This seems to be an issue with more people than just me, and i figured people on this site could help with it. So my friend has a smartphone, the LG Revolution 4g as he called it, and whenever he is on our house's wifi. He is successful when using 4g, but its just a hassle to use 4g when our internet is so fast, so if you know how to fix this kind of issue lemme know.
Info you are likely to ask for:
Cox high speed internet
Netgear router WNR1000v2
Something interesting that is likely related. I've checked the logs for the router and most times when his phone logs onto the wifi first it says "WLAN access rejected: incorrect security", and the next log he is assigned his usual local IP, generally about 20-30 seconds after the wlan rejection.
