A Day Full of Comcast

Fearing that Comcast might show up without warning, I arranged my day so that I could spend most of it at home. But there was an 11am meeting I really needed go to to. Fortunately, we got done by 11:20, and then I rushed home again.

And, wouldn’t you guess, there were two trucks in front of my house when I got home. The guys said they had been trying to call me – on my home number (although they didn’t leave a message).

We agreed what they would do, namely run the new cable but leave the old one in place for the next Comcast guy to do the hookup. This was consistent with what everyone else who had come here or discussed it with me had said. So I went to my study and started working away.

Then the Internet went dead.

When I went outside I discovered the guys had pulled down the cable. Don’t worry, they told me, we’ll put in a new one and reconnect it so you won’t need to have another appointment. While being threatened with not having another Comcast appointment is like being told you may not need to have that root canal after all, I still worried. Does the contractor know how to connect up a cable? It’s not rocket science, but still, everyone else had been adamant that this was a task for a Comcast tech, not a Comcast contractor.

Meanwhile, I had a look a the trench which the team seemed to be digging with its hands. It seemed very shallow. How deep is it, I ask? Four to six inches, I’m told. So much for Comcast shovel technology not being adequate to dig a trench.

How long to make the new connection? I asked. A few minutes they say.

And indeed, in less than 10 minutes they said they were done.

So I tested it. Google strained to come up. Things were sloooow.

I ran a speed test. Ping was great: 5ms. Download was awful, 0.13 Mb when I’m paying for “Blast+” that promises 50Mb in burst mode. Upload was great, 11Mb. The last time I saw this combination of slow download fast upload it was a modem sync issue, so I power cycled the modem. Meanwhile, the contractors call in for a tech who they cheerfully promise will arrive sometime later today, undoubtedly, think I, while I’m going to fetch my son from school. That next Comcaster, the contractors said, is going to make some sort of more direct connection on the pole.

Don’t worry, it’s all outdoor work, you don’t need to be home.

I shuddered. I’d heard this before.

The modem finished its power cycle but there was no change on the download number. I ran a 50′ cable direct from the modem to a desktop, cutting out the router and the network from the circuit. This raised the download speed to 0.43 Mb, which while a vast improvement in percentage terms was still not anything like the speeds I had been getting yesterday. I ran the test several times, and managed to get over 1Mb downstream once. It still felt like a modem issue to me, and I wondered if maybe we just had to ask Comcast to resynch on their end. The tech says he’d try reinstalling the connection, just in case.

And, yes, whatever he did made a difference. Now with the PC directly connected to the modem I get about 10Mb down, and 11.75Mb up, about 20% of the download speed I previously enjoyed. And the contractor goes away, satisfied his work is done.

On the theory that this might be a modem issue, I called Comcast tech support (I get the Philippines call center), and the tech sends a refresh code down the line to the modem. This has no discernible effect. We try several different things including multiple reboots of the modem and one of the router, direct connections, network connections. The only thing I learn of interest is that one of my 50′ Cat 5e cables has a bad clip. 1 All in all, we spent a good 45 minutes doing things that maybe ought to have worked, but don’t. The only thing I don’t manage to do is unscrew and reattach the coax connection to the modem, which I’m told might help somehow. I can’t do it because the original installer screwed it on so tightly that it is un-moveable. I hope the next team will have the right tools.

The phone tech tells me to tell the repair guy – who she tells me is scheduled to come between 2-6, a window that includes the school run – the following: “Modem is active and online, but it is not showing a stable connection from the server. Have the tech disconnect the coax to reset the connection. Ask them to call tech support so they can monitor connection.”

And there it sits for a couple of hours when, miraculously, a Comcast tech and his assistant show up at about 3:15, that is before I’ve left to do the school run. I explain the problem. I show them the above quote from the phone tech, which they say makes no sense to them. Surveying the back of the house, they note that the previous crew did not in fact take down the old cable so much as cut it, leaving a big piece hanging precariously, one that they then tied my new line into. The new crew brings out a giant ladder to climb up and attach the coiled up part of the new cable directly to the Comcast line high on the pole. This is no mean feat given that there is a small jungle around the base of the pole, including several trees, making it tough to get the ladder into place.

And after about 20 minutes they’re done. They test the signal at the house, and again at the modem, and its strong. Sure enough, speedtest (via the network) is now at 43.24 Mb down and 9.7Mb up; ping is up to 9, but who’s counting? Some of that speed may be illusory due to burst mode, but it’s still good. Looking at my modem diagnostics, I discover I now have IPv6 — which I didn’t have in December — and after tweaking my Tomato settings on my router to DHCPv6 with prefix delegation — I confirm this via test-ipv6.com.

So it’s all good. Well, all good except for one thing. During all this excitement, the air conditioner stopped working. 2 The a/c repair guys are busy today but say they will come tomorrow.
