Keep Internet During Texas Storms
Winter freezes, hurricanes, and tornadoes knock out Texas internet every year. Here is how to prepare: backup connections, battery setups, and provider outage history so you stay connected when it matters most.

Texas Storm Threats to Your Internet
Winter storms (Ice/Freeze)
Risk: Power grid failure, ice on lines, frozen equipment
Example: February 2021 freeze knocked out power for 4.5 million Texans for up to 5 days. Most internet service depends on electricity — when the grid went down, so did broadband.
Impact on internet: Fiber and cable both go down without power. Cell towers have 4-8 hour battery backup. Satellite dishes can ice over.
Hurricanes (Gulf Coast)
Risk: Flooding, wind damage to lines/towers, prolonged outages
Example: Hurricane Harvey (2017) caused internet outages lasting 2-4 weeks in parts of Houston, Beaumont, and Corpus Christi. Flooding destroyed ground-level equipment and underground vaults.
Impact on internet: Fiber lines survive underwater but junction boxes flood. Cell towers lose backhaul. Cable infrastructure suffers the most flood damage.
Tornado season (Spring)
Risk: Localized destruction, downed power lines, tower damage
Example: North Texas tornado outbreaks regularly damage above-ground infrastructure. Outages are intense but localized — typically 1-7 days for affected areas.
Impact on internet: Above-ground cable and DSL lines are most vulnerable. Underground fiber survives unless the home connection point is destroyed. Cell towers with generators restore service fastest.
Backup Internet Options for Storms
T-Mobile 5G Home Internet (backup line)
Best for: Primary backup for any home
Keep a T-Mobile 5G gateway as your storm backup. No contract means you can activate it before storm season and cancel after. During the 2021 freeze, T-Mobile cell towers with generators restored service 24-48 hours before wired ISPs in many areas.
Starlink (with battery backup)
Best for: Rural areas and prolonged outages
Starlink works independently of ground infrastructure — as long as you have power and a clear sky, you have internet. Pair with a portable power station (Jackery 1000+, ~$800) for 8-12 hours of Starlink operation during power outages.
Mobile hotspot (phone tethering)
Best for: Short outages (hours)
Your phone is your first-line backup. Most plans include 15-50 GB of hotspot data. Keep a car charger or power bank ready. Works until cell towers lose power (4-8 hours without grid power) or become congested.

Router UPS Battery Setup Guide
Keep your home internet running during short power outages with a simple UPS battery backup:
Get a UPS battery backup for your router/modem
A basic UPS (CyberPower or APC, $60-120) keeps your router and modem running for 2-4 hours during a power outage. This covers most brief outages and gives you time to switch to a backup plan.
Size your UPS correctly
A typical modem + router draws 20-40 watts. A 600VA/360W UPS provides 3-4 hours of backup. If you add a mesh WiFi system, get a 1000VA/600W unit. Check the wattage label on your equipment and buy accordingly.
Connect ONLY networking equipment to the UPS
Do not plug your TV or computer into the UPS meant for your router. The more devices you connect, the shorter the battery life. Dedicate the UPS to: modem, router, and (if applicable) ONT (fiber box).
Add a portable power station for extended outages
For multi-day outages (winter storms, hurricanes), a portable power station (Jackery, EcoFlow, Bluetti — $200-1,000) can power your networking equipment for 12-48 hours. Solar panels ($100-300) can recharge it indefinitely during daylight.
Provider Outage History and Response Times
| Provider | Feb 2021 Freeze | Hurricane Response | Storm Preparedness |
|---|---|---|---|
| AT&T | 3-7 days in most areas | Mixed — prioritizes cell tower restoration | Deploys mobile cell towers (COWs) within 24-48 hours to disaster areas |
| Spectrum | 2-5 days in most areas | Significant outages in coastal areas | Stages repair crews pre-storm; opens WiFi hotspots for affected customers |
| Frontier | 4-10 days (slowest restoration) | Limited TX coastal exposure | Fiber network is resilient but restoration crews are slower than larger ISPs |
| T-Mobile | 24-72 hours (fastest cell restore) | Generator-backed towers restored first | Best storm response — mobile generators, satellite backhaul, rapid tower restoration |
| Starlink | Unaffected (satellite-based) | Works if dish has power and clear sky | Independent of ground infrastructure; only fails with prolonged power outage or dish damage |
Storm Internet Prep Checklist
UPS battery backup connected to modem and router (test monthly)
Portable power station charged to 100% before storm season
T-Mobile or backup cellular hotspot ready to activate
Phone fully charged with car charger and power bank available
Provider emergency numbers saved offline (not just in your phone contacts)
Know your provider outage map URL (bookmark it on your phone)
Download important documents/files offline before the storm hits
Have a battery-powered or hand-crank radio for emergency alerts
Storm Internet FAQ
How do I keep internet during a Texas power outage?
A UPS battery backup ($60-120) keeps your router running 2-4 hours. For longer outages, a portable power station ($200-1,000) extends that to 12-48 hours. Your phone hotspot is your first-line backup. For multi-day outages, T-Mobile 5G ($50/mo, no contract) or Starlink with battery backup provides independent connectivity.
Which internet provider is most reliable during TX storms?
T-Mobile has the fastest storm response — cell towers with generators restored service 24-72 hours ahead of wired ISPs during the 2021 freeze. Starlink is unaffected by ground infrastructure damage but requires power. Among wired providers, AT&T and Spectrum typically restore service 1-3 days before Frontier.
Should I get Starlink as a storm backup in Texas?
Starlink is the most independent backup option — it works when all ground infrastructure is destroyed. Plans start at $50/mo with $175 equipment. Pair it with a portable power station ($200-800) for multi-day outages. For most Texans, T-Mobile 5G backup ($50/mo, no contract) is also an affordable storm backup.
Will my internet work during a Texas hurricane?
Probably not for the duration. Most wired internet (fiber, cable, DSL) goes down within hours of a major hurricane due to power failure and infrastructure damage. Cell towers have 4-8 hour battery backup. Starlink works if the dish has power and is not damaged. Plan for 3-14 days without home internet during a major Gulf Coast hurricane and have a cellular backup ready.
