I'm new here, but concider myself well informed on most problems when in comes to tech problems. The problem im having is...I have comcast and have liked them so far, speed is great, reliablity is getting better for my area. Here is the question, I live in an older home, with plaster walls, "concrete and chicken wire" and I have low signal streagth for the wifi in certain parts of the house. What are some ideas for a better wifi or router in my home, that will give me better signal streagth. I'm using the router comcast gave me and I do have another router, it's a netgear N600 duel router.
