Problem one night while playing comp in Overwatch on my new gigabit service, I lost Internet connectivity. It was down for about 5 minutes. I logged onto my AT&T Router Gateway (RG), and low and behold, they rolled out a new firmware which caused my RG to reboot. So, I ordered this cheap little Qotom mini computer from China. I installed pfSense and followed instructions at https://github.com/aus/pfatt. So far, so good. No more AT&T pushing firmware to my RG unannounced. If a new firmware comes out, I can just install it myself.
