I have a four story house. My computer downstairs when I'm online or downloading, it uses up all the bandwidth of my router(2nd floor) and so my Laptop(3rd floor) and my game system(4th floor) can't get enough signal strength to get online. Plus my internet phone running through the router doesn't work from time to time. And my router does not have antennas. Should I try upgrading from a 6000 internet service to a 16000 or try boosting signal or create access point? Also, I don't know if something like this is available, but, is there a device that I can get, that if I put it on the 3rd floor or 4th floor will help to broadcast the signal evenly? Any Ideas that can help me out, is appreciated. Thanks
