I'm in Massachusetts with a Comcast high speed internet account. I use a Toshiba pcx 2200, which is a docsis 1.1 compliant modem.
For years, it was providing me with up to 4 mbit downloads and 384 k uploads.
A few months ago, Comcast sent its customers a letter saying they have raised their download and upload speeds. I don't know if the download speed increased, but the upload speed increased substantially, and was well over700kbits per sec for more than 2 months.
(just to fill out the picture, the modem goes to a router, the router has two computers and a slingbox connected...and I watch the output of the slingbox from an out of state account -- slingbox reports the bit rate, and the picture quality is notably different when more than 600kbits per sec is pouring down the lines)
A week or two ago I noticed the slingbox picture deteriorate, and noticed that the bit rate being sent out by my comcast account is about 350 kbits.
So this weekend I went home, did a speed test, rebooted the modem, did another speed test, and when I saw a 2.4 meg download speed max on various speed tests and 350K upload speed, I called Comcast. They told me my config file is just fine and I'd have to have a cable guy make a house call. He did, verified that the hookup is OK and that the signal strengths are OK.
Now I have a few questions.
Does it strain belief that the Toshiba modem is working "fine" but at half speed? I find it hard to believe, but not impossible.
Next question. On my out of state account, I have a Motorola 5120, and it's also registered with comcast. When I bring it home and plug it in, what will happen?
I figure there are 4 possibilities.1)It could be that the motorola won't work at all until I call comcast and talk with them.
2)It could be that it'll give me 6 meg down and one meg up, which would tell me that my toshiba really is kind of sick.3)It could do 4 down and 350 up, which would mean that it's being provisioned the same way by comcast that it's provisioned out of state and I'd have learned nothing.
4)It could do 2 down and 350 up, which means comcast's config file is screwy.
Any thoughts on what will happen and on whether my thoughts are sensible?
