Friend bought his first computer. What router does he need for AT&T DSL?

KISS.

Whatever ATT supplies should be more than plenty for him. Mine was a motorola. Pfft, he doesnt need "n". Overkill. Comes with a nice long password.

Should be a no brainer to setup.

I agree. If there's need for better local area speeds, n can be handy. However, from the gist of the OP, seems like this is a single computer connected to DSL for Internet access. Since most DSL users in the USA won't see speeds higher than 6 Mbps, and often times experience much slower speeds, even g should be plenty.
n offers other benefits besides greater throughput, chief among them being availability of the 5 GHz band, which offers more channels than g and no interference with other household electronics that use the 2.4 GHz band.
