So for father's day I'm getting my dad a 802.11g wireless setup. I'm looking at the Linksys stuff, and I noticed that I can get the Linksys g router and AP for less than the Linksys g AP only at Best Buy with rebates. My question is, since I don't need the routing stuff of the router, just the AP features, is there any reason not to get the router over the AP since it is cheaper? As far as features and performance go as an AP, are they identical?
