Check to see if this is only a wireless issue...
Connect your laptop by Ethernet connection.. and see if your speeds increase..
also check to see if other computers in your home have the same IP address if they do they are conflicting..To check that start command line
by just searching cmd
and hit enter and type in ipconfig
Another thing to check is that do you have a password on your wireless network like (WPA WPA2)..if not put a password on it..(This will help unwanted people from accessing your network)
Hope this Helps..
