Hi Betsy, I believe that Lee is referring to the make of the network modem/router combo that the cable company provides it's subscribers for internet access.
It's actually called a 3Wire modem/wireless router combo, and it houses both a modem and internet network wireless/hard wired router with four ports. Not literally a 3 wire unit. Hope this makes sense. Victor Co-moderator Blind Movie Buffs List Guidedogs List
