Thanks. I'll check into this. However, we have several iPhones/iTouches and all connect perfectly (but I'm using WEP because of the prontos). The router does have two SSID (2.4GHz and 5GHz). Use the 5Ghz for other things as well as an additional 2.4 GHz guest network. Has been a solid router except having to use WEP on the 2.4Ghz network because of prontos. I know that phillips use to recommend setting up a different network just for the prontos. However, with all the integration from the pronto to my home network, this really doesn't make as much sense (at least for my setup).. SJ
