If you open your browser and in the address bar type 192.168.2.1 on the left (can't remember off top of my head) there is an option for wireless, it will ask you to log in when you click on this, as default there is no password so just click login, the screens you are taken to, don't change anything just keep pressing next and the router will restart. As your going through look for the channel option, there are 12channels for you to chose from, try 8 1st, then try all of them individually ans see if any of them improve the signal. If not you will need a wifi extender. Is there somewhere 1/2way between your router and laptop you can put one of these?
