Default AT&T GPE Radio Question

Hey guys, I have an AT&T M8 that I have done the GPE conversion on. Lately I have to keep toggling airplane mode at my house for the WiFi to work correctly. However, if I look at the quick settings, the bars are not orange.

I HAVE switched to the AT&T radio already, so I am using baseband version 1.16.21331931.LA11G_20.31A.4145.02L

Is there a newer/different radio that I should be using?

Thanks in advance for the help!
