I have had no trouble connecting my Eris to my WiFi routers running WPA2 Personal (I use AES rather than TKIP, but that should not matter.) So long as the routers are not 802.11N only, or not 802.11A, it should work. (Mine are set to 802.11 b/g/n mixed mode.) I've also connected to others running WEP and WPA Personal.
