T-Mobile LG G2 (D801) will not connect to home WiFi.

[AC Question]

Since I got home two weeks ago, my phone has been having issues connecting to my home (Comcast) internet. Sometimes it will connect, most times it won't. When I have the issue, my phone acts like it's trying to connect for a second, then goes back to either saved or disabled status. I've called T-Mobile, LG, and Comcast and tried a dozen of their bogus tricks, but the only "viable" solution I've been given is a factory reset on the phone. Does anybody have any other tips/tricks?
