Why Your Stream Breaks in Winter

The failures are outside your house

Every seasonal streaming failure in this list happens between your home and your provider, before any streaming service is involved. That is worth establishing first, because the instinct in January is to blame whatever changed most recently, and usually nothing did.

The distinguishing sign is that your internet itself is affected — web pages slow, video calls drop, downloads stall. If only the stream is broken and everything else is fine, winter is not the cause.

Ice on aerial cable

A great deal of Canadian cable and telephone infrastructure is aerial, strung between poles. Ice loading physically stresses those lines, and freezing rain in particular produces the failure pattern people notice: intermittent degradation over a day or two, then either recovery or an outright outage.

Older neighbourhoods have more aerial plant than newer subdivisions, which is why two households a few kilometres apart can have very different winters. There is nothing to fix at your end; this one is your provider's line.

Snow and ice on fixed wireless

A fixed-wireless antenna is a line-of-sight radio link, and accumulated wet snow or ice on the dish attenuates the signal directly. The characteristic pattern is degradation during and shortly after a storm, recovering as it melts.

If your antenna is reachable and safe to reach, gently clearing it helps. If it is on a roof, it is not worth an injury — and a provider can often see the signal degradation on their side if you ask.

• Degradation that tracks the weather forecast is almost certainly your antenna or your line.
• Degradation at a consistent clock time regardless of weather is congestion, not winter.
• Total loss with no internet at all is an outage — check whether the router has power first.

Power outages take the network with them

This is the one people forget. Your router, your modem and any mesh nodes all need mains power, and a fibre connection with a battery-backed terminal still fails if the router is dark.

A small uninterruptible power supply on the router and modem — the kind sold for desktop computers — keeps a household connected through the short outages that make up most winter interruptions. It is one of the cheapest resilience purchases available and it also protects the equipment from the surges that follow restoration.

What this means for a subscription

Prepaid terms run on a calendar, not on usage, so days lost to a regional outage are days you have paid for. In parts of the country with a genuine seasonal outage risk — much of Atlantic Canada, rural Ontario and Quebec during ice storms — that is worth factoring into how long a plan you buy.

It is also worth knowing before you report a fault: if the whole street is dark, nobody's streaming service is at fault.

Questions

Should I report a winter outage to my streaming provider?

Check your internet first. If web pages and video calls are also failing, the problem is between your home and your ISP and reporting it to a streaming service will not help. If only the stream fails while everything else works, then report it.

Does cold weather damage a streaming device?

Indoors, no. What cold affects is outdoor plant — aerial lines, antennas, and the equipment on the pole. Your Fire TV Stick is not the problem in February.
