Wifi extenders have been in the market for a while now. Most of the homes in the United States complaint that even after signing up for the best internet package, they are not able to get the desired internet speed. There are some areas of the house where the connectivity is as bad as zero. While the most powerfull routers are unable to reach these areas,the introduction of range extenders has made the connectivity possible in these dead spots or areas.
