Simple Ways to Keep Your Internet On During Power Outages

Extreme weather can strike anywhere, anytime, and this summer may be one of the worst on record. Heat waves in particular can wreak havoc on already strained power grids, resulting in temporary blackouts.

When bad weather knocks your power out, it could disrupt your internet. There are a few ways, however, to restore and maintain your online connection, even if the power is still out.

If you’re reading this, your power may be out and you need to restore your internet connection quickly. In that case, I’ll get right to it: Here’s how to stay connected to the internet when you lose power.

Quick fix: Mobile hotspot and tethering

Activating a mobile hotspot on your phone essentially turns the device into a router, broadcasting its mobile internet connection for other devices to use. It’s not the same as your home Wi-Fi — speeds are likely to be much slower and will only support a limited number of devices — but it should get you by.

Tethering is similar in that it shares your phone’s internet data with other devices, but it does so via a wired (USB or Ethernet) or Bluetooth connection rather than Wi-Fi.

A few things to keep in mind when using a mobile hotspot or tethering:

• The connection only works until your phone dies. Consider charging it in your car (if you can safely access it) if your battery starts to run low before the power comes back on. 
• Having the mobile hotspot function on your phone doesn’t necessarily mean the service is included with your cellular plan. 
• You’ll be using your phone’s data. If you have a cap, using a mobile hotspot can put you over the limit, which can result in added fees or throttled speeds. Even if your cellular plan offers “unlimited” data, there may be a soft cap or a limit specific to mobile hotspot use. 

Contact your cellular service provider to find out if mobile hotspot use is included in your plan and if any data limits apply. If you have a data cap, check out CNET’s guide to managing your data use.

Automatic fix: Cellular internet backup

Select internet providers offer a separate cellular plan or service add-on to keep you online. Xfinity’s Storm-Ready Wi-Fi and T-Mobile’s new Home Internet Backup plan provide equipment and a cellular connection, for example, when your standard connection goes down.

Storm-Ready Wi-Fi is available to Xfinity Internet customers for $7 a month for 36 months or a one-time fee of $252 for the rechargeable 4-hour battery backup. When the power goes out or your cable internet connection is lost, internet service automatically switches to a 4G LTE cellular connection with unlimited data.

T-Mobile offers a 5G home internet connection (where available) but with a data cap and a slightly higher monthly fee. The Home Internet Backup plan includes 130GB of data and free equipment starting at $30 a month or $20 for T-Mobile voice customers. 

You will need power to the T-Mobile router, however, so if you intend to use your Home Internet Backup service during power outages, you may want to invest in a battery backup or other portable power device.

Long-term fix: Generators or other power sources

Getting power to the modem or router may be all you need to keep your internet going when the power goes out. 

In many cases, a local power outage doesn’t stop internet service from coming to your home. Wireless and fiber internet don’t need power to travel, though a power outage at the point of distribution may cause a temporary outage. 

Cable internet requires power to the nodes (connection points that send internet service along), but many ISPs will have a backup power source, enabling them to keep your internet service going.

So the problem isn’t necessarily getting internet service to your home; it’s how to use it. Without power to your modem or ONT device, you can’t connect to the internet and without power to your router, there’s no Wi-Fi.

Portable power stations and generators are ideal for continuously powering things like your refrigerator, heaters, fans or internet equipment. Here are some helpful links to finding the right power device for your home and needs.

What about battery backups or a UPS?

Rechargeable battery backups will keep your internet equipment running for a few hours at best before needing to be recharged. Without a power source, this can be difficult, but a solar battery may be the solution.

As for a UPS, or uninterruptible power supply, most devices aren’t designed to last more than 15 minutes or so. That’s long enough to save your work or send any last-minute emails before losing your connection, but not much more.

Keep connected and stay safe

Maintaining your internet connection is important when the power goes out, particularly if you’re using it for information or communication, but safety comes first. Always use caution when dealing with electrical equipment, and avoid tampering with any internet lines coming into your home.
