a wireless router into the back of our current one create a wireless signal? cheers|||Buying an entirely new wireless router to replace a current router would be a more effective solution than simply plugging in an antenna to to the current router. Also, a new router would have speeds and coverage 10x that of an antenna.|||The wireless router should totally replace any previous router. All of them support both wired and wireless access connections.
