However, one suggestion I would offer (and I know it's pretty basic) is to make sure in his TCP/IP settings that he's set up for DHCP automatically, and doesn't have any static configuration sitting in there.
In theory you shouldn't need to do much "installing from a laptop" to get the router set up. If internet is working on yours, just point your browsers at 192.168.1.1 (or similar - I'm not sure how you find the default gateway listing on a Mac) and you can edit any settings from there.
