[Connectivity] I hate cold weather

I hate it when the temperature gets near 0. I always run into upstream issues. Connection goes dead, but I can see the link light still blinking as normal for awhile. Then it goes into a reconnect, but sits at upstream blinking for about 5 minutes. I've had this issue for several years and several different modems. It's especially bad this year with the unusually cold weather. Upstream signals are all normal, around 41-42.
