I used to work for a networking start-up and when we were in the US trying - without success - to sell the company we practised over and over saying "roWter" for "router" (English pronunciation like "rooter").
isn't English fun !
(For real though we don’t use that word for argument or whatever.)
Router (rooter) the thing that routes packets in a newtwork
Router (rowter) a machine tool that cuts grooves, etc., in wood or metal.
