I have a house ( 2 story with walkout basement) that was built in 98. The builder ran cat 5 to 5 locations throughout the house ( 2 on the 2nd story, 2 on the main and 1 in the basement). In the furnace room in the basement y I have a cable modem that feeds into a Dlink router and then out into the house. Would a wireless modem reach everywhere in the house. If so I am planning on replacing my old router with a combo one. If wireless will be problematic then can I simply plug a wireless modem in one of the main floor or second story outlets?
My laptop works in my garage, it's 120ft away on the other side of 2 feet of limestone.
Cisco WRT400N, there are newer and better ones now. It's about 2 years old
