I moved to a new two story house that is an old farm house not that big. It is about 300 square feet larger then my old mobile home that I lived in before. I had a d-link wireless router dir-625 that I used in the old house and got full signal even to over 100 feet outside the house. My ISP is comcast cable in both locations. I used the same router in the newer house upstairs and often can not even get signal across the hall in the next bedroom over. However, at times I can get signal down stairs in the living room. I can have signal one moment that is full strength and the very next moment have nothing at all without moving. I thought my router may be giving out so I tried an apple airport express since my laptop is a mac. Not quite as bad but still the same problem. Signal goes from full to nothing without moving. Internet access goes from good to poor too.
Is this bad luck with wireless routers, cable modem, or could my macbook wireless card be giving out? The laptop is less than 3 years old. Or is it the house?
So if you know which it is, how do I correct this?
I have a dell desktop attached via ethernet and it seems much more stable although the internet is buggy at times too. My old place was the same ISP, same equipment and never missed a beat. The connection was perfect everyday all day. What has changed?
