How Weather Affects Internet Performance: Fiber vs. Cable vs. Satellite
If you live in West-Central Wisconsin or run a small business here, the weather is much more than small talk around the water cooler. Heavy snowstorms, ice storms, summer thunderstorms, and high winds can all affect your internet service. During any of these severe weather events, you’ll want to understand how weather and internet speed mix so you can take action.
In this blog post, we’ll cover how weather impacts fiber, cable, and satellite internet, what’s actually happening during an internet outage vs slowdown, guidance on Wisconsin-specific storm prep and connectivity strategies, and household checklists for fiber, cable, and satellite customers.
TL;DR: Weather’s Impact on Internet Service
Not all internet services respond to bad weather equally, making an internet reliability comparison important for Wisconsin households. Let’s break it down:
- Fiber internet is the least likely to slow down or experience outages and is widely considered fiber optic weather resistant.
- Cable internet during storms usually performs as expected, but severe weather can impact stability. Cable networks can experience temporary rain and snow internet problems, even when service seems normal.
- Satellite internet in bad weather is the most likely to experience degraded performance due to atmospheric conditions. Satellite users should always plan for potential slowdowns in heavy precipitation due to rain fade internet.
The Science of How Weather Interferes With Connectivity
Weather affects your internet in multiple ways, and understanding the science can help with troubleshooting and planning.
- Precipitation (rain, snow, ice): Water absorbs or reflects radio frequency signals, causing slower speeds for satellite users or temporary drops in cable performance. Ice adds weight to aerial fiber lines and satellite dishes, stressing hardware.
- Wind & falling limbs: Strong gusts can damage lines, loosen connectors, or bring down tree limbs onto cables. Wind-related outages can affect fiber and cable alike.
- Lightning: Electrical surges can damage modems, routers, or outside plant electronics if devices lack lightning surge protection.
- Temperature swings: Expansion and contraction can stress connectors, while extreme cold may reduce battery life in Uninterruptible Power Supply (UPS) units or enclosures, causing power outage internet scenarios.
Tip: If your internet slows during bad weather, first determine whether it’s a true outage affecting all devices, or a temporary slowdown caused by congestion or signal interference.

Fiber Internet vs. Weather
What Fiber Resists Well
Fiber optic service is not weatherproof, but it’s as close as you can get.
Fiber optic cables transmit light instead of electrical current, so they are not susceptible to electromagnetic interference or power surges caused by electrical storms or down power lines. This is an important advantage during a power outage internet scenario.
Most fiber is buried underground or encased in protective materials, which makes them far less vulnerable to wind damage to lines, falling ice, or debris.
One of fiber’s biggest benefits, though, is consistent performance, thereby reinforcing its reputation as a fiber optic weather resistant option.
What Can Still Go Wrong
Fiber can experience some issues in extreme conditions:
- Power outages: If your modem or neighborhood hub loses power, your internet service will stop until power is restored.
- Line damage: High winds, falling tree limbs, or vehicle accidents can sever fiber lines.
- Snow and ice accumulation: Heavy snow or ice can weigh down aerial fiber routes in rare cases.
Home Checklist for Fiber Customers
24-7 & West Wisconsin Telcom weather-proofs your connection where service enters your home, but you can take extra steps to improve resilience.

- Contact 24-7 & West Wisconsin Telcom for advanced internet troubleshooting

Cable (Hybrid Fiber-Coaxial HFC) vs. Weather
Cable internet performs reliably most days, but storms can expose vulnerabilities unique to coax-based networks.
Typical Weather-Driven Issues
Neighborhood cable hubs rely on electricity. If power goes out, downstream customers lose service, making cable internet during storms more susceptible to outages.
Moisture intrusion is another concern. Water ingress coax is rain or melted snow entering connectors that have been compromised causing noise and packet loss. This is one of the most common rain and snow internet problems for cable users.
After power returns, multiple homes may power on routers simultaneously, temporarily overwhelming the local node and causing slower speeds or packet loss. The flood of usage overwhelms node capacity resulting in latency due to congestion. Run two wired speed tests post-storm and capture screenshots for support. This helps 24-7 & West Wisconsin Telcom quickly distinguish an internet outage vs a slowdown.
Home Checklist for Cable Users
- Replace old or corroded coax jumpers
- Avoid running indoor coax outdoors for extended distances
- Plug your modem and router into a UPS with lightning surge protection
- If speeds dip after storms, run wired speed tests and document results before contacting support
Satellite vs. Weather
Satellite connections rely on a clear satellite line of sight between your dish and orbiting satellites.
Rain and Snow
Rain, snow, ice, and dense cloud cover weaken this signal, a phenomenon commonly known as rain fade internet.
Heavy snow and ice buildup can also shift dish alignment, while strong winds may further obstruct signal clarity, making satellite internet in bad weather the most weather-sensitive option.
Ice, Wind and Alignment
Ice accumulation or high winds can slightly misalign the dish. Snow can cover the feed horn, interrupting the signal. Using dish heaters or larger dishes where available helps prevent rain fade internet and reduces outages during Wisconsin winter storms.
Home Checklist for Satellite Users
- Keep a soft brush handy to remove snow (no de-icer or chemicals)
- Ensure clear satellite line of sight and trim growth in summer
- Consider larger dish/heater kits if available in your area

FAQs
Does cold weather slow fiber?
Fiber won’t degrade in weather and cold temperatures don’t affect fiber speeds. Power outages at your home or neighborhood node will cause service disruptions as will accidental physical damage to aerial fiber from ice, snow, or building debris.
Why is satellite fine in clear winter but bad in heavy snow?
Satellite internet requires line of sight to the satellite. Heavy snowfall, ice build up on your antenna, and thick cloud cover all weaken the signal which results in slowdowns or outages. This issue is often referred to as rain fade internet.
Can storms slow cable but not fiber on my street?
Yes. Cable internet relies on neighborhood amplifiers and coaxial lines that require power to operate. Storm-related power outages or water ingress into coax can slow cable, while fiber continues to operate because its optical lines don’t require electricity and are generally more protected from weather.
Do whole-home surge protectors help?
Whole-home surge protectors may minimize damage due to lightning-caused surges and power fluctuations. They will, however, not protect from all surges such as direct surges through outside lines or severe lightning strikes. Using a UPS for router/ONT provides additional protection and continuity during short outages.
Is WiFi worse in storms?
Indoor WiFi generally isn’t affected by rain or snow. Slowdowns during bad weather are generally related to losing power/internet or internet service provider (ISP) outages instead of weather interrupting your connection. Satellite connections might see some degradation, but fiber and cable WiFi inside should not be affected.
