I am sort of a computer geek and have used home routers for more than ten years. I have found that for me, Linksys is the best. I have four computers currently setup on my home LAN. Two wired and two wireless. The wireless is reliable when within range but not as reliable as being wired. Routers are cheep and easy to setup. You should have no problem at all.
