Re: [Connectivity] Sudden spike in DCC's, Schaumburg IL I'm on the NE side, near Schaumburg/Plum Grove roads. I had to power-cycle the modem to get it back on-line that one day. The first time it didn't take. I tried again a few minutes later, and it connected, but didn't get the time sync. It took a 3rd try to get it back to normal.
A minute or two after the reconnect, it did a DCC (seemed to confuse the heck out of my VPN, which may have been in the middle of negotiating the connection), but didn't change again for nearly 24 hours. Since then, it's more or less back to constant DCC's. Had one just a few minutes before posting this.
The DCC not only changes the downstream, but may change the upstream. Mine seems to sometimes use 2.56MSym/sec (Channel ID 4@29.6MHz), and other times use 5.12MSym/sec (Channel ID 3@34.4MHz). Downstream moves between 693, 699, 705 and 711MHz.
This is with an SB5120. I've had it for about 3 years. Signal levels are more or less the same on all channels, within 1dB or so.
Edit: Forgot to mention that I also get T3's at times, often while it's negotiating the DCC!! |

Hickory, NC | That's interesting. Come to think of it, I had to power cycle my modem twice as well. I just noticed that my upstream is now at 32QAM and 5.12MSym/sec on Channel 3. When I was on Channel 4, it was only at 2.56MSym/sec. as well.
Comcast is definitely screwing around and needs to get it's act together. It's really irritating me.
I am just west of Roselle Rd. and Weathersfield Way. off of Sienna Dr.
My log is still blank, so I have no idea what is going on  |
