signal-1m-good-two-weeks
Did you know that your cable signal gets stronger as the weather gets colder? Here's a graph of signal strength on my cable modem from the last month. The bump at the end comes from the cold snap in the last day, where it was around 32°F (0°C) at 6 PM yesterday, then got down to about -5°F (-21°C) around 12 hours later. You can also see that the temperature had been getting warmer gradually in recent weeks. The orange peaks toward the middle of the graph were occurring around 7 AM on cold mornings in February where the temperatures were around zero degrees Fahrenheit.
Blue is transmit power (lower is better). Orange is receive power (higher is better, though it shouldn't really go past +8 or +9). It appears that the received signal more than doubled in strength (since dBmV uses a logarithmic scale, as far as I can tell).
Roughly the first half of the graph covers a period when I was having lots of trouble with my cable signal. About a week into the graph, I had someone come by to fix it, but it seems that the issues weren't fully resolved until about a week later.
