Why Storms Knock Out Some Internet Connections and Not Others (2026 Guide)

Internet service providers that use a wired connection offer the greatest stability in rough weather conditions like storms, rain, or harsh winds. This is because wired internet providers, such as Spectrum Internet, are largely shielded from the elements. On the other hand, wireless internet providers that use satellite or 5G fixed wireless technologies are most affected by storms because they use signals that travel through open air, where rain and wind can interfere with them directly.

Yes, weather can disrupt your internet service through power outages or physical interference.

Wired connections, including fiber-to-the-home (FTTH) and hybrid fiber-coaxial (HFC), are largely insulated from power outages and physical interference because their cables are buried underground. Wireless connections, such as satellite, fixed wireless, and 5G home internet connections, are most vulnerable to changes during inclement weather because their signals travel through rain, wind, and even trees to reach your home.

The table below shows how each major internet connection type holds up against storm-related weather conditions:

Wired internet services that use FTTH and HFC technologies are the most reliable during storms. HFC internet is a cable technology that most major internet service providers, like Spectrum Internet, use to provide their services. It uses a core fiber network that runs to a neighborhood node, which then switches to coaxial cable for the “last mile” to your home.

Wired internet is more reliable because:

• The core fiber infrastructure is buried underground, protecting it from falling debris or any damage caused by stormy weather
• Even where the line running into your home runs aboveground, it's still a physical cable rather than an open-air signal, so it's not vulnerable to the rain fade or interference that affects wireless connections

Note: All internet connection types have their weak spots. A fiber or cable connection can go down during a storm if there’s a power outage at a local network node or at your home.

Wireless internet services like satellite, 5G, and fixed wireless internet transmit data via radio frequency signals that travel through the open air to reach a dish or antenna at your home. Rain, snow, and even dense cloud cover can interfere with those signals, causing the internet speed to slow down or break the connection entirely. This effect is called rain fade.

For satellite internet, high wind can also physically shift a satellite dish out of alignment with the satellite it communicates with, which might require a technician visit to correct.

When electricity is interrupted, modems, routers, and neighborhood network equipment all go offline regardless of connection type.

High winds, falling branches, and flooding can damage aboveground lines or outdoor infrastructure.

Rain and humidity can seep into copper lines and some cable networks, degrading the signal and causing intermittent slowdowns or outages.

When a storm keeps everyone in your neighborhood indoors at the same time, the volume of streaming, video calls, and general browsing can exceed local network capacity, slowing speeds for users in the area.

Strong gusts can shift a satellite dish out of alignment, breaking the connection and requiring a technician to realign the equipment.

Here are our expert tips for staying connected during a storm.

If you're dealing with more than two or three weather-related outages a season, that's a signal your connection type could be the problem. HFC providers like Spectrum Internet run their core network through buried fiber, so most of the infrastructure never has to withstand wind or flooding in the first place.

Once you've settled on a wired connection, the remaining choice is what plan to get. We recommend getting:

• 500Mbps for small to medium households with multiple people streaming or working at the same time
• 1,000Mbps for large households with several power users who work from home, use smart-home devices, or play multiplayer games
