Has anyone ever had wireless connection problems in house that has more one floor due to the metal duct work for the heating and air conditioning? I've been using a shared connection when the modem and router over in the next room same floor level. But mother computer is wireless also but had driver verizon drivers and wireless router drivers but had trouble slow connection since hers was upstairs in a bedroom. I had no trouble. Now few weeks ago mom decides to move the modem and router to the same room as her computer but I'm having the slow connection problems and she isn't. My guess is the metal duct work. This a split level house. She has norton 360 and I have dr webbs. Any suggestions?
