I have a Netgear WNDR3400 router and I have very inconsistent results when trying to connect to it. We have a PC that will connect to it okay, a Mac Pro that connects okay, and then an iPhone and MacBook - neither of which will connect. If I turn off the security settings, it will connect, so it makes me think it is an issue with the encryption type. The choices are: WEP WPA-PSK (TKIP) WPA2-PSK (AES) WPA-PSK (TKIP) + WPA2-PSK (AES) I have no idea what any of these options mean... I am currently using the WPA2-PSK (AES) option. Is there any advantage/disadvantage to any of these?
