If dealing with comcast, I don't know their peering infrastructure as much as cox's, but they're not typically local, and probably transport you to another state for egress. This isn't much different from cox, they dump you out LA or Dallas, usually the former than latter, only cbs and other direct peering relations egress actually in phoenix.

Back in June comcast raised my connection speed to 150Mbps. Two
weeks ago it went back down to 100. I called to complain and was
told I was supposed to be getting 100Mbps. I finally got someone
to admit that my connection speed should be 150, but I'm still
getting 100. <br>
<br>
I didn't make any changes to the network, but something could have
gotten changed. Is there anything i can look in network settings to
determine if something could be tweaked for a faster connection?<br>
<br>
I have an Arris SB6141 modem and an ASUS RT-ACRH13 gigabit router.
The modem (SB6141) supports speeds up to 343Mbps down. KDE's
network manager shows the MTU setting is set to Automatic and the
box is checked to allow auto negotiation.<br>
<br>
I did install Kubuntu 18 after the increase to 150Mbps. The speed
did not drop until a month or so after Kubuntu 18 was installed.<br>
<br>
Since the installation, the ethernet connection is no longer called
eth0. Now it's called enp4s1. Is that some new way of naming
network devices? I don't really care what it calls the parts as
long as they work. I can still use netwatch, but I have to give it
the enp4s1 string as it expects eth0 unless told differently.<br>
