Fix Laggy Internet With These 9 DIY Wi-Fi Extenders

As essential as it is, Wi-Fi can be pretty erratic. The bandwidth strength can be affected by many things, from owning too many household appliances and electronics to having a mirror between the room you’re in and the Wi-Fi router.

A Wi-Fi extender, also known as a repeater, is the fix for laggy Wi-Fi or network blind spots in your home. While you can always buy one, building one yourself is pretty fulfilling and will save you some bucks. Check out the ideas below to build yourself a Wi-Fi extender. Some are so easy to make, they’ll take less than ten minutes.

For instance, if you find ads annoying, you’ll be glad to know it has some ad-blocking features. Plus, it runs on highly customizable software.
