Sergio is my hero
I wouldn't normally post in the middle of the day, but I gotta say: Comcast tech guy Sergio is my hero.
He arrived on time, and he knew exactly how to fix my slow-downloading problem. He told me that around the time of the service outage a couple weeks ago, Comcast changed something; apparently nobody is entirely sure what happened or why it broke, and only a few customers were affected, but the tech service-call guys eventually figured out a solution. (For the geeks in the audience: it involves setting the MAC address of the router to be 1 higher than the MAC address of the cable modem. Sounds like FM* to me.)
Before he arrived, I went to the Hubris Communications Bandwidth Meter and was seeing speeds around 75kbps. After he left, I tried again and got a speed of over 3100kbps. (Which seems implausibly high, but another tool, Ridge, is showing peak download speeds up to about 500KB/s, which is indeed well over 3000kbps. And Toast.net's performance test is showing nearly 3000kbps. Four seconds to download a 1.4MB image file. As opposed to the several minutes it would've taken this morning.)
It's so nice to have a happy shiny speedy Internet again.
Now I want to call back Comcast and tell them to tell their phone support people that this is a known problem with a known solution and they need to stop telling customers it's their fault.
*My father used to occasionally explain that various things worked by means of "FM." I would ask, "What's that?" He would reply: "Fuckin' magic!"
