Laptop constantly bumped off wireless home network

I am constantly bumped off my wireless home network when I'm on my laptop. As we're planning on getting our 2 girls dell notebooks for Christmas, I want to get this issue resolved so they can access the network too. I have a good Netgear router and a modem issued by Time Warner's High Speed Enhanced broadband.
Also like to know how/what I need to hook up my home printer to my network/currently just home desktop.

any help would be appreciated.
