AT&T vs Cox, like night and day
This is a fun graph. I connected to my neighbors' WIFI for then minutes to see how their network performs. They are in the same physical building and have the same cables / setup.
On AT&T, everything under 100ms, couple of spikes. No packet loss.
Connected back to Cox, Ping 100-300ms, 10-20% packet loss.
Looks like Cox has oversaturated their networks and AT&T has not.
