I have AT&T Uverse fiber which consists of a fiber run that terminates into an ONT, which is great, but I’m forced to use AT&T’s garbage equipment, which is not great. My UniFi Dream Machine Pro can run wpa_supplicant, which could theoretically masquerade as AT&T equipment allowing me to connect directly to the ONT.

Theoretically, these are the utilities I would use to accomplish this.
